diff

Show what sesamy provision would change, without writing anything.

sesamy diff web [-c sesamy.yaml ...]
sesamy diff server [-c sesamy.yaml ...]

What it does

Runs the full reconciliation against your live GTM workspace and prints a per-entity report:

• Create — entity is missing in GTM.
• Update — entity exists but its definition has drifted.
• No change — local matches remote.
• Unmanaged — entity exists in GTM but isn't described in your config.

No API mutations are made. Read-only API calls still count against quota.

Flags

Flag	Default	Purpose
-c, --config	sesamy.yaml	Config file(s).
-v, --verbose	false	Debug logging.

CI integration

Run sesamy diff on every PR that touches sesamy.yaml. A non-empty diff before merge means the change is real and previewable; a non-empty diff on main between deploys means someone hand-edited GTM.

Exit codes

Code	Meaning
0	Diff produced (may be empty or non-empty — both are non-error).
non-zero	Could not produce a diff (config invalid, API error, etc.).

TIP

The command itself does not exit non-zero when changes are pending. If you want CI to fail on drift, pipe the output and grep for change markers, or wire up your own check.
