My programmer’s editor of choice for quite a while now has been Zend Studio 5.5, it has many useful tools like built-in function reference and code completion. It allows you to create your own colour schemes (unlike the new Zend Studio 6) and debug code.

As a secondary editor i would use Gedit on linux and Context on Windows. Every now and again i take a look at what editors are available as oftern the editor a developer uses is a matter of personal taste.

Not long ago I came across the open-komodo project, which provides a free multi-platform version of the Komodo IDE as the text editor Komodo Edit, and I love it.

Komodo Edit has dynamic language support for Perl, PHP, Python, Ruby, Tcl, JavaScript, CSS, HTML, and XML, it also supports template languages like RHTML, Template-Toolkit, HTML-Smarty and Django.

Komodo Edit has many of the tools that I like about Zend Studio, such as code auto-completion and calltips, multi-language file support (great!), syntax coloring and syntax checking, Vi emulation, Emacs key bindings!

What more could you as from an open source editor? What’s that? you want more? How about firefox like extensability? The open komodo community has a wealth of extensions for the editor from Mootools API to jQuery tools. Check it out, I hope you likeit as much as I do.
