This allows for configuring the size of computers and pocket computers,
as well as the max size of monitors.
There's several limitations with the current implementation, but it's
still "good enough" for an initial release:
- Turtles cannot be resized.
- GUIs do not scale themselves, so "large" sizes will not render within
the default resolution.
timetout, max_upload, max_download and max_websocket_message may now be
configured on a domain-by-domain basis. This uses the same system that
we use for the block/allow-list from before:
Example:
[[http.rules]]
host = "*"
action = "allow"
max_upload = 4194304
max_download = 16777216
timeout = 30000
When creating a peripheral or custom Lua object, one must implement two
methods:
- getMethodNames(): String[] - Returns the name of the methods
- callMethod(int, ...): Object[] - Invokes the method using an index in
the above array.
This has a couple of problems:
- It's somewhat unwieldy to use - you need to keep track of array
indices, which leads to ugly code.
- Functions which yield (for instance, those which run on the main
thread) are blocking. This means we need to spawn new threads for
each CC-side yield.
We replace this system with a few changes:
- @LuaFunction annotation: One may annotate a public instance method
with this annotation. This then exposes a peripheral/lua object
method.
Furthermore, this method can accept and return a variety of types,
which often makes functions cleaner (e.g. can return an int rather
than an Object[], and specify and int argument rather than
Object[]).
- MethodResult: Instead of returning an Object[] and having blocking
yields, functions return a MethodResult. This either contains an
immediate return, or an instruction to yield with some continuation
to resume with.
MethodResult is then interpreted by the Lua runtime (i.e. Cobalt),
rather than our weird bodgey hacks before. This means we no longer
spawn new threads when yielding within CC.
- Methods accept IArguments instead of a raw Object array. This has a
few benefits:
- Consistent argument handling - people no longer need to use
ArgumentHelper (as it doesn't exist!), or even be aware of its
existence - you're rather forced into using it.
- More efficient code in some cases. We provide a Cobalt-specific
implementation of IArguments, which avoids the boxing/unboxing when
handling numbers and binary strings.
This is sufficiently useful a class, that it's worthwhile exposing it.
Hopefully we can slowly encourage other mods to migrate to it (well, at
least in 1.14), and so make error messages more consistent.
Also:
- Add Javadoc for all public methods
- Clarify the method names a little (getNumber -> getDouble,
getReal -> getFiniteDouble).
- Make the *Table methods return a Map<?,?> instead of
Map<Object, Object>.
Lua 5.2+ uses loadfile(filename, mode, env), not loadfile(filename,
env). While this is a minor incompatibility, it'd be nice to be
consistent as much as possible.
We try to handle the incorrect case too, as obviously we don't want to
break existing programs.
- Adds a CheckStyle configuration which is pretty similar to CC's
existing one.
- Add the Gradle license plugin.
- Ensure the existing source code is compatible with these additional
checks.
See #239
- 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)).
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.
This runs tests on CraftOS using a tiny test runner that I originally
knocked up for LuaDash. It can be run both from JUnit (so IDEA and
Gradle) and in-game in the shell, so is pretty accessible to work with.
I also add a very basic POC test for the io library. I'd like to flesh
this out soon enough to contain most of the things from the original io
test.
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.
Oh goodness, when will it end?
- Computer errors are shown in red.
- Lua machine operations provide whether they succeeded, and an
optional error message (reason bios failed to load, timeout error,
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.
Errors within the Lua machine are displayed in a more friendly
- Move state management (turnOn, shutdown, etc...) event handling and
the command queue into a ComputerExecutor
- This means the computer thread now just handles running "work" on
computer executors, rather than managing a separate command queue +
requeuing it.
Ideally we'd add a couple more tests in the future, but this'll do for
now.
The bootstrap class is largely yoinked from CCTweaks-Lua, so is a tad
ugly. It works though.
