FontForge comes with two scripting systems - largely-regular Python and an unnamed scripting language that uses the extension .PE.
While the documentation advices to prefer Python scripting where possible, it is still nice to be able to read the existing PE scripts easier.
This User Defined Language for Notepad++ aids with that, adding folding and syntax highlighting for built-in functions and variables of the scripting language.
Originally I made this UDL sometime around 2015 when I started working on pixel art fonts and found that my "pipeline" (pixel art editor -> custom tool -> BitFontMaker2 -> TTF file) commonly required series of post-fixes to accomplish correct line height / spacing / rendering.Fast-forward to 2019, I'm moving files to the new computer and realize that I never published this UDL. So, here you go:
Alternatively, here's the entirety of that:
