@spec by_config_and_split(map(), String.t() | nil, String.t() | nil) :: {:ok, map()}

Filters repository files by configuration name and split.

Parameters

• repo_files - map of files from repository (%{filename => etag})
• name - optional configuration name to filter by
• split - optional split name to filter by (e.g., "train", "test")

Returns

{:ok, filtered_files} where filtered_files is a map of matching files.

Examples

iex> files = %{"train.csv" => nil, "test.csv" => nil}
iex> ElixirDatasets.Filter.by_config_and_split(files, nil, "train")
{:ok, %{"train.csv" => nil}}

@spec by_config_name(map() | list(), String.t() | nil) :: map() | list()

Filters files by configuration name.

If config_name is nil, returns all files unchanged. Otherwise, returns only files whose path contains the config name.

Parameters

• repo_files - map or list of files
• config_name - optional configuration name to filter by

Returns

Filtered files in the same format as input (map or list).

@spec by_split(map() | list(), String.t() | nil) :: map() | list()

Filters files by split name.

If split is nil, returns all files unchanged. Otherwise, returns only files whose basename (without extension) contains the split name.

Parameters

• repo_files - map or list of files
• split - optional split name to filter by (e.g., "train", "test", "validation")

Returns

Filtered files in the same format as input (map or list).

Examples

iex> files = %{"train.csv" => nil, "test.csv" => nil, "validation.csv" => nil}
iex> ElixirDatasets.Filter.by_split(files, "train")
%{"train.csv" => nil}
