Numbast 0.5.1 (Aug 2025)

  • Use cuda vended typing templates (#173)

Numbast 0.5.0 (Aug 2025)

Numbast 0.5.0 focuses on build-system integration and cleanup, simplifies dependencies, and adds configurability across static binding generation and parsing. Highlights include removing RAPIDS and pynvjitlink requirements, adopting GNU extension parsing, new typing/target registry hooks, expanded config options (skip/prefix rules, GPU arch, module setup/teardown callbacks), clearer error surfacing, and numerous fixes and CI improvements.

Improvements

  • bump to version 0.5.0
  • Explicitly Pass Cmake Config Options to cmake Command in Build Script (#169)
  • remove dependency on RAPIDS conda channels (#167)
  • Completely Remove Pynvjitlink Requirements (#159)
  • Use GNU Extension Standard for Default Clang Parse (#165)
  • Allow creation of custom typing/target registry (#161)
  • Exclude typedefs for excluded structs (#160)
  • Support "Skip Prefix" in numbast config (#156)
  • Allow Numbast to Parse Bfloat16 (#155)
  • Explicitly Raise ClangAST Parsing Error (#150)
  • Remove Unused CI Files (#157)
  • Integration to build-tools PR 2 (#154)
  • Configure static binding CC via GPU Arch Entry (#152)
  • Integration PR as part of Build Systems (#149)
  • Add Config Item to Allow Module Setup/Teardown Callback Functions (#148)
  • fix benchmarks, add missing tests from CI (#147)
  • Fix a Bug where GlobalDecl is constructed mistakenly when performing name mangles (#146)
  • Add Prefix Remover for Functions in Static Binding Generator (#144)
  • Fix CI (#145)

Numbast 0.4.0 (Jun 2025)

Improvements

  • Use function mangled name to deduplicate forward declared function decls (#142)
  • Use Itanium Name Mangler to resolve shim function name conflicts (#139)
  • Alter cooperative launch list to regex list (#136)
  • Refactor _static_binding_generator with Config Input (#135)
  • Get contributing section from numba-cuda on making a new release (#134)
  • Add config for functions that requires cooperative launch (#133)
  • Update Dependency List, Optional run Ruff (#131)
  • Explicitly expose symbols via __all__ (#129)
  • Fix the numbast_extension install instruction (#132)
  • Allow Custom Binding Name Specified via YAML (#128)
  • Add CTPSD matcher, WAR nested RecordDecl (#126)
  • Add ConstExpr Vardecl Matcher to Extract ConstExpr Value from VarDecl (#112)
  • Use Single Upload Job for CondaBuild (#124)
  • Build Against Clang20 (#125)

Numbast 0.3.0 (May 2025)

Numbast version 0.3.0 delivers the bfloat16 static bindings to Numba-CUDA. Multiple improvements on the repository made this delivery possible.

Improvements

The majority of the change is centralized in #106

  • The linkable code object that contains the shim functions are added to active_linking_library in python. Streamed Shim Function Writes. The shim functions are written to a string stream at lowering time using a special class named KeyedStringIO that prevents double write of the same shim function.
  • Ruff formatting generated code (with import sort): Add Ruff Linter run to generated bindings
  • Generation metadata added to binding: Add Information to Make Binding Generation More Reproducible
  • Allow user to specify entry point and retain file list in config file using relative path d1e7aa2
  • Allow user to add additional imports via Additional Import config item 8f7bd22
  • Allow user to override the include line in shim function via Shim Include Override config item 8f7bd22
  • Allow user to specify whether to include check in the binding to assert existence of pynvjitlink bad0c69
  • Allow user to specify a custom macro, which dictates both how clangTooling parses the header file, as well as how the shim function is compiled with NVRTC. 0f0ee9c

Dependency Changes

  • Depends on numba-cuda >=0.10.0
  • Pins to clangdev ==18

Numbast 0.2.0 (Nov 2024)

New Features

  • Numbast now requires cuda-version >=12.5

Numbast 0.1.0 (Feb 28 2024)

New Features
