Compiler for gbnf format?

[cdaman123]

Hello,

I am facing some conditions where llama output completes at : token. I added markdown in JSON grammar. I want to check state machine of my new grammar regex. Is there any compiler available for gbnf like bnf. Or what is different b/w the syntax of bnf and gbnf.

Please help me with resolving this issue.
Thank You.

Hey @cdaman123!

For validating the compiled grammar, the output of main when used with --grammar will contain a debug message with the compiled grammar representation that might be helpful:

main: grammar:
root ::= object 
object ::= [{] ws object_11 [}] 
value ::= object | array | string | number | boolean 
array ::= [[] ws array_15 []] 
...

This form of the grammar is pretty low level and pretty directly maps to the in-memory representation.

For something like a specification of the syntax, check out the GBNF guide at grammars/README.md if you haven't already.

Let me know if that helps or if you were after something else.
