Pre/Post build and Pre/Post upload steps

[brailovskii]

I think it would be useful feature. Most of the IDEs have these options.
I wrote some usage ideas in parentheses, but these may be extended.

Pre build step ==> run user defined script before building sketch
Post build step ==> run user defined script after building sketch(maybe converting generated binary file to HEX, or encrypting or smth. Else)

Pre upload step ==> run user defined script before uploading to board(initialize board, set it to boot loader mode; or even use user defined uploader)
Post upload step ==> run user defined script after uploading to board(prepare board to exit from boot loader mode)

you can have this (and a lot more) with sloeber
but, to be honest, I am not sure about the pre/post upload steps...

Hi @brailovskii
You can already do this as Arduino IDE provides a way to (re-)define the platform.txt by creating a platform.local.txt:
https://arduino.github.io/arduino-cli/0.21/platform-specification/#platformlocaltxt

In this file simply define your own pre/post target:
