Invoke-SpectreScriptBlockQuietly

Synopsis

This is a test function for invoking a script block in a background job inside Invoke-SpectreCommandWithProgress to help with https://github.com/ShaunLawrie/PwshSpectreConsole/issues/7
Some commands cause output that interferes with the progress bar, this function is an attempt to suppress that output when all other attempts have failed.

---

Description

This function invokes a script block in a background job and returns the output. It also provides an option to suppress the output even more if there is garbage being printed to stderr if using Level = Quieter.

---

Examples

This example invokes the git command in a background job and suppresses the output completely even though it would have written to stderr and thrown an error.

Invoke-SpectreScriptBlockQuietly -Level Quieter -Command {
    git checkout nonexistentbranch
    if($LASTEXITCODE -ne 0) {
        throw "Failed to checkout nonexistentbranch"
    }
}
