Highlight postulates and assumptions distinctly, by severity - #77
Merged
Conversation
The language server marks #postulate and #assume names with standard semantic token modifiers, at the declaration and at every use site. Map them to TextMate scopes for the rzk languages, in decreasing order of severity: - function.abstract.static (#postulate, a permanent axiom) -> invalid: error red in essentially every theme; - function.abstract (top-level #assume, a file-wide axiom) -> string.regexp: the same reddish colour as holes; - parameter.abstract (#assume inside a #section, a hypothesis discharged at its #end) -> markup.italic: italics. A token style comes from a single winning theme rule, so each tier maps to one scope; scope stacks do not compose a colour from one rule with a font style from another. Clients without this mapping keep rendering plain function and parameter names.
