>>> home_fs.close()
```

--------------------------------

### Open Current Directory using open_fs (Python)

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/guide.rst

Demonstrates opening the current working directory as an OSFS using `open_fs` without specifying a protocol, which defaults to OSFS. This is a convenient shorthand for accessing local files.

```python
>>> from fs import open_fs
>>> home_fs = open_fs('.')
>>> home_fs.listdir('/')
['world domination.doc', 'paella-recipe.txt', 'jokes.txt', 'projects']
```

--------------------------------

### Walk Directory for Specific Files

```

--------------------------------

### Get Path and Info Objects with Walk Info Method (Python)

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/walking.rst

This snippet demonstrates using the walk.info() method to get a generator of tuples, where each tuple contains a path and its corresponding fs.info.Info object. This allows checking if a path refers to a directory or file using the info.is_dir attribute.

```Python
from fs import open_fs
home_fs = open_fs('~/projects')
for path, info in home_fs.walk.info():
    if info.is_dir:
        print("[dir] {}".format(path))
    else:
        print("[file] {}".format(path))
```

--------------------------------

### Copy Specific Files Using Walker Filter

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/guide.rst

```python
from fs.copy import copy_fs

copy_fs('~/projects', 'zip://projects.zip')
```

--------------------------------

### Walk Files Recursively Using FS Object Walk Attribute (Python)

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/walking.rst

This example shows a more concise way to recursively walk a filesystem and print Python file paths by using the 'walk' attribute directly on the filesystem object. This approach avoids explicit instantiation of the Walker class, leveraging the BoundWalker object associated with the filesystem.

```Python
from fs import open_fs
home_fs = open_fs('~/projects')
for path in home_fs.walk.files(filter=['*.py']):
    print(path)
```

--------------------------------

### Thread-Safe FileSystem Method Example (Python)

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/implementers.rst

```python
from fs import open_fs

my_fs = open_fs('~/my_files')

# Write bytes
my_fs.writebytes('output.bin', b'\x01\x02\x03')

# Write text (encoded as UTF-8 by default)
my_fs.writetext('log.txt', 'This is a log message.')
```

--------------------------------

### Listing Directory Contents with scandir in Python

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/guide.rst

Demonstrates the use of `scandir` to obtain an iterable of `Info` objects, providing more detailed information than `listdir`. The `Info` objects contain attributes like `is_dir` and can include details such as size and modification time if requested.

```python
>>> directory = list(home_fs.scandir('/projects'))
>>> directory
[<dir 'fs'>, <dir 'moya'>, <file 'README.md'>]
```

```python
>>> directory = code_fs.filterdir('/', files=['*.py'], namespaces=['details'])
>>> sum(info.size for info in directory)
```

--------------------------------

### Read File Contents as Bytes and Text

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/guide.rst

Demonstrates reading file contents directly as bytes or decoded text using PyFilesystem2's optimized methods. These methods bypass the need for explicit file opening and can offer performance benefits.

```python
from fs import open_fs

my_fs = open_fs('~/my_files')

# Read as bytes
file_bytes = my_fs.readbytes('data.bin')

# Read as text (decoded as UTF-8 by default)
file_text = my_fs.readtext('config.txt')
```

--------------------------------

### Get OS System Path - Python

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/concepts.rst

Retrieves the operating system's absolute path for a given PyFilesystem path. This is crucial for modules that require OS-level path compatibility. It converts a path within the FS context to an OS-understood format. Raises `NoSysPath` if the filesystem does not map to a system path.

```python
from fs.osfs import OSFS

home_fs = OSFS('~/')
system_path = home_fs.getsyspath('test.txt')
print(system_path)
```

--------------------------------

```python
from fs.osfs import OSFS
from fs.multifs import MultiFS

theme_fs = MultiFS()
theme_fs.add_fs('templates', OSFS('templates'))
theme_fs.add_fs('theme', OSFS('theme'))
```

from ._s3fs import S3FS


class S3FSOpener(Opener):
    protocols = ['s3']

    def open_fs(self, fs_url, parse_result, writeable, create, cwd):
        bucket_name, _, dir_path = parse_result.resource.partition('/')
        if not bucket_name:
            raise OpenerError(
                "invalid bucket name in '{}'".format(fs_url)
            )
        s3fs = S3FS(
            bucket_name,
            dir_path=dir_path or '/',
            aws_access_key_id=parse_result.username or None,
            aws_secret_access_key=parse_result.password or None,
        )
        return s3fs

```

### Iterate Directory Steps with Walk Method (Python)

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/walking.rst

This code snippet demonstrates iterating through directory traversal steps using the walk() method on a filesystem object. Each step provides the current directory path, a list of sub-directory Info objects, and a list of file Info objects.

```Python
from fs import open_fs
home_fs = open_fs('~/projects')
for step in home_fs.walk(filter=['*.py']):
    print('In dir {}'.format(step.path))
    print('sub-directories: {!r}'.format(step.dirs))
    print('files: {!r}'.format(step.files))
```

--------------------------------

### Requesting Multiple Namespaces in PyFilesystem

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/info.rst

Shows how to request specific namespaces ('details' and 'access') when retrieving resource information. This allows fine-grained control over the data fetched for a file.

```python
resource_info = fs.getinfo('myfile.txt', namespaces=['details', 'access'])
```

--------------------------------

### Check Documentation Style

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/CONTRIBUTING.md

### Mounting Filesystems with MountFS in Python

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/reference/mountfs.rst

Demonstrates how to use the MountFS class from pyfilesystem2 to combine multiple filesystems. It creates a virtual filesystem where paths under specified mount points are directed to their respective underlying filesystems. Dependencies include the 'fs' library. The input consists of existing filesystem objects, and the output is a unified MountFS object.

