Recommended way to configure GPIO buttons-to-commands

[caver01]

I am wondering if someone can recommend the best/easiest method for configuring GPIO-triggered commands. I used to run mholgatem's excellent GPIOneer but compatibility with the Jessie image has held back recent updates. As such, I am looking for an alternative that meets the following requirements:

1. Loads at startup.
2. Adjustable/Configurable PIN# to ground triggers (buttons) and OK if it requires editing a config file.
3. GPIO button press can issue a keyboard keystroke.
4. GPIO button press can alternatively issue a complete command (i.e. shutown, or volumne up/down, etc.--whatever I specify in a config)
5. Compatible with RetroPie
6. A somewhat straightforward install and setup (as opposed to, "Just build a python script!")

I know there are a few options, including writing my own python scripts, which I could create someday as I gain more experience, but I figured some of you might be willing to share your experience with what you may already be using.

One note: I did setup a BASH script that launches at startup following this thread so I do have a soft shutdown (and startup on PIN3) working, but this solution doesn't really scale easily, and there is a delay that requires me to hold down the button for it to register. I expect a python solution is better suited to this situation.

HI ! Really sorry for hijacking this thread with my own question but I never managed to get an answer :) Does using GPIO reduce input delay compared to USB controllers/keyboards, in emulators ? (yes, there is always a slight input delay ;)

Why are you hijacking? I don't mind adding additional content to this, but if you already asked this question somewhere, why didn't you continue the conversation with whomever responded?
