#8009 closed Patches (fixed)

Error message does not show correct option name, if it contains a hyphen

Reported by: Markus Roth <markus.roth@…> Owned by: Vladimir Prus
Milestone: To Be Determined Component: program_options
Version: Boost 1.54.0 Severity: Problem
Keywords: Cc:

Description

When using a long option with a hyphen in its name, the error string does not output the option name, but rather the substring from the rightmost hyphen position.

Example: option foo-bar with double. 

./myprogram --foo-bar nonumber

Since "nonumber" cannot be cast into double, it throws an exception. The error message is: 

"the argument ('nonumber') for option '--bar' is invalid"

Option name is wrongly quoted as "--bar". Expected is "--foo-bar".

Check the attached example for reproduction. See the attached patch fixing the bug. SVN rev 82783.
