kdl

Even if you don't use KDL, you might enjoy seeing its use of "slashdash comments" -- this is a great idea to steal if you ever write your own language! [1] package name my-pkg version "1.2.3" // ... rest of example at https://kdl.dev // "Slashdash" comments operate at the node level, // with just `/-`. /-this-is-commented { this entire node { is gone } } } KDL v2 spec : slashdash comments: https://github.com/kdl-org/kdl/blob/main/draft-marchan-kdl2.... [1] Other languages have it -- this first one that comes to mind is Clojure which allows commenting out of an expression with `#_` (a reader macro): https://clojure.org/reference/reader#_dispatch

IMO, there’s a wide unexplored design space between the minimalism of Lisp and richness of other languages. A programming language inspired by something like KDL (https://github.com/kdl-org/kdl) has the potential to be in a very sweet spot between the two. "Everything is a node" instead of "everything is a list" is only slightly more complicated, but also vastly more readable that a soup of parenthesis.

I think maybe I would prefer HCL. instead of: GET https://example.org/data.tar.gz HTTP/1.0 200 [Asserts] sha256 == hex,039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81; ...this? get "https://example.org/data.tar.gz" { sha = "039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81" } Or, having a separate category for asserts: get "https://example.org/data.tar.gz" { asserts { sha = "039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81" status = 200 } } Or KDL (https://github.com/kdl-org/kdl): get "https://example.org/data.tar.gz" { asserts { sha "039058c6f2c0cb492c533b0a4d14ef77cc0f78abccced5287d84a1a2011cfb81" status 200 } }

KDL is a variant of SDLang that’s worth checking out. https://github.com/kdl-org/kdl

I'd love to understand why all the advertised implementations have permissive licenses except for the Rust implementation, which is released under the Parity Public License 7.0.0 [1]? This seems to be as restrictive as the GPL, no? In my mind, copyleft licenses applied to infrastructural projects like kdl-rs prematurely limits their adoption and promotes the development of alternatives with more permissive licensing, since the spec is released under a Creative Commons license [2].
