Hi,
I suggest to improve options' parsing error recognition, since
program_options does not throw an exception for command line options
that are substrings of actual options.
To be clear : assume we add an option "myoption" with the
boost::program_options::options_description::add_options() function.
The following command line options are recognized (program_options
does not throw an exception):
myoption [OK,should be recognized]
myopt [BAD,should not be recognized]
The following command line options are not recognized (program_options
throws an exception):
myoptions [OK,should not be recognized]
myopr [OK,should not be recognized]
I suggest program_options should parse the entire option string until
reaching a '=' or ' ' character, and then trying to recognize this
option.
Best,
Florent
