Question: How to check if workflow is a rerun?

[Matthias Küch]

Can I check if a run was invoked by Alfred by using wf.Rerun()?

Alfred passes top-level variables back to your Script Filter on rerun, so you can set a variable, e.g. Workflow.Var("is_rerun", "true"), and check for its existence to tell whether your Script Filter is being rerun.

I'm trying to get and set it using this snippet, while setting seems to work I can't read the variable in the subsequent run. Do you have any clue?

// get
isRerun := vars.Vars()["is_rerun"]
// set
wf.Var("is_rerun", "true")

Alfred sets workflow variables as environment variables. You need to read them from the environment with os.Getenv() or Workflow.Config.GetBool() etc.

Workflow doesn't import any environment variables: Workflow.Vars() only contains variables you've added with Workflow.Var() during that run.

If you need to load a whole bunch of environment variables, you can use Workflow.Config.To().
