Script-fu is still available in 2.99 and nowadays we get a very active
contributor for it. So it's even improving. :-)

As for G'MIC, it is available for GIMP 2.99 too, though maybe not on all
platforms, and it probably "breaks" at nearly every dev release (as we
progressively change the API here and there). So there is indeed often a
short span of time where it's non-available. Of course, not advising you to
use 2.99 either as it's still marked as "unstable" releases (so to be used
carefully), but just saying that these 2 points are not hugely broken and
there is no doubt to me that they will will be available with GIMP 3.0 (and
no API break for a long time then!). :-)

Hey no problem don't worry. Neither your email nor the one from the other
person were rude or anything. I was just annoyed by the fact they were sent
privately and it's true I'm quite tired these days.
Anyway thanks for understanding and sorry to read about your health issues.

Re: [Gimp-developer] [Gimp-user] Discontinuation of mailing lists and moving to Discourse

[Jehan Pagès via gimp-developer-list]

s the address I historically used
to subscribe to mailing lists. I am still receiving uncountable numbers of
emails daily.
And now you'll understand why I am doing a single and hopefully last answer
on this topic. I'm just tired and don't want to paste the same email twice
(or more).

Actually sending private emails, you kind of made a counter-argument
against mailing lists where it is indeed quite common that people feel they
can just continue discussions in private. But there is a reason why it's
public: anyone can join in, help and contribute to the discussion. No need
to involve a single person only (forbidding others to help by going
private). In GIMP, we work in full transparency, with public
infrastructure. We don't want private discussions, and unfortunately as you
showed, this is often what some people believe they can afford to do with
emails. So you both shot your opinion in the foot by telling me that
mailing lists are better while deciding not to use these to tell me this. 🤣

So yes, bottom line: mailing lists will be gone. It's not a private
decision from anyone in GIMP team (I got notified today myself of the
end-of-month deadline), though clearly nobody fought against it either.
It's not really something we can or want to control so there is really no
need to give counter-arguments here. If you really wish to do so, you are
welcome to ask the GNOME Infrastructure team. If they back down from their
decision, we'll happily comply and keep the mailing lists.

Well basically same as you always did, except that now it will be on one of
the Discourse instances, such as the pixls.us one or the GNOME one. Instead
of being subscribed to a mailing list, it's on Discourse (which is
basically a modern-time forum, as I see it), on which you'd have a
login/account. :-)

[Gimp-developer] Discontinuation of mailing lists and moving to Discourse

[Jehan Pagès via gimp-developer-list]

Hello everyone!

The GNOME Foundation has been moving all its discussions to a Discourse
forum, progressively:
https://mail.gnome.org/archives/desktop-devel-list/2022-September/msg00018.html

We were informed today that they are on the last stage of this migration
and that all the mailing lists will be fully retired by the end of October.
This implies also all of GIMP and GEGL mailing lists.

Instead, people wishing to discuss about GIMP are expected to use GNOME's
Discourse instance. In particular 2 tags were created for us:

* "gimp" tag for GIMP-related discussions:
https://discourse.gnome.org/tag/gimp
* "gegl" tag for GEGL-related discussions:
https://discourse.gnome.org/tag/gegl

We don't have as many tags as we used to have mailing lists, just these 2,
but since all our lists are quite low volume these days, I didn't think it
was worth asking, at least for now. GNOME admins confirmed that it would
not be a problem to add new tags in the future if we ever decided we needed
more (e.g. having a "gimp-dev" tag or whatnot).

By the way, noteworthy information: GIMP has had already an official
presence on pixls.us Discourse: https://discuss.pixls.us/gimp/
We discussed among the team if it was worth having presence on both pixls.us
and GNOME discourse and we came to the conclusion that the audience is
different, therefore it is interesting to stay on both communities. For
discussion with existing GNOME contributors, translators and various GNOME
users for instance, they might be already on the GNOME Discourse. On the
other hand, pixls.us is a much more specialized forum/community on
Photography in particular, and is also probably more platform-independent
too.

Last but not least, as I expect that some people might prefer interacting
by email, I tried to look up what are the possibilities. This thread
"Interacting with Discourse via email" is of interest:
https://discourse.gnome.org/t/interacting-with-discourse-via-email/46

It didn't have the ability to create new threads easily, especially tagged
with the "gimp" keyword. Discourse has a way to create a topic on a
specific category but we couldn't find for tags, for instance you can send
an email to community @ discourse.gnome.org (note that it doesn't work for
every category, e.g. it didn't work for infrastructure; I haven't tested
others). With Andrea Veri, GNOME Infrastructure admin, we came up with a
special email hook: any email with "[GIMP]" in the subject will be tagged
"gimp".
Nevertheless you need to have level 1 trust level for this to work. We
aren't sure exactly what it means other than having participated enough
(whatever "enough" is) to the Discourse first. 🤷

See:

Yes we use libheif. We have no specific prefered encoder for HEIC. So
whatever is made available through the local libheif install, I'd say.

I discussed the topic of enum-type arguments in the MR opened by Lloyd:
https://gitlab.gnome.org/GNOME/gimp/-/merge_requests/709

Feel free to read the discussion, though I'll also try to re-explain it
here.

As a first disclaimer, I will discuss this with C code because I am
personally not interested into script-fu-only specifics, neither into any
language-specifics. This includes C itself (i.e. I don't care about
solutions which work only on C either), but C is our base language, which
is why it's our generic language here.
We used to have many bindings in many languages, most of them (but
script-fu) are now dead (development-wise) because they focused on logic
specific to the language (which is great and for sure has a lot of
advantages, don't get me wrong, but also means a lot more continuous
maintenance).

This is actually the current state of things currently in GIMP 2.99/3.0.

When we want a list of options (a.k.a. enum-like type) as argument, we
declare it as an int argument. And we list the values in the docs string:

  GIMP_PROC_ARG_INT (procedure, "preset",
 _("Source _type"),
 _("WebP encoder preset (Default=0, Picture=1,
Photo=2, Drawing=3, "
   "Icon=4, Text=5)"),
 0, 5, WEBP_PRESET_DEFAULT,
 G_PARAM_READWRITE);

On API/plug-in/script programmer side, it's ugly because it means that
people rely on meaningless integers and always have to refer to docs to
re-read existing code. Also it means if we forget to update the docs, the
possible values might be incomplete. Worse, for some procedure, the number
of options is so huge, we currently don't list them in the string docs.
This is the case of "pixel-format" in plug-ins/common/file-raw-data.c which
has 19 possible values. So I didn't even bother writing the docs, though
it's also because I was planning for better system to declare list of
options.

On GUI side though, we don't have such a problem because we have the API to
easily map int values to individual string items:

  /* Create the combobox containing the presets */
  store = gimp_int_store_new ("Default", WEBP_PRESET_DEFAULT,
  "Picture", WEBP_PRESET_PICTURE,
  "Photo",   WEBP_PRESET_PHOTO,
  "Drawing", WEBP_PRESET_DRAWING,
  "Icon",WEBP_PRESET_ICON,
  "Text",WEBP_PRESET_TEXT,
  NULL);
  gimp_procedure_dialog_get_int_combo (GIMP_PROCEDURE_DIALOG (dialog),
   "preset", GIMP_INT_STORE (store));

So my initial idea was to move this "store" list (but it will have to be
another type, not depending on GTK) into the declaration part of plug-ins.
This way, at least the problem of documenting the values and even managing
errors (non-supported values) is no more.
Then we would not have to maintain a huge docs for the arg (but smaller doc
strings for each values) and we can generate better docs for such
arguments. Though we would still have to deal with integer on caller side.
It would be better with semantic values.

An alternative could be to use string arguments (also associated to a
limited given list of allowed values on callee side), this would bring
semantic, using for instance "picture" as arg rather than whatever int
value is WEBP_PRESET_PICTURE.

In any case, the best would be to have real enum types declared and usable
on caller side too, hence using the same type on both side, and that brings
some semantic to the API. It seemed to me that it was not possible to
generate enum types dynamically, but Lloyd seems to think it is thanks to
GTypeModule. So let's see how it goes. :-)

I just checked old 2.10 plug-ins. I see PF_OPTION is a Python API thingy.
Apparently it was to make combo boxes from properties?

We can already do this in the 3.0 API using int properties. A bunch of
plug-ins already use this. For instance look at the PNG plug-in:
https://gitlab.gnome.org/GNOME/gimp/-/blob/cac7ed93a0debedf1c60c2e71dc9a038b3ffb454/plug-ins/common/file-png.c#L2280-2291

Now I am still planning to improve this, I think I explain this in some
report somewhere but I can't find it right now (or maybe I forgot to write
this down). Basically the idea is to move the int_store part from GUI into
the procedure definition (the query_procedure() method) as a complement of
the int argument:
https://gitlab.gnome.org/GNOME/gimp/-/blob/cac7ed93a0debedf1c60c2e71dc9a038b3ffb454/plug-ins/common/file-png.c#L274-279

Because right now, for people using the API in scripts, we have to list the
whole values in the argument description (i.e.:
https://gitlab.gnome.org/GNOME/gimp/-/blob/cac7ed93a0debedf1c60c2e71dc9a038b3ffb454/plug-ins/file-jpeg/jpeg.c#L234-237
) but this is very annoying, both for translation, keeping it up-to-data,
but also when the values list is very long (for instance, recently I was
updating the file-raw-data plug-in and one of the int arguments is such a
list of options and it's veryyy long.

If we can move this store list into the properties, it could make
everything easier.


> Some

The wiki on Gitlab was considered but it is a hassle to use because of
access permissions. Apparently you need to have Developer permissions to be
allowed to write on the Gitlab wiki too. It means we can't easily give
access to more people.

Yes, this is the goal. The full data has already been ported to Markdown
(and using the Hugo framework) to facilitate contributions.

Indeed there is no difference for plug-in creation depending on the
platform.

Now maybe the fact that the macOS DMG is signed means all the plug-in
binaries must be signed too to be run. I have no idea, but I guess it makes
sense in the security context of signature of binaries.

