## What it is
powerline-go is a fast, low-latency Powerline-style shell prompt written in Go, supporting Bash, ZSH, Fish, and PowerShell. It displays git/hg branch status, exit codes, virtualenvs, and other context with customizable themes and segments.

## Use cases
- show git branch and dirty status in my shell prompt
- make my terminal prompt show python virtualenv and ruby version
- get a fast low-latency powerline prompt for bash zsh or fish
- color my prompt red when the last command failed
- shorten long directory paths in the shell prompt
- customize shell prompt segments and color scheme

## When to choose
- you use Bash, ZSH, or Fish and want a Powerline-style prompt with minimal latency
- you want built-in git/hg status, virtualenv, rbenv, and nix shell indicators
- you prefer a single static Go binary over Python-based prompt tools

## When to avoid
- you need a highly extensible prompt framework with a plugin ecosystem like oh-my-zsh or starship
- your terminal cannot render ANSI colors or powerline glyphs and you don't want to install patched fonts

- function: cli, developer-tools, theme
