Apparently NixOS didn't have Python (sometimes!) so let's not assume. By reusing the JSON "parsing" code from cowsay, we can self-disable to handle this case. Reported-by: Shahana Farooqui <shahana.farooqui@gmail.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Changelog-Fixed: Plugins: `clnrest` now correctly self-disables if Python not present at all.
