My Emacs Installation

Ubuntu 10.10
Emacs23

I have been using Vim for a long time. I often feel that the ESC key makes me very uncomfortable. I always need to press it so far. So I want to use Emacs and install Emacs first.

Apt-Get install Emacs

Oh, at least you can read the text and code. Then I looked at the code without a line number, so I was depressed. Find the solution on the Internet as follows:
Download linum. El
My content is as follows. You can also go online to the next one:
; Linum. El --- display line numbers to the left of Buffers

; Display line numbers for the current buffer. Copy linum. El to your

(Provide 'linum)
; Linum. El ends here

You can copy the file and name it linum. El.
I put linum. El in ~ /. Emacs. d/package/directory ,~ /. Emacs configuration is as follows:
; Displays the row number
(Add-to-list 'Load-path "~ /. Emacs. d/package ")
(Load "linum. El ")
(Require 'linum)
(Global-linum-mode 1)

In this way, the row number can be displayed. Haha, the first step is successful. Although I don't know the meaning of add-to-list and load-path, I will learn it later.

Then I found that when I used Emacs to input the. emacs file, I couldn't enter Chinese. That is the comment. It hurts again. If I don't have any Chinese Input, I will use a fart. Check it online.

I used scim, but I still feel full of it.
Scim installation becomes simpler and simpler. I used to perform the following two steps when I installed the blank Host:
Apt-Get install scim

Then add a file in the/etc/X11/xsession. d/directory, 95 xinput, and write the following content:
/Usr/bin/scim-d

Xmodifiers = "@ im = scim"
Export xmodifiers
Export gtk_im_module = scim

I found that I was wrong.

Emacs cannot directly call scim. It has not been solved for half a day. After finding scim-bridge, we can find it on the Wiki. Therefore, we have to go to these websites frequently in Linux, I directly paste the content I see:

Scimbridge Chinese

The scim-bridge.el is the scim-bridge client in GNU Emacs)

Scim-bridge.el can save the input states in different caches, so that you can quickly enter Chinese in Emacs, rather than switching the global input state repeatedly, very convenient.

What is scim?

Scim is a general-purpose smart Input Method platform that supports Chinese, Japanese, Korean, and many European languages. It can be used in POSIX operating systems, including Linux and BSD.
Install

* Install scim:
O In Debian, the steps are very simple:

Sudo aptitude install scim-bridge-Agent scim-bridge-client-GTK scim-bridge-client-qt4 scim-qtimm-y

O you can also use the following commands to install the "PinYin Input Method ":

Sudo aptitude install scim-pinyin-y

* Install scim-bridge.el:
O download the latest package from scim-bridge.el project in launchpad.
O enable Emacs to disable xim:
+ Add the following command ~ /. Xresources:

Emacs * usexim: false

+ Execute the following command to take effect:

Xrdb ~ /. Xresources

O add scim-bridge.el to load-path:
+ Decompress the scim-bridge package and place it in "~ /Elisp directory, and then add the following command ~ /. Emacs:

(Add-to-list 'Load-path (expand-file-name "~ /Elisp "))

O modify the switch key of scim:
+ The CTRL-Space key should be bound by Emacs by default. Therefore, you must add other keys in the scim graphic settings interface, such as super-space (other keys are also supported ).
O load and set the scim-bridge.el:
+ Add the following ~ /. Emacs:

; Load.
(Require 'scim-bridge-ZH-Si)
; If you use traditional Chinese, replace it with (require 'scim-bridge-ZH-Tr.
; Load ~ /. Automatically enable scim-mode after Emacs.
(Add-hook 'after-init-call' scim-mode-on)
; Set the input method switch key
(Scim-define-common-Key (KBD "s-SPC") T)
; Use the C-SPC as the markup command.
(Scim-define-common-Key (KBD "C-SPC") nil)
; Use C-/as the undo command.
(Scim-define-common-Key (KBD "C-\") nil)
; Set the cursor color in different input states.
(Setq scim-cursor-color '("red" "blue" "limegreen "))

Click suepr-space to enter Chinese.

Custom

* You can customize the scim-bridge.el in the following ways:

M-x Customize-group RET scim-bridge RET

I have translated relevant documents into simplified Chinese and Traditional Chinese, enjoy!

Step by step, the switch key of scim is changed to shift-space, and the others are exactly the same. Then, enable Emacs to switch the input method. Previously with those what lc_ctype = zh_CN.UTF-8 Emacs, you can pop up scim, The results only English, my grandmother, play more than no pop-up makes me a pain.

Now I can pop up the scim box, and it does have four words: intelligent pinyin. I was depressed and found that I can only enter Chinese characters. What about my days, it also makes people alive.
I went on to find a solution and found that this was not the case on the Internet. Many networks of my company's own machines were not accessible. We used remote clients. Inadvertently, when I used Firefox on the local machine for query (I usually don't need to access the Internet on the local machine), I found that I couldn't enter Chinese. I knew it was not an Emacs problem, but it was a problem with my scim, I saw someone on the internet saying that ibus can be used to input Chinese Characters in Emacs. I deleted scim and installed an ibus, in addition, if ibus-El cannot be found on our limited network, it will delete ibus again and reload scim. I almost betrayed it, but I finally came back. At this time, there was a problem, I don't know if I want to install scim-pinyin. When I first installed scim-pinyin, I wrapped it in by default, but this time he didn't install it for me and found this problem, I finally got it done.

Scim is okay, and Emacs is okay. My journey to Emacs is about to begin.
