## Installation

```bash
pip install opendal
```

## Usage

fs service example:

```python
import opendal

op = opendal.Operator("fs", root="/tmp")
op.write("test.txt", b"Hello World")
print(op.read("test.txt"))
print(op.stat("test.txt").content_length)
```

Or using the async API:

```python
import asyncio

async def main():
    op = opendal.AsyncOperator("fs", root="/tmp")
    await op.write("test.txt", b"Hello World")
    print(await op.read("test.txt"))

asyncio.run(main())
```

s3 service example:

```python
import opendal

op = opendal.Operator("s3", root="/tmp", bucket="your_bucket_name", region="your_region")
op.write("test.txt", b"Hello World")
print(op.read("test.txt"))
print(op.stat("test.txt").content_length)
```

Or using the async API:

```python
import asyncio

async def main():
    op = opendal.AsyncOperator("s3", root="/tmp", bucket="your_bucket_name", region="your_region")
    await op.write("test.txt", b"Hello World")
    print(await op.read("test.txt"))

asyncio.run(main())
```

## Development

Setup virtualenv:

```shell
uv venv --python 3.11
```

Install all the dependencies:

```shell
uv sync --all-groups --all-extras
```

Run some tests:

```shell
# To run `test_write.py` and use `fs` operator
OPENDAL_TEST=fs OPENDAL_FS_ROOT=/tmp uv run pytest -vk test_write
```

Build API docs:

```shell
uv run mkdocs build
```
