Geany is a truly portable text editor. I used it own Windows, Linux, BSD and even Open Indiana. It could be compiled everywhere and run everywhere. This is what truly awesome about it. A comparison: TextAdept required Linux to compile and only cross compile to other platforms like these platforms are second class citizens, and now they are about to drop BSD support too.

As bad as they are, they still have LSP support: https://github.com/orbitalquark/textadept-lsp
