On: TOML: Tom's Obvious Minimal Language

[chubot]

I kinda agree, but I also think then you want unquoted keys

   {name: "value"}

And then maybe 123_456 syntax

It's a slippery slope ... pretty soon it's hard to write a JSON parser, and there are more bugs

The trailing comma one is trivial, I'll grant that

[marcosdumay → chubot]

Trailing commas a very highly impactful to the users, and trivial to the language writers.

The 123_456 syntax comes close to that, but is much less impactful.

None of those will make the language hard to parse.

[Spivak → marcosdumay]

As much as I think it's annoying I think no trailing commas enforces good coding hygiene and basically forces you to use a real encoder rather than as hoc string manipulations.

[rand_flip_bit → Spivak]

This is such a bad take

[Spivak → rand_flip_bit]

Care to like, elaborate? Stopping people from doing brittle stuff like

    print("{")
    for elem in list:
        print('"key": "value",')
    print("}")

seems like immediate worth.

[alwaysbeconsing → Spivak]

That's not a very big hurdle to overcome, though:

    print("{")
    contents = ""
    for elem in list:
      contents += '"key":  "value",'
    print(contents[:-1])
    print("}")

[marcosdumay → Spivak]

You are talking about data transfer encoding. Configuration languages are a completely different beast.
