The make and CMake build flavors offer the option to treat exceptions as assertions. To disable exceptions for make just append `SPIRV_CROSS_EXCEPTIONS_TO_ASSERTIONS=1` to the command line. For CMake append `-DSPIRV_CROSS_EXCEPTIONS_TO_ASSERTIONS=ON`. By default exceptions are enabled.
### Static, shared and CLI
You can use `-DSPIRV_CROSS_STATIC=ON/OFF` `-DSPIRV_CROSS_SHARED=ON/OFF` `-DSPIRV_CROSS_CLI=ON/OFF` to control which modules are built (and installed).
## Usage
### Using the C++ API
For more in-depth documentation than what's provided in this README, please have a look at the [Wiki](https://github.com/KhronosGroup/SPIRV-Cross/wiki).
The C++ API is the main API for SPIRV-Cross. For more in-depth documentation than what's provided in this README,
please have a look at the [Wiki](https://github.com/KhronosGroup/SPIRV-Cross/wiki).
**NOTE**: This API is not guaranteed to be ABI-stable, and it is highly recommended to link against this API statically.
The API is generally quite stable, but it can change over time, see the C API for more stability.
To perform reflection and convert to other shader languages you can use the SPIRV-Cross API.
For example:
@ -99,19 +106,143 @@ int main()
}
```
### Using the C API wrapper
To facilitate C compatibility and compatibility with foreign programming languages, a C89-compatible API wrapper is provided. Unlike the C++ API,
the goal of this wrapper is to be fully stable, both API and ABI-wise.
This is the only interface which is supported when building SPIRV-Cross as a shared library.
An important point of the wrapper is that all memory allocations are contained in the `spvc_context`.
This simplifies the use of the API greatly. However, you should destroy the context as soon as reasonable,
or use `spvc_context_release_allocations()` if you intend to reuse the `spvc_context` object again soon.
Most functions return a `spvc_result`, where `SPVC_SUCCESS` is the only success code.
For brevity, the code below does not do any error checking.
```c
#include <spirv_cross_c.h>
const SpvId *spirv = get_spirv_data();
size_t word_count = get_spirv_word_count();
spvc_context context = NULL;
spvc_parsed_ir ir = NULL;
spvc_compiler compiler_glsl = NULL;
spvc_compiler_options options = NULL;
spvc_resources resources = NULL;
const spvc_reflected_resource *list = NULL;
const char *result = NULL;
size_t count;
size_t i;
// Create context.
spvc_context_create(&context);
// Set debug callback.
spvc_context_set_error_callback(context, error_callback, userdata);
// Parse the SPIR-V.
spvc_context_parse_spirv(context, spirv, word_count, &ir);
// Hand it off to a compiler instance and give it ownership of the IR.
spvc_context_create_compiler(context, SPVC_BACKEND_GLSL, ir, SPVC_CAPTURE_MODE_TAKE_OWNERSHIP, &compiler_glsl);
// Do some basic reflection.
spvc_compiler_create_shader_resources(compiler_glsl, &resources);
spvc_resources_get_resource_list_for_type(resources, SPVC_RESOURCE_TYPE_UNIFORM_BUFFER, &list, &count);

list[i].name);

### Linking
#### CMake add_subdirectory()
This is the recommended way if you are using CMake and want to link against SPIRV-Cross statically.
#### Integrating SPIRV-Cross in a custom build system
To add SPIRV-Cross to your own codebase, just copy the source and header files from root directory
and build the relevant .cpp files you need. Make sure to build with C++11 support, e.g. `-std=c++11` in GCC and Clang.
Alternatively, the Makefile generates a libspirv-cross.a static library during build that can be linked in.
### Creating a SPIR-V file from GLSL with glslang
#### Linking against SPIRV-Cross as a system library
It is possible to link against SPIRV-Cross when it is installed as a system library,
which would be mostly relevant for Unix-like platforms.
##### pkg-config
For Unix-based systems, a pkg-config is installed for the C API, e.g.:
```
$ pkg-config spirv-cross-c-shared --libs --cflags
-I/usr/local/include/spirv_cross -L/usr/local/lib -lspirv-cross-c-shared
```
##### CMake
If the project is installed, it can be found with `find_package()`, e.g.:
```
cmake_minimum_required(VERSION 3.5)
set(CMAKE_C_STANDARD 99)
project(Test LANGUAGES C)
find_package(spirv_cross_c_shared)
if (spirv_cross_c_shared_FOUND)
message(STATUS "Found SPIRV-Cross C API! :)")
else()
message(STATUS "Could not find SPIRV-Cross C API! :(")
endif()
add_executable(test test.c)
target_link_libraries(test spirv-cross-c-shared)
```
test.c:
```c
#include <spirv_cross_c.h>
int main(void)
{
spvc_context context;
spvc_context_create(&context);
spvc_context_destroy(context);
}
```
### CLI
The CLI is suitable for basic cross-compilation tasks, but it cannot support the full flexibility that the API can.
Some examples below.
#### Creating a SPIR-V file from GLSL with glslang
```
glslangValidator -H -V -o test.spv test.frag
```

### Testing
SPIRV-Cross maintains a test suite of shaders with reference output of how the output looks after going through a roundtrip through
glslangValidator then back through SPIRV-Cross again. The reference files are stored inside the repository in order to be able to track regressions.

When adding support for new features to SPIRV-Cross, a new shader and reference file should be added which covers usage of the new shader features in question.
Travis CI runs the test suite with the CMake, by running `ctest`. This method is compatible with MSVC.
### Licensing
Contributors of new files should add a copyright header at the top of every new source code file with their copyright

## ABI concerns
### SPIR-V headers
The current repository uses the latest SPIR-V and GLSL.std.450 headers.
SPIR-V files created from older headers could have ABI issues.
## Regression testing
In shaders/ a collection of shaders are maintained for purposes of regression testing.
