command / cmd exec error handling

[sjwl]

How can I catch errors from exec.Run commands and gracefully handle it?

Given the example below, if I run cue demo . instead of printing out "failed", it prints task failed: command "ls does-not-exist" failed: exit status 1

package foo

import (
        "tool/cli"
        "tool/exec"
)

command: demo: {
        apply: exec.Run & {
                cmd: ["ls", "does-not-exist"]
                stdout: string
                stderr: string
        }

        result: [
                if apply.success {
                        "success"
                },
                if !apply.success {
                        "failed"
                },
        ]

        print: cli.Print & {
                text: result[0]
        }
}

Open issue and work around: #1499

thanks for the response. The workaround seems to be forking my own version of tool/exec pkg?
