必备的Emacs扩展？

emacsemacspeak

我现在正在尝试使用http://emacspeak.sourceforge.net，因为我已经在Windows上运行它了。我想将emacs用作不仅仅是纯文本编辑器，并想知道每个人都不能没有的扩展/包是什么？我最常使用的语言是Perl、Java和一些C/C++。

我喜欢 颜色主题，当然也包括我正在使用的语言模式。

我也使用了一段时间的颜色主题，但在cperl-mode中发现了一些奇怪的减速。关闭color-theme后问题消失了（可能是某些复杂的第三方交互引起的，谁知道呢！）。 - Michael Paulukonis

我喜欢让我的编辑器完全按照我的意愿来操作。因此，我写了一堆插件来微调它们。下面列出了一些标准包，如果没有它们，我会很难受：

  • gnus
  • tnt - AOL IM客户端（我帮助维护）
  • jabber
  • git-emacs
  • camel-case
  • swbuff（和我的swbuff-advice扩展）
  • dired

以下是我写的一些我永远不会放弃的插件（这就是为什么我写它们的原因）：

  • whole-line-or-region - 当未定义区域时剪切和粘贴整行
  • cua-lite - 一个轻量级CUA包
  • dired-single - 将dired限制为单个可重复使用的缓冲区
  • hobo - tramp替代品，还不够成熟

此外，正如Charlie提到的，当你无聊时只需浏览EmacsWiki。你总能找到新的东西尝试。我阅读gnu.emacs.sources以查看人们所提供的最新和最棒的。
