TextEdit is a pretty complete open source word processor and text editor that can handle documents in HTML, CSS, JavaScript, PHP, PERL, SQL, Delphi, C, and C , among others.

Apart from this wide range of supported language source codes, TextEdit incorporates several tools that are very useful for daily work with templates and text.

Among the options offered, one of the best is being able to work with tabs, which come with a visualization system that makes switching between tabs much easier.

You can also find tools that help you add markers, comments, work with fragments or lines of text, and the all-important search engine and chain text replacement tool that you will not miss out on with TextEdit.
