| jgaz | Apparently the precedence of = is too loose for the ?? ternary operator? Why is that? I was able to "fix" it with `<test> ?? ($foo = val) !! ($bar = val)`, but I'm not sure that's optimal either. | 18:42 | |
| nemokosch | isn't that the normal way? I can't think of a language where you'd need to write variable = (condition ? aValue : bValue), with the parens | 18:44 | |
| jgaz | I don't think I have to do that in Perl, I can check... | ||
| nemokosch | the ternary operator is not for side effects, after all | 18:46 | |
| the true irony is, though, that your example can be rewritten without parens, if you want to golf it so badly: | 18:48 | ||
| jgaz | Okay, so I can make it work, but the precidence is wrong if I have an equals. It silently fails to do the right thing. | ||
| nemokosch | <test> ?? $foo !! $bar = val | ||
| jgaz | Silent failure is Perl 5. | 18:49 | |
| hmm... okay. | |||
| nemokosch | I would say it looks weird but it seems to do the "set one of the variables to val, depending on the test" thing | ||
| jgaz | I will say, at least Raku gives me a warning that there is a precidence issue. | 18:52 | |
| IDK if it's code golf exactly, but yeah, I like to do as much as I can on one line as reasonably possible. | 18:53 | ||
| This is especially true on a return line. | |||
| nemokosch | If you are okay with repeating val, I'd definitely prefer an if-else | 18:55 | |
| if not, then maybe (<test> ?? $foo !! $bar) = val, with the parens for readability | |||
| jgaz | Hmm... I'll play with that. | 18:57 | |
