Free Programmer's Editors, Integrated Development Environment (IDE), ASCII Text Editors
This page lists free programmers' editors, Integrated Development Environment or IDEs, ASCII text editors or plain text editors, syntax highlighting code editors, and the like that are useful to programmers and web designers for writing the source code of a program or writing the HTML/PHP/Perl code for a website.
Note that certain specific types of editors have their own separate pages:
In addition, commercial programming editors like the EditPad Pro are not listed below.
Free Programmer's Editors, ASCII Text Editors (Plain Text Editors), Syntax Highlighting Editors
- Notetab Light
This is the freeware sibling of the commercial Notetab Standard and Notetab Pro. It has lots of features, and can handle multiple files up to 2GB in sizes, if your memory permits. One handy feature it has is the ability to display a tab for each document you have open under the toolbar, which makes it convenient if you are navigating around with a mouse. In spite of the fact that there is no source code syntax highlighting, it's one of my current favourites. This is a Windows editor. (Note: to get the free version, go to the "Download" page and look for "Notetab Light".)
