boost library to normalize the path

Is there any boost library that will normalize the unix file path.

For example)

1) input ////root///dir1///////dir2/dir3 should be normalized to

/root/dir1/dir2/dir3

2) input root///////dir4 should be normalized to

root/dir4

I was just wondering if there is boost library then i don't want to write my own

'boost::filesystem' has 'normalize()'. But an input like '////root///dir1///////dir2/dir3' simply is erroneous, thus I am not sure if you will get the desired result. Anyway, try it out:

filesystem::path pathName( “////root///dir1///////dir2/dir3” );

pathName.normalize();

cout << path'Name.string() << endl();

Oops- forgot to link the docs: http://www.boost.org/doc/libs/1_31_0/libs/filesystem/doc/path.htm

Sure I will try and see.
Its not errornous, one can do ls on such a path on unix and it does work.
so i need to handle such case in my code

Great!! This works like a charm.

Do I have use try catch?

perlperl

i know some boost need to catch as it can throw exception

jkr

I could not see that anything there would cause an exception (except a completely buggy path, but just in case:

filesystem::path pathName( “////root///dir1///////dir2/dir3” );

try {

    pathName.normalize();

} catch(filesystem::filesystem_exception& e) {

    // handle here
}

cout << pathName.string() << endl();

I think so its

filesystem_error and not exception

catch(boost::filesystem::filesystem_error& e

Yes, sorry - typo :-/

I even linked the correct page and spelled it wrong *grr*
