download

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 Windows ALT-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 characters 1-6 .
