~/.bashrc

Bash prompt

To use, overwrite the default definitions of PS1 in ~/.bashrc.

Includes conda and virtualenv environments as well as the current git branch, if any. Set changeps1: false in ~/.condarc and add export VIRTUAL_ENV_DISABLE_PROMPT=1 to ~/.bashrc to to disable the default prompt modifications by conda and virtualenv, respectively.

Colored version:

PS1=''  # set to empty string; allows easy rearrangement of components
PS1+='\[\033[0;32m\]\u @ \h '  # user and host
PS1+='\[\033[0;34m\]<conda: $(basename ${CONDA_DEFAULT_ENV:-"none"})> '  # conda environment
PS1+='\[\033[0;35m\]<venv: $(basename ${VIRTUAL_ENV:-"none"})> '  # virtualenv environment
PS1+='\[\033[0;36m\]\w'  # current directory
PS1+='\[\033[0;33m\]$(__git_ps1)'  # current git branch
PS1+='\n'  # newline
PS1+='\[\033[0;32m\]└─ '  # formatting newline
PS1+='\[\033[0;32m\]\$ '  # type of prompt (user vs root)
PS1+='\[\033[0;30m\]▶  '  # formatting cursor position signal
PS1+='\[\033[0m\]'  # reset format for user input

Uncolored version:

PS1=''  # set to empty string; allows easy rearrangement of components
PS1+='\u @ \h '  # user and host
PS1+='<conda: $(basename ${CONDA_DEFAULT_ENV:-"none"})> '  # conda environment
PS1+='<venv: $(basename ${VIRTUAL_ENV:-"none"})> '  # virtualenv environment
PS1+='\w'  # current directory
PS1+='$(__git_ps1)'  # current git branch
PS1+='\n'  # newline
PS1+='└─ '  # formatting newline
PS1+='\$ '  # type of prompt (user vs root)
PS1+='▶  '  # formatting cursor position signal

Example (no colors):

user @ host <conda: conda-env-name> <venv: virtualenv-name> ~/path/to/repo (git-branch-name)
└─ $ ▶
