FileManifest

class starlark_tugger.FileManifest

The FileManifest type represents a set of files and their content.

FileManifest instances are used to represent things like the final filesystem layout of an installed application.

Conceptually, a FileManifest is a dict mapping relative paths to file content.

add_manifest(manifest: FileManifest)

This method overlays another :py:class`FileManifest` on this one. If the other manifest provides a path already in this manifest, its content will be replaced by what is in the other manifest.

add_file(content: FileContent, path: Optional[str] = None, directory: Optional[str] = None)

Add a FileContent instance to this manifest, optionally controlling its path within the manifest.

If neither path nor directory are specified, the file will be materialized in the root directory of the manifest with the filename given by FileContent.filename.

If path is provided, it defines the exact path within the manifest to use.

If directory is provided, the manifest path is effectively computed the same as os.path.join(directory, content.filename).

An error occurs if both path and directory are non-None.

add_path(path: str, strip_prefix: str, force_read: bool = False)

This method adds a file on the filesystem to the manifest.

The following arguments are accepted:

path

The filesystem path to add.

strip_prefix

The string prefix to strip from the path. The remaining path will be stored in the manifest.

force_read

Whether to read the file data into memory now.

This can be set when reading temporary files.

get_file(path: str) → Optional[FileContent]

Obtain a FileContent at a given path in the manifest, or None if no such path exists in the manifest.

A copy of the content in the FileManifest is returned and mutations on the returned object will not be reflected in the FileManifest.

install(path: str, replace: bool = True)

This method writes the content of the FileManifest to a directory specified by path. The path is evaluated relative to the path specified by BUILD_PATH.

If replace is True (the default), the destination directory will be deleted and the final state of the destination directory should exactly match the state of the FileManifest.

Upon successful materialization of all files in the manifest, all written files will be assessed for code signing with the file-manifest-install action.

paths() → list[str]

Obtain all paths currently tracked by this instance.

remove(path: str) → Optional[FileContent]

Remove the entry in this manifest at path, returning a FileContent representing the removed entry if there was one or None if the path isn’t tracked by the manifest.
