Macros expression

Learn Macros expression in Haxe through the exact construct, a dedicated example, a boundary case, and a mastery check.

12 min read • Advanced

Macros expression is an atomic Haxe lesson inside Metaprogramming & Targets. The example uses the specific syntax, command, API, instruction, or language rule named by this lesson.

Study the construct itself, then change one relevant input and predict the result before running it. That keeps this lesson focused on Macros expression rather than on generic Haxe syntax.

Topic-specific example

haxe-07-06.hx
haxe Try It Live 
import haxe.macro.Expr; class M { public static macro function answer():Expr return macro 42; }
Edge case / engineering note

Compile Macros expression for at least one target and watch for target-specific behavior where the feature crosses a platform boundary.
