Program Options: canonical option name incorrect when hyphenated

[Tad Ashlock <tad.ashlock@…>]

When using a long option name like "external-device", if there is a problem, the name of the option in the error message is printed as "--device" instead of "--external-device". This is due to the implementation in error_with_option_name::get_canonical_option_name() in the value_semantic.cpp file. It calls strip_prefixes() when assigning the value to original_token. But strip_prefixes() simply uses find_last_of("-/"), which finds the dash within the option name and incorrectly uses the following character as the start of the option name.

I don't know the proper fix to apply in order to not cause errors in other uses of these functions.

Looks like this may have been fixed by

​https://svn.boost.org/trac/boost/changeset/82805

and see ticket

​https://svn.boost.org/trac/boost/ticket/8009

(I was having the same error with 1.54 and came to look up if/when it was fixed, found this ticket in addition to the other one).

Maybe you could close it if it works for you now?

I agree that the problem has been fixed, but I am (apparently) not authorized to close the ticket.
