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.
- cc.pretty.pretty now accepts two additional options:
- function_args: Show function arguments
- function_source: Show where functions are defined.
- Expose the two options as lua.* settings (defaulting function_args to
true, and function_source to false).
These are then used in the Lua REPL.
Closes#361
- Use jacoco for Java-side coverage. Our Java coverage is /terrible
(~10%), as we only really test the core libraries. Still a good thing
to track for regressions though.
- mcfly now tracks Lua side coverage. This works in several stages:
- Replace loadfile to include the whole path
- Add a debug hook which just tracks filename->(lines->count). This
is then submitted to the Java test runner.
- On test completion, we emit a luacov.report.out file.
As the debug hook is inserted by mcfly, this does not include any
computer startup (such as loading apis, or the root of bios.lua),
despite they're executed.
This would be possible to do (for instance, inject a custom header
into bios.lua). However, we're not actually testing any of the
behaviour of startup (aside from "does it not crash"), so I'm not
sure whether to include it or not. Something I'll most likely
re-evaluate.
This functions the same as shell.run, but does not tokenise the
arguments. This allows us to pass command line arguments through to
another program without having to re-quote them.
Closes#417
- The store is now split into two sections:
- A list of possible options, with some metadata about them.
- A list of values which have been changed.
- settings.define can be used to register a new option. We have
migrated all existing options over to use it. This can be used to
define a default value, description, and a type the setting must have
(such as `string` or `boolean).
- settings.{set,unset,clear,load,store} operate using this value list.
This means that only values which have been changed are stored to
disk.
Furthermore, clearing/unsetting will reset to the /default/ value,
rather than removing entirely.
- The set program will now display descriptions.
- settings.{load,save} now default to `.settings` if no path is given.
This is relatively unoptimised right now, but should be efficient enough
for most practical applications.
- Add textutils.json_null. This will be serialized into a literal
`null`. When deserializing, and parse_null is true, this will be
returned instead of a nil.
- Add textutils.unserializeJSON (and textutils.unserializeJSON). This
is a standard compliant JSON parser (hopefully).
- Passing in nbt_style to textutils.unserializeJSON will handle
stringified NBT (no quotes around object keys, numeric suffices). We
don't currently support byte/long/int arrays - something to add in
a future commit.
- Remove stub for table.pack/table.unpack.
- Remove Lua 5.3 bitlib stub. We're not on 5.3, there's no
point emulating it.
- Change peripheral.call to correctly adjust the error level. This is a
terrible hack, but I believe the only good option.
It'd be good to remove load as well, but it's a little more complex due
to our injecting of _ENV.
Closes#363
- Return EPOCH if a zip entry's creation/modification/access time is
missing.
- If a BasicFileAttributes.*Time method returns null, use 0 as our
time. This shouldn't happen, but is a good sanity check.
Fixes#371
This adds documentation comments to many of CC's Lua APIs, and
a couple of the Java ones, through the use of stubs. We then
export these to HTML using illuaminate [1] and upload them to our
documentation site [2].
Uploads currently occur on pushes to master and any release/tag. The
site is entirely static - there is no way to switch between versions,
etc... but hopefully we can improve this in the future.

- fs.getCapacity just returns the capacity of the current drive, if
available. This will be nil on rom mounts.
- fs.attributes returns an lfs like table of various file attributes.
Currently, this contains:
- access, modification, created: When this file was last accessed,
modified and created. Time is measured in milliseconds since the
epoch, same as os.epoch("utc") and what is accepted by os.date.
- size: Same as fs.getSize
- isDir: same as fs.isDir
Closes#262
- contains now performs a case-insensitive comparison. While this is a
little dubious, it's required for systems like Windows, where foo and
Foo are the same folder.
- Impose a depth limit on copyRecursive. If there are any other cases
where we may try to copy a folder into itself, this should prevent
the computer entirely crashing.
- Remove *Stream methods on IMount/IWritableMount, and make the channel
ones the primary.
- Fix location of AbstractTurtleUpgrade
- Make IComputerAccess.getAvailablePeripheral and .getMainThreadMonitor
mandatory.
- IComputerAccess throws a specialised NotAttachedException
- Add a cc.pretty module, which provides a Wadler style pretty printer [1].
- The cc.pretty.pretty function converts an arbitrary object into a
pretty-printed document. This can then be printed to the screen with
cc.pretty.{write, print} or converted to a string with cc.pretty.render.
- Convert the Lua REPL to use the pretty printer rather than
textutils.serialise.

Unfortunately we can't apply the config changes due to backwards
compatibility. This'll be something we may need to PR into Forge.
CraftTweaker support still needs to be added.
Before it would remain the same across world reloads, and thus would be
out-of-date after leaving the first world. This architecture technically
allows for running multiple servers at once, though that's not going to
matter that soon.
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>.
- Adds cc.completions module, with a couple of helper functions for
working with the more general completion functionality (i.e. that
provided by read).
- Adds cc.shell.completions module, which provides shell-specific
completion functions.
- Add a "program completion builder", which allows you to write stuff
like this:
shell.setCompletionFunction( "rom/programs/redstone.lua",
completion.build(
{ completion.choice, { "probe", "set ", "pulse " } },
completion.side) )
Closes#232
