春、新しいiMac

久しぶりにEl Capitanをゼロから環境構築したのでメモ。

想定ユーザ

Macにはそこそこ慣れてる
そこそこトレンドに乗れてれば超最新でなくてもOK
Pythonをサクッと使いたい
- pyenvとかVirtualenvは面倒だけどPySideやJupyterは使いたい、的な
Zsh派
Vim派

基本方針

アプリケーションのインストールはなるべくHomebrew+Caskで
Vimのパッケージ管理は話題のDein.vim
- "Neobundle development is done."
Python周りはAnacondaに任せた
統合されたPowerlineで見た目も綺麗に
dotfilesを他のマシンで使いまわしても手間がなるべく増えないように心がける

手順

Homebrew+Caskのインストール

散々既出なので詳細割愛。

$ xcode-select --install
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

今回はまっさらなEl Capitanへのインストールだったので、何も考えずに公式通り。
Yosemiteからのアップデート時にはシステム保護機能"Rootless"に要注意。

Zshのインストール

散々既出なので(rya

$ brew install zsh --without-etcdir
$ brew install z zsh-completions zsh-history-substring-search zsh-syntax-highlighting
$ sudo echo "/usr/local/bin/zsh" >> /etc/shells
$ chsh -s /usr/local/bin/zsh

iTerm2のインストール

Beta版で使える"Shell Integration"が素敵だけど、
基本方針1「アプリケーションのインストールはなるべくHomebrew+Caskで」に遵守。

$ brew cask install iTerm2

pyenvとAnacondaのインストール（2016/03/24追記）

そもそも、ゼロから環境構築しようと思ったのはこの記事を読んだから。
→ データサイエンティストを目指す人のpython環境構築 2016 - Qiita

AnacondaがHomebrewの環境を壊す可能性があるので、pyenvをかませる。
以後の仮想環境はAnacondaで設定するので、pyenvするのはこの1回きり。

$ brew install pyenv
$ pyenv install anaconda3-2.5.0
$ pyenv global anaconda3-2.5.0
$ pyenv rehash

MacBookAirなどで容量逼迫してるならMinicondaでも良いかも。

Vimのインストール

Dein.vimは7.4以上(またはNeoVim)でなければいけないので入れ直す。

$ brew install lua luajit
$ brew install vim --override-system-vi --with-lua --with-luajit --with-python3

途中、依存するpythonが勝手にインストールされるが、AnacondaのPythonを優先参照するように.zshrcを書き換えるので問題なし。
※ 記事末に.zshrcを全文晒します。
それまでは下記を実行しておく。不安な人は都度python -Vして確かめながら進めてください。

$ export PATH=~/anaconda3/bin:"$PATH"

Dein.vimのインストール

Shougoさんに感謝しつつ、下記を実行。

$ curl https://raw.githubusercontent.com/Shougo/dein.vim/master/bin/installer.sh > installer.sh
$ sh ./installer.sh ~/.vim/dein

慣例がないのでなんとなく~/.vim/deinにインストール。
続きは.vimrcで。

Powerlineのインストール

公式Doc通り。

$ pip install --user powerline-status

Anaconda環境でインストールするとpowerlineコマンド群は~/.local/binにインストールされるようだ。
ということで、こんな感じに追記。
※ 記事末に.zshrcを全文晒します。

## Powerline
# https://powerline.readthedocs.org/en/master/
if [ -d ~/.local/bin ]; then
  export PATH="$PATH":~/.local/bin
  powerline-daemon -q
  . ~/.local/lib/python3.5/site-packages/powerline/bindings/zsh/powerline.zsh
fi

基本方針5「dotfilesを他のマシンで使いまわしても手間がなるべく増えないように心がける」的にはまだ不十分だけど、とりあえず。

Powerline用フォントのインストール

パッチを当てるのは面倒なのでパッチ済みのフォントをGitHubからダウンロード。
→ https://github.com/powerline/fonts
解凍してinstall.shを実行すればまとめて全部インストールされる。

dotfiles

準備が整ったので、設定ファイルをガッと。

.zshrc

OSに依存しない設定を.zshrc、OS依存する設定を.zshrc.mine.(osx|ubuntu|cent)、マシン依存する設定(職場のproxy設定など)を.zshrc.machineとして記述分け。

.zshrc

微調整 & 諸注意

LC_ALLがないとPowerlineに怒られる

気持ち悪いけど、.zshrcにLC_ALLを書いておけば回避可能。

.zshrc

export LANG=ja_JP.UTF-8
export LC_ALL='ja_JP.UTF-8'

特にVimのステータスラインが乱れる

iTerm2のProfileにはRegular FontとNon-ASCII Fontの設定があり、三角形はNon-ASCII Fontの方で描画されているので、
どちらもpatch済みのフォントを設定し、
"Treat ambiguous-width characters as double width"のチェックは外す。
この辺はPowerlineのconfigで追い込むほうが早い。

完成

作業時間は正味、15分ぐらい。「桜舞い散る中に忘れた記憶」とならないようメモメモ。
