iroiro 0.3.1

Some cute utilties for my other projects

iroiro

A swiss-knife-like library that collects cute utilities for my other projects.

This library only depends on Python standard library and Python itself. It's functionalities will not depend on any third-party packages in a foreseeable future.

Examples:

# color strings
import iroiro
iroiro.orange('TEXT')   # \033[38;5;214mTEXT\033[m

# Invoke external command and retrieve the result.
p = iroiro.run(['seq', '5'])
p.stdout.lines  # ['1', '2', '3', '4', '5']

# Invoke external command and retrieve the result in a non-blocking manner.
# Functions could be used as command, so they could be mixed in pipe line.
p1 = iroiro.command(['seq', '5'])

def func(streams, *args):
    for line in streams[0]:
        streams[1].writeline('iro: {}'.format(line))

p2 = iroiro.command(func, stdin=True)

iroiro.pipe(p1.stdout, p2.stdin)
p1.run()
p2.run()
p2.stdout.lines   # ['iro: 1', 'iro: 2', 'iro: 3', 'iro: 4', 'iro: 5']

From my own perspective, Python's subprocess interface is not friendly enough for simple uses.
