# Creates a group() that lists Python sources as |data|.
# Having such targets serves two purposes:
# 1) Causes files to be included in runtime_deps, so that they are uploaded to
# swarming when running tests remotely.
# 2) Causes "gn analyze" to know about all Python inputs so that tests will be
# re-run when relevant Python files change.
#
# All non-trivial Python scripts should use a "pydeps" file to track their
# sources. To create a .pydep file for a target in //example:
#
# build/print_python_deps.py \
# --root example \
# --output example/$target_name.pydeps \
# path/to/your/script.py
#
# Keep the .pydep file up-to-date by adding to //PRESUBMIT.py under one of:
# _ANDROID_SPECIFIC_PYDEPS_FILES, _GENERIC_PYDEPS_FILES
#
# Variables
# pydeps_file: Path to .pydeps file to read sources from (optional).
# data: Additional files to include in data. E.g. non-.py files needed by the
# library, or .py files that are conditionally / lazily imported.
#
# Example
# python_library("my_library_py") {
# pydeps_file = "my_library.pydeps"
# data = [ "foo.dat" ]
# }
template("python_library") {

# so that "gn analyze" will mark the target as changed when .py files
# are removed but none are added or modified.
