terse 0.0.4

a collection of function decorators to handle common procedures done on the entry and exit points.

This module provides a collection of function decorators to handle common procedures done on the entry and exit points.

Directory

In Directory

Before the function is executed, the current working directory is saved and the directory is changed to the provided path. After the function has completed, the directory is changed to the saved working directory.

from terse import in_dir
from glob import glob
import os

@in_dir('/sys/class/net')
def interfaces():
  return glob('*')

print(os.getcwd())
print(interfaces())
print(os.getcwd())

On Exit

No Exception

Decorator will catch all exceptions leaked or produced by callee. If provided with callback function, then the callback will only be invoked when an exception occurs. If provided with instead_return, then the value will be returned when an exception occurs.

from terse import no_except

def simple_log(function, exception):
  print(exception)

@no_except(instead_return=False)
def example(raise_exception=False):
  if raise_exception:
    raise Exception("exception from example")
  return True

assert example()
assert example(False) == False
