I know there are other solutions, but is there an if-then-else or equivalent in Gen's [expr] and [codebox]?

I seem to remember a statement that there was, but now can't find any documentation.

if-then-else-expression-in-expr-and-codebox

have a look here, the same applies to expr inside gen:

about codebox, i haven't tried yet but i understood it takes C code so i guess if/then/else statements should work:

no, codebox doesn't take if, then, else, for, etc. but apparently it will one day.

codebox is not C. it just feels a little like it. but it is very very simple and easier than javascript or lua.

in gen and codebox i assign first and use [switch]:

or [selector] or [gate] (same as max land).

in gen and codebox i assign first and use [switch]:
x = w ? y : z;

I was sitting with a similar problem the last days, missing if-else, it looks like there is an example of how to get around it,using ? operator within codebox,, needing extra lines of code, intermittent variables

a bit down the page, porting c code to gen, >>stkr<< writes himself : (looks ridiculous - getting around GenExpr limitations)

its about pd filters realized in gen

Well, [gen~] is a synchronous language. Just because it has a C-like syntax...

Someone could prove me wrong, but I think it has to do with preserving state across time spent in the rendering loop. Currently with [gen~] everything is forgotten when the audio interrupt is exited. There are exceptions at the object level, like [sah].

But if conditionals have got your nose twisted, try anything that changes the flow of time, like a "for" or "while" loop!

greetings and just IF more people follow this if-else ? discussion THEN this tiny simple example is working, its doing C*sin(x) where C is variable parameter and x is fed back in the loop and trig is a running sample counter input, so that there will only be a new output every so many samples.

here on my babysocks in the code landscapes i hope that in this way there is some some cpu saving in the sense that the csinx calculation is only done IF trig==1.. for more complex algorithms this would matter i bet.

x = in1;
c = in2;
trig = in3;
xout = (trig == 1) ? c * (sin (x)) : x;
out1 = xout;
