useless-py

Useful python utilities with less effort.

Installation:

pip install useless-py

set_interval() function and @interval decorator - similar to Javascript's setInterval() method, uses gevent
set_timeout() function and @timeout decorator - similar to Javascript's setTimeout() method, uses gevent
set_time_limit() function and @time_limit decorator - limits the maximum execution time of a function, raises TimeLimitExceededError
@extends decorator - inheritance using a class decorator, inspired by Java's extends
@nocase decorator - class decorator that allows access to attributes regardless of coding style (camelCase or snake_case)
@didyoumean decorator - class decorator, raises DidYouMeanError (subclass of AttributeError) which suggest close matches

Check "samples" folder.

Class Decorators
- @extends - like Java's (instead of direct inheritance). IMO, more readable when you are doing multiple inheritance.
- @implements - like Java's (with the help of python "abc" module).
- @nocase - rewrite of "nocase" module using a class decorator instead of direct inheritance, more Pythonic, IMO. (https://pypi.python.org/pypi/nocase)
- @didyoumean - raises a "DidYouMean" exception (instead of AttributeError) when an attribute of an instance does not exist and suggests close matches. Think of "git" when you messed up on giving the correct argument:
```
C:\Users\Ronie Martinez>git hello
git: 'hello' is not a git command. See 'git --help'.
Did you mean one of these?
        help
        reflog
```
Context Managers
- Regular expressions in a "with" statement - I miss the old Perl $1, $2, $3 (special variables)... but global variable is an overkill, let's make a more Pythonic feature
