Toy now fits into the C spec.
Fixed#158
Addendum: MacOS test caught an error:
error: a function declaration without a prototype is deprecated in all versions of C
That took 3 attempts to fix correctly.
Addendum: 'No new line at the end of file' are you shitting me?
Getting the array's length is still not available yet, so I'm not
marking arrays as done - but everything that is there is tested.
I've also tweaked the assert output callbacks to also print 'assert failure'.
I had intended to solve the Advent of Code puzzles in Toy, but they
don't work without arrays. I wasn't able to enable arrays in time, so
I need to focus on doing things correctly.
The most immediate tasks are marked with 'URGENT', and a lot of tests
need writing.
I've brought the tests up to scratch, except for compounds im the
parser, because I'm too damn tired to do that over SSH. It looks like
collections are right-recursive, whixh was unintended but still works
just fine.
I've also added the '--verbose' flag to the repl to control the
debugging output.
Several obscure bugs have been fixed, and comments have been tweaked.
Mustfail tests are still needed, but that's a low priority. See #142.
Fixed#151
The assert keyword works, but I want to add a cmd option to suppress or
disable the errors.
The tests need some serious TLC. I know that, but I'm kicking it down
the road for now.
I was coding earlier this week, but my brain was so foggy I ended up not
knowing what I was doing. After a few days break, I've cleaned up the
mess, which took hours.
Changes:
* Variables can be assigned
* Added new value types as placeholders
* Added 'compare' and 'assign' to the AST
* Added duplicate opcode
* Added functions to copy and free values
* Max name length is 255 chars
* Compound assigns are squeezed into one word
To be completed:
* Tests for this commit's changes
* Compound assignments
* Variable access
To help with storing strings within tables, I've replaced the unused
'_padding' member of 'Toy_String' with 'cachedHash', which is set to
zero on string allocation.
The hash of a string isn't generated and stored until it's actually
needed, as the rope pattern means not every string needs a hash -
hopefully this will save unnecessarily wasted time.
When a hash of a string is needed, the hashing function first checks to
see if that string already has one, and if so, returns it. Again, less
time wasted.
When generating a new string hash, the hashing function takes the
string's type into account, as node-based strings first need their
contents assembled into a simple char buffer.
Other changes include:
* Changed 'TOY_VALUE_TO_*' to 'TOY_VALUE_FROM_*'
* Changed 'TOY_VALUE_IS_EQUAL' to 'TOY_VALUES_ARE_EQUAL'
* Added a missing '#pragma once' to 'toy_print.h'
The following structures are now more independant:
- Toy_Array
- Toy_Stack
- Toy_Bucket
- Toy_String
I reworked a lot of the memory allocation, so now there are more direct
calls to malloc() or realloc(), rather than relying on the macros from
toy_memory.h.
I've also split toy_memory into proper array and bucket files, because
it makes more sense this way, rather than having them both jammed into
one file. This means the eventual hashtable structure can also stand on
its own.
Toy_Array is a new wrapper around raw array pointers, and all of the
structures have their metadata embedded into their allocated memory now,
using variable length array members.
A lot of 'capacity' and 'count' variables were changed to 'size_t'
types, but this doesn't seem to be a problem anywhere.
If the workflow fails, then I'll leave it for tonight - I'm too tired,
and I don't want to overdo myself.
At this point, only a minimal number of operations are working, and
after running any kind of source code, the 'result' is simply left on
the VM's stack. Still, it's awesome to see it reach this point.
