dMZX Forums: Ternary Operator -> Archived Requests -> Tracker

Originally suggested by: NovaYoshi. I somewhat agree though, because I find myself making a lot of faux-ternary-operator constructs.

set "LOCAL" "('broseph'>0 ? 'beez'*('hello'?2:1) : 99)"

Basically, if the current value when the ? operator is reached is equal to 0, the expression discards everything up to the last : in the current focus. Otherwise, it discards everything between the ? and the next ? or : in the current focus, to prevent things from breaking when someone uses the thing improperly. If there's no : or nothing on the other side of :, it returns 0. If there's nothing between ? and :, it returns the result of the condition or 0 depending on what's favored.

I approve.

I approve assuming you plan to implement it in both the regular and debytecode expression parser paths.

I personally would vote not to follow C here and assume invalid (0) if both sides of the : aren't provided. In C if you do a = b ? b : c; the 'b' might be evaluated twice if it is an expression itself. However, in C, with the a = b ?: c; form, b is evaluated only once.

Updating version to: 2.85

Yes, I intend to implement this for both regular and debytecode. I'll wait for 2.85 to implement it, but I don't think a version check is necessary in this case.

Updating status to: Implemented
Issue fixed in: GIT

Implemented in GIT a0b1faa for both regular and debytecode MZX.

Fixed a bug where this broke c?? and p?? in debytecode in GIT 85b8add.
