  劉據被藍田一頓搶白,一時間不知道該如何應對,偷偷地看了一眼父親見他已經微皺眉頭,連忙道︰“我是說,雲哲打碎了父皇的珍寶,就是大不敬,更應該拿出誠意來,一件翻車不足論,怎麼也該是那件飛天神器才成!”   “背叛過的就不能饒恕是嗎?”色播五月   彪形大漢笑道︰“一個人就夠了。”色五月   霍光非常無奈的道。   不知為何瑕丘江公忽然變得憤怒起來,沖著雲瑯怒吼道︰“天地本無仁心,且喜怒無常,我們活在天地間已經悲苦不堪,生老病死各安天命。你們這些人居于高天之上,手握雷霆,不曾讓天下風調雨順,反而時時降下雷霆,讓百姓如犬豕一般疲于奔命。嘗聞古聖人當政之時,為百姓驅逐猛獸,治療疾病,架屋築城保全性命,所以稱之為聖。爾等居然有臉面自稱為聖人,不過一群賊人而已。”开心五月   張安世擔憂的道︰“也就是說你打算一直這麼干下去是吧?”

Company is a text completion framework for Emacs. The name stands for "complete anything". It uses pluggable back-ends and front-ends to retrieve and display completion candidates.

It comes with several back-ends such as Elisp, Clang, Semantic, Eclim, Ropemacs, Ispell, CMake, BBDB, Yasnippet, dabbrev, etags, gtags, files, keywords and a few others.

The CAPF back-end provides a bridge to the standard completion-at-point-functions facility, and thus works with any major mode that defines a proper completion function.


company-elisp company-semantic


This package is part of GNU ELPA (M-x list-packages).

Advanced users can also download the development snapshot.


Once installed, enable company-mode with M-x company-mode.

Completion will start automatically after you type a few letters. Use M-n and M-p to select, <return> to complete or <tab> to complete the common part. Search through the completions with C-s, C-r and C-o. Press M-(digit) to quickly complete with one of the first 10 candidates.

Type M-x company-complete to initiate completion manually. Bind this command to a key combination of your choice.

When the completion candidates are shown, press <f1> to display the documentation for the selected candidate, or C-w to see its source. Not all back-ends support this.

To use company-mode in all buffers, add the following line to your init file:

(add-hook 'after-init-hook 'global-company-mode)

To see or change the list of enabled back-ends, type M-x customize-variable RET company-backends. Also see its description for information on writing a back-end.

For information on specific back-ends, also check out the comments inside the respective files.

For more information, type M-x describe-function RET company-mode.

To customize other aspects of its behavior, type M-x customize-group RET company.
