2025-04-07Return non-escaped strings from user-defined attributes (#6735)aidanfnv
Fixes #6624 This commit changes the behavior of getArgumentValueString() to return the string's value, instead of returning the string's token, as that token also contains the surrounding quotation marks. This commit also modifies the relevant unit test accordingly, to not check for the surrounding quotations.

2025-02-26expose value of constant integers in module reflection (#6367)Alexandre Bléron
* Expose value of constant integers in module reflection This commit adds `VariableReflection::getDefaultValueInt` to get the value of a variable if it is a compile-time constant integer. TODO: currently it works only if the initializer expression is an integer literal, references to other constant values are not handled. * Update VarDecl folded constant value during DeclBodyVisitor Constant folding for integer values is already done internally by _validateCircularVarDefinition, this just reuses the result. * Address review comments & formatting * Formatting --------- Co-authored-by: Yong He <yonghe@outlook.com>

2024-08-27Add ability to specialize generic references to functions, types and more ↵Sai Praveen Bangaru
(#4909) * More reflection API features. + Lookup methods and members (by string) on types + Fix issue with looking up non-static members through the scope operator '::' + `GenericReflection`: Cast a decl to generic to access unspecialized generic parameter names and constraints + `GenericReflection`: Use `getGenericContainer()` from function, variable or type to access the 'nearest' generic parent along with specialization info + `GenericReflection::getConcreteType` and `GenericReflection::getConcreteIntVal`: to get the concrete type of a param in the context of the reflection object + `GenericReflection::getOuterGenericContainer` to go up one level and get the outer generic declarations (if there are more than one enclosing generic scopes) + `DeclReflection::getParent`: go to parent declaration. + Change `VariableReflection` to be a `DeclRef` rather than a decl (allows us to return properly substituted types for methods, members, and more) * Fix Falcor issue * Initial namespace reflection support * FIx issue with specializing witness tables * Add API method for specializing parameters of a generic decl * Add ability to specialize generic references to functions, types and more This PR adds the following end-points: - `specializeGeneric()` method that can be called on a generic reflection to substitute arguments for generic type and value parameters. It returns another generic reflection, but this time with the appropriate substitution. - `applySpecializations()` method to then copy these specializations onto an existing type or function reflection. - `isSubType()` to check if a type is a subtype of another type (useful to check if a type is differentiable by checking `IDifferentiable`) This PR also: - Adds `DeclReflection::Kind::Namespace` so that namespace containers are correctly reflected when walking the decl-tree. the name can be obtained through `getName()` but there's no need to cast to a namespace (since there's nothing else we can do with a namespace decl) - Fixes an issue with name-based lookups that fail if a type or function is referenced without specializations. Its helpful to be able to form a reference to a function with default substitutions, so that we can we can specialize it later (either directly, or via argument types). * Update slang.h * Fix up naming * Update slang-compiler.h * Update slang-reflection-api.cpp * Update slang.cpp * Update slang.cpp * Update slang.cpp * Use `checkGenericAppWithCheckedArgs` to do specialization * Update slang-reflection-api.cpp * Update slang-check-decl.cpp

2024-07-18Initial implementation for decl-tree reflection API (#4666)Sai Praveen Bangaru
* Initial implementation for decl-tree reflection API This patch adds Slang API methods for walking all the declarations in the AST. We expose this functionality through an abstract `DeclReflection` class that can be a type, function or a variable declaration. We also provide ways to cast the decl to a `FunctionReflection`, `TypeReflection` or `VariableReflection` and traverse through the child nodes (for instance, a struct type will have component variable declarations) This patch also adds `ISlangInternal` as an internal COM interface to allow us to cast IGlobalSession to the internal Session pointer while bypassing any wrappers (such as the capture interface) * Update slang.h * Remove `ISlangInternal` (its causing a diamond pattern w.r.t `ISlangUnknown`) and use `ComPtr` for proper ref management. * Update unit-test-decl-tree-reflection.cpp * Change `FunctionDeclBase` to use `DeclRef` instead of directly using the decl. * Update slang-reflection-api.cpp
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
2024-07-10Add reflection API for functions. (#4587)Yong He
* Add reflection API for functions. This change adds `SlangFunctionReflection` type in the reflection API that provides methods for querying function result type, parameters and user-defined attributes. `ProgramLayout::findFunctionByName` can now find a function with the given name and returns a `FunctionReflection`. `IEntryPoint` now has a `getFunctionReflection` method that returns an `FunctionReflection` for the entrypoint. * More modifiers; make reflection API consistent.

2024-03-13Implement glsl atomic's [non image or memory scope] with optional ↵ArielG-NV
extension(s); resolves #3587 for GLSL & SPIR-V targets (#3755) The following commit implements atomic operations & types associated with OpenGL 4.6, GL_EXT_vulkan_glsl_relaxed, GLSL_EXT_shader_atomic_float, GLSL_EXT_shader_atomic_float2, for GLSL & SPIR-V targets. Fully implements all functions, and built-in type's, resolves https://github.com/shader-slang/slang/issues/3560 for GLSL & SPRI-V targets. [Atomic extensions for GLSL can be found here](https://github.com/KhronosGroup/GLSL/tree/main) Notes of worth: * atomic_uint is well defined in GLSL->OpenGL, although was removed in GLSL->VK unless a compiler extension is supported (GL_EXT_vulkan_glsl_relaxed). This support entails transforming all atomic_uint operations and references into a storage buffer. SPIR-V has AtomicCounter+AtomicStorage (atomic_uint parallel) but does not implement these capabilities for SPIR-V->VK in any scenario. Due to the case we transform atomic_uint ourselves (GLSL_Syntax->Slang_IR) to accommodate transforming atomic_uint into valid syntax. * GLSL_EXT_shader_atomic_float2 (all float16_t & some float/double operations) support is minimal and worth watching out for if enabling the tests.
