Job definitions in YAML

Three comments about this format:

First, schedule: weekday: {day: '*'} is pretty verbose. schedule: weekday: '*' seems cleaner. Similar for month.

Additionally, users can specify either day-of-week OR day-of-month (crontab), so a day-of-month indicator is needed.

possibly: "weekday" and "day" (for day-of-month)

schedule: 
  time: ...
  month: ...
  weekday: '1-5'

and

schedule: 
  time: ...
  month: ...
  day: '1,23'

Second point: Workflows have additional properties (keepgoing, strategy), so a simple sequence: [list] isn't enough.

We could do:

sequence:
  keepgoing: true
  strategy: node-first
  commands: 
  - exec: ...
  - script: ...

or change the key names a bit, replace sequence with workflow, and commands with sequence:

workflow:
  keepgoing: true
  strategy: node-first
  sequence: 
  - exec: ...
  - script: ...

Third item: All the workflow items allow some kind of argument string, but they are named inconsistently. "scriptargs" for the exec/script items, and then arg: line: for the jobref.

Suggest we change them all to be just "args" or "arguments" or something.

FYI: here is a first-pass at the yaml output for a job: https://gist.github.com/790772

Yes for second and third item.

For first item: can you just use crontab: "* * * * *" so I can cut and paste my crontab time info into a job definition?

Notes on format:

for schedule:

schedule: 
  time: ...
  month: ...
  weekday: 
    day: '1-4'

or

schedule: 
  time: ...
  month: ...
  dayofmonth: 
    day: '1-5'

crontab is supported:

schedule: 
  crontab: * * * * * *

For workflows the format is:

sequence:
  keepgoing: true
  strategy: node-first
  commands: 
  - exec: ...
    args: ...
  - script: ...
    args: ...
  - scriptfile: ...
    args:
  - jobref:
      name: jobname
      group: group
      args: args

For node dispatch parameters:

   nodefilters:
     dispatch:
       threadcount: 1
       keepgoing: true
       excludePrecedence: true
     include:
       tags: ...
     exclude:
       tags: ...