As Jacob says, if anyone has more information, we welcome contributors for
documenting OS-specific differences too, especially as we are currently in
the process of reviving our developer website where such information would
be definitely welcome. :-)

Indeed.

But adding and "fr.po" file there with some msgid/msgstr
> doesn't seem enough.


It must be "compiled" too. `.po` files are source for `.mo` (or `.gmo`)
files.
Also it must be in subdirectories (standard translation organizations). So
if your plug-in is called "my-plug-in", then the .mo file for French would
likely be in locale/fr/LC_MESSAGES/my-plug-in.mo

I am planning to make tutorials for all the GIMP 3.0 API for plug-in
creation, and more generally extension creation. This will include
localization.
We are currently also in the process of reviving https://developer.gimp.org/
(which is very outdated right now).

Anyway that's a lot of work being done right now. We can't give ETA, but it
will happen. :-)

That's actually one of the things I still have to review and make decisions
or changes about. Look at my little checkbox at the bottom of this comment:
https://gitlab.gnome.org/GNOME/gimp/-/issues/8124#note_1493804
The one box still unchecked says "Menu paths" which I believe is what you
are asking about.

Again, it's on my TODO, but I can't give an ETA. My hope is that I can make
time to finish this one for the next dev release. We'll see.

Sure. We now have someone new very recently who has been working on
compiling the dev code (finally!) for macOS. It's still a work-in-progress
but promising. Of course, the more we are, the better, so it should not
prevent you from helping too. This would be a great milestone, I don't
think I saw 2 active macOS code contributors at a time for the last 9 years
I have been around. 😲

Yes sure. But that's detail. Signing is already all set-up. Now what we
need to look at is to build and run (without crashing) GIMP dev code.
That's the next big thing. Signing is useless without this. 😛

Anyway as said on LinuxFr, discussing on #gimp IRC channel at irc.gimp.org
is probably the best (now soon going to bed and tomorrow might not be too
available during the day, but in the evening or next days, sure; you might
also be able to talk to lukaso, the other macOS contributor, on IRC too if
around).

It's hard, but I understand. You should never give up sanity (or anything
which makes your life nice to live) for a program.

I hope we'll find a nice new maintainer for GExiv2 and I wish you a good
continuation. Thanks for all the past work! And obviously you'd be welcome
if you want to be back (as far as I can say on GIMP behalf at least).

As for Shlomi Fish, one is indeed a nice and useful person going around in
the community for quite a long time. So it's a good start! 🙂

It's a third-party tool, not an official one. We don't have our say to what

This being said, someone could create a similar tool in Python or whatever
you want.

That's a good question. I have no idea.
In any case, if it were to be contributed as an official tool in the end,
your worry would be most valid as cross-platform code matters a lot. As
long as it's just a third-party tool, everyone may use whatever they want.

Actually creating procedure parameter in Python plug-ins is a bit of a
mess, because of various issues in pygobject.
Adding properties to the class is indeed not mandatory, we should be able
to just create a GParamSpec and use it in gimp_procedure_add_argument().

So we **should** be able to just write:

paramspec = GObject.param_spec_rgb("color",
>  "Color",
> "Color", true, red,
>
> GObject.ParamFlags.READWRITE)
> procedure.add_argument(paramspec)
>

Except it doesn't work because of a bug in pygobject:
https://gitlab.gnome.org/GNOME/pygobject/-/issues/227#note_570031

This is why I created gimp_procedure_add_argument_from_property() to grab
the GParamSpec out of a created class' property.

Now the question is: how do you create a property to a GObject class in
Python? Well it turns out documentation lists 3 ways to create a GObject
property:
https://python-gtk-3-tutorial.readthedocs.io/en/latest/objects.html#create-new-properties

I used the __gproperties__ one because it felt a bit more centralized and
easy to detect (also it's apparently the only syntax allowing to set
min/max values), but it turned out that I never managed to make a Gimp.RGB
property using this syntax. This is the reason why in Foggify plug-in, all
but the "color" property use the __gproperties__ syntax whereas "color" is
defined like this:

color = GObject.Property(type =Gimp.RGB, default=_color,
>  nick =_("Fog _color"),
>  blurb=_("Fog color"))
>

It looks like a limitation of this __gproperties__ syntax, but maybe I
missed something in how this syntax works.
And this is all why it's such a mess. Of course, maybe a best way might be
to define all properties with GObject.Property() syntax, then we don't have
discrepancy in code style (but then we also lose the min/max ability).



> 2. Is the Class name the Camel-style except "_" ?

Yes we use CamelCasing for class names in our Python code, I guess it's
just usage in Python (https://www.python.org/dev/peps/pep-0008/#class-names
).
Now we have coding style for within GIMP core code, but we don't mind what
third-party software developers want to use. We are really not into coding
style wars, only keeping consistency within a single codebase.

3. Can the procedure definition name include "_"?

Sure. Python doesn't forbid underscores in function names. Actually it even
advises using it in the same coding style document (
https://www.python.org/dev/peps/pep-0008/#function-and-variable-names). You
can see this is also the convention we are using in our Python code in
GIMP's codebase.

To be fair, I don't think I'd be a big fan of either VB or C#. This being
said, same as coding style, you are free to do and use whatever you want,
and I won't be the one to tell you it's wrong. If you make a great tool for
migrating third-party plug-ins into GIMP 3 API, we will even happily make a
mention of it on gimp.org when we are closing the release date! 👍

In GIMP 3, it is mandatory to have all plug-ins in an identically named
folder as the main script. This is to avoid making a mess in the root
plug-ins/ directory, and mixing files between plug-ins (which results in
DLL hell on Windows especially, for instance).

Most plug-ins can be actually ported in less than 30 min (let's say 2 or 3
hours for someone who does this for the first time by just following a
tutorial; nothing insurmountable). I say it by experience from having
ported a huge portion of core plug-ins.

Our API has been stable for a long long time. Actually the cases of broken
plug-ins which we can see here and there are plug-ins which have been
basically abandoned/unmaintained for years and years. In such case, first
there were deprecation warning triggering popups then much later, functions
were removed. So we are talking plug-ins which have not been updated for
like 10 or 15 years!

Sure. We did a choice of going with a cleaner API. Sometimes I wonder if
that was not a mistake and we should have tried compatibility as much as
possible. On the other hand, we would have lost so much. In any case, it's
too late now. We are not going to redo everything.

Also as said, porting is actually very quick. Some people already started
(there are a bunch of plug-ins with a GIMP 2.99.x version; even G'MIC can
work on 2.99.x). The base logics of our plug-in stayed quite similar. So
it's nothing too hard.

And once again, same as the v2 API has been around for more than 15 years,
I expect the v3 API to stay for quite some time. We are not planning to
break API all the time. 😛

Mostly yes. There will probably be some more changes so you will have to
change more from time to time until GIMP 3 release (when it will be
finalized).

Because of I think that the scripting is so far from GIMP 2.10 era... (Too

It's actually simpler in many ways, but yeah it changed (though bases
concepts still are the same). That's a fact. Also the Python binding used
to have some of the new features already (like dialog generation) which
makes the improvements less visible for people who were already making
Python plug-ins.

Are there any points to be aware of?

Not really. This is on my TODO list to write proper docs. We have some
starts in the devel-docs/GIMP3-plug-in-porting-guide/ folder in the
repository, but nothing yet which you can really call a proper
"documentation".

Is it premature? (Is it better to wait for a while? Will some change come?)

It's never premature to write docs. Sure there will be changes, and sure it
means some of the docs will be wrong and need to be changed before release.
But better start early and fix as we go than write dozens of pages of
documentation at the last minute.

This is actually a good way to contribute to GIMP with other than code. The
few random files we have in devel-docs/GIMP3-plug-in-porting-guide/ were
written by several people already. If you port your own plug-ins and want
to write documentation, do not hesitate. Right now it's a mess because
everyone wrote a bit of what they wanted, but with time and more people
giving time into it, the documentation will organize itself. 🙂

Definitely yes. I have started to fill the form (

Attached is my first try at filling the form. Would anyone mind review and

**Note**: I wonder if XCF should actually be considered *vendor* tree
(even if there is no vendor per-se and no organism behind).
Our XCF format is clearly tied to GIMP and will evolve with it. Wouldn't it
be somehow the definition of a vendor format?

# Required Parameters

**Note**: no idea how to fill these. They give RFC 2046 §1, and RFC 6838
§4.3 as references but these sections discuss format and such, but not
really what these parameters are (I have not read the full RFCs).

# Optional Parameters

**Note**: same as above.

# Encoding Considerations

binary

# Security Considerations

No active content or action of any kind is contained in an XCF file.

XCF files may contain any possible metadata (Exif, XMP, IPTC, and a
generic comment), which are usually found in all common image formats.
This may reveal very sensitive information on author's name, address,
position, movements, owned material…

Compression is used to store image tile data. The 2 possible compression
formats so far are RLE and zlib compression. Image data can be enormous
once uncompressed, especially for work images, which can contains dozens
of layers. Since the format compresses the data per tile blocks of width
and height of up to 64 pixels, the reading software will uncompress
progressively, hence with the opportunity to qui

Indeed I think that  image/x-xcf is the right one. I didn't even know of

Thanks to Claude Paroz for taking care of this last point!
Now the gimp-help module on Damned Lies follow both the `master` and
`gimp-help-2-10` branches: https://l10n.gnome.org/module/gimp-help/

Documentation is now fully ready to diverge. It also means anyone wanting
to help contribute on documentation for future GIMP 3 is very welcome to
start opening new sections/pages for the new features coming with GIMP 3,
even when they are still unfinished. To get a quick idea on these, the 3
development versions already released are a good start:

https://www.gimp.org/news/2020/11/06/gimp-2-99-2-released/
https://www.gimp.org/news/2020/12/25/gimp-2-99-4-released/
https://www.gimp.org/news/2021/05/08/gimp-2-99-6-released/

To go further, the NEWS file is obviously a bit more complete:
https://gitlab.gnome.org/GNOME/gimp/-/blob/master/NEWS

And finally do not hesitate to ask us directly and discuss with us when you
don't understand something. The current mailing list is obviously a good
discussion point though the IRC channel may be a bit easier to catch people
(#gimp on GIMPnet).

