#+TITLE: ZSH

Autoload any ZSH function from =$HOME/.zsh/functions=.

#+BEGIN_SRC sh
  fpath=($HOME/.zsh/functions $fpath)
  autoload -U $HOME/.zsh/functions/*(:t)
#+END_SRC

* Aliases

  Use rlwrap on some less-than-pleasant REPLs that don't have GNU
  Readline-like features themselves.

  #+BEGIN_SRC sh
    alias csi="rlwrap csi"
    alias scsh="rlwrap scsh"
    alias sbcl="rlwrap sbcl"
  #+END_SRC

* History

  Store ZSH history in a non-intrusive place.

  #+BEGIN_SRC sh
    HISTFILE=$HOME/.zsh/histfile
  #+END_SRC

  Keep at most 1000 previous commands in memory.

  #+BEGIN_SRC sh
    HISTSIZE=1000
  #+END_SRC

  Save at most 1000 previous commands to disk.

  #+BEGIN_SRC sh
    SAVEHIST=1000
  #+END_SRC

  Allow multiple shell instances to share the same history.

  #+BEGIN_SRC sh
    setopt SHARE_HISTORY
  #+END_SRC

  Don't remember duplicated commands.

  #+BEGIN_SRC sh
    setopt HIST_IGNORE_ALL_DUPS
  #+END_SRC

* Plug-ins

  Load zplug, a next generation zsh plugin manager.

  #+BEGIN_SRC sh
    source /usr/share/zsh/scripts/zplug/init.zsh
  #+END_SRC

  Add zsh-syntax-highlighting.

  #+BEGIN_SRC sh
    zplug "zsh-users/zsh-syntax-highlighting", nice:10
  #+END_SRC

  Add zsh-autosuggestions.

  #+BEGIN_SRC sh
    zplug "zsh-users/zsh-autosuggestions"
  #+END_SRC

  Add bgnotify from oh-my-zsh to show when long-running commands finish.

  #+BEGIN_SRC sh
    zplug "plugins/bgnotify", from:oh-my-zsh
  #+END_SRC

  Make sure all plugins are installed.

  #+BEGIN_SRC sh
    if ! zplug check --verbose; then
        printf "Install? [y/N]: "
        if read -q; then
            echo; zplug install
        fi
    fi
  #+END_SRC

  Load all plugins.

  #+BEGIN_SRC sh
    zplug load --verbose
  #+END_SRC

* X Interaction

  Make some widgets for interacting with the clipboard.

  #+BEGIN_SRC sh
    zle -N x-copy-region-as-kill
    zle -N x-kill-region
    zle -N x-yank
  #+END_SRC

  Bind them to keyboard shortcuts.

  #+BEGIN_SRC sh
    bindkey -e '^[w' x-copy-region-as-kill
    bindkey -e '^W' x-kill-region
    bindkey -e '^Y' x-yank
  #+END_SRC

* Completion

  Initialize completion. This triggers loading of
  zsh-syntax-highlighting as well.

  #+BEGIN_SRC sh
    autoload -Uz compinit
    compinit
  #+END_SRC
