This means Scintilla (the editor component in Notepad++, Geany, and others) is about 25. It was the foundation of my move away from proprietary editors like Visual SlickEdit, and served me well for more than a few years. I'm glad it's still around.
Same here. I used SciTE and Notepad++ way back in the day, probably 20-ish years ago. They were my first taste of useful light-ish weight text editors (with more features than plain old Notepad). Since then I no longer use windows as my daily driver and ended up settling on Vim, but I'm forever indebted to both SciTE and Notepad++ for opening my eyes.
Me, too! Use mostly Jetbrains these days, but we've been standing up some windows servers, and putting NPP on them - which reminded me of Scintilla: wrote my own turbo-charged IDE on top of it ~22 years ago. That secret sauce led to lots of work.
