The definition of '&&':
Return the first falsy value, or the last value, skipping the evaluation of other operands.
The definition of '||':
Return the first truthy value, or the last value, skipping the evaluation of other operands.
Toy now follows these definitions.
Fixed#154
The results can be found in
'tests/benchmarks/array_allocation/results.md'
The results are disappointing, as 'malloc()' is simply faster in every
possible situation compared to my custom arena allocator.
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?
I attempted to add '-Wpedantic' to CFLAGS, but it seems that my usage of
the variable length arrays within unions is causing an error that can't
be selectively disabled:
error: invalid use of structure with flexible array member [-Werror=pedantic]
This is the offending code: /source/toy_string.h#L9-L37
It seems that tagged unions, with VLAs within, is simply not allowed.
Unfortunately, my whole string system depends on it. I'll have to find some way
around it.
I've also updated the debugging output in repl/main.c.
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 was sidetracked by a strange display bug - turns out it was caused by
pointers - this commit fixes it.
The tests for if-then-else still aren't finished, but I'm knocking off
as it's past my time limit. I've marked 'TODO' and 'URGENT' using
comments, so finding the issues should be easy.
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
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
I was reworking bits of the containers to address issue #131, then
realized that the table's tests depended on a specific initial size. I'm
too buggered to finish it tonight, so I'll fix it tomorrow.
