About the software
Pyreb is a wxPython GUI to the re python module; it will speed up the development of Python regular expression (similar to PCRE).
The GUI is simple and features 3 parts:

A text box where the text to be analyzed is displayed
A text box where the regular expression to be applied is displayed
A tree control where the results are displayed

Retest / Re-Try

Retest (And Re-Try), Test Python Regular Expressions In A Webbrowser

What Is It

A simple Server which enables tests of Python regular expressions ( re module) in a webbrowser. Uses SimpleHTTPServer and AJAX .

RE-TRY ONLINE APPLICATION

retest is now also available as re-try online application on GAE.

RETEST LOCAL BROWSER APPLICATION

retest is available to be run locally as a browser application.

retest screenshot:

You only need: Python , a modern webbrowser like Firefox, IE (from 5.5), Safari or Opera (from 8) which handlesXMLHttpRequest .

Download

retest-0.6.1 - 061224

Tested with Python 2.5, Firefox 1.06/2.0.0.1, Internet Explorer 6/7 and Opera 8.02/8.50 on Windows XP only. Seems to work best with Firefox and Opera, any feedback (success or failure ;) is welcome.

Paul Bissex reported retest working on OS X 10.4.3 (Python 2.4.1) in Safari, Camino, Opera, and Firefox. Bryon Gill reports retest working fine on Fedora Core 4, Python 2.4.1, Mozilla 1.7.10. James Thiele reports retest v0.5.1 works on OS X 10.3.9 Python 2.3. Erik Knowles reports retest working on Mandriva 10.1.

Usage

Start the server with >python reserver.py and open http://localhost:8087/ in your webbrowser (if the browser is not started automatically. You might want to adjust the PORT used in reserver.py.

The usage of the application itself should be self explanatory, take a look in the Python documentation for the re module .

Full keyboard usage is enabled. You may have to adjust the shortcuts to your browser or OS environment (e.g. on WindowsALT-T [in Firefox SHIFT-ALT-T ] puts the focus in the " T ext" field.). See the titles on the specific items for the keyboard shortcuts which are normally the underlined characters or, in the case of the size adjustment buttons, the characters1-6 .

Sometimes when you need to work on regular expression, you may need to look for a sandbox to do your testing. Here are two that I found quite helpful. Enjoy~~~