It might also be a good starting point to discuss how to better synchronize
development and documentation. There is this whole help ID business (we can
assign an help ID to various parts of the GUI and when these have focus and
one hit F1 for instance, or when hitting the Help button on some dialog, it
brings you to the corresponding manual page/section) also which I think
would be worth being disentangled. How should devs choose the IDs? How
should documenters be made aware of new IDs? I think some process and more
communication would definitely be worth it.

Now Damned Lies has been updated appropriately and the master branch is
properly processed again.
Thanks to all who helped!

So I proceeded with the branching which was planned. As of today,
`gimp-help-2-10` is the branch to continue working on GIMP 2.10 series
documentation. `master` is now dedicated to GIMP 2.99/3.0 so we can start
documenting new unreleased features.
I opened a bug report to Damned Lies to ask for this new branch to also be
followed by the translation infrastructure:
https://gitlab.gnome.org/Infrastructure/damned-lies/-/issues/239

Last point: it has been 10 days since I proposed for Jacob to be
co-maintainer on gimp-help repo. We got agreement from Mitch and Marco and
none speaking against, so I proceeded with this. Jacob is now considered a
new co-maintainer of gimp-help!
Welcome Jacob to your new role on this repository (or as you said yourself
on IRC: maybe you are doomed now! 😛).

For the record, we merged the Python 3 port today. So gimp-help is now at
least a bit less outdated! 🤣

Damned Lies broke on POT generation for this module though, because of
missing dependencies (cf.
https://gitlab.gnome.org/Infrastructure/damned-lies/-/issues/236) but I
guess it should be fixed soon.

By the way, I would like to propose for Jacob Boerema to be promoted as
co-maintainer on the gimp-help repository, since I believe he is now the
one who knows the best its technical logics, scripts and alike among still
active contributors (actually even considering activity on gimp-help in the
last 10 years, he did the most in the last few weeks). For the record,
Jacob has been a very active GIMP contributor for a year now, and he is
doing excellent technical work.
I believe the gimp-help repository can only benefit from having someone
technical-side among its co-maintainers.

Thus is there any of the current maintainers against adding Jacob as a new
co-maintainer? I'll take an absence of answer as being OK with it, but if
you read and are in favor, I will appreciate even a short answer. 😉
If none is against it, I propose we add him on the maintainers list in a
week or so.

By the way, if anyone wants to update some data in the list, please tell me
(if you don't want to be considered a maintainer anymore for instance
because you went to do something else and have no time anymore for
gimp-help; or if you just want to update your email address, etc.). At
least one person in the current list has an email address which doesn't
work anymore.
For current info, see:
https://gitlab.gnome.org/GNOME/gimp-help/-/blob/master/gimp-help.doap

Cool. Maybe we'll hold off the branching a day or 2 to first resolve the
Damned Lies issues and if we find any more little details to fix before
branching.

Thanks! I was not really thinking none was reading so I didn't mind too
much the absence of responses (especially as here I don't think there is
anything controversial, but who knows…), but I still needed to make the
announcement, just to (1) make sure we are not missing anything with our
change and (2) because we don't want anyone to be left out of important
decisions.

Anyway thanks for the answer! 😉

Jehan

P.S.: Marco, sorry, I realize you were in the main recipient list of my
previous email. You were supposed to be in BCC, along with other
maintainers of the gimp-help repository. Anyway, not that your email is not
known here 😉, but I know many people don't like to be direct recipients of
emails.

[Jehan Pagès via gimp-developer-list]

Hi all, developers, documenters and co-maintainers of the gimp-help
repository,

This is just a small reminder for our plan to merge the Python 3 port (by
Jacob Boerema) and do the gimp-help-2-10/master branching this week-end,
i.e. in 2 or 3 days unless outstanding issues appear. If anyone has a
reluctance, this is the time to make it heard.

Otherwise, my next and last message on the topic will likely be once we
have done the merge and branching!
Have fun and thanks everyone! 🙂

[Gimp-developer] Notice to documentation contributors: plans to update the gimp-help repository

[Jehan Pagès via gimp-developer-list]

Hello all!

Some efforts is being made to improve a bit the documentation process:

1. A Python 3 port is being worked on right now by Jacob Boerema (see
https://gitlab.gnome.org/GNOME/gimp-help/-/merge_requests/50). He nearly
finished. I don't think anyone is against this since Python 2 is EOL, but
if anyone has any comment, please feel free. Also Jacob has some issues
with the `xml_helper.py` script so we wondered if this one was actually
being used by anyone actually contributing to the documentation (because if
not, and it is not considered useful anymore, maybe some time can be saved
by dropping this script).
In any case, feel free to test the associated branch and make any remark.

2. We are considering branching the tree (to `gimp-help-2-10`) so that the
`master` branch will be used for preparing the documentation specific to
GIMP 3, whereas any work specific to the 2.10.x series can continue on the
new branch.

We feel like these 3 plans could be done in about 2 weeks (so let's say the
weekend of June 5/6), but if anyone feels like this is wrong, or that
things should be done differently, please tell us before we merge the
Python 3 port and branch the `master` tree, please.

Róman Joost, Ulf-D. Ehlert, Marco Ciampa, Julien Hardelin, Michael Natterer
and Michael Schumacher (all in BCC) in particular, you are the
co-maintainers of this repository (if the `MAINTAINERS` and .doap files are
still up-to-date), so we'd appreciate your input in particular. Any other
contributor is welcome to give an opinion too of course. We don't want to
do any mistake. 🙂

The third plan we have (not within a 2-week schedule, but hopefully at
least before GIMP 3 release) is that we wonder if a better process for
releases of the documentation (on the website in particular) could not be
done. Maybe we are wrong, but it feels like the release/update into the
wild could be improved, couldn't it?
What we are thinking are things like tagging the tree leading to automatic
(or at least easier) build then publication of the documentation online,
probably through the Continuous Integration pipelines (we have been
improving GIMP release the same way lately, by generating source tarballs
automatically, and these days, we are doing the same with the Windows
installer).

So same here, if anyone has any opinion or wishes on how the documentation
process should be improved, we welcome the ideas and propositions.

Thanks all!

Jehan, on behalf of the GIMP team

[Gimp-developer] ANNOUNCE: GIMP 2.99.6 released

[Jehan Pagès via gimp-developer-list]

Hello everyone!

We have not been very good with announcing releases on the mailing list
lately, so let's fix this! In particular, we have never announced here any
of the development releases of the 2.99 series (the unstable versions meant
to become GIMP 3 later on) even though this is actually the third one!

* GIMP 2.99.2 (2020-11-06):
https://www.gimp.org/news/2020/11/06/gimp-2-99-2-released/
* GIMP 2.99.4 (2020-12-25):
https://www.gimp.org/news/2020/12/25/gimp-2-99-4-released/
* GIMP 2.99.6 (today):
https://www.gimp.org/news/2021/05/08/gimp-2-99-6-released/

Note about the release dates: some people may have noticed that versions
are tagged earlier in the git repository, because we now wait for at least
the Windows installer or macOS DMG before announcing a new version, and for
mirrors to sync up. In GIMP 2.99.6 case, we are even 11 days late, but such
is life! It is nicer not to announce something most people cannot test.
Though our flatpak (Linux) package is always timely distributed a few hours
after version tagging.

For a list of the changes, with nice text and screenshots, please refer to
the relevant news link above, on our website. For a more complete list of
changes since GIMP 2.99.6, please see the "Changes" section below.

Happy GIMPing,

Jehan and the GIMP team!

 gimp-2.99.6.tar.bz2

Overview of Changes from GIMP 2.99.4 to GIMP 2.99.6
===

Core:

  - Various fixes for Wayland support.
  - Canvas Size dialog now displays a template selector to simply
resize the canvas to a known template. When the image's and
template's pixel density don't match, a choice will be proposed to
set the image's PPI to the template's one or to scale the template's
pixel size with the image's pixel density.
  - Off-canvas guides are now allowed. Guides are not deleted anymore
when dropped off-canvas, but when dropped off-viewport.
  - Pinch gesture is now possible on canvas for zooming in/out (works on
Wayland, not on X11; untested yet on *BSD, macOS, Windows and
others).
  - GimpAction core class now stores a reason for explaining being
disabled. This can be used later for giving better hints on why some
effects or plug-ins are not usable in some situations. We already
had this feature, but by tweaking the action's tooltip, which
prevented this to have proper styling on GUIs and disrupted action
search (as the reason text was searched, hence may return actions it
should not).
  - Copy|Cut-Paste could already operate on multiple layers, by merging
the result into a single layer. It will still do this when a
selection exists, yet will paste layers as-is otherwise. This makes
an alternative way to move layers, which is sometimes easier than
drag'n dropping (especially between separate images).

Tools:

  - Paint Select tool got various improvements:
* apply a threshold on the image mask before triggering the
  automatic expansion to simplify mask handling in the gegl
  paint-select operation.
* enable viewport-based local selection.
  - GEGL Operation tool is now moved into Filters > Generic menu because
it behaves more like a generic filter conceptually. As other
filters, the GEGL Operation action is now only active when there are
opened images.

