Error management 

exit = (code = 0, err) ->

exit without error

 
  process.exit code unless err

exit with error

 
  console.error chalk.red.bold "FAILED: #{err.message}"
  console.error err.description if err.description
  process.exit code

process.on 'SIGINT', -> exit 130, new Error "Got SIGINT signal"
process.on 'SIGTERM', -> exit 143, new Error "Got SIGTERM signal"
process.on 'SIGHUP', -> exit 129, new Error "Got SIGHUP signal"
process.on 'SIGQUIT', -> exit 131, new Error "Got SIGQUIT signal"
process.on 'SIGABRT', -> exit 134, new Error "Got SIGABRT signal"
process.on 'exit', ->
  console.log "Goodbye\n" unless quiet

Main routine 

unless quiet
  console.log logo
  console.log chalk.grey "Initializing..."

scripter.setup (err) ->
  exit 16, err if err

Start argument parsing

 
  yargs
  .usage "\nUsage: $0 <job> [options]"
  .env 'SCRIPTER' # use environment arguments prefixed with SCRIPTER_

examples

 
  .example '$0 --update', 'to initialize and update the scripts'
  .example '$0 <job>', 'to simply run the job script'

add the jobs

validation

 
  .strict()
  .fail (err) ->
    err = new Error "CLI #{err}"
    err.description = 'Specify --help for available options'
    exit 2, err

now parse the arguments

 
  args = yargs.argv

implement some global switches

 
  chalk.enabled = false if args.nocolors

  unless args._.length

generall command

 
    unless args.update
      exit 2, new Error "Nothing to do specify --help for available options"
    console.log "Updating scripts..."

update scripts

 
    require('./update') (err) ->
      exit 1, err if err
