janet_vm_return_reg should only be set when janet_continue
is called. Otherwise, a panic may dump it's error message in
the wrong place, resulting in undefined behavior (often showing
the last return value or worse, segfaulting).
A lot of refactoring larger integer types. Fix a number
of casting errors, but mostly rename things. Also try to
limit use of template-like macros as they bloat the binary
if not used in moderation. We were able to reduce the size of
typed array code as well by using a single view types.
The break special form can break out of both loops
and functions with an early (nil) return. Mainly useful
for generated code in macros, and should probably be discouraged
in user written code.
Before, we used a local setjmp/longjmp for error handling.
Using janet_panic means errors can be more easily expressive and
code can be smaller.
However, we still need to make vector memory get gc collected, as
panics can cause the runtime to skip janet_v_frees.
We need to be able to detect tuple type from janet code, otherwise
tuples will contain hidden state. The tuple/type function is able
to detect the flags in the tuple so the programmer can access them
if needed.
The system path can more easily modified at runtime,
and the module/cache and module/loading tables are now exposed.
Properly cache native modules as well.
Disable tail calls in the root scope for better
stacktraces, as the root scope may contain a single call
to a failing function, as in the case of the test suite.
This allows that pattern to call an external function to
check if some text should match or not. This allows for
matching any possible language a computer can recognize.
to make janet function calls easier and faster from C (still
needs an object pool for fibers, though). Fix bug in scan-number
and add many more peg tests.
as back references for PEGs. More documentation is needed for PEG
syntax, but the amount required will need an external document, not
just a docstring.
