scrot -sf stopped working

[umanwizard]

since 95bea6b , we can't use -s as a short option (e.g., instead of -sf, we now have to type -s -f, because otherwise f is interpreted as an argument to -s.).

This has broken some scripts of mine on upgrading to Ubuntu 22.04 pre-release.

I believe that it is against standard command-line flag conventions to have -s take an argument despite being a short option.

The --select option now expects an optional argument.

Using the short option (-s) with the optional argument is valid, according to here:
getopt(3) — Linux manual page
Two colons mean an option takes an optional arg; if there is text in the current argv-element (i.e., in the same word as the option name itself, for example, "-oarg"), then it is returned in optarg, otherwise optarg is set to zero.

Ex:
-o arg default argument
-o default argument
-oarg optional argument given

[umanwizard]

That is a fair point, but it's still the case that scripts that were previously broken (because e.g. they invoke scrot -sf) are now broken.

I don't like breaking behaviors just for the sake of it, but I don't think that's dogma either 🔥
The new features (hide/hold/blur) are tied to selection and the only way the user communicates with us is through arguments and the best place for this was for the --select option to determine the behavior.
Anyway, I see that you already solved the problem easily.
