What do you recommend? IMO percent-escaping is readable enough and increases
the size of the already long string not too much.
The encoding of the JSON
{"type":"deb","os":"ubuntu","name":"dpkg","version":"1.22.6ubuntu15","architecture":"amd64"}
would be:
-Wl,--encoded-package-metadata=%7B%22type%22:%22deb%22%2C%22os%22:%22ubuntu%22%2C%22name%22:%22dpkg%22%2C%22version%22:%221.22.6ubuntu15%22%2C%22architecture%22:%22amd64%22%7D
At first it might look confusing, but the relevant strings can be seen on a
second look: "type", "deb", "os", "ubuntu", "name", "dpkg", "version",
"1.22.6ubuntu15", "architecture", "amd64". Only the beginning of the version
number is harder to see.
There are multiple tools that can encode/decode it. For example Python's
urllib.parse.unquote and urllib.parse.quote.
I am open for better encodings. I am open for making --package-metadata
percent-decode the value instead of adding a new parameter. Percents are
relative safe encoding option. The Debian package name and the Debian version
are not allowed to contain percents. The os, type, and architecture will not
have percents in them.
