![]() Searching and replacing across pages of code when using in an IDE such as Visual Studio, Komodo IDE or even Dreamweaver's crippled ECMAScript flavor.Ĥ. I use regex to rename files, to search in files, to make large-scale substitutions in code, in code (PHP), with databases (mySQL) and to direct my web server (Apache).ģ. In the result window, the results change instantaneously as you tweak the expression, much as in RegexBuddy. It does one job, and does it brilliantly: searching for and replacing text in a file, or many files at once. Still, a ten-year-old PCRE is a lot better than JavaScript.įor replacement in text files, I love ABA Replace. This means that a lot of juicy features are missing. What they don't say is that the PCRE version they use is 4.0 from 17 February 2003-or so it appears to me, as it supports from 4.0 but not \X from 5.0. On OSX, the free TextWrangler its big brother BBEdit both claim to use PCRE. The free Notepad++ used to be deficient in the regex department, but since version 6, it has been using the excellent PCRE engine-though the interface is still clunky.

On this page, we'll first look at a number of contexts and programs where you may find regex. Once you learn it, you discover it comes in handy in many places where you hadn't planned to use it. I have not yet had time to revise this page, so please be aware that it is not up the same standard as most pages in the tutorial. If this post was useful, Say thanks with a coffee.August 2014: Lately I've added many new regex pages and been making major overhauls to old ones. Big thanks to Matt Martini (the original Language Module author) and Ray Hatfield for their efforts. Job done – you should now have code folding and syntax highlighting in BBEdit 10. Then add a ‘Custom Extensions Mapping’ (enter ‘scss’as the suffix and use the selector on the right to choose ‘SASS’) and restart BBEdit 10. So, go get the file here: and save it into ~/Library/Application Support/BBEdit/Language Modules (if that doesn’t work, you can go the riskier option of saving it in BBEdit.app (you’ll need to show package contents) > Contents > Language Modules) and then in BBedit, go to the preferences panel and go to the languages section.
