Open Source Text/Programmer Editors

1. This list is not meant to be exahaustive. But relevant to our learning goals.
2. EMACS http://www.gnu.org/software/emacs/ "GNU Emacs is an extensible, customizable text editor – and more. At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing." The current stable release is 24.5 (April 2015)
3. Vi http://ex-vi.sourceforge.net/ The Traditional Vi Source Code for Modern Unix Systems
4. MS NotePad https://msdn.microsoft.com/en-us/library/vstudio/aa972157 "This sample is a full featured Windows Notepad application with some added features …"
5. MicroEmacs URL TBD
6. A quick to read review of "new style" editors named sublime-text, atom, brackets, light-table: http://www.sitepoint.com/sitepoint-smackdown-atom-vs-brackets-vs-light-table-vs-sublime-text/ "A new breed of editor has arrived. It fills the gaping void between basic text applications (Notepad, TextEdit, gedit, etc.) and full Integrated Development Environments (VisualStudio, Eclipse, NetBeans etc.) Simpler applications lack basic development requirements such as multiple documents, line numbering and code coloring. IDEs tend to be monolithic applications which cater for a specific language, framework or platform." … "Sorry Vi[m] and Emacs fans — console-based applications have been excluded" September 3, 2014

   Not by an academic. Certainly not thorough.
