Triggering mail collection

How to get sup to collect mail from remote servers. ~/.sup/hooks/before-poll.rb

  File: ~/.sup/hooks/before-poll.rb
  Executes immediately before a poll for new messages commences.
  No variables.

Run fetchmail before polling for new messages:

if (@last_fetchmail_time || Time.at(0)) < Time.now - 60
  say "Running fetchmail..."
  system "fetchmail > /dev/null 2>&1"
  say "Done running fetchmail."
end
@last_fetchmail_time = Time.now

A similar example for offlineimap:

def offlineimap(*folders)
  cmd = "offlineimap -q -u Noninteractive.Basic"
  cmd << " -f #{folders * ','}" unless folders.compact.empty?
  `#{cmd} 2>&1`
end

def folder_names(sources)
  sources.map { |s| s.uri.split('/').last }
end

def inbox_sources(sources = Index.usual_sources)
  sources.find_all { |s| !s.archived? }.sort_by {|s| s.id }
end

if (@last_fetch || Time.at(0)) < Time.now - 120
  say "Running offlineimap..."
  # only check non-auto-archived sources on the first run
  log offlineimap(@last_fetch ? nil : folder_names(inbox_sources))
  say "Finished offlineimap run."
end
@last_fetch = Time.now
