Previously we had the invariant that if we had a server monitor, we also
had a terminal. When a monitor shrank into a place, we deleted the
monitor, and then recreated it when a peripheral was requested.
As of ab785a0906 this has changed
slightly, and we now just delete the terminal (keeping the ServerMonitor
around). However, we didn't adjust the peripheral code accordingly,
meaning we didn't recreate the /terminal/ when a peripheral was
requested.
The fix for this is very simple - most of the rest of this commit is
some additional code for ensuring monitor invariants hold, so we can
write tests with a little more confidence.
I'm not 100% sold on this approach. It's tricky having a double layer of
nullable state (ServerMonitor, and then the terminal). However, I think
this is reasonable - the ServerMonitor is a reference to the multiblock,
and the Terminal is part of the multiblock's state.
Even after all the refactors, monitor code is still nastier than I'd
like :/.
Fixes#1608
Currently redirects would be returned from the proxy, and then
immediately followed by XMLHTTPRequest. The proxy now follows requests
(when requested), so that should no longer happen.
We should probably switch over to fetch(...) here, to allow setting
follow_redirects to false, but that's a job for another day.
Haha, so many web emulator related commits of late. This'll die down
soon.
We can't use FriendlyByte.readCollection to read to a
pre-allocated/array-backed NonNullList, as that doesn't implement
List.add. Instead, we just need to do a normal loop.
We add a couple of tests to round-trip our recipe specs. Unfortunately
we can't test the recipes themselves as our own registries aren't set
up, so this'll have to do for now.
- Update to Rollup 4.x
- Replace terser and postcss with swc and lightningcss. This is
definitely more code for us to write (maybe I should turn them into
proper plugins we can depend on), but both speedier and fewer
dependencies.
- Drop dependency on glob - we can get away with fs.readdir for what we
needed it for.
Oh, this was a really nasty bug to reproduce. I'm not sure why - it's
very simple - I guess I've only just seen screenshots of it, and never
sat down to try myself. Reminder to actually report your bugs folks!
In this case:
1. Place down three down three monitors and then a computer.
2. Display something on the monitor (monitor left paint a) is my go-to.
3. Break the middle monitor.
We'd expect the left most monitor to be cleared, however it actually
preserves the monitor contents, resizing (and skewing it) to fit on its
new size!
This is because we clear the server monitor, but never sync that over to
the client, so the client monitor retains the old contents. To fix that,
instead of nulling out the server monitor, we null out the underlying
Terminal. This causes the change to be synced, fixing the bug.
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.

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.
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.
This made more sense on 1.19.2 and before, but now that we have to do
this for tooltips, we might as well do it for messages as well.
Closes#1538, though hopefully will be resolved on the VO side too.
- Remove some unused translation keys.
- Run tools/language.py to sort the current translations and remove the
aforementioned unused keys.
- Update turtle tool impostor recipes - these now include the tool NBT!

- Move the tool action before the "is block present" check, fixes
#1527. This is where it was before, but we flipped it around in the
tool rewrite.
- Don't reuse as much turtle.place logic for tool actions. This fixes
some instances where tools could till/level dirt through solid
blocks.
- Overhaul model loading to work with the new API. This allows for
using the emissive texture system in a more generic way, which is
nice!
- Convert some of our custom models to use Fabric's model hooks (i.e.
emitItemQuads). We don't make use of this right now, but might be
useful for rendering tools with enchantment glints.
Note this does /not/ change any of the turtle block entity rendering
code to use Fabric/Forge's model code. This will be a change we want
to make in the future.
- Some cleanup of our config API. This fixes us printing lots of
warnings when creating a new config file on Fabric (same bug also
occurs on Forge, but that's a loader problem).
- Fix a few warnings
We've supported resource conditions in the upgrade JSON for an age, but
don't expose it in our data generators at all.
Indeed, using these hooks is a bit of a pain to do in multi-loader
setups, as the JSON is different between the two loaders. We could
generate the JSON for all loaders at once, but it feels nicer to use
the per-loader APIs to add the conditions.
For now, we just support generating a single condition - whether a mod
is loaded not, via the requireMod(...) method.
We were generating methods with the original object, rather than the
extra one.
Updated our tests to actually catch this. Unfortunately the only places
we use this interface is in HTTP responses and transferred files,
neither of which show up in the Lua-side tests.
We switched to Forge's loot modifier system in the 1.20 update, as
LootTable.addPool had been removed. Turns out this was by accident, and
so we switch back to the previous implementation, as it's much simpler
and efficient.
- Attach permission checks to the first argument (so the literal
command name) rather than the last argument. This fixes commands
showing up when they shouldn't.
- HelpingArgumentBuilder now inherits permissions of its leaf nodes.
This only really impacts the "track" subcommand.
- Don't autocomplete the computer selector for the "queue" subcommand.
As everyone has permission for this command, it's possible to find
all computer ids and labels in the world.
