How To Install elpa-fsm on Kali Linux
Introduction
In this tutorial we learn how to install elpa-fsm
on Kali Linux.
What is elpa-fsm
elpa-fsm is:
fsm.el is an exercise in metaprogramming inspired by gen_fsm of Erlang/OTP. It aims to make asynchronous programming in Emacs Lisp easy and fun. By “asynchronous” I mean that long-lasting tasks don’t interfer with normal editing.
Some people say that it would be nice if Emacs Lisp had threads and/or continuations. They are probably right, but there are few things that can’t be made to run in the background using facilities already available: timers, filters and sentinels. As the code can become a bit messy when using such means, with callbacks everywhere and such things, it can be useful to structure the program as a state machine.
In this model, a state machine passes between different “states”, which are actually only different event handler functions. The state machine receives “events” (from timers, filters, user requests, etc) and reacts to them, possibly entering another state, possibly returning a value.
The essential macros/functions are: ;; define-state-machine - create start-FOO function define-state - event handler for each state (required) define-enter-state - called when entering a state (optional) define-fsm - encapsulates the above three (more sugar!) fsm-send - send an event to a state machine fsm-call - send an event and wait for reply
fsm.el is similar to but different from Distel: URL:http://fresh.homeunix.net/~luke/distel/ Emacs’ tq library is a similar idea.
