I am looking for Notepad++-like source code editor with built-in Command prompt. I did not like NppExec plugin for Notepad++ because it uses its own scripting language.
I am looking for something like Embedded Terminal feature in Gedit on Linux.
There is a version of Gedit for Windows; however, this version doesn't have Embedded Terminal plugin or anything like this.
Take a look at jEdit, it has a built-in terminal and lots of useful plugins. The downside (for some) is that it's Java based, but it's very responsive and can be made to look rather native.
