NaplpsWriter

This project is an Elixir implementation of a library to create NAPLPS graphics files. NAPLPS is the graphics format used in the Prodigy Online system, revived at The Prodigy Reloaded project.

This code

  import NaplpsWriter
  use NaplpsConstants
  ...
      gcu_init()
      |> append_byte(@cmd_shift_in)
      |> select_color(@color_blue)
      |> draw(@cmd_set_point_abs, {75 / 256, 75 / 256})
      |> draw(@cmd_line_rel, [
        {25 / 256, 100 / 256},
        {50 / 256, -100 / 256},
        {-90 / 256, 55 / 256},
        {100 / 256, 0 / 256},
        {-85 / 256, -55 / 256}
      ])
      |> draw(@cmd_set_point_rel, [])

will produce a drawing
