Emacs Interact

How do you get user input (after displaying a prompt) in the command line?
One way is with (interactive), which is used to turn a function
into a command. As an example, look at

(defun irc-join (chan)
"join an IRC channel"
(interactive "sChannel to join: ")
(save-excursion
(setq irc-channel chan)
(irc-send-server (concat "JOIN " chan))))

Okay, what does this mean? When you want to define a function,
it begins with ‘defun’. Then next word, ‘irc-join’, is the name
of the function. Following that is ‘(chan)’, which is in
general the parameter list; this means that ‘chan’ is a
variable which is local to this function; if you want no parameters,
just put an empty list (). Following that is a description string
“join an IRC channel”; that string will show up whenever you do
M-x apropos on the function; that string is optional.
Finally, we get to the (interactive) part. What we are
concentrating on is the string: “sChannel to join: “, which has
a special format. The first character — ‘s’ in this case — specifies
the “type” of value to put in the first variable of the parameter
list. The character ‘s’ means “string”. So, now whenever somebody
calls your function with M-x irc-join, they would be prompted
to enter a string; the prompt will be “Channel to join: “. If you
wanted more parameters, it would be something like:


(defun function-name (stringparam numberparam)
(interactive "sPrompt here: \nnAnother prompt: ")
etc...

Note that each prompt string is separated by a newline character “\n”.
Also, ‘n’ means you want to get a number from the user. For more
info on these code characters, look under “defining commands”
section of the elisp docs.

You don’t necessarily have to use (interactive) to read in those
values, however. You could also do something like the following:


(defun irc-set-port ()
"set port number"
(interactive)
(let ((port
(read-string (concat "Port[" irc-port "]: ") "6667")))
(if (not (string-equal port ""))
(setq irc-port (string-to-number port)))))

This function has no parameters, and you notice (interactive)
also doesn’t have any prompt string. The main thing to look at
here is the ‘read-string’ function. This function takes one
argument which is a string for a prompt. Here I have shown a
little trick using the ‘concat’ function, which will let you
show a default value in the prompt.
You can find lots of information on functions like this by
using the apropos command: M-x apropos RET

Emacs Backup File Management

Set emacs so that all backups are directed into one folder:
(such as at a directory “~/myBackups”)

Use the following lisp code in init file:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
; return a backup file path of a give file path
; with full directory mirroring from a root dir
; non-existant dir will be created
(defun my-backup-file-name (fpath)Return a new file path of a given file path.
If the new path’s directories does not exist, create them.(let (backup-root bpath)
(setq backup-root “~/.emacs.d/emacs-backup”)
(setq bpath (concat backup-root fpath “~”))
(make-directory (file-name-directory bpath) bpath)
bpath
)
)
(setq make-backup-file-name-function ‘my-backup-file-name)

The above will mirror all directories at the given backup dir. For
example, if you are editing a file “/Users/jane/web/xyz/myfile.txt”,
and your backup root is “/Users/jane/.emacs.d/emacs-backup”, then the
backup will be at “/Users/jane/.emacs.d/emacs-backup/Users/jane/web/
xyz/myfile.txt~”.

If you want all backup to be flat in a dir, use the following:

1
(setq backup-directory-alist ‘((" . “~/.emacs.d/emacs-backup”)))

This will create backup files flat in the given dir, and the backup
file names will have “!” characters in place of the directory
separator. For example, if you are editing a file at “/Users/jane/web/
xyz/myfile.txt”, and your backup dir is set at “/Users/jane/.emacs.d/
emacs-backup”, then the backup file will be at: “/Users/jane/.emacs.d/
emacs-backup/Users!jane!web!emacs!myfile.txt~”. If you use long file
names or many nested dirs, this scheme will reach file name length
limit quickly.

C-x C-x exchange-mark-and-point Exchange mark and point, reactivating mark if required.
C-SPC set-mark-command Set and activate the mark, C-u C-SPC pops the mark ring.
C-x C-SPC pop-global-mark

A prefix of 0 (C-u 0) has a special meaning for the transpose family of functions. Since it would otherwise be meaningless
it transposes the chars/words/sexps/lines around the region specified by point and mark. It's best to try this one out to
see exactly how it works!

C-t transpose-chars
M-t transpose-words
C-M-t transpose-sexps
C-x C-t transpose-lines

** Mark and point can be treated as a rectangle, and are by certain functions. (see next section) **

==Rectangles
C-x r c clear-rectangle Replace text in the rectangle with spaces, blanking out the region destructively.
C-x r d delete-rectangle Delete text in the rectangle described by mark and point.
C-x r o open-rectangle Shift text in the rectangle right, blanking out the region non-destructively.
C-x r t string-rectangle Replace rectangle contents with the given string.
C-x r y yank-rectangle Yank back the last killed rectangle contents, top-left at point.

