Use this module to easily parse a single, unique code containing as much information as your function or program needs, much as the bash 'chmod' command extracts 3 different file permissions from each number in 775.
| Code | Flags |
|---|---|
| 1 | [0] |
| 2 | [1] |
| 3 | [0, 1] |
| 4 | [2] |
| 5 | [0, 2] |
| 6 | [1, 2] |
| 7 | [0, 1, 2] |
| 8 | [3] |
| 9 | [0, 3] |
... and so on. This system relies on the fact that any integer can be broken down into a unique set of the members of the sequence y = 2^n. Basically, these are the members of the base-2 number system which can be represented with just a single digit set, which is to say they are capable of holding the most information.
Outside of a programmatic interface, call for example:
from flags import code
# set some constants
PRINT = 0
MODIFY = 1
EXTRACT = 2
ANNOTATE = 3
ACCESSIBILITY = 4
some_api(doc, code([PRINT, ANNOTATE, ACCESSIBILITY]))... specifying an arbitrary number of desired behaviors. Inside that inferface, call:
from flags import flags
def some_api(doc, code):
# code == 25
behaviors = flags(code)
# can't modify
if MODIFY in behaviors:
change_stuff(doc)
# can print
if PRINT in behaviors:
queue_print(doc)... and retrieve the list of integers, each representing a single behavior. Then do something with all that power!
