Boost C++ Libraries: Ticket #5656: Support options without '='

Options without = just look weird.

Also, please don't set milestones when filing issues.

I'm trying to parse an existing format, so I don't get to decide what's valid and what's not.

I second this request. I'm trying to replace a 3rd party parsing library using boost::program_options, but the original config has comments starting with ; rather than #.

for example: ; this is a comment

Because program_options hardcoded # as comment and won't allow any line without = except sections, I had to abort this plan.

It would be much better to ignore weird looking lines rather than stop the whole parsing.

I'll third this request. Options created using boost::program_options::bool_value should not require a trailing equals sign when using parse_config_file. If --flagname= is a parse error for such an option according to command_line_parser, then flagname= should not be required by parse_config_file.
