What does automation look like, from the perspective of an automation tool developer, or a workflow designer.

  • Clarity between concept and code.
  • Easy to write.
  • Fast feedback when developing automation.
  • Provide good UX without needing to write UI code.

Command Context

At the bottom of every page, we will be building up a cmd_context, which holds the information about a workflow. Different commands can be invoked with the cmd_context to gather information about the workflow.

let mut cmd_context = CmdContext::builder()
    /* ?? */
    .build();

StatusCmd(&mut cmd_context).await?;
DeployCmd(&mut cmd_context).await?;
