42a3dd24ad Put some braces back
These blocks were not strictly needed but helped readability. I didn't
mean for the reformatter to change them while dealing with the "this"
problem. It also removed some braces in switch statements but who cares.

06b0538b76 Reverted change to blocker layer, with tweaks.
Without the blocker layer even VBOs didn't work with shaders. So instead
I put the blocker back and made it mask both color and depth buffers,
which fixes the bug with chests and water drawing over monitors. Since
it now masks color I hoisted it up to be drawn before the terminal, and
made the terminal slightly offset to solve z-fighting with VBO renderer.

f3d22444d3 Fix: Stop water and chests being drawn over monitors
Somewhere along the line the gl state was being mangled and I'm still
not sure where! I moved the monitor blocks from the cutout render layer
to the default solid layer, which obviates the depth blocker. I don't
think the transparent front of the monitor blocks was ever visible so
this should be fine. Then the terminal quads are moved slightly outward
to prevent z-fighting with the now present block front.

Finally I noticed some chests were not rendering correctly around
monitors, so I paired an endDrawing() call with our sneaky hack of
calling startDrawing() to force the rendering state. This fixed the
chests. Hopefully we haven't messed up the render state in more ways :)

b0d7f690eb Fix: Mimic CC:T config file structure
Replaces the jankson implementation with night-config. Night config is
what the forge api uses so it's easy to produce .toml files in the same
structure as CC:Tweaked.

All config options and comments from CC:Tweaked are implemented. Some
of these options are ignored in various bits of implementation but that
is another problem :)

Also splits the config into a client and server file. The server file is
saved per-world. Names and locations are consistent with CC:T.

1f117b7c47 Fix: Inform block entities when chunk is unloaded.
Forge's ITileEntity interface adds a onChunkUnloaded handler method into
block entities. The fabric port doesn't have a re-implementation of this
feature, which meant TileMonitors weren't releasing their buffers when
unloaded. This commit adds that handler method back into TileGeneric,
which all CC block entities inherit from. Handler logic for the four
block entities that use this feature were copied over from the forge
repo.

c820e051b3 Fix: Release monitor buffers on *client* thread
These buffers were being released on the server thread, causing the
logical server in a single player session to crash just before shutting
down. It seems the crash happened late enough to not cause world
corruption issues, and so went unnoticed. It was however causing a
memory leak when quitting/rejoining worlds, and it left the save file
lock in limbo.

on the client side and use that to open the folder.

Also make the example a bit more "useful". Hopefully this should clarify
that the function returns a table rather than a single string.

094e0d4f33 Fix mounts being usable after a disk is ejected
This probably fails "responsible disclosure", but it's not an RCE and
frankly the whole bug is utterly hilarious so here we are...

It's possible to open a file on a disk drive and continue to read/write
to them after the disk has been removed:

    local disk = peripheral.find("drive")
    local input = fs.open(fs.combine(disk.getMountPath(), "stream"), "rb")
    local output = fs.open(fs.combine(disk.getMountPath(), "stream"), "wb")
    disk.ejectDisk()

    -- input/output can still be interacted with.

This is pretty amusing, as now it allows us to move the disk somewhere
else and repeat - we've now got a private tunnel which two computers can
use to communicate.

Fixing this is intuitively quite simple - just close any open files
belonging to this mount. However, this is where things get messy thanks
to the wonderful joy of how CC's streams are handled.

As things stand, the filesystem effectively does the following flow::
 - There is a function `open : String -> Channel' (file modes are
   irrelevant here).

 - Once a file is opened, we transform it into some <T extends
   Closeable>. This is, for instance, a BufferedReader.

 - We generate a "token" (i.e. FileSystemWrapper<T>), which we generate
   a week reference to and map it to a tuple of our Channel and T. If
   this token is ever garbage collected (someone forgot to call close()
   on a file), then we close our T and Channel.

 - This token and T are returned to the calling function, which then
   constructs a Lua object.

The problem here is that if we close the underlying Channel+T before the
Lua object calls .close(), then it won't know the underlying channel is
closed, and you get some pretty ugly errors (e.g. "Stream Closed"). So
we've moved the "is open" state into the FileSystemWrapper<T>.

The whole system is incredibly complex at this point, and I'd really
like to clean it up. Ideally we could treat the HandleGeneric as the
token instead - this way we could potentially also clean up
FileSystemWrapperMount.

BBut something to play with in the future, and not when it's 10:30pm.

All this wall of text, and this isn't the only bug I've found with disks
today :/.

d5eb82db60 Allow $private HTTP rule to block any private IP
This is a little magic compared with our previous approach of "list

Also refactor out some of the logic into separate classes, hopefully to

f1176af9d1 Make fs.combine accept multiple arguments
Means we can now do fs.combine("a", "b", "c"). Of course, one may just
write "a/b/c" in this case, but it's definitely useful elsewhere.

This is /technically/ a breaking change as fs.combine(a, b:gsub(...))
will no longer function (as gsub returns multiple arguments). However,
I've done a quick search through GH and my Pastebin archives and can't
find any programs which would break. Fingers crossed.

c44c560f96 Update changelog and whatsnew
- Convert existing changelog over to use Markdown. This mostly involves

   somewhat more verbose than Dan's notes, but keeping them in sync

0cb659d78c Ensure require is usable within the REPL
As 'require' operates relative to the current program's directory,
rather than the current directory, it meant we were trying to load files
from /rom/programs.

This is never a good idea, so we add the current directory to the
package path, allowing you to use require as one'd expect.

9048deeb95 Add a function for type-checking arguments (#207)
- Define an expect(index, actual_value, types...) helper function which
   takes an argument index, value and list of permissable types and
   ensures the value is of one of those types.
   If not, it will produce an error message with the expected and actual
   type, as well as the argument number and (if available) the function
   name.
 - Expose expect in the global scope as _G["~expect"], hopefully making
   it clear it is internal.
 - Replace most manual type checks with this helper method.
 - Write tests to ensure this argument validation works as expected

Also fix a couple of bugs exposed by this refactor and the subsequent
tests:
 - Make rednet checks a little more strict - rednet.close(false) is no
   longer valid.
 - Error when attempting to redirect the terminal to itself 
   (term.redirect(term)).

   /fine/, but there's better channels for it!
 - Add a couple of PR templates
   - Ask people to write tests for CraftOS changes. This is a standard
     I'm trying to impose on myself, so seems reasonable to impose on
     everyone. Sorry!
   - Require same levels of explanation for PRs as we do for issues.
 - Try to expand on the feature request "rationale" section a little.

114f913bf8 Rework rendering of in-hand pocket computers (#215)
Rendering an item worked in principle, but had several caveats:
 - The terminal did not fit well within the item's texture, so we had a
   rather large border.
 - The "correctness" of this was very tied to Minecraft's item rendering
   code. This changed a little in 1.13, causing problems like #208.

Instead we effectively reuse the computer GUI rendering code, though
also handling coloured pocket computers and rendering the modem light.

This fixes #208, and hopefully fixes #212.

210f3fa9e2 Add mostly standard compliant os.time/os.date
- os.time, when given a table, will act the same as PUC Lua - returning
   the seconds since the epoch. We preserve the previous string/nil
   behaviour though - os.epoch("local") is equivalent to PUC's
   os.time().

 - os.date will now act accept a string and (optional) time, returning
   an appropriate table.

Somewhat resolves the madness which was dan200/ComputerCraft#183, and
hopefully (though probably not) makes @Vexatos happy.

0ec3884e98 Handle websockets which close while receiving
This changes the previous behaviour a little, but hopefully is more
sane:

 - Only require the socket to be open when first calling receive. This
   means if it closes while receving, you won't get an error.

   This behaviour is still not perfect - the socket could have closed,
   but the event not reached the user yet, but it's better.

 - Listen to websocket_close events while receiving, and return null
   should it match ours.

8fafec4915 Fix budget growing too much
We were using += instead of =, meaning the budget always grew,
rather than growing while there was still space. As a result, computers
were never correctly rate limited.

Further more, if a computer went into a deficit, we would continue to
increase the budget by a negative amount, exponentially decreasing until
overflowing!

Yes, this is a very embarrassing mistake. I'd been aware that rate
limiting wasn't working as expected for a while, I hadn't realised
the problem would be this stupid.

