Use TOML files as Racket configuration modules with compile-time schema validation.
Install with raco pkg install toml-config (or toml-config-lib to omit docs).
Documentation is at: https://joeldueck.com/what-about/toml-config
This package lets you turn TOML files into Racket modules by adding #lang toml/config at the top. The TOML data is parsed and provided as a hash table
that other modules can require and use.
More importantly, it provides a framework for creating custom configuration
languages with validated schemas. You can define domain-specific #lang
dialects that enforce required keys, type constraints, and default
values—catching configuration errors at compile time rather than runtime.
Parsing is all handled by the toml
package written by Greg
Hendershott, Winston Weinert, and Benjamin Yeung.
Application configuration: Racket programs can use TOML config files with validated settings, ensuring configuration mistakes are caught before the program runs.
Embedded DSLs: Library authors can create specialized configuration languages that use TOML syntax but add their own validation rules, types, and constraints specific to their domain.
