The old math functions from quake and quakeworld don't belong with the
newer ones as their presence in the same object file causes invalid
builtin warnings when pr_cmds isn't present.
With some hacks that are not included (plan on handling events and
contexts properly), button inputs, including using listeners, are
working nicely: my little game is working again. While the trampoline
code was a bit repetitive (and I do want to clean that up), connecting
button listeners directly to Ruamoko instance methods proved to be quite
nice.
After seeing set_size and thinking it redundant (thought it returned the
capacity of the set until I checked), I realized set_count would be a
much better name (set_count (node->successors) in qfcc does make much
more sense).
For now, just bsearch (normal and fuzzy), qsort, and prefixsum (not in
C's stdlib that I know of, but I think having native implementations of
float and int prefix sums will be useful.
I can't say that I like what's there even now, but at least PLItem can
be used without a lot of casting. Really, Ruamoko needs dictionary and
string classes so reading a property list can build more natural object
trees rather than this mess from when I knew too little.
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
Returning a string was a bad idea as it makes str_str difficult to use
with str_mid. (actually, iirc, it was the only reason I moved all
strings into progs memory... hmm).
It never really helped sort out the path issues when using build
directories. It worked well enough for single directory projects, but
things got messy very quickly, especially when mixing ruamoko libs with
external progs. A better method based on dwarf is coming.
In testing variable fw/precision in PR_Sprintf, I got a nasty reminder
of the limitations of the current progs ABI: passing @args to another QC
function does not work because the args list gets trampled but the
called function's locals. Thus, the need for a va_copy. It's not quite
the same as C's as it returns the destination args instead of copying
like memcpy, but it does copy the list from the source args to a
temporary buffer that is freed when the calling function returns.
Changing str_free's return type highlighted that I'd missed an edit when
I did the big ruamoko build cleanup.
Also silence the sed/mv noise now that things are working nicely.
This returns the character (as an int) at the index. Equivalent to
string[index], but qc code doesn't have char-level access and not having
it means that strings can internally change to wchar without too much
fuss (maybe).
libr supplies an __obj_forward definition that links to a builtin, but
as it is the only def in its object file, it is readily replaceable by
an alternative Ruamoko implementation.
The builtin version currently simply errors out (rather facetiously),
but only as a stub to allow progs to load.
Other than its blocking of access to certain files, it really wasn't
that useful compared to the functions in qfs, and pointless with access
to qfs anyway.
Only as scalars, I still need to think about what to do for vectors and
quaternions due to param size issues. Also, doubles are not yet
guaranteed to be correctly aligned.
Empty structs are now (correctly) invalid. The hack of using an empty
struct to represent a handle returned from a builtin has been unnecessary
since opaque structs were implemented: now a pointer to an opaque struct
can be used. This is mostly safe as handles are aways negative and thus
attempting to dereference such a pointer should result in a VM error. It
will be even safer once const is implemented and the pointers can be made
constant (eg, typedef struct handle * const handle;)
