Set virtualenv for python in textmate 2

Question

I'd like to work in my virtualenv from textmate 2, but i really have no idea on how to indicate text mate the env of python it has to use.

If anyone can help, thank you.

Answer 1

You will probably need to use a wrapper script, to first activate the virtualenv and then (within virtualenv) start the textmate2 process.

wrapper example:

#!/bin/sh

# load the virtual env
. $HOME/MY-VENV/bin/activate

# run the editor
/path/to/textmate "$@"

Answer 2

If there's a project folder associated with your virtualenv, you could add a .tm_properties file that contains something like

TM_PYTHON = "$HOME/.virtualenvs/example/bin/python"

In fact, I might make a project template for virtualenvwrapper that does just that for all new projects.

To set it globally in TextMate 2, just add TM_PYTHON to the Variables section of the preferences. You should be able to set PYTHONPATH the same way (per-project or application-wide).

Answer 3

TM_PYTHON in the TM2 preferences for environment variables determines the Python to the preferred interpreter, but I did not find out yet, how to set the PYTHONPATH for TM2 yet.

Answer 4

This article essentially shows Rob McBroom and K.-Michael Aye's answers in greater detail.

NOTE: It seems that you must disable any she-bangs (#!/usr/bin/env python in my case) for this to work.
