Re: [Pharo-dev] Pharo Papers

[denker]

Hello,

I have setup a collection at HAL. For now it is empty, we should fill it and 
then add it to the website
(and announce it then, not now…).

The collection automatically has every paper on HAL that has “PHARO” as a 
keyword in the field
"Project/Collaboration”.

https://hal.inria.fr/PHARO/
https://hal.archives-ouvertes.fr/PHARO

HAL is not Inria specific, here is some more infos (from 
https://hal.archives-ouvertes.fr ):

HAL is an open archive where authors can deposit scholarly documents 
from all academic fields.

For the attention of the authors

• The deposit must be made in agreement with the co-authors and 
in the respect for the policy of the publishers.
• The deposit is subject of a control, HAL reserves the right 
to refuse items that do not meet the criteria of the archive.
• Any deposit is definitive, no withdrawals will be made after 
the on-line posting of the publication.
• Text files in pdf format or image files are sent to CINES 
(https://www.cines.fr/en/) for long-term archiving.

For the attention of the readers

• In a context of electronic distribution, every author keep all its 
intellectual property rights.

[Pharo-dev] Build Pharo VM

[Guido Chari]

Hi,

I am trying to compile the Pharo-VM but I was not able. Neither in OSX nor
in Unix. I followed the instructions on
https://github.com/pharo-project/pharo-vm. In OSX the builder at the image
level runs ok but I see no output at the build directory. In Unix, the
files in the build directory were generated but then the building process
fails because of some cmake files not found from one of the plugins. I am
using the last version from the master repo.

So my question is, any hints on what I am doing wrong? Are there any up to
date documentation for building the vm?

Best regards,
Guido.

Re: [Pharo-dev] Any idea for a cool name for the remote tool suite?

[Ben Coman]

Not great but okay. i think we are at the point of "perfect is the enemy of
done".  There have been plenty of suitable suggestions, and its a topic
with high bike-shedding quotient, so you should just pick one you and the
man paying the bills are happy with.  Otherwise you'll get another round of
suggestions like these...
"phrem"  26k googs - pharo remote
"phremt" - 195 googs - pharo remote tools
"phremit" 225 googs - pharo remote integrated tools
"phremide" 5 googs - pharo remote ide

One thing to keep in mind though is that we can be as clever as we like
here in text, but you should imagine yourself saying it in front of a
lecture.

yes: everything :)
that instructions are very old and I still do not have time to fix them… 

basically, if all your dependencies are ok, doing this should be enough: 

$ git clone g...@github.com:pharo-project/pharo-vm.git
$ cd pharo-vm/opensmalltalk-vm/build.macos32x86/pharo.cog.spur
$ ./mvm -f

for linux you can: 

$ cd pharo-vm/opensmalltalk-vm//build.linux32x86/pharo.cog.spur/build
$ ./mvm

I fixed the oscog branch also. I could not easily test it, but it is a

so hopefully should be no problem when you next generate the plugin.

semaIndices has signalArraySize()/NSIG number of entries and is zero

beyond the  memory of the array? Can you confirm this?


restoreDefaultSignalHandlers
"Restore signal handlers to their original behaviors."

semaIndices = nil "nil if in interpreter simulation"

So it is one based but the array doesn't have an extra element to make  
it work? How is this normally handled in slang code?

Re: [Pharo-dev] [Moose-dev] How ready is Bloc for a simple use-case?

Hi aliaksei


I would love to start to play with Bloc to build a game with boxes.
Now is there any tutorial that I can follow to get started?

Hi Peter

I wanted to ask about Bloc:

Thanks for your interest :)

1) how stable is the API? e.g. if some overhaul changes to  
unify/whatever are planned


Api itself is in "final" state, however naming might be improved  
(changed with or without depreciations). But don't worry user-side api  
is already in a very good shape, at least from our >>perspective :)


2) I saw in the techtalk that you can align elements (to center,  
bottom, ...), however is that possible with lines? Lines have to  
rotate, morph shape, etc.

3) Are non-straight lines possible? (e.g. bezier, arc)
Exactly :) Lines are just bloc elements as anything else: buttons, text  
images. They can be linear, can be arcs or bezier curves (both  
quadratic or cubic). Default canvas used for rendering in >>Bloc  
(SpartaCanvas) has very good support of vector shapes and lines.



The idea for me is to make a simple mindmap

   - elements with some text, icons, math symbols inside
   - connectors (non-straight lines) between elements


It is very doable. Please, don't forget that Bloc is a low level  
framework that does not contain any widgets (existing ones will be  
deleted, especially BlLine, BlText and BlTextElement). The only  
>>responsibility Bloc has is to provide a basic infrastructure that  
does not put any constraints on users. Which means that if you want to  
have a bezier line you have to subclass BlElement, >>implement  
corresponding accessors for anchor points and override  
drawPathOnSpartaCanvas: in order to display you line. You can learn  
more about canvas by checking SpartaCanvas class >>comment and method  
comments in 'api' protocol.


