[issue9621] Graphviz output for 2to3 fixer patterns
Matt Bond added the comment: Sorry for the delay in responding, and for getting this patch cleaned up and submitted. While I was going through my code to submit it, I found a couple of additional issues with it. Then I ended up becoming very busy with my grad courses. As a result, I haven't had a chance to do anything with it. Currently, my plan is to rework it over the winter break to fix the issues, make it work correctly with python 3, and remove the dependence on the external graphviz package (which should resolve the import issue as well). -- ___ Python tracker <http://bugs.python.org/issue9621> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Matt Bond added the comment: Huh. I must have diffed the wrong version of my code - how embarrassing! I'll update the attached patch later this week.

[issue9621] Graphviz output for 2to3 fixer patterns
Matt Bond added the comment: Éric, When I was working with 2to3 this summer I was running it via python3, so I think the patch should work - however, if I've submitted it to the wrong place or the wrong branch, where should I be looking at to ensure my code does work on 3.2 and is submitted to the right place? In regard to the import gvgraph, I wasn't sure what to do with it - for my distribution gvgraph wasn't available as a package, and it was only one file so I just dumped it in the same directory as the script. I'm open to suggestions as to how that import should be handled better. Alexander - I'll attach a sample image as soon as I get back to my development machine, which should be later this week. -- ___ Python tracker <http://bugs.python.org/issue9621> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue9621] Graphviz output for 2to3 fixer patterns
New submission from Matt Bond : As part of my GSoC project working on 2to3, I've created a script which will allow compiled fixer patterns to be visualized using graphviz. This would be useful for debugging and understanding exactly how patterns are matched. I've written using the 2to3 sandbox as my base. The script is named pat2dot and is found in the scripts directory. The script currently relies on an external graphviz library (I provided bindings for the GvGen library with this patch), they are separated enough from the rest of the code that it would be trivial to create a class that would work using a different graphviz library. Additionally, since the code is never called within 2to3 proper, this dependency will only appear if you wish to use pat2dot, and will not affect any other usages of lib2to3. Usage of the script is `python pat2dot.py fixername` where fixername is any fixer provided in 2to3, as named by 2to3's -l option. -- components: 2to3 (2.x to 3.0 conversion tool) files: 2to3-graph.diff keywords: patch messages: 114049 nosy: facundobatista, gmattbond, loewis priority: normal severity: normal status: open title: Graphviz output for 2to3 fixer patterns versions: Python 2.6 Added file: http://bugs.python.org/file18544/2to3-graph.diff ___ Python tracker <http://bugs.python.org/issue9621> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
