This allows the likes of:
qfv_pushconstantrangeinfo_s = {
.name = qfv_pushconstantrangeinfo_t;
.type = (QFDictionary);
.dictionary = {
.parse = {
type = (labeledarray, qfv_pushconstantinfo_t, name);
size = num_pushconstants;
values = pushconstants;
};
stageFlags = $name.auto;
};
stageFlags = auto;
};
Leading to:
pushConstants = {
vertex = { Model = mat4; blend = float; };
fragment = { colors = uint; base_color = vec4; fog = vec4; };
};
Where the label of the labeled array (which pushConstants is) is
actually an enum flag and the dictionary value is another labeled array.
It turns out labeled arrays don't work if structs aren't declared in the
right order (no idea what that is, though) as the struct might not have
been processed when the labeled array field is initialized. Thus, do a
pro-processing pass to set up any parse data prior to writing the
tables.
This treats dictionary items as arrays ordered by key creation (ie, the
order of the key/value pairs in the dictionary is preserved). The label
is written to the specified field when parsing the struct. Both actual
arrays and single element "arrays" are supported.
The real reason for the delay in implementing support for pNext is I
didn't know how to approach it at the time, but with the experience I've
gained using and modifying vkparse, the solution turned out to be fairly
simple. This allows for the use of various extensions (eg, multiview,
which was used for testing, though none of the hookup is in this
commit). No checking is done on the struct type being valid other than
it must be of a chainable type (ie, have its own pNext).
Dependencies on vkparse.hinc were spreading through the code which I
didn't want as that removes a lot of the automation from the automake
files. This keeps all parser code internal to vkparse.c's scope, and any
accesses required for enum and struct (not yet) definitions can be
fetched by name.
The property list specifies the base structures for which parser code
will be generated (along with any structures and enums upon which those
structures depend). It also defines option specialized parsers for
better control.
It worked as a proof of concept, but as the code itself needs to be a
bit smarter, it would be a lot smarter to break up that code to make it
easier to work on the individual parts.
