tree-sitter-hcl

tree-sitter grammar for the HCL language

Example

Highlighting example/example.hcl:

Developing

It is recommended to use nix to fulfill all development dependencies. To activate the development environment simply run nix-shell in the project root.

Running Tests

To run tests simply run nix-shell --run 'tree-sitter test'.

Compliance

The directory example/real_world_stuff contains a corpus of hcl files that I found with the github query language:HCL for users coreos, hashicorp, oracle and terraform-community-modules.

tree-sitter parse --quiet --stat example/real_world_stuff/*/*
