Nueyaml: YAML without the problems

Nueyaml is YAML stripped down to its essence so you can write complex configurations without the usual YAML pitfalls.

The problem with standard YAML

The original YAML specification buried a beautiful idea under 80 pages of features that cause more problems than they solve. It guesses what you mean, often guessing wrong:

# YAML surprises
country: NO      # may become false (Norway problem)
time: 12:30      # may become 750 (minutes)
version: 1.10    # may become 1.1 (float)
port: 08080      # may become 4176 (octal)

These "conveniences" turn configuration files into minefields. You quote some values defensively, but not others. You remember some gotchas, but not all. Your configuration works until it doesn't.

How Nueyaml fixes it

Nueyaml has one rule: be predictable. If it looks like a string to a human, it's a string:

# Nueyaml: No surprises
country: NO       # string "NO"
time: 12:30       # string "12:30"
version: 1.10     # number 1.10
port: 08080       # string "08080"

Only obvious numbers (123, 45.67) become numbers. Only true and false become booleans. Everything else stays a string.
