Support for TOI Executors

This package provides a generic command line tool support to provide TOI executor CLIs.

Such a CLI wraps an executor specific executor function. If no options are passed it complies to the TOI image binding contract.

For development purposes it can be called with a bunch of option to fake the file system binding and redirect it to explicitly specified files.

It provides a contract to the executor function of type

func(options *ExecutorOptions) error

which already reolves all those dependencies by providing an ExecutorOptions object with the prepared contract data, including access to to the ocm.ComponentVersionAccess of the component version providing the package to work on.

A typical main function of an executor could then look like:

     package main

     import (
        "os"

        "github.com/open-component-model/ocm/v2/pkg/contexts/clictx"

        "yourpackage"
     )

     func main() {
        ctx:=clictx.New()
        // special configuration of the context. e.g. setting a virstual filesystem
        c := support.NewCLICommand(ctx.OCMContext(), "your executor name", yourpackage.ExecutorFunction)
        if err := c.Execute(); err != nil {
            os.Exit(1)
        }
     }
