- 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 a backport of 1.15's terminal rendering code with some further
improvements. This duplicates a fair bit of code, and is much more
efficient.
I expect the work done in #409 will supersede this, but that's unlikely
to make its way into the next release so it's worth getting this in for
now.
- Refactor a lot of common terminal code into
`FixedWithFontRenderer`. This shouldn't change any behaviour, but
makes a lot of our terminal renderers (printed pages, terminals,
monitors) a lot cleaner.
- Terminal rendering is done using a single mode/vertex format. Rather
than drawing an untextured quad for the background colours, we use an
entirely white piece of the terminal font. This allows us to batch
draws together more elegantly.
- Some minor optimisations:
- Skip rendering `"\0"` and `" "` characters. These characters occur
pretty often, especially on blank monitors and, as the font is empty
here, it is safe to skip them.
- Batch together adjacent background cells of the same colour. Again,
most terminals will have large runs of the same colour, so this is a
worthwhile optimisation.
These optimisations do mean that terminal performance is no longer
consistent as "noisy" terminals will have worse performance. This is
annoying, but still worthwhile.
- Switch monitor rendering over to use VBOs.
We also add a config option to switch between rendering backends. By
default we'll choose the best one compatible with your GPU, but there
is a config option to switch between VBOS (reasonable performance) and
display lists (bad).
When benchmarking 30 full-sized monitors rendering a static image, this
improves my FPS[^1] from 7 to 95. This is obviously an extreme case -
monitor updates are still slow, and so more frequently updating screens
will still be less than stellar.
[^1]: My graphics card is an Intel HD Graphics 520. Obviously numbers
will vary.
This would return true for any block with a fluid in it, including
waterlogged blocks. This resulted in much broken behaviour
- Turtles cannot place blocks when waterlogged (fixedd #385)
- Turtles could move into waterlogged blocks (such as fences),
replacing them.
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
It hasn't been http_enable for yonks - slightly worried I didn't notice
this earlier.
Also don't refer to ComputerCraft.cfg - the name has changed several
times across versions, so let's leave it ambiguous.
Hopefully provides a /little/ more information about the build process.
Hey, also means I only need to add a CoC to complete GH's community tab!
In all seriousness, there's probably a lot more I need to flesh out
here, such as some kind of vision and guides for issues/PRs. But this at
least documents the local development process. Somewhat.
- 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.

This means we are already provided with file attributes, which halfs[^1]
the time taken to scan folders.
[^1]: This dropped the fastest scan time from ~1.3s to ~0.6. It's by no
means a perfect benchmark, but this is still an obvious improvement.
- 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
- Move timer handling to IAPIEnvironment, rather than OSAPI. This means
the environment is reset on startup/shutdown, much like normal APIs.
- Websocket.receive now accepts an optional timetout (much like
rednet.receive). This starts a timer, and waits for it to complete.
Closes#201
- 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.
See #354
- Remove Lua script to generate recipes/advancements for coloured
disks, turtle upgrades and pocket upgrades. Replacing them with Lua
ones.
- Generate most block drops via the data generator system. Aside from
cables, they all follow one of two templates.
- 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
Most of the port is pretty simple. The main problems are regarding
changes to Minecraft's rendering system.
- Remove several rendering tweaks until Forge's compatibility it
brought up-to-date
- Map rendering for pocket computers and printouts
- Item frame rendering for printouts
- Custom block outlines for monitors and cables/wired modems
- Custom breaking progress for cables/wired modems
- Turtle "Dinnerbone" rendering is currently broken, as normals are not
correctly transformed.
- Rewrite FixedWidthFontRenderer to to the buffer in a single sweep.
In order to do this, the term_font now also bundles a "background"
section, which is just a blank region of the screen.
- Render monitors using a VBO instead of a call list. I haven't
compared performance yet, but it manages to render a 6x5 array of
_static_ monitors at almost 60fps, which seems pretty reasonable.
- 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.
