Summary

This project is a base class for running various commands in python from the command line.

see sample/toolbox_app.py for an example use.

see doc/api.md for the API available.

how to run

Don't specify a command gives you help. Note that you can use check() in toolbox_runner.py or run() in toolbox_app.py to specify a default command.

./doit 
WARN no command chosen, nothing to do
     py-runner-base: v0.1.0
     Choose one of these:
        task1               : run task1
        task2a              : run task2 step-a
        task2b              : run task2 step-b
        task3               : run task3
        task4               : run task4

Note: that there are several sorting orders available, see property sort_order in base_runner.py or cmd_map.py.

• Add an argument arg1:

$ ./doit task1 arg1
==== doit: starting...
     running Task1 args:['arg1']
     doit: run_it rc=0

• Run a command "task1" that has no prerequisites:

./doit task1
==== doit: starting...
     running Task1 args:[]
     doit: run_it rc=0

• Run a command "task2b" that has a prerequisite:

./doit task2b
==== doit: starting...
     running Task2 step-a
     running Task2 step-b
     doit: run_it rc=0

how to add commands

See the sample/taskxx.py files for example tasks. Note register() functions that allow you to specify command names for any tasks you want to add.

    # --------------------
    def register(self, runner):
        self._runner = runner
        self._runner.add_cmd('task2a', self._run_step_a, 'run task2 step-a')
        self._runner.add_cmd('task2b', self._run_step_b, 'run task2 step-b', prereqs=['task2a'])
