Hi,
in Boost 1.37.0, this program
#include <iostream>
#include <string>
#include
int main(int argc, char * argv[])
{
using namespace std;
using namespace boost::program_options;
options_description cmdline_options("Supported options");
cmdline_options.add_options()
("help", "this is a sufficiently long text to require word-wrapping")
("prefix", value<string>()->default_value("/h/proj/tmp/dispatch"), "root path of the dispatch installation")
;
cerr << cmdline_options << endl;
return 0;
}
displays a usage message that looks weird:
$ g++ foo.cpp -lboost_program_options.a && ./a.out
| Supported options:
| --help this is a sufficiently long text to requ
| ire word-wrapping
| --prefix arg (=/h/proj/tmp/dispatch) root path of the dispatch installation
It appears that the word-wrapping algorithm can't handle the default
argument properly. Is that a known problem? Can I work around that
somehow?
I also wonder whether it's possible to format the help string such that
it's printed in the *next line*, like this:
| --prefix arg (=/ridiculously/long/path/that/leaves/no/room/on/right/side)
| root path of the dispatch installation
I tried adding a '\n' at the beginning of the help string, but that
didn't have the desired effect. Is there any way to accomplish this?
Take care,
Peter
