From the paper:<p>> We describe a system, 'ExplainThis', that automatically generates contextualized language documentation, structured based on our study of language documentation but specialized to the particular code at the cursor.<p>> This system is integrated into the structure editor of Hazel (<a href="https://hazel.org/" rel="nofollow noreferrer">https://hazel.org/</a>), a live functional environment.<p>----<p>> Potential use cases of 'ExplainThis' include code reading and comprehension (e.g. a user trying to understand existing functions in a library or examples in instructor-created tutorials); writing new code (e.g. a user trying to modify starter code to complete an assignment); or debugging (e.g. a user trying to understand unexpected behavior of a function).