API:

  - The generate "Metadata" frame layout in a GimpSaveProcedureDialog
has been improved to always show the same number of columns to avoid
ugly layout with options on 3 columns, then 2 columns on the next
line (for instance).
  - The "Reset" button in GimpProcedureDialog shows a down arrow to show
this is actually a button menu.
  - "Save|Load Defaults" in GimpProcedureDialog are renamed as "Save
Settings" and "Load Saved Settings". The term "defaults" was not
very clear and could be confused with "factory defaults". Moreover
tooltips were added and the "Load Defaults" button is now only
sensitive if "Save Defaults" buttion has been hit at least once.
  - Annotations improved.
  - Drop g_object_notify() in favor of g_object_notify_by_pspec() in
various implementations to avoid a slight performance hit because of
a global lock.
  - New function gimp_parasite_get_data() replacing gimp_parasite_data()
and gimp_parasite_data_size() in a GObject Introspection friendly
way.
  - gimp_procedure_dialog_new() now allows a NULL title if a menu label
was set on the GimpProcedure with gimp_procedure_set_menu_label().
  - gimp_progress_

The build scripts are readable at these 2 repositories:
https://gitlab.gnome.org/Infrastructure/gimp-macos-build
https://gitlab.gnome.org/samm-git/gtk-osx/

Builds happen automatically on Circle-CI servers (with public logs for
everyone to review). The process is explained in the gimp-macos-build
repository.

Current maintainers for the macOS build are Oleksii Samorukov (who created
the process but lacks time lately) and more recently Des McGuinness.

So I would suggest to first have a look at the scripts. Then you are
welcome to propose some patches to work on a build for the dev version too,
which would indeed be very nice. I'm not 100% sure, but I don't think that
Des has had the time to look into it as he focused on getting the stable
version up to speed first. Anyway more devs the merrier.

Something which can be done is to set up a branch for you and we will let
you merge test commits on this branch for you to get acquainted with the
build system and have automatic CI builds (while not merging tests into the
main branch). If you are interested, please tell me (on a report or on IRC
for instance).

It's true there is Arabic translation, but according to the stats, far from
complete (68% on stable branch and 47% on dev branch). Anyway we always
welcome more contributors. 🙂

Basically translations are handled by the GNOME localization teams and you
have to contact directly your locale team to participate. For Arabic in
particular, here are the contact information:
https://l10n.gnome.org/teams/ar/

Have a good morning/day/evening, and hoping to see your new translations
soon! 🙂

So it feels like you are saying goodbye.
If so I hope it's only a temporary one and you'd be back if we get more
active on the color management side. We will, we definitely will, because
it's a major part of what GIMP 3 is supposed to be about anyway.

I personally have a high theoretical interest on this topic, but not a
practical one unfortunately (because we work in sRGB), which is why it is
both high in priority for me (because we need it for GIMP 3) and low
(compared to what we actually do day to day with GIMP). I have always been
hoping that Mitch and Ell would be back soon as they are much better suited
than me to decide on these topics anyway IMO. These are actually very
intimidating topics. I do understand them (or so I believe), when

Just for the record, there are no such versions: 2.99 and 3.1. Or to be
accurate, these are dev versions, they don't "count". Whatever is in 2.99
and whatever will be in 3.1 doesn't matter but for testing. We don't mind
too much broken stuff in these (we obviously prefer non-broken stuff, but
this won't stop us from releasing something for people to test the rest,
i.e. what is not broken).

As for API in particular, it means that API compatibility is a non-existent
concept there. We are heavily testing. The API may end up broken even
between 2 micro releases (like 2.99.4 to 2.99.6). This is what these
versions are for. What matters is only that we get the right API for GIMP
3.0.

That allows users time to adjust their scripts.
>

It had been decided long ago that the API could break for our GIMP 3.0
release. I mean, the multi-layer related functions you give are only the
tip of the iceberg. There are so many more changed functions, and in
particular all the base API for plug-ins are changed anyway. Now the old
base API don't even exist anymore. So anyway all plug-ins will have to be
updated. It's not even an "if" anymore, and it's not even related to
multi-layer selection (even without this, all plug-ins will have to be
updated).

I mean, it's already too late. We have not just started or anything. This
work on base API changes started more than 2 years ago (after we released
GIMP 2.10.0) and reverting this (losing 2+ years of work by several people
and using probably just as much to bring compatibility back) is not an
option as far as I'm concerned!

Which is also why we have started to talk about this long before, made news
about this on GIMP website and we started to release dev versions. The
current dev API is unstable (as already said), but it's still close to what
will be released as stable. So plug-in developers are very welcome to start
porting. Whatever will change between now and finale stable GIMP 3.0 likely
won't be as much as what already changed between 2.10 and current dev
version.

We also plan to document the main changes, with porting docs, tutorial and
whatnot.
And also we hope to have the new extension platform by the time we release
GIMP 3, to help people port their plug-ins and upload them.

In the end, the change won't be so complicated. It may look scary, but in
the end, I don't think even the most complicated plug-ins will need much
more than 30 min to be ported. Ok maybe 1hour if rlly you made a
hugely complicated plug-in, I don't know. Talking from experience of having
participated to port many of our core plug-ins.

Are you talking about third-party scripts or the ones we provide? If the
core ones, of course we should port them before release. But not providing
a compatibility layer again. As said, GIMP 3 is our chance to improve our
API, 25 years of cruft, 25 years of evolution, new features, new usages, so
many things different. The goal is not to continue with double the mess.
Like if we talk about multi-layer related API, what? Do we want to propose
every layer API in double now? Both multi and single layer? Then do the
same when we finally make vectors and channels multi-selectable?

I'm not saying what you say is wrong. Of course, in an ideal setup, we try
to never break any past API. But in this ideal setup, we are more than a
handful of contributors. Right now, trying to do what you propose would be
like releasing GIMP 3.0 in 5 years. I don't think anyone wants this.

So yeah this is why we just decided long ago that API breakage was allowed
as it was a major version update. We don't do useless API breakage, but for
stuff like multi-layer selection, this just makes sense. It will be a new
ability of GIMP 3. Nobody wants our API not to be able to access this
feature. And we don't want to maintain double the functions.

Yes. It's one of the many issues we currently have with the meson build.

Which is why the meson build is absolutely not replacing the autotools one
so far. We still officially ask people to use autotools (in the context of
a final build, like packaging; developers who want to contribute are
obviously welcome to use meson so that they can contribute to fix the
build).

It is far from being the only issue:

Re: [Gimp-developer] where can I see this string in action (translation related)

If not mistaken, these are labels shown on an intermediate export dialog
(back from a day where export had a 3-dialog workflow: choose path, then
this dialog, then the format options dialog; now it has a 2-dialog
workflow). This intermediate dialog is not shown anymore (now the export
code automatically does what it says here, which is not a problem as it
doesn't actually modify the image but a copy of it), but the code is still
there in our codebase lurking (this change is before my time, so before
2012, I don't know when exactly).

Someday we might want to do something about it (anyway I have big plans for
the export process, though I'm not sure when I'll get there). In the
meantime, I'd suggest to just translate to what it seems to mean, it won't
matter much anyway as none will see it. So don't bother too much.

Jehan

P.S.: there is actually an environment variable you can set to force the
intermediate dialog to appear. I can look it up if ever you really want to
see the strings on GUI.

Actually Wormnest (our current Windows dev boss!) says he builds from MSYS2
from Windows. The ones who cross-build from Linux are the Linux devs (like
myself!) who can't bother to set up a full development environment on
Windows. 😛

So yeah it should work with both methods.
Though building GIMP 2.10 natively from Windows is apparently a real pain
(because autotools are very slow natively on Windows), but master branch
with meson should be much easier. At least that's what I hear.

Yes, the best is really if you find yourself issues you had with GIMP and
try to fix them. All current long-term GIMP developers started like this.
We encountered a bug and dealt with it. It can be something very basic. It
is much more enjoyable when you actually work for yourself than just for
the sake of it. 🙂

Also I would suggest to come and discuss on IRC (#gimp on irc.gimp.org).
This makes things more enjoyable for you than just dropping patches (at
least I think, personally).

May I ask about your usage of GIMP in Texas A&M University? This is

Unless mistaken, we don't have this string in GIMP itself. As this is part
of the list of devices, I think it is returned by one of the other layers
of the system. I have not investigated much to see which layer it is, but
this is this one which should return localized strings if adequate.

Indeed. They were actually translatable/translated, but only when shown
alone (in the "Axes" list). I have made these to be also translated when
used in the  "%s Curve" and "The axis '%s' has no curve" context.

Thanks for noticing.
If I may, next time though, I'd suggest to open a bug report:
https://gitlab.gnome.org/GNOME/gimp/-/issues

Otherwise your reports might end up forgotten if we don't process them
immediately (for this one, we got lucky).
Thanks again.

Yes, as you say, it's a joke with the GEGL mascot being a goat. The name is
indeed not very relevant. This plug-in being now in a "development > Goat
exercises" subsection and the new dialog clearly saying that it is a
demo/exercise plug-in for plug-in developer is the relevant part. In the
future version, there should not be any ambiguosity anymore of what these
are, even with the funny name.

Now it's not saying that you are still right that the ambiguosity
definitely remains on GIMP 2.10.x, but then it's only about time management
(and the limits of this time), and this is the only reason why I won't even
look at it in GIMP 2.10, but also why I would still accept patches if
someones wishes to do so.

Ahah well, I guess both the goat and its friend (rather than owner!) are

Joke aside, if I recall, it's just a color invert effect. Not much interest
other than showing how to make plug-ins and how to call GEGL operations
from GIMP plug-in code.

On the master code (future GIMP 3), I made quite some change to the Goat
exercise.

First of all, there are now several goat exercises, one for each binding
which we tested, i.e. so far a C one, a Python, Javascript, Lua and
probably soon a Vala one. Also they are in a menu section called
"Development".

And most importantly, when they run, they don't directly run a GEGL
operation, they first open a dialog with a header label explaining that the
plug-in is a demo demonstrating how to make plug-ins. Under the header
text, there is a text box displaying their own code, and at the top there
are 3 bouttons: Cancel, Source and OK. "OK" runs the filter operation and
"Source" sends to the last version of the plug-in source online (in the
repository).

Basically in the future, this plug-in will be a looot more interesting,
self-explanatory and better labelled.

Right now it makes no sense when translating in any language, except if

Are you asking this as one of the translators of GIMP?

