There was a problem hiding this comment.
The original condition seems wrong. --add wasn't mentioned anywhere else in the repo and from how I understand the test, || makes sense here, not &&.

Fixes: #2188
Note: This PR fixes the same bug in two different code paths (
c.Find()andc.Traverse()). They use different helper functions for parsing the arguments, but the fix is based on the same idea.cobra/command.go
Lines 1090 to 1094 in 78bfc83
The idea is that whenever we encounter a shorthand combination, we search for the first flag in the combination that needs a value (if there are no such flags, then we just go to the next argument). If this flag is the last flag in the shorthand combination, then the value will be expected in the next argument. Otherwise, if the flag is not on the last position of the shorthand combination, the value is expected to be given in the same argument (in this case, we go to the next argument without doing anything).
