As its name implies, the venerable Notepad++ text editor began as a more capable version of the classic Windows Notepad, with features such as line numbering and syntax highlighting. It was created in 2003 by Don Ho, who continues to be its primary author and maintainer, and it has been a Windows-exclusive app throughout its existence (older Notepad++ versions support OSes as old as Windows 95; the current version officially supports everything going back to Windows 7).
I'm not a devoted user of the app, but I was aware of its history, which is why I was surprised to see news of a "Notepad++ for Mac" port making the rounds last week, as though it were a port of the original available from the Notepad++ website.
Apparently, this news surprised Ho as well, who claims that the Mac version and its author, Andrey Letov, are "using the Notepad++ trademark (the name) without permission."
