params_file public API
params_file(name, out, args, data, newline, kwargs)
Generates a UTF-8 encoded params file from a list of arguments.
Handles variable substitutions for args.
| Name | Description | Default Value |
|---|---|---|
| name | Name of the rule. | none |
| out | Path of the output file, relative to this package. | none |
| args | Arguments to concatenate into a params file. - Subject to 'Make variable' substitution. See https://docs.bazel.build/versions/main/be/make-variables.html. - Subject to predefined source/output path variables substitutions. The predefined variables execpath, execpaths, rootpath, rootpaths, location, and locations take label parameters (e.g. $(execpath //foo:bar)) and substitute the file paths denoted by that label.See https://docs.bazel.build/versions/main/be/make-variables.html#predefined_label_variables for more info. NB: This $(location) substition returns the manifest file path which differs from the _binary & _test args and genrule bazel substitions. This will be fixed in a future major release. See docs string of expand_location_into_runfiles macro in internal/common/expand_into_runfiles.bzl for more info.- Subject to predefined variables & custom variable substitutions. Predefined "Make" variables such as $(COMPILATION_MODE) and $(TARGET_CPU) are expanded. See https://docs.bazel.build/versions/main/be/make-variables.html#predefined_variables.Custom variables are also expanded including variables set through the Bazel CLI with --define=SOME_VAR=SOME_VALUE. See https://docs.bazel.build/versions/main/be/make-variables.html#custom_variables.Predefined genrule variables are not supported in this context. |
