alias with if

[juvannx]

I'm building my device with the buffer described in this issue.
I'd like to recreate commands similar to the old bus pirate to turn the target's power on and off.
I'd like to detect whether the target is already powered by reading the status of a GPIO and, if not, set another GPIO to HIGH, which turns the target's power on, of course using PMOS and NMOS.
In practice, the alias commands should contain an mode dio || if read GPIOX == LOW then set GPIOY H.
Is it possible to do this or is it possible to implement it?
I know I can develop an external script using Python that can certainly do this easily, but I liked the idea of ​​having it already inside the firmware.

Thanks for the suggestions.

I'm building my device with the buffer described in #53 issue.

Well, since the issue was written, the schematic as evolved. You'd better look here for an updated project.

Thank you for your suggestion, I would have liked something more automatic.
I'm not an electronics engineer, but couldn't a comparator automatically switch between the voltages?
Furthermore, couldn't the VCCA/B on the opposite side of the ESP32 on the TXS be disabled if the voltage is external?
That's why I wanted to do something using the Bus Pirate commands.

Currently, it's not possible to add conditions to aliases

Not all commands return a logical false/true state. So it would be complicated to implement it globally for all commands

The simplest solution in this case could be to use a specific syntax to read to add condition management:

read 1 ? set 2 L : set 3 H
read 1 ? set 2 L

and then you can alias this read cmd to poweron
