| Perl and PHP Regular Expressions | |
| PHP regexes are based on the PCRE (Perl-Compatible Regular Expressions), so any regexp that works for one should be compatible with the other or any other language that makes use of the PCRE format. Here are some commonly needed regular expressions for both PHP and Perl. Each regex will be in string format and will include delimiters. | |
| All Major Credit Cards | |
| This regular expression will validate all major credit cards: American Express (Amex), Discover, Mastercard, and Visa. | |

| SCM Post-Commit Message Syntax | |
| To associate an SCM commit with a specific Tracker story, you must include a special syntax in the commit message to indicate one or more story IDs and (optionally) a state change for the story. Your commit message should have square brackets containing a hash mark followed by the story ID. If a story was not already started (it was in the "not started" state), a commit message will automatically start it. For example, if Scotty uses the following message when committing SCM revision 54321: | |
| [#12345677 #12345678] Diverting power from warp drive to torpedoes. | |
| # Mac OS X Lion introduced a new, iOS-like context menu when you press and hold a key | |
| # that enables you to choose a character from a menu of options. If you are on Lion | |
| # try it by pressing and holding down 'e' in any app that uses the default NSTextField | |
| # for input. | |
| # | |
| # It's a nice feature and continues the blending of Mac OS X and iOS features. However, | |
| # it's a nightmare to deal with in Sublime Text if you're running Vintage (Vim) mode, | |
| # as it means you cannot press and hold h/j/k/l to move through your file. You have | |
| # to repeatedly press the keys to navigate. |

#Node - Processes
To launch an external shell command or executable file you can use the child_process. Apart from command line arguments and environment variables you cannot communicate with the process using child_process.exec. However you can use child_process.spawn to create a more integrated processes.
##Executing Child Processes
###To launch an external shell command
var child_process = require('child_process');
var exec = child_process.exec;
| #!/bin/bash | |
| # Functions ============================================== | |
| # return 1 if global command line program installed, else 0 | |
| # example | |
| # echo "node: $(program_is_installed node)" | |
| function program_is_installed { | |
| # set to 1 initially | |

Let's have some command-line fun with curl, [jq][1], and the [new GitHub Search API][2].
Today we're looking for:
