[thewtex]

Agenda

• Review slides from @henryiii.
• Round table

Attending

• Matt McCormick
• Henry Scheiner
• Jean-Christophe Fillion-Robin

Discussion

• A few updates, a lot of progress, new projects were adopted at the SciPy conference
• itk-5.4rc1 built with latest scikit-build classic now

Slides review notes

• Continue to improve cross-compling support
  • FindPython does not support cross-compiling very well yet
• CMake component support in progress
  • supply components in pyproject.yaml
  • build targets
    • multiple
    • cmake --build
• sdist normalization
  • always lower case, underscores in sdist filename output
• dynamic-metadata
  • now a package (at SciPy conf)
  • redesign targetted for 0.5
  • regex plugin for extracting metadata like hatch
  • develop a plugin as an example to get the package version from the CMake cache?
  • minimum version plugin
  • generate package dependencies during build
    • need to update packaging standards so we can have static + additional dynamic dependencies
  • hacking build-system.requires, dynamic-metadata packages to add wheels to bring in
    • build-time sdks
    • utility cmake modules
      • relevant test: https://github.com/scikit-build/scikit-build-core/tree/main/tests/packages/custom_cmake
• Python 2.7 support
  • Will be able to use the wheel
  • Be able to build the wheel?
• CPython Cross-compiling for scikit-build, meson-python
• Slides from SciPy Projects Tools Updates

Recording and Transcript

• NA

Example for dynamic-metadata configuration with plugin dependencies

[build-system]
requires = ["scikit-build-core", "setuptools-scm", "dynamic-metadata-regex"]

[project]
dynamic = ["version", "description", "dependencies"]

dependencies = ["numpy"]

[tool.dynamic-metadata]
version.provider = "setuptools_scm"
description.provider = "dynamic_metadata_regex"
description.regex = "(*.)"

• Having multiple line in a table is only supported in toml 2.1 and above

description = {
    provider = "dynamic_metadata_regex",
    regex = "(*.)"
}
