I didn't make a new years resolution to stop writing build tooling, but
maybe I should have.
This replaces our use of VanillaGradle with a new project,
VanillaExtract. This offers a couple of useful features for multi-loader
dev, including Parchment and Unpick support, both of which we now use in
CC:T.
Does it count as an emulator when it's official? I hope not, as this'd
make it my fourth or fifth emulator at this point.

Developing/debugging CraftOS is a massive pain to do inside Minecraft,
as any change to resources requires a compile+hot swap cycle (and
sometimes a `/reload` in-game). As such, it's often more convenient to
spin up an emulator, pointing it to load the ROM from CC:T's sources.
However, this isn't practical when also making changes to the Java
classes. In this case, we either need to go in-game, or build a custom
version of CCEmuX.
This commit offers an alternative option: we now have our own emulator,
which allows us to hot swap both Lua and Java to our heart's content.
Most of the code here is based on our monitor TBO renderer. We probably
could share some more of this, but there's not really a good place for
it - feels a bit weird just to chuck it in :core.
This is *not* a general-purpose emulator. It's limited in a lot of
ways (won't launch on Mac[^1], no support for multiple computers) - just
stick to what's there already.
[^1]: We require OpenGL 4.5 due to our use of DSA.
This adds SPDX license headers to all source code files, following the
REUSE[1] specification. This does not include any asset files (such as
generated JSON files, or textures). While REUSE does support doing so
with ".license" files, for now we define these licences using the
.reuse/dep5 file.

- Remove deprecated API members in prep for 1.19.3. This allows us to
remove the mc-stubs and forge-stubs projects.
- Make several methods take a MinecraftServer instead of a Level (or
nothing at all).
- Remove I prefixes from a whole bunch of interfaces, making things a
little more consistent with Java conventions.
This avoids touching the "main" interfaces people consume for now. I
want to do that another Minecraft version, to avoid making the update
too painful.
- Remove IFileSystem and associated getters. This has never worked very
well and I don't think has got much (any?) usage.
- Add support for Fabric. This is mostly pretty simple, though does
require a lot more mixins than Forge.
Half this diff is due to data generators: we run them separately as
some aspects (recipes mostly) are different between the loaders.
- Add integration with Iris (same as our Oculus support) and REI
(mostly the same as our JEI support).
- Generic peripherals only support inventories (or rather
InventoryStorage) right now. Supporting more of the Fabric storage
API is going to be tricky due to the slotted nature of the API: maybe
something to revisit after Transfer API V3 (V4?, I've lost track).
Note, this does /not/ mean I will be publishing a Fabric version of
CC:T. My plan is to rebase CC:R on top of this, hopefully simplifying
the maintenance work on their end and making the two mods a little more
consistent.
After several weeks of carefully arranging ribbons, we pull the string
and end up with, ... a bit of a messy bow. There were still some things
I'd missed.
- Split the mod into a common (vanilla-only) project and Forge-specific
project. This gives us room to add Fabric support later on.
- Split the project into main/client source sets. This is not currently
statically checked: we'll do that soon.
- Rename block/item/tile entities to use suffixes rather than prefixes.
This adds two new modules: common-api and forge-api, which contain the
common and Forge-specific interfaces for CC's Minecraft-specific API.
We add a new PlatformHelper interface, which abstracts over some of the
loader-specific functionality, such as reading registries[^1] or calling
Forge-specific methods. This interface is then implemented in the main
mod, and loaded via ServiceLoaders.
Some other notes on this:
- We now split shared and client-specific source code into separate
modules. This is to make it harder to reference client code on the
server, thus crashing the game.
Eventually we'll split the main mod up too into separate source sets
- this is, of course, a much bigger problem!
- There's currently some nastiness here due to wanting to preserve
binary compatibility of the API. We'll hopefully be able to remove
this when 1.19.3 releases.
- In order to build a separate Forge-specific API jar, we compile the
common sources twice: once for the common jar and once for the Forge
jar.
Getting this to play nicely with IDEs is a little tricky and so we
provide a cct.inlineProject(...) helper to handle everything.
[^1]: We /can/ do this with vanilla's APIs, but it gives a lot of
deprecation warnings. It just ends up being nicer to abstract over it.
It should be possible to consume the ComputerCraft's core (i.e.
non-Minecraft code) in other projects, such as emulators. While this
has been possible for years, it's somewhat tricky from a maintenance
perspective - it's very easy to accidentally add an MC dependency
somewhere!
By publishing a separate "core" jar, we can better distinguish the
boundaries between our Lua runtime and the Minecraft-specific code.
Ideally we could have one core project (rather than separate core and
core-api modules), and publish a separate "api" jar, like we do for the
main mod. However, this isn't really possible to express using Maven
dependencies, and so we must resort to this system.
Of course, this is kinda what the Java module system is meant to solve,
but unfortunately getting that working with Minecraft is infeasible.
- Add a new Node plugin. This automatically installs npm dependencies
and provides a "NpxExecToDir" to dir task. This allows us to make the
doc website task dependencies a little nicer, by simply chaining
tasks together, rather than doing dependsOn + `input.files(the other
task output)`.
- Switch over to CurseForgeGradle from CurseGradle. The latter is
super clunky to use in non-Groovy languages.
- Copy our Modrinth description body to our repo, and add support for
syncing it. We'll still have to do CF manually I think.
It's more verbose as the default license plugin doesn't support multiple
license headers. However, it also gives us some other goodies (namely
formatting Kotlin and removing unused imports), so worth doing.
- Switch to plugins { ... } imports for Forge (FG finally supports it!)
- Use FG's new fg.component to clean up our Maven metadata instead. We
also mark JEI as optional (using Gradle's registerFeature), which
means we've no stray deps inside our POM any more.
