ソフトウェアアップデート

システム環境設定＞ソフトウェアアップデート

Xcode のインストール

AppStoreからXcodeをインストールする．
(Xcode自体を用いないなら不要)

Homebrewを用いてソフトウェアのインストール

以下のHomebrewのサイトに従い，Homebrewを導入する．
http://brew.sh/

install-homebrew

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

brew-install

$ brew install zsh-completion
$ brew install wget
$ brew install bat
$ brew install lsd
$ brew install nkf

$ echo 'export HOMEBREW_CASK_OPTS="--appdir=/Applications"' >> ~/.zshrc

brew-cask-install

$ brew cask install iterm2
$ brew cask install slack
$ brew cask install mactex
$ brew cask install istat-menus
$ brew cask install karabiner-elements
$ brew cask install google-japanese-ime
$ brew cask install google-backup-and-sync
$ brew cask install alfred
$ brew cask install google-chrome
$ brew cask install sublime-text
$ brew cask install visual-studio-code
$ brew cask install java

nodeの最新版（ここではv11.13.0）をインストールしてnodeにPATHを通す

install-node

$ brew install nodebrew
$ nodebrew setup
$ nodebrew install-binary latest
$ nodebrew use v11.13.0
$ echo 'export PATH=$PATH:$HOME/.nodebrew/current/bin' >> ~/.zprofile

Finderに隠しファイルを表示

$ defaults write com.apple.finder AppleShowAllFiles TRUE
$ killall Finder

参考:https://qiita.com/dich1/items/a6da541d31429422b99f

Python環境の構築

pyenvのインストール

$ brew install pyenv
$ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zprofile
$ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zprofile
$ echo -e 'if command -v pyenv 1>/dev/null 2>&1; then\n  eval "$(pyenv init -)"\nfi' >> ~/.zshrc
$ source ~/.zprofile
$ source ~/.zshrc
$ echo 'eval "$(pyenv init -)"' >> ~/.zprofile
$ exec $SHELL -l

(推奨）pyenv+pythonを用いる場合

Anacondaとpipを共存させると問題が発生することがあるので，pyenv+pythonで管理することをおすすめする．

python3.8.1(2020/02/15時点最新)をインストールしてglobalに設定する．
pip listでインストールされているパッケージを確認すると，新しいバージョンのpipが使えると言われたので，
pipをアップグレードして，必要なパッケージをインストールする．

$ pyenv install 3.8.1
$ pyenv global 3.8.1
$ pip install --upgrade pip
$ pip install (packages)

（非推奨）Anacondaを用いる場合

$ pyenv install anaconda3-5.3.1
$ pyenv global anaconda3-5.3.1

参考: https://qiita.com/tanuk1647/items/3cf2f4a348220d90c612
https://techa1008.com/rocket-note/2018/07/25/install-anaconda-on-mac-and-start-jupyter-notebook/

anacondaをアンインストールする場合

$ conda install anaconda-clean
$ anaconda-clean
$ rm -rf /Users/<username>/.anaconda_backup
$ pyenv uninstall anaconda3-5.3.1

.bash_profile中のPATHを追加する記述を削除し，（残っていたら）アプリケーションからショートカットを削除して完了．

Anaconda3をmacOSから完全にアンインストールする方法

TeXの日本語環境構築

tlmgrで最新版にアップデート（１時間近くかかった気がする）

$ sudo tlmgr update --self --all

$ sudo tlmgr repository add http://contrib.texlive.info/current tlcontrib
$ sudo tlmgr pinning add tlcontrib '*'
$ sudo tlmgr install japanese-otf-nonfree japanese-otf-uptex-nonfree ptex-fontmaps-macos cjk-gs-integrate-macos
$ sudo cjk-gs-integrate --link-texmf --cleanup --force
$ sudo cjk-gs-integrate-macos --link-texmf --force
$ sudo mktexlsr
$ sudo kanji-config-updmap-sys --jis2004 hiragino-highsierra-pron

$ defaults write TeXShop FixLineNumberScroll NO
$ defaults write TeXShop SourceScrollElasticity NO
$ defaults write TeXShop FixPreviewBlur YES

参考:http://doratex.hatenablog.jp/entry/20180501/1525144736

latexmkファイル（Spacemacsで使用）を作成しておく．

latexmk

# !/usr/bin/env perl
$ latex            = 'platex -synctex=1 -halt-on-error';
$ latex_silent     = 'platex -synctex=1 -halt-on-error -interaction=batchmode';
$ bibtex           = 'pbibtex';
$ dvipdf           = 'dvipdfmx %O -o %D %S';
$ makeindex        = 'mendex %O -o %D %S';
$ max_repeat       = 5;
$ pdf_mode	  = 3; # generates pdf via dvipdfmx

# Prevent latexmk from removing PDF after typeset.
# This enables Skim to chase the update in PDF automatically.
$ pvc_view_file_via_temporary = 0;

# Use Skim as a previewer
$ pdf_previewer    = "open -ga /Applications/Skim.app";


# ファイル更新の度にgit commit したい場合
# $ pdf_update_command = "git commit -am'update'";

Spacemacsの設定

公式のインストール手順に従ってインストール．

GitHub(ssh)の設定

参考: GitHub Help
GitHubにSSH接続できるようにする方法

1. ssh鍵の作成

$ ssh-keygen -t rsa -b 4096 -C "email@example.com"
> Enter a file in which to save the key (/Users/you/.ssh/id_rsa): /Users/you/.ssh/git_id_rsa [Press enter]

2. Mac側の設定の保存

~/.ssh/configファイルに以下を追記する．

Host github.com
  HostName github.com
  IdentityFile ~/.ssh/git_id_rsa
  User git

3. SSHの秘密鍵をssh-agentに追加

$ ssh-add -K ~/.ssh/git_id_rsa

4. GitHubへの公開鍵の登録

git_id_rsa.pub内に記載されているkeyをGitHubの設定ページで貼り付け．

5. 確認

$ ssh -T git@github.com

5. ローカルリポジトリの設定を変更する

$ git remote set-url origin git@github.com:<username>/<repositoryname>
