- Move TaskCallback into the API and make it package private. This
effectively means it's not an API class, just exists there for
convenience reasons.
- Replace any usage of TaskCallback.make with
ILuaContext.executeMainThreadTask.
- Some minor formatting/checkstyle changes to bring us inline with
IntelliJ config.
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.
Oh goodness, this is going to painful to update to 1.13.
We now translate:
- Computer/Disk ID tooltips
- /computercraft descriptions, synopsises and usages. The last of these
may not always be translated when in SMP, as it is sometimes done on
the server, but the alternative would be more complex than I'm happy
with.
- Tracking field names. Might be worth adding descriptions too in the
future.
Also cleanup a couple of other translation keys, so they're more
consistent with Minecraft.
Closes#141
- Share the ILuaContext across all method calls, as well as shifting it
into an anonymous class.
- Move the load/loadstring prefixing into bios.lua
- Be less militant in prefixing chunk names:
- load will no longer do any auto-prefixing.
- loadstring will not prefix when there no chunk name is supplied.
Before we would do `"=" .. supplied_program`, which made no sense.
