Universal Configuration Grammar.
This is an experiment in configuration management. The approach is not to create a "parsable" config file format. We have plenty of those. Instead we try to specify a grammar for describing configuration values that can then target various configuration formats to output to.
In theory this could support anything from command line flags to json to yaml or toml or even xml.
The goal is to allow a global shared configuration repository that can be version controlled, enforce some typesafety, and output configuration for any application regardless of that applications preferred format.
The Usual Warnings
This is still very much an experiment and the language and api can be expected to change and mutate. It also probably has bugs and isn't yet the most user friendly language and compiler to use. You have been warned.
Usage
You can get ucg with cargo cargo install ucg
.
Running ucg help will show the following output.
