2025-01-07Add backtraces to examples (#5973)Anders Leino
* examples: Log stack trace on exceptions For now, this is only implemented on Windows. This helps to address #5520. * examples: Print log file if there is any * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He <yonghe@outlook.com>
2025-01-07Add example showing how to use Slang/WASM (#5996)Anders Leino
This closes #5656.
2025-01-07Fix some robustness issues in the examples (#5984)Anders Leino
* examples: Make hello-world example exit gracefully if VK cannot be initialized - Check if VK API function pointers are valid before using them - Return 0 and exit if VK initialization fails - Enable hello-world example * examples: Fixes for ray-tracing examples - Assert that accelleration structure buffer is not nullptr - Check if buffer creation succeeded before proceeding - This makes initialization not hang, but it still fails. Therefore, the test expectations are just updated to point to another issue. - Enable ray-tracing tests on Windows

2024-12-18Add slang example tests to CI (#5879)Anders Leino
* Examples: Don't proceed if 'initializeBase' fails * Examples: Only access gWindow if it's been initialized * Examples: Free memory from CommandLineToArgvW * Add example run step to CI Lots of examples are still unexpectedly failing, but is one small step towards addressing issue #5520.
2024-12-12Add an example for using the reflection API (#5839)Theresa Foley
* Add an example for using the reflection API The example program is meant to accompany a document that goes into more detail about the mental model behind the reflection API and the way this program drives it. Ideally this program can land before the document goes live, and then the document can be published with a link to the example. After that, the example could be updated to include links into the live document. Along with adding the example program, this change also adds some convenience functions to the reflection API to avoid cases where the program would otherwise need to cast between `slang::ParameterCategory` and `SlangParameterCategory`. * format code * fixup: error noticed by clang --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>

2024-11-13Correct include dir for libslang (#5539)Ellie Hermaszewska
This stops adding the repo root to the include path for anything linking with slang. This enabled a bunch of convenient includes, but might lead to confusing behavior for anyone including slang. Not to mention differences including it from an install vs source. Co-authored-by: Yong He <yonghe@outlook.com>

2024-11-01Improve on spirv generation compile option (#5479)kaizhangNV
CompilerOptionName::EmitSpirvViaGLSL and CompilerOptionName::EmitSpirvDirectly options are not mutually exclusive, but due to compatible reason, we cannot delete those options. Instead, this change makes the effort to create a new option name EmitSpirvMethod, and we will turn those two options into the new one internally. Also, we put a priority implicitly on those two options, where EmitSpirvDirectly always win if it's set. We have another location that can setup the same option, where is through SlangTargetFlags::SLANG_TARGET_FLAG_GENERATE_SPIRV_DIRECTLY. We should definitely deprecate this flag to avoid more confusing. But for the same compatible reason, we cannot do that in this PR. Again, we will encourage people to not use this flag, but using the CompilerOptionName instead. In this PR, we will also implicitly give CompilerOptionName higher priority, it means that as long as user setup the CompilerOptionName for emit spirv method, it always take higher priority for the final decision.

