Komodo Edit

Komodo Edit is free and open-source IDE that offers support for a wide range of programming and scripting languages, such as PHP, Python, Ruby, Tcl, Perl, JavaScript, CSS, HTML, RHTML, and others. It offers support for syntax highlighting and macros, among others.

Wrapped up in a comfortable-looking interface, the tool invites you to start a new project by opening files or creating them from scratch.

It features a spellchecker and samples with abbreviations (e.g. PHP, Ruby), predefined blocks of HTML code, macros for creating directory shortcuts, a file searcher, and others.

You can explore Ruby tools (e.g. generators, migrate, plugins, snippets, plugins), run tests, create or delete databases, manage files within the project, or disable notifications when recording macros.

It's possible to turn a single line or a group of lines into a comment, change the paragraph alignment, join lines, increase or decrease the font size, create bookmarks, preview webpages in the default browser, save templates, use command-line operations for editing and debugging files, view the hierarchical code structure within a file, as well as build, edit, or debug regular expressions.

Everything worked smoothly in our tests, thanks to the fact that the app didn't hang, crash or display error messages. Although CPU consumption was low, RAM usage was pretty high, so those running Windows on machines with weaker hardware are likely to experience issues.

Komodo Edit has some handy options under its hood that are geared at experienced programmers, so you can definitely check it out, especially when taking into account that it's free.
