Scala Grammar doesn't give correct tokens with ANTLR4

[shiva10162]

I am working on ANTLR tool to parse the Scala file. I used the following grammar for it 👍 []https://github.com/antlr/grammars-v4/tree/master/scala .But using this grammar it doesn't give me correct tokens. I addressed my problem here completely with source code and example : http://stackoverflow.com/questions/40482259/antlr-doesnt-give-correct-output-tokens-for-scala-grammar. Please have a look. Cheers !

yes sure . but I am working on Antlr tool to parse Scala language. I am not working on Scala language grammar.

It would seem it is this rule

opchar           ::= // printableChar not matched by (whiteSpace | upper | lower |
                     // letter | digit | paren | delim | opchar | Unicode_Sm | Unicode_So)

which is actually defined as

opchar ::= printableChar

and therefore matching square brackets as part of identifiers and so on...

Hi,

I came across the same problem. Is there gonna be a fix for this?

Thank you.

Could some one suggest how to fix this? I am new to Antlr too, but need the scalar parser to work.

Thanks.

Hi @KvanTTT ,
Are there any efforts / plans to fix this at the moment ? Or is it not on the priority list for now ?
Please update us so that we can look at other options / try to fix it

I have no plans to improve Scala grammar in the near future.