2024-10-15 Move C interface from slang.h to slang-deprecated.h (#5301)Ellie Hermaszewska
* Squash redundant move warnings * Move C interface from slang.h to slang-deprecated.h spGetBuildTagString remains, because it's useful to have before the global session exists. This C API is used quite pervasively in the C++ helpers (for example slang::UserAttribute. It's not trivial to move these to slang-deprecated.h as they're entangled with some enums which are themselves used elsewhere in the compiler. The fact that these helpers use the C API can be viewed as an implementation detail for now, and this usage moved to slang-deprecated in due course. Closes https://github.com/shader-slang/slang/issues/4758 * Squash warnings for our usage of our deprecated API --------- Co-authored-by: Yong He <yonghe@outlook.com>
2024-08-30capture component type (#4967)kaizhangNV
* Refactor the IComponentType recording Refactor the `IComponentType` recording by creating a abstract class `IComponentTypeRecorder` to record all the methods of `IComponentType`, so that `ICompositeComponentType`, `IModule`, 'IEntryPoint', 'ITypeConformance' can share the same recording implementation. Capture the out IComponentType from linkWithOptions() link() specialize() renameEntryPoint() * fix bugs * Finish the unimeplemented functions in json consumer Fix the address print to use 64 bit hex. Fix the reference count issue when allocating new recorder object. * Disable few examples using reflection APIs * Add gpu-printing example into slang-test * Replace of using std::unique_ptr with RefPtr
2024-08-28Migrate 3 more examples to slang-unit-test (#4927)kaizhangNV
* Convert 'ray-tracing-pipeline' example into slang-test * Convert model-view and 'autodiff-texture' examples to slang-test * Add more error message in RecordReplay test * Fix a shader issue in autodiff-texture
2024-08-27Migrate examples (#4920)kaizhangNV
* Migrate cpu-hello-world to new slang API Migrate cpu-hello-world to new slang API, and also convert this example as one of the unit test. * Add 'shader-object' to slang-unit-test * Convert ray-tracing example into unit-test Convert ray-tracing example into unit-test * Fix some replay bugs: - Wrong decode type in 'getEntryPointHostCallable'. - Mistakes in computing the output buffer size. - Wrong decode type in array size in specialize() call. - When capture entrypoint, we should increase the reference count for the allocated entrypoint recorder object, because that is allocated by record layer, it should be owned by the layer, user should not be able to free it. - Improve json consumer on the prelude text. * Test verify change: In our test, we add a "callIdx" string at beginning of the hash-code string, as there could be more than one modules in the example, so they could call 'getEntryPointHash' multiple times, in order for the test can identify them, add "callIdx: <number>" as the key word.
2024-08-26Feature/record unit test (#4910)kaizhangNV
* Fix the slang-test bug Since we reorganize the build directory, now the libraries are located at different directory with executables in non-Windows platform, we have to change the code on how to find the dll directory. * Integrate the record/replay test into slang-unit-test We create a unit-test-record-replay.cpp to run the converted slang examples in child process as our tests for the record-replay layer. * Disable the test on Apple Due to the limitation of current examples, we temporarily disable them on apples. Change the ci to make this test only be run on the gpu-equipped runners, for other runners we add a white-list file "expected-failure-record-replay-tests.txt". * Remove 'hello-world' example from unit test "hello-world" doesn't use gfx abstract library, instead it uses vk directly, it's not a preferable way. So we will drop this test, instead, we will use cpu-hello-world example.
2024-08-22Feature/capture unit test (#4898)kaizhangNV
* record/replay: Add tests Modify the hello-world example to generate the hash code for the entry point spirv code, so that we can compare it with replaying the example. Add the test script to run the example and compare the hash code with replaying it. * Check nullptr for out Diagnostics We need to check whether the output Diagnostics is a nullptr, because it's allowed. * Fix the double free pointers * Add triangle example as the new test for record-replay Change the example base to add the offline rendering path because we don't want to display anything when we're in the test mode. This change involves introducing a TestBase that will parse the command line option. It will decide whether we are in the test mode. Disable all the swapchain and windows related creation, instead we will only create one single framebuffer for the render target. * Address comments TODO: In the follow up patches, I will add more tests and integrate the test flow into slang-unit-test.
2024-07-17Move the file public header files to `include` dir (#4636)kaizhangNV
* Move the file public header files to `include` dir Close the issue (#4635). Move the following headers files to a `include` dir located at root dir of slang repo: slang-com-helper.h -> include/slang-com-helper.h slang-com-ptr.h -> include/slang-com-ptr.h slang-gfx.h -> include/slang-gfx.h slang.h -> include/slang.h Change cmake/SlangTarget.cmake to add include path to every target, and change the source file to use "#include <slang.h>" to include the public headers. The source code update is by the script like follow: ``` fileNames_slang=$(grep -r "\".*slang\.h\"" source/ -l) for fileName in "${fileNames_slang[@]}" do echo "$fileName" sed -i "s/\".*slang\.h\"/\"slang\.h\"/" $fileName done ``` * Fix the test issues * Fix cpu test issues by adding include seach path * Update cmake to not add include path for every target Also change "#include <slang.h>" to "include "slang.h" " to make the coding style consistent with other slang code. * Change public include to private include for unit-test and slang-glslang

2024-06-06Fixed profile string per request in pr#4268 (#4297)Hai Nguyen
Changed profile string from glsl_440 to spirv_1_5 per request in pr#4268.
2024-06-04Fixes incorrect profile string (#4268)Hai Nguyen
This CL fixes a typo in the profile string for the hello-world example. Currently "glsl440" is passed into findProfile() resulting in a return value of SLANG_UNKNOWN_PROFILE since format of the profile name is incorrect. The correct profile name is glsl_440, therefore the string passed into findProfile() should be "glsl_440".

2022-02-03Fixed naming conflicts in heterogeneous-hello-world (#2114)David Siher
* Fixed naming conflicts in heterogeneous-hello-world Added 3 new modifiers (`__unmangled`, `__exportDirectly`, `__externLib`) `__unmangled` causes mangleName() to return the normal name of the decl. `__exportDirectly` changes parent decl name concatenation behavior to use "::" instead of "." (for Name Hint) and emits the name hint when it exists, otherwise it emits the mangled name. `__externLib` stops Slang from emitting the corresponding struct. Also made necessary changes to heterogeneous-hello-world so that this new functionality is shown off. * Undo unintentional formatting changes Co-authored-by: Yong He <yonghe@outlook.com>
