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.

Given that some language features are still missing ( see TODO ) there are some expected parse errors:

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

example/real_world_stuff/oracle/oracle%opengrok%opengrok-indexer%src%test%resources%analysis%terraform%sample.tf                                                              	1 ms	(ERROR [205, 8] - [214, 1])

Total parses: 2015; successful parses: 2014; failed parses: 1; success percentage: 99.95%

The aim is to build unit testcases from selected failure classes and slowly get to 100%.
