让 Emacs 支持 Lion 的全屏模式

Permalink

前几天给我的 MacBook Pro 装上了 Lion,不过原来的 Emacs 并不支持在 Lion 下全屏运行。github 上搜了下发现已经有让 Emacs 支持全屏模式的补丁了,Homebrew 中这个补丁也已经被吸收

直接用 brew install emacs --cocoa --srgb 似乎会碰到编译错误:

github issues 上已经有人报告这个问题了,解决方法也很简单,运行 brew edit emacs 打开 emacs 的安装脚本,在 def install 的后面加上两行:

  def install
    ENV['CFLAGS']='-fno-pie -O2'
    ENV['LDFLAGS']='-fno-pie'
    args = ["--prefix=#{prefix}",
            "--without-dbus",
            "--enable-locallisppath=#{HOMEBREW_PREFIX}/share/emacs/site-lisp",
            "--infodir=#{info}/emacs"]
    # ...

再运行一次 brew install emacs,就能在 /usr/local/Cellar/emacs/23.3 下找到支持全屏模式的 Emacs.app 了。M-x ns-toggle-fullscreen 可以在全屏/非全屏模式之间切换。
