Emulator

I accidentally clicked on Create instead of preview.

If you assign a button this:

A & B | D & F

Dolphin will interpret it like this:

(((A & S) | D) & F)

instead of

((A & S) | (D & F))

The Problem is present in the latest stable version. Currently most recent version is 5.0-7936

Screwed up again.

What i actually wanted to say is:

If you make a button assignment like this:

A & B | C & D

Dolphin will interpret it like this:

(((A & B) | C) & D)

instead of

((A & B) | (C & D))

Have you considered parenthesizing your expressions appropriately? Even in C or C++, not doing that would cause a -Wparenthesis warning for precisely that reason (ambiguous precedence). Coincidentally, that associativity in the example you give is also that of C/C++ (left-associative).

I know that I can use parentheses to make it do whatever I want. I just think that most people expect it to use the order of operation of predicate logic (i.e. First ! then ∧ and then ∨) and that making it use that order would prevent a lot of confusion. The whole issue is really about usability and not about something not working.

Note that by changing that at this point would potentially break perfectly functioning existing expressions that already exist that users currently have. Because of that, I don't think it would be wise to change it over. I'm somewhat skeptical of usability issues really being massive here (not saying they're non-existent), given this is the first issue I've seen about the matter in 6 years (that is to say, the first one I've seen about it since working on the project).
