[19:23] <dialtone> hpk: hi!
[19:23] <dialtone> when are you coming to italy then?
[19:23] <hpk> i am trying to convert the py lib to use nicer/saner names for getpymodule()'s
[19:23] <hpk> dialtone: not sure yet
[19:24] <hpk> dialtone: as soon as i know i contact you
[19:24] <dialtone> cool ok :)
[19:24] <hpk> thanks for your mail :-)

[19:29] <arigo> hi!
----- silence for 17 minutes ----- [19:46] <arigo> stakkars: about generating short local names:
[19:46] <arigo> the feature is more generally useful
[19:46] <arigo> e.g. when we show the graphs in pygame
[19:47] <arigo> maybe this code of yours could be moved outside the code generators,
[19:47] <arigo> where it would really rename the Variable objects
[19:47] <pedronis> arigo: hi
[19:48] <arigo> hi!
[19:49] <pedronis> did you see my checkins
[19:52] <arigo> not yet
[19:53] <arigo> I'm fiddling with UNDEFINED_CONSTANT
[19:53] <arigo> I tried to make it clean in the flow space,
[19:53] <arigo> using the Atom class instead of UndefinedConstant subclass of Constant
[19:54] <pedronis> I see
[19:55] <pedronis> I worked on making contains precise
[19:55] <pedronis> if we simply ingnore revisions as we did
[19:55] <pedronis> the annotation can get stuck
[19:56] <pedronis> it happened with translate_pypy0
[19:56] <pedronis> I wrote a test
[19:56] <pedronis> and now it passes
[20:02] <stakkars> arigo: yes (about short local names)
[20:02] <stakkars> right now, I'm rewriting it and putting in into gensupp.py
[20:02] <stakkars> The problem is that it is quite more complicated than I thought.
[20:02] <stakkars> I will try to finish it and use it, then we can move it away, after some cleanup.
[20:03] <stakkars> The messy thing for a general solution is:
[20:03] <stakkars> I want it to always work,also if we re-order code blocks afterwards.
[20:04] <stakkars> That means, I have special rules about name scoping.
[20:04] <stakkars> No global name may ever shadow a local one, *and* vice versa.
[20:04] <stakkars> For nested scopes (which might come, soon), the name reusal rule is:
[20:04] <stakkars> A name can only be reused on the same scope level if not in the same function.
[20:06] <stakkars> there comes quite some smoke from my brain to get this allright...
[20:07] <stakkars> summary: I'm trying to make sure that nothing ever shadows anything, regardless how we re-order.
[20:07] <arigo> quite complicated indeed...
[20:07] <arigo> but not what I suggested above
[20:08] <arigo> which was to rename the variables in the flow graph, simply
[20:08] <arigo> however I understand you're trying to do much better
[20:09] <stakkars> I hope so. The problem with flow graph renaming (which is helpful, too) is that we need protection against
[20:09] <stakkars> reserved names as well. Furthermore, the flow graph cannot know the options of the generators, easily.
[20:09] <stakkars> I am decorating names when they are wrapped, genc does not, etc.
[20:10] <arigo> I should still mention that this feature doesn't look very important to me :-)
[20:10] <stakkars> I'm wasting time...
[20:10] <arigo> not necessarily, but I'd rather push you to first do the caching mecanism
[20:10] <arigo> and remove the generated stuff from svn
[20:11] <arigo> and then don't look at the generated stuff too closely any more :-)
[20:11] <stakkars> ok. My main reason was to get generated code that produces useful diff files.
[20:12] <stakkars> on renaming on the graph level: Would it be simpler, I mean, how to avoid name clashes?
[20:15] <arigo> on the graph level, I just thought about simplifying names but still ensuring with a simple rule that there is no clash,
[20:15] <arigo> e.g. prefixing all names with "l_" would do just fine
[20:15] <arigo> or "v_"
[20:15] <arigo> i.e. not trying too hard to produce exactly the correct name, because it really doesn't matter
[20:16] Action: arigo -> dinner
[20:16] <stakkars> makes sense. Good appetite
