go-prompt

A tiny Go program that generates my WSL bash prompt.

Example

You can try it out like this (note that this is actually colorized):

$ go run go-prompt.go 123 && echo
alinz@DESKTOP-NK6M18P in ~/code/go-prompt git:master errno:123
> 

Setup

Run make install and patch your .bashrc like this (or see this example):

git diff HEAD~
diff --git a/.bashrc b/.bashrc
index 2e8200d..863c583 100644
--- a/.bashrc
