Help me, Help you

Make this setup better if you find it useful.

Warning

If you are a newbie and want to use Emacs immediately, please check the section “Install stable version in easiest way”.
Emacs newer than the version 24.3.93.1 are NOT supported.
I use Vim key bindings. Check section Tips if you prefer Emacs key bindings.
People in Mainland China need goagent to download packages. Run command “http_proxy=http://127.0.0.1:8087 emacs -nw” in shell after starting goagent server (or any proxy server).
C++ developers need tell Emacs location of header files. Please check see section `clang`.
Windows users could use Emacs in Cygwin to avoid instaling other GNU tools. But this setup is still usable in native windows version if you set up environment variable HOME.
My priority is make this setup stable. So I whitelist packages from melpa (melpa-unstable, actually). It means by default packages from melpa-unstable are invisible. Modify variable “melpa-include-packages” in init-elpa.el if you want to install some package from melpa-unstable.
In the bug report, please include environment details (OS, Emacs version …) and the full output of `emacs –debug-init`.
If a package is at myelpa, you can place its code at ~/.emacs.d/site-lisp. There are already some samples there.
Remove bundled emacs 22 at first if you are using OS X!

General

Most popular languages are supported (C/C++/Java/Ruby/Perl/Python/C#/Lua/Javascript …).

Please contact the original developer if you don’t know how to set up a package. EmacsWiki also has all the tips.

A short tutorial for newbie is provided at section Emacs quick guide.

If you need a detailed guide, check my Mastering Emacs in one year.

Install

If you prefer the method described in the section “Install stable version in easiest way”, you don’t need read this section..

Please remove the file “$HOME/.emacs”.

Uninstall any system Emacs plugins. For example, run “apt-get uninstall emacs-w3m” in Debian/Ubuntu to remove emacs-w3m. It’s because all plugins will be placed at “$HOME/.emacs.d” from now on.

Download this zip file and extract its content into ~/.emacs.d .

Or run command “cd ~; git clone https://github.com/redguardtoo/emacs.d.git .emacs.d” in terminal.

Ensure that the init.el contained in this repo ends up at ~/.emacs.d/init.el.

You possibly need run below command at the terminal at least once to update the content from package repositories:

emacs -nw --batch -l ~/.emacs.d/init.el -f package-refresh-contents

The command “package-refresh-content” will fetch the latest package list from remote servers. It has to be done manually. It’s not reasonable to automatically fetch the list for a normal text editor.

Emacs quick guide

Step 1, Learn OS basics

Know what is environment variable
Know what is pipe, stdout, stdin

Step 2, Read official tutorial at least once

Press “C-h t” (C means Ctrl) and start read tutorial.

Know how to move cursor
Know how to open help. Press “C-h v” and “C-h f”.

Step 3, Know org-mode basics

Org-mode is a for notes-keeping and planning. Please watch the Carsten Dominik’s talk. It’s really simple. The only hot key you need remember is “Tab”.

Step 4, Solve your first specific problem

For that specific problem, you can visit EmacsWiki for the solution. Newbies can ask for help on http://www.reddit.com/r/emacs/.

Directory structure

init.el is main file which include all the other *.el files.

“lisp/init-elpa.el” define how and what packages will be installed from elpa/marmalade/melpa by package manager.

The package manager will extract packages into ~/.emacs.d/elpa/.

I also manually download and extract some packages into ~/.emacs.d/site-lisp/. Packages in ~/.emacs.d/site-lisp/ is not visible to Emacs package manager.

My own snippets for Yasnippet is in ~/.emacs.d/snippets.

Other directoris do not matter.

Third party command line tools

They are OPTIONAL. Your Emacs will not crash if they are not installed.

w3m (web browser in console)

needed by `w3m` (w3m is emacs package name written in elisp)
install through OS package manager
please note only emacs with GUI can display image

lua

required by `flymake-lua`
install through OS package manager

aspell or hunspell

needed by `flyspell`
hunspell is the alternative of `aspell`. So you need only one of them.
install through OS package manager
for aspell, you may need its dictionary like aspell-en
I force the dictionary to “en_US” in init-spelling.el. You can modify it in init-spelling.el.
I recommend aspell for programmers

sbcl (lisp environment)

needed by lisp `slime`
install through OS package manager

tidy or html5-tidy

needed by `web-mode` for real time HTML syntax check
install through OS package manager
For html5-tidy, you need download its source code and build it manually
I recommend html5-tidy because it supports html5

csslint

install `node.js` through OS package manager, then `sudo npm install -g csslint`

zip and unzip

needed by `org-mode` to export org file to odt file
install through OS package manager

jshint

install `node.js` through OS package manager, then `sudo npm install -g jshint`
required by js-mode
by default I use js2-mode which does NOT need jshint

xsel

needed by my clipboard command `copy-to-x-clipboard` and `paste-from-x-clipboard` under Linux
install through OS package manager

