internal/cmd/env_diff.go:87–102

ToShell applies the env diff as a set of commands that are understood by the target `shell`. The outputted string is then meant to be evaluated in the target shell.

(shell Shell)

// the target `shell`. The outputted string is then meant to be evaluated in
// the target shell.
func (diff *EnvDiff) ToShell(shell Shell) (string, error) {
	e := make(ShellExport)

	for key := range diff.Prev {
		_, ok := diff.Next[key]
		if !ok {
			e.Remove(key)
		}
	}

	for key, value := range diff.Next {
		e.Add(key, value)
	}

	return shell.Export(e)
}

// Patch applies the diff to the given env and returns a new env with the
// changes applied.
