pod-babashka-instaparse

A pod exposing Instaparse to babashka.

It's recommended to use this pod via the instaparse.bb library.

API

Only a subset of instaparse is exposed. If you are missing functionality, please create an issue.

pod.babashka.instaparse

• parser
• parse
• parses
• failure?

Differences with instaparse

• Parser only works on a string grammar input
• The result of parser must be used with parse or parses, it cannot be called as a function directly

Example

(require '[babashka.pods :as pods])

(pods/load-pod 'org.babashka/instaparse "0.0.3")

;; loading the pod creates the instaparse.core namespace

(require '[pod.babashka.instaparse :as insta])

(def as-and-bs
  (insta/parser
   "S = AB*
    AB = A B
    A = 'a'+
    B = 'b'+"))

(prn (insta/parse as-and-bs "aaaaabbbaaaabb"))

(def failure (insta/parse as-and-bs "xaaaaabbbaaaabb"))

(prn failure)

(prn :failure? (insta/failure? failure))

Build

Run script/compile. This requires GRAALVM_HOME to be set.

Test
