Pluma

Pluma is a small, but powerful text editor designed specifically for

the MATE desktop. It has most standard text editor functions and fully

supports international text in Unicode. Advanced features include syntax

highlighting and automatic indentation of source code, printing and editing

of multiple documents in one window.

Pluma is extensible through a plugin system, which currently includes

support for spell checking, comparing files, viewing CVS ChangeLogs, and

adjusting indentation levels.
