Hi

With the current implementation, the user does not have to supply the full option names, e.g. "--he" is as good as "--help", unless there is an ambiguity. Is there any way to disable this, i.e. allow only full matches?

The parse_command_line function has a 'style' parameter, when you don't specify a value then 'default_style' is assumed. You'd need to explicitly pass 'default_style' with 'allow_guessing' masked out. The styles are defined in cmdline.hpp. HTH, Volodya
