Komodo Edit

Komodo Edit is an integrated, multi-platform and multi-language development environment for the creation of dynamic web applications.

It includes the basic functions that can normally be found in these types of programs, including autocomplete, syntax checking, and language highlighting.

Komodo Edit has been created to work with dynamic languages such as PHP, Ruby, Perl, Python y TCL; it will also allow you to work with XML, HTML, Javascript and CSS.

The app makes use of 'calltips', which are pull-down menus that allow you to select the attributes of the different labels while editing the code. Additionally, the extension system of Komodo Edit is identical to the one which can be found in Firefox.