7071cc972b Make redstone behaviour consistent with repeaters
This uses the same behaviour that repeaters and comparators do for

It's worth noting that this is a shift from previous behaviour.
Therefore, it runs the (small) risk of breaking existing builds.

f9e13ca67a Update CC: Tweaked to 1.13
Look, I originally had this split into several commits, but lots of
other cleanups got mixed in. I then backported some of the cleanups to
1.12, did other tidy ups there, and eventually the web of merges was
unreadable.

Yes, this is a horrible mess, but it's still nicer than it was. Anyway,
changes:

 - Flatten everything. For instance, there are now three instances of
   BlockComputer, two BlockTurtle, ItemPocketComputer. There's also no
   more BlockPeripheral (thank heavens) - there's separate block classes
   for each peripheral type.

 - Remove pretty much all legacy code. As we're breaking world
   compatibility anyway, we can remove all the code to load worlds from
   1.4 days.
 - The command system is largely rewriten to take advantage of 1.13's
   new system. It's very fancy!

 - WidgetTerminal now uses Minecraft's "GUI listener" system.

 - BREAKING CHANGE: All the codes in keys.lua are different, due to the
   move to LWJGL 3. Hopefully this won't have too much of an impact.

   I don't want to map to the old key codes on the Java side, as there
   always ends up being small but slight inconsistencies. IMO it's
   better to make a clean break - people should be using keys rather
   than hard coding the constants anyway.

 - commands.list now allows fetching sub-commands. The ROM has already
   been updated to allow fancy usage such as commands.time.set("noon").

 - Turtles, modems and cables can be waterlogged.

 - Expose Abstract*Upgrade classes in the API
 - Fix the spelling of Jonathan in the API docs (*shakes fist*)
 - Fix bug with printout not working in the offhand.

   durability instead.

   would clear the name, this seemed a little unideal).
 - commands.getBlock(s)Data will also include NBT.

Now, onto the horror story which is these inspection changes:
 - Make a lot of methods static
 - Typo fixes
 - Make utility classes final + private constructor
 - Lots of reformatting (ifs -> ternary, invert control flow, etc...)
 - ???

This effectively acts as a public interface to canExecuteExternal() and

One thing to note here is that this is based on a polling API, as it's
largely intended for people running work every tick. It would be
possible to adapt this with callbacks for when work is available,
etc..., but that was not needed immediately.

This also removes IComputerOwned, as Plethora no longer needs it.

853e2622a1 An initial prototype of main thread rate limiting
Unlike ComputerThread, we do not have a single source of tasks, and so
need a smarter way to handle scheduling and rate limiting. This
introduces a cooldown system, which works on both a global and
per-computer level:

Each computer is allowed to do some work for 5ms. If they go over that
budget, then they are marked as "hot", and will not execute work on the
next tick, until they have cooled down. This ensures that _on average_
computers perform at most 5ms of work per tick.

Obviously this is a rather large time span, so we also apply a global
10ms to all computers. This uses the same cooldown principle, meaning we
keep to an average of 10ms, even if we go over budget.

Before IPocketAccess.getEntity would return the entity which last held

pocket.equip/pocket.unequip to dupe items.

We move the validation from the PocketAPI into the main IPocketAccess
implementation, to ensure this issue does not occur elsewhere. Note, we
require a separate method, as this is no longer thread-safe.

We also now return ok, err instead of throwing an exception, in order to

41429bdc0b Improve our JEI integration a little bit
- Turtle and pocket computers provide a "creator mod id" based on their
   upgrade(s).
   We track which mod was active when the upgrade was registered, and
   use that to determine the owner. Technically we could use the
   RegistryLocation ID, but this is not always correct (such as
   Plethora's vanilla modules).
 - We show all upgraded turtles/pocket computers in JEI now, rather than
   just CC ones.
 - We provide a custom IRecipeRegistryPlugin for upgrades, which
   provides custom usage/recipes for any upgrade or upgraded item. We
   also hide our generated turtle/pocket computer recipes in order to
   prevent duplicates.

105c66127c Automatically generate impostor recipes
Previously we would register the recipes within our code, but the
advancements were written manually. This now generates JSON files for
both the advancement and recipe.

While this does mean we're shipping even more JSON, we'll need to do
this for 1.13 anyway, and means our advancements are guaranteed to be
consistent.

On a side note, a couple of other changes:
 - Turtle upgrades are now mounted on the right in the creative
   menu/fake recipes. This means the upgrade is now clearly visible in
   the inventory.
 - We no longer generate legacy turtle items at all: we'll always
   construct turtle_expanded.
 - Several peripheral items are no longer registered as having sub-types
   (namely advanced and full-block modems).
 - We only have one disk advancement now, which unlocks all 16 recipes.
 - We have removed the disk conversion recipes - these can be
   exposed through JEI if needed.

I'd like to look into MCMP support for wired modems/cables in the

multiblock structure.

Similarly, might be fun to look into CBMP compatibility.

72d079ef61 Merge pull request #119 from SquidDev-CC/feature/computer-thread-schedule
- CobaltLuaMachine/ComputerExecutor can now be paused - this suspends 
   the machine via a debug hook. When doing work again, we resume the 
   machine, rather than starting a new task.
 - TimeoutState keeps track of how long the current execution of this task
   has gone on for, when its deadline is, and the cumulative execution time of
   this task.

f7cb526793 Attempt to fix race condition in ComputerThread
- Runners would set their active executor before starting resetting the
   time, meaning it would be judged as running and terminated.
 - Similarly, the cumulative time start was reset to 0, meaning the
   computer had been judged to run for an impossibly long time.
 - If a computer hit the terminate threshold, but not the hard abort
   one, then we'd print the stack trace of the terminated thread - we
   now do it before interrupting.

There's still race conditions here when terminating a computer, but
hopefully these changes will mean they never occur under normal
operations (only when a computer has run for far too long).

b3e6a53868 Allow pausing Lua machines
TimeoutState now introduces a TIMESLICE, which is the maximum period of
time a computer can run before we will look into pausing it.

When we have executed a task for more than this period, and if there are
other computers waiting to execute work, then we will suspend the
machine.

Suspending the machine sets a flag on the ComputerExecutor, and pauses
the "cumulative" time - the time spent handling this particular event.
When resuming the machine, we restart our timer and resume the machine.

   another Lua error), which is then shown to the user.

 - Clear the Cobalt "thrown soft abort" flag when resuming, rather than
   every n instructions.

 - Computers will clear their "should start" flag once the time has
   expired, irrespective of whether it turned on or not. Before
   computers would immediately restart after shutting down if the flag
   had been set much earlier.

d02575528b Fix leaking file descriptors when closing
When closing a BufferedWriter, we close the underlying writer. As we're
using channels, this is an instance of sun.nio.cs.StreamEncoder. This
will attempt to flush the pending character.

However, if throwing an exception within .write errors, the flush will
fail and so the underlying stream is not closed. This was causing us to
leak file descriptors.

We fix this by introducing ChannelWrappers - this holds the wrapper
object (say, a BufferedWriter) and underlying channel. When closed, we
dispose of the wrapper, and then the channel. You could think of this as
doing a nested try-with-resources, rather than a single one.

Note, this is not related to JDK-6378948 - this occurs in the underlying
stream encoder instead.

- TimeoutState uses nanoseconds rather than milliseconds. While this is

   fail to terminate computers if the time changes.
 - Add an exception handler to all threads.

06e76f9b15 Rewrite ComputerThread and the timeout system
- Instead of setting soft/hard timeouts on the ILuaMachine, we instead
   provide it with a TimeoutState instance. This holds the current abort
   flags, which can then be polled within debug hooks.

   This means the Lua machine has to do less state management, but also
   allows a more flexible implementation of aborts.

 - Soft aborts are now handled by the TimeoutState - we track when the
   task was started, and now only need to check we're more than 7s since
   then.

   Note, these timers work with millisecond granularity, rather than
   nano, as this invokes substantially less overhead.

 - Instead of having n runners being observed with n managers, we now
   have n runners and 1 manager (or Monitor).

   The runners are now responsible for pulling work from the queue. When
   the start to execute a task, they set the time execution commenced.
   The monitor then just checks each runner every 0.1s and handles hard
   aborts (or killing the thread if need be).

474f571798 Attach peripherals directly rather than deferring
Prior to this change we would schedule a new task which attached
peripherals on the ComputerThread on the empty task queue. This had a
couple of issues:
 - Slow running tasks on the computer thread could result in delays in
   peripherals being attached (technically, though rarely seen in
   practice).
 - Now that the ComputerThread runs tasks at once, there was a race
   condition in computers being turned on/off and peripherals being
   attached/detached.

