All you need, nothing you don't.

What Does Liteprompt Do

liteprompt is a small c program to use for zsh prompts. It provides the following information:

1. updates: this is the line count for the file ~/.updates. Which can be populated by having the following cronjobs for a debian based distro:

   10 * * * * apt list --upgradable > ~/.updates 
   # and in the sudo crontab 
   15 * * * * apt update 
   

2. ssh hostname: if you are currently in an ssh session, it will print the hostname for the server
3. Virtual Env: if you have a virtual environment activated, it will display the name of the directory that holds the virtual environment.
4. Git Branch: if you are in a directory that is under git version control, it will display the name of the git branch in green if the branch is up to date, and red if the branch is not.
5. Path: The path is in a condensed form. ~/D/n/calc> would be the path for the directory /home/user/Documents/notebooks/calc.

If this is added to the root zshrc, the display will be %F{yellow}{hostname}%f:%F{red}# when the user logs in as root.

How to Install

Installation of the prompt is pretty simple.

Dependencies

The only dependency for this program is libgit2. Install that on debian distros with # apt install libgit2-1.1.

Building the package

To build the program, run gcc -o $HOME/bin/prompt liteprompt.c -lgit2. This will create an executable in the directory ~/bin called prompt.

Adding the File the .zshrc

To your zshrc, add:

prcmd() {
  PROMPT=`prompt`
}

Source the updated zshrc, and the prompt should be displaying in full color.

For updates

To have the updates file. Add the following to the user crontab:

10 * * * * apt list --upgradable > ~/.updates 

And to a super user crontab add:

15 * * * * apt update
