nearley-unparse doesn't work with Typescript

[joereynolds]

Pretty much what the title says.

I have a grammar with @preprocessor typescript and that is compiled with nearleyc statement.ne -o grammar.ts.

I then try and use nearley-unparse grammar.ts but I'm met with

function id(d: any[]): any { return d[0]; }
             ^

SyntaxError: Unexpected token ':'

My current workaround is to remove the .preprocessor, recompile it and then I can unparse it

You should be able to compile with the --nojs option to remove preprocessors automatically.
