Ternary operators

[iamwizzdom]

Please implement support for ternary operators such as $foo ?: null, $foo?->prop, $foo ? $var1 : $var2
These ternary operators are very helpful in simplifying code. Thanks in advance ☺️

bump - I want this too for templates. Example with "elvis" operator

{if $myvar}{$myvar}{else}N/A{/if}

could be simplified to

{$myvar?:'N/A'}

Thx

Can't this already be done with "default"?`{$myvar|default:"foobar"}`On Apr 30, 2023 7:05 AM, tpneumat ***@***.***> wrote: bump - I want this too for templates.

I suppose so, still that's a longer syntax. But what if you wanted to do this?
{$myvar?'was set':'not set'}

That has to be done with an "if, else, end if" far as I am aware.
{if $myvar}was set{else}not set{/if}

Funny thing is that Smarty supports the ternary since 2009/2010. But it was never documented. Also, it requires the testing expression to be in parentheses. So this should work:

{($foo) ? $var1 : $var2}

But this will not:

{$foo ? $var1 : $var2}

There is no support for the shorthand ?: version. Nor for the null coalescing operator ??. We could try improving support (and docs) for the ternary and maybe also try supporting the null coalescing operator.

See: #881 and #882.

can confirm it works

Ternary support is implemented in v5

Thank you!
