Cotton is fill 4,\n wash 40 and drain 2, then 3 rinses (fill 3, rinse 6, drain 2), then\n spin 10, for 89 minutes. Quick takes 31 minutes, delicate 50, and spin\n only 10.\n- Events happen at the start of their minute, in the order typed: pause,\n resume, open, close, cut (the power) or on.\n- The door stays locked while the program runs and while there is water\n in the drum (from the first fill to the last drain). It also stays\n locked for a minute after the drum stops. The program cannot resume\n with the door open.\n- A power cut keeps the stage but loses the minutes done in it. When the\n power comes back, that stage starts again, or waits paused if the\n machine was paused or the door is open.\n- The finish is accounted for: the program's minutes, plus minutes\n paused, plus minutes without power, plus minutes done again after a\n power cut.\n\nWhat is checked: menu choices 1 to 4; a program name; 1 to 16 events,\neach a minute from 0 to 299 and an action, in order of minutes, or none.\nAn empty answer cancels. Events that make no sense at the time are\nrefused with the reason, such as resume when not paused or a second cut.\nThe run stops at minute 300.\n\nSessions: `sessions/basic.in` gives:\n- the four programs;\n- quick, straight through in 31 minutes;\n- quick with two pauses, the door refused and then opened, a resume\n refused with the door open, and a power cut in a drain, finishing at\n 42 = 31 + 7 + 3 + 1;\n- cotton with a 30-minute power cut 26 minutes into the wash: 145 = 89 +\n 30 + 26;\n- spin only.\n\n`sessions/bad-input.in` gives:\n- menu choices 0 and x; the program lizard; a cancel;\n- events abc, an unknown action, minutes out of order, an odd count,\n minute 300, and 17 events; a cancel;\n- events at the wrong time, each refused with its reason, around a pause\n and a power cut in the fill;\n- a pause never resumed: not finished by minute 300.\n\nBuilt on the verified corpus case `washing-machine-cycle-simulator`\n(stages with fixed times, run in order with a running total).\n", "modules": [ { "name": "main.eml", "eml": "# P098 washing machine: programs of timed stages, run minute by minute,\n# with pause and resume, a door that stays locked while it is unsafe, and\n# power cuts.\nimport washer\n\ndef plain(s):\n 0 => i\n len(s) => j\n while i < j and s[i] == \" \":\n i + 1 => i\n while j > i and s[j - 1] == \" \":\n j - 1 => j\n return s[i:j]\n\ndef pad(s, n):\n while len(s) < n:\n s + \" \" => s\n return s\n\ndef lpad(s, n):\n while len(s) < n:\n \" \" + s => s\n return s\n\ndef describe(name):\n washer.program(name) => p\n washer.stages(p) => st\n \"\" => line\n if p[0] > 0:\n \"fill \" + str(p[0]) + \", wash \" + str(p[1]) + \", drain \" + str(p[2]) + \", \" => line\n if p[3] == 1:\n line + \"1 rinse (fill \" + str(p[4]) + \", rinse \" + str(p[5]) + \", drain \" + str(p[6]) + \"), \" => line\n elif p[3] > 1:\n line + str(p[3]) + \" rinses (fill \" + str(p[4]) + \", rinse \" + str(p[5]) + \", drain \" + str(p[6]) + \" each), \" => line\n line + \"spin \" + str(p[7]) => line\n (\" \" + pad(name, 10) + lpad(str(washer.total(st)), 3) + \" minutes: \" + line) ^0\n\ndef show_programs():\n \"Programs, in minutes:\" ^0\n for name in [\"cotton\", \"quick\", \"delicate\", \"spin\"]:\n describe(name)\n \"The door stays locked while the program runs, while there is water in the drum, and for a minute after the drum stops.\" ^0\n\ndef show_events(events):\n if len(events) == 0:\n \"No events: the program runs straight through.\" ^0\n return\n \"\" => line\n for ev in events:\n if line != \"\":\n line + \", \" => line\n line + str(ev[0]) + \" \" + ev[1] => line\n (\"Events (minute and action): \" + line + \".\") ^0\n\ndef run(events):\n plain(input(\"program (cotton, quick, delicate or spin)> \")) => name\n if name == \"\":\n \"Cancelled.\" ^0\n return\n washer.program(name) => p\n if len(p) == 0:\n \"Type cotton, quick, delicate or spin.\" ^0\n return\n washer.stages(p) => st\n washer.total(st) => need\n washer.simulate(st, events, 300) => r\n (\"The \" + name + \" program, \" + washer.minutes(need) + \".\") ^0\n show_events(events)\n (\" \" + pad(\"minutes\", 10) + pad(\"stage\", 28) + pad(\"water\", 7) + \"door\") ^0\n 0 => first\n r[0] => tl\n for t in [1:len(tl)]:\n if t == len(tl) or tl[t][0] != tl[first][0] or tl[t][1] != tl[first][1] or tl[t][2] != tl[first][2]:\n \" \" => span\n if t - 1 > first:\n \"-\" + pad(str(t - 1), 4) => span\n \"no\" => water\n if tl[first][1]:\n \"yes\" => water\n (\" \" + lpad(str(first), 3) + span + \" \" + pad(tl[first][0], 28) + pad(water, 7) + tl[first][2]) ^0\n t => first\n for n in r[1]:\n (\"Minute \" + str(n[0]) + \", \" + n[1] + \": \" + n[2] + \".\") ^0\n if r[2] == -1:\n (\"Not finished by minute 300.\") ^0\n return\n \"\" => extra\n if r[3] > 0:\n extra + \" + \" + str(r[3]) + \" paused\" => extra\n if r[4] > 0:\n extra + \" + \" + str(r[4]) + \" without power\" => extra\n if r[5] > 0:\n extra + \" + \" + str(r[5]) + \" done again after a power cut\" => extra\n if extra == \"\":\n (\"Finished at minute \" + str(r[2]) + \", the program's \" + str(need) + \".\") ^0\n else:\n (\"Finished at minute \" + str(r[2]) + \" = the program's \" + str(need) + extra + \".\") ^0\n\ndef set_events(events):\n \"Events as minute and action, in order: pause, resume, open, close, cut (the power) or on.
