Paint implements its menu slightly differently to edit, in that it takes
control of the event loop until the menu is closed. This means that the
term_resize event is ignored, and so the canvas not redrawn when the
menu is open.
Historically we've used copy-cat to provide a web-based emulator for
running example code on our documentation site. However, copy-cat is
often out-of-date with CC:T, which means example snippets fail when you
try to run them!
This commit vendors in copy-cat (or rather an updated version of it)
into CC:T itself, allowing us to ensure the emulator is always in sync
with the mod.
While the ARCHITECTURE.md documentation goes into a little bit more
detail here, the general implementation is as follows
- In project/src/main we implement the core of the emulator. This
includes a basic reimplementation of some of CC's classes to work on
the web (mostly the HTTP API and ComputerThread), and some additional
code to expose the computers to Javascript.
- This is all then compiled to Javascript using [TeaVM][1] (we actually
use a [personal fork of it][2] as there's a couple of changes I've
not upstreamed yet).
- The Javascript side then pulls in the these compiled classes (and
the CC ROM) and hooks them up to [cc-web-term][3] to display the
actual computer.
- As we're no longer pulling in copy-cat, we can simplify our bundling
system a little - we now just compile to ESM modules directly.

Had an issue last week where testFixtures had a couple of issues which I
didn't pick up on, as the pre-commit hooks only check the main and test
source set.
We now add a per-project "checkstyle" task, which dependes on the
per-source-set checkstyle tasks.
This moves MemoryMount to the main core module, and converts it to be a
"proper" WritableMount. It's still naively implemented - definitely
would be good to flesh out our tests in the future - but enough for what
we need it for.
We also do the following:
- Remove the FileEntry.path variable, and instead pass the path around
as a variable.
- Clean up BinaryReadableHandle to use ByteBuffers in a more idiomatic
way.
- Add a couple more tests to our FS tests. These are in a bit of an odd
place, where we want both Lua tests (for emulator compliance) and
Java tests (for testing different implementations) - something to
think about in the future.
- Move the frontend code into src/frontend
- Move our custom element SSR system into src/htmlTransform.
This is mostly in prep for merging in copy-cat's core, as that's a whole
bunch of extra code.
This attempts to reduce some duplication in recipe serialisation (and
deserialisation) by moving the structure of a recipe (group, category,
ingredients, result) into seprate types.
- Add ShapedRecipeSpec and ShapelessRecipeSpec, which store the core
properties of shaped and shapeless recipes. There's a couple of
additional classes here for handling some of the other shared or
complex logic.
- These classes are now used by two new Custom{Shaped,Shapeless}Recipe
classes, which are (mostly) equivalent to Minecraft's
shaped/shapeless recipes, just with support for nbt in results.
- All the other similar recipes now inherit from these base classes,
which allows us to reuse a lot of this serialisation code. Alas, the
total code size has still gone up - maybe there's too much
abstraction here :).
- Mostly unrelated, but fix the skull recipes using the wrong UUID
format.
This allows us to remove our mixin for nbt in recipes (as we just use
our custom recipe now) and simplify serialisation a bit - hopefully
making the switch to codecs a little easier.
- Add AbstractInMemoryMount, which contains all of ArchiveMount's file
tree logic, but not the caching functionality.
- Convert MemoryMount to inherit from AbstractInMemoryMount.
- Add a helper method to add a file to an AbstractInMemoryMount, and
use that within {Resource,Jar}Mount.
There's definitely more work to be done here - it might be nice to split
FileEntry into separate Directory and File interfaces, or at least make
them slightly more immutable, but that's definitely a future job.
- Add a new WebsocketClient interface, which WebsocketHandle uses for
sending messages and closing. This reduces coupling between Websocket
and WebsocketHandle, which is nice, though admitedly only use for
copy-cat :).
- WebsocketHandle now uses Websocket(Client).isClosed(), rather than
tracking the closed state itself - this makes the class mostly a thin
Lua wrapper over the client, which is nice.
- Convert Options into a record.
- Clarify the behaviour of ws.close() and the websocket_closed event.
