Is it possible to run a script every time any input is push into program?

I know I can do that for every input, but is it possible to define global triggers?

Why not the opposite and let a script constantly poll for a change ?

This is indeed a solution. Just a CPU intensive one.

If I understand correctly, you say have a script in a never-ending loop that checks if the program has changed and does what it needs to do.

This is definitely much more CPU intensive than an event-driven solution which runs what it needs to run only when an event occurs. (I guess this is what triggers do)


In an event-driven implementation, you have a single loop for the events that spawn registered callbacks.

Frankly i don't care. Question was if it was possible and indeed there is a solution

How much CPU % will it add for the practical convenience ?

Sorry, the question was if there are global triggers.

A solution that will make the CPU jump to 100% (of the thread since I guess the execution is per thread)

Anyway. Thank you for your help.
