自分のPCで設定しているソフトウェア,設定の紹介

今回はzsh(zshell)の起動時に読み込むファイルの紹介をしたいと思います。 全体の流れと共に,順番に説明していきます。

zshrc

以下が~/.zshrcです。

dotfiles/zshrc at master · ssh0/dotfiles · GitHub

まず環境変数ZSH_ROOTを設定します。(他の設定で使う)

# Set the zsh root directoy
export ZSH_ROOT=$HOME/.zsh

fzf

次にfzfを有効化(もしインストールされていなければ後でインストール)

# Using fzf
if [ ! -f ~/.fzf.zsh ]; then
  # install fzf
  function _install_fzf() {
    confirm y "fzf is not installed. Start installation ? "
    git clone --depth 1 https://github.com/junegunn/fzf.git ~/.fzf
    ~/.fzf/install
  }
  install_fzf=true
else
  source ~/.fzf.zsh
  install_fzf=false
fi
export FZF_COMPLETION_TRIGGER=''

環境変数を設定

言語などの環境変数を設定していきます。

# Set some environmet variables
source "$ZSH_ROOT/functions/environment.zsh"

~/.zsh/functions/environment.zsh

export ZSH_CACHE_DIR=$ZSH/cache

# PATH to /usr/local/lib
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

# XDG_CONFIG_HOME
export XDG_CONFIG_HOME=$HOME/.config

# set language environment
export LANG=en_US.UTF-8
export MANLANG=ja_JP.UTF-8
export LC_TIME=en_US.UTF-8

# python startup
export PYTHONSTARTUP="$HOME/.pythonrc.py"

環境変数を利用して,デフォルトのアプリケーションを設定します。

find_altという関数を定義して,引数にとったコマンドをhash関数で存在を確認し,そのコマンドを設定します。

# find alternative apps if it is installed on your system
find_alt() {
  local i
  for i in $@; do
    hash "$i" 2>/dev/null && echo "$i" && return 0
  done
  return 1
}

# set the default program
# the first program in the array will be chosen as the default
export OPENER=$(find_alt xdg-open exo-open gnome-open )
export BROWSER=$(find_alt firefox luakit google-chrome chromium chromium-browser $OPENER )
export BROWSERCLI=$(find_alt w3m links2 links lynx elinks $OPENER )
export EDITOR=$(find_alt nvim vim emacs nano leafpad gedit pluma $OPENER )
export FILEMANAGER=$(find_alt thunar nautilus dolphin pcmanfm tspacefm enlightenment_filemanager $OPENER )
export PAGER=$(find_alt less more most)
export PERCOL=$(find_alt fzf peco percol)
export PLAYER=$(find_alt mpv mplayer cvlc $OPENER )
export READER=$(find_alt mupdf zathura evince $OPENER )
export TERMCMD=$(find_alt urxvt xterm gnome-terminal)

unfunction find_alt

サードパーティソフトウェアで用いられる環境変数を設定

# To stop ranger from loading both the default and my custom rc.conf
export RANGER_LOAD_DEFAULT_RC=false

# override the safe location for pick
# export PICK_SAFE="$HOME/Dropbox/conf/pick.safe"

# enhancd by "cd"
export ENHANCD_COMMAND='cd'

# dot
export DOT_COMMAND='d'

# takenote
export TAKENOTE_ROOTDIR="$HOME/Workspace/blog"
export TAKENOTE_FILERCMD=ranger

# shtest
export SHTEST_FILENAME_PRE="test_"
export SHTEST_FILENAME_EXTENSION="sh"

# cheat
# -----
# cheat allows you to create and view interactive cheatsheets on the
# command-line. It was designed to help remind *nix system administrators of
# options for commands that they use frequently, but not frequently enough to
# remember.
# [chrisallenlane/cheat](https://github.com/chrisallenlane/cheat)
# sudo pip install cheat
export CHEATCOLORS=true

export PC=

ls時の色を設定

ivoarch/dircolors-zenburnを使わせてもらっています。

# dircolors
eval $(dircolors "$ZSH_ROOT/dircolors/dircolors-zenburn")

tmux関連の設定

起動時にtmuxを自動起動(前回紹介)

# tmux plugin should be loaded as much as first of zshrc.
# Only run if tmux is actually installed.
hash tmux 2>/dev/null && source "$ZSH_ROOT/functions/tmux.zsh"

zshプラグインを有効化

zgenもしくはzplugを使ってzshプラグインを管理しています。

# Use zgen to load some zsh plugins
source "$ZSH_ROOT/functions/zgen.zsh"

# zplug
#source "$ZSH_ROOT/functions/zplug.zsh"

使用しているzshプラグイン

  • b4b4r07/enhancd zsh
  • chrissicool/zsh-256color
  • ssh0/dot
  • ssh0/zsh-takenote
  • fcambus/ansiweather
  • Tarrasch/zsh-bd
  • zsh-users/zsh-syntax-highlighting

補完関連の設定

# Add fpath for completions
# There are completion functions named like '_function'.
fpath=($ZSH_ROOT/completions $fpath)

source "$ZSH_ROOT/functions/completion.zsh"

autoload -U compinit
compinit -D

~/.zsh/completions以下に,_コマンド名の形式で補完関数を置いておき,fpathに追加しておくことで補完できるようになります。