Note, while the documentation said that peripherals would only be
(at|de)tached on the computer thread, wired modems would attach on the
server thread, so this was not the case in practice.

One should be aware that peripherals are still detached on the
computer thread, most notably when turning a computer on/off.

This is almost definitely going to break some less well-behaved mods,
and possible some of the well behaved ones. I've tested this on SC, so
it definitely works fine with Computronics and Plethora.

12e82afad2 Bump Cobalt version to enable single-threading
The latest version of Cobalt has several major changes, which I'm
looking forward to taking advantage of in the coming months:

 - The Lua interpreter has been split up from the actual LuaClosure
   instance. It now runs multiple functions within one loop, handling
   pushing/popping and resuming method calls correctly.

   This means we have a theoretically infinite call depth, as we're no
   longer bounded by Java's stack size. In reality, this is limited to
   32767 (Short.MAX_VALUE), as that's a mostly equivalent to the limits
   PUC Lua exposes.

 - The stack is no longer unwound in the event of errors. This both
   simplifies error handling (not that CC:T needs to care about that)
   but also means one can call debug.traceback on a now-dead coroutine
   (which is more useful for debugging than using xpcall).

 - Most significantly, coroutines are no longer each run on a dedicated
   thread. Instead, yielding or resuming throws an exception to unwind
   the Java stack and switches to a different coroutine.

   In order to preserve compatability with CC's assumption about LuaJ's
   threading model (namely that yielding blocks the thread), we also
   provide a yieldBlock method (which CC:T consumes). This suspends the
   current thread and switches execution to a new thread (see
   SquidDev/Cobalt@b5ddf164f1 for more
   details). While this does mean we need to use more than 1 thread,
   it's still /substantially/ less than would otherwise be needed.

We've been running these changes on SwitchCraft for a few days now and
haven't seen any issues. One nice thing to observe is that the number of
CC thread has gone down from ~1.9k to ~100 (of those, ~70 are dedicated
to running coroutines). Similarly, the server has gone from generating
~15k threads over its lifetime, to ~3k. While this is still a lot, it's
a substantial improvement.

0ce67afcc1 Be less strict in comparing upgrade crafting items
We currently generate the crafting item once when the upgrade is first
created, and cache it for the duration of the game. As the item never
changes throughout the game, and constructing a stack is a little
expensive (we need to fire an event, etc...), the caching is worth
having.

However, some mods may register capabilities after we've constructed our
ItemStack. This means the capability will be present on other items but
not ours, meaning they are not considered equivalent, and thus the item
cannot be equipped.

In order to avoid this, we use compare items using their share-tag, like
Forge's IngredientNBT. This means the items must still be "mostly" the
same (same enchantements, etc...), but allow differing capabilities.

See NillerMedDild/Enigmatica2Expert#655 for the original bug report -
in this case, Astral Sourcery was registering the capability in init,
but we construct upgrades just before then.

a8dad23fa3 Begin investigations into reducing ticking of TEs
- Move IDirectionalTile constraint from IPeripheralTile to

 - Make *WiredModemFull no longer inherit from *PeripheralBase. While
   there is still some shared logic (namely in the syncing of "anim"),
   it's largely fine as we don't store label or direction in NBT.
 - Add a TickScheduler. This is a thread-safe version of
   World.scheduleUpdate. We simply build a set of all TEs, and schedule
   them to be updated the next tick.
 - Make ModemState receive an "onChanged" listener, which is fired
   whenever the modem changes.
 - Make WiredModemFull no longer tick, instead scheduling updates when
   it is first loaded and whenever the modem changes.

443e0f8f76 Remove FileSystemMount and rewrite JarMount
FileSystemMount was originally added to allow using ReadableByteChannels
instead of InputStreams. However, as zip files do not allow seeking,
there is no benefit of using them over the original JarMount (which we
need to preserve for backwards compatibility).

Instead of maintaining two near-identical mounts, we remove the
FileSystemMount and rewrite the JarMount implementation with several
improvements:

 - Rewrite the jar scanning algorithm to be closer to 1.13+'s data pack
   mount. This means we no longer require the jar file to have
   directories before the file (though this was not a problem in
   practice).
 - Add all JarMounts to a ReferenceQueue, closing up the ZipFile when
   they have been garbage collected (fixes #100).
 - Cache the contents of all files for 60 seconds (with some constraints
   on size). This allows us to seek on ROM files too (assuming they are
   small), by reading the whole thing into memory.
   The cache is shared across all mounts, and has a 64MiB limit, and
   thus should not have an adverse impact on memory.

ce0685c31f Move our message model to be closer to Forge's
It's rather embarassing that it's been restructured _again_, but I think
this is a nice middle-ground. The previous implementation was written
mostly for Fabric, which doesn't always map perfectly to Forge.

 - Move the message identifier into the registration phrase. It's not
   really a property of the message itself, rather a property of the
   registry, so better suited there.

 - Move message handling into the message itself. Honestly, it was just
   ending up being rather messy mixing the logic in two places.

   This also means we can drop some proxy methods, as it's easier to
   have conditionally loaded methods.

 - Move network registry into a dedicated class, as that's what we're
   doing for everything else.

932f8a44fc WIP: Http rework (#98)
- Move all HTTP tasks to a unified "MonitoredResource" model. This
   provides a uniform way of tracking object's lifetimes and disposing
   of them when complete.

 - Rewrite HTTP requests to use Netty instead of standard Java. This
   offers several advantages:
    - We have access to more HTTP verbs (mostly PATCH).
    - We can now do http -> https redirects.
    - We no longer need to spawn in a new thread for each HTTP request.
      While we do need to run some tasks off-thread in order to resolve
      IPs, it's generally a much shorter task, and so is less likely to
      inflate the thread pool.

 - Introduce several limits for the http API:
    - There's a limit on how many HTTP requests and websockets may exist
      at the same time. If the limit is reached, additional ones will be
      queued up until pending requests have finished.
    - HTTP requests may upload a maximum of 4Mib and download a maximum
      of 16Mib (configurable).

 - .getResponseCode now returns the status text, as well as the status
   code.

I don't think anyone has actually ended up using this, so it's unlikely
to break anything (though do tell me if this is the case). On the flip
side, this allows us to queue events on multiple computers, and means
we can provide a little more documentation.

776a786e1b Fix InventoryUtil ignoring the stack limit when extracting items
Using turtle.suck on an inventory filled with tools would fill the
entire chest with said item, rather than extracting a single item. In
order to avoid that, we clamp the extract limit to the max stack size
when first extracting an item.

This also inlines the makeSlotList logic, which means we can avoid
creating an array for each inventory operation. This probably won't
have any meaninful performance impact (even on large inventories), but
is a nice optimisation to make.

Some mods (*cough* Computronics *cough*) directly access this class,

62cf921cc6 Allow modems to handle being attached to multiple computers
- Introduce a ModemState, which shares the open channels across all
   modem instances of a wired modem.
 - Keep a set of computers for all modem peripherals.
 - Keep a map of computers -> (string, peripheral) for wired modem
   peripherals. We shouldn't need this one, as you cannot attach one
   modem to another, but it's good to be consistent.

One major change here is that modems will continue to be "on", even if
no computers are attached. This would substantially increase
implementation complexity, so I think this is an acceptable compromise
for now.

redundant. We're keeping the LuaJ sources for now, as I don't really

e7c19bcf55 Change speakers to use the SPacketCustomSound packet instead
The method to register new SoundEvents is private, which means that few
(if any) mods actually register them. Consequently, one could not use
the speaker to play any modded sound, as they weren't registered on the
server side.

Using SPacketCustomSound does mean we can no longer determine if a sound
exists or not, but I think a price I'm willing to pay in order to allow
playing modded sounds.

518eefbe10 Rewrite file systems to use ByteChannels
This replaces the existing IMount openFor* method with openChannelFor*
ones, which return an appropriate byte channel instead.

As channels are not correctly closed when GCed, we introduce a
FileSystemWrapper. We store a weak reference to this, and when it is
GCed or the file closed, we will remove it from our "open file" set and
ensure any underlying buffers are closed.

While this change may seem a little odd, it does introduce some
benefits:

 - We can replace JarMount with a more general FileSystemMount. This
   does assume a read-only file system, but could technically be used
   for other sources.

 - Add support for seekable (binary) handles. We can now look for
   instances of SeekableByteChannel and dynamically add it. This works
   for all binary filesystem and HTTP streams.

