@defvr {Scheme Variable} tree-sitter-build-system
This variable is exported by @code{(guix build-system tree-sitter)}. It
implements procedures to compile grammars for the
@url{https://tree-sitter.github.io/tree-sitter/, Tree-sitter} parsing
library. It essentially runs @code{tree-sitter generate} to translate
@code{grammar.js} grammars to JSON and then to C. Which it then
compiles to native code.
Tree-sitter packages may support multiple grammars, so this build system
supports a @code{#:grammar-directories} keyword to specify a list of
locations where a @code{grammar.js} file may be found.
Grammars sometimes depend on each other, such as C++ depending on C and
TypeScript depending on JavaScript. You may use inputs to declare such
dependencies.
@end defvr
Lastly, for packages that do not need anything as sophisticated, a
``trivial'' build system is provided. It is trivial in the sense that
it provides basically no support: it does not pull any implicit inputs,

;; Commentary:
;;
;; Build procedures for tree-sitter grammar packages. This is the
;; builder-side code, which builds on top of the node build-system.
;;
;; Tree-sitter grammars are written in JavaScript and compiled to a native
;; shared object. The `tree-sitter generate' command invokes `node' in order
;; to evaluate the grammar.js into a grammar.json file, which is then
;; translated into C code. We then compile the C code ourselves. Packages
;; also sometimes add extra manually written C/C++ code.
;;
;; In order to support grammars depending on each other, such as C and C++,
;; JavaScript and TypeScript, this build-system installs the source of the
;; node module in a dedicated "js" output.
;;
