Toml Maid - Keep your TOML files clean

toml-maid crate toml-maid documentation

This formatter tries to apply an opinionated consistent formatting style.

Mainly, it considers lines not separated by blank lines as blocks, such that sorting is only applied inside each blocks. It matches the practice in some big Rust repositories to separate dependencies in sections, when many other formatters don't take that into account and scramble the sections.

Installation

cargo install toml-maid

Usage

Run toml-maid <my_file.toml> to format a file. Many files can be provided. Use the --folder <path> option to register a folder that toml-maid will scan recursively for any TOML file (except toml-maid.toml files). Both can be used together. If neither are used then the current folder is registered (equivalent to toml-maid --folder .)

The --check option allows no modifying any file, and will instead exit with an error code if a file is not well formatted. The --silent options allows not outputing unimportant messages.

Configuration

Behavior of toml-maid can be configured using a toml-maid.toml file, which can be located in the current path or any parent folder, the first encountered being used and others ignored. The options are the following:

  • keys: list of keys as strings that should be sorted first in non-inline tables ([section] and key = { ... } entries). This can be used to keep important entries first.
  • inline_keys: same but for inline tables foo = { key1 = .., key2 = ..}.
  • sort-arrays: boolean telling if arrays should be sorted. Should only be used if order is not important, for exemple is suitable to keep Cargo.toml list of features ordered.
  • excludes: list of patterns to ignore when scanning directories

TODOs

  • Improve comments formatting in multi-line arrays, mainly always move comments after the comma.
  • Allow to configure ignored folder when scanning folders recursively (for exemple in this repo the tests/output_consistency folder should not be formatted as it contains by design non-formatted files).
  • Add cute anime girl to README