I'm in mixed minds about this, but don't think this is an exploit -
computer ids/labels are sent to in-range players so shouldn't be
considered secret - but worth patching none-the-less.
- Document that settings.set doesn't persist values. I think this
closes#1512 - haven't heard back from them.
- Add missing close reasons to the websocket_closed event. Closes#1493.
- Mention what values are preserved by os.queueEvent. This is just the
same as modem.transmit. Closes#1490.
- Normalise upgrade keys, to be "allowEnchantments" and
"consumeDurability". We were previously inconsistent with
allow/allows and consumes.
- Add tests for durability and enchantments of pickaxes.
- Fix a couple of issues with the original upgrade NBT being modified.
- Now store the item's tag under a separate key rather than on the
root. This makes syncing the NBT between the two much nicer.
Turtle tools now accept two additional JSON fields
- allowEnchantments: Whether items with enchantments (or any
non-standard NBT) can be equipped.
- consumesDurability: Whether durability will be consumed. This can be
"never" (the current and default behaviour), "always", and
"when_enchanted".
Closes#1501.
This is a pre-requisite for #1501, and some other refactorings I want to do.
Also fix items in the turtle upgrade slots vanishing. We now explicitly
invalidate the cache when setting the item.
I think this left over from CCTweaks or Peripheral++. It doesn't really
make sense as an API - if/when we add multiple upgrades, we'll want a
different API for this.
This removes a tiny bit of duplication (at the cost of mode code), but
makes the interface more intuitive, as there's no bouncing between
getCombination -> cache -> buildModel.
It turns out we don't document the "port" option anywhere, so probably
worth doing a bit of an overhaul here.
- Expand the top-level HTTP rules comment, clarifying how things are
matched and describing each field.
- Improve the comments on the default HTTP rule. We now also describe
the $private rule and its motivation.
- Don't drop/ignore invalid rules. This gets written back to the
original config file, so is very annoying! Instead we now log an
error and convert the rule into a "deny all" rule, which should make
it obvious something is wrong.
- Remove the "force_print" code. This is a relic of before we used
table.pack, and so didn't know how many expressions had been
returned.
- Check the input string is a valid expression separately before
wrapping it in an _echo(...). Fixes#1506.
- Update to Loom 1.2 and FG 6.0. ForgeGradle has changed how it
generates the runXyz tasks, which makes running our tests much
harder. I've raised an issue upstream, but for now we do some nasty
poking of internals.
- Fix Sodium/Iris tests. Loom 1.1 changed how remapped configurations
are generated - we create a dummy source set and associate the
remapped configuration with that. All nasty stuff.
- Publish the common library. I'm not a fan of this, but given how much
internals I'm poking elsewhere, should probably get off my high
horse.
- Add renderdoc support to the client gametests, enabled with
-Prenderdoc.
- Fix mainThread=true methods calling IArguments.escapes too late. This
should be done before scheduling on the main thread, not on the main
thread itself!
- Fix VarargsArguments.escapes not checking that the argument haven't
been closed. This is slightly prone to race conditions, but I don't
think it's worth the overhead of tracking the owning thread.
Maybe when panama and its resource scopes are released.
Thanks Sara for pointing this out!
Slightly irked that none of our tests caught this. Alas.
Also fix a typo in AddressPredicate. Yes, no commit discipline.
- Move the class cache out of Generator into MethodSupplierImpl. This
means we cache class generation globally (that's really expensive!),
but the class -> method list lookup is local.
- Move the global GenericSource/GenericMethod registry out of core,
passing in the list of generic methods to the ComputerContext.
I'm not entirely thrilled by the slight overlap of MethodSupplierImpl and
Generator here, something to clean up in the future.
- Move several interfaces out of `d00.computercraft.core.asm` into a
new `aethods` package. It may make sense to expose this to the
public API in a future commit (possibly part of #1462).
- Add a new MethodSupplier<T> interface, which provides methods to
iterate over all methods exported by an object (either directly, or
including those from ObjectSources).
This interface's concrete implementation (asm.MethodSupplierImpl),
uses Generators and IntCaches as before - we can now make that all
package-private though, which is nice!
- Make the LuaMethod and PeripheralMethod MethodSupplier local to the
ComputerContext. This currently has no effect (the underlying
Generator is still global), but eventually we'll make GenericMethods
non-global, which unlocks the door for #1382.
- Update everything to use this new interface. This is mostly pretty
sensible, but is a little uglier on the MC side (especially in
generic peripherals), as we need to access the global ServerContext.
- Remove SidedGenericPeripheral (we never used this!), adding the
functionality to GenericPeripheral directly. This is just used on the
Fabric side for now, but might make sense with Forge too.
- Move GenericPeripheralBuilder into the common project - this is
identical between the two projects!
- GenericPeripheralBuilder now generates a list of methods internally,
rather than being passed the methods.
- Add a tiny bit of documentation.
