[issue42497] New pathlib.Path attribute
New submission from ThatXliner : Add an attribute to pathlib.Path testing if a file/directory/symlink is executable or the user has executable permissions. I've been trying to find a pythonic way for this (preferably in pathlib.Path) but all I found was trips to the shell and back. This issue proposes adding an attribute (which I haven't figured the name most would like but it would be somewhere near .can_execute or .is_exe) -- components: Library (Lib) messages: 382034 nosy: ThatXliner priority: normal severity: normal status: open title: New pathlib.Path attribute versions: Python 3.10, Python 3.9 ___ Python tracker <https://bugs.python.org/issue42497> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue42497] New pathlib.Path attribute
ThatXliner added the comment: Since pathlib.Path has module os synonyms, I think it would be reasonable to test with os.X_OK. Correct me if I'm wrong. I think most people would want to check if the current user running the script could execute something. -- type: -> enhancement ___ Python tracker <https://bugs.python.org/issue42497> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue42497] New pathlib.Path attribute
ThatXliner added the comment: Now I think of it, it would be weird to just add attributes testing for executable permissions.

[issue42497] New pathlib.Path attribute
ThatXliner added the comment: Ok, so I just made a patch implementing this using os.access. It adds the following methods to pathlib.Path - can_read= Returns True if the user can read the path - can_write = Returns True if the user can write on the path - can_execute = Returns True if the user can execute the path These are implemented via - return os.access(str(self), os.R_OK) - return os.access(str(self), os.W_OK) - return os.access(str(self), os.X_OK) respectively. -- keywords: +patch Added file: https://bugs.python.org/file49637/implement.patch ___ Python tracker <https://bugs.python.org/issue42497> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue42017] Add new type in typing
New submission from ThatXliner :
Because there is a typing.AnyStr (which is equal to AnyStr = TypeVar("AnyStr",
str, bytes)), I think there should be a AnyNum which is equivalent to
from decimal import Decimal
from fractions import Fraction
AnyNum = TypeVar("AnyNum", int, float, complex, Decimal, Fraction)

[issue42023] Argparse: Add a "display" arg
New submission from ThatXliner :
In argparse, I've always wanted a way to make colored help text like those of
poetry and pipenv. But argparse's show help isn't well documented (Therefore, I
can't find a way to completely modify the help text), and the metavar arg isn't
really helpful. I want to do something like this:
>>> import argparse
>>> parser = argparse.ArgumentParser()
>>> parser.add_argument("foo", help="To foo a bar", display="FOO")
>>> parser.print_help()
usage: main.py [-h] foo
positional arguments:
FOO To foo a bar
optional arguments:
-h, --help show this help message and exit
>>>
That way, I can colorize the help output.

ThatXliner added the comment:
> So if you can get by with just customizing _format_action_invocation, there's
> no need for further action here.
Then maybe we could just make a new function that takes 2 arguments: Name of
another action class (or the action class itself), and a tuple of the arg names
to be displayed. It returns a new action class that contains the help text
properties of the given action class with customized displayed arg names.
Maybe like
parser.add_argument("-f", "--foo",
action=argparse.CustomArgName(action="store_true", name=("-F!!", "--FOO!"),
help="TO foo a bar"))