 - Rewrite the io library to more accurately emulate PUC Lua's
   implementation. We do not correctly implement some elements (most
   noticably "*n", but it's a definite improvement.

A lot of these don't actually have any effect as they'll only be called

- Make window.reposition's argument validation a little more strict.
   Previously it would accept `window.reposition(x, y, width)` (no
   height argument), just not act upon it.
 - Use select instead of table.unpack within `pastebin run`.
 - Use `parallel.waitForAny` instead of `waitForAll` within the dance
   program.
 - Pipe the entire help file into `textutils.pagedPrint`, rather than
   doing it line by line.
 - Remove bytecode loading disabling from bios.lua. This never worked
   correctly, and serves little purpose as LuaJ is not vulnerable to
   such exploits.

# ![CC: Tweaked](logo.png)
[![Build Status](https://travis-ci.org/SquidDev-CC/CC-Tweaked.svg?branch=master)](https://travis-ci.org/SquidDev-CC/CC-Tweaked)
<img src="logo.png" alt="CC: Restitched" width="100%"/>
CC: Tweaked is a fork of ComputerCraft which aims to provide earlier access to the more experimental and in-development
features of the mod. For a more stable experience, I recommend checking out the
[original mod](https://github.com/dan200/ComputerCraft).

[![Gitpod ready-to-code](https://img.shields.io/badge/Gitpod-ready--to--code-908a85?logo=gitpod)](https://gitpod.io/#https://github.com/Merith-TK/cc-restitched)
## What?
CC: Tweaked (or CC:T for short) does not aim to create a competing fork of ComputerCraft, nor am I planning to take it
in in a vastly different direction to the original mod. In fact, CC:T aims to be a nurturing ground for various
features, with a pull request against the original mod being the end goal.
# CC:R Version VS CC:T Version
CC:R Strives to maintain perfect pairity with CC:T, however in some cases this is not possible, so CC:R might have a "newer" version than what CC:T has, these newer versions will be primarily bugfixes and the like because fabric is "weird" when porting a forge mod
CC:T also includes many pull requests from the community which have not yet been merged, offering a large number
of additional bug fixes and features over the original mod.
## What is CC: Restiched
This is an fork of [Zundrel/cc-tweaked-fabric](https://github.com/Zundrel/cc-tweaked-fabric) who's goal was to port [SquidDev-CC/CC-Tweaked](https://github.com/SquidDev-CC/CC-Tweaked) to the [Fabric](https://fabricmc.net/) modloader. I picked up maintaining the mod because the team working on Zundrel's fork, admitted they had gotten lethargic so I picked it up to make it equal with CC:T
## Features
CC: Tweaked contains the all features of the latest alpha, as well as numerous fixes, performance improvements and
several additional features. I'd recommend checking out [the releases page](https://github.com/SquidDev-CC/CC-Tweaked/releases)
to see the full changes, but here's a couple of the more interesting changes:
## Resource Packs
This mod includes textures that are more in-line with the style of Mojang's new texture-artist, Jappa. If you prefer the original textures, enable the "Classic" resource pack provided by the mod.
- Replace LuaJ with Cobalt.
- Allow running multiple computers at the same time.
- Websocket support in the HTTP library.
- Wired modems and cables act more like multiparts.
- Add map-like rendering for pocket computers and printed pages/books.
- Adds the `/computercraft` command, offering various diagnostic tools for server owners. This allows operators to
track which computers are hogging resources, turn on and shutdown multiple computers at once and interact with
computers remotely.
- Add full-block wired modems, allowing one to wrap non-solid peripherals (such as turtles, or chests if Plethora is
installed).
## Relation to CCTweaks?
This mod has nothing to do with CCTweaks, though there is no denying the name is a throwback to it. That being said,
several features have been included, such as full block modems, the Cobalt runtime and map-like rendering for pocket
computers.
<img src="https://raw.githubusercontent.com/3prm3/cc-pack/main/pack.png" alt="CC: Restitched" width="16" height="16"/> [3prm3/cc-pack](https://github.com/3prm3/cc-pack/)
We also have a second resourcepack made by [3prm3](https://github.com/3prm3), it features a complete overhaul and can be enabled by enabling the `overhaul` resource pack, go check out his resource pack over here!
# Conflicts
Currently Iris and Canvas Shaders are Incompatible with this mod,
- Iris has transparent monitors, and when a computer displays something on the monitor, the face becomes black
- Canvas... uhm
- Computer Terminals are 100% unusable and scuffed
- <img src="https://user-images.githubusercontent.com/16393543/120464345-ab619b00-c351-11eb-9dfb-e68ddc93de5e.png">
- Monitors break with either rendering option
- TBO
- Just crashes on world load
- VBO
- <img src="https://user-images.githubusercontent.com/16393543/120475933-d999a780-c35e-11eb-9d94-ef4e5988ad5f.png">
## Contributing
Any contribution is welcome, be that using the mod, reporting bugs or contributing code. If you do wish to contribute
code, do consider submitting it to the ComputerCraft repository instead.
Any contribution is welcome, be that using the mod, reporting bugs or contributing code. In order to start helping develop CC:R there are a few rules
1) Any updates that port commits from CC:T, ***MUST*** follow the format defined in [patchwork.md](patchwork.md) otherwise they will not be accepted,
* Commit Message must be the same as it is in CC:T,
* patchwork.md must be updated in the following format
> Comments, optional but useful if you had to do something differently than in CC:T outside of [Fabric](https://fabricmc.net/)/[Forge](https://mcforge.readthedocs.io/en/1.16.x/) differences
>
> \`\`\`
>
>commitID
>
> commit title
>
> commit desc
>
> \`\`\`
2) Follow the [Fabric](https://fabricmc.net/) programming guidelines as close as possible. This means you have to use [`loom`](https://fabricmc.net/wiki/tutorial:mappings) mappings,
3) You cannot intentionally implement bugs and security vulnerabilities
4) Unless the commit is a ["patchwork"](https://github.com/Merith-TK/cc-restitched/blob/fabric/patchwork.md) compliant commit, (IE: taken from CC:T), the lua code is off limits
## Bleeding Edge Builds
Bleeding edge builds can be found [here](https://github.com/Merith-TK/cc-restitched/actions) at Github Actions.
That being said, in order to start helping develop CC:T, you'll need to follow these steps:
## Community
If you need help getting started with CC: Tweaked, want to show off your latest project, or just want to chat about ComputerCraft, here is the [Forum](https://forums.computercraft.cc/) and the [Discord](https://discord.gg/H2UyJXe)
- **Clone the repository:** `git clone https://github.com/SquidDev-CC/CC-Tweaked.git && cd CC-Tweaked`
- **Setup Forge:** `./gradlew setupDecompWorkspace`
- **Test your changes:** `./gradlew runClient` (or run the `GradleStart` class from your IDE).
## Known Issues
Main Known issue
* Mods that add blocks that can be used as peripherals for CC:T On forge, don't work with CC:R.
* This is because of the differences between forge and fabric, and that mod devs, to my knowledge have not agreed upon a standard method in which to implement cross compatibility between mods,
* [Fixed (d10f297c): please report if bug persists]</br> ~~Storage Peripherals throw a java "StackOverflowError" when using `pushItems()`,~~
* ~~Work around, you are probably using `pushItems(chest, 1)` or similar. please use `pushItems(chest, 1, nil, 1)`.~~
* Computers will not run built in commands, saying "File not found"
* This is a know bug, dont know what causes it, but just restart the computer (`ctrl+r` for one second) and it will work again
* Occurs when server runs `/reload` or a datapack is updated
If you want to run CC:T in a normal Minecraft instance, run `./gradlew build` and copy the `.jar` from `build/libs`.
## Perpherals
Unfortunately, unlike the original CC:Tweaked project, CC:Restitched, does not have any actual peripheral mods, currently the only one we have is an example for mod devs to get started with making/adding the peripheral API to their mods!
If your a mod dev made a mod with CC:R peripheral support, OR if your a player who found a mod with CC:R support, please open an [issue here](https://github.com/Merith-TK/cc-restitched/issues/new?assignees=&labels=peripheralShoutout&template=peripheral_shoutout.md) to let us know so we can add it to the list!
* ![icon](https://raw.githubusercontent.com/Toad-Dev/cc-peripheral-test/master/src/main/resources/assets/cc_test/textures/block/test_peripheral.png) [CC Peripheral Test](https://github.com/Toad-Dev/cc-peripheral-test)
* This is an example mod for how to make peripherals that work as a block, or as a turtle upgrade!

