The biggest problem was simply that the length of children expansions was
not accounted for when skipping over the parent... this took a lot of
arduous debugging, but it finally works!
And fix line counting with expansion-made newlines.
This has the same bug as the old lexer (equs-newline's output does not
print the second warning as being part of the expansion).
Additionally, we regress equs-recursion, as we are no longer able to
catch this specific EQUS recursion. Simply enough, the new expansion
begins **after** the old one ends! I have found no way to handle that.
Add keywords and identifiers
Add comments
Add number literals
Add strings
Add a lot of new tokens
Add (and clean up) IF etc.
Improve reporting of unexpected chars / garbage bytes
Fix bug with and improved error messages when failing to open file
Add verbose-level messages about how files are opened
Enforce that files finish with a newline
Fix chars returned not being cast to unsigned char (may conflict w/ EOF)
Return null path when no file is open, rather than crash
Unify and improve error printing slightly
Known to be missing: macro expansion, REPT blocks, EQUS expansions
This requires some special-casing for `jr @` because the `jr` opcode has
already been emitted, but not the operand, so PC points to the middle.
Moved the RGBLINK test to RGBASM's folder, and created a new RGBLINK test.
The code expected to never get "known" expressions passed in, as RGBASM
otherwise patches the bytes in by itself; however, JR cannot be patched in
by RGBASM unless the section's base address is known as well!
This allows whitespace between the brackets and the register.
This also fixes#531
Note that `$ff00 + c` is still treated as a single token, because trying to
use an expression on the left side causes a shift/reduce conflict.
This isn't great, but most people seem to be either used to it as-is, or
using the new `ldh a, [c]` syntax.
If this causes problems with a lexer rewrite, it'll be deprecated; but for
now, keep it around, as the support is clunky but bearable.
Create a new file, platform.h, for platform-specific hacks
for MSVC, this includes defining strncasecmp to _stricmp and
strdup to _strdup, among other things like defining missing
stat macros
Change some things not supported in MSVC, like _Static_assert,
to their counterparts (in this case, static_assert)
Replace usage of VLAs with malloc and free
Update getopt_long and use the getopt implementation from musl
on Windows.
Use comments to show which functions from platform.h are being used
GCC with the -std=c11 defines __STRICT_ANSI__. DJGPP checks if
__STRICT_ANSI__ is defined and if so doesn't define some things
mandated by POSIX such as struct stat, PATH_MAX, and others.
The -std=gnu11 option does not define this macro, so use it instead.
_DEFAULT_SOURCE isn't needed as no GNU nor BSD-specific functions
are used. Remove it.
Fix the last two occurrences of incorrect format specifiers for standard
fixed-width integer types.
`macro_GetArg` had not been changed after the previous commit; however,
the old code relied on the `macroArgs->args` array being at least
`MAXMACROARGS` entries large (which was the case until the last commit).
The boundary against which it checked would have better been written as
`sizeof(macroArgs->args)/sizeof(macroArgs->args[0])`, I guess, but what's
done is done.
