AST #copy behavior
by Mark Rizun Nov. 10, 2014

Nov. 10, 2014

Hi guys! I'm using AST really often, and recently stumbled on problem with copying an AST. It doesn't copy stuff related to computing sourceInterval of AST, and I need it to copy:) I know there are #deepCopy and #veryDeepCopy, but they are too heavy methods for AST, especially in my case, as I need to copy AST all the time. Earlier, I discussed this problem with Marcus Denker. He suggested to fix #copy of AST (to be more accurate #postCopy). If I want to copy stuff related to sourceInterval, I would have to implement #postCopy for each RBNode... differently. RBProgramNode>>#postCopy super postCopy. properties := properties copy So for each RBNode... it will be like: RBNode...>>#postCopy super postCopy. "here some different code each time" I'm just interested: What do you think about it? Thanks, Mark -- View this message in context: http://forum.world.st/AST-copy-behavior-tp4789447.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Webdoc: status?
by phil＠highoctane.be Nov. 10, 2014

Nov. 10, 2014

I'd like to use WebDoc for generating my project code doc; I see that https://ci.inria.fr/pharo-contribution/job/WebDoc/ is pretty much red for a long time. Started by timer Building remotely on pharo-contribution-win7.ci.inria.fr <https://ci.inria.fr/pharo-contribution/computer/pharo-contribution-win7.ci.…> (win7 32 win) in workspace C:\builds\workspace\WebDoc Deleting project workspace... done Triggering 30,development,vm <https://ci.inria.fr/pharo-contribution/job/WebDoc/PHARO=30,VERSION=developm…>30,development,vm <https://ci.inria.fr/pharo-contribution/job/WebDoc/PHARO=30,VERSION=developm…> completed with result FAILURE Deleting matrix project workspace... Skipped based on build state FAILURE Finished: FAILURE But the green one isn't more indicative of success... What's the status? Is it used by someone? I tried the config and it crashed; github-camillobruniPPMarkdown184.... does not exit. :-( The catalog says: https://ci.inria.fr/pharo-contribution/job/PharoProjectCatalog/HTML_Report/ So, - I cloned Esteban's github repo (git(a)github.com=estebanlm/pharo-webdoc.git - git submodule init update --init Loaded by hand the packages in the submodule (petitmarkdown) Loaded the WebDoc package (the SimpleWebDoc doesn't load, even if I have Seaside in my image). In a workspace: (WebDocExporter packages: RPackageOrganizer default packages) exportTo: './doc' asFileReference. Which started to generate html files in doc/ nicely but choked while exporting FFITestLibrary Ideas why it fails? Known issue? TIA Phil

About PBE status was Re: How not to serve an AngularJs application from Pharo

I converted the first 5 chapters to Pharo 3 , 1 chapter has been ported by Stef and another from Damien, so we are more or less at 50% but I gave up as I was burned out and fed up documenting stuff :D. But (Arnold accent) I will be back ! My conversion was not flawless since this was my first project using Pillar. I think however that is ok quality. By the way I am aware of the work on the documentation for all books generally because I follow my github feed.

This a really cool idea indeed, I see now why people are excited about teapot. Excuse my ignorance about web >development but html/css and js always scared me away :D I found it a very easy way to get some existing javascript app delivered fast from Pharo. It needs a lot of refactoring and cleaning up to become maintainable though. Separate classes for the angular components, and the canvas from Seaside to structure the html. A more difficult aspect is how to create the javascript. For (qc)magritte applications it looks like a builder should be able to generate form components and a json data binding. With GT it should even be possible to integrate javascript development directly in the pharo image. And it might be better to use React or Amber or SqueakJS Stephan

I've found this problem in Pharo 3 (seems to happen in Pharo 4 too): Do: 1. Fileout Seaside-Tests-Core 2. Remove Seaside-Test-Core 3. File in the file created in step 1 You will find: a. The structure of the package changes. b. Comments for WaContextTest are lost c. You get a bunch of errors in Transcript while filing in Any ideas? Thanks in advance.

FileBrowser confusion
by Peter UhnÃ¡k Nov. 7, 2014

Nov. 7, 2014

Is anyone actually using FileBrowser? Because either no one does or I doing something wrong. My problem is that it is very uncomfortable to navigate filesystem. There is no way to quickly navigate to common folders (like roots of system drives and home directory). Also hidden files/folders are shown by default which means there is always hundred folders. I would love to have these things streamlined, ideally with the option to add custom shortcuts (see picture)... so much for opening files. As far as saving goes the only way I found to actually save file is to manually type the full path without the option to choose a folder through GUI. But since this is the way the "Save image as..." works it leads me to believe that no one is actually using it regularly, because outside of saving a file to same folder as image such behavior seems useless. So is this something that has been considered or no one really needs this? Thanks, Peter

[Oharo-users] Copy AST
by Mark Rizun Nov. 6, 2014

Nov. 6, 2014

Hi everyone, I want to get a deep copy of ast. But deepCopy doesn't work:) What I mean: | ast1 ast2 | ast1 := RBParser parseRewriteExpression: 'self'. ast2 := ast1 copy."or without copy" ast1 stop: 99. ast2 stop When evaluate this you get 99. I want it to be 4. So I want to have separate object ast2 with separate data, not depending on changes made in ast1. As I said deepCopy doesn't work. Any ideas? Thanks, Mark
