Smultron

Smultron is an open source text editor for programmers that comes with a few interesting features, among them: syntax highlighting in several languages and the autocomplete function.

The viewing of documents is another of Smultron’s strengths. With it, you can view a document on full-screen, split the editor into two parts, or view it separately. Documents can be organized by projects and separated using tabs on the program’s interface.

The 'commands' function on Smultron lets you run operations from the program’s very own interface. You can also use this function to save the parts of code which you use most frequently.
