# The following proxies various utilities from pwnlibs by explicitly importing them
# To replace a "from pwn import *" remove it and let your IDE highlight all missing methods (Hint: F2 in PyCharm goes to next error)
# import the missing (and only the missing!) methods from this module, e.g. with "from internalblue.utils import term, read, log, text, options"
# In some cases like "from pwn import socket" this just imports another module.
# Use an IPython shell to run "from pwn import *" and check where some method/module actually comes from and either import it directly or add it to this module

# The packers like u8 are generated in a fairly convoluted way that breaks IDE introspection.
# The following code remedies this by:
# - Explicitly defining a stub function with type annotations
# - Generating all the packers like pwnlibs would
# - Only if if the current module already has the name of the packer as an attribute (i.e. has a stub function defined) it will be replaced with the pwnlibs version
#
# This means:
# - All import issues in the rest of the code are genuine as the imports are only available if an explicit stub function is added
# - The functions can be easily replaced by just implementing them and removing the for loop at the end
