Doit task for updating completion on new version

[Balakrishnan B]

I want to create a task that updates the shell completion file. I have the below and it works.

def task_version():
    return {'actions': ["doit --version"]}


def task_update_completion():
    from doit.tools import result_dep
    zsh_completion_file = '~/.zsh/tabcompletion/_doit'
    return {
            'actions' : [f'doit tabcompletion --shell=zsh > {zsh_completion_file}'],
            'uptodate': [result_dep('version')],
            'verbosity' : 2
            }

Is there a way to avoid creating a 'version' task just for tracking its dependency? I don't want to see version in doit list or in autocompletion. Is there a way to hide the task? It would be good nice to pass arbitrary python function for result_dep. E.g

def task_update_completion():
    from doit.tools import result_dep
    zsh_completion_file = '~/.zsh/tabcompletion/_doit'
    def get_ver():
        return doit.get_version()
    return {
            'actions' : [f'doit tabcompletion --shell=zsh > {zsh_completion_file}'],
            'uptodate': [result_dep(get_ver)],
            'verbosity' : 2
            }

Please share if there is a better way to create a task for tab completion update.

Thanks,

Bala
