Args template_ctx.args()

Returns an Args object that can be used to build memory-efficient command lines.

declare_file

File template_ctx.declare_file(filename, *, directory)

Declares that implementation creates a file with the given filename within the specified directory. Remember that in addition to declaring a file, you must separately create an action that emits the file. Creating that action will require passing the returned File object to the action’s construction function.

Parameters

Parameter	Description
`filename`	string; required The relative path of the file within the directory.
`directory`	File; required The directory in which the file should be created.

run

None template_ctx.run(*, outputs, inputs=[], executable, tools=None, arguments=[], progress_message=None)

Creates an action that runs an executable.

Parameters

Parameter	Description
`outputs`	sequence of Files; required List of the output files of the action.
`inputs`	sequence of Files; or depset; default is `[]` List or depset of the input files of the action.
`executable`	File; or string; or FilesToRunProvider; required The executable file to be called by the action.
`tools`	sequence; or depset; or `None`; default is `None` List or `depset` of any tools needed by the action. Tools are executable inputs that may have their own runfiles which are automatically made available to the action. When a list is provided, it can be a heterogenous collection of: * `File`s * `FilesToRunProvider` instances * `depset`s of `File`s `File`s from `ctx.executable` and `FilesToRunProvider`s which are directly in the list will have their runfiles automatically added. All tools are implicitly added as inputs.
`arguments`	sequence; default is `[]` Command line arguments of the action. Must be a list of strings or `actions.args()` objects.
`progress_message`	string; or `None`; default is `None` Progress message to show to the user during the build.
