Code

// Test 210_046: Implicit Expression with Semicolon
// Validates that semicolons inside an Expression parameter are captured as
// part of the opaque text — NOT treated as parser-level separators.
//
// Background: when a DSL author wants multi-part call-site syntax for a
// keyword-like Expression, the convention is to use ';' inside the Expression
// (which the parser captures verbatim), letting ',' remain available as the
// parser-level argument separator. The parser is hypothesised to treat
// implicit Expression as opaque text, splitting only on top-level commas with
// brace/paren counting. This test confirms that hypothesis.

const std = @import("std");

~[comptime|transform]event make-kiss { expr: Expression, program: *const Program, allocator: std.mem.Allocator } -> *const Program

~proc make-kiss|zig {
    std.debug.print("Captured: '{s}'\n", .{expr});
    return program;
}

// Case 1: single positional Expression containing a semicolon.
// No top-level comma => one arg => entire text captured verbatim.
~make-kiss(Claude -> Codex; because why not)

// Case 2: multi-part DSL using ';' as the in-Expression separator.
~make-kiss(a -> b; c -> d; e -> f)

// Case 3: nested parens with commas inside, semicolons at the top of the
// Expression. Inner commas must be ignored (brace-counting); outer semicolons
// are captured verbatim.
~make-kiss(foo(x, y); bar(p, q))
