# browseruse\_bench.utils.config\_loader

Configuration file loading utilities.

## Import

```python theme={null}
from browseruse_bench.utils import (
    load_config_file,
    resolve_benchmark_config,
    load_data_info,
    get_default_split,
)
```

***

## load\_config\_file

Load YAML configuration file.

```python theme={null}
def load_config_file(path: Path) -> Dict[str, Any]
```

<ParamField path="path" type="Path" required>
  Configuration file path
</ParamField>

<ResponseField name="return" type="dict">
  Configuration dictionary (empty dict if file not found)
</ResponseField>

<Note>
  If `pyyaml` is not installed, a built-in simplified YAML parser is used (supports basic key-value pairs only).
</Note>

***

## resolve\_benchmark\_config

Get Benchmark configuration.

```python theme={null}
def resolve_benchmark_config(
    config: Dict[str, Any],
    benchmark: str
) -> Dict[str, Any]
```

<ParamField path="config" type="dict" required>
  Main configuration dictionary
</ParamField>

<ParamField path="benchmark" type="str" required>
  Benchmark name
</ParamField>

<ResponseField name="return" type="dict">
  Configuration dictionary for the benchmark
</ResponseField>

<Warning>
  Raises `SystemExit` if benchmark does not exist.
</Warning>

### Usage Example

```python theme={null}
from browseruse_bench.utils import load_config_file, resolve_benchmark_config

config = load_config_file(Path("config.yaml"))
bench_config = resolve_benchmark_config(config, "lexbench-browser")
```

***

## load\_data\_info

Load benchmark's `data_info.json`.

```python theme={null}
def load_data_info(benchmark_path: Path) -> Dict[str, Any]
```

<ParamField path="benchmark_path" type="Path" required>
  Path to Benchmark directory
</ParamField>

<ResponseField name="return" type="dict">
  Contents of `data_info.json` (empty dict if file not found)
</ResponseField>

***

## get\_default\_split

Get default split.

```python theme={null}
def get_default_split(data_info: Dict[str, Any]) -> Optional[str]
```

Prioritizes `default_split` in `data_info`, otherwise prefers `All` or the first split key.

<ParamField path="data_info" type="dict" required>
  Contents of `data_info.json`
</ParamField>

<ResponseField name="return" type="str or None">
  Default split name, None if undetermined
</ResponseField>

### Usage Example

```python theme={null}
from browseruse_bench.utils import load_data_info, get_default_split
from pathlib import Path

data_info = load_data_info(Path("benchmarks/lexbench-browser"))
split = get_default_split(data_info)  # e.g., "All"
```
