These parsers are used -by [`Litestar`](https://github.com/litestar-org/litestar), but are developed separately - and can of course be used separately. - -> [!IMPORTANT]\ -> [**_Starlite has been renamed to Litestar_**](https://litestar.dev/about/organization.html#litestar-and-starlite) - -</div> - -## Installation - -```shell -pip install fast-query-parsers -``` - -## Usage - -The library exposes two function `parse_query_string` and `parse_url_encoded_dict`. - -### `parse_query_string` - -This function is used to parse a query string into a list of key/value tuples. - -```python -from fast_query_parsers import parse_query_string - -result = parse_query_string(b"value=1&value=2&type=dollar&country=US", "&") -# [("value", "1"), ("value", "2"), ("type", "dollar"), ("country", "US")] -``` - -The first argument to this function is a byte string that includes the query string to be parsed, the second argument is -the separator used. - -#### Benchmarks - -Query string parsing is more than x5 times faster than the standard library: - -```text -stdlib parse_qsl parsing query string: Mean +- std dev: 2.86 us +- 0.03 us -..................... -parse_query_string parsing query string: Mean +- std dev: 916 ns +- 13 ns -..................... -stdlib parse_qsl parsing urlencoded query string: Mean +- std dev: 8.30 us +- 0.10 us -..................... -parse_query_string urlencoded query string: Mean +- std dev: 1.50 us +- 0.03 us -``` - -### `parse_url_encoded_dict` - -This function is used to parse a url-encoded form data dictionary and parse it into the python equivalent of JSON types. - -```python -from urllib.parse import urlencode - -from fast_query_parsers import parse_url_encoded_dict - -encoded = urlencode( - [ - ("value", "10"), - ("value", "12"), - ("veggies", '["tomato", "potato", "aubergine"]'), - ("nested", '{"some_key": "some_value"}'), - ("calories", "122.53"), - ("healthy", "true"), - ("polluting", "false"), - ("json", "null"), - ] -).encode() - -result = parse_url_encoded_dict(encoded, parse_numbers=True) - -# result == { -# "value": [10, 12], -# "veggies": ["tomato", "potato", "aubergine"], -# "nested": {"some_key": "some_value"}, -# "calories": 122.53, -# "healthy": True, -# "polluting": False, -# "json": None, -# } -``` - -This function handles type conversions correctly - unlike the standard library function `parse_qs`. Additionally, it -does not nest all values inside lists. - -Note: the second argument passed to `parse_url_encoded_dict` dictates whether numbers should be parsed. If `True`, -the value will be parsed into an int or float as appropriate, otherwise it will be kept as a string. -By default the value of this arg is `True`. - -#### Benchmarks - -Url Encoded parsing is more than x2 times faster than the standard library, without accounting for parsing of values: - -```text -stdlib parse_qs parsing url-encoded values into dict: Mean +- std dev: 8.99 us +- 0.09 us -..................... -parse_url_encoded_dict parse url-encoded values into dict: Mean +- std dev: 3.77 us +- 0.08 us -``` - -To actually mimic the parsing done by `parse_url_encoded_dict` we will need a utility along these lines: - -```python -from collections import defaultdict -from contextlib import suppress -from json import loads, JSONDecodeError -from typing import Any, DefaultDict, Dict, List -from urllib.parse import parse_qsl - - -def parse_url_encoded_form_data(encoded_data: bytes) -> Dict[str, Any]: - """Parse an url encoded form data into dict of parsed values""" - decoded_dict: DefaultDict[str, List[Any]] = defaultdict(list) - for k, v in parse_qsl(encoded_data.decode(), keep_blank_values=True): - with suppress(JSONDecodeError): - v = loads(v) if isinstance(v, str) else v - decoded_dict[k].append(v) - return {k: v if len(v) > 1 else v[0] for k, v in decoded_dict.items()} -``` - -With the above, the benchmarks looks like so: - -```text -python parse_url_encoded_form_data parsing url-encoded values into dict: Mean +- std dev: 19.7 us +- 0.1 us -..................... -parse_url_encoded_dict parsing url-encoded values into dict: Mean +- std dev: 3.69 us +- 0.03 us -``` - -## Contributing - -All contributions are of course welcome! - -### Repository Setup - -1. Run `cargo install` to setup the rust dependencies and `poetry install` to setup the python dependencies. -2. Install the pre-commit hooks with `pre-commit install` (requires [pre-commit](https://pre-commit.com/)). - -### Building - -Run `poetry run maturin develop --release --strip` to install a release wheel (without debugging info). This wheel can be -used in tests and benchmarks. - -### Benchmarking - -There are basic benchmarks using pyperf in place. To run these execute `poetry run python benchrmarks.py`. - diff --git a/venv/lib/python3.11/site-packages/fast_query_parsers-1.0.3.dist-info/RECORD b/venv/lib/python3.11/site-packages/fast_query_parsers-1.0.3.dist-info/RECORD deleted file mode 100644 index fda3507..0000000 --- a/venv/lib/python3.11/site-packages/fast_query_parsers-1.0.3.dist-info/RECORD +++ /dev/null @@ -1,10 +0,0 @@ -fast_query_parsers-1.0.3.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4
