Notepad++ is a free (as in "free speech" and also as in "free beer") source code editor and Notepad replacement that supports several programming languages and natural languages. Running in the MS Windows environment, its use is governed by GPL Licence.

Why another source editor?

" The company where I worked used JEXT (another open source code editor in Java) as the production tool. Due to its poor performance, I began an investigation to find another solution (in C++ instead of in Java) in September 2003. I found Scintilla and built a prototype. Unfortunately this solution was not accepted. I removed the specific part and continued to develop it in my leisure time. On the 25th November 2003 it was made available on Sourceforge, and that was the birth of Notepad++. "
