+## Compliance

+The directory `example/real_world_stuff` contains a corpus of hcl files that I found with the github query `user:hashicorp language:HCL`. Just to be sure I encrypted them using `git-crypt`.

+Given that some language features are still missing ( see TODO ) there are some expected parse errors:
+
+```bash
+nix-shell --run 'tree-sitter parse --quiet --stat example/real_world_stuff/*'
+...
+...
+Total parses: 886; successful parses: 801; failed parses: 85; success percentage: 90.41%
+```

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