CG Event 2016, Материалы к выступлению: GIT

Не большая презентация о GIT
part 2: GIT
пример работы с GIT на примере простых Nuke скриптов
git: video 1
git: video 2

так можно переопределить текстовый редактор Vim при commit
git config --global core.editor "'D:/Program Files/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"
git config -l

чтобы достучаться через proxy
git config --global http.proxy http://[user]:[password]@[ip adress]:8080
git config --global --get http.proxy

добавить все файлы
git add .

исключить некоторые типы файлов из добавления в репозиторий
нужно создать файл .gitignore его содержание:
/.sources
/docs
*.bak
*~
*.db
*.pyc
файлы из указанных папок и указанных типов не будут добавляться в репозиторий

How can I create documentation with sphinx library

# генерация содержимого папки lib в папку docs/rst
sphinx-apidoc -o docs/rst .

# генерировать документацию

make html

для преодоления ошибок экранируем символы * обратной чертой \

"\*.py"

комментарии пишем с пропуском строки перед аргументами и внимательно относясь к отступам. Например:

text

arg:

comment

in the comment you can print :
for bold string:

- **parameters**, **types**, **return** and **return types**::

for parametrs


parameters using :param <name>: <description>
type of the parameters :type <name>: <description>
returns using :returns: <description>
examples (doctest)
seealso using .. seealso:: text
notes using .. note:: text
warning using .. warning:: text
todo .. todo:: te

How can I get the current time in python

-----------------------------------------
import time
time.asctime()
>>> 'Sat May 21 01:34:38 2016'

import time
gmtime = time.gmtime(time.time())
ftime = '%a %d %b %Y %H:%M:%S GMT'
str = time.strftime(ftime, gmtime)
str
>>> 'Fri 20 May 2016 22:35:40 GMT'

----------------------------------------
import email.utils

email.utils.formatdate()
>>> 'Fri, 20 May 2016 22:37:02 -0000'

email.utils.formatdate(localtime=True)
>>> 'Sat, 21 May 2016 01:36:46 +0300'

email.utils.formatdate(usegmt=True)
>>> 'Fri, 20 May 2016 22:36:57 GMT'

----------------------------------------
from datetime import datetime

print datetime.now()
>>> 2016-05-21 01:38:16.661000

print datetime.now().time()
>>> 01:38:27.261000

print datetime.utcnow()
>>> 2016-05-20 22:39:04.538000

now = datetime.now()
print '{}:{}:{}'.format(now.hour, now.minute, now.second)
>>> 1:40:12

How can I see or clear Nuke memory usage

nuke.clearRAMCache()
nuke.clearDiskCache()

def bytesto(bytes, to, bsize=1024):
"""convert bytes to megabytes, etc.
sample code:
print('mb= ' + str(bytesto(314575262000000, 'm')))
sample output:
mb= 300002347.946
"""
a = {'k': 1, 'm': 2, 'g': 3, 't': 4, 'p': 5, 'e': 6}
r = float(bytes)
# print 'r {}'.format(r)
for i in range(a[to]):
r = r / bsize

return (r)

print nuke.memory("info")
print nuke.memory("info", 'Read1')

print '{} Mb'.format(bytesto(nuke.memory("free"),'m'))
print '{} Mb'.format(bytesto(nuke.memory("usage"),'m'))
print '{} Mb'.format(bytesto(nuke.memory("total_ram"),'m'))
print '{} Gb'.format(bytesto(nuke.memory("total_vm"),'g'))

read about memory options:
print help(nuke.memory)

How do I read menu object in Nuke

inside the menu.py in Nuke, write global variable
n = nuke.menu('Nuke')

I can read the value of this object

print n.items().pop().items()[0].name()
print n.items().pop().items()[0].script()
print n.items().pop().items()[0].shortcut()

for menu_item in n.items():
print menu_item.name()
for menu_sub in menu_item.items():
try:
print '...{}'.format(menu_sub.name())
print '...{}'.format(menu_sub.script())
# print '...{}'.format(menu_sub.shortcut())
except:
pass
=========================
# Result: File

...nuke.scriptNew("")
...Open Comp...
...nuke.scriptOpen("")
...Open Recent Comp
...Close Comp
...nuke.scriptClose()

and so on

How do I write try...except in one string

1. for nuke:
exec('try:\n n = nuke.toNode(\'DisableNodeController\'); k = n.knob(\'disable\'); k.setValue(0);\nexcept:\n nuke.message(\'DisableNodeController is not in scene\')')

2. second variant
def safecall(f, default=None, exception=Exception):
'''Returns modified f. When the modified f is called and throws an
exception, the default value is returned'''
def _safecall(*args,**argv):
try:
return f(*args,**argv)
except exception:
return default
return _safecall

[safecall(int)(i) for i in '1 2 x'.split()] # returns [1, 2, None]

[safecall(int, -1, ValueError)(i) for i in '1 2 x'.split()] # returns [1, 2, -1]

How print module attributes in the readable form

# easy function print list of the module attributes
# in the readable form
def print_module_attr(module, step_in=7):

        num_line = int(ceil( len(attr_list)/step_in ))
        for i in range(num_line):
            print attr_list[i*step_in: (i+1)*step_in]
    except ValueError as e:
        print 'step_in must be not zero,\n error: {}'.format(e)
        return
    except TypeError as e:
        print 'step_in must be int type,\n error: {}'.format(e)
        return

def test_print_module_attr():

    print_module_attr(os, 8)

    temp = 'test'; print temp
    print_module_attr(temp, 8)

    temp = 1; print temp
    print_module_attr(temp, 8)
