toolrack.aio¶

toolrack.certificate¶

toolrack.collect¶

toolrack.config¶

toolrack.convert¶

toolrack.fsmap¶

Access the filesystem in a dict-like fashion.

This module provides a Directory class which provides access to the filesystem subtree below its path, allow accessing files and sub-directories as elements of a dict (e.g. directory['foo'] or directory['foo/bar']).

toolrack.fsmap.DIR = <object object>¶: Marker for creating directories.

class toolrack.fsmap.Directory(path)¶

Provide access to the sub-tree of a directrory.

It represents a directory in the filesystem:

directory = Directory('/base/path')

The object is iterable and yields names of contained elements:

for elem in directory:
    do_something(directory[elem])

Sub-directories and files below the base path can be accessed as items of a dict. For instance:

directory['a-dir']['a-file']

or even with a single access, using OS path format:

directory['a-dir/a-file']

Path elements can be removed with del:

del directory['a-file']
del directory['a-dir']  # this will delete the whole sub-tree

Files are created/overwritten by assiging content:

directory['a-file'] = 'some content'

and directories are created using the DIR marker:

directory['a-new-dir'] = DIR

toolrack.iterate¶

toolrack.json_util¶

Utilities for dealing with JSON data.

toolrack.json_util.indent(in_fd, out_fd, indent=4, ensure_ascii=False)¶

Indent JSON data.

It reads text in JSON format from in_fd and writes the formatted output to out_fd, using the specified amount of indent spaces.

Parameters:	in_fd – input file descriptor. out_fd – output file descriptor. indent (int) – number of spaces used for indentation. ensure_ascii (bool) – passed to the JSON serializer, if specified, non-ASCII characters are escaped.

toolrack.log¶

Logging helpers.

The Loggable mixin provides a logger attribute with a configured logger using the class name (including the module path) as logger name.

toolrack.log.LOG_FORMAT = '%(asctime)s - %(levelname)s - %(name)s - %(message)s'¶: Default format for logging to a stream

class toolrack.log.Loggable¶

Mixin class providing a logger attribute.

logger¶

Decorator to a class method a cached property.

The property method is called just the first time for an instance, and its result cached.

toolrack.log.setup_logger(name=None, stream=None, level=None, format='%(asctime)s - %(levelname)s - %(name)s - %(message)s')¶

Helper to setup a logger with a default handler.

Parameters:	name (str) – the name of the logger. If not specified, the `root` logger is used. stream – an output stream for the log handler. If not specified, the null handler is installed. level – the minimum log level for the logger.

toolrack.password¶

Password generation functions.

PasswordProfile defines a set of characters to use for generating password. It’s creating by passing a string with characters or character definitions encosed in curly braces (such as {alnum}, {num}, {alpha}), which are expanded to the corresponding set of characters.

For instance:

profile = PasswordProfile('{alpha}-_')
profile.generate(length=5)

yields a 5-chars password composed of letters, dashes and underscores.

toolrack.password.DEFAULT_CHARS = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~'¶: Default character set: letters, numbers and punctuation

toolrack.password.DEFAULT_LENGTH = 10¶: Default password length

class toolrack.password.PasswordProfile(definition)¶

A password profile, specifying how to generate a random password.

CHAR_DEFS = {'alnum': 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', 'alpha': 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ', 'num': '0123456789', 'punct': '!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~', 'space': ' \t\n\r\x0b\x0c'}¶

chars¶: Return the set of characters used in generation.

generate(length=10)¶: Generate a random password.

toolrack.password.generate_password(chars='abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!"#$%&\'()*+, -./:;<=>?@[\\]^_`{|}~', length=10)¶

Generate a random password using the supplied characters.

Parameters:	chars (str) – a string with chars to choose from. length (int) – number of chars for the password.

toolrack.path¶

Functions for paths handling.

toolrack.path.match_files(dirpaths, patterns, ignorecase=False)¶

Search files by name based on shell patterns.

Parameters:	dirpaths (list) – a list of paths to search from. patterns (list) – a list of name patterns to match.
Returns:	an iterator yielding matched files.

toolrack.property¶

Property decorators.

class toolrack.property.cachedproperty(func: Callable[[Any], Any])¶

Decorator to a class method a cached property.

The property method is called just the first time for an instance, and its result cached.

toolrack.script¶

toolrack.testing¶

toolrack.testing.fixtures¶

toolrack.threading¶

Thread-related utilities.

class toolrack.threading.ThreadLocalAttribute(name)¶

Descriptor to proxy access to a class attribute, making it thread-local.

This descriptor can be used to make a class attribute thread-local in a trasparent way:

class MyClass:

    attr = ThreadLocalAttribute('attr')

instance = MyClass()

The attribute will be normally accessible as instance.attr, but it’s stored in a threading.local() context.

toolrack.threading.thread_local_attrs(*attrs)¶

Class decorator to make attributes storage thread-local.

It should be passed names of attributes in the decorated class to make local:

@thread_local_attrs('foo', 'bar')
class MyClass:

    foo = 3
    bar = None
