NL2Scratch: An Executable Benchmark and Evaluation for Block-Based Programming

arXiv:2606.22061v1 Announce Type: cross Abstract: Block-based programming environments such as Scratch are widely used in early programming education, yet natural-language-to-code (NL2Code) research has focused primarily on text-based languages. Scratch programs are event-driven, visually compositional, and distributed across concurrent scripts, making conventional NL2Code assumptions and evaluation insufficient. We introduce NL2Scratch, an executable benchmark for natural-language-to-Scratch ge
