Gets the current branch and slaps it into your bash prompt.
Right now this depends on having an active virtualenv. That's kinda not the best way to do things; if you're not working on a python git project it's pretty useless unless you're willing to create meaningless virtualenvironments for those non-python projects just to use this feature.
However, since you're explicitly mapping the relationship between a virtual environment and the git project directory, I can tell you what branch you're working on even if you're not actually in a git project directory any longer.
Copy get_current_branch somewhere on your PATH.
Copy ps1.sh somewhere on your PATH.
Copy (or append) postactivate into your .virtualenvs directory.
Copy (or append) postdeactivate into your .virtualenvs directory.
Copy sample.env into your .virtualenvs/ directory.
Rename sample.env to just .env
Update the new .env file so that ${PROJECT_DIRECTORY} points to the actual
git project directory for this virtualenv project
Update your ~/.bashrc so that the PS1 environment variable is the output of
the ps1.sh command. For example, you can add this to your ~/.bashrc file:
PS1=`ps1.sh`
Source your ~/.bashrc file
Issue a workon command to begin working on a specific virtualenv
If you've set everything up correctly, your command line should now have the git current branch for that virtual environment.
NOTE: If you're not "working on" a virtual environment, you'll see [Inactive] instead of a branch name.
- Get this to work without depending on an active virtualenv.
Possibly just degrade back to running a simple get_current_branch and if
you're in a project directory use that info.
- Related to the above, either have some setting or change the default so that your branch info is gathered only if you're in the project directory.
Right now your branch info is gathered based on the virtualenv=>git-project linkage you define. It may be that you don't want to do this but would rather have the active branch info be dependant on what git project directory you are currently inside of.
