Function isSdkInstalled [src]

Check if SDK is installed on Darwin without triggering CLT installation popup window. Note: simply invoking xcrun will inevitably trigger the CLT installation popup. Therefore, we resort to invoking xcode-select --print-path and checking if the status is nonzero. stderr from xcode-select is ignored. If error.OutOfMemory occurs in Allocator, this function returns null.

Prototype

pub fn isSdkInstalled(allocator: Allocator) bool

Parameters

allocator: Allocator

Source

  pub fn isSdkInstalled(allocator: Allocator) bool {
    const result = std.process.Child.run(.{
        .allocator = allocator,
        .argv = &.{ "xcode-select", "--print-path" },
    }) catch return false;

    defer {
        allocator.free(result.stderr);
        allocator.free(result.stdout);
    }

    return switch (result.term) {
        .Exited => |code| if (code == 0) result.stdout.len > 0 else false,
        else => false,
    };
}
