# Taking a few things from my fish cfg back to bash: vi keys, branch name in prompt, custom prompt, completion (with fzf)
# Custom prompt
# Vi keys
# History
# Completion (Using fzf & fzf-tab-completion)

# Tip: Install bashmarks and fasd for faster directory browsing

# Custom prompt: Add to .bashrc
# Helps reset prompt when tty crashes
PROMPT_COMMAND='stty sane; tput rmacs'

# Custom prompt, originally generated from bash-prompt-generator.org
PS1='\[\e[2m\](\[\e[0;38;5;202m\]$(git branch 2>/dev/null | grep '"'"'*'"'"' | colrm 1 2)\[\e[0;2m\]) \[\e[0;38;5;214m\]\w\033[0m\n\[\e[38;5;242m\]\t \[\e[0m\]'