==Whitespace / cleaning up
C-x C-o delete-blank-lines Delete all but one of many consecutive blank lines.
fixup-whitespace Clean up space between objects around point.
M-\ delete-horizontal-space Delete all spaces & tabs around point.
M-SPC just-one-space Delete all spaces & tabs around point except for one (or N).
canonically-space-region Remove extra spaces between words in region.
delete-trailing-whitespace Delete all trailing whitespace in the current buffer.

==Shell mode
C-c C-n comint-next-prompt Move point to the next prompt.
C-c C-p comint-previous-prompt Move point to the previous prompt.
C-c RET comint-copy-old-input Copy the command input at point to the end of the buffer.

C-c M-d slime-disassemble-symbol Dissassemble the function definition of the symbol at point.

==Debugging

[TODO clean this up, this is copied from the Emacs wiki]

The following commands invoke restarts:

* 0 .. 9 - Invoke a restart by number.
* q - Throw to the top-level.
* a - Invoke the ABORT restart.
* c - Invoke the CONTINUE restart.

There are also commands for poking around in the frame at point:

* v - Show the current frame's source expression in a buffer.
* t - Toggle verbose display of the frame at point. The verbose version includes all local variables and CATCH tags.
* l - Show local variables.
* e - Evaluate an expression from inside a frame.
* d - Evaluate an expression and display the result in an extra buffer.
* i - Evaluate an expression and inspect the result.
* : - Evaluate an expression (in the global environment).
* D - Disassemble the code of the current frame.
* r - Restart execution of the frame with the same arguments as it was called originally. (Not supported by all backends.)
* R - Return a value from the current frame. (Not supported by all backends.)

Motion between frames:

* n - Move to the next frame.
* p - Move to the previous frame.
* M-n - Detail-move to the next frame. This switches the current frame to a one-line summary, then moves to the next frame, displays it verbosely in the backtrace (as with t), and shows the corresponding source expression (as with v).
* M-p - Detail-move to the previous frame.

==Reference
C-c < slime-who-calls Reveal callers of the function at or around point.
C-c > slime-who-references Reveal references to the global variable at or around point.

C-c C-d is the prefix for the following help commands:
d slime-describe-symbol Describe the symbol at point.
a slime-apropos
z slime-apropos-all Includes internal symbols.
p slime-apropos-package
h slime-hyperspec-lookup Customize with common-lisp-hyperspec-root browse-url-browser-function.
~ common-lisp-hyperspec-format

note:
now insert the opening and closing tags and sets point in between them. I have this bound to C-z t, as I use C-z as my personal command prefix.

< is bound to tagify-region-or-insert-self which really doesn’t warrant an explanation.

Adding a mode to emacs

How to add a new mode in gnu.emacs.help :

1. Put the .el file in the right directory.
2. Byte-compile the .el file, giving a .elc file which runs faster.
3. Put any setup stuff in ~/.emacs.

(1) Copy to right directory.

Type C-h v load-path RET to learn which directories are searched by
Emacs. A directory named site-lisp is for site-wide .el files and is
retained even after Emacs upgrades. If you don’t find a convenient
directory in this list, just add your own from ~/.emacs:

  (add-to-list 'load-path (expand-file-name "~/lisp/"))

The copy operation itself should be obvious :-)

(2) Byte-compile.

This one is easy: type M-x byte-compile-file RET, then enter the name
of the file (the copy in the site-lisp or ~/lisp directory or wherever
you put it).

(3) Setup stuff in ~/.emacs.

Usually, you will find a comment at the beginning of the .el file to
explain how to set it up. For matlab-mode.el, this does not seem to
be the case. Well, the easiest thing to do is to put the following
line in your .emacs file:

  (require 'matlab-mode)

Then, you can load a matlab file then type M-x matlab-mode RET to
enter the right mode. Or you can tell Emacs to automatically enter
matlab-mode for files with certain suffixes:

  (add-to-list 'auto-mode-alist '("\\.matlab\\'" . matlab-mode))

Or, you can put a line like the following in all matlab files:

  /* -*- matlab-mode -*- */

Before the first “-*-” and after the second “-*-” you can put any
text, such as the comment characters defined for the mode. I used C
comment characters in my example, but you can use the ones that are
right for matlab files.
