# ---- The modern console library ----
# Every routine in console.asm, called with the cases that are easy to get wrong: a zero,
# the largest thing that fits, and a leading zero that should not print. The reading half
# is given a line longer than its buffer, so truncation and the swallowing of the rest

consoleTest | testPrograms/consoleTest.asm | run | consoleTest.in | -
# The console's status and control ports. Input here is a file rather than a terminal, so
# key mode has no terminal to change and only the mode bit moves: that is deliberate, since
# a program has to behave the same either way and a test needing a terminal could not run.
# What it pins down is that READY is clear at the end of input while ENDED is set, so a
# loop reading while READY stops on its own instead of taking imaginary bytes forever.

# Picking a typed line apart, which is how the shell understands anything. Includes a

# ---- CosmOS ----
# The system and its shell, driven by a script of commands. This is the first thing that
# uses the machine as a machine rather than exercising one part of it: it boots, mounts a
# disk written by the host tool, reads lines, and walks a directory to answer 'dir'.
cosmos | CosmOS/Source/cosmos.asm | run | cosmos.in | - | disks/sbfs.img
# The same with nothing attached. A shell that only works with a disk in the drive is not
# finished, so the empty machine is a case in its own right rather than an accident.
cosmosNoDisk | CosmOS/Source/cosmos.asm | run | cosmosNoDisk.in | -
# Loading a program and running it, which is the whole machine at once: the filesystem
# finds it, the controller writes it into Program Memory, the vector table carries its
# requests back to the system, and MVDS takes the Stack back when it stops. Every way
# load can refuse is tried first, and run is asked for twice, so the Stack being reclaimed
# rather than merely abandoned is what makes the second one work.
cosmosRun | CosmOS/Source/cosmos.asm | run | cosmosRun.in | - | disks/cosmos.img
# The monitor. It reads Program Memory, which the instruction set cannot do at all, so it
# works only through the controller. The targets are chosen to be stable: a loaded
# program's code and data, and the bank table, rather than the system's own code, which
# would churn whenever any library changed.
#
# Dumping the bank table is worth having on its own. It is the machine describing itself,
# and it shows the disk buffer that sbfsMount registered as bank 3 at boot.
cosmosDump | CosmOS/Source/cosmos.asm | run | cosmosDump.in | - | disks/cosmos.img
# The original hello.asm, brought over as an application. It is not much of a program,
# but it is the one that talks to the hardware directly: it writes to port 0x00 instead
# of calling osPrintString, so it is the case where a program reaches past the system and
# the system has to get control back anyway. run is asked for twice for the same reason
# it is in cosmosRun, and here it also says the Stack comes back from a program that never
# entered a service handler at all.
cosmosHello | CosmOS/Source/cosmos.asm | run | cosmosHello.in | - | disks/cosmos.img
# Life, which is the one program that had no end state to reach. It stops when the board
# settles, and the glider does settle: it crosses the field, hits the dead border, and
# collapses into a block at generation 54. NO CYCLE LIMIT ON PURPOSE. Whether it stops on
# its own is the whole point of the port, and a limit would answer that question for it.
#
# NOTHING IS TYPED AFTER run, and that is load bearing rather than tidy. Life polls the
# console between generations, and a byte sitting in the pipe is a byte waiting on the
# console as far as the machine is concerned - exactly as typing ahead at a terminal
# would be. An "exit" on the next line stops it at generation 1 and gets eaten. The shell
# ends the run by reaching the end of input instead, the way cosmosNoDisk does.
cosmosLife | CosmOS/Source/cosmos.asm | run | cosmosLife.in | - | disks/cosmos.img
# The other half of that: a key IS waiting, so it stops at once instead of at generation
# 54. The two together are what say the poll is reading the console rather than always
# answering the same way.
