Support looking up missing symbols during compilation 2022-01-21 13:07:11 +09:00
Calvin Rose 5b5a7e5a24 Make top level vars reuse ref cell when redefined at the top level. 
This improves the repl experience while not messing with existing code
very much, if at all.

Calvin Rose f9891a5c04 More improvements to hashing for #889 2021-12-06 17:23:00 -06:00
Calvin Rose 545c09e202 Update hash mixing behavior - address #889 
Try to have better behavior when mixing sub-hashes that are not uniform and
randomly distributed. Premultiply by a large prime before mixing to
"spread entropy" if it is concentrated in a certain subset of bits.

bakpakin 7734e77dfc Readd the janet_register function. 2021-08-22 10:38:15 -05:00
Calvin Rose bd71e1cd02 Silence clang warning about comparing function pointers. 
The comparison is used to create a set of function pointers.

Calvin Rose 7f7ee75954 Patch util.c 2021-07-31 10:00:43 -05:00
Calvin Rose 7e5f226480 Put source mapping info in stack traces. 2021-07-29 21:29:08 -05:00
Calvin Rose eb84200f28 Fix linux issues with epoll on normal files. 
We use the selfpipe trick if epoll fails with EPERM when trying to
register a file descriptor.
 2021-07-25 21:47:52 -05:00
bakpakin 7fba44ccce Add macro mechanism for defining C source information for functions. 
This wil let us track source code for C functions more easily.
 2021-07-25 13:03:01 -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 60214dc659 Update for windows compiler warning. 2021-05-30 16:42:58 -05:00
Calvin Rose 1f4f69a5b6 Fix windows syntax issue. 2021-05-29 20:40:26 -05:00
Calvin Rose 7ff204ec44 Work on system for adding compiler warnings. 
This is the beginning of a system for compiler warnings. This includes
linting, deprecation notices, and other compiler warnings that are best
detected by the `compile` function and don't require the partial
evalutaion of the flychecker.

Calvin Rose a2c837a99c Merge remote-tracking branch 'felixr/master' into master 2020-12-26 20:06:34 -06:00
Felix Riedel c76e0ae685 Use boost's way of combining hash values for arrays and kv pairs. 
`seed ^= hash_value(v) + 0x9e3779b9 + (seed << 6) + (seed >> 2);`
from https://www.boost.org/doc/libs/1_35_0/doc/html/boost/hash_combine_id241013.html

The current way of combining hashes peforms poorly on hash values of
numbers. Changing the way hashes are combined canlead to a significant speed up:

```
time janet_new -e '(def tbl @{}) (loop [x :in (range 1000) y :in (range 1000)] (put tbl {0 x 1 y} true))'
3.77s user 0.08s system 99% cpu 3.843 total

time janet_orig -e '(def tbl @{}) (loop [x :in (range 1000) y :in (range 1000)] (put tbl {0 x 1 y} true))'
48.98s user 0.15s system 99% cpu 49.136 total
```

Calvin Rose ebfa07f8ce Registering an abstract type is idemptotent. 2020-10-06 19:11:29 -05:00
Calvin Rose b53890ddae Make some changes for WASM build. 2020-09-07 16:08:43 -05:00
Calvin Rose 70ad98cc6f Fix arc4random_buf implementation. 2020-08-03 21:49:49 -05:00
Andrew Chambers 4d4ca7bb36 Initialize PRF with random data when it is enabled. 2020-08-04 12:13:36 +12:00
Calvin Rose ba08e487cb Disable PRF by default. 
Since it is not any better by default without initializing the key, we
disable it by default. It can be turned on with JANET_PRF in
janetconf.h.

Calvin Rose 4721337c7c issues with gettime on mach kernel. 2020-07-03 20:19:36 -05:00
Calvin Rose 3bb8f1ac8d Don't use CLOCK_MONOTONIC for pthread stuff. 
Also fix marshalling functions without full
sourcemapping information, as well as thread/receive
ignoring bad messages. Instead, thread/receive will error
on bad messages.
 2020-07-03 19:54:58 -05:00
Calvin Rose 55cf9f5e1c Don't break reverse backwards compat. 
Breaking backwards compatibiliy here is not worth it.
Also update changelog.
 2020-07-03 10:17:50 -05:00
Calvin Rose b89f0fac7b Move clock shims to util (Helps #430). 
The thread module should also use these clock shims rather
than clock_gettime, which is not available on older mac systems.
 2020-07-03 09:54:58 -05:00
Calvin Rose 51ff43e2f2 Update range checks for 64 bit integers. 2020-06-27 11:23:47 -05:00
Calvin Rose fbe903b277 Add janet_cfuns_prefix to janet.h 
Makes adding functions to the current environment easier.
 2020-04-17 13:37:52 -05:00
Calvin Rose a3aaa6634d Use separate registry table for abstract types. 
This avoids overloading the registry table, which is intended
for names of c functions.
 2020-03-14 10:25:39 -05:00
Calvin Rose 6a3a983f43 Expose abstract type definitions in janet.h 
This makes certain operations easier, and allows
more access to built in APIs.
 2020-03-14 10:12:47 -05:00
Calvin Rose 333ae7c4f8 Make amalgamtion the default when building. 
This way we can support fewer build configurations. Also, remove
all undefined behavior due to use of memcpy with NULL pointers. GCC
was exploiting this to remove NULL checks in some builds.
 2020-01-28 23:38:52 -06:00
Calvin Rose 2dd852da54 Use ATEND macros to add fields to abstract types. 
This means we can add new properties to abstract types without
breaking old code. We can also make simple abstract types without
needing to add many NULL fields to the type.
 2020-01-20 13:06:50 -06:00
Calvin Rose f4077b678a Allow calling next on abstracts. 
This will allow the creation of infinte
streams, low cost generators, etc.

Make hash api more future proof.
 2020-01-18 09:45:47 -06:00
Calvin Rose a8e4c4bed0 Add special forms and sort completions. 
Also fix case when no completion is needed.
