IN_UpdateAxis (for nice handling of axis updates, especially relative
motion for mice) and IN_Binding_HandleEvent because registering an event
handler blocks qwaq's internall call to IN_Binding_HandleEvent.
It was a right cow to get working at all due to the tangled mess of
dependencies between different hierarchies (switching to hierarchies as
components helpt), but other that some vertical positioning (paragraphs
and descenders), it's working fairly well now (and fairly quick other
than I think I need to ensure the shaping cache is used).
This is for scroll boxes (the nesting of canvases is for the clipping
they provide). There are some issues with automatic layout, but this
gets things mostly working, in particular the management of the link
between hierarchies as a canvas is always the root of its hierarchy.
sincos is just a wrapper around the GNU libc sincos. sincosh is the
equivalent for sinh and cosh, but there doesn't seem to be any such
function, so it's just the two wrapped. They both return their results
in a vec2/vec2d as (sih[h], cos[h]).
Wrap the strtod, strtof, strtol, strtoul functions, supporting the end
pointer as well (if not nil, the int offset of the end pointer relative
to the string start is returned).
Also, str_unmutable creates a return string from a mutable string
(copying it).
Meaning some leaks have been plugged, and some useful functions added:
loading a file (avoids polluting progs memory), setting the single
character lexeme string, and getting the line number.
I never liked the various hacks I had come up with for representing
resource handles in Ruamoko. Structs with an int were awkward to test,
pointers and ints could be modified, etc etc. The new @handle keyword (@
used to keep handle free for use) works just like struct, union and
enum in syntax, but creates an opaque type suitable for a 32-bit handle.
The backing type is a function so v6 progs can use it without (all the
necessary opcodes exist) and no modifications were needed for
type-checking in binary expressions, but only assignment and comparisons
are supported, and (of course) nil. Tested using cbuf_t and QFile: seems
to work as desired.
I had considered 64-bit handles, but really, if more than 4G resource
objects are needed, I'm not sure QF can handle the game. However, that
limit is per resource manager, not total.
qfot_basic_t is necessary for getting at the width of basic value types
(int, uint, float, long, ulong, double) in order to distinguish between
scalars and vectors of those types.
I had forgotten this when doing the Ruamoko VM and qfcc changes.
The software renderer uses Bresenham's line slice algorithm as presented
by Michael Abrash in his Graphics Programming Black Book Special Edition
with the serial numbers filed off (as such, more just so *I* can read
the code easily), along with the Chen-Sutherland line clipping
algorithm. The other renderers were more or less trivial in comparison.
And other related fields so integer is now int (and uinteger is uint). I
really don't know why I went with integer in the first place, but this
will make using macros easier for dealing with types.
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.
