Martin Panter added the comment: Josh: Thanks for pointing out I Python. I haven’t used it much myself, but it does seem to do a similar thing to my proposal. Looks like the relevant code may be around module_completion() at <https://github.com/ipython/ipython/blob/ab929fe/IPython/core/completerlib.py#L209>.
The “sys” module is one of the builtin modules that I mentioned above. I plan to discuss changing pkgutil.iter_modules() to include it, in a separate bug report. The “os.path” case is more awkward. The “os” module is not actually a package. I believe “import os.path” only works because executing the “os” module modifies sys.modules. My code currently avoids importing non-packages, because I thought it would be annoying to accidentally run a script via tab completion (anything not protected by ‘if __name__ == "__main__" ’). On the other hand, I Python happily completes “os.path” (and many more non-submodule names). It also can be tricked into running scripts, e.g. if you do “import idlelib.__main__.” and press Tab. But maybe this is not a real problem, and I should stop being paranoid. I tend to avoid regular expressions if practical. But Serhiy you may be right that some simple string matching rules would reduce the need for tokenizing. It looks like I Python only has a few simple rules for the entire input line being “import x” and “from x import y”. The disadvantage is less accurate understanding of more complicated syntax, like “from x import y; from z import (a, bb as b, . . .”. It is a tradeoff between simpler code that only supports basic functionality versus complex code that supports more complete functionality. I hear your points about decoupling from Readline and backwards compatibility. I will consider the overall architecture more in a future update. It would be good to allow this stuff to be used in e.g. Idle (though I wouldn’t know where to wire it in myself). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue25419> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