Including for GIMP 2.10.x...
>

Now I agree that the plug-in is not self-explanatory enough in GIMP 2.10.x
and I understand that people will wonder what this filter is exactly.
Personally I know I don't really want to spend much more time in the
gimp-2-10 series. This is passed, it has been like this for 2 years
already, nobody ever complains of it (and if they don't get it, a simple
web search or asking on a forum like in your link and they can get their
answer), so I think my time much better used to make it better for the
future GIMP 3.

Yet if anyone were to propose some patch to goat invasion, possibly to make
it work the same on GIMP 2.10.x as it does now on master (it's not just a
simple cherry-pick as we changed the API, but it should not be too hard
anyway), I would gladly accept the patch.

I was clearly annoyed, if not indeed a bit offended by the answer (what and
how you said it was not very pleasant, if you read it with a neutral mind,
you should see it), though I was still calm and thought I stayed diplomatic
in my answer. Sorry if this part didn't get through, always hard by writing.

So yeah, no problem, don't worry. I am not angry or anything here. :-)

Yeah we have some team roadmap of things we generically think should go in
this or that version. And there are global dev efforts in these direction
(like GTK+3, non-destructive editing and such). But mostly development is
driven by individual priorities, objectives or even sometimes just "where
they have most fun", on a finer level.

I re-read my email. Nowhere do I say such thing. I consider this project to
be one of my main priorities (I'd say it's easy in the top 10 of the

I'm sorry, we don't do dates. We don't do rough estimates either.

Things will be done when it's ready, that's it. I haven't taken the time to
work on this particular feature the last few months as I was doing other
stuff. I will continue implementing the feature. I can't tell when this
will happen and when this will be finished. I don't know either.

Re: [Gimp-developer] Python2.7 reaches end of life

[Jehan Pagès via gimp-developer-list]

Hi all!

> Since Python 2.7 reaches end of life (in a week), what is the roadmap  of
switching to Python3?

We are already using Python3 on master, as Elad said. Don't expect anything
to happen for the GIMP 2.10.x branch (which will continue to use Python 2,
even though deprecated, and so be it). Not because we don't want it, but
because we don't have the people to work on this. Also we can't just
invalidate all existing Python 2 plug-ins.

> As far as I understand, Jehan is coordinating it.

Just to make things clear, I coordinate as far as I was the only one
working on Python 3 port, and I am the one who initially ported libgimp* to
GObject Introspection. But I am happy if anyone decides to go all the way
out and take some responsibilities. ;-)

> I also understand that mitch created new methods for plugins for UI, and
I am not sure whether I am supposed to use them or not.

You are welcome to use any existing API. Or propose improvements and
patches if you feel it's not quite right yet. Until GIMP 3 is released,
even can change. I would even say that everything *should* change now if it
has to (after release, it will be too late as we will have to keep
compatibility for years to come).

> Personally, I am a bit stuck on creating UI for the plugins.

There is also the possibility to just create GUI the GTK+ way, manually by
calls to Gtk.* functions, widgets creation and whatnot. This is what C
plug-ins do. No reason we don't do it for Python ones too until we get
proper GUI generation.

Alternatively, you may already start porting partially the plug-ins,
without the GUI part for now and we can work on adding the GUI later, on a
second step. Iterative port is better than no port at all.

In any case, thanks for helping Elad. This is useful. I will look at your
patches and review at some point. Don't worry. :-)

Helmut, if you wish to join the fun, we'd be happy! :-)

Jehan

I have never been but we might go some day. Not sure if this will happen
the coming year though. So far LGM is the only public event we really try
to be at every year (unless some thing were to occur, but personally I
managed for the last 6 years).

See you hopefully at one of these events!

After Alexandre told me why he was asking if we go to FOSDEM though, I'd
like to note that, even though we were not planning to be there, I'm not
against coming for the weekend if there is any funding (accomodation + trip
Paris-Brussel).

Though when I read what you are looking for (technical talks for game
creation), it's close but not exactly our expertise. On our side, we make
animation films (https://film.zemarmot.net/
https://www.instagram.com/zemarmot/ to get an idea, we did this too:
https://framatube.org/videos/watch/9c9de5e8-0a1e-484a-b099-e80766180a6d ),
also 2D rather than 3D mostly.

Also is it *developers* oriented? Because I'm not sure what would interest
you which targets developers. Now maybe we could talk about animating or
something if it's not only for developers?

I don't know, reading your email and your CFP, I am just a bit unclear if
we can be a fit there since it seems a lot about talking about one's
experience about making games. And well… we don't have any (except for
minor hacks for fun years ago, maybe, but I would not call this experience!
Ahah) so not sure that's what you are looking for. 🙂

Or maybe we could just do some round table to discuss what people are
looking for in a 2D image creation tool for game making.

Apart from this, yeah we love hearing that you like using GIMP for game
creation and we'd love to talk about your usage. And indeed discuss about
how we can make things nicer both for you and us.

I have been working on better extension management in GIMP, and when I read
about asset workflow/integration, I wonder if this cannot go within the
same plans. Well this would need to be discussed to know exactly what you
are looking for, I guess!

However, we are up for a meeting in late May during Libre Graphics
> Meeting, in Rennes, France:

Indeed we should be in LGM, as every year, so this can be a good
opportunity to meet as well.

As for FOSDEM, I am not against, but as said above, we need
trip/accomodation paid for at least, and discussing also what kind of talks
you want (we would not want to be a disappointment or look like a mismatch).

That's it. Have a good weekend and tell us what you think.
Have fun!

Is it a question because it is actually going to be impossible to have
pygtk in some distributions in a close future?
If so, which distribution, and for when?

Yeah Python has always been an option but it is also a very important
feature of GIMP. People will not be happy if their scripts suddenly stop
working.

This being said, we already dropped pygtk in the master branch (future Gimp
3), which now uses GObject Introspection for Python support (both 2 and 3)
and much more (we tested with success already JavaScript and Lua too, and
someone is working on Vala if not mistaken).

Now when will GIMP 3 be released? Nobody can say. We'd really like GIMP
2.10 to keep Python 2 support for as long as possible.

Re: [Gimp-developer] Forwarding bugfix release request we received on GNOME board list

[Jehan Pagès via gimp-developer-list]

Hello Philip,

We are in contact with this person (since this team does indeed the Marathi
translation, and I even helped them to get started as there was no active
Marathi coordinator so their initial contributions were stuck) and were
even aware of this specific request for a release (dating from January as
your email shows).

Back in January, I told Dr. Snehalata Shirude that we were hoping to do a
release soon, which unfortunately didn't happen in the end for various
reasons. We are still planning a release very very soon, though I cannot
say an exact date (same as I couldn't back then).

In any case, I am sorry to tell we cannot answer to requests for release.
It's done when it's done. Such is the saying. :-)

I am the first to hope we could have even more releases (though I don't
think we are too bad with 5 release since last April). Yet things are so
that we don't have the resources, neither have we the intention to speed up
things just because a university (or anyone/anything) uses GIMP, even
though it is very cool. I'm sure you understand as I doubt that GNOME would
speed up its release as well if it were to receive the same request, right?
:-)

Still thanks for relaying.
Have a good Sunday!

I guess it may makes sense to save this option so that the checkbox stays
checked if we left it checked last we used a filter. On the other hand, I
could imagine it to be annoying sometimes, especially if you fail to notice
it to be on (in case of subtle changes). :-/

I understand the issue. This is annoying sometimes when I turn on a feature
with guides and they are invisible. Unfortunately making them always
visible is definitely not an option. Guides are very practical feature but
they are also in the way. Many often, you absolutely need to make them
disappear. This is just as true for generic guides, as for mirror guides,
or here split view guides. In the later case, the guide is just right in
the border between with and without the effect you are comparing. Sometimes
you want to do so the most seamlessly possible. And a line just at the
separation points is making the comparison difficult.

If you have a lot of need to switch guide visibility on/off, I'd suggest
you change the shortcut to some direct key. I know this is what does the
artist I work with, because guide visibility is quite a frequently used
switch.

Re: [Gimp-developer] Spyrogimp plugin rewrite

[Jehan Pagès via gimp-developer-list]

P.S.: As you can guess, I never took the time to actually look into
re-implementing the clone as an available tool in your plug-in. That was a
cool feature, but I don't think if I will make the time to add it (as I
don't need it other than it's cool :P). So feel free to just add it back if
ever you manage to fix the issue previously raised. :-)

Re: [Gimp-developer] Spyrogimp plugin rewrite

[Jehan Pagès via gimp-developer-list]

Hi Elad,

Sorry for the delay before inclusion. I must admit I completely forgot
(just while doing something else tonight, I suddenly remembered this
proposal for an updated Spyrogimp!).

So I took some time tonight to review again, then finally pushed your
plug-in.
I just did some trailing whitespace cleaning, and also simply renamed it to
"plug-in-spyrogimp", basically dropping the "Plus" part. I understand that
the "plus" was about saying it is another more advanced plug-in, but I
prefer to think of it as just a new version of the same plug-in (even
though a total rewrite), so that we can later on just drop the old version
(maybe when moving to GIMP 3?). When this happens, if there is only one
plug-in and it is named "plus", it makes not much sense. I guess. :-)

Anyway here is the commit for the initial code you provided, as-is:
https://gitlab.gnome.org/GNOME/gimp/commit/a702c6a3270485e1320521c89499e1b3270477d4
And here my commit with the slight changes:
https://gitlab.gnome.org/GNOME/gimp/commit/e91028df2f9669fe2d98f05a969692695a62003f

I hope you will stay around for any fixes which might be needed later on.

Do you have a GNOME gitlab account?

We are definitely interested by any AI algorithms. At least I am.

The hard point here is "if someone can commit to […]". It's a bit hard to
commit without knowing much (unless you are paid, then you have no choice
;p). Usually it's the other way around: you propose something. It doesn't
have to be with a great GUI or whatever. Then if we like what we see, we
will definitely add our own 2 cents to the pool. This is usually how most
features are done around here, when someone contributes a patch with a very
cool idea, then we review and often fix/change what we think is needed
(sometimes just a bit, sometimes deeply).

