RXBuild

Run RXBuild in your browser
Github project page

Purpose

The goal is to provide a useful, crossplatform, light and free toolset for working with regular expressions. RXBuild is a bunch of javascripts and an html main page gluing them together.

Features

• Edit regular expressions

  • With snippets – to insert commonly used patterns
  • Insertion of escaped text – to match text litterally without caring about special characters
  • Token-list type regular expressions (such as \ba(bstract|s)|b(ase|ool|reak|yte)\b)
  • Have a quick reference readily available – I don’t know about you, but I really hate memorizing syntax.

• Analyse regular expressions

  • Easily test the expression against input text
  • Display the regular expression in english form (like a DOM)
  • Debug the regular expression (not done yet unfortunately)

• And use regular expressions

  • Export to a variety of programming languages, ready for pasting pleasure
  • Export to bash+grep

Run RXBuild

Simply open this link in your favorite browser (or Firefox). If you have a local copy of RXBuild, just open regex.html.

The page is divided in four parts:

• The top part is the sample input text – this lets you set and edit the text against which you test the regular expression
• The left part has the link to the quick-reference. I’m planning to put the analysers here
• The bottom part shows a tree with current matches for the expression
• The middle/main/right part is the regular expression itself. You use the buttons in the toolbar to edit it. At the far right of the buttons is the current cursor location

Source Code

The project’s source is hosted at http://github.com/ddlsmurf/qsqrcode

To do

The list of features that I intend to implement is in the github wiki todo page

Platforms

The code is tested only with Opera 9.6. Support for Firefox, Safari and IE7+ seems ok though.

Requirements

Should be independent at runtime, however, to build, you need at least JS/CC. The Makefile uses JSDoc to build the documentation and YUI Compressor to reduce the sources size

Compile Instructions

There is no need to compile, unless you are editing the parser’s grammar (src/regex_parser.par).

See the MakeFile. Update the paths in Makefile.user before hoping for anything.
