The janet_get_permissive function implements the core semantics
of the 'get' function. The original janet_get implements the semantics of
the 'in' function and also the OP_GET opcode. This slight oddity is
to avoid a backwards incompatible change.
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.
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.
Mostly changes to cook and jpm. Also some
code for file associations in the windows installer, and
adding the :linux value from os/which (instead of just :posix).
This allows better stacktraces when manually intercepting
signals to clean up resources. Also allows functionality
from Common Lisp's unwind-protect, such as calling cleanup code
while unwindinding the stack, restarting on certain signals, and
just in general having more control over signal and signal propagation.
Also fix a bug encountered while implementing with-resource in the
compiler. Desturcturing arguments that were not the last argument
would often result in bad code generation, as slots used to destructure
the earlier arguments would invalidate the later parameters. This is
fixed by allocating all named parameters before doing any destructuring.
- Allow passing a table to fibers, which make fiber level scope easier.
- Add fiber/getenv, fiber/setenv, dyn, and setdyn
- Remove meta, *env*, and *doc-width*
- Some functions changed dignatures, and no longer take an env
Rather than edit the Makefile or the janet.h header yourself, use
janetconf.h to configure builds. This has the benefit of making it
easier to configure janet in a persitent but easy way.
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.
Allow overriding functions in the core libray to provide better
functionality on startup. Used to include our getline function in
the repl but use a simpler version in the core library.
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.
A consistent style should help with contributors and
readability. We use astyle as the formatter as can make a pretty
good approximation of the current style and my preferred style.
Astyle can be found at http://astyle.sourceforge.net/astyle.html
This should speed up start time and reduce malloc/free
usage to about 15% of what is what previously for startup.
The current cost is slightly larger binary as the representaion
of the image is currently less compact than source code.
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.
