# Configuration for CCCL project change detection.
# Projects are declared in this file along with their human-friendly names, path
# matching patterns, and dependency relationships. Every path pattern is
# evaluated as a regular expression anchored to the repository root.
#
# Changed files that satisfy a project's include_regexes, exclude_regexes, and
# exclude_project_files checks will mark that project as "dirty". The current project
# will be added to the FULL_BUILD if it has dirty files or if any of its
# full_dependencies are dirty.
#
# Additionally, if any of a project's lite_dependencies are dirty, the current project
# will be added to the LITE_BUILD.
#
# If any transitive dependencies are dirty (eg. a full or lite dependency has
# dirty dependencies of its own), the current project will also be added to the LITE_BUILD.
#
# Projects with large dependency trees are split into "public" and "internal" sub-projects.
# The "public" sub-project contains only the public API files, while the "internal"
# sub-project contains tests, examples, and other non-public files. This allows changes to
# internal files to avoid triggering rebuilds of dependent projects when the public API
# is not changed.
#
# Layout:
#   project_key:          mapping from project key to configuration
#     name:               display name used in logs/reports
#     matrix_project:     project name to use for matrix generation. If not provided,
#                           the project is considered internal-only and will not be listed
#                           in the FULL_BUILD or LITE_BUILD outputs.
#     lite_dependencies:  Add the current project to the `lite` matrix if any of these
#                           dependencies are dirty.
#     full_dependencies:  Add the current project to the `full` matrix if any of these
#                           dependencies are dirty.
#     include_regexes:    regexes that match files for this project
#     exclude_regexes:    regexes that exclude files from the included set
#     exclude_project_files: list of other project keys whose files should be
#                           excluded from this project

projects:
  # `core` collects any dirty files that are not matched by other projects. It
  # never appears in dependency lists because the script treats it specially,
  # triggering a full rebuild of all projects when any core file is dirty.
