How does this convenient format looks like, in your mind? The grammar = definition is already the =E2=80=9Csource=E2=80=9D, I don=E2=80=99t see = a way to magically make it easier to work with. What does =E2=80=9Cmanual = updates=E2=80=9D refer to? If you mean updating patterns like (init_declarator declarator: (identifier) @font-lock-variable-name-face) (parameter_declaration declarator: (identifier) @font-lock-variable-name-face) when a language=E2=80=99s grammar changes, I don=E2=80=99t think we need = to update them often, or ever. And It is not harder than updating = font-lock-keywords when a language adds a new fancy syntax. Yuan=
