This means the config is no longer stored as static fields, which is a
little cleaner. Would like to move everything else in the future, but
this is a good first step.
We could do this in a more concise manner by wrapping Throwable rather
than reimplementing printStackTrace. However, doing this way allows us
to handle nested exceptions too.
Modrinth proxies images hosted on non-trusted domains through wsrv.nl,
for understandable reasons. However, wsrv.nl blocks tweaked.cc - I'm not
sure why. Instead we reference the image on GH directly, which works!
Also:
- Fix the modrinthSyncBody task pointing to a missing file.
- Update the licenses of a few files, post getting permission from
people. <3 all.
- Add a `timeout` parameter to http request and websocket methods.
- For requests, this sets the connection and read timeout.
- For websockets, this sets the connection and handshake timeout.
- Remove the timeout config option, as this is now specified by user
code.
- Use netty for handling websocket handshakes, meaning we no longer
need to deal with pongs.
In this case, we use Lua's tostring(x) semantics (well, modulo
metamethods), instead of Java's Object.toString(x) call. This ensures
that values are formatted (mostly) consistently between Lua and Java
methods.
- Add IArguments.getStringCoerced, which uses Lua's tostring semantics.
- Add a Coerced<T> wrapper type, which says to use the .getXCoerced
methods. I'm not thrilled about this interface - there's definitely
an argument for using annotations - but this is probably more
consistent for now.
- Convert existing methods to use this call.
Closes#1445
This is a horrible commit: It's a breaking change in a pretty subtle
way, which means it won't be visible while updating. Fortunately I think
the only mod on 1.19.4 is Plethora, but other mods (Mek, Advanced
Peripherals) may be impacted when they update. Sorry!
For some motivation behind the original issue:
The default IArguments implementation (VarargArguments) lazily converts
Lua arguments to Java ones. This is mostly important when passing tables
to Java functions, as we can avoid the conversion entirely if the
function uses IArguments.getTableUnsafe.
However, this lazy conversion breaks down if IArguments is accessed on a
separate thread, as Lua values are not thread-safe. Thus we need to
perform this conversion before the cross-thread sharing occurs.
Now, ideally this would be an implementation detail and entirely
invisible to the user. One approach here would be to only perform this
lazy conversion for methods annotated with @LuaFunction(unsafe=true),
and have it be eager otherwise.
However, the peripheral API gets in the way here, as it means we can no
longer inspect the "actual" method being invoked. And so, alas, this
must leak into the public API.
TLDR: If you're getting weird errors about scope, add an
IArguments.escapes() call before sharing the arguments between threads.
Closes#1384
- Fix several inaccuracies with several files not marking Dan's
authorship. Most of these are new files, where the code was moved from
somewhere else:
- In the public API: IDynamicLuaObject, ILuaAPI, TaskCallbakc,
IDynamicPeripheral, UpgradeBase
- In the ROM: fs, http, require
- Do not mark Dan as an author for entirely new code. This affects
DetailHelpers, DropConsumer, FluidData, InventoryMethods, ItemDetails,
MonitorRenderState, NoTermComputerScreen, Palette, PlatformHelperImpl,
UploadFileMessage, the Terminal tests, and any speaker-related files.
- Relicence many files under the MPL where we have permission to do
so. See #1339 for further details.
Thank you to everyone who has contributed so far! Cannot overstate how
appreciated it is <3.
- Consult __name in native code too. Closes#1355. This has the added
advantage that unconvertable values (i.e. functions) will now
correctly be reported as their original type, not just nil.
- Fix the error message in cc.expect, so it matches the rest of Lua.
This has been bugging me for years, and I keep forgetting to change
it.
- Several files where @MCJack123 is the exclusive contributor. He has
signed over all contributions to "any OSI-approved license". Thank
you!
- Various the file handle classes: Looking at these again, I don't
think they contain any of the original code.
- Timeouts are now driven by an interrupt system, rather than polling.
While we do not impose memory limits, this should close#1333.
- Update the table library to largely match Lua 5.4:
- Add table.move
- Table methods (with the exception of foreach/foreachi) now use
metamethods (closes#1088).
There's still some remaining quirks (for instance, table.insert
accepts values out-of-bounds), but I think that's fine.
- Cobalt's threaded-coroutine system is gone (load now supports
yielding), so we no longer track coroutine metrics.
- Type errors now use __name. See #1355, though this does not apply to
CC methods (either on the Java or CraftOS side), so is not enough to
resolve it.
