Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
BitBooleanFlags - Wrapper Syntax'ed #
Bit boolean flag wrapper, allows you to store flags inside a single number. Each flag uses powers of two, and the number of flags you can store depends on the capacity of the numeric data type. You can do combined and or operations on the flag as per your requirement, refer examples.
Installation
Use the package manager pip.
pip install bit-boolean-flagsSample
from BitBooleanFlags import BitBooleanFlags
#initialize with a set of static flags which are available to set
BBF = BitBooleanFlags("CREATE_FOLDER","CREATE_FILE","DELETE_FILE","DELETE_FOLDER","KILL_PROCESS","ROOT_ACCESS")
#For example's sake
process1 = 0;
process2 = 0;
process3 = 0;
#add Permissions
process1 = BBF(process1).add("CREATE_FILE","DELETE_FILE")
#Inherit process1 flags and add new ones
process2 = BBF(process2).add("DELETE_FOLDER","CREATE_FOLDER")
#in addition to process 1 and two flags
process3 = BBF(process1,process2).add("KILL_PROCESS","ROOT_ACCESS","ROOT_ACCESS")
print("Permission List with Basic has: ")
for flag in BBF.mappedFlags():
print("Process 1 => " + flag + " : " + str(BBF(process1).has(flag)))
for flag in BBF.mappedFlags():
print("Process 2 => " + flag + " : " + str(BBF(process2).has(flag)))
for flag in BBF.mappedFlags():
print("Process 3 => " + flag + " : " + str(BBF(process3).has(flag)))
print("orHas(): ")
print("Process 1 => ROOT_ACCESS or CREATE_FILE : "+ str(BBF(process1).orHas("ROOT_ACCESS","CREATE_FILE")))
print("has(): and operation")
print("Process 2 => DELETE_FOLDER and CREATE_FOLDER : "+ str(BBF(process2).has("DELETE_FOLDER","CREATE_FOLDER")))
#store process1,process2,process3 in db or another storage medium as it is a number.Contributing
