Learn emacs (i) [Introduction to some commands and Emacs Lisp,list]

Like Linux, in the heart there is a desire to delve into the impulse of Linux. The idea is to be proficient with Emacs, and then use Emacs to work efficiently, read code, write programs, send and receive emails, and so on, but Emacs is not something that is as easy to use as Windows Word or VC.

I have learned before, but it was always intermittent, and did not always use its courage, but I still filled with this curiosity, there is a desire to overcome it, so every day I will spend one hours to read Emacs in the ready-made documents, all in English, read more slowly ...

Commands that are not commonly used
C-x s saves multiple buffers
M-x Replace string string, first enter the string you want to replace, and then enter a new string return
M-x recover file <return> restores files that have not been saved since the last unexpected exit, which is recorded in a file named "#...#" and automatically deletes files named "#...#" after recovery.

Envy VC or eclips above the automatic quick annotation function, Emacs also have, select an area (that is, place a tag mark in one position, then c-n or c-p to move the cursor elsewhere), and then
C-c C-c is M-x comment-region
The cancellation is like this:
M-x recomment-region

What is lisp and what is List
LISP = List Processing
List looks like this ' (Flower violet Daisy), enclosed in a pair of parentheses
They are separated by spaces, each of which is not separable, can be called "atoms", and the words that are quoted in double quotes are considered to be atoms.
If there is a quotation mark in front of the list, the list is not interpreted by the LISP interpreter
Before the list, if you don't quote, the first atom in the list often has a special meaning, and the Lisp interpreter explains that it performs some action, such as (+ 2 2), which will perform the actions of adding 2 and 2, and the first atom is called a function, and the following atom is the parameter of the function. Number

How to perform the list
The cursor moves to the end of the list, and then enter C-x c-e to execute the list in front of the cursor
Lisp interpreter explains 2 heavy entities, one is readable code, one is unreadable code, readable code is often stored in the. el file, unreadable code stored in the. ELC end of the file total

Message function
(message ' This message'll print at Echol window ')
(Buffer-name)
(message "This message print the buffer name%s" (buffer-name))
(Message "The value of the ' Fill-column is%d" fill-column)
