Exceptive
Exceptive is a Python library that makes exception handling more programmatic and debuggable.
Usage
First, import exceptives packages for any exceptive class as such:
from exceptive import exceptives
Exception Handling with Object Methods
You can provide custom methods for exceptions:
class HelloWorld(exceptives.MethodicExceptive):
def run(self, name):
print("Hello "+name+"!")
def except_TypeError(self, exception):
print("Invalid value!")
# or you can use a logger here
func = HelloWorld()
func("world")
# Hello world!
func(5)
# Invalid value!
run function is the core of your object. When you call your object like
a function, whatever inside the run function will be executed.
In case you didn't register your exception as a method named
except_YourException, you can provide an except_else method to get
the exception instance and do what you want to do with it. Example;
class HelloWorld(exceptives.MethodicExceptive):
def run(self, name):
print("Hello "+name+"!")
def except_else(self, exception):
print("Something unexpected happened!")
func = HelloWorld()
func("world")
# Hello world!
func(5)
# Something unexpected happened!
Since the HelloWorld class above does not have any except_TypeError
method, the TypeError instance exception will be passed to except_else
method.
