Calvin Rose aa5c987a94 Change semantics of bracketed tuple equality. 
Comparison between different bracket and normal tuples
will now take into account the delimiter type. This solves strange
non-locality issues in the compiler due to this false equality, and is
more consistent with Janet's otherwise strong equality philosophy.

Calvin Rose ef85b24d8f Add optional offset to ffi/write. 2023-02-12 12:08:28 -06:00
Calvin Rose c55d93512b Add buffer/push-at for easier manipulation of buffers 
buffer/blit is difficult to use, and while buffer/push is the easiet
buffer manipulation function to use it only appends to the buffer.
buffer/push-at lets users manipulate buffers at any index - useful
for buffers used as an in-memory databases, for example.

Calvin Rose 2e38f9ba61 Allow passing pointer-buffers to other threads. 2023-02-12 11:07:45 -06:00
Calvin Rose 1cadff8e58 Add ffi/pointer-buffer for easier memory manipulation in FFI. 
Added underlying buffer support for buffer instances that cannot
reallocated underlying memory - useful for (small) memory mapped
files and other FFI utilties.

Calvin Rose b032d94877 Add sandboxing API. 
The sandboxing API is meant to make janet a bit more attractive
for certain application embedding use cases. The sandboxing API
puts limits on what system resources the interpreter can access.

Calvin Rose a0f40042cb Update copyright year. 2023-01-07 15:03:35 -06:00
Calvin Rose d5ee6cf521 Add malloc and free to ffi. 
Very "unsafe", but a good tool of last resort. In most cases
a buffer is preferable, but the lifetime can be a bit unclear.
This allows very granular control over memory.

Calvin Rose a1172529bf Fix named arguments with optional args. 2022-06-18 09:46:28 -05:00
Calvin Rose c9586d39ed Add a :none calling convention. 
The ffi module is useful even when true ffi calls
are not yet implemented. This lets the ffi be enabled
on any architecture, albeit with a degraded feature set
where calling conventions are not implemented.
 2022-06-12 10:12:45 -05:00
Calvin Rose 2e9f67f4e4 Change all "native-*" to ffi/. Move new dll loading funcs. 
native-close, raw-native and native-lookup have become
ffi/close, ffi/native, and ffi/lookup instead.

The new ffi module will be useful for any architecture even if we don't
support making calls to certain functions. We can simple add a
do-nothing calling convetion that panics on call. ffi/read and ffi/write
are useful in their own right.
 2022-06-12 10:02:02 -05:00
Calvin Rose e318170fea Begin working on windows calling convetion.

Calvin Rose 181f0341f5 Add :pack and :pack-all keywords to allow for struct packing. 
Syntax may need some work but covers both fully packed structs
as well as packing of individual members.
 2022-06-10 18:53:22 -05:00
