Detailed Description

This script writes the full path to the MacSDK that is being used
by the clang_mac toolchain for builds within this workspace. This
path is created by //toolchain/download_mac_toolchain.bzl when
downloading the mac toolchain, and the MacSDK directory is populated
with symlinks to XCode's MacSDK contents.

◆ GetBazelOutputDir()

str tools.macsdk_dir.GetBazelOutputDir ( )

Return the Bazel output directory.

This is described in https://bazel.build/remote/output-directories

Definition at line 50 of file macsdk_dir.py.

    """Return the Bazel output directory.
 
    This is described in https://bazel.build/remote/output-directories"""

    # three levels returns the output directory.

◆ GetBazelRepositoryCacheDir()

str tools.macsdk_dir.GetBazelRepositoryCacheDir ( )

Return the Bazel repository cache directory.

◆ GetBazelWorkspaceCacheDir()

str tools.macsdk_dir.GetBazelWorkspaceCacheDir ( )

Determine the output directory cache for this workspace.

Note: The Bazel docs(1) are very clear that the organization of the output
directory may change at any time.

◆ GetBazelWorkspaceHash()

str tools.macsdk_dir.GetBazelWorkspaceHash ( )

Return the Bazel hash for this workspace.

This is the MD5 has of the full path to the workspace. See
https://bazel.build/remote/output-directories#layout-diagram for more detail.

◆ GetMacSDKSymlinkDir()

str tools.macsdk_dir.GetMacSDKSymlinkDir ( )

Determine the MacSDK symlinks directory for this workspace.

◆ GetWorkspaceDir()

str tools.macsdk_dir.GetWorkspaceDir ( )

Return the workspace directory containing this script.
