CCL FAQ

Are there types?

Section titled “Are there types?”

No. Keys and values are strings. Your application converts them:

port = 5432
enabled = true

The values in this case are "5432" and "true".

Can I use dots in keys?

Section titled “Can I use dots in keys?”

Yes. database.host is a literal string key with dots:

database.host = localhost  # Key: "database.host"

For nested structure, use indentation instead.

How do I nest?

Use indentation:

database =
  host = localhost
  port = 5432
