Previously it was possible to access all methods of the multishell
redirect by calling term.current(). This is definitely not intended, as
it leaks all sorts of internals to the user.
Also bump illuaminate - the new version is about twice as fast on my
machine.
Woops!
- Fix the REPL not printing values, as exception.try didn't return
values. It did originally, and then I tried to simplify it >_>
- Change repl_exprs to run an expression and program parser in
parallel, rather than handling the parallelism on the grammar side -
that has a few shift/reduce conflicts which result in bad parse
errors.
- Bump Cobalt to 0.6.0. We now track both line and column numbers of
each bytecode instruction, allowing us to map an error to a concrete
position.
- `loadfile` (and similar functions) now use the full path, rather than
the file name. Cobalt truncates this to 30 characters (rather than
the previous 60) so this should be less noisy.
- The shell, edit and Lua REPL now display the corresponding source
code alongside an error.
Note this is incredibly limited right now - it won't cope with errors
which cross coroutine boundaries. Supporting this is on the roadmap,
but requires some careful API design.
While it's a nice immersive interaction, it's far too easy to trigger by
accident. Dying/undying can now only be done via crafting and the
cauldron.
Closes#1321
It's much less aggressive than dunking it in a cauldron, so won't damage
any of your precious electronics.
I had this idea back in 2017 (dan200/ComputerCraft#230). Can't believe
it took me almost 6 years to implement.
In older versions we just used a hard-coded list of items and
superclasses. This was somewhat ugly, and so in 1.19.3 I tried to make
this code more generic.
However, this has a lot of unintended consequences - for instance
turtles can now throw ender pearls, which is definitely not intended!
By using a tag, we can emulate the old behaviour, while still allowing
modders and pack devs to add additional items if needed.
- Encode the DFA as a virtual machine (identical to lrgrep) rather than
compiling it to a series of Lua functions. While this is a little
slower and uglier, it's much more space efficient, shaving off 16Kb.
- Minimise the DFA properly. This only shaves off a few states, but
every little helps.
- Run the error handling code from a non-reduced parser stack. This was
incredibly nasty to get right (and positions are still not correctly
handled), but it fixes several broken error messages.
- Move modem recipes out of the usage section.
- Add missing argument names to BinaryWriableHandle.write. Illuaminate
really should catch this, but for now I did a grep and couldn't find
any more instances of this.
- Add several (internal) modules for lexing and parsing Lua code. These
allow us to provide (hopefully) higher quality error messages than
Lua's built-in messages.
- `shell.run`, `edit` and `lua` now use this parser when fed invalid
code. This allows us to provide better syntax errors, while not
having any impact on the happy path.
Note this does not affect any other mechanism for loading code
(`load`, `require`, `dofile`).
There's still a lot of work to do here in improving error message
quality, but hopefully this provides a good starting point.
- Document the thread safety of DetailRegistry a little better.
- Turtles now duplicate their inventory to the "previous
inventory" (now called inventorySnapshot) immediately, rather than
when the block is ticked.
This is slightly more resource intensive, but I don't think it's so
bad we need to worry.
- As this snapshot is now always up-to-date, we can read it from the
computer thread. Given the item is immutable, it's safe to read NBT
from it.
_Technically_ this is not safe under the Java memory model, but in
practice I don't think we'll observe the wrong value.
Closes#1306
Just ran[^1] over the codebase. Turns out we'd duplicated one of the
changelog entries entirely - I suspect due to a version merge gone
wrong!

When the peripheral is attached, we add the computer to the map and
queue the actual disk to be mounted next tick. This avoids the
thread-safety issues with mutating the item (and creating disk ids) that
might be caused by doing it on the computer thread.
The mount is now also managed separately to the MediaStack, as that was
meant to be an immutable snapshot of the item!
Fixes#1282
This gives us slightly better guarantees that the config has actually
been loaded. This, along with a FCAP bump, fixes this config option
not doing anything on Fabric.