<h1>1 - <a name="1">Introduction</a></h1>
<h2>Goals of Luaj</h2>
Luaj is a lua interpreter based on the 5.1.x version of lua with the following goals in mind:
<ul>
<li>Java-centric implementation of lua vm built to leverage standard Java features.
<li>Lightweight, high performance execution of lua.
<li>Multi-platform to be able to run on JME, JSE, or JEE environments.
<li>Complete set of libraries and tools for integration into real-world projects.
<li>Dependable due to sufficient unit testing of vm and library features.
</ul>
<h2>Differences with 1.0</h2>
In addition to the basic goals of luaj, version 2.0 is aimed
at improving on the 1.0 vm in the following aspects.
<ul>
<li>Support for compiling lua source code into Java source code.
<li>Support for compiling lua bytecode directly into Java bytecode.
<li>Improved performance of of lua bytecode processing.
<li>Stackless vm design centered around dynamically typed objects.
<li>More alignment with C API (see <a href="names.csv">names.csv</a> for details)
<li>Improved class and package naming conventions.
<li>Improved unit tests of core classes.
<li>Improved quality due to major redesign and rewrite of core elements.
<li>More complete implementation including weak keys and values, and all metatags.
</ul>
<h2>Performance</h2>
Good performance is a major goal of luaj.
The following table provides measured execution times on a subset of benchmarks from
<a href="http://shootout.alioth.debian.org/">the computer language benchmarks game</a>
in comparison with the standard C distribution.

