github.com/pekim/go-skia is a package that provides generated Go bindings for some of skia's C++ api.

To add it to a Go module, go get github.com/pekim/go-skia.

go-skia is licensed under the terms of the MIT license.

go-skia has been developed on linux amd64. Libraries for darwin amd64 and arm64 are included and it may work on macOS, but it's untested.

• version 1.23.0 or later of Go
• version 15 or later of clang

The build script does the following

• rust-skia repo
  • clone repo (if not present) to _skia dir
  • check out desired tag (if not currently checked out)
  • copy required header files to skia dir
• skia-binaries repo
  • if desired release not present in lib dir
    • download releases for platforms
    • extract the platform releases in to lib dir
• generate Go bindings
• run tests to verify that the generated bindings result in a package that builds

./build.sh

To upgrade skia, update some variables in build.sh.

• https://github.com/rust-skia/skia/tags
  • SKIA_TAG - set to a tag, such as m136-0.84.2
• https://github.com/rust-skia/skia-binaries/releases
  • Expand the assets for the latest available minor release that SKIA_TAG references. For example if SKIA_TAG is m136-0.84.2, the release to use will be 0.84.0. Do not try to mix minor releases, as it's unlikely to work.
  • SKIA_BINARIES_COMMITHASH - set to the hash used in all of the release's downloadable assets
  • SKIA_BINARIES_TAG - the release's tag, such as 0.84.0

The leading underscore in the dir name is to prevent the directory appearing in godoc output in the "Subdirectories" section.

There are configuration files for linting and other checks. To use a git pre-commit hook for the checks
