Hi all,
There is a recurring problem in my company where we use python in various
places (python3).
We do cross platform development windows/linux and our python scripts need to
run everywhere.
Some scripts are launched manually in a terminal.
Others are launched via windows' gui interface.
Others are launched through our build process (cmake based, but also manual
Makefile)
And others are launched via bash scripts.
And possible several other scenario I've forgot.
On windows, most users use Cygwin to do their terminal based business (`git`,
`cmake`, ...).
The issue is: There is no reliable way to launch a python script.
The command:
python myscript.py
launches python3 on windows and python2 on 99% of the unix market.
The command
python3 myscript.py
does not run on windows with the latest python distribution I've played with
(sorry if it has been fixed recently, this whole mail becomes pointless).
Human can learn which command to run, it's ok. But for all other invocations
context, this becomes very annoying. Surprisingly, `cmake` is the more
friendly, since `FindPython` will returns a python3 first.
At the moment, we have scripts that run under version 2 when run by a linux
user and version 3 on windows. This works by pure luck.
If the standard python distro would just provide a simple `python3`
binary/alias, then all the stars would align perfectly.
the basic shebang
#! /usr/bin/env python3
would work everywhere by default, without requiring any tweaking (install a
python3 alias on windows, or ask linux users to change the default `python`
symlink)
I'm sure, I'm far from being the first user complaining about that. Sorry if
the request has been been made numerous time before.
What it the status on this point ?
Thanks a lot.
Fred
