Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Enrico Scholz (ensc) Assigned to: Nobody/Anonymous (nobody) Summary: [program_options] Endless loop with long default arguments Initial Comment: when using a po::value with a representation of the default value having a certain length, 'std::cout << opts' will stuck in an endless loop. E.g. ----- #include <boost/program_options.hpp> #include <string> #include <iostream> namespace po = boost::program_options; int main(int argc, char *argv[]) { po::options_description opts; opts.add_options() ("cfgfile,c", po::value<std::string>()->default_value("/usr/local/etc/myprogramXXXXXXXXX/configuration.conf"), "the configfile"); std::cout << opts; } ----- | $ rpm -q boost | boost-1.33.1-5 | | $ g++ foo.c -lboost_program_options | $ strace ./a.out | ... | write(1, " -c [ --cfgfile ] arg (=/usr/lo"..., 80 -c [ --cfgfile ] arg (=/usr/local/etc/myprogramXXXXXXXXX/configuration.conf) | ) = 80 | write(1, " "..., 80 | ) = 80 | write(1, " "..., 80 | ) = 80 | ... Removing one 'X' will result in an ugly | -c [ --cfgfile ] arg (=/usr/local/etc/myprogramXXXXXXXX/configuration.conf) t | h | e | c | o | n | f | i | g | f | i | l | e output. It would be nice, when: - the default value could be moved into the description column - the description would begin on a new line and an earlier column (e.g. 30-40) when option name/default-value are too long (> 30-40 chars) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=1528399&group_id=7586 ------------------------------------------------------------------------- Take Surveys.
