v0.3.4

This is a large release with several features and many improvements added including:

• Enhancement of the Kubernetes search for kube_capture and kube_get
• Script function run_local now always return a result, even on error, to avoid halting script execution.
• Introduction of the new script function log to print timed messages
• Script configuration function kube_config now supports cluster context name
• Introduction of script module load when executing script using the exec package

run_local update

Before this release, a call to run_local with an error would cause the entire script to stop and exit in an error. With this release, when a run_local encounters an error, the error string is returned to the script, allowing for further handling.

log function

This new script function prints a message, along with an optional prefix, as part of the script execution:

log(prefix="Info", msg="Hello World!")

kube_config cluster context

This long-awaited update makes it possible for scripts that use Kubernetes-releated functions (kube_capture, kube_get) to use specify the cluster's context name to use to connect to the server.

kube_config(path="/path/to/kubeconfig", cluster_context="my-cluster")

Preloading script modules

This new feature is for people using the Crashd-Diagnostics packages to run their own script. With this addition, a script can be launched by passing both the script and a set of other library scripts which are pre-loaded before the actual script.

func main() {
    lib := `
def multiply(x, y):
    return x*y
`
    src := `log(msg="{} * {} = {}".format(3,5, multiply(3,5)))`
    exec.ExecuteWithModules("test", strings.NewReader(src), StarlarkModule{Name:"multiply", Srouce:strings.NewReader(lib)})
}
