[gentoo-dev] Last standing Python 2.7 dependency

[gentoo-dev] Last standing Python 2.7 dependency

Hi all,

I've cleared my system from Python 2.7 almost entirely, with the sole
exception being dev-lang/python-exec, which relies on a hack to absorb all
possible Python versions in python-utils-r1.eclass. Shouldn't python2_7 be
removed from _PYTHON_ALL_IMPLS there?

python-exec does not depend on the Python interpreter, so you can
depclean it.

Hi all,

I'd also like to clean my system and have it Python 2.7 free. Are there any
guidelines to check which packages are still using pyton2_7 in my system?

Thanks,
Viktar

There are both equery and enalyze commands in gentoolkit that can give
you reports about what pkgs are installed.

equery hasuse
enalyze analyze [use|pkguse]

for help on them:
equery -h
equery hasuse -h
enalyze -h
enalyze a -h

In addition to these great tools, portage-utils' quse might also be
useful:

% quse python2_7
...


Thanks,

All of the mentioned tools will show if packages have the flag but not
necessarily have it active.

eix has an option to search the active flag:

eix --installed-with-use <flag>

However, this still skips build-time dependencies that may keep python
2.7 around.

The most accurate way to see what's tied to python 2.7 is to pretend to
remove it:
emerge -pvc dev-lang/python:2.7

Not True:  

enalyze does strictly installed pkgs analysis, plus has the
ability to rebuild package.accept_keywords and package.use files after
profile changes or disaster (file loss, etc)
