A finalizer can be attached to scratch allocations efficiently at any point in
it's lifecycle via janet_sfinalizer. Care was taken to keep allocations aligned
with platform alignment requirements.
A big drawbacks to this approach is the waste of up to 16 bytes per scratch
allocation in the case the scratch memory does not require a finalizer.
doc macro can take no arguments and print out
all bindings. Fix an issues with the vm skipping
over a breakpoint in some situations.
Add examples/debugger.janet for proof of concept
debugger.
When file was created with file/popen, the current optimization
of using fseek on windows fails due to windows not properly returning
and error code and just returning 0. Windows :(.
The new RNG wraps up state for random number generation, so
one can have many rngs and even marshal and unmarshal them.
Adds math/rng, math/rng-uniform, and math/rng-int.
Also introduce `in` and change semantics for
indexing out of range. This commit enforces stricter
invariants on keys when indexing via a function call
on the data structure, or the new `in` function.
The `get` function is now more lax about keys, and will
not throw an error when a bad key is used for a data structure, instead
returning the default value.
This helps for temporarily setting vars in a safe
manner that is guaranteed not to leave vars in a bad state
(assuming that a fiber does not emit debug or use signal and
is never resumed).
This allows easy builds of the full interpreter with no
build system.
1. Get janet.c, janet.h, janetconf.h, and shell.c in a directory. Edit
janetconf.h as desired.
2. gcc shell.c janet.c -lm -ldl -O2 -o janet (on GNU-Linux for example)
3. ./janet -h (Yay!)
This makes it easier to get the CLI functionality when
embedding Janet, although the main reason is the init script
is now pre-compiled to bytecode when generating the boot image.
