pragmaprompt

A pragmatic bash prompt done by a fish-shell user!

Lighweight and simple, no bloat
Fast, optimized for low latencies
Code validated using bashate and shellcheck
Intended to be compatible and quite POSIX.

Supports prompting of:

Username (in warning red if root)
Timestamp of last command (see DATE_FMT)
Return value of last command
State of version control (powered by vcprompt - see VCPROMPT_FMT)
Active Python virtualenv or current version managed by pyenv
Use of a multiplexer (screen or tmux).

Tested on iTerm2 nightlies:

brew cask install iterm2-nightly

Installation

Homebrew

$ brew install https://raw.githubusercontent.com/gretel/pragmaprompt/master/pragmaprompt.rb

Please follow the instructions shown:

The prompt needs to be enabled manually.
Please add the following to your .bashrc:
    if [ -f "$(brew --prefix pragmaprompt)/share/pragmaprompt.sh" ]; then
        source "$(brew --prefix pragmaprompt)/share/pragmaprompt.sh"
    fi
Then, you may restart the shell:
    exec bash

Manually

Clone this repository or get the file somehow and put it somehwere like ~/pragmaprompt.sh.

Finally, include the file in your .bashrc or .bash_profile:

if [ -f "$HOME/pragmaprompt.sh" ]; then
    source "$HOME/pragmaprompt.sh"
fi

Integration

While truly optional the following tool is supported:

vcprompt - git, hg, and svn info at low latencies
pyenv - the currently activated virtualenv is shown - nice for Python hack*etc - otherwise maybe not.

On OS X homebrew can be used to get these:

brew install pyenv --HEAD
brew install tmux --HEAD
brew install vcprompt --HEAD

Using HEAD versions is optional but recommended especially in regards to vcprompt.

The bitbucket repo of vcprompt homebrew's HEAD formulae uses is one of the few actually being maintained.

Terminal Settings

A recommandable and well-matching font:

Literation Mono
