Splitting Grammar and Lexer file #125

I want to put the lexer part in its own file. As described in http://zaach.github.com/jison/docs/#specifying-a-language it should work if i specify the lexer file as the second parameter of the jison command.

I've tried it with my own lexer file and ClassyLang grammar, but it didn't worked.

I get the following error (c.jison == classy.jison and c.jisonlex == classy.jisonlex):

E:\xxx\xxx\xxx\Global>jison c.jison c.jisonlex --debug

I've used the classy files from https://github.com/zaach/jison/tree/master/examples and JISON v 0.3.12.

Is this a bug or are the classy grammar files out of date or is there another way to split the lexer part from the grammar?

Looks like I have the same issue.

Reopen if this is still a problem as of >= v0.4.5.
