Regexp

2013-01-27T04:21:25Z

Pogin: Add foreign-regexp.el Link

== Origin ==

'''Regexp''' is a portmanteau of the words '''regular''' and '''expression'''. It is the Emacs abbreviation for "regular expression".
Many other computer languages and software use the abbreviation '''regex''' (no trailing p) instead.

Wikipedia has a nice article about [http://en.wikipedia.org/wiki/Regular_expression regular expressions] in general. This article focuses on the Emacs Lisp implementation of regular expressions.

== Syntax ==

The following characters are special : . * + ? ^ $ \ [

Between brackets [], the following are special : ] - ^

Many characters are special when they follow a backslash – see below.

. any character (but newline)
* previous character or group, repeated 0 or more time
+ previous character or group, repeated 1 or more time
? previous character or group, repeated 0 or 1 time
^ start of line
$ end of line
[...] any character between brackets
[^..] any character not in the brackets
[a-z] any character between a and z
\ prevents interpretation of following special char
\| or
\w word constituent
\b word boundary
\sc character with c syntax (e.g. \s- for whitespace char)
 start\end of group
\< \> start\end of word
\` \' start\end of buffer
\1 string matched by the first group
\n string matched by the nth group
\{3\} previous character or group, repeated 3 times
\{3,\} previous character or group, repeated 3 or more times
\{3,6\} previous character or group, repeated 3 to 6 times
.?, +?, and ?? are non-greedy versions of ., +, and ?
\W, \B, and \Sc match any character that does not match \w, \b, and \sc

=== Character category ===

\ca ascii character
\Ca non-ascii character (newline included)
\cl latin character
\cg greek character

=== POSIX character classes ===

[:digit:] a digit, same as [0-9]
[:upper:] a letter in uppercase
[:space:] a whitespace character, as defined by the syntax table
[:xdigit:] an hexadecimal digit
[:cntrl:] a control character
[:ascii:] an ascii character

=== Syntax classes ===

\s- whitespace character \s/ character quote character
\sw word constituent \s$ paired delimiter
\s_ symbol constituent \s' expression prefix
\s. punctuation character \s< comment starter
\s( open delimiter character \s> comment ender
\s) close delimiter character \s! generic comment delimiter
\s" string quote character \s| generic string delimiter
\s\ escape character

=== Embed Emacs Lisp ===

\,expr where expr is an Emacs Lisp expression.

This is mostly used in the replace part of the regexp. Like this:

$foo$$bar$ -> \1\,(upcase \2)
foobar -> fooBAR

|-
|lgrep

|-

|-
|dired-do-rename-regexp

|-
|find-grep-dired
|display files containing matches for regexp with Dired
|}

== Tips and Tricks ==

To enter a '''newline''' character in a regexp, use the two keystroke sequence '''C-q C-j'''.
It will appear in the minibuffer as '''^J'''.

== ruby-mode ==

'''{{ModeLink|ruby-mode}}''' provides basic font-locking, indentation and navigation support for Ruby source code. It was first included in Emacs 23 (previously it was a third party package, maintained by Ruby's developers). While {{Mode|ruby-mode}} is fairly barebone package it could be augmented by a multitude of minor modes such as [http://github.com/rejeep/ruby-end ruby-end], ...

=== Ruby on Rails ===

==== [[Rinari]] ====

Rinari stands for Rinari Is Not A Rails IDE. It is an Emacs minor mode for Rails that is actively maintained. For best results install it from the [https://github.com/eschulte/rinari git repo].

The official documentation is alright, but for best information check out the source. It allows for 'jumps' between Model, View, Controller and their RSpec examples and Test Unit tests, as well as Cucumber steps and features.

Also, it allows for the running of a console session with full Rails application loaded for interactive use, SQL console, starting of the web server (rails server).

Ecukes

Pogin: Modify Ert Link

{{Package
|name=Ecukes
|description=Cucumber for Emacs
|author=Johan Andersson
|maintainer=Johan Andersson
|source=https://github.com/rejeep/ecukes
}}

There are plenty of unit/regression testing tools for Emacs, and even some for functional testing. What Emacs is missing though is a really good testing framework for integration testing. This is where '''Ecukes''' comes in.

Cucumber is a great integration testing tool, used mostly for testing web applications. Ecukes is Cucumber for Emacs. No, it's not a major mode to edit feature files (see [[feature-mode]] for that). It is a package that makes it possible to write Cucumber like tests for your Emacs packages.

Emacs Starter Kit

2013-01-27T02:31:51Z

Pogin:

{{Package
|name=Emacs Starter Kit
|description=Starter Kit
|maintainer=Phil Hagelberg
|source=https://github.com/technomancy/emacs-starter-kit
}}

The '''Starter Kit''' provides a more pleasant set of defaults than you get normally with Emacs. It was originally intended for beginners, but it offers a nicely augmented working environment for anyone using Emacs.

= Basic setup =

You'll need Emacs 24, which comes with package.el. It's not hard to compile from source, but precompiled versions are readily available for Debian-based systems, Mac OS X, and Windows.

If you need to maintain compatibility with Emacs 23 or 22, you need to use version 1.

Add Marmalade as a package archive source in ~/.emacs.d/init.el:

{{Snippet|
(require 'package)
(add-to-list 'package-archives
'("marmalade" . "http://marmalade-repo.org/packages/") t)
(package-initialize)
}}

Evaluate that code by hitting {{Command|eval-buffer}} in {{Filename|init.el}}, then you can install it:

{{Command|package-refresh-contents}}

{{Command|package-install RET starter-kit RET}}

Pogin: Add category

Gnu Privacy Guard is GNU project's complete and free implementation of the OpenPGP standard. you can:
* Encrypt and Decrypt files
* Signing and Checking signatures

== EasyPG ==
[[EasyPG]] is an all-in-one GnuPG interface for Emacs. It consists of two parts: EasyPG Assistant and EasyPG Library.

* EasyPG Assistant is a set of convenient tools to use GnuPG from Emacs.
* EasyPG Library is a sort of an elisp port of GPGME, a wrapper library which provides API to access some of the GnuPG functions.
