[bug] Cannot build a library in a directory containing two parsers.

[Freed-Wu]

https://github.com/MichaHoffmann/tree-sitter-hcl has two parsers: hcl and terraform.

Similar bug for https://github.com/postsolar/tree-sitter-purescript and https://github.com/tree-sitter/tree-sitter-haskell.

these are bugs in the parsers

Yes, grantjenks/py-tree-sitter-languages@e38ce31 disable some languages.

disabled_langs = [
    "vue",  # html, angular
    "angular",  # html
    "purescript",  # haskell, unison
    "unison",  # haskell
    "svelte",  # org
    "terraform",  # hcl
]

When two parsers define same definitions, the symbols should have a namespace-like prefix.

re: NixOS/nixpkgs#263630

milahu/nur-packages@48f3c13

this works with all grammars except svelte and vue
