Calvin Rose 9c14c09962 Add explicit stdatomic config setting for #1374 
There was some hacky workaround code for development versions of TCC
that interfered with other compilers and technically was not legal
c99.

Calvin Rose 609b629c22 Add support for atomic loads in Janet's atomic abstraction. 2023-10-21 10:40:57 -05:00
Calvin Rose e74365fe38 Be a bit safer with reference counting. 
We might want to revisit some uses of refcounts in the
ev module to be more efficient if we care about signal atomicity
(where memory order isn't really important) or multithreading atomicity.

Calvin Rose 6ae81058aa Be more consistent with va_arg types. 2023-10-08 19:09:35 -05:00
Calvin Rose af7ed4322e Get rid of req for 64 bit atomics 2023-10-01 10:27:51 -05:00
Calvin Rose 7cdd7cf6eb Expose atomic refcounts to be easier to port. 
This code was duplicate in a few places.

Calvin Rose 738fe24e6d Allow buffer/blit to take explicit nils for default args. 
Also small changes for range checking code.

Calvin Rose 3f7a2c2197 Try harder to avoid string copying with janet_getcbytes. 2023-06-28 08:30:09 -05:00
Calvin Rose f6248369fe Update janet_getcbytes to padd buffers with trailing 0. 2023-06-28 08:18:43 -05:00
Calvin Rose ff90b81ec3 Add some utilitites for dealing with unsigned integers in janet.h 2023-06-24 10:38:35 -05:00
Calvin Rose 19f14adb9e Update changelog. 2023-05-07 21:07:22 -05:00
Chloe Kudryavtsev 53ba9c800a Add get/opt cbytes 
Like getcstring, but operates on a byteview.
When writing bindings (i.e what capi.c is primarily used for), it's
common to want to accept a buffer *or* a string rather than just
a string.
For this, a byteview is perfect (and why not accept keywords while
you're at it?).
However, there's no built-in function for getting a cstring out of
a byteview, this adds one.
This also reformulates getcstring to be an edge-case of getcbytes
(simply adding an explicit check for stringness).

Calvin Rose 3715d7a184 Auto update copyright date. 2022-03-21 18:22:59 -05:00
Calvin Rose 1ef6db16ed Add janet_vm_save and janet_vm_load. 
This lets a user multiplex multiple Janet VMs on a single
thread or process if they are willing to implement context switching
themselves.

Calvin Rose 61cca10cf6 Allow iterating through the properties of core abstract types. 2021-01-11 23:14:07 -06:00
Calvin Rose 617ec7f565 Threading improvements. 
- Add thread/exit to kill the current thread.
- Add global lock aroung custom getline and add atexit handler
- to prevent any possible issues when exiting program.
- Allow sending stderr, stdout, and stdin over thread.
 2020-07-03 16:28:07 -05:00
Calvin Rose de9951594e Allow setting dynamic bindings at C top level. 
Before, these bindings we just ignored. However, it useful for
controlling janet_printf and janet_eprintf, for example. These can
be called from C code without being inside a call to janet_continue.
 2020-06-22 08:56:04 -05:00
Calvin Rose b1f76139a7 Add several configurable options - #379 2020-05-09 12:00:01 -05:00
Calvin Rose 605a205008 Range errors for `slice`-likes include negatives. 
Makes for less confusing errors when calling something
like `(slice [] 0 -10)`.
 2020-04-14 21:27:48 -05:00
Calvin Rose 71882475d6 janet_formatb -> janet_formatbv, new janet_formatb 
The old function was not very useable. In the likely
case that there is no external code using this
(not well documented/janet_formatc is more convenient), we
can change this.

Calvin Rose a68ee7aac6 Update Copyright 2020. 2020-01-12 10:50:37 -06:00
Calvin Rose 3d40c95e80 Add ability to Janet signal from C functions. 
While C functions are not re-entrant, signaling from a C function
can be used to implement async returns. When resuming a fiber that
signalled from within a C function, the fiber is started after the
instruction that emitted the signal. The resume argument is used
as the return result from the c function.

Calvin Rose ed5027db5d Address #242 
Synchronize critical sections in setenv/getenv/environ.
 2020-01-06 22:41:18 -06:00
Calvin Rose 9dd152dc28 Add features.h for feature test macros. 
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.
 2019-12-30 19:06:15 -05:00
Calvin Rose 4238379552 Use _setjmp/_longjmp on BSDs. 
This doesn't save the signal mask so should be a bit faster.
 2019-12-18 12:18:31 -05:00
Calvin Rose bc8ee207d5 Address #219. 
Adds several shorthands to the C API.
 2019-12-14 11:31:46 -06:00
Calvin Rose 8700a407ce Update janet_getmethod to better match new get api. 2019-12-09 18:45:05 -06:00
Calvin Rose 1f55d40a10 Fix janet_opt* api. 
Inverted conditional made behavior incorrect. These
were not used in the core library, so were not tested.
 2019-11-09 09:39:14 -06:00
Calvin Rose aee1687215 Add RNG functionality to the math/ module. 
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.
 2019-11-08 17:40:04 -06:00
Calvin Rose d47804d222 Add prin, eprint, and eprin functions. 
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.
 2019-10-19 09:44:27 -05:00
Calvin Rose 944347e828 Fix formatting. 
Run make format.
 2019-09-30 20:00:29 -05:00
Calvin Rose 339dea9390 Add optional argument functions to c api. 
These are just helpers to make parameters than can be nil with a
default value easier to handle in a consitent way.
 2019-09-24 19:40:49 -05:00
Calvin Rose 2193193b12 Improve error message on bad method calls. 2019-08-05 19:06:58 -05:00
Calvin Rose 850a2d7f79 Allow method calls on typed arrays. 2019-08-05 18:51:53 -05:00

Calvin Rose 3598f056bb Reformat capi.c 2019-06-15 11:04:24 -04:00
Calvin Rose 82edc19137 Update cook to take headers for natives. 
This should help incremental building.
 2019-06-13 00:41:20 -04:00
Calvin Rose 5689ef1af1 Add keyword flag utility for modules. 2019-06-12 12:05:48 -04:00
