The previous output is largely unusable. The result in the CI test runs is a 6GB
file with every compiled keymap in it and while we can grep for ERROR, it's not
particularly useful.
Let's change this and print out YAML instead - that can be machine-processed.
This patch adds a new parent class that prints itself in YAML format,
the tool invocations are child classes of that class. The result looks like this:
Example output:
- rmlvo: ["evdev", "pc105", "us", "haw", "grp:rwin_switch"]
cmd: "xkbcli-compile-keymap --verbose --rules evdev --model pc105 --layout us --variant haw --options grp:rwin_switch"
status: 0
- rmlvo: ["evdev", "pc105", "us", "foo", ""]
cmd: "xkbcli-compile-keymap --verbose --rules evdev --model pc105 --layout us --variant foo"
status: 1
error: "failed to compile keymap"
Special status codes are: 99 for "unrecognized keysym" and 90 for "Cannot open
display" in the setxkbmap case.
