Subject: bug#77731: [PATCH] Add yank-media-handler for copied files from file manager
Date: Fri, 11 Apr 2025 14:58:32 +0530

[Message part 1 (text/plain, inline)]

[ This has been sitting in my drafts folder for many months now.  ]

Attached patch adds a yank-media-handler to message-mode to attach files
copied/cut from a file manager.  I tested this patch using pcmanfm and
xfe.  The regexp for the media-type was chosen after the blogpost [1],
pcmanfm in particular sets the media-type to
x-special/gnome-copied-files.

I strip the null byte in the split-string call in the handler because
pcmanfm adds a null byte at the end of clipboard selection.  I don't
know if this is the case with other file managers.

I also cannot find the spec of this clipboard type but [2] and pcmanfm
suggests that the selection is

    OPERATION
    file://FILE1
    file://FILE2...

where OPERATION is either cut or copy, and the rest of the lines are
links to the files.  I do the same as what Org does to parse the above.
