# Convert a movie file to gif and copy its contents to clipboard.

# Technically: creates a .gif file in a temp dir and copies the path to
# clipboard, but that should be transparent.

f="$(mktemp).gif"
# Don't delete the file when done: the path is copied to the clipboard, not the contents.

# Copy only the path, leave the file on disk. It's the only way I know of to
# copy a GIF to clipboard in macos.
osascript -e 'set the clipboard to (POSIX file "'"$f"'")'
