I am a YAML hater. The biggest thing about YAML that keeps biting me recently is this:

script:
    - echo "a key: a value"

throws parse errors because of the colon, even though it is inside a quoted string.

But there are lots of reasons to hate YAML.

Honestly, an underrated one to me is I just hate significant whitespace. I don’t want to use any language that supports it.

I’m working on a fault-tolerant JSON5 parsing library in the service of a JSON5-to-JSON and JSON5-to-YAML transpiler.

My goal is to never write any more YAML ever again.
