v1.0.15 - 2026-08-03

Fixed

• Type package collection logic (core robustness fix):
  • collectUsedPkgsFromType: *types.Named branch incorrectly walked TypeParams() (declaration-level type params like T any, which have no real package path); now walks TypeArgs() (instantiation type args like *common.Config) while retaining TypeParams() walk for cross-package references inside constraints
  • Does NOT call walk(t.Underlying()) on *types.Named: self-referential types (e.g. type Node struct{ Next *Node }) cause infinite recursion / stack overflow; cross-package references in struct fields / method signatures are covered by collectTypeNameAndUsedPkgs AST traversal
  • Added *types.Signature branch: function/method signature types (e.g. a provider returning func(*common.Config) error, or an invoke parameter being a function type) were previously not recursed into, so cross-package references inside signature params/results were not collected; generated code emitted full-path func(*github.com/.../common.Config) error instead of an alias, breaking compilation. Now walks Recv/Params/Results/TypeParams constraints, relying on seen for deduplication
  • addPkgToUsed changed from "typePkg single-value top-level package" to directly reuse collectUsedPkgsFromType full tree walk; no longer misses cross-package references inside Map key/value, slice elements, or generic type arguments
  • allTypes loop in generateClosureDef changed similarly: closure params / free vars / return types no longer rely on typePkg for only the top-level package; instead all cross-package references are tree-collected and EnsureAlias-ed individually

Removed

• Standalone -debug-aliases diagnostic flag: Alias mapping diagnostics are now unified under the global -debug log (prints [alias] prefixed alias info automatically when -debug is on); no separate flag is provided anymore
• findExcludedPackagesInClosure helper function: The BFS transitive import closure naturally excludes "other main packages" and "other library packages containing dig.Build" (Go forbids importing main packages, and library packages are never imported twice); the extra exclusion logic was dead code, removed without affecting generated output
• Single dig.Module per function restriction: findSingleModuleCall → findAllModuleCalls; helper functions may now contain multiple dig.Module calls whose args are merged; Module calls inside control flow (if/switch/for/select) remain unsupported
• Removed gen_failures/multi_module and gen_failures/multi_module_call regression examples (no longer error cases)

Changed

• Third-party library comparison matrix expanded: README and system prompts now include a complete dig / Wire / Fx comparison across architecture, API design, error handling, runtime/operations, and project status dimensions, plus per-tool trade-off analysis
• example/setup cleanup: Removed the redundant digen build tag from full.go and deleted stub.go (a placeholder only used in non-digen builds)
