I run zim from the git (been doing that for years). After pulling 0.75.2, I
get load errors:

AttributeError: module 'inspect' has no attribute 'getargspec'
ERROR: Exception while loading plugin: sourceview

Did I overlook something?

Good point. AFAICS zim does not use polling or timestamps. When you open a
page it is always reloaded. When the page is (temporarily/permanently)
closed zim checks does clash detection.

This means that my current PoC already works except for clash detection.

The problem is that when the alien document changes, there is no way to
update the corresponding zim document. Both zim and the other tools are
unaware of wach other.

I now have a PoC implementation that uses additional zim headers.

Content-Type: text/x-zim-wiki
Wiki-Format: zim 0.6
Zim-Load: convert-to-zim mydocument.json
Zim-Store: convert-from-zim --output mydocument.json
Creation-Date: 2023-01-20T21:11:50+01:00

While this works nice for transparently loading/storing of alien documents
there's still one important feature missing: zim uses the timestamp of the
zim document to detect external changes and this timestamp is not updated
when external tools modify the alien document.

An alternative approach is to use a fuse filesystem that transparently
converts documents from alien to zim format and vice versa. A bit like
using a cannon to kill a gnat...

Suggestions?

Looking at the code I see that Zim uses readLines (in newfs.local) to fetch
an page. This looks a good place to intercept and silently convert
the document from alien into zim format, so that zim only sees zim
documents.

However, before a page is loaded, there is also a call to readLine but I
haven't quite found out who does the call, and why. Is it some kind of peek
at the document to see if it is a zim document?

Actually, that is not the problem. Or, shall I say, that is easy for me to
solve.

What I would like to have is a load and store hook where I can perform the
conversions. I want the file on disk to be in the 'alien' format, while zim
only 'sees' zim format.

I haven't studied the code yet, maybe you have a pointer where to look?

I did some experiments and it seems that this is not a viable approach.
One of the reasons is that Zim does not recognize wiki markup when
receiving data from the custom tool. 

For example a simple 'cat' filter, run on

aaa
bbb<- this line is bold
ccc<- this line is italic
ddd

turns the content into

aaa
**bbb**
//ccc//
ddd

which is clearly not desired.

I think what I would need is something more powerful, i.e. load/store hooks.

Thanks for the suggestion. As far as I can see this will allow installing
commands that modify (parts of) the current contents. While this could be
used for my purposes, it would require manual intervention before/after
each load/save which man quickly lead to mistakes.

Also, the physical file on disk should be in the 'alien' format since it is
used and updated by other tools as well.

[Zim-wiki] Using Zim as document editor

[Johan Vromans]

Hi all,

Best wishes for 2023!

I was wondering... Would it be possible to use Zim as an editor for
documents that are not Zim notes.

For example, when I open a particular document, instead of reading it from
disk Zim would run a plugin or an external tool to fetch the actual
contents. Likewise, when the document is saved, some other plugin/tool is
run to write the contents to disk.

Rationale is that I have quite a few markdown or json documents that I
would love to be able to maintain with a decent tool like Zim.

Re: [Zim-wiki] Zim plugins: Terminal

There seems to be something wrong with line 186.

  self.terminalview.feed_child(CLEAR_COMMAND, len(CLEAR_COMMAND))

TypeError: Vte.Terminal.feed_child() takes exactly 2 arguments (3 given)

When I remove the 2nd arg, which should be legal, it yields:

TypeError: Item 0: Must be number, not str

I can't explain...

When I uncomment the line I do indeed get the terminal window and
everything seems to function fine.

Suggestions:

- display the current path in the title (it now reads "Terminal", not very
  useful).

- a keyboard shortcut to close and (re)open the terminal window

- a keyboard shortcut to switch focus to/from the terminal window

Good job!

Sounds nice... I can enable the plugin, configure it, but I do not see a

Interesting... The fact that the author is aware of the zim-wiki format is

[Zim-wiki] Parse tree and metadata

[Johan Vromans]

When I convert (dump) the parse tree of a page with metadata:

cat page.txt | python -m zim.formats wiki > foo.xml

then the metadata comes out as a leading text paragraph, e.g.

Content-Type: text/x-zim-wiki
Wiki-Format: zim 0.6
Template: Bar


Shouldn't this be parsed, e.g.


text/x-zim-wiki
zim 0.6
Bar


or something similar?

This yields: AssertionError: Not a valid function: page.meta.get .

Besides, the reference to page.meta already gives warnings if there's no
metadata (as is the case for most of my pages).

And how is this supposed to work?

Re: [Zim-wiki] Export templates

To select the appropriate template I'd like to use a meta setting,
something similar to:

Content-Type: text/x-zim-wiki
Wiki-Format: zim 0.4
Template: foo

And in the template:

[% IF page.meta.Template == "Foo" %] ... [% END %]

Technically this works, but generates an awful amount of warnings.
I couldn't find a way to test whether a page has a meta, and whether this
meta has the key.

Did I miss a hidden equivalent to the python 'key in dict' test?
