This is a complete rewrite and restructure of the entire emulator
project, as part of the effort in locking down the Bedrock specification
and in creating much better tooling for creating and using Bedrock
programs.
This commit adds a command-line argument scheme, an embedded assembler,
a headless emulator for use in non-graphical environments, deferred
window creation for programs that do not access the screen device,
and new versions of phosphor and bedrock-core. The new version of
phosphor supports multi-window programs, which will make it possible to
implement program forking in the system device later on, and the new
version of bedrock-core implements the final core specification.
Fix mapping of draw operations in screen device2024-09-10T00:50:44ZBen Bridlebridle.benjamin@gmail.com2024-09-10T00:50:44Zurn:sha1:03c4b069e1806af256730639cefdae115b24401a
The mapping of draw codes to draw operations didn't match the screen
device specification. This error was introduced in commit 6b3796c.
Update version to 0.5.02024-09-07T07:25:42ZBen Bridlebridle.benjamin@gmail.com2024-09-07T06:33:08Zurn:sha1:473d1b07e024e48e32c0c475cbf4dfdc42a1b4b3Update bedrock_core dependency to v4.0.02024-09-07T06:32:37ZBen Bridlebridle.benjamin@gmail.com2024-09-07T06:32:37Zurn:sha1:aa6234821c99d6bfc1a77180643e6bb0c87fa2b8
This version of bedrock_core conforms to the final Bedrock core
specification, which will not be changed from this point forward.
Implement DB4 instruction for unit tests2024-09-07T06:29:52ZBen Bridlebridle.benjamin@gmail.com2024-09-07T06:29:52Zurn:sha1:b90cd9bd45322c103433e97e775e88991930313c
When the DB4 instruction is evaluated, a single '.' character will be
printed to stdout if the return stack is empty and the working stack
contains a single 0xff byte, otherwise a single 'X' character will be
printed to stdout.
This is to facilitate unit testing the instruction set with a Bedrock
program, from within the emulator.

The most recently closed directory listing is cached instead of being
discarded. The next time a directory is to be opened, if the file path
is the same as the cached directory, the cached directory listing is
used in order to save the entire listing from having to be regenerated.
This is expected to result in performance gains on Windows.
Prevent unused variable warning on Linux2024-08-11T00:38:13ZBen Bridlebridle.benjamin@gmail.com2024-08-11T00:38:13Zurn:sha1:68f633f6ba35a4fbbae9ed22fc759ce3544f6a0e
The base variable is only used when compiling on Windows, so an
unused variable warning is raised when compiling on Linux.
