Nested function calls

[klkvsk]

When using custom functions, it would be great to be able to nest them like so: {func1 "foo" (func2 "bar")} And this would be rendered as: <?= func1("foo", func2("bar")); ?> Is this possible?

It's possible. Is it really so necessary?

Real world example: I define a custom function for localizing strings: $fenom->addFunctionSmart("i", "Localizer::translate"), so I can write in template {i "Hello"}. Then I define another function, that somehow decorates a string, and want to pass my localized string into it, I would want to write something like: {widget (i "Hello") }. But I cant. There are workarounds, of course, but they're not as readable as this.

Also, I found out that top-level functions are available in template. But if they used as arguments, they compile, but do not work. With {i strtoupper("foo")} "i" would still get "foo" as argument. Looks like a bug. And since calling of top-level user-defined functions is available, maybe also add support for calling static methods?

You may use modifiers: $fenom->addModifier('i', "Localizer::translate") and then use it {widget "Hello"|i } or {i "foo"|up}

But i planned this feature. First need analyze, may be some ninja-bugs or conflicts with the lexer. I thought about static methods in templates, it is good idea to have can use {Fenom\TestCase::dots("string")}. Also need add security option for disable call static methods.

P.S. i test bug {i strtoupper("foo")}

Use modifiers
