For to and thru, we need to restore eveytime through the loop since rules need
run with the right captures on the stack, especially if they have any
sort of backrefs.
While generally we are not in the business of making a very chatty
compiler, this is a simple improvement that involves compiling
metadata before the binding, as well as adding a suggestion for `defn`
in case the compiler encounters an unexpected tuple.
Added some backticks around code in docstrings to distinguish them from prose.
Light editing to `table/raw-get`. Is my change there correct? (t --> the key)
Buffers make more sense for this function because one of their primary
use cases is working with bytes.
The tuple implementation was an array of floats, which is less
performant and ergonomic for common operations. (i.e: bit manipulation)
Buffers also have the advantage they are mutable, meaning the user
can write ints to an existing buffer.
Previously int/to-number would fail if the input was outside
the range of an int32.
Because Janet numbers are doubles,
they can safely store larger ints than an int32.
This commit updates int/to-number to restrict the
value to the range of integers a double can hold, instead of an int32.
(int/to-number value) converts an s64 or u64 to a number.
It restricts the value to the int32 range,
so that `int32?` will always suceeded when called on the result.
This is more intuitive and avoids the possibilty of strange code
to resume or cancel a fiber after it was scheduled but before it was
entered for the first time.
The main issue was cancellation of fiber using `cancel` rather than
`ev/cancel` could cause issues with the event loop internal ref count.
Since this is almost certainly bad usage (and is not something I want to
encourage or support), we will warn against trying to resume or error
fibers that have already been suspended or scheduled on the event loop.
The distinction between "task" fibers and normal fibers is now kept by a
flag that is set when a fiber is resumed - if it is the outermost fiber
on the stack, it is considered a root fiber. All fibers scheduled with
ev/go or by the event loop are root fibers, and thus cannot be cancelled
or resumed with `cancel` or `resume` - instead, use `ev/cancel` or
`ev/go`.
Nested expression in the quasiquote were being compiled with the "hint"
flag passed to the expression compilation, essentially telling the
compiler to put intermediates into the final slot, possibly overwriting
other intermediate values. This fix removes that flags on any recursive
calls to quasiquote.
