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.
Flychecking will now work correctly with arity checking, and
will better handle imports. Well structured modules should interact
cleanly with the flychecker in a mostly safe manner, but maliciously
crafted modules can execute arbitrary code. As such, the flychecker is
not a good way to validate completely untrusted modules.
We also extend run-context with an :evaluator option to replace
:compile-only. This is more flexible and allows users to create their
own flychecker like functionality.
This allows some more optimizations when printing to
buffers or when output is disabled. It also makes printf
more consistent with print and prin (Same with eprintf).
The print family of functions now writes output
to an optional buffer instead of a file bound to :out.
This means output can be more easily captured an redirected.
This should help catch a number of errors, but it
is a very shallow implementation of type checking. It will
catch some common misuses of functions at compile time
rather than runtime.
This will prevent these functions from being run
with empty strings, which usually produces useless
output, as the internal string search algorithm will
never "find" empty strings. This is by design, as it is
not always obvious which empty strings should be found in
the search text.
This should be friendlier to most users. It does, however, mean
we lose range information. However, range information could be
recovered by re-parsing, as janet's grammar is simple enough to do this.
Also adds the janet_lengthv API call. This is
needed because janet_length returns a 32 bit integer, where
as lengthv lets us return larger values (useful for typed arrays).
janet_mcall is an api function that should make it easier to call
a janet method from C code. It shares a similar signature with
janet_call.
Remove the multiple caching tables we were using
and use the grammar table for caching. This works
well because we can use raw_get for checking the local cache, and normal
get fro checking the global cache.
A keyword reference only counts as visited if we have
it as cached in the memoized->table, and we know it was
originally referenced from the same grammar table. If these
two conditions are true, then compilation must work correctly.
Also add janet_table_get_ex.
(backmatch [tag?]) is similar to a back reference in regular expressions
(NOT to backwards capture in a peg). It only matches a pattern if
it exactly matches the text of the last capture. It does not consume
or push any captures to the capture stack.
