Some data formats are easy for humans to read but difficult for computers to efficiently parse. Others, like packed binary data, are dead simple for computers to parse but borderline impossible for a human to read.
XML bucks this trend and bravely proves that data formats do not have to be one or the other by somehow managing to be bad at both.
I wrote a powershell script to parse some json config to drive it’s automation. I was delighted to discover the built-in powershell ConvertFrom-Json command accepts json with // comments as .jsonc files. So my config files get to be commented.
I hope the programmer(s) who thought to include that find cash laying in the streets everyday and that they never lose socks in the dryer.
IIRC, the original reason was to avoid people making custom parsing directives using comments. Then people did shit like "foo": "[!-- number=5 --]" instead.
Alright, the YAML spec is a dang mess, that I’ll grant you, but it seems pretty easy for my human eyes to read and write. As for JSON – seriously? That’s probably the easiest to parse human-readable structured data format there is!
My biggest gripe is that human eyes cannot in fact see invisible coding characters such as tabs and spaces. I cannot abide by python for the same reason.
it is anything but easy to read if your entire file does not fit on a single screen.
I don’t know much apart from the basics of YAML, what makes it complicated for computers to parse?
The thing is, it was never really intended as a storage format for plain data. It’s a markup language, so you’re supposed to use it for describing complex documents, like it’s used in HTML for example. It was just readily available as a library in many programming languages when not much else was, so it got abused for data storage a lot.