CMake

needed by `cpputils-cmake`
install through OS package manager
Please use out-of-source build tree when using CMake

Clang

needed by `cpputils-cmake`, `company-clang`
install through OS package manager
If you use `cpputils-cmake` and `cmake`, `cpputils-cmake` will do all the setup for you. You don’t need read next item! But please spend a few minutes to learn the basics of cmake! There is a one minute step-by-step-guide in README of cpputils-cmake to teach you how to use cmake.
If you use `company-clang`, add `(setq company-clang-arguments ‘(“-I/example1/dir” “-I/example2/dir”))` into ~/.emacs.d/init.el

GCC/Make

needed by `flymake`
install through OS package manager

MozRepl (Firefox addon)

needed by MozRepl
used by Firefox

CTags

it creates tags file for code navigation
needed by many tags related plugins
install through OS package manager
See How to use ctags in Emacs effectively if you prefer my way

GNU Global

needed by `ggtags.el`
it creates index files for code navigation
more advanced than ctags, supports references and better performance
install through OS package manager

pyflakes

You need pyflakes for real time python syntax checker like `flymake-python`
Install pip through OS package manager, then `pip install pyflakes`
On cygwin you need install `setuptool` in order to install `pip`.

libreoffice

Only one executable `soffice` needed when converting odt file into doc (Microsoft Word 97)
conversion will happen automatically when exporting org-mode to odt
The conversion command is in variable `org-export-odt-convert-processes`
Install through OS package manager

js-beautify

To beautify javascript code (insert extra space, for example)
Install pip through OS package manager, then `pip install jsbeautifier`

What is “OS package manager”

apt-cyg at Cygwin
homebrew at Mac
any package manager at Linux (apt-get at Ubuntu, yum at Redhat, pacman at Arch, emerge at Gentoo …)

Install stable version in easiest way

You don’t need git or network any more. All you need are only two zip files.

Here are the exact steps you need follow:

Remove the file “~/.emacs”.
Uninstall any system Emacs plugins. For example, run “apt-get uninstall emacs-w3m” in Debian/Ubuntu to remove emacs-w3m. It’s because all plugins will be placed at “$HOME/.emacs.d” from now on.
Download https://github.com/redguardtoo/emacs.d/archive/v1.1.zip
Extract its content into empty directory “~/.emacs.d” (“~” means HOME directory). After extraction, there will be a file named “init.el” in “~/.emacs.d”
Download https://github.com/redguardtoo/myelpa/archive/v1.1.zip
Extract the zip somewhere, say “~/myelpa”.
Double check that there is a file named “archive-contents” in the directory “~/myelpa”
Uncomment below code in ~/.emacs.d/init-elpa.el and start Emacs now!

(setq package-archives '(("myelpa" . "~/myelpa/")))

That’s it. You will never need internet in the future. I tested it on Emacs 24.3.93.1, Emacs 24.3.1 and Emacs 23.4.

Please note that your packages are locked. So you cannot upgrade package online in the future unless you comment out above code line.

I don’t recommend advanced users locking their packages.

Report bug

Please file bug report at https://github.com/redguardtoo/emacs.d. Don’t email me directly!

Tips

By default EVIL (Vim emulation in Emacs) is used. You can comment out line containing “(require ‘init-evil)” in init.el to unload it.

Some package cannot be downloaded automatically because of network problem.

You need manually `M-x list-packages` and install it or just `M-x package-refresh-content` and restart Emacs.

If you use `gnus` for email (Gmail, for example). Check ~/.emacs.d/init-gnus.el which includes my most settings except my private stuff. Here is my Gnus tutorial.

To toggle Chinese input method (eim, for example), run command `M-x toggle-input-method`.

FAQ

Please contact the original plugin developer if you find any plugin bug. My answer may be outdated soon.

Why auto-completion/intellisense does not work?

I assume you use company-mode. Other plugins have similar setup.

At minimum:

You need install clang
Make sure your code is syntax correct at the beginning
assign reasonable value into company-clang-arguments

Here is sample setup in ~/.emacs:

(setq company-clang-arguments '("-I/home/myname/projs/test-cmake" "-I/home/myname/projs/test-cmake/inc"))

In “friendly” Visual C++, you need do similar setup.

Use color theme in the terminal

TERM=xterm-256color emacs -nw

Avoid Emacs maximized when it starts up

Comment out below line in init-misc.el:

(add-hook 'window-setup-hook 'maximize-frame t)

Preview&apply a color theme?

Check http://emacsthemes.caisah.info/.

Write down the name of color theme (for example, molokai).

Insert below code into ~/.emacs.d/init.el,

(require 'color-theme-molokai)
(color-theme-molokai)

“M-x color-theme-select” may not work in this setup. It’s because there is some design flaw in Emacs.

My personal custom.el (OPTIONAL)

It’s publicized at http://blog.binchen.org/?p=430. It contains my personal stuff which is useless to you.
