But doing this in C already exists and works well. I don't understand the point of it. Although, in this day and age, rather than use the standard Unix toolset, people invent their own tools as if they are new. "Make" versus "npm" for example.

[slimsag]

Do you really think Make could replace npm?

[gopowerranger]

Make existed long before npm and make is the basis of all our package management in our company and our operating systems.

Recursive descent parsing can handle different class of languages from what yacc or bison can do. It is possible to build lexerless parsers this way (so scrap your old useless flex).

[gopowerranger]

So your trying to say this thing does a better job?

[gh02t]

I seriously doubt it ever will, but you have to start somewhere.

I've used Parsec before and it is certainly nice. Honestly I think it's a bit weird to try and shoehorn it into C, but hey maybe something interesting will come out of it.

What bugs me is the suggestion that just because bison works well enough, nobody should try and make a new parser generator in C. They will probably not take over the wold, bison is big and battle tested after all, but bison is itself also a replacement for older tools. And hey, maybe mpc here will succeed and revolutionize parsing for the best; then we can have this discussion again in 20 years about someone attempting to replace it.

[gopowerranger]

What you just said is this new thing isn't as good, and probably never will be, but you imply we should use it, even though the current tools are better.

See my complaint? If they are going to introduce a new tool, it must be better than the current tool. It's not and it's worse and not as mature.

[gh02t]

I didn't say you should use it, nor would I. Only that it isn't pointless/futile to attempt. No tool will be as mature as bison or what have you until it has also been battle tested for 25+ years, but 25 years ago bison was also new and upcoming.

Not to mention that this is not even really a parser generator like bison or yacc... it's a combinator library. It's an entirely different way to write a parser. It's like me saying Python shouldn't exist because I know how to write C.

[sklogic]

This one may not be that good. But any Packrat-based library is definitely much better than anything Yacc can offer.

[sklogic]

It is different, targetting a different set of use cases.
