What command(s) is the bug in?

forge script

Operating System

macOS (Apple Silicon)

Describe the bug

When running forge script with the --verify flag, logs are not displayed if the transaction is not broadcasted. However, if the transaction does get broadcasted, the logs show up correctly.

Reproduction Steps

• Run a forge script with --verify flag but without broadcast flags
• Logs are not displayed
• Run the same script without --verify
• Observe that logs are now displayed

This affects debugging and monitoring of script execution, as developers expect to see logs regardless of broadcast status when verification is enabled.

[grandizzy]

@0xDirmes wonder why you pass the --verify if nothing to broadcast as there's nothing to be verified, if you remove it then logs are displayed. Is there a scenario I am missing, please advise, thank you

[grandizzy]

--verify without --broadcast is a NOOP, we're going to allow verify only when broadcast / resume is passed

[0xDirmes]

Hey @grandizzy that makes sense, I have no usecase for running with the --verify flag on dry-runs but it just seems odd that passing that flag suppresses output. Allowing verify when broadcast is passed seems better developer experience

[IronJam11]

can i take up this issue

[onbjerg]

For future referenece, we are going to disallow --verify without --broadcast, see #11734. As such, solving this issue standalone is out of scope. I will keep it open until the mentioned PR is merged.