Luaj in interpreted mode performs well for the benchmarks, and even better when source-to-source (lua2java)
or bytecode-to-bytecode (luajc) compilers are used,
and actually executes <em>faster</em> than C-based lua in some cases.
It is also faster than Java-lua implementations Jill, Kahlua, and Mochalua for all benchmarks tested.
<h1>2 - <a name="2">Simple Examples</a></h1>
<h2>Run a lua script in Java SE</h2>
<p>
From the main distribution directory line type:
<pre>
java -cp lib/luaj-jse-2.0.3.jar lua examples/lua/hello.lua
</pre>
<p>
You should see the following output:
<pre>
hello, world
</pre>
To see how luaj can be used to acccess most Java API's including swing, try:
<pre>
java -cp lib/luaj-jse-2.0.3.jar lua examples/lua/swingapp.lua
</pre>
<h2>Compile lua source to lua bytecode</h2>
<p>
From the main distribution directory line type:
<pre>
java -cp lib/luaj-jse-2.0.3.jar luac examples/lua/hello.lua
java -cp lib/luaj-jse-2.0.3.jar lua luac.out
</pre>
<p>
The compiled output "luac.out" is lua bytecode and should run and produce the same result.
<h2>Compile lua source to java source</h2>
<p>
Luaj can compile to lua source code to Java source code:
<pre>
java -cp lib/luaj-jse-2.0.3.jar lua2java -s examples/lua -d . hello.lua
javac -cp lib/luaj-jse-2.0.3.jar hello.java
java -cp &quot;lib/luaj-jse-2.0.3.jar;.&quot; lua -l hello
</pre>
<p>
The output <em>hello.java</em> is Java source, that implements the logic in hello.lua directly.
Once <em>hello.java</em> is compiled into <em>hello.class</em> it can be required and used in place of the original lua script, but with better performance.
There are no additional dependencies for compiling or running source-to-source compiled lua.
<p>
Lua scripts can also be run directly in this mode without precompiling using the <em>lua</em> command with the <b><em>-j</em></b> option when run in JDK 1.5 or higher:
<pre>
java -cp lib/luaj-jse-2.0.3.jar lua -j examples/lua/hello.lua
</pre>
<h2>Compile lua bytecode to java bytecode</h2>
<p>
Luaj can compile lua sources or binaries directly to java bytecode if the bcel library is on the class path. From the main distribution directory line type:
<pre>
ant bcel-lib
java -cp &quot;lib/luaj-jse-2.0.3.jar;lib/bcel-5.2.jar&quot; luajc -s examples/lua -d . hello.lua
java -cp &quot;lib/luaj-jse-2.0.3.jar;.&quot; lua -l hello
</pre>
<p>
The output <em>hello.class</em> is Java bytecode, should run and produce the same result.
There is no runtime dependency on the bcel library,
but the compiled classes must be in the class path at runtime, unless runtime jit-compiling via luajc and bcel are desired (see later sections).
<p>
Lua scripts can also be run directly in this mode without precompiling using the <em>lua</em> command with the <b><em>-b</em></b> option and providing the <em>bcel</em> library in the class path:
<pre>
java -cp &quot;lib/luaj-jse-2.0.3.jar;lib/bcel-5.2.jar&quot; lua -b examples/lua/hello.lua
</pre>
<h2>Run a script in a Java Application</h2>
<p>
The following pattern is used within Java SE
<pre>
import org.luaj.vm2.*;
import org.luaj.vm2.lib.jse.*;
String script = "examples/lua/hello.lua";
LuaValue _G = JsePlatform.standardGlobals();
_G.get("dofile").call( LuaValue.valueOf(script) );
</pre>
<p>
A simple example may be found in
<pre>
examples/jse/SampleJseMain.java
</pre>
<p>
You must include the library <b>lib/luaj-jse-2.0.3.jar</b> in your class path.
<h2>Run a script in a MIDlet</h2>
<p>
The for MIDlets the <em>JmePlatform</em> is used instead:
<pre>
import org.luaj.vm2.*;
import org.luaj.vm2.lib.jme.*;
String script = "examples/lua/hello.lua";
LuaValue _G = JmePlatform.standardGlobals();
_G.get("dofile").call( LuaValue.valueOf(script) );
</pre>
<p>
The file must be a resource within within the midlet jar for <em>dofile()</em> to find it.
Any files included via <em>require()</em> must also be part of the midlet resources.
<p>
A simple example may be found in
<pre>
examples/jme/SampleMIDlet.java
</pre>
<p>
You must include the library <b>lib/luaj-jme-2.0.3.jar</b> in your midlet jar.
<p>
An ant script to build and run the midlet is in
<pre>
build-midlet.xml
</pre>
<p>
You must install the wireless toolkit and define <em>WTK_HOME</em> for this script to work.
<h2>Run a script using JSR-223 Dynamic Scripting</h2>
<p>
The standard use of JSR-223 scripting engines may be used:
<pre>
ScriptEngineManager mgr = new ScriptEngineManager();
ScriptEngine e = mgr.getEngineByExtension(".lua");
e.put("x", 25);
e.eval("y = math.sqrt(x)");
System.out.println( "y="+e.get("y") );
</pre>
<p>
All standard aspects of script engines including compiled statements should be supported.
<p>
You must include the library <b>lib/luaj-jse-2.0.3.jar</b> in your class path.
<p>
A working example may be found in
<pre>
examples/jse/ScriptEngineSample.java
</pre>
To compile and run it using Java 1.6 or higher:
<pre>
javac examples/jse/ScriptEngineSample.java
java -cp &quot;lib/luaj-jse-2.0.3.jar;examples/jse&quot; ScriptEngineSample
</pre>
<h2>Excluding the lua bytecode compiler</h2>
By default, the compiler is included whenever <em>standardGlobals()</em> or <em>debugGlobals()</em> are called.
Without a compiler, files can still be executed, but they must be compiled elsewhere beforehand.
The "luac" utility is provided in the jse jar for this purpose, or a standard lua compiler can be used.
<p>
To exclude the lua-to-lua-bytecode compiler, do not call
<em>standardGlobals()</em> or <em>debugGlobals()</em>
but instead initialize globals with including only those libraries
that are needed and omitting the line:
<pre>
org.luaj.vm2.compiler.LuaC.install();
</pre>
<h2>Including the Lua2Java lua-source-to-Java-source compiler</h2>
<p>
To compile from lua sources to Java sources for all lua loaded at runtime,
install the Lua2Java compiler <em>after</em> globals have been created using:
<pre>
org.luaj.vm2.jse.lua2java.Lua2Java.install();
</pre>
This uses the system Java compiler to compile from Java source to Java bytecode,
and cannot compile lua binary files containing lua bytecode at runtime.
<h2>Including the LuaJC lua-bytecode-to-Java-bytecode compiler</h2>
<p>
To compile from lua to Java bytecode for all lua loaded at runtime,
install the LuaJC compiler <em>after</em> globals have been created using:
<pre>
org.luaj.vm2.jse.luajc.LuaJC.install();
</pre>
<p>
This will compile all lua bytecode into Java bytecode, regardless of if they are loaded as
lua source or lua binary files.
<p>
The requires <em>bcel</em> to be on the class path, and the ClassLoader of JSE or CDC.
<h1>3 - <a name="3">Concepts</a></h1>
<h2>Globals</h2>
The old notion of platform has been replaced with creation of globals.
Two classes are provided to encapsulate common combinations of libraries.
<h3>JsePlatform</h3>
This class can be used as a factory for globals in a typical Java SE application.
All standard libraries are included, as well as the luajava library.
The default search path is the current directory,
and the math operations include all those supported by Java SE.
<h3>JmePlatform</h3>
This class can be used to set up the basic environment for a Java ME application.
The default search path is limited to the jar resources,
and the math operations are limited to those supported by Java ME.
All libraries are included except luajava, and the os, io, and math libraries are
limited to those functions that can be supported on that platform.
<h1>4 - <a name="4">Libraries</a></h1>
<h2>Standard Libraries</h2>
Libraries are coded to closely match the behavior specified in
See <a href="http://www.lua.org/manual/5.1/">standard lua documentation</a> for details on the library API's
<p>
The following libraries are loaded by both <em>JsePlatform.standardGlobals()</em> and <em>JmePlatform.standardGlobals()</em>:
<pre> base
coroutine
io
math
os
package
string
table
</pre>
<p>
The <em>JsePlatform.standardGlobals()</em> globals also include:
<pre> luajava
</pre>
<p>
The <em>JsePlatform.debugGlobals()</em> and <em>JsePlatform.debugGlobals()</em> functions produce globals that include:
<pre> debug
</pre>
<h3>I/O Library</h3>
The implementation of the <em>io</em> library differs by platform owing to platform limitations.
<p>
The <em>JmePlatform.standardGlobals()</em> instantiated the io library <em>io</em> in
<pre>
src/jme/org/luaj/vm2/lib/jme/JmeIoLib.java
</pre>
The <em>JsePlatform.standardGlobals()</em> includes support for random access and is in
<pre>
src/jse/org/luaj/vm2/lib/jse/JseIoLib.java
</pre>
<h3>OS Library</h3>
The implementation of the <em>os</em> library also differs per platform.
<p>
The basic <em>os</em> library implementation us used by <em>JmePlatform</em> and is in:
<pre>
src/core/org/luaj/lib/OsLib.java
</pre>
A richer version for use by <em>JsePlatform</em> is :
<pre>
src/jse/org/luaj/vm2/lib/jse/JseOsLib.java
</pre>
Time is a represented as number of milliseconds since the epoch,
and most time and date formatting, locales, and other features
are not implemented.
<h3>Coroutine Library</h3>
The <em>coroutine</em> library is implemented using one JavaThread per coroutine.
This allows <em>coroutine.yield()</em> can be called from anywhere,
as with the yield-from-anywhere patch in C-based lua.
<p>
Luaj uses WeakReferences and the OrphanedThread error to ensure that coroutines that are no longer referenced
are properly garbage collected. For thread safety, OrphanedThread should not be caught by Java code.
See <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/LuaThread.html">LuaThread</a>
and <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/OrphanedThread.html">OrphanedThread</a>
javadoc for details.
<h3>Debug Library</h3>
The <em>debug</em> library is not included by default by
<em>JmePlatform.standardGlobals()</em> or <em>JsePlatform.standardGlobsls()</em> .
The functions <em>JmePlatform.debugGlobals()</em> and <em>JsePlatform.debugGlobsls()</em>
create globals that contain the debug library in addition to the other standard libraries.
To install dynamically from lua use java-class-based require:</em>:
<pre>
require 'org.luaj.vm2.lib.DebugLib'
</pre>
The <em>lua</em> command line utility includes the <em>debug</em> library by default.
<h3>The Luajava Library</h3>
The <em>JsePlatform.standardGlobals()</em> includes the <em>luajava</em> library, which simplifies binding to Java classes and methods.
It is patterned after the original <a href="http://www.keplerproject.org/luajava/">luajava project</a>.
<p>
The following lua script will open a swing frame on Java SE:
<pre>
jframe = luajava.bindClass( "javax.swing.JFrame" )
frame = luajava.newInstance( "javax.swing.JFrame", "Texts" );
frame:setDefaultCloseOperation(jframe.EXIT_ON_CLOSE)
frame:setSize(300,400)
frame:setVisible(true)
</pre>
<p>
See a longer sample in <em>examples/lua/swingapp.lua</em> for details, including a simple animation loop, rendering graphics, mouse and key handling, and image loading.
Or try running it using:
<pre>
java -cp lib/luaj-jse-2.0.3.jar lua examples/lua/swingapp.lua
</pre>
<p>
The Java ME platform does not include this library, and it cannot be made to work because of the lack of a reflection API in Java ME.
<p>
The <em>lua</em> connand line tool includes <em>luajava</em>.
<h1>5 - <a name="5">LuaJ API</a></h1>
<h2>API Javadoc</h2>
The javadoc for the main classes in the LuaJ API are on line at
<pre>
<a href="http://luaj.sourceforge.net/api/2.0/index.html">http://luaj.sourceforge.net/api/2.0</a>
</pre>
You can also build a local version from sources using
<pre>
ant doc
</pre>
<h2>LuaValue and Varargs</h2>
All lua value manipulation is now organized around
<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/LuaValue.html">LuaValue</a>
which exposes the majority of interfaces used for lua computation.
<pre>
<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/LuaValue.html">org.luaj.vm2.LuaValue</a>
</pre>
<h3>Common Functions</h3>
<em>LuaValue</em> exposes functions for each of the operations in LuaJ.
Some commonly used functions and constants include:
<pre>
call(); // invoke the function with no arguments
call(LuaValue arg1); // call the function with 1 argument
invoke(Varargs arg); // call the function with variable arguments, variable return values
get(int index); // get a table entry using an integer key
get(LuaValue key); // get a table entry using an arbitrary key, may be a LuaInteger
rawget(int index); // raw get without metatable calls
valueOf(int i); // return LuaValue corresponding to an integer
valueOf(String s); // return LuaValue corresponding to a String
toint(); // return value as a Java int
tojstring(); // return value as a Java String
isnil(); // is the value nil
NIL; // the value nil
NONE; // a Varargs instance with no values
</pre>
<h2>Varargs</h2>
The interface <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/Varargs.html">Varargs</a> provides an abstraction for
both a variable argument list and multiple return values.
For convenience, <em>LuaValue</em> implements <em>Varargs</em> so a single value can be supplied anywhere
variable arguments are expected.
<pre>
<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/Varargs.html">org.luaj.vm2.Varargs</a>
</pre>
<h3>Common Functions</h3>
<em>Varargs</em> exposes functions for accessing elements, and coercing them to specific types:
<pre>
narg(); // return number of arguments
arg1(); // return the first argument
arg(int n); // return the nth argument
isnil(int n); // true if the nth argument is nil
checktable(int n); // return table or throw error
optlong(int n,long d); // return n if a long, d if no argument, or error if not a long
</pre>
See the <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/Varargs.html">Varargs</a> API for a complete list.
<h2>LibFunction</h2>
The simplest way to implement a function is to choose a base class based on the number of arguments to the function.
LuaJ provides 5 base classes for this purpose, depending if the function has 0, 1, 2, 3 or variable arguments,
and if it provide multiple return values.
<pre>
<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/ZeroArgFunction.html">org.luaj.vm2.lib.ZeroArgFunction</a>
<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/OneArgFunction.html">org.luaj.vm2.lib.OneArgFunction</a>
<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/TwoArgFunction.html">org.luaj.vm2.lib.TwoArgFunction</a>
<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/ThreeArgFunction.html">org.luaj.vm2.lib.ThreeArgFunction</a>
<a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/lib/VarArgFunction.html">org.luaj.vm2.lib.VarArgFunction</a>
</pre>
Each of these functions has an abstract method that must be implemented,
and argument fixup is done automatically by the classes as each Java function is invoked.
<p>
For example, to implement a &quot;hello, world&quot; function, we could supply:
<pre>
pubic class hello extends ZeroArgFunction {
public LuaValue call() {
env.get("print").call(valueOf("hello, world"));
}
}
</pre>
The value <em>env</em> is the environment of the function, and is normally supplied
by the instantiating object whenever default loading is used.
<p>
Calling this function from lua could be done by:
<pre>
require( 'hello' )()
</pre>
while calling this function from Java would look like:
<pre>
new hello().call();
</pre>
Note that in both the lua and Java case, extra arguments will be ignored, and the function will be called.
Also, no virtual machine instance is necessary to call the function.
To allow for arguments, or return multiple values, extend one of the other base classes.
<h2>Closures</h2>
Closures still exist in this framework, but are optional, and are only used to implement lua bytecode execution.
<h1>6 - <a name="6">Parser</a></h1>
<h2>Javacc Grammar</h2>
A Javacc grammarwas developed to simplify the creation of Java-based parsers for the lua language.
The grammar is specified for <a href="https://javacc.dev.java.net/">javacc version 5.0</a> because that tool generates standalone
parsers that do not require a separate runtime.
<p>
A plain undecorated grammer that can be used for validation is available in <a href="grammar/Lua51.jj">grammar/Lua51.jj</a>
while a grammar that generates a typed parse tree is in <a href="grammar/LuaParser.jj">grammar/LuaParser.jj</a>
<h2>Creating a Parse Tree from Lua Source</h2>
The default lu compiler does a single-pass compile of lua source to lua bytecode, so no explicit parse tree is produced.
<p>
To simplify the creation of abstract syntax trees from lua sources, the LuaParser class is generated as part of the JME build.
To use it, provide an input stream, and invoke the root generator, which will return a Chunk if the file is valid,
or throw a ParseException if there is a syntax error.
<p>
For example, to parse a file and print all variable names, use code like:
<pre>
try {
String file = "main.lua";
LuaParser parser = new LuaParser(new FileInputStream(file));
Chunk chunk = parser.Chunk();
chunk.accept( new Visitor() {
public void visit(Exp.NameExp exp) {
System.out.println("Name in use: "+exp.name.name);
}
} );
} catch ( ParseException e ) {
System.out.println("parse failed: " + e.getMessage() + "\n"
+ "Token Image: '" + e.currentToken.image + "'\n"
+ "Location: " + e.currentToken.beginLine + ":" + e.currentToken.beginColumn
+ "-" + e.currentToken.endLine + "," + e.currentToken.endColumn);
}
</pre>
In luaj 2.0.3 error reporting was turned on in the parser so line numbers are avaiable for most parse exceptions.
This example may be found in
<pre>
examples/jse/SampleParser.java
</pre>
<p>
See the <a href="http://luaj.sourceforge.net/api/2.0/org/luaj/vm2/ast/package-summary.html">org.luaj.vm2.ast package</a> javadoc for the API relating to the syntax tree that is produced.
<h1>7 - <a name="7">Building and Testing</a></h1>
<h2>Building the jars</h2>
An ant file is included in the root directory which builds the libraries by default.
<p>
Other targets exist for creating distribution file an measuring code coverage of unit tests.
<h2>Unit tests</h2>
<p>
The main luaj JUnit tests are organized into a JUnit 3 suite:
<pre>
test/junit/org/luaj/vm2/AllTests.lua
</pre>
<p>
Unit test scripts can be found in these locations
<pre>
test/lua/*.lua
test/junit/org/luaj/vm2/compiler/lua5.1-tests.zip
test/junit/org/luaj/vm2/compiler/regressions.zip
test/junit/org/luaj/vm2/vm1/luajvm1-tests.zip
</pre>
<h2>Code coverage</h2>
<p>
A build script for running unit tests and producing code coverage statistics is in
<pre>
build-coverage.xml
</pre>
It relies on the cobertura code coverage library.

