YAML [04 May 2019|01:48pm]

Seen in a blog entry by Martin Tournoij (via):

I’ve been happily programming Python for over a decade, so I’m used to significant whitespace, but sometimes I’m still struggling with YAML. In Python the drawbacks and loss of clarity are contained by not having functions that are several pages long, but data or configuration files have no such natural limits to their length.

[...]

YAML may seem ‘simple’ and ‘obvious’ when glancing at a basic example, but turns out it’s not. The YAML spec is 23,449 words; for comparison, TOML is 3,339 words, JSON is 1,969 words, and XML is 20,603 words.

There's more where the above came from. In particular, the portability issues are rather surprising.

Unfortunately for me, OpenStack TripleO is based on YAML.
