My prompt remained largely unchanged for a long time until I came across
this article written by the excellent Mark Otto (of Twitter bootstrap fame).
In the article he provides a code snippet for your .bash_profile
to turn your
standard prompt into this:
I loved it and started using it myself straight away. Unfortunately there were a few issues with it. The prompt would fragment or completely disappear when cycling up or down through my command history and I encountered horrible line wrapping issues.
The issues were mostly resolved in a later article and solved entirely by this lovely gist. The follow up included code that would change the colour of your working git branch depending on its status.
This seemingly insignificant feature is incredibly useful. I’m constantly reminded to commit my work, resulting in frequent, small commits rather than behemoths where I’ve completely forgotten when, why and what code I’ve changed.
I coloured the prompt with the help of this wonderful article by Michael Plotke and the colour value table on the Solarized site. Here is a basic but handy script I made for displaying the colours. (the value need for Terminal is the XTERM column)
#!/bin/bash
#
# generates an 8 bit color table (256 colors) showing the colors used by
# Ethan Schnoover's Solarized theme
printf "\nSWATCH SOLARIZED HEX 16/8 TERMCOL XTERM/HEX L*A*B RGB HSB "
printf "\n------ --------- ------- ---- ------- ----------- ---------- ----------- -----------"

I was feeling pretty happy with myself at this point; the colourscheme was great, the font was inviting and my bash prompt looked cool and was actually useful to me.