I often wrote crap GUI myself and others came to the rescue with ideas and
code. :-)

I would suggest to *not do that*. :-)
Basically we are not a company, we don't sell GIMP and don't have huge
plans for the next decade. Well "officially", we do have a roadmap and
such, but if you follow GIMP development, you'd see it is more flexible and
experimental than some rigid plan.
Making a huge list with big plans for the future "might" be just the way to
spend a lot of time and kill your project in the end.

Instead I would propose **you** just select **one** such algorithm which
you find is great and even irrefusable since it would be so fucking awesome
and useful! Then you implement and propose it and we will be so amazed that
we just have to include it and do a proper GUI for it. That sounds like the
best plan.

From there, you can go on with more awesome ideas. :-)
You may even be able to start doing more organized work with a list of
algorithms after, etc. But for a first patch, I would suggest you just take
the lead.

There is only a single very important part about AI algorithms which need
training: we will want the code to train, the data, etc. everything as free
software/Open Data and properly documented.
I have worked with trained algorithms in Free Software where the trained
data is just dropped as-is, and once the original author disappears, this
is unmaintainable. In particular it cannot be improved or fixed or nothing,
because we don't have the code to re-generate the neural networks (or
alike). This can only be a recipe for failure long-term.

So AI in GIMP? Yeah definitely! But it has to be reproducible generated
data, with the whole training infrastructure available and properly
documented and the input data under Libre license as well.

Cool. Depending on the idea, it may be interesting to rather implement it
directly as a GEGL operation (GEGL is our graphics engine). Maybe you don't
even need to make a GUI then. Just make a GEGL op, and when it is done, run
it with examples to show us how good it is, and we might just get into the
game to make it a proper GUI.

And here you are! I hope we will see soon a lot of baby robots in our code.

Yes, but in order to distribute them, we will have to set up  build servers
(for various platforms) because our upstream repository server won't just
distribute third-party built binaries without any security nor review.
Though we will be able to add some exceptions for some plug-ins with safe
sources, such as G'Mic, created by a well known public research facility.

It will support dependency to GIMP versions (for instance if it requires an
API released in a given GIMP version) and to other extensions (an extension
can depend on another extension). I have not planned any other kind of
dependency so far.

Yes sorry. My answer was definitely a bit annoyed, I should not have
written it this way.
It's just that we get this question once every few months (maybe more, I
don't follow all discussions/ML much) and regular requests to change to
this or that language (whatever is the current fashion, javascript, python,
rust…). It's just a bit annoying. Also the time I wrote this answer (10PM)
probably did not help.

But in any case, I should not have written away any frustration to you. So,
sorry again for this.
As you say, yeah the shorter answer is "it's historical".
Let's keep it at it and pretend I have not written the previous answer. ;-)
Thanks!

I am not going to change the appdata format. If you absolutely wish to go
this way, you can contribute to the format specification (they are hosted
at freedesktop), though to be fair, I doubt they are going to change it (it
has been used for years now, and is widely spread on Linux distributions:
basically all software management is based on this nowadays), nor do I see

For the same reason I am not going to change the appdata format: when you
contribute to a software, you don't try to change all its basics. And GIMP
is indeed written in C. This has been so for 23 years now. I don't see why
it is complex by the way. I have programmed in a lot of languages (many
script languages as well, I even maintain some software mostly made in
Python, etc.) and I find C just fine.

I am not interested in discussing a port of GIMP to some language X, if not
for the first reason that the work required to do such port would just
block us for years (and you would not see GIMP 3 for like 10 years?!
Neither the extension manager as well of course, since we'd have no time to
implement it anymore, nor any of the cool new features we are bringing in
nowadays).

Now I am happy to be wrong, and if someone were to port the GUI part of
GIMP into some well maintained and interesting/powerful/simple language,
making any graphics change easier, without any regression or feature loss,
if this person contributes us a working patch tomorrow, I test it, it just
works and keeps all the "promises", then I'd be the first to consider the
patch for inclusion (though I would not be the only one to decide). But
other than this, please don't ask us to do some work which we find not
useful. I have a lot of things where I want to see GIMP improve (see my
signature; we are making an animation film, as a professional studio, and
my main worry is not the language of GIMP but what it can do and how, and
if it is stable/fast) and spending years to change our base language is
certainly not one of these.
Sorry. :-)

Well yeah, code is in master (for some times now). There is no
search/installation part yet, but the core code: basically what is an
extension (the metadata format to describe the contents (both with
Human-text description and for automatic consumption), the loading of
extensions, enabling/disabling them, etc.
Please read:
https://girinstud.io/news/2018/07/crowdfunding-for-extension-management-in-gimp-and-other-improvements/
And you can refer to commits done after this too.

Note that it won't work on Windows yet (as I saw that's the OS you are
interested in), because the library used for metadata parsing is not ported
to Windows yet (on my TODO list).

So I finally reviewed.

* The background color of self.pattern_notebook is always white, which is
especially a problem with darker themes. Is it only for me? Don't you have
this issue too? I had a look and am unsure where this comes from though
(maybe it's a problem in the theme, but I have no idea).

* I had once a warning about broken undo when setting "Clone" (then I had a
warning about no clone source, but this one is normal) then canceling with
Esc.

Apart from these, it looks good here. :-)

Re: [Gimp-developer] Spyrogimp plugin rewrite

Hi Elad,

I've had my mind elsewhere so haven't reviewed yet, but noticed a new GEGL
operation named "spyrograph" was added with your authorship. Does it do
everything your new plug-in does?

I guess it is probably not worth including the new plug-in if it makes it
to GEGL as a new operation instead. :-)

For the record, I saw the email and will review (and merge if no problems)
your code. I have had not much time this week, but hopefully it will be
better next week.
For git authorship, do you confirm I should use the name and email as used
on this mailing list?

As for the GEGL operation discussion, I definitely see how cool it would be.
But if you say it would remove some features, of course we could discuss
how to make the best out of both worlds. I don't know enough about this
plug-in yet to be 100% relevant though. :-)

You are more than welcome to contribute to the manual too. The source is

Same as we welcome patches for GIMP, we also do welcome patches for the

Also at some point, we should resume discussing making your package
upstream. It's hard to make time to discuss this, but this is probably
needed. Moreover lately the maintainer of the Snap package approached us to
make it upstream as well. So I thought this is the opportunity to discuss
about AppImage as well.

That's a cool update, and we could replace the old spyro by the new one (or
on 2.10 at least deprecate the old one and hide it from menus but leave it
alongside for the PDB API).
I wonder if this could not be a GEGL operation also by the way, rather than
a plug-in.

Feedback is welcome.

[Gimp-developer] Packagers: core plug-ins will be installed in subdirs in GIMP 2.10.6

[Jehan Pagès via gimp-developer-list]

Hi all!

That's a message mostly for packagers (it doesn't matter for other people):
the core plug-ins will now be installed in sub-directories. I.e. the
plug-in `file-webp.exe` (on Windows) will be installed under
`plug-ins/file-webp/file-webp.exe`.

The `make install` step takes care of everything, but this info may matter
for update process (depending on how you do it), as you might want to
delete `plug-ins/file-webp.exe` (and other plug-ins directly under
`plug-ins/` in previous versions of GIMP).

This is one more step towards getting fully rid of DLL hell.

This doesn't change anything for third-party plug-ins which can still be
installed directly under the user config's `plug-ins/` directory though we
advise against it. We advise to install user plug-ins under subdirectories
as well.

RPM libs and tools are available on most (if not all) distributions that I
know of, even when based on other package systems (like .deb packages). :-)
This being said, in appstream-glib, RPM support is an option. I'm not sure
what it is used for, but I doubt we use anything related to this in GIMP.
You should not try to make featureful builds of dependencies at the first
attempt.


> What is appstream-glib and how is it going to be used in GIMP?

This is a lib to process the AppStream metadata format. This is used for
the new extension management system. I don't think that anyone will be ok
to have builds without this feature, when it will be released, considering
how important it will be, hence that's not an option. :-)

Note that I use the future because even though current dev code use this
already, this will show its importance in more code to come. But it still
has to be non-optional dep because we are no going to make our lives more
difficult just for the sake of it.

I remind (just in case!) that master code is for development. It is
certainly not advised for daily use, in particular. And we are not going to
develop with outdated versions of libraries for instance (unless you want
to see features be released with completely outdated code). So yes, we use
recent versions (while still being reasonnable, hence the famous "at least
available in Debian Testing" rule). A developer is expected to run such a
modern OS for developer, not a LTS or other old distributions for "stable"
systems.

Then there is the question of Windows or macOS. We hope we can help these
libraries to become cross-platform soon (same as we helped libmypaint to be
easily cross-compiled, as well as GExiv2, and many others… wasn't there
libheif also recently?). That's what we do all the time. And hopefully this
will happen again.
Now I am not saying it is impossible that we ever get back and use
something else if it turns out really too complicated a task. But we need
to at least try and go this way first. I currently see no reasons why it
would turn out impossible to improve the library to be more cross-platform,
as we did it for many others. That's what development is for.

For the record, I just checked current code and actual minimum dep
(relatively to the functions I use from this lib) would be 0.6.7.
I could set a lower value, but really the development is barely started on
this feature, I will use more API soon so it may go back up soon anyway,
and I'm not sure if it is worth just going back and forth on dependency
versions.

Note that I originally chose this version 0.7.7 by looking at Debian
Testing, which is our base for deciding whether a version can a requirement
in the development GIMP.
Also this is development code. It is expected to get bumpy. We even
realized this dependency has problems to build on Windows, but it's ok. We
are confident that this will improve. This is not the first time (and won't
be the last) that we improve projects by using them, and in particular that
we make them going cross-platform. :-)

Maybe. As I said, I was only extrapolating from a single discussion on some
"social network".
In any case, the macOS backend may be there, but in a poor state
apparently, since I believe that a discussion between several contributors
of GTK+ (one of them being still a very regular contributor, and another
being the maintainer!) is definitely more trustworthy than whatever press.
:-)

I have no idea. Has it been removed? Is it still here but just completely
broken and waiting to be fixed?
Or simply so untested that none really knows?

