This is most useful when parsing a labeled array where the key/value
pairs go into a simple array:
key = value;
going to:
struct foo {
const char *key;
enumtype value;
};
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.
This allows having sections in a spec used for things like `properties`
that have no corresponding fields in the actual struct: the field is
ignored when parsing and no cexpr field symbol is emitted.
There's still a lot of work to do, but the basics are in. The spec will
be parsed into info structs that can then be further processed to
generate all the actual structs, generally making things a little less
timing dependent (eg, image view info refers to its image by name).
The new render pass and subpass structs have their names mangled for now
until I can switch over to the new system.
Ruamoko currently doesn't support `const`, so that's not relevant, but
recognizing `char *` (via a hack to work around what looks like a bug
with type aliasing) allows strings to be handled without having to use a
custom parser. Things are still a little clunky for custom parsers, but
this seems to be a good start.
Using the typedef name makes using structs declared as
typedef struct foo_s { ... } foo_t;
easier and cleaner. Sure, I could have written the "struct foo_s" for
the output name, but I'm much more likely to look for foo_t than foo_s
when checking the generated code.
It now lives in vulkan_renderpass.c and takes most of its parameters
from plist configs (just the name (which is used to find the config),
output spec, and draw function from C). Even the debug colors and names
are taken from the config.
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).
This allows for easy (and safe) printing of cexpr values where the type
supports it. Types that don't support printing would be due to being too
complex or possibly write-only (eg, password strings, when strings are
supported directly).
It simply parses the referenced plist dictionary (via @inherit =
plist.path;) into the current data block, then allows the data to be
overwritten by the current plist dictionary. This may be a bit iffy for
any allocated resources, so some care must be taken, but it seems to
work nicely.
long is ignored for double, and v6p progs are stuck with 32 bits for
longs (don't feel like extending v6p any further), but the basics are
there for Ruamoko.
short is ignored for ints because the minimum size is 32, and signed is
just noise for ints anyway (and no chars, so...).
unsigned, however, is finally implemented properly (or at least seems to
be working correctly: tests pass after getting things compiling again,
and lt.u is used where it should be :)
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.
Forgetting to invoke [super dealloc] in a derived class's -dealloc
method has caused me to waste far too much time chasing down the
resulting memory leaks and crashes. This is actually the main focus of
issue #24, but I want to take care of multiple paths before I consider
the issue to be done.
However, as a bonus, four cases were found :)
I want to support reading VkPhysicalDeviceLimits but it has some arrays.
While I don't need to parse them (VkPhysicalDeviceLimits should be
treated as read-only), I do need to be able to access them in property
list expressions, and vkgen generates the cexpr type descriptors too.
However, I will probably want to parse arrays some time in the future.
This ensures that unused parser blocks do not get emitted. In the
testing of the upcoming support for fixed arrays, the blend color
constants were being double emitted (both as custom and normal parser)
due to being an array. gcc did not like that (what with all those
warning flags).
Well... it could be done better, but this works for now assuming it's in
/usr/include (and it's correct for mxe builts). Does need proper
autoconfiscation, though.
The static libs are used to build the plugins, but make it easy to use
only those modules needed for tests. Fixes the link error when running
"make check" with non-static plugins.
It's not entirely there yet, but the basics are working. Work is still
needed for avoiding duplication of objects (different threads will have
different contexts and thus different tables, so necessary per-thread
duplication should not become a problem) and general access to arbitrary
fields (mostly just parsing the strings)
The prototypes for handle parsers needed to be changes because it turned
out "single" was inappropriate for handles as "single" allocates memory
for the parsed object, but handles must be written directly.
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.
Array and single type overrides now allow the parsing of the items
themselves to be customized. This makes it easy to handle arrays and
pointers to single items while also using custom specifications, rather
than relying entirely on the custom override.
