Emacs configuration of mine

Emacs configuration of mine

This is my emacs configuration for learning emacs.

I have only used it on Archlinux distro, however, it should be supported by other linux distributions.

Quick Start

Backup yours emacs configure files like ~/.emacs, ~/.emacs.d.

Clone it to your $HOME/.emacs.d:

git clone  https://github.com/Zexi/emacs.d.git ~/.emacs.d

Then just start your emacs editor, which will auto download required packages and build them.

Features

• Use GTAGS to view source code, which support kinds of languages
• Auto complete source code
• Helm frame support
• Work session restore
• Dictionary support
• Lots of theme to select

Usage

View kinds of source code

1. Install dependent packages for generate GTAGS for kinds of languages

$ yaourt -Ss global ctags pygmentize

2. Enter your project directory and generate GTAGS use ctags or pygments

$ gtags --gtagslabel=ctags --debug			# use ctags
$ gtags gtags --gtagslabel=pygments --debug	# use pygments

3. View source code in Emacs through helm-gtags

Command	Action
C-c g a	Show tag names which are referenced in this function and jump to them.
C-j	Tag jump using gtags and helm
M-t	Input tag name and move to the definition
M-r	Input tag name and move to the referenced point
M-s	Input symbol and move to the locations
M-.	Find name by context
M-,	Move to previous point on the stack
C-c <	Move to previous history on the context stack
C-c >	Move to next history on context stack

Complete source code

Use company-mode to complete kinds of languages

• C/C++: use irony-mode and company-irony
• Ruby: use robe
• Python: jedi
• Latex: auctex and company-auctex
• Emacs Lisp & others: company-mode backends

Helm frame

Use Helm frame by default, which will make enter command more easily.

• Bind the traditional C-x C-f to helm-find-files by default. You should use C-l to go to the precedent directory level instead of DEL
• Bind M-x to helm-M-x I'm go on learning it, see emacs-helm for more details.

Work session restore

This is a convenient function which will save your last work session and restore them when you next start emacs. If you want to cancel this, just comment (require 'init-session') line in ~/.emacs.d/init.el.

Dictionary support

This is a useful function when you want to search some words in emacs.

1. To enable this feature, you should install dictd.

$ yaourt -S dictd
# Then download some dictionaries and edit '/etc/dict/dictd.conf' to index them
$ systemctl start dictd.service # start dictd service
$ systemctl enable dictd.service # if you want to start this serive when boot

2. Search words in emacs, use dictionary package

• Search word definition: C-c d
• Enter word to search: C-c s
• Dictionary match words: C-c m

Select theme you like

Lots of theme will be installed when first start emacs, you can chose one you like. See this gallery:

• monokai-theme
• color-theme-sanityinc-tomorrow
• cherry-blossom-theme
• busybee-theme
• gruber-darker-theme
• afternoon-theme
• cyberpunk-theme
• moe-theme
• alect-themes
• ample-theme

Use M-x load-theme, then chose one and try.

Other misc packages

• window-numbering-mode: use M-[0-9] to quick change window
• smart-compile: use smart-compile to compile c\c++ code
• w3m view web pages: it's simple configure file can be found in ~/.emacs.d/lisp/init-w3m.el

Configuration file structure

File in '.emacs.d/init.el' bootstraps the configuration.
Other config files are placed in 'lisp/init-*.el', and required packages will be downloaded at first boot.
