Description:

pyjsonl 1.1.2

jsonl

About
Useful functions for working with jsonlines data as
described: https://jsonlines.org/
Features:

Exposes an API similar to the json module from the standard library.
Supports orjson, ujson libraries or standard json for serialization/deserialization, prioritizing orjson,
then ujson, and defaulting to the standard json if none are installed.
Supports gzip and bzip2 compression formats.

Installation (via pip)
pip install py-jsonl
Usage
dumps
Serialize an iterable into a jsonlines formatted string.
dumps(iterable, **kwargs)

:param Iterable[Any] iterable: Iterable of objects
:param kwargs: `json.dumps` kwargs
:rtype: str

Examples:
import jsonl

data = ({'foo': 1}, {'bar': 2})
result = jsonl.dumps(data)
print(result) # >> '{"foo": 1}\n{"bar": 2}\n'

dump
Dump an iterable to a jsonlines file.

Use (.gz, .gzip, .bz2) extensions to dump the compressed file.
Dumps falls back to the following functions: (orjson.dumps, ujson.dumps, and json.dumps).

dump(iterable, file, **kwargs)

:param Iterable[Any] iterable: Iterable of objects
:param Union[str | bytes | os.PathLike | io.IOBase] file: File to dump
:param kwargs: `json.dumps` kwargs

Examples:
import gzip

import jsonl

data = ({'foo': 1}, {'bar': 2})

# Dump the data into an uncompressed file at the given path.
jsonl.dump(data, "file1.jsonl")

# Dump the data into a gzipped file at the given path.
jsonl.dump(data, "file2.jsonl.gz")

# Dump the data into the already opened gzipped file.
with gzip.open("file3.jsonl.gz", mode="wb") as fp:
jsonl.dump(data, fp)

# Append the data to the end of the existing gzipped file.
with gzip.open("file3.jsonl.gz", mode="ab") as fp:
jsonl.dump(data, fp)

dump_fork
Incrementally dumps multiple iterables into the specified jsonlines file paths,
effectively reducing memory consumption.

Use (.gz, .gzip, .bz2) extensions to dump the compressed file.
Dumps falls back to the following functions: (orjson.dumps, ujson.dumps, and json.dumps).

dump_fork(path_iterables, dump_if_empty=True, **kwargs)

:param Iterable[str, Iterable[Any]] path_iterables: Iterable of iterables by filepath
:param bool dump_if_empty: If false, don't create an empty jsonlines file.
:param kwargs: `json.dumps` kwargs

Examples:
import jsonl

path_iterables = (
("num.jsonl", ({"value": 1}, {"value": 2})),
("foo.jsonl", ({"a": "1"}, {"b": 2})),
("num.jsonl", ({"value": 3},)),
("foo.jsonl", ()),
)
jsonl.dump_fork(path_iterables)

load
Deserialize a UTF-8-encoded jsonlines file into an iterable of Python objects.

Recognizes (.gz, .gzip, .bz2) extensions to load compressed files.
Loads falls back to the following functions: (orjson.loads, ujson.loads, and json.loads).

def load(file, **kwargs)

:param Union[str | bytes | os.PathLike | io.IOBase] file: File to load
:param kwargs: `json.loads` kwargs
:rtype: Iterable[Any]

Examples:
import gzip

import jsonl

# Load the uncompressed file from the given path.
iterable1 = jsonl.load("file1.jsonl")
print(tuple(iterable1))

# Load the gzipped file from the given path.
iterable2 = jsonl.load("file2.jsonl.gz")
print(tuple(iterable2))

# Load the gzipped file from the given open file.
with gzip.open("file3.jsonl.gz", mode="rb") as fp:
iterable3 = jsonl.load(fp)
print(tuple(iterable3))
