tea.utils
Module¶
-
tea.utils.
get_object
(path='', obj=None)¶ Returns an object from a dot path.
Path can either be a full path, in which case the get_object function will try to import the module and follow the path. Or it can be a path relative to the object passed in as the second argument.
Example for full paths:
>>> get_object('os.path.join') <function join at 0x1002d9ed8> >>> get_object('tea.process') <module 'tea.process' from 'tea/process/__init__.pyc'>
Example for relative paths when an object is passed in:
>>> import os >>> get_object('path.join', os) <function join at 0x1002d9ed8>
-
tea.utils.
load_subclasses
(klass, modules=None)¶ Load recursively all submodules of the modules and return all the subclasses of the provided class
Parameters:
-
tea.utils.compress.
unzip
(archive, destination, filenames=None)¶ Unzip the a complete zip archive into destination directory, or unzip a specific file(s) from the archive.
- Usage:
>>> output = os.path.join(os.getcwd(), 'output') >>> # Archive can be an instance of a ZipFile class >>> archive = zipfile.ZipFile('test.zip', 'r') >>> # Or just a filename >>> archive = 'test.zip' >>> # Extracts all files >>> unzip(archive, output) >>> # Extract only one file >>> unzip(archive, output, 'my_file.txt') >>> # Extract a list of files >>> unzip(archive, output, ['my_file1.txt', 'my_file2.txt']) >>> unzip_file('test.zip', 'my_file.txt', output)
Parameters:
-
tea.utils.compress.
mkzip
(archive, items, mode='w', save_full_paths=False)¶ Recursively zip a directory
Parameters:
-
tea.utils.compress.
seven_zip
(archive, items, self_extracting=False)¶ Create a 7z archive
-
tea.utils.compress.
seven_unzip
(archive, output)¶ Extract a 7z archive
-
tea.utils.crypto.
encrypt
(data, digest=True)¶ Performs encryption of provided data.
-
tea.utils.crypto.
decrypt
(data, digest=True)¶ Decrypts provided data.
-
class
tea.utils.daemon.
Daemon
(pidfile, stdin='/dev/null', stdout='/dev/null', stderr='/dev/null')¶ A generic daemon class.
Usage: subclass the Daemon class and override the run() method
-
daemonize
()¶ Do the UNIX double-fork magic
See Stevens’ “Advanced Programming in the UNIX Environment” for details (ISBN 0201563177) http://www.erlenstar.demon.co.uk/unix/faq_2.html#SEC16
-
start
(*args)¶ Start the daemon
-
stop
()¶ Stop the daemon
-
restart
(*args)¶ Restart the daemon
-
run
(*args)¶ You should override this method when you subclass Daemon.
It will be called after the process has been daemonized by start() or restart().
-
-
tea.utils.encoding.
smart_text
(s, encoding='utf-8', strings_only=False, errors='strict')¶ Returns a unicode object representing ‘s’. Treats bytes using the ‘encoding’ codec.
If strings_only is True, don’t convert (some) non-string-like objects.
-
tea.utils.encoding.
smart_bytes
(s, encoding='utf-8', strings_only=False, errors='strict')¶ Returns a bytes version of ‘s’, encoded as specified in ‘encoding’.
If strings_only is True, don’t convert (some) non-string-like objects.
