Usage

Convert TOML on stdin to JSON, filtering it through jq:

$ toml2json <<< 'wow = "amazing"' | jq

Produces:

{
  "wow": "amazing"
}

Convert TOML from a file and pretty-print it without jq:

$ toml2json --pretty ~/.config/kbs2/kbs2.conf

Produces:

Amazing. What more could you want? Hopefully nothing, because it will never do anything else.
