Contextualized programming language documentation (2022) [pdf]

From the paper:

> 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.

> This system is integrated into the structure editor of Hazel (https://hazel.org/), a live functional environment.

----

> 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).
