[introduction to toml]

TOML is a language created in 2013 by the former GitHub CEO, Tom Preston-Werner, with the goal of becoming a small, easy-to-use semantic profile format. TOML is designed to be converted into a hash table (Hash table) without ambiguity.

The official Chinese introduction is here: https://github.com/toml-lang/toml/tree/master/versions/cn

The third-party parsing package used under walker is: https://pypi.org/project/toml/

[config.toml]

# input directory SrcRoot ='D:\ test\ input'# output directory DstRoot ='D:\ test\ output'
