* feat(extraction): add Terraform and OpenTofu language support
Index .tf, .tfvars, and .tofu files via the tree-sitter-terraform dialect
of HCL (vendored from @tree-sitter-grammars/tree-sitter-hcl, Apache-2.0).
Symbols extracted:
- resource / data → class (qualified "type.name" / "data.type.name")
- module → module (qualified "module.name")
- variable → variable (qualified "var.name")
- output → variable (qualified "output.name")
- provider → namespace
- locals → constant per attribute (qualified "local.key")
References resolved cross-file:
- var.X, local.X, module.M[.out], data.T.N[.attr], <type>.<name>[.attr]
- built-ins skipped: each.*, count.*, self.*, path.*, terraform.workspace
The Terraform framework resolver disambiguates same-named candidates
across modules by preferring the one in the same directory as the
reference site, then by closest common-ancestor path, falling back to
the generic name matcher only when neither applies.
Validated on two Terraform monorepos (277 and 470 .tf files): indexing
runs in 1.3s and 2.4s respectively, query latency stays under 200ms,
and cross-module references resolve to the correct module 100% of the
time on inspected samples.
18 new extraction tests; full suite 1146/1148 green (2 pre-existing
flaky skips, 0 regressions).
* feat(terraform): bridge the module boundary and enforce directory scoping
Builds on #706. The module declaration was a dead end: module.M.out
resolved to the declaration and stopped, module inputs never reached the
child module's variables, and impact could not cross the boundary — on
real multi-module repos that breaks the core blast-radius question
("what breaks upstream if I change this module's variable/output").
- module blocks now wire across the boundary through :-scoped refs only
the Terraform resolver understands: module.M:var.<input> → the child's
variable node, module.M:output.<o> → the child's output node (emitted
alongside the module.M declaration ref), and module.M:file → the local
source directory's entry file (imports). Registry/git sources emit no
file ref and resolve nothing — an out-of-repo module stays a visible
boundary instead of a guess.
- .tfvars top-level assignments reference the variable they set, walking
up to the nearest ancestor directory (envs/prod.tfvars → root vars).
- Resolution now enforces Terraform's real scoping: same-directory only
(no cross-module fallback by common path prefix, no single-candidate
anywhere-in-tree binding), and terraform refs never fall through to
the generic name matcher — var.X can never legally bind outside its
module directory, so the fallback could only add wrong edges.
