class starlark_tugger.FileContent

This type represents the content of a single file.

Instances essentially track the following:

  • The content of a file (either a reference to a filesystem path or in-memory data).

  • Whether the file is executable.

  • The filename associated with the content. This is just the file name: directory components are not allowed.

Unfortunately, since Starlark doesn’t expose a bytes type, we are unable to expose the raw content tracked by instances of this type.



Whether a materialized file should be marked as executable.



The filename associated with this instance.

This is just the filename.

__init__(path: Optional[str] = None, filename: Optional[str] = None, content: Optional[str] = None, executable: Optional[bool] = None) FileContent

Construct a new instance given an existing filesystem path or string content.

1 of path or content must be provided to define the content tracked by this instance.

If content is provided, filename must also be provided.

filename must be just a file name: no directory components are allowed.

If path is provided, it must refer to an existing filesystem path or an error will occur. Relative paths are interpreted as relative to the global CWD variable. Absolute paths are used as-is.

If path is provided, by default filename and executable will be resolved from the given path. However, if the filename or executable arguments are not None, their values will be override those derived from path.

If content is provided and executable is not, executable defaults to False.

write_to_directory(path: str) str

Materialize this instance as a file in a directory.

Absolute paths are treated as is. Relative paths are relative to the currently configured build directory.

Returns the absolute path of the file that was written.
