a28053d4e9 Reworked Toy_String as a union, enabled -Wpedantic
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?

62ca7a1fb7 WIP: Implementing arrays into the script, read more
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.

2f9489d5fd Fixed a 'malformed assignment' issue, read more
I've also added some support for compiler errors in general, but these
will get expanded on later.

I've also quickly added a valgrind option to the tests and found a few
leaks. I'll deal with these later.

Summary of changes:

* Clarified the lifetime of the bytecode in memory
* Erroneous routines exit without compiling
* Empty VMs don't run
* Added a check for malformed assignments
* Renamed "routine" to "module" within the VM
* VM no longer tries to free the bytecode - must be done manually
* Started experimenting with valgrind, not yet ready

be7e4ddd18 Reworked the tests, read more
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

Other changes include:

* Added Toy_initVM(), to allow Toy_resetVM() to retain memory
* Added tests that reset and reuse the same VM

4bcf8e84a9 String literals are being parsed, compiled and printed, read more
Strings, due to their potentially large size, are stored outside of a
routine's code section, in the data section. To access the correct
string, you must read the jump index, then the real address from the
jump table - and extra layer of indirection will result in more flexible
data down the road, I hope.

Other changes include:

* Added string concat operator ..
* Added TOY_STRING_MAX_LENGTH
* Strings can't be created or concatenated longer than the max length
* The parser will display a warning if the bucket is too small for a
  string at max length, but it will continue
* Added TOY_BUCKET_IDEAL to correspend with max string length
* The bucket now allocates an address that is 4-byte aligned
* Fixed missing entries in the parser rule table
* Corrected some failing TOY_BITNESS tests

Also renamed 'handles' throughout the project for consistency.

Some meta files also had their file extensions added.

7b453bc35f Reworked generic structures, read more
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.

8d6bdb88b4 Implemented and tested Toy_String, read more
Strings are needed for the handling of identifiers in the key/value
variable storage, so I've got them working first. I used the rope
pattern, which seems to be quite an interesting approach.

I'll add comparison checks later.

Adjusted how buckets are handled in all tests, could've been an issue
down the line.

Added the build instructions to README.md.

c518960171 Toy_VM and Toy_Stack are working and tested, read more
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.