Notes:
(*) In OP_CALL, if (B == 0) then B = top. C is the number of returns - 1,
and can be 0: OP_CALL then sets `top' to last_result+1, so
next open instruction (OP_CALL, OP_RETURN, OP_SETLIST) may use `top'.
(*) In OP_VARARG, if (B == 0) then use actual number of varargs and
set top (like in OP_CALL with C == 0).
(*) In OP_RETURN, if (B == 0) then return up to `top'
(*) In OP_SETLIST, if (B == 0) then B = `top';
if (C == 0) then next `instruction' is real C
(*) For comparisons, A specifies what condition the test should accept
(true or false).
(*) All `skips' (pc++) assume that next instruction is a jump

/**
* Extension of {@link LuaFunction} which executes lua bytecode.
* <p>
* A {@link LuaClosure} is a combination of a {@link Prototype}
* and a {@link LuaValue} to use as an environment for execution.
* <p>
* There are three main ways {@link LuaClosure} instances are created:
* <ul>
* <li>Construct an instance using {@link #LuaClosure(Prototype, LuaValue)}</li>
* <li>Construct it indirectly by loading a chunk via {@link LuaCompiler#load(java.io.InputStream, String, LuaValue)}
* <li>Execute the lua bytecode {@link Lua#OP_CLOSURE} as part of bytecode processing
* </ul>
* <p>
* To construct it directly, the {@link Prototype} is typically created via a compiler such as {@link LuaC}:
* <pre> {@code
* InputStream is = new ByteArrayInputStream("print('hello,world').getBytes());
* Prototype p = LuaC.instance.compile(is, "script");
* LuaValue _G = JsePlatform.standardGlobals()
* LuaClosure f = new LuaClosure(p, _G);
* }</pre>
* <p>
* To construct it indirectly, the {@link LuaC} compiler may be used,
* which implements the {@link LuaCompiler} interface:
* <pre> {@code
* LuaFunction f = LuaC.instance.load(is, "script", _G);
* }</pre>
* <p>
* Typically, a closure that has just been loaded needs to be initialized by executing it,
* and its return value can be saved if needed:
* <pre> {@code
* LuaValue r = f.call();
* _G.set( "mypkg", r )
* }</pre>
* <p>
* In the preceding, the loaded value is typed as {@link LuaFunction}
* to allow for the possibility of other compilers such as {@link LuaJC}
* producing {@link LuaFunction} directly without
* creating a {@link Prototype} or {@link LuaClosure}.
* <p>
* Since a {@link LuaClosure} is a {@link LuaFunction} which is a {@link LuaValue},
* all the value operations can be used directly such as:
* <ul>
* <li>{@link LuaValue#setfenv(LuaValue)}</li>
* <li>{@link LuaValue#call()}</li>
* <li>{@link LuaValue#call(LuaValue)}</li>
* <li>{@link LuaValue#invoke()}</li>
* <li>{@link LuaValue#invoke(Varargs)}</li>
* <li>{@link LuaValue#method(String)}</li>
* <li>{@link LuaValue#method(String,LuaValue)}</li>

* <p>
* To instantiate and use it directly,
* link it into your globals table via {@link LuaValue#load(LuaValue)} using code such as:
* <pre> {@code
* LuaTable _G = new LuaTable();
* LuaThread.setGlobals(_G);
* _G.load(new BaseLib());
* _G.get("print").call(LuaValue.valueOf("hello, world"));
* } </pre>
* Doing so will ensure the library is properly initialized
* and loaded into the globals table.
* <p>
* This is a direct port of the corresponding library in C.

/**
* Abstract base class extending {@link LibFunction} which implements the
* core of the lua standard {@code io} library.
* <p>
* It contains the implementation of the io library support that is common to
* the JSE and JME platforms.
* In practice on of the concrete IOLib subclasses is chosen:
* {@link org.luaj.vm2.lib.jse.JseIoLib} for the JSE platform, and
* {@link org.luaj.vm2.lib.jme.JmeIoLib} for the JME platform.
* <p>
* The JSE implementation conforms almost completely to the C-based lua library,
* while the JME implementation follows closely except in the area of random-access files,
* which are difficult to support properly on JME.
* <p>
* Typically, this library is included as part of a call to either
* {@link JsePlatform#standardGlobals()} or {@link JmePlatform#standardGlobals()}
* <p>
* To instantiate and use it directly,
* link it into your globals table via {@link LuaValue#load(LuaValue)} using code such as:
* <pre> {@code
* LuaTable _G = new LuaTable();
* _G.load(new JseIoLib());
* LuaThread.setGlobals(_G);
* _G.load(new JseBaseLib());
* _G.load(new PackageLib());
* _G.load(new JseIoLib());
* _G.get("io").get("write").call(LuaValue.valueOf("hello, world\n"));
* } </pre>
* Doing so will ensure the library is properly initialized
* and loaded into the globals table.
* <p>
* This has been implemented to match as closely as possible the behavior in the corresponding library in C.