For information, I am referring to this discussion:
https://twitter.com/acruiz/status/998552715654463489
As you can see, the first message is:

Don't take my word for it. I was just relaying what I understood from the
Twitter thread above, which may itself not be perfectly informed.
It seems clear that the macOS backend is not that maintained though, seeing
how various GTK+ devs are clearly stating this as a fact, but I actually
guess they would not just remove years of code just on a whim (I hope so).

There is another issue which was raised these days by GTK+ developers who
discussed GIMP port: apparently GTK+3.99 (to become GTK+4) has currently no
macOS backend! Basically that means we'd lose GIMP on macOS. And worse,
they have (nearly or none at all?) no developers working on this, so it's
not even sure when or if it will come.

Actually even GTK+3 macOS port is bad but at least there is something. The
Windows backend on GTK+3 is bad too (still according to GTK+ devs) but is
more tested than Windows backend.

So yeah thinking about porting to GTK+4 is far too early. And anyway we
have already far enough to do. Deciding to port to a moving target (i.e.
unstable API) would be just masochistic.

I think that is definitely a good point, and I am in favor of creating as
much high level "semantic" API as possible (when it makes sense). This
would create some boiler plate intermediate code, but is definitely worth
it on the long run IMO.

Just to be clear, the toolkit update here is not *just* a necessary evil.
It will also be totally awesome, even feature-wise! Without doing much, the
differences are already dramatically awesome IMO, like the simple fact that
input devices (read: graphics tablet) don't have to be activated manually,
nor plugged before running GIMP (hotplug support), etc.
Then we'll be able to add touch support (zoom, pan, rotation of canvas with
fingers).
And much more. This is very exciting.
In any case, the benefits are definitely not "iffy".

Simply to get there, we have to pass through an "unstable" phase, that's
all there is to it. The old master (which became 2.10) has had this phase
too, I can definitely tell so. When I started contributed, back in 2012, it
was absolutely unusable for daily use as well (though you say you were
already using the master build daily back in 2013, but maybe you are less
demanding as us :P). Not only unstable, but also slow as hell. Absolutely
impossible to use for painting.
This is just how software development works.
:-)

I did more updates to the docs. For the record, I *think* the docs is now
up-to-date with all new changes in the XCF format.
If anyone thinks some stuff are still wrong in the docs, please feel free
to open bug reports (rather than emails which I may miss) explaining the
parts where things are still unclear or not right when compared to actual
XCF files.

Indeed, the XCF doc has not been much updated these last year.

I have just now updated a bit the docs for:
- zlib compression (which is now a possible internal tile compression);
- new layer modes;
- update in the header with the "precision" field.

See the recent log commits:
https://git.gnome.org/browse/gimp/log/devel-docs/xcf.txt

There is at least one more update relative to group mask. I will do this
tomorrow.
There are also some changes relative to endianness, but I'll have to dig
deeper (it looks like it was only a bug which would have touched some
development XCF format only).

I will complete the docs with these 2 more information tomorrow. Now I'll
go to bed!

[Gimp-developer] Master branch string freeze until Sunday 20th of May

[Jehan Pagès]

Hello everyone!

We are going to release GIMP 2.10.2 with many bug fixes and even a few new
features on the (hopeful) date of 2018/05/20.

Therefore I am announcing a string freeze on the master branch until this
date.

This means that we ask all developers to not add or modify any string on
master until the release of GIMP 2.10.2 is effective. If you have a pending
patch with string changes, please do not push it and wait a few days. You
will be able to push it after we announced the release.

Announcement on the gnome-i18n mailing list:
https://mail.gnome.org/archives/gnome-i18n/2018-May/msg00031.html

Thank you everyone!

Jehan

Which is normal, since it is GEGL 0.4, not 0.3. ;-)

And yes, you are right. The GEGL dependency in libmypaint is GEGL v0.3, and
I am not sure that will change soon, since libmypaint developers are mostly
working on libmypaint v2 now. You can still ask them if they would make a
libmypaint v1 with updated GEGL dep.

BUT for the time being, it is not much a problem because (1) GEGL v0.3 and
v0.4 can be installed next to each other (hence the different namespace)
and (2) you don't have to build libmypaint with GEGL. libmypaint-gegl is
not used by GIMP in any way to this day.
So just build libmypaint with --disable-gegl and don't care about
installing GEGL v0.3.

Re: [Gimp-developer] GSoC project query

[Jehan Pagès]

Hi!

For the record, our would-be intern had a job proposal, and therefore had
to cancel his GSoC proposition. He even asked me if that is OK, and
obviously I told him to do what's best for him!

Anyway this was quite interesting to see a bit the possibilities for GSoC.
Maybe next year, we'll try "for real", telling people beforehand we wish to
participate, etc. If once again I am the only available mentor, I might
once more integrate into another project, like GNU.

Also for anyone disappointed, I would like to reassure you: if there is one
thing that should be learned from past GSoC participation of GIMP, it is
that GSoC is far from the best way to improve a software. Personally I am
mostly interested in it because it is nice to help some students discover
real development world and mentor them. And maybe these students will even
stay regular contributors *afterwards*! If we can get a few cool patches in
the process, this is cool. But this event should not be considered as a
cheap way to get code. Any project which relies mostly on this to improve
will mostly get hardly maintainable code.

When I see how some people seem to see GSoC as a miraculous event which we
should absolutely join, I am a bit dubious on how you envision this event.
Whatever your job is, picture yourself when you were student. Now imagine
that you suddenly dropped your student self into your current position
which you are in after years of hard work and learning the job though
actual real-life projects, successes and failures. Do you really believe
that your student self would have just revolutionnized your current job in
just a few months? I hope you don't say yes, because that would be a bit
sad if you don't believe you evolved since you were students! ;p

In the end, whatever the regular developers do in the same time as any
intern is 100 times more important, and I remind that some of us (including
myself) are even trying to make a living from GIMP development through
crowdfunding with quite weak success for now. Just a small reminder so that
people know they can crowdfund us (in case of my own project, all links in
my signature) which will be more efficient for any of the goals you
proposed in this thread or others than what GSoC could bring us (even if
still a cool event, but for helping good students mostly, as I said, not
for magically cheap, fast and quality code).

Have fun everyone!

Jehan

I just wanted to add that Kris is the person who makes things happen in
GIMP for macOS. As far as I am concerned, as said earlier, he is therefore
the one who should call the shots regarding such macOS build questions,
rather than a vote (unless he wants to decide through a vote himself)
because in the end, he is the one who has to make the grunt work here (as a
volunteer, I remind).

For the record, I did try to get in touch with Apple some time ago (may
have been a year ago, or more, or less, I don't remember), and I didn't get
any answer.
Or maybe I had an answer to a first email who told me to send an email to
another address, but I didn't get an answer from this second contact. Or
something like that, I can't remember exactly.

Bottom line: they don't care, and they didn't answer.

I feel that anyone who believes that Apple would even care about us is
misled. What are we compared to Apple? Nothing. Seriously what is the PR
for them here?
Now I'm happy to be wrong. Maybe I wrote to the wrong contacts (I don't
know anyone from the "inside", and simply tried to get through the official
contact media). Maybe they would sponsor. Maybe they would even donate more
as João believes possible. I don't believe so, but I may just be
pessimistic.

As for answering, I think I will just vote "I don't care".

But really for me, this is hiding the real issue: we have barely no macOS
developers. We have mostly a single dev caring for macOS, but his time is
very limited (which is not a problem, everyone has one's priority and he
does already a lot). For instance, 10 days ago, I made some changes to
macOS code, hoping for a macOS developer or one of third party packagers to
test the change. Nothing happened until today, just before the release (as
expected, things needed to be fixed).
So it looks a bit funny to me to be discussing how to better package for an
OS when we have nearly none to improve things for this said OS.

What I would love is for people who wants GIMP on macOS to actually *care*
for their OS (not "care" by *saying* "I care" but by actual action, i.e.
the real meaning of "caring"). If we had a few developers fixing regularly
GIMP for macOS, improving things, etc. then these people would want to get
a proper signed package for this platform, I'd be happy for us to have an
official account, even if I completely agree with Mitch that it is really
garbage that we have to pay for real good and clean Free Software; this is
shameful from this company. Yet if we have actual people giving of their
time, and really showing their care, I'd still say It would make sense.

But right now, we are discussing paying to distribute a version of GIMP
which is barely kept alive. This is a bit doing things in the wrong order
IMO.

Jehan

P.S.: most of what I said can be said for the Windows build too. Well
actually we seem to have slightly more love for this build, yet barely.
Only GIMP on GNU/Linux (and *BSD seems to have people watching closely too)
is actually very well maintained with a huge flow of fixes and improvements.

This is typically the kind of projects which are both "easy"
technically, but actually difficult to do right. Because it is not
only about stacking up various brushes which look cool and have as
many as possible in GIMP (especially in current situation where brush
management is so shitty that it is not a good idea to have too many).

We are discussing the topic with Aryeom and Americo and this is quite
harder than I thought it would be (I am the one who originally
proposed Americo to work on it).

So I definitely don't want to give this to a student. We will stick to
working with the artists who use them.

Interesting. Since everything is 32-bit internally already, will it
contribute to make painting faster as well?

If you want to contribute ideas, you can add them to the wiki:
https://wiki.gimp.org/wiki/Hacking:GSoC/2018/Ideas
Please if you do so, if you could add some explanatory links too, that
would be awesome, because I would not be able to implement several of
your propositions without some serious reading myself.

Remember that this is for a student. The main reason why GIMP stopped
doing GSoC is because we were giving the students very awesome
projects, and even though the final results were very cool
proof-of-concepts (so the students did do very good work), they were
not finished (either extremely buggy, with bad standard code, or so
slow that it was unusable on real data, etc.) and they had been a dead
weight to the GIMP project for years (even nowadays, some older
student projects are still making issues).

