wl-copy --type option ignored for text

[vadz]

I'd like to put some text into clipboard in text/plain format only, i.e. without the TEXT, STRING and UTF8_STRING formats also used for it by default, but it seems that --type text/plain is ignored in this case and all the other types are still added:

$ wl-copy 'some text'
$ wl-paste -l        
text/plain
text/plain;charset=utf-8
TEXT
STRING
UTF8_STRING
$ wl-copy -t text/plain 'some other text'
$ wl-paste -l                      
text/plain
text/plain;charset=utf-8
TEXT
STRING
UTF8_STRING

This looks to be trivial to fix, as it would be enough to change the condition in this line

or just make it an else like this:

but I don't make a PR for this as I'm not sure if this is not intentional. If you'd like one, please let me know.

Hi, this was very intentional. As you note, --type is not ignored, but we additionally offer generic text formats if the type you specify with --type looks textual; without this, many clients will refuse to paste your data.

Why is this an issue for you / what are you actually trying to achieve?

I see, thanks. Maybe there could be some --force-type option to still do what I want? But it's probably too niche...

I'm testing one of such broken clients :-) and I need to be able to put text on clipboard without providing it as [UTF8_]STRING to trigger the bug. It can be done manually by copying text from Nautilus but wl-copy is just so much more convenient to use (thanks a lot for this great tool, BTW!). And I was also thinking of adding a non-interactive test checking that pasting text in any format works and for this I could only use wl-copy.
