Parser Generator for C++

[pmatos]

Hi all,

I need to create a parser in C++ which should parse a somewhat complex
file structure. Yeah, it would be possible to write it from scratch in
C++ however I think it would be easier and the end-result would
probably be more efficient if I use a parser generator. However, I only
know flex/bison from a project in C along time ago. Any ideas on what
to use nowadays and for C++ would be nice.

Cheers,

AFAIK people who care and who can define the grammar of their files still
use lex/yacc (or their equivalents) to do the job.

How about boost.spirit at http://www.boost.org/libs/spirit/index.html

We had to use a flex/bison parser for a C++ project and had a hard time
calming the compiler to compile the generated code at all (g++)...
I think his question was reasonable and I'd be interested, too, if there
is such a thing for C++.

I´d refer to COCO (www.ssw.uni-linz.ac.at/Research/Projects/Coco/) which
will create code for C, C++, Pascal, C#, Java, etc....

did you look at bison++ ?

No joke?
Haven't heard of it yet, but sounds quite like what I'm looking for, thanks!

Hi, seems
http://www.mactech.com/articles/mactech/Vol.16/16.07/UsingFlexandBison/
used flex and bison with C++, never tried but if you say it isn't worth
it because resulting code is not g++ complaint, then I'll not even try.

Thanks for the remark,

Have you tried it yet? Is it nice?

Well, at least I have to disable all warnings and the -pedantic flag, as
well as declaring some functions as extern "C" to make the compiler
happy. But it works, if you can live with that

But at least three suggestions have been posted by the fellow posters
which sound very appropriate for your purpose, so I guess you're better
off with those pure C++ solutions.

I've been using it for two years in commercial applications. Previous to
spirit I avoid parsing issues as much as possible. Now I look for
opportunites whenever I can!

I like ANTLR www.antlr.org

Hi,

Although there were many suggestions and thank you all for the
suggestions I sticked with Spirit, I can tell you that the parser is
almost done. The library is just great!
