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.
GPS requests are now sent and received on CHANNEL_GPS by default
instead. This means it should not be possible to distinguish
computers (and thus locate them) via their GPS requests.
"exit" now has a custom __tostring method, which prints an explanation
message. This is very similar to how Python achives the same
functionality:
lua> exit
Call exit() to exit
lua> exit()
> Actually leaves the REPL
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.
We now use illuaminate[1]'s linting facilities to check the rom and
bios.lua for a couple of common bugs and other problems.
Right now this doesn't detect any especially important bugs, though it
has caught lots of small things (unused variables, some noisy code). In
the future, the linter will grow in scope and features, which should
allow us to be stricter and catch most issues.
As a fun aside, we started off with ~150 bugs, and illuaminate was able
to fix all but 30 of them, which is pretty neat.

- 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
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.
This moves expect from the bios into a new craftos.expect module,
removing the internal _G["~expect"] definition. Apparently people were
using this irrespective of the "don't use this" comment, so we need to
find another solution.
While this does introduce some ugliness (having to load the module in
weird ways for programs, duplicating the expect function in memory), it
does allow people to use the function in a supported way, and removes
the global ugliness.
