How to use

To use comb, you should create a python module file. we named slot.

A legal slot must be named ‘Slot’ in your module file and it must be at least contain four method:

  • initialize

    initial resource, e.g: database handle

  • __enter__

    get next data to do,you can fetch one or more data.

  • slot

    user custom code

  • __exit__

    when slot finished, call this method

Slot Demo


Execute a comb is very simple. just execute:

comb --root SLOT_ROOT_PATH  slot-package.slot-module

if you set SLOTPATH environment, you can use:

comb slot-package.slot-module

Quick View. call:

comb   comb.demo.list
