021 build requires basic

✓ Passing This code compiles and runs correctly.

Code

// Test 619: Basic build.requires
// Validates that std/compiler:requires captures build dependencies using implicit Source blocks
//
// This test demonstrates:
// 1. Implicit Source blocks: { zig_code } instead of source: "zig_code"
// 2. AST collection: Compiler walks AST to find std/compiler:requires
// 3. Zero boilerplate: just declare requirements, build.zig generated automatically

~import std/compiler

// Declare build dependencies using implicit Source blocks
// The { } block is compiled to a Source parameter containing raw Zig code
// The compiler's CompilerRequiresCollector walks the AST and collects these
~std/compiler:requires {
    exe.linkSystemLibrary("sqlite3");
}

~std/compiler:requires {
    exe.linkSystemLibrary("zlib");
}

~std/compiler:requires {
    exe.addIncludePath(b.path("vendor/include"));
}
