(toml) Add support for TOML arrays

[marcinx]

Hi Team,

TOML currently handles this case correctly

moo=["foo"]

but highlighting is not applied when multiple values are present in the array, e.g.

KNOWN_PEERS = [
    "finland.some-host.com:11625",
    "germany.some-host.com:11625",
    "hongkong.some-host.com:11625",
]

Thanks for your help!

The problem is we don't support arrays at all.. and we assume values must be on a single line... so we realize that you have a string (we know nothing about the array), but the rest is not because at the end of the line we have no idea what the rest of that content it.

If you moved it all to one line you'd see the strings all colorize I believe, of course we still wouldn't know anything about arrays. :)

Someone wanting to tackle this would need to add REAL array support to ini to detect array elements, etc... this would start to feel a lot like the JSON parser. Right now the "value" parsing part of ini is not that clever.

At that point it might make sense to split out ini from TOML though (not sure).

Could be beginner friendly. You'd learn a lot by looking at the JSON grammar as an example.
