Why CCL?

Section titled “Why CCL?”

Simple human-readable syntax

CCL is easy to read and write. The syntax is delightfully ", {, and } free! You can use indentation to organize hierarchical data, but you don’t have to.

Comments and multiline values

Unlike JSON, CCL supports comments and multiline values. Configuration files should be human-friendly.

Composable and extensible

The CCL core focuses on string-only key-value pairs with a progressive API. Build custom features on this simple foundation.

Mathematical foundation

Based on Category Theory principles, CCL provides predictable composition and merging behavior.
