Write pipeline

A pipeline in alfred is a command that invokes other commands. No fuss … The declaration remains identical to a command.

Write a command chain

alfred/ci.py

import alfred

@alfred.command('ci', help="execute continuous integration process")
def ci():
    alfred.invoke_command('lint')
    alfred.invoke_command('tests')

Warning

You can’t a subcommand directly using lint(). Currently the pattern is not supported and even if it may work in the future, it will broke as soon as you move the command lint into another module.

Use optional parameter in command chain

A pipeline can pass an optional parameter to the commands it invokes.

alfred/ci.py

import alfred

@alfred.command('ci', help="execute continuous integration process")
@alfred.option('verbose', help="run continuous integration in verbose mode", is_flag=True, default=False)
def ci(verbose):
    alfred.invoke_command('lint')
    alfred.invoke_command('test', verbose=verbose)
