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,

Paulo Matos

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++.

did you look at bison++ ?

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

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....

Hi, seems
http://www.mactech.com/articles/mact...gFlexandBison/
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,

Paulo Matos

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! :D
