2019-02-01cam: options: Add option type handling to options parserLaurent Pinchart
Extend the options parser with support for option types. All options must now specify the type of their argument, and the parser automatically parses the argument and handles errors internally. Available types are none, integer or string. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Niklas Söderlund <niklas.soderlund@ragnatech.se>
2019-02-01cam: options: Return whether addOption() succeeds or notNiklas Söderlund
To later extend the options handling to cover subparsing of arguments it will be needed to know if the addition of the option itself was successful or not. The information is already present in addOption() this change just makes it available.

2019-02-01cam: options: Create a template class for optionsNiklas Söderlund
In preparation to adding more parsers create a template class to hold the parsed information. The rational for making it a template are that different parsers can index the options using different data types. The OptionsParser index its options using an int while the upcoming KeyValyeParser will index its options using strings for example.

2019-01-25cam: options: optional arguments needs to be specified as --foo=barNiklas Söderlund
It's not stated in the getopt_long documentation but optional arguments need to be specified as '--foo=bar' instead of '--foo bar', otherwise the value is not propagated to optarg during argument parsing. Update the usage printing helper to reflect this requirement. Signed-off-by: Niklas Söderlund <niklas.soderlund@ragnatech.se> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2019-01-22cam: options: Don't implement move semantics for OptionsParser::OptionsLaurent Pinchart
The compiler creates a move constructor automatically when none is supplied, and it does the right thing by default in this case. Using std::move() inside the function prevents the compiler from doing return value optimization and actually hinders performances. Using std::move() in the caller is unnecessary, the move constructor is used automatically by the compiler. For all these reasons remove the tentative optimization that resulted in worse performances and worse code.