Well that is from a time where I barely started contributing myself,
so I am just telling what I gathered, and basically I want to try and
take into account the "elder's" experience (old farts! ;p) to really
get something good out of such a project. That may mean less ambitious
ideas (which does not mean they are not just as important for GIMP!).

For the record, GNU accepted our request, and invited me as a mentor.
So I am now subscribed as a GSoC mentor for GNU.
This does not gives us automatically a slot. I assume in the end, the
choice will depend on how many slots are given to GNU. We'll see.

Since there is a slight overlap in the schedule of the current FSF
internship and GSoC, I asked the FSF contacts if that would be a
problem. Since having Darshan as a GSoC student would be beneficial to
both GIMP (longer contribution from Darshan) and Darshan himself, they
said that would not be a problem to wrap up the FSF internship earlier
if our project got accepted for GSoC.

Now we have to decide of a good project for GIMP/Darshan since GSoC
needs us to decide this first. Note that, as already said previously,
I am more in favor of feasible and more concrete projects for GIMP,
even though maybe less fancy looking that what we used to have for
GSoC. Something which will definitely end up in GIMP in the end. :-)

As Prokoudine said, we have not any plan doing this yet, but I would
not be against. You should ask people at GNU if they would accept to
give us a slot. They are the only one who would be able to tell you if
it is ok.

Indeed. The first 'G' already means "GNU". You were basically

It is better to read the INSTALL file when you are building a software. :-)
Or in the case of GIMP, If you build from git repository, then read
INSTALL.in instead. Everything is explained.

As you note yourself, libmypaint do not contain MyPaint brushes, which
is a problem. This is why mypaint-brushes is a separate package. It is
available in https://github.com/Jehan/mypaint-brushes
Install the branch v1.3.x and make sure that your PKG_CONFIG_PATH is
well set (once again, everything is explained in details in
INSTALL.in).

> I have the appropriate RPM installed, and the brushes are located at
> "/usr/share/mypaint/brushes" but GIMP does not see them...

Yes these are installed with MyPaint, but this is a problem because:

(1) it makes MyPaint a defacto dependency to GIMP since we use
libmypaint (which is useless without brushes).
(2) there is no way to know where the brushes are but guessing. This
is what we were doing previously trying various common places (/usr,
/usr/local, etc.). But this is not an acceptable solution. We need to
know where each of our dependencies are actually installed with
certainty.

This is why we have a separate package which hopefully will be used
also soon by every project using libmypaint out there (instead of
duplicating these data everywhere! For instance, I read that it is
what OpenToonz is doing: they just ship MyPaint brushes which is not a
good idea).

That's interesting. How does the FSF internship work exactly? Does it
require GIMP to assign any mentor too or are you mentored solely
within the FSF?

The mailing list drops every attachment, so we didn't receive it.

Well there are many topics of interest. What are you the most
interested by? There are lower level work on graphics algorithm and
stuff, in which case, that would be rather work on GEGL. If you want
to work on GIMP itself, I wrote for instance a few quick ideas the
other day (when we considered participating to gsoc with GNOME, though
I'm not sure this will happen):
https://wiki.gimp.org/wiki/Hacking:GSoC/2018/Ideas

Someone else (right now on a discussion in IRC; I think he said he
sent an answer too but I don't see it) was interested in someone
working on our API using GObject Introspection to allow more language
support. Why not.

These ideas are obviously not exhaustive. If you have yourself other
topics which interest you, we can discuss.
Only thing is that we prefer small yet solid work which can be merged
at the end of your internship rather than an awesome yet very
complicated feature "on-paper", which only ends as a demo in the end
and is never finished by anyone.
We have had some mitigated gsoc experience and some code from gsoc
students are still rotting around after several years.

Anyway yes, we are interested. :-)
We can continue discussing here, you can also drop on IRC (#gimp at
irc.gimp.org), and we can also discuss privately if needed be.

A bit of git log searching gives the response to this:

Bug 763214 - Wrong rendering of shadings in PDF imports...

Require libpoppler >= 0.44.0 which contains a fix for this bug.

Note that git *master* is not supposed to follow whatever is in the
stable distributions. We may have some advance, which is normal for a
development version. If ever we limited ourselves to what is in any
distribution *currently*, then *that* would be the start for problems.

In any case, as a general rule, it is better to have state-of-the art
versions of everything since they are supposed to get better (but for
exception and regression bugs).

Yeah as the git message says, that's not a change of API or anything.
So it would work. But then you may encounter bugs in rendering of
shadings. Or not. We don't take the chance. :-)

Well there is nothing in the command line itself which relates to
libexiv2. It looks like there is something wrong in the libtool script
wrapper generated by the build system. Delete the file "libtool" which
you will find in the root of the git repository. Then run the
configure script again (this will create again the libtool wrapper),
then make and let's see what happens.

Well I'm lost. Are you sure you did a build from a fresh start? No
files at all from a previous build?
You can run `git clean -dfx` to erase every file from the repository
which are not in git (be careful not to run it carelessly and erase
important personal files!).

Other than this, I really have no idea with only this.
But if you still have the error, please run `make V=1`. This will make
the build verbose and tell exactly which command was run. But first,
you should make sure you did a fresh build, really from scratch.

Both seem fine. pkg-config does not seem to detect any exiv2 in /usr/local/.
Are the build still broken and outputting the same errors?

Were you building inside the git repository or in a separate
directory? In the second case, make sure the build directory is empty.
Could you send us the contents of "config.log"? Since gexiv2 and exiv2
are looked up with pkg-config, it will allow us to see what was
detected too.

Since you can't attach a file, just copy-paste its contents somewhere,
for instance at https://paste.gnome.org/
Thanks!

Yeah autogen.sh does not have to run configure and MyPaint people
removed this behavior from the autotools setup I initially did. Since
I expect this repository to be taken care of later on by the MyPaint
team, I did the autogen.sh the way they like it, i.e. not running
configure. :-)

Jehan

P.S.: also I don't really like that the autogen.sh run configure
myself. It can sometimes be a bother when you want to do VPATH builds
but the autogen script often wants to be run from within the source
root. Anyway…

Yep that's on purpose. MyPaint/libmypaint development evolved their
brush format with incompatible changes. There are new parameters (some
of which can currently crash GIMP, which is still to be fixed on
libmypaint side) and some parameters are the same but actually behave
differently.

The library has been versionned already (current libmypaint master is
version 2 though there has been no release yet) and we needed to also
have brushes versionned as well for the above reasons. We also needed
brushes as a separate package (otherwise MyPaint is a dependency of
GIMP!) and finally we needed to make sure of the installation path
(otherwise we have to "guess" and in many cases, the MyPaint tool was
just useless with no brushes available).

For all these reasons, I took the MyPaint current brushes. And I made
a branch to freeze the brushes before all the changes happened. But
the master branch still needs to follow MyPaint master development.

Indeed!
I'm not sure why everyone was only adding a lib/pkgconfig/ but
share/pkgconfig/ is also to be added in any custom prefix in
PKG_CONFIG_PATH!
Why it worked inside /usr is because this is already in the defaults
path of pkg-config for the /usr/ or /usr/local/ prefixes but you have
to take care of it for any custom prefix.

Also why can it be in share/ or in lib/? The logic is quite simple: if
this is a library, the pc file goes in lib/pkgconfig/, if this is a
data package, it goes in share/pkgconfig/.
Have fun!

No linguistic reason, no. Just I haven't thought better.
We still need to have a longer message in the tooltip so that we can
have a better understand of the action because the name is just a
color (which is pretty not descriptive), and even more because there
are several similar actions (set layer color tag, set channel color
tag…). And the similarity of the message helps to associate them as
similar actions, especially in some out-of-menu context (i.e. the
action search) where just reading "Red" would be a pretty
non-descriptive information on an action.

But it's true that ideally we could/should factorize the strings to
not repeat the same text base.

This would indeed be better, indeed.
Now there is a technical difficulty. These strings are not in a
printf-style gettext call. They are in an initialization array for
action entries with a given non-printf format. We could theoretically
change the struct GimpEnumActionEntry to allow for some
printf-formatted string, and consequently change as well the function
gimp_action_group_add_enum_actions().
Of course if we did this, we should do the same to other
Gimp*ActionEntry (and association add_*_actions() functions) to be
consistent.

Basically I feel that would be a lot of boring work for limited
advantage IMO. :-/

I believe --g-fatal-warnings is generated by glib whereas
--gtk-g-fatal-warnings is generated by GTK+. Probably even just a
wrapper of the former.
Though I may be wrong. I don't think I ever searched this specifically.

Yeah if you can't grep it, it may just be some CLI option generation.
I am not sure. :-)

Both exist and work. Run a `gimp-2.9 --help-all` to see them. :-)
I believe they are synonyms though clearly using the version without
"gtk-" in it is 4-letters faster, hence more efficient (I don't know
why I always use the option with gtk- though).

But yeah, both exist. ;-)

The command is:
$ gimp-2.9 --gtk-g-fatal-warnings

GIMP will crash as soon as it gets any warning.

To run this into gdb, you run first:
$ gdb gimp-2.9
Then inside gdb prompt:
(gdb) run --gtk-g-fatal-warnings

Well maybe you are not using cage transform tool correctly. Yet even
though no critical warnings are meant to happen! That is a definite
bug.
Also even if you were not using it correctly, then it would mean there
may be a design flaw. Cage tool should not be that complicated to
operate.

Yep. Warp is cool indeed. :-)

Well if it doesn't work and if there is a GEGL-critical, yes there is
definitely a bug. ;-)
You should run gimp with --gtk-g-fatal-warnings to force it to crash
when it gets a warning. Doing this inside gdb will get you a
stacktrace which led to this warning so that you can copy-paste it in
a bug report. :-)

No. The symmetries work for paint tools (children of GimpPaintTool
class), but the warp transform is not a paint tool (I mean, not in our
code; it is derived directly from GimpDrawTool, which is lower level
class).
Of course, in theory, that could be changed. But this is not how it is
implemented currently.

Cool. That's old style how it would have been done with paint tools as
well. I guess this still has to be done for other tools until someone
make symmetries even more generic.
