Specify which python version pylint should evaluate for

Question

I\'m using Sublime Text 3 With Pylinter to run pylint on my files.

However, on the same machine, I work on files for both python 2, and python 3 project

Answer 1

You can override on a per-project level in Sublime Text by changing the pylint executable setting in Project->Edit Project to include:

"settings":
{
    "SublimeLinter.linters.pylint.executable": ["py", "-3.4", "-m", "pylint"],
}

substituting 3.4 for your preferred flavour

Answer 2

You should have two pylint installations, say pylint2 and pylint3, then write a wrapper script that will subprocess the desired one.

Answer 3

This is good, but I think the simplest thing is just to use virtualenv, and install pylint in each virtualenv. The correct pylint and python interpreter will be used.

Answer 4

You can install pylint3 which will evaluate for python 3.0, and pylint which will evaluate the code as python 2.7 by default.

Answer 5

You can try python2 -m pylint ... and python3 -m pylint .... That ensures that you use the right version.

Answer 6

Expanding on @sthenault's answer and borrowing heavily from @simon's to a very similar question on askubuntu, the solution is to write a wrapper script around pylint that executes it with the appropriate version of the Python interpreter. Drop the following into a script called mypylint (or whatever) somewhere in your $PATH:

#! /usr/bin/env bash

python_interpreter="python${1}"
pylint_args="-f colorized ${@:2}"
pylint_import=$(cat << PYTHON
import sys
import pkg_resources

__requires__ = "pylint"
sys.exit(
    pkg_resources.load_entry_point("pylint", "console_scripts", "pylint")()
)
PYTHON
)

$python_interpreter -c "$pylint_import" $pylint_args

Then, execute it like so: mypylint 2|3 PYLINT_ARGS. For instance:

mypylint 2 -f colorized module.py

I'm not sure how you can tie that into sublime-text, but it more generally answers the question of parallel versions of pylint. I also bundled the above solution into a gist.
