Scintillua enables Scintilla lexers to be written in Lua, particularly using LPeg. It can also be used as a standalone Lua library for syntax highlighting support.
Scintillua 6.0 considers lexers from Scintillua 5.x to be legacy lexers. While legacy lexers should still function properly, they ought to be migrated using this migration guide.
In addition to the steps outlined in the migration guide, programming language lexers should ideally distinguish between functions, builtin functions, and methods. They should also distinguish between constants and builtin constants, and variables and builtin variables. For example, the Lua lexer does so here and here. The Makefile lexer does so here.
Lexers that use custom tokens should try and pick from the updated list of tags. If that is not possible/reasonable, it may be worth considering adding to that list. Otherwise, it should remain a custom tag name and a style should be set for it for all themes in themes/. That will signal that applications will need to add styling for it.
The following unchecked Scintillua lexers still need to be migrated:
