Calling jacob from the the command line gives this:
/usr/bin/env 'node\r' : No such file or directory

This is because there's an extra \r in the file:
jacob/cmd/cmd.js

At first line, when it tries to use the shebang:
#! /usr/bin/env node

If anybody has this issue, you can fix it with vim:
:set ff=unix

I'm working on a single page web app where I would love to include Jacob as a client side service. The current code contains a lot of requires (node includes). I do not require filesystem - just generating compilers/interpreters from grammar strings on the fly. Is this technical possible or is this waste of time if I try to delete all node.js dependencies?

Hi,
I spoted a bug in the Lexer:

This example expose the issue:

If we have those tree rules:

<> abc {console.log(`abc = ${this.jjtext}`);}
<> a {console.log(`a = ${this.jjtext}`);}
<> b {console.log(`b = ${this.jjtext}`);}

And we set the input : "abcab"

We expect to get:

abc = abc
a = a
b = b

But we get:

abc = abc
a = ab

Jacob is, in my oppignion, the best parser generator avalible for the platform if this bug could be fixed it would be awesome.

Cheers

Hi, I just recently discovered Jacob and the world of lexers/parsers so I don't know many about them.

I have a parser that allows me to parse a function call that looks like that:

exec myfunc(myvar)
exec myfunc("mytext")

Expression = 'DEFINED' 'ID' 'LBRACE' ('ID'|'MESSAGE') 'RBRACE' function(defined, id, _){console.log(defined, id, [...arguments].slice(3, -1));}

however, this parser only allow me to have one argument. I tried using regex to allow more but got rejected by the compiler.
Is it possible? Is there another way I didn't think of?