Our previous test was incorrect as it called WebsocketHandle.close
(rather than WebsocketHandle.doClose), which had slightly different
semantics in whether the event is queued.
We already use preact for the copy-cat integration, so it makes sense to
use it during the static pass too. This allows us to drop a dependency
on react.
- Placing a command computer requires the player to be in creative and
opped.
- Breaking a command computer now requires the player to be opped, as
well as in creative.
As we've now got a dedicated item class for command comptuers, we move
the command-specific IMedia override to that class.
Fixes#1582.
As this is responsible for interrupting computers, we should make sure
its priority is higher than the background threads. It spends most of
its time sleeping, so should be fine.
Rather than having a mess of lambdas, we now move the bulk of the
implemetation to their own methods. The lambdas now just do argument
extraction - it's all stringly typed, so good to keep that with the
argument definition.
This also removes a couple of exception keys (and thus their translation
keys) as we no longer use them.
When the target method is in a different class loader to CC, our
generated method fails, as it cannot find the target class. To get
around that, we create a MethodHandle to the target method, and then
inject that into the generated class (with Java's new dynamic constant
system). We can then invoke the MethodHandle in our generated code,
avoiding any references to the target class/method.
I removed this in aa0d544bba, way back in
late 2021. Looks like it's been updating in the meantime and I hadn't
noticed, so add it back.
I've simplified the code a little bit, to make use of our new capability
helpers, but otherwise it's almost exactly the same :D.
Wow, this is old. It looks like it's a legacy of when this method was on
TileGeneric (and so returned false by default). As all implementations
now return true (turtle tools no longer block redstone), we don't really
need this any more.
- Split buttons.png into individual textures.
- Split corners_xyz.png into the following:
- borders_xyz.png: A nine-sliced texture of the computer borders.
- pocket_bottom_xyz.png: A horizontally 3-sliced texture of the
bottom part of a pocket computer.
- sidebar_xyz.png: A vertically 3-sliced texture of the computer
sidebar.
While not splitting the sliced textures into smaller ones may seem a
little odd, it's consistent with what vanilla does in 1.20.2, and I
think will make editing them easier than juggling 9 textures.
I do want to make this more data-driven in the future, but that will
have to wait until the changes in 1.20.2.
This also adds a tools/update-resources.py program, which performs this
transformation on a given resource pack.
- Add a generic PermissionRegistry interface. This behaves similarly to
our ShaderMod interface, searching all providers until it finds a
compatible one.
We could just make this part of the platform code instead, but this
allows us to support multiple systems on Fabric, where things are
less standardised.
This interface behaves like a registry, rather than a straight
`getPermission(node, player)` method, as Forge requires us to list
our nodes up-front.
- Add Forge (using the built-in system) and Fabric (using
fabric-permissions-api) implementations of the above interface.
- Register permission nodes for our commands, and use those
instead. This does mean that the permissions check for the root
/computercraft command now requires enumerating all child
commands (and so potential does 7 permission lookups), but hopefully
this isn't too bad in practice.
- Remove UserLevel.OWNER - we never used this anywhere, and I can't
imagine we'll want to in the future.
- Support printing and parsing hex float literals
- Fix string.format "%q"'s handling of nan and inf (Kan18)
- Fix string is-letter/is-digit patterns treating characters as
unicode.
- tostring(...) now uses __name.
Should be max_websocket_message, not just websocket_message.
Also add some additional validation to address rules, to check no
unrecognised keys are present.
Closes#1566.
We're very inconsistent with whether we use locks or concurrent maps
here. Something to sort out in the future, but for now add some missing
@GuardedBy annotations.
- Prefer {read,write}Nullable when possible.
- Use SoundEvent.{writeTo,readFrom}Network, instead of sending the
registry entries. This allows playing discs which don't register
their SoundEvent on the server.
- Add a couple of tests for round-tripping these packets.
This requires supporting registries in our platform test
code. Thankfully this is mostly the same as what we can do in Fabric -
the duplication is unfortunate - but it's easy enough.
I want to write some tests to check that various packets round-trip
corretly. However, these packets don't (and shouldn't) implement
.equals, and so we need a more reflective(/hacky) way of comparing them.