/**
* Subclass of {@link LuaFunction} common to Java functions exposed to lua.
* <p>
* To provide for common implementations in JME and JSE,
* library functions are typically grouped on one or more library classes
* and an opcode per library function is defined and used to key the switch
* to the correct function within the library.
* <p>
* Since lua functions can be called with too few or too many arguments,
* and there are overloaded {@link LuaValue#call()} functions with varying
* number of arguments, a Java function exposed in lua needs to handle the
* argument fixup when a function is called with a number of arguments
* differs from that expected.
* <p>
* To simplify the creation of library functions,
* there are 5 direct subclasses to handle common cases based on number of
* argument values and number of return return values.
* <ul>
* <li>{@link ZeroArgFunction}</li>
* <li>{@link OneArgFunction}</li>
* <li>{@link TwoArgFunction}</li>
* <li>{@link ThreeArgFunction}</li>
* <li>{@link VarArgFunction}</li>
* </ul>
* <p>
* To be a Java library that can be loaded via {@code require}, it should have
* a public constructor that returns a {@link LuaValue} that, when executed,
* initializes the library.
* <p>
* For example, the following code will implement a library called "hyperbolic"
* with two functions, "sinh", and "cosh":
<pre> {@code
* import org.luaj.vm2.LuaValue;
* import org.luaj.vm2.lib.OneArgFunction;
*
* public class hyperbolic extends OneArgFunction {
*
* public hyperbolic() {}
*
* public LuaValue call(LuaValue libname) {
* LuaValue library = tableOf();
* library.set( "sinh", new sinh() );
* library.set( "cosh", new cosh() );
* env.set( "hyperbolic", library );
* return library;
* }
*
* static class sinh extends OneArgFunction {
* public LuaValue call(LuaValue x) {
* return LuaValue.valueOf(Math.sinh(x.checkdouble()));
* }
* }
*
* static class cosh extends OneArgFunction {
* public LuaValue call(LuaValue x) {
* return LuaValue.valueOf(Math.cosh(x.checkdouble()));
* }
* }
*}
*}</pre>
* The default constructor is used to instantiate the library
* in response to {@code require 'hyperbolic'} statement,
* provided it is on Javas class path.
* This instance is then invoked with the name supplied to require()
* as the only argument, and library should initialized whatever global
* data it needs to and place it into the environment if needed.
* In this case, it creates two function, 'sinh', and 'cosh', and puts
* them into a global table called 'hyperbolic.'
* It placed the library table into the globals via the {@link #env}
* local variable which corresponds to the globals that apply when the
* library is loaded.

* <p>
* It contains only the math library support that is possible on JME.
* For a more complete implementation based on math functions specific to JSE

* In Particular the following math functions are <b>not</b> implemented by this library:
* <ul>
* <li>acos</li>
* <li>asin</li>

* <li>cosh</li>
* <li>log</li>

* <li>atan2</li>
* </ul>
* <p>
* The implementations of {@code exp()} and {@code pow()} are constructed by
* hand for JME, so will be slower and less accurate than when executed on the JSE platform.
* <p>
* Typically, this library is included as part of a call to either
* {@link JmePlatform#standardGlobals()}
* <p>
* To instantiate and use it directly,
* link it into your globals table via {@link LuaValue#load(LuaValue)} using code such as:
* <pre> {@code
* LuaTable _G = new LuaTable();
* LuaThread.setGlobals(_G);

* _G.load(new MathLib());
* System.out.println( _G.get("math").get("sqrt").call( LuaValue.valueOf(2) ) );

/**
* Subclass of {@link LibFunction} which implements the lua standard package and module
* library functions.
*
* <p>
* Typically, this library is included as part of a call to either
* {@link JsePlatform#standardGlobals()} or {@link JmePlatform#standardGlobals()}
* <p>
* To instantiate and use it directly,
* link it into your globals table via {@link LuaValue#load(LuaValue)} using code such as:
* <pre> {@code
* LuaTable _G = new LuaTable();
* LuaThread.setGlobals(_G);
* _G.load(new BaseLib());
* _G.load(new PackageLib());
* System.out.println( _G.get("require").call(LuaValue.valueOf("hyperbolic")) );
* } </pre>
* In practice, the first 4 lines of the above are minimal requirements to get
* and initialize a globals table capable of basic reqire, print, and other functions,
* so it is much more convenient to use the {@link JsePlatform} and {@link JmePlatform}
* utility classes instead.
* <p>
* This has been implemented to match as closely as possible the behavior in the corresponding library in C.
* However, the default filesystem search semantics are different and delegated to the bas library
* as outlined in the {@link BaseLib} and {@link JseBaseLib} documetnation.

* This function also initializes t._NAME with the given name, t._M with the

* name minus last component; see below). Finally, module sets t as the new
* environment of the current function and the new value of
* package.loaded[name], so that require returns t.
*
* If name is a compound name (that is, one with components separated by
* dots), module creates (or reuses, if they already exist) tables for each
* component. For instance, if name is a.b.c, then module stores the module
* table in field c of field b of global a.

* Loads the given module. The function starts by looking into the package.loaded table to

* stored at package.loaded[modname]. Otherwise, it tries to find a loader for the module.
*
* To find a loader, require is guided by the package.loaders array. By changing this array,
* we can change how require looks for a module. The following explanation is based on the
* default configuration for package.loaders.
*
* First require queries package.preload[modname]. If it has a value, this value
* (which should be a function) is the loader. Otherwise require searches for a Lua loader
* using the path stored in package.path. If that also fails, it searches for a C loader
* using the path stored in package.cpath. If that also fails, it tries an all-in-one loader
* (see package.loaders).
*
* Once a loader is found, require calls the loader with a single argument, modname.
* If the loader returns any value, require assigns the returned value to package.loaded[modname].
* If the loader returns no value and has not assigned any value to package.loaded[modname],
* then require assigns true to this entry. In any case, require returns the final value of
* package.loaded[modname].
*
* If there is any error loading or running the module, or if it cannot find any loader for
* the module, then require signals an error.

/** The {@link JmePlatform} class is a convenience class to standardize
* how globals tables are initialized for the JME platform.
* <p>
* The JME platform, being limited, cannot implement all libraries in all aspects. The main limitations are
* <ul>
* <li>Some math functions are not implemented, see {@link MathLib} for details</li>
* <li>Scripts are loaded via Class.getResourceAsStream(), see {@link BaseLib} for details</li>
* <li>OS functions execute(), remove(), rename(), and tmpname() vary, see {@link OsLib} for details</li>
* <li>I/O seek is not implemented, see {@link JmeIoLib} for details</li>
* <li>luajava is not available, see {@link LuajavaLib} for details</li>
* </ul>
* <p>
* It is used to allocate either a set of standard globals using
* {@link #standardGlobals()} or debug globals using {@link #debugGlobals()}
* <p>
* A simple example of initializing globals and using them from Java is:
* <pre> {@code
* LuaValue _G = JmePlatform.standardGlobals();
* _G.get("print").call(LuaValue.valueOf("hello, world"));
* } </pre>
* <p>
* Once globals are created, a simple way to load and run a script is:
* <pre> {@code
* LoadState.load( getClass().getResourceAsStream("main.lua"), "main.lua", _G ).call();
* } </pre>
* <p>
* although {@code require} could also be used:
* <pre> {@code
* _G.get("require").call(LuaValue.valueOf("main"));
* } </pre>
* For this to succeed, the file "main.lua" must be a resource in the class path.
* See {@link BaseLib} for details on finding scripts using {@link ResourceFinder}.
* <p>
* The standard globals will contain all standard libraries in their JME flavors:
* <ul>
* <li>{@link BaseLib}</li>
* <li>{@link PackageLib}</li>
* <li>{@link TableLib}</li>
* <li>{@link StringLib}</li>
* <li>{@link CoroutineLib}</li>
* <li>{@link MathLib}</li>
* <li>{@link JmeIoLib}</li>
* <li>{@link OsLib}</li>
* </ul>
* In addition, the {@link LuaC} compiler is installed so lua files may be loaded in their source form.
* <p>
* The debug globals are simply the standard globals plus the {@code debug} library {@link DebugLib}.
* <p>
* <p>
* The class ensures that initialization is done in the correct order,
* and that linkage is made to {@link LuaThread#setGlobals(LuaValue)}.
