module BBS::Goodbye

The last screen of a call, the way our boards hang up: thanks for calling, a note, where to find more of us, and NO CARRIER. On a modern terminal it is one write (::modern); on a C64 a reversed bar, then the modem’s +++, ATH0 and NO CARRIER a moment apart (::petscii).

call do |_ctx, runner|
  BBS::Goodbye.modern(runner, title: 'Feedia', note: "The stories are their publishers'.")
  nil
end

Constants

PAUSES: The seconds ::petscii waits before +++, before ATH0 and before NO CARRIER.
URL: Where more of us are.

Public Class Methods

modern (out, title:, note: nil, url: URL, clear: true)

Source

# File lib/bbs/goodbye.rb, line 39
def self.modern(out, title:, note: nil, url: URL, clear: true)
  out.write(modern_text(title: title, note: note, url: url, clear: clear))
  nil
end

Writes ::modern_text to out, anything with a write method: a BBS::FlowRunner, a BBS::Session, an IO. The arguments are those of ::modern_text.

BBS::Goodbye.modern(runner, title: 'Commodex BBS',
                    note: 'Games from wikidata.org (CC0).')

Returns nil.

# File lib/bbs/goodbye.rb, line 24
def self.modern_text(title:, note: nil, url: URL, clear: true)
  more = [note, "More of us: #{url}"].compact.join(' ')
  a = Ansi
  "#{a::RESET}#{a::CLEAR if clear}#{a::CRLF}  #{a::WHITE}Thanks for calling #{title}.#{a::RESET}#{a::CRLF}  " \
    "#{a::DIM_GREY}#{more}#{a::RESET}#{a::CRLF * 2}  #{a::BRIGHT_RED}NO CARRIER#{a::RESET}#{a::CRLF * 2}"
end

The text of ::modern: the screen cleared (unless clear is false), “Thanks for calling title.” in white, then dim note (when given) and “More of us: url”, then NO CARRIER in red.

petscii (screen, title: nil, bar: nil, note: nil, url: URL, color: Petscii::Colors::CY, width: nil) { |screen| ... }

Source

# File lib/bbs/goodbye.rb, line 64
def self.petscii(screen, title: nil, bar: nil, note: nil, url: URL, color: Petscii::Colors::CY, width: nil)
  screen = Petscii::Screen.new(screen) unless screen.respond_to?(:say)
  width ||= screen.respond_to?(:cols) ? screen.cols - 1 : Petscii::COLS - 1
  screen.cls
  screen.puts
  screen.puts bar_line(bar || "thanks for calling #{title}", color, width)
  screen.puts
  block_given? ? yield(screen) : screen.say([note, "More of us: #{url}"].compact.join(' '), color: Petscii::Colors::GR)
  screen.puts
  hang_up(screen)
  nil
end

The goodbye of a C64 board on screen, a BBS::Petscii::Screen (or a board’s screen with cls, puts and say), or on a session, which gets a BBS::Petscii::Screen. It clears the screen and writes:

a reversed bar in color, width columns: “ bar”, by default “ thanks for calling title”
what the block writes on the screen it is given, or else note (when given) and “More of us: url” as a dim paragraph
after PAUSES: +++, ATH0 and NO CARRIER in red

width: the bar’s width; default the screen’s cols less one, or 39

BBS::Goodbye.petscii(screen, title: 'feedia', color: YE,
                     note: "The stories are their publishers'.")
BBS::Goodbye.petscii(screen, title: 'the ttg wiki') do |s|
  s.puts " #{GR}the wiki on the web:#{LG}"
end

Returns nil. Raises what the session raises when the caller has hung up (IOError, Errno::EPIPE …).
