tree-sitter-language-pack.cr

Crystal bindings for tree-sitter-language-pack (180+ tree-sitter grammars + code-intelligence), generated by alef. The native libts_pack_core_ffi is downloaded from the upstream GitHub release (Go-style download_ffi), since Crystal has no registry for prebuilt native shards.
