This is mainly meant for use as the entry point to a C wrapper for a
janet program. This maeans the programmer doesn't need to use an ifdef
to handle if the event loop is enabled.
This should make its use a little more robust for
simple usage. To avoid printing to stderr, use
janet_table_put(env, janet_ckeywordv("err"), janet_wrap_false());
Like eachk and eachp, use eachy and repeat to bring loop
verbs outside of the loop macro. These new macros are very simple
and easy to understand, in contrast to the loop macro which is of
medium complexity.
Required a few changes to APIs, namely janet_root_fiber()
to get topmost fiber that is active in the current scheduler.
This is distinct from janet_current_fiber(), which gets the bottom
most fiber in the fiber stack - it might have a parent, and so cannot
be reliably resumed.
This is the kind of situation that makes symmetric coroutines more
attractive.
Because we use an amalgated build, feature
test macros should be set in a single file that
is included before any other headers, and is placed
at the top of the amalgamated build.
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.
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.
- 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
If a comment is not followed by a newline character, then
we got a false parse error. This is because the comment
state is left on the parse stack when we finished parsing, and
since the parse stack was not emtpy, we assumed an error.
This commit adds the parser/eof function, which lets the parser know
that an eof was reached. Before, we simply added a fake newline
character in some cases, and in the case of reading a file, we did
nothing, hence the bug.
There was an implementation for stacktraces in both
run.c and in core.janet, status-pp. The commit removes
the one in core.janet in favor of the C based stacktrace, which
is exposed via debug/stacktrace. Lots of reshuffling of run-context
ensued as well, which resulted in an api that is a bit cleaner.
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.
