This PR increases the TypeScript type-safety and can be seen as a follow-up of #90
TypirSpecificsnow contain the propertyLanguageKeys: Record<string, unknown>;to make language keys explicit. This is the precondition for the following improvements:Specifics['LanguageKeys']to simplify inference rules for functions and operators: Now it is possible to skip the TypeScript type when using onlylanguageKeyand nofilter. @Lotes You sketched this idea some time ago and now we have everything to make your idea happen 🙂Contributions of this PR which are not related to language keys:
languagePropertysupports only valid property names of the givenlanguageNodeOpen issues:
Specifics['LanguageKeys']now even in Typir (core), we could support the featuresaddValidationRulesForAstNodesandaddInferenceRulesForAstNodes(which are Typir-Langium only so far) also in Typir (core): I would prefer that (but did not implement that yet), what do you think?typir.ts, there are two open issues/improvements marked with// possible extension, for which I found no solution so farI recommend to review this PR commit by commit.
