Programmer's Notepad 

Programmer's Notepad is an open-source text editor that I found to be very similar to the more popular Notepad++. In addition to basic text editing tools, it also offers many features that are especially useful for programmers, software testers, etc. It is a small application that runs on all the popular Windows versions.

Programmer’s Notepad offers an easy way of editing source code that was written in programming languages like: C / C++, Assembler, C#, PHP, MatLAB, Pascal, Perl, Verilog, Javascript and Java, as well as many others. Although this is not a tool that will develop applications and test them, it proves to be useful when you need to edit a certain piece of code, and opening a powerful IDE like Visual Studio is quite system resource consuming in that situation.

I was surprised to see the great number of improvements that this version of Programmer’s Notepad comes with. Most of them are requests submitted by other users of this application. In addition to many interface enhancements, Programmer’s Notepad focuses on providing correct schemes for each of the supported programming languages. Also, a lot of bugs have been fixed in version 2.3 of the application.

Although, there are other popular open-source text editors like Notepad++ and AkelPad, Programmer’s Notepad stands as a great alternative to them.
