Editra

Editra is a cross-platform, open-source text editor, released under a wxWindows license. It is written by Cody Precord in Python, and it was first publicly released in June 2007. As of November 2011 the project is in alpha development phase, but "stable" builds are available for download. Editra has gained notability for being a text editor incorporated in Ren'py. The main site is down as of at least July 2019.
