Eval a String and transform it to macro expression

[Francis Bourre]

Hi everyone,

this is the code that I would like to produce inside my final expression:

var o = a.b.c.d;

But I can't figure out a way without generating each step inside a merged block with a loop:

var s0 = a;

var s1 = s0.b;

var s2 = s1.c;

var o = s2.d;

I'm searching for the optimized way to write it directly in one expression:

var o = a.b.c.d;

It's important to mention that I can't predict String source value in advance.

Thank you so much in advance guys for your lights. :)

Not really sure what your input looks like, but $p might be what you're after: http://haxe.org/manual/macro-reification-expression.html

Example:

var string = "a.b.c.d";

var expr = macro var o = $p{string.pop(".")};

For arbitrary expressions, you may want to try this: http://api.haxe.org/haxe/macro/Context.html#parse

Best,

Juraj

Thank you so much, it works like a charm.

var expr = macro var o = $p{string.split(".")};
