Useful Tools

Luna: simple version control system

"luna" can mean anything, depending on your mood.

  • the goddess of the moon in Roman mythology: isn't it great?
  • "light unix-like navigating assistant": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
  • "loony unsteady nerd as**ole": when it breaks
  • Luna Lovegood in HP: correct!

(1) installation

  • method 1: python -- recommended
import wzk.luna
  • method 2: shell
#change PATH to the absolute path of wzk/
#change .bashrc if using another shell. e.g. ~/.zshrc
echo "alias luna='python PATH/' " >> ~/.bashrc
source ~/.bashrc
#for single trial, "alias luna='python PATH/'" is enough

(2) Use in shell (command line) -- recommended

Note: support Linux and Mac OS (try git bash if using Windows)

mkdir test
cd test
luna init
touch 666.txt
luna commit "first commit"
touch hahaha
echo "hello world" >> 666.txt
luna diff
luna commit "second commit"
luna log
luna diff 1 2
luna diff 1 666.txt
luna reset 1
luna reset 2
luna history
luna delete 1
luna info
luna discard

(3) Use in python

from wzk.luna import *
p = "~/Desktop/"
makefile(p, "1")
commit(p, "commit 1")
makefile(p, "2")
commit(p, "commit 2")
revise(p, 2, "commit 3 new message")
reset(p, 1)
reset(p, 2)

send email

Send email with SMTP

import wzk
mail_host = ...
mail_user = ...
mail_pass = ...
sender = wzk.parser.MailSender(mail_host, mail_user, mail_pass)
sender.send_mail(title="hi~", content="nothing~", receiver=None)

check web page update

Automatically check web page and send notification email upon update

import wzk
mail_host = ...
mail_user = ...
mail_pass = ...
checker = wzk.parser.WebPageUpdateChecker(mail_host, mail_user, mail_pass, cookies=None)
checker.check("", interval=10)

check system information

see information on your system and python

from wzk.os import *

For Developers

improved data structure

Dictionary supporting inverse-mapping and attribute-indexing

Number type supporting setting bound and loop

from wzk import DD, N

a = DD({"good": "kk"})
a.bad = "nyima"

b = N(4, upper_bound=8, lower_bound=3)
b += 5
c = N(4, upper_bound=8, lower_bound=3, loop=True)

interestring utensils

Several interesing utensils

import time
from wzk import ErrorFucker, Separate, Clock

with ErrorFucker(raises=False) as ef1:
    d1 = int("f")

with Separate("separate zone", count=True) as s:

with s:
    with Clock("test") as c:

with ErrorFucker(raises=True) as ef2:
    d2 = int("d")

simplified pytorch(?)

Scalar autograd mechanism

from wzk.autograd.thing import *

a = thing(2)
b = thing(3)
c = a + leaky_relu(b)
d = thing(5) 
e = tanh(d) 
f = relu(e)
g = log(f)

print(a, b, c, d, e, f, g)
