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.
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
. $HOME/MY-VENV/bin/activate
# run the editor
/path/to/textmate "$@"
