Abstract

Blockly is a visual programming editor by Google, being open-source multi-platform and multi-language, while offering jigsaw-style program blocks. It is very popular and currently adopted by an increasing number of visual development solutions. However, as with similar earlier tools, it lacks a full-scale debugger. We present a complete visual debugger for Blockly, working over blocks, supporting the full range of debugging features as with typical source-level debuggers. To support all tracing functions we make no amendments to the underlying JavaScript engine, supporting all debugging operations through code instrumentation inserting invocations to a busy-wait debugger service loop. The latter affects only the source code that is output by Blockly.
