写了一份 Racket/Emacs 的入门配置指南

[keyanzhang]

这个学期在做 Dan Friedman 先生的课程助教。上课需要用到 Racket ，所以我写了一份简单的 Emacs 配置指南；如果你想使用 racket-mode 又还没用过 Emacs ，这份文档可能是不错的起点。如有疏漏还请不吝 Issue 和 PR ：）

init.el 中包含的内容如下：

• Automatic package installation, including:
  • racket-mode for all the greatness.
    • We rebind the racket-run command to meta-enter (option-enter). This is basically equivalent with DrRacket's Run button. If you don't like the keybinding, just modify it in init.el.
  • helm cuz nobody can memorize all the emacs functions.
  • company for auto completion.
  • rainbow-delimiters so we won't need to get LASIK.
  • paredit is included but disabled by default.
    • We highly recommend activating paredit for Scheme/Racket/Lisp modes, but we understand that it could take a while to get used to it.
    • Please read http://danmidwood.com/content/2014/11/21/animated-paredit.html first; when you are ready, change the line (setq paredit-enabled nil ) to (setq paredit-enabled t ) in init.el to activate paredit.
• Fixes
  • All the temporary files will be placed under ~/.emacs.d/bkup so you won't see annoying bla~ files in your working folder again.
  • The Mac option key becomes meta.
  • Perserve some OS X default system shortcuts in Emacs. To name a few:
    • Command-a = "Select All"
    • Command-x = "Cut", Command-c = "Copy", and Command-v = "Paste"
    • Command-s = "Save"
    • Command-z = "Undo"
  • recentf-mode: use C-x C-r to access a list of recently edited files.
  • Emacs grabs the $PATH variable from your shell.