See https://github.com/SquidDev/Cobalt/compare/v0.6.0...v0.7.0 for the
full delta.
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.

Given an input like f(x), which is both a valid statement and
expression, both parsers would accept the whole input. However, this was
treated the same as both parsers rejecting the input, resulting in a
crash when trying to print the error.
We now return immediately when any parser accepts the input.
Fixes#1354
If someone had a recursive table (created with an IIFE), then we'd throw
an error inside reserialize. We now catch this error and silently drop
the value.
I'm not thrilled by this behaviour - there's an argument we should
return false instead - but it's consistent with what we currently do.
Closes#1337.
Woops!
- Fix the REPL not printing values, as exception.try didn't return
values. It did originally, and then I tried to simplify it >_>
- Change repl_exprs to run an expression and program parser in
parallel, rather than handling the parallelism on the grammar side -
that has a few shift/reduce conflicts which result in bad parse
errors.
- Bump Cobalt to 0.6.0. We now track both line and column numbers of
each bytecode instruction, allowing us to map an error to a concrete
position.
- `loadfile` (and similar functions) now use the full path, rather than
the file name. Cobalt truncates this to 30 characters (rather than
the previous 60) so this should be less noisy.
- The shell, edit and Lua REPL now display the corresponding source
code alongside an error.
Note this is incredibly limited right now - it won't cope with errors
which cross coroutine boundaries. Supporting this is on the roadmap,
but requires some careful API design.
- Encode the DFA as a virtual machine (identical to lrgrep) rather than
compiling it to a series of Lua functions. While this is a little
slower and uglier, it's much more space efficient, shaving off 16Kb.
- Minimise the DFA properly. This only shaves off a few states, but
every little helps.
- Run the error handling code from a non-reduced parser stack. This was
incredibly nasty to get right (and positions are still not correctly
handled), but it fixes several broken error messages.
- Add several (internal) modules for lexing and parsing Lua code. These
allow us to provide (hopefully) higher quality error messages than
Lua's built-in messages.
- `shell.run`, `edit` and `lua` now use this parser when fed invalid
code. This allows us to provide better syntax errors, while not
having any impact on the happy path.
Note this does not affect any other mechanism for loading code
(`load`, `require`, `dofile`).
There's still a lot of work to do here in improving error message
quality, but hopefully this provides a good starting point.
Just ran[^1] over the codebase. Turns out we'd duplicated one of the
changelog entries entirely - I suspect due to a version merge gone
wrong!

I've been meaning to fix this for over 6 years, and just kept
forgetting.
Previously ILuaContext.executeMainThreadTask worked by running
ILuaContext.issueMainThreadTask, pulling task_complete events, and then
returning the results.
While this makes the implementation simple, it means that the task's
results were converted into Lua values (in order to queue the event) and
then back into Java ones (when the event was pulled), before eventually
being converted into Lua once more.
Not only is this inefficient, as roundtripping isn't lossless, you
couldn't return functions or rich objects from main thread functions
(see https://github.com/dan200/ComputerCraft/issues/125).
We now store the return value on the Java side and then return that when
the receiving the task_complete event - the event no longer carries the
result. Note this does not affect methods using issueMainThreadTask!
- Separate FileMount into separate FileMount and WritableFileMount
classes. This separates the (relatively simple) read-only code from
the (soon to be even more complex) read/write code.
It also allows you to create read-only mounts which don't bother with
filesystem accounting, which is nice.
- Make openForWrite/openForAppend always return a SeekableFileHandle.
Appendable files still cannot be seeked within, but that check is now
done on the FS side.
- Refactor the various mount tests to live in test contract interfaces,
allowing us to reuse them between mounts.
- Clean up our error handling a little better. (Most) file-specific code
has been moved to FileMount, and ArchiveMount-derived classes now
throw correct path-localised exceptions.
- Flip http.websocket and http.websocketAsync docs (fixes#1244)
- Fix http.request queuing a http_failure event with no URL when
passing a malformed URL
- Fix http.websocketAsync not queuing websocket_failure events on
immediate failure.
In classic squid tradition: 20% code, and 80% test logic.
Closes#962. Alas, whoever reported this has deleted their account, so
they can't even be happy about it :(.
- 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.
I kinda hate this, but not sure what else to do. It might be worth
rewriting sanitizePath in the future to loop through the string once,
but I think this is good enough for now.
