What is Emacs? Why should I use it?Įmacs is a text editing program with a very wide and powerful set of features. If you're interested in another editor, some internet research will likely turn up useful resources. You'll find our staff is generally most familiar with the mainstream emacs or vim, but you're welcome to use any editor that gets the job done for you. Emacs has been good to us but there are other good Unix text editors (vim, pico, gedit, and more). This guide covers the basics of using emacs to edit files. info files that are in the CAR of `Info-default-directory-list'.Written by Sarah Spikes, updated by David Philipson Just type: M-x ask-emacs (defun ask-emacs () The zgrep results in this case are nevertheless complete, and running the same commands in the terminal works perfectly without any error messages.

With some command-line utilities, Emacs may complain about exiting abnormally with code 1.

On OSX find/ xargs/ zgrep come pre-installed and they are located in the /usr/bin directory and, the car of Info-default-directory-list contains the built-in Emacs manual consisting of several. info files, the function includes a search for both. Inasmuch as zgrep can handle both gzipped and unzipped. In putting together the following function, I discovered that grep cannot see inside gizipped files, and not all versions of zgrep are able to search recursively. The following solution relies upon three (3) command-line utilities: find xargs and zgrep. With Icicles you also have an incremental way of getting apropos information about Emacs, available as part of the normal interaction with help commands (e.g. See, for example, (multi-)command icicle-doc, which gives you all the documentation that matches either symbol-names or doc-string input patterns, or both. If you use Icicles then you have more flexible apropos commands. In particular, there is command apropos-documentation. Type C-h f apropos TAB to see what they are, then C-h f for any of them to see more about them. Outside the manuals, the apropos commands are your friends.
In Info you can also search for a pattern across all installed manuals, using a (command info-apropos).
When you enter again using C-h i you re-enter where you left off, in the last manual visited. When you visit a manual using C-h r or C-h i you are in Info, a hypertext document reader. Index entries, on the other hand (which is what i searches), have been carefully chosen by Emacs developers and other users to represent what are typically the best entry points for the term you look up. This is because there are often plenty of occurrences of some search pattern that are not particularly relevant to what you are looking for. C-s) through a manual - i is your friend. In general, prefer i to searching full-text (e.g.
Once in a manual, you can also use incremental search, C-s or C-M-s, to search throughout the manual for literal text or a regexp match, respectively. Once in a manual, you can use i to search for index entries, with completion.
#Emacs manuals manuals#
The main manuals for Emacs are the Emacs (user) manual and the Elisp manual. C-h i takes you (initially) to all of the installed manuals, and from there you can choose a manual to visit.
I guess you mean the manuals? C-h r takes you to the Emacs manual.
