TOML是一种简单且易于阅读的配置文件格式，由前GitHub CEO Tom Preston-Werner于2013年创建。它旨在提供一种无二义性的语法，能够轻松转换为哈希表，强调人类可读性，特别适合用于配置文件。本文对比了TOML与其他格式如JSON和YAML的区别。

配置文件的使用由来已久，从.ini、XML、JSON、YAML再到TOML，语言的表达能力越来越强，同时书写便捷性也在不断提升。 TOML是前GitHub CEO， Tom Preston-Werner，于2013年创建的语言，其目标是成为一个小规模的易于使用的语义化配置文件格式。TOML被设计为可以无二义性的转换为一个哈希表(Hash table)。

Comparison with Other Formats

In some ways TOML is very similar to JSON: simple, well-specified, and maps easily to ubiquitous data types. JSON is great for serializing data that will mostly be read and written by computer programs. Where TOML differs from JSON is its emphasis on being easy for humans to read and write. Comments are a good example: they serve no purpose when data is being sent from one program to another, but are very helpful in a configuration file that may be edited by hand.

The YAML format is oriented towards configuration files just like TOML. For many purposes, however, YAML is an overly complex solution. TOML aims for simplicity, a goal which is not apparent in the YAML specification: http://www.yaml.org/spec/1.2/spec.html

The INI format is also frequently used for configuration files. The format is not standardized, however, and usually does not handle more than one or two levels of nesting.
