The GUI is made with Qt, for which the preferred programming language is C++. So that could be one reason already. There are a lot of bindings listed for Rust in the Qt docs [1] though, but they will always be a subpar experience compared to the first-class support for C++ in Qt.

Yeah and the main editing component is Scintilla, also C++.

an electron implementation would sorta kill the point of npp :)

Absolutely, the startup speed of npp is addictive. If only VS Code could be half as fast.

that's the main reason I stuck with sublimetext for soooo long. It's so fast and it can handle insanely huge files plus it can do column operations on text on insanely huge files. VS Code does seem to have been optimized since the first few years though and its not hardware related.

I was thinking the same thing. Why didn't they do it in Rust? But probably because the GUI story with Rust is still evolving. Only recently have I started to see UI frameworks popping up for Rust.
