[issue29326] Blank lines in ._pth file are not ignored
Vladimir Chebotarev added the comment: Hi. I guess this issue has to be reopen because Alexey erroneously broke adding empty paths to `sys.path` along with his patch. Official embeddable Pythons do contain a blank line in its ._pth, and this allowed users to import modules from script directory.

[issue29326] Blank lines in ._pth file are not ignored
Vladimir Chebotarev added the comment: Hi Steve. I'll try to explain what is my motivation. I need a reliable way to run Python (not matter embedded or not) in isolated mode, but still having current directory in `sys.path` (empty entry). Ironically I could misuse normal mode to simulate isolated mode with specified %PYTHONPATH% (which is not much handy, by the way), but hiding Windows Registry keys would look pretty hard (it is impossible to make a bat/cmd wrapper). Possibility to search %PYTHONPATH% in HKLM entries makes it even worse. Empty entry in `sys.path` is a extremely popular thing, and many software depend on it. It looks like a bug that isolated mode cannot support such entry. # How would I fix it. Possibly we should allow another keyword for adding an empty entry (like we have an exclusion for `import site`). Ideas are appreciated. -- ___ Python tracker <https://bugs.python.org/issue29326> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue33698] `._pth` does not allow to populate `sys.path` with empty entry
Vladimir Chebotarev added the comment: Unfortunately this is not true: "Blank lines and lines beginning with # are skipped." (https://docs.python.org/3/library/site.html#index-1) I'm not sure we should change this behavior as it would make huge impact on usage of `pth` files by users (`._pth`, on the contrary, is the only one per distribution and managed by the distribution). I could easily add `''` to `sys.path` manually if I had one script or even dozen of them, but as the solution that alternative is not acceptable. :( -- ___ Python tracker <https://bugs.python.org/issue33698> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
