A minimal project manager for the terminal.

This script must be sourced, not run in a subshell. See usage for more information.

At present, prm supports zsh, as well as bash. For more information, see the Wiki page on Zsh support.

Regrettably, fish is not supported because of syntax incompatibilities. See this issue for some details. However, Fred Deschenes has made a port for fish that you could check out.

This program basically lets you CRUD projects. Upon activation, each projects runs its associated start-script; on deactivation, it runs the project stop-script.

These bash-scripts can be used for things like changing directories, setting environment variables, cleanup, etc.

There is basic prompt integration in the form of [PROJECT] <prompt>, which can be seen in the animated .gif demo above.

You can have several projects active at once in different shells, as prm associates active instances with the shell PID. Currently active projects can be listed (as described in usage).

Dead project instances (i.e. project instances that are still active on shell exit) will be automatically deactivated the next time you run prm – without running their stop-scripts.

Adding and editing projects will open the associated start- and stop-scripts in your editor (as defined by the $EDITOR environment variable).

A project start-script might for instance look something like this:

# cd to project directory
cd $HOME/src/Python/hello-world

# activate conda env
source activate hello-world

# show current git status
git status

The same project's stop-script might look like this:

# deactivate conda env
source deactivate hello-world

# clean up
rm *.log *.tmp

When you activate a new project, prm automatically stops any active project in the current shell.

When a project is deactivated, prm changes the working directory back to the path you were originally on before starting your first project.

If you often create projects similar to one you already have, you can load custom scripts from your projects' start.sh and stop.sh. For instance, if you'd like some python-based projects to list the number of outdated packages in their conda envs, you can save

# count outdated packages in conda env
echo "$((($(conda search --outdated --names-only | wc -l)-1))) outdated packages in env"

as e.g. conda-list-outdated.sh in $PRM_PATH/.common/ (this environment variable is detailed in usage). You can then load this script in your start- and stop-scripts like so:

prm_load conda-list-outdated

Additionally, if you need the name of the currently active project, this is available via the $PRM_ACTIVE_PROJECT environment variable.

Command line arguments are available in scripts, with $3 being the first argument after your project name.

I found myself missing project management features (like those seen in text editors and IDEs) on the terminal.

Instead of remembering what projects I am working on these days or switching between loads of terminal windows or tabs, I now use prm.

In order to work properly, prm must be sourced, not run in a subshell; i.e. . ./prm.

The easiest way to do this is probably to add an alias to prm in your ~/.bashrc (or wherever you keep your aliases), like so:

alias prm=". path/to/prm.sh"

From the help option screen:

usage: prm <option> [<args>] ...

Options:
  active                   List active project instances.
  add <project name>       Add project(s).
  copy <old> <new>         Copy project.
  edit <project name>      Edit project(s).
  list                     List all projects.
  remove <project name>    Remove project(s).
  rename <old> <new>       Rename project.
  start <project name>     Start project.
  stop                     Stop active project.
  -h --help                Display this information.
  -v --version             Display version info.

You can set the prm data directory with the $PRM_PATH environment variable. By default all prm data is written to ~/.prm.

Feedback is strongly encouraged. If you run into a bug or would like to see a new feature, please open a new issue. In the case of bugs, please mention what shell they occur under (i.e. bash or zsh).

Contributions in the form of code (e.g. implementing new features, bug-fixes) are also appreciated. For information about this, see the Wiki page on Contributing.
