Python3.g4 grammar not working

[arman000]

The Python3.g4 grammar works fine with the standard ANTLR 4.5 "grun" macro. However, it doesn't work with clj-antlr in lein repl:

(require ['clj-antlr.core :as 'antlr])
(def python3 (antlr/parser "grammars-v4/python3/Python3.g4" {:root "file_input"}))
(python3 "2 + 2\n")

==> ParseError no viable alternative at input '+ '  clj-antlr.common/parse-error (common.clj:146)

Sorry if this is a noob issue. I'm very new to Clojure.

I wonder if it's cuz the version of Antlr we depend on is older. Can you add a failing test perhaps? Or try bumping the antlr version in project.clj?

[arman000]

I tried bumping the antlr and antlr4-runtime versions to 4.5 However, a couple of clj-antlr tests failed. So, I assume that some porting effort is required for 4.5. I also tried running the unmodified clj-antlr (v0.2.2) against an old version of Python3.g4. However, that didn't work either. If I get a little more proficient at Clojure, perhaps I'll look into fixing this problem.

Aw, I'm sorry bout that. I wish I had time to dig in there and fix this for you right now!
