meme.alpha.platform.registry — io.github.beme-lang/meme-clj 0.10.0

Guest language registry. Maps language names to configurations. A guest language is: a name, a file extension, an optional prelude, and optional rewrite rules.

(register! :pattern {:extension ".pat" :prelude-file "langs/pattern/core.meme" :rules-file "langs/pattern/rules.meme"})

(resolve-lang "app.pat") → :pattern (lang-config :pattern) → {:extension ... :prelude ... :rules ...}

clear! clj/s

(clear!)

Clear all registered languages. For testing.

lang-config clj/s

(lang-config lang-name)

Get the config for a registered language. Returns nil if not found.

register! clj/s

(register! lang-name config)

Register a guest language. config keys: :extension — file extension (e.g. ".pat") :prelude-file — path to prelude .meme file (eval'd before user code) :rules-file — path to rules .meme file (eval'd, must return rule vector) :prelude — prelude forms (alternative to :prelude-file) :rules — rule vector (alternative to :rules-file) :parser — custom parser fn: (fn [tokens opts source] forms-vector) If nil, uses the default meme parser. The parser receives meme's token vector and should return a vector of Clojure forms.

registered-langs clj/s

(registered-langs)

List all registered language names.

resolve-lang clj/s

(resolve-lang path)

Given a file path, determine the guest language from its extension. Returns the language name keyword, or nil for unrecognized extensions. .meme files return nil (default meme, no guest language).
