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.
$EDITORis set to a program external to Cygwin (ex: Sublime Text), you might want to add
export prm_use_cygpath=trueto your
.zshrcto send the native Windows path to the editor.
fishis not supported, because of syntax incompatibilities. See this issue for some details. However, Fred Deschenes has made a port for
fishthat 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], 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.
For the motivation behind prm, please see the Wiki page on Problem Statements and Design Goals.
Adding and editing projects will open the associated start- and stop-scripts in your editor (as defined by the
A project start-script might for instance look something like this:
# cd to project directory cd $HOME/src/Python/hello-world
activate conda env
source activate hello-world
show current git status
The same project's stop-script might look like this:
# deactivate conda env source deactivate hello-world
rm *.log *.tmp
When you activate a new project, prm automatically stops any active project in the current shell.
When a project is deactivated, prm changes the working directory back to the path you were originally on before starting your first project.
If you often create projects similar to one you already have, you can load custom scripts from your projects'
stop.sh. For instance, if you'd like some python-based projects to list the number of outdated packages in their conda envs, you can save
# count outdated packages in conda env echo "$((($(conda search --outdated --names-only | wc -l)-1))) outdated packages in env"
$PRM_DIR/.common/(this environment variable is detailed in usage). You can then load this script in your start- and stop-scripts like so:
Additionally, if you need the name of the currently active project, this is available via the
The prm command line arguments are available in start- and stop-scripts,
$3being the first argument after your project name.
All available environment variables are described on this Wiki page.
To install prm:
git clone https://github.com/EivindArvesen/prm.git, or download and extract a release .zip.
In order to work properly, prm must be sourced, not run in a subshell. 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"
The technical reason for this is succinctly explained in this Wikipedia article.
You must set your
