My Emacs Configuration Table of Contents What is it? How to install my configure The most complicated part Code location 1 What is it? I have at least three desktop machines works right now, running Mac OS and Linux. I found that's a messy and dirty job to configure my emacs again and again after reinstalling the system. This project is a convenience collection my configurations of emacs and reinstalls them quickly into another machine. I had worked in a similar project formerly, not a so pleasure experience, I commit everything located in ~/.emacs.d into a git repository, after realize how silly it is, I abandon that project. This new project is an upgraded version, more light weight, just upload my own configuration without the third party modules. 2 How to install my configure steps 1 create your .emacs.d directory into your home directory cd ${ HOME } mkdir .emacs.d steps 2 clone the code into your ${HOME}/.emacs.d directory cd ${ ...

tts-mode for emacs update - support Mac OS X's tts engine Table of Contents 1 Support Mac OS X's default tts engine 2 Configure and Install tts-mode 1 Support Mac OS X's default tts engine After I owned an Macbook air, I tried to port tts-mode into OS X system. I installed espeak command line tool into OS X, it works well just like in linux system. Thanks to the excellent portability of elisp source code, I need not to change any source code. I still have not installed festival tts engine into Mac OS, but it seems have many tutorials to do it. After that I found OS X's default tts engine, which provide an command line interface, has much clearer and greater fluency than both espeak and festival. So I wonder if I can support OS X's default tts engine. Then here it is, the new tts-mode . 2 Configure and Install tts-mode Reference the following codes: (add-to-list 'load-path "path/to/tts-mode" ) ;; configure tts engine...

Configure Emacs as a Python IDE Table of Contents 1 use python.el 2 auto-completion in python.el 1 use python.el There are plenty of python modes which support develop python in emacs, well, in my personal opinion, most of those are sucks, and F fgallina's python.el is the much better one.  Besides the major mode for python, I installed following python packages including rope, ropemode, Pymacs, and ropemacs. Install rope, reopmode, and ropemacs were really easy with the help of python's package management tool pip .  pip install rope pip install ropemode pip install ropemacs Pymacs provided the both-way communication between Emacs Lisp and Python, it can not installed by pip, so just download the source code from GitHub.  Install pymacs python package first.  make sudo make install Install emacs package pymacs.el which generated by above step. copy pymacs.el into the path which included in emacs's load-path. Then add the fol...

Configure eshell-mode after upgrade emacs to 24.3.1 My eshell-mode doesn't works after I upgrade emacs to 24.3.1. I got the empty symbol "eshell-output-filter-functions" error every time I start eshell-mode.  The symbol "eshell-output-filter-functions" located in esh-mode.el. So I need to load the esh-mode.el before the code which refers to the "eshell-output-filter-functions" symbol.  After that My eshell-mode's configure code is as following:  (setq eshell-cmpl-cycle-completions nil eshell-save-history-on-exit t eshell-cmpl-dir-ignore "\\` \\ ( \\.\\.? \\ | CVS \\ | \\.svn \\ | \\.git \\ ) /\\'" ) ;; load esh-mode first ( require ' esh-mode ) ( eval-after-load 'esh-opt '( progn ( require ' em-cmpl ) ( require ' em-prompt ) ( require ' em-term ) ;; TODO: for some reason requiring this here breaks it, but ;; requiring it after an eshell session is s...

Using TextMate-mode in Emacs As an emacs user, I was always being surprised by some fabulous modes. This time is TextMate-mode, which is a really useful minor mode for the plain text editor.  As a software developer, I always need to jump to some parts of the source code. Command, M-x textmate-goto-symbol, can really kick my ass.  Another thing which exciting me is the jump to a file by command M-x textmate-goto-file. Also, it only works when I am working in a git repository. It just gives me what I needed.  Are there any other functions in this mode which enlightening me? Well, Maybe it makes my tears running down again by other amazing tricks.

Using GNU Global to navigating source code I use etags as the default tagging system to navigating the C-like source code before. It works good, but sometimes it didn't perform as good as ctags which were used by vimer. Table of Contents 1 why not etags? 2 gtags's advantage 3 gtags's disadvantage 4 Install gtags 5 tagging source code systems of emacs 1 why not etags? Etags has a flaw compared with ctags, which is it didn't pop up the mini-buffer when searching a symbol. Which means I can not get options then decide where to jump when multi locations match the symbol. I have to jump one by one to find the right location in emacs with etags，which push me over the edge sometimes.  2 gtags's advantage Today I tried the gtags source tagging system which provided by Gnu Global project.  It can pop up the minibuffer when multiple targets match the symbol, which functions let me felt much more comfortable. 3 gtags's disadv...

Configure emacs's auto-insert module Configure emacs's auto-insert module Table of Contents 1 how to use auto-insert? 2 Configure auto-insert-alist 1 how to use auto-insert? auto-insert mode is very useful, which can be used to declare the license in the header of the source code and some personal information, for example, who create this file and when? auto-insert will insert declaration according the variable named auto-insert-alist. It first search this variable and find the item match the file type, then extract the action to finish the auto insert. If you build an new elisp file buffer, and execute auto-insert command, it will insert the fantastic declaration with GPL license. But this command performs sucks in other mode like c-mode or python-mode. So you must configure variable auto-insert-alist by your self. 2 Configure auto-insert-alist I upload the source code into github, download according following a...

1. elisp's loading mechanisms In order to learn how to write an elisp package, you must be familiar with some ways of how to load your package to emacs. That means developers need to master following functions. Some of them puzzled me at  the past. Functions: load-file, load, require, autoload Following hyperlinks webpage removes my confusion, and give a good explanation of elisp's loading  mechanisms. http://ergoemacs.org/emacs/elisp_library_system.html?1352689199 Function Name Purpose Tech Detail Comment load-file Load a file. Load one specific file. Use this if you have one very SPECIFIC file at one particular file path. load Load a file. Load a file by searching thru var “load-path”. Also, tries to load a compiled version (.elc) if exists. Use this if the path for the file is not known in advance, and you are using a file name without full paths, such as “undo” or “undo.el”, and you want to load the compiled version if it exists (undo.elc). require Load a...

Emacs as an IDE works well with all kinds of the environment (C lisp elisp slime java python). But his auto-complete plugins sucks. I use hippie-expand before I met auto-complete. Auto-complete was the best auto-complete package in the present moment. This package is so simple that can be a tutorial on how to write a minor-mode package. And the users also easy to configure or modify it according to their needs. after a search in google, I add a package to use auto-complete in slime environment to develop a common lisp. Also, add a package to Let it search ac-source from etags files. I upload modified package into google drive: https://docs.google.com/open?id=0B5yiz3j-W7mca3VtYUpWTTl1VDg Install tutorial: 1. copy *.el to a directory like (~/.emacs.d/auto-complete/) 2. copy dict directory to a directiory like (~/.emacs.d/auto-complete/dict) change symbol ac-dictionary-directories according dict directory (add-to-list 'ac-dictionary-directories "~/.emacs.d/auto-com...

I find my emacs slow down after a long time operate in it.  Emacs process takes 50% of cpu resource. After search this problem in google, I found following stuff: http://ergoemacs.org/emacs/emacs_font_slowdown.html tabber-mode seems have bugs. So,  M-x tabbar-mode to disable tabber-mode, then everything become normal again.  Maybe I should disable tabber forever.
