Class: RQ::Submitter

Inherits:
MainHelper show all
Defined in:
lib/rq-3.0.0/submitter.rb

Overview

the Submitter class is responsible for submitting commands to the queue, the commands it submits are taken from the command line, stdin, or the specified infile. the format of commands read from stdin or file is either a simple list of commands, one per line, where blank lines are ignored OR it is valid yaml input. if the Submitter sees the token ‘—’ in the input stream it is assumed the input is yaml. for an example of valid yaml input examine the output of a Lister using

rq q list

the output of other commands, such as that of a Querier may also be used as input to submit