```python
from fs.mountfs import MountFS

combined_fs = MountFS()
combined_fs.mount('config', config_fs)
combined_fs.mount('resources', resources_fs)

print(combined_fs.gettext('/config/defaults.cfg'))
read_jpg(combined_fs.open('/resources/images/logo.jpg', 'rb'))
```

--------------------------------

### Check Code Formatting with Black

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/CONTRIBUTING.md

Runs the 'black' code formatter to ensure consistent code style across the project. This command is executed within the 'codeformat' tox environment.

```shell
tox -e codeformat
```

--------------------------------

### Handling Missing Info Namespaces in Python

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/info.rst

Demonstrates how to gracefully handle situations where a required namespace is not present in the file information. It shows both a try-except block for catching MissingInfoNamespace and a check using has_namespace.

```python
from fs import errors

try:
    print('user is {}'.format(info.user))
except errors.MissingInfoNamespace:
    # No 'access' namespace
    pass

if info.has_namespace('access'):
    print('user is {}'.format(info.user))
```

--------------------------------

### Run Specific Tox Environment (Python 3.9)

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/CONTRIBUTING.md

Runs tests using a specific tox environment, in this case, 'py39' for Python 3.9. This allows for faster iteration when testing against a particular Python version.

```shell
tox -e py39
```

--------------------------------

### Walk Files Recursively with Walker Filter (Python)

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/walking.rst

This snippet demonstrates how to recursively walk a filesystem and print the paths of all Python files. It utilizes the Walker class with a filter to specify the file pattern. The Walker object is instantiated with the filter and then used with the files() method on a bound filesystem object.

```Python
from fs import open_fs
from fs.walk import Walker
home_fs = open_fs('~/projects')
walker = Walker(filter=['*.py'])
for path in walker.files(home_fs):
    print(path)
```

--------------------------------

### Run Type Checking with Mypy

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/CONTRIBUTING.md

Executes 'mypy' for static type checking, using type annotations written as comments for Python 2.7 compatibility. This is performed using the 'typecheck' tox environment.

```shell
tox -e typecheck
```

--------------------------------

### Iterate and Print Python Files using Glob

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/globbing.rst

Demonstrates how to use the `glob` attribute to find all Python files recursively in a filesystem and print their paths and sizes. It returns an iterator of `GlobMatch` objects.

```python
for match in my_fs.glob("**/*.py"):
    print(f"{match.path} is {match.info.size} bytes long")
```

--------------------------------

### Open Subdirectory with Sandboxing - Python

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/concepts.rst

Creates a new FS object that represents a subdirectory, effectively sandboxing operations to that specific directory. This is useful for passing FS objects to functions that should not have access to the parent filesystem. Operations on the returned FS object are relative to the subdirectory's root.

```python
from fs.osfs import OSFS

# Assuming 'foo' is a directory containing 'bar'
foo_fs = OSFS('foo')
bar_fs = foo_fs.opendir('bar')

# Now, operations on bar_fs are relative to 'foo/bar'
# For example, bar_fs.getsyspath('readme.txt') would resolve correctly
print(bar_fs.getsyspath('readme.txt'))
```

--------------------------------

### Count Python Lines of Code with Standard Library

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/README.md

This function counts non-blank lines of Python code in a local directory using Python's standard `os` module. It demonstrates the traditional approach without filesystem abstraction, requiring manual handling of directory traversal and file paths. Dependencies include the `os` module.

```python
import os

def count_py_loc(path):
    """Count non-blank lines of Python code using standard library."""
    count = 0
    for root, dirs, files in os.walk(path):
        for name in files:
            if name.endswith('.py'):
                with open(os.path.join(root, name), 'rt') as python_file:
                    count += sum(1 for line in python_file if line.strip())
    return count

# Example usage:
# print(count_py_loc('/path/to/your/projects'))
```

--------------------------------

### Count Python Lines of Code with PyFilesystem2

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/README.md

This function iterates through all `.py` files in a given filesystem (recursively) and counts the non-blank lines of code. It leverages PyFilesystem2's `walk.files` and `open` methods for a unified interface across different storage types. Dependencies include the `fs` library.

```python
from fs import open_fs

def count_python_loc(fs):
    """Count non-blank lines of Python code."""
    count = 0
    for path in fs.walk.files(filter=['*.py']):
        with fs.open(path) as python_file:
            count += sum(1 for line in python_file if line.strip())
    return count

# Example usage for local directory:
projects_fs = open_fs('~/projects')
print(count_python_loc(projects_fs))

# Example usage for a zip file:
# projects_fs = open_fs('zip://projects.zip')
# print(count_python_loc(projects_fs))

# Example usage for an FTP server:
# projects_fs = open_fs('ftp://ftp.example.org/projects')
# print(count_python_loc(projects_fs))
```

--------------------------------

### Check Code Style with Flake8

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/CONTRIBUTING.md

Invokes flake8, a tool for checking Python code style according to PEP8 guidelines, along with common plugins. This is typically run within a tox environment ('codestyle').

```shell
tox -e codestyle
```

--------------------------------

### Remove .pyc Files Recursively using Glob

Source: https://github.com/pyfilesystem/pyfilesystem2/blob/master/docs/source/globbing.rst

Shows how to use the `glob` method combined with the `remove` method to efficiently delete all files matching a specific pattern (e.g., '.pyc' files) recursively within a directory. This operation returns the number of files removed.

```python
import fs

fs.open_fs('~/projects/my_project').glob('**/*.pyc').remove()
```
