EDIT from 2019: Hi folks. I wrote this gist for myself and some friends, and it seems like it's gotten posted somewhere that's generated some (ahem, heated) discussion. ~The whitespace was correct when it was posted, and since then GitHub changed how it formats <pre> tags. Look at the raw text if you care about this. I'm sure someone could tell me how to fix it, but~ (thank you @anzdaddy for suggesting a formatting workaround) honestly this is a random throwaway gist from 2015, and someone more knowledgable about this comparison should just write a proper blog post about it. If you comment here I'll hopefully see it and stick a link to it up here. Cheers. @oconnor663

Here's the canonical TOML example from the TOML README, and a YAML version of the same. Which looks nicer?

title = "TOML Example"
 
[owner]
name = "Tom Preston-Werner"
dob = 1979-05-27T07:32:00-08:00
 
[database]
server = "192.168.1.1"
ports = [ 8001, 8001, 8002 ]
connection_max = 5000
enabled = true
 
[servers]
 
  [servers.alpha]
  ip = "10.0.0.1"
  dc = "eqdc10"
   
  [servers.beta]
  ip = "10.0.0.2"
  dc = "eqdc10"
   
[clients]
data = [ ["gamma", "delta"], [1, 2] ]
 
hosts = [
  "alpha",
  "omega"
]
