Instructions on how to install afew with Python3.12(.3)

[xaltsc]

Hey,

As for my particular setup, I'm running Alpine with Python3.12.3. I couldn't find a way to (re)install afew as an unprivileged user.

I'm looking to install any version post the latest release, but the latest possible one would be ideal.

I essentially followed instructions here https://afew.readthedocs.io/en/latest/installation.html (with commit a3f6f6a as suggested by @GuillaumeSeren on IRC) and variations thereof, i.e.

$ python -m venv --system-site-packages .venv
$ source .venv/bin/activate
$ python setup.py install --prefix=~/.local

for which $ afew gives the following error

Traceback (most recent call last):
  File "/srv/user/.local/bin/afew", line 33, in <module>
    sys.exit(load_entry_point('afew==3.0.2.dev61+ga3f6f6a', 'console_scripts', 'afew')())

$ python -m venv  .venv
$ source .venv/bin/activate
$ pip install setuptools
$ pip install notmuch
$ python setup.py install --prefix=~/.local

for which $ afew gives the following error

During handling of the above exception, another exception occurred:

I also tried to just pipx install afew with which running $ afew gives the following error:

ImportError: cannot import name 'SafeConfigParser' from 'configparser' (/usr/lib/python3.12/configparser.py). Did you mean: 'RawConfigParser'?

pipx install --python 3.11 --fetch-missing-python afew also fails because musl.

Hey @xaltsc ,
Can you try with a newer release like 3.0.1 + python3.12 ?

I think at least some of those issue where fixed already,
also try a isolated venv without using system libs

[xaltsc]

The first two with 3.0.1 give the exact same errors.

What do you exactly mean by "an isolated venv without using system libs" ?

[hendursaga]

This looks like a duplicate of #341. See https://docs.python.org/3/whatsnew/3.12.html#configparser for why the error is shown.

[kofm]

The way I've managed to make it work is to:
a) amend the readfp method call to read_file as per the link posted by @hendursaga suggests (see above pull request).
b) also amend the notmuch-python-bindings to accomodate the changes in configparser

If you have both the amended repos on your local paths you can:

pipx install /path/to/afew
pipx inject --force afew /path/to/notmuch-python-bindings
pipx inject afew setuptools

Now should work correctly