Layouts, alignment, transformations are part of bloc and are available  
to all subclasses of BlElement.

Alex

Also either my (Morphic) Pharo is really slow, or Bloc (in the video)

[Pharo-dev] Raw pane on byteStrings

[stepharong]

Hi

I'm trying to debug citezen generation and I have to compare strings.
Now I think that the raw views (in Pharo 50) is not good because we cannot

See the attachements. It jumps from 21 to 174 ...
and what I want to see is of course in the middle.

Is it me or there is something wrong there.

I do not get why we doublequote the character "

Re: [Pharo-dev] Raw pane on byteStrings

[Andrei Chis]

Hi Stef,

Currently that's the default behaviour of the Raw view: it displays for
collections only the first and the last 21 elements. The Items view however
always should display all the elements of a collection.

The main problem with the Raw view in Pharo 5 is the speed. In Pharo 6 now
the speed of the Raw view is greately improved so we could increase those
limits. Still for now there should still be some limit for the Raw view.
Ideally we should add a small widget, something like a paginator, for
navigating through large and very large collections.

Cheers,
Andrei

Try doing Ctrl+P twice. It will not comment the printed string.

Re: [Pharo-dev] Raw pane on byteStrings

[stepharong]

Hi andrei

Yes. The problem is that it makes the raw view sometimes totally useless  
as in my case.

I could not see anything I was interesting in.
I found the pagniator confusing a bit because it expands in the middle (it  
means that when I want to see 54 and over then I have to scroll in the  
middle

because 50 is not a the top like in a book page.

In the toolbar menu of the stack you find 'Fuel out stack' and 'Copy to
clipboard'.
'Copy to clipboard' copies a textual description of the stack that can then
be pasted in an email.
Is this the "old textual description" or are you referring to something
else?

Re: [Pharo-dev] Raw pane on byteStrings

[Ben Coman]

A couple of random side-thoughts for Pharo 7. Would it be possible...
* to have a "diff" tab, for example to compare two strings side by side,
perhaps highlighting and being able to jump to the differences.
* to somehow reference the parent pane, for example if the current pane
shows a string element from an array, I can grab another string from the
same array to diff against
* coming at it from the other way, perhaps an array [Items] tab could be
multi-selected for elements to diff

* it would be nice if you could right-click on a tab to get a menu item to
open its implementation. Then in this case Stef might jump to the
implementation of the [Raw], change the tab's name, remove the code
skipping middle elements and in a few minutes have a new tab doing what he
wants.
* perhaps the tab menu item could be called "Customize" and it
automatically copies and renames the [Raw] tab implementation into the
String class so its ready for editing.

Re: [Pharo-dev] Why do we have doublequoting for "?

[Yuriy Tymchuk]

So if you paste this as a comment somewhere you don’t have to manually add 
double double-quotes.

I don’t use the result of print it at all, but I guess there are two scenarios 
for it’s usage. One as you described: copy the result and use it in tests or in 
some further computation. (but if you use TDD test are already written ;P). 
Another one is to copy the result and paste it somewhere as a comment in your 
code, to access it easily afterwards. If you have a double quote in your result 
it will break the comment, so the thing is escaped automatically.

Re: [Pharo-dev] Why do we have doublequoting for "?

[stepharong]

Yuriy


Why does it make sense to have "" "" inside strings?


So if you paste this as a comment somewhere you don’t have to manually  
add double double-quotes.


Did you read my example?
I do not need any double double quotes.


I don’t use the result of print it at all, but I guess there are two  
scenarios for it’s usage. One as you described: copy the result and use  
it in tests or in some further computation.


But this is exactly what I cannot do with this stupid doubling of double  
quotes



(but if you use TDD test are already written ;P).


well...

Another one is to copy the result and paste it somewhere as a comment in  
your code, to access it easily afterwards. If you have a double quote in  
your result it will break the comment, so the >thing is escaped  
automatically.


Probably but here this is inside a string.
I think that this heuristic is totally bogus.

Re: [Pharo-dev] Epicea - showing latest lost changes

Hi martin

Thanks for our constant improvement of epicea.
In VW they have a nice way to filter

you can filter the entitiies
 doit or not
 method or not
 packages or not
and you can deselect a selected item.

this way you can say I do not want any doit except this one.

Is this the "old textual description" or are you referring to something

Ok this is what I was looking for.
It looks like a generic copy past entry so I did not tried it.
Can you rename it into  copy textual stack?

Then I do not get why we could not get action about the current context  
and action about the complete stack together.

Because these are not method that we see but contexts.




   Now I wanted to report it and share with you the stack. oh  
boy!
   I thought it was file out but no it just save one method  
definition (So great)


What action did you use to file our the textual description?


fileout in the main menu when you clik on the stack element.
I never ever used it since 2006.
