Iris

TypeScript & JavaScript

Iris scans .js, .jsx, .ts, and .tsx files. Unused import detection (named, default, and namespace bindings that are imported but never referenced) is TS/JS only - Go and Python handle unused imports at the compiler or runtime level. For TypeScript-specific quality metrics (any usage, @ts-ignore suppressions, non-null assertions, missing return types), see TypeScript Metrics.

Go Support

Full Go analysis with language-aware routing:

  • Functions — both top-level func Name( and methods func (r *T) Name( detected
  • Third-party imports — packages with a dot in the root path segment (e.g. golang.org/x/..., pkg.example.com/...)
  • Debug prints — fmt.Print*, log.Print*, log.Fatal*, log.Panic* flagged in Code Lens and Code Smells
  • No-exports warning — flags if no capitalised (exported) function names are found
  • Unused Go modules — workspace scan reads go.mod and flags declared modules never imported across .go files
  • vendor/ directory — skipped automatically during workspace/folder scans

Python Support

Full Python analysis with language-aware routing:

  • Functions — all def declarations detected (top-level and class methods), with line numbers
  • Third-party imports — import pkg and from pkg import ...; stdlib modules are excluded automatically
  • print() calls — flagged in Code Lens and Code Smells
  • No public functions warning — flags if all functions start with _ (private by convention)
  • Unused Python packages — workspace scan reads requirements.txt and pyproject.toml and flags declared packages never imported across .py files
  • __pycache__, .venv, venv — skipped automatically during scans
  • Parameter lists — self and cls are excluded from the parameter count
