#+TITLE: Bash Config
#+PROPERTY: header-args+ :mkdir p yes
#+PROPERTY: header-args+ :tangle ~/.bashrc

Export =SHELL= to child processes. Programs such as ~screen~
honor it and otherwise use ~/bin/bash~
#+begin_src bash
  export SHELL
#+end_src

We are being invoked from a non-interactive shell. If this is an
SSH session (as in =ssh host command=), source ~/etc/profile~ so we
get =PATH= and other essential variables.
#+begin_src bash
  if [[ $- != *i* ]]
  then
      [[ -n "$SSH_CLIENT" ]] && source /etc/profile

      return
  fi
#+end_src

Make sure we have the system-wide config.
#+begin_src bash
  source /etc/bashrc
#+end_src

Adjust the prompt depending on wheather we're in a [[https://guix.gnu.org/manual/en/html_node/Invoking-guix-environment.html][guix environment]].
#+begin_src bash
  if [ -n "$GUIX_ENVIRONMENT" ]
  then
      PS1='\u@\h \w [env]\$ '
  else
      PS1='\u@\h \w\$ '
  fi
#+end_src

* History
  By default, Bash write its history at the end of each session, overwriting the existing file with an updated version.
  This means if multiple bash session are open, only the last one to exit will have its history saved.
  #+begin_src bash
    shopt -s histappend
  #+end_src

  Most of the time the following commands just clutter up history or obscures usefull entries. Ignore the following commands
  #+begin_src bash
    export HISTIGNORE='exit:ls:ll:cd:pwd:bg:fg:history'
  #+end_src

* Aliases
  #+begin_src bash
    alias ls='ls -p --color=auto'
    alias ll='ls -l'
    alias grep='grep --color=auto'
  #+end_src

* Variables
  #+begin_src bash
    export BROWSER=vimb

  #+end_src
  Guix
  #+begin_src bash
    export GUIX_PROFILE="$HOME/.guix-profile"
