Crate for formatting .toml files using the toml crate.

$ cat examples/test.toml

[foo]
    data1 = { x = 1,   y = 2 }
data2 = {         x = 1, y = 2 }

      [bar]
data1 = { x = 2,     y = 1 }
  data2 = { x = 2,      y = 1 }


$ cat examples/test.toml | cargo run

[foo.data1]
x = 1
y = 2

[foo.data2]
x = 1
y = 2
[bar.data1]
x = 2
y = 1

[bar.data2]
x = 2
y = 1

Vim

Vim users can configure Vim to use toml-fmt as an external formatter for .toml files. First you need to install:

cargo install toml-fmt

Then set formatprg inside Vim:

set formatprg=toml-fmt

Then you can define this command to format the current file.

command! FormatFile normal! ggVGgq

Limitations

Currently the formatting is kind of ugly and verbose as there are few formatting options available upstream. If you have a request for a fancy formatting options, please open an issue at toml.
