Managing Technology Scopes

Noir detects the technologies in your code on its own. Use these flags when you want to add, limit, or drop some of them.

Flags

• -t, --techs <TECHS>: Add these techs to the analyzer set, on top of the auto-detected ones (comma-separated, e.g. rails,django).
• --only-techs <TECHS>: Run only these tech detectors (comma-separated, e.g. rails,django).
• --exclude-techs <TECHS>: Drop these techs from the result after detection.
• noir list techs: List all technologies Noir supports.

All three flags can be repeated. Tech names accept short forms: rails matches ruby_rails, and kemal matches crystal_kemal.

--techs and --only-techs look alike but work differently. --only-techs limits which detectors run, so the scan is faster and only those techs can be found. --techs forces a tech's analyzer to run even if detection missed it. Use both for "only these techs, and run them even if they weren't detected".
