Query: What Do Developers Discuss about Code Comments?   Code comments are important for program comprehension, development, and
maintenance tasks. Given the varying standards for code comments, and their
unstructured or semi-structured nature, developers get easily confused
(especially novice developers) about which convention(s) to follow, or what
tools to use while writing code documentation. Thus, they post related
questions on external online sources to seek better commenting practices. In
this paper, we analyze code comment discussions on online sources such as Stack
Overflow (SO) and Quora to shed some light on the questions developers ask
about commenting practices. We apply Latent Dirichlet Allocation (LDA) to
identify emerging topics concerning code comments. Then we manually analyze a
statistically significant sample set of posts to derive a taxonomy that
provides an overview of the developer questions about commenting practices. Our
results highlight that on SO nearly 40% of the questions mention how to write
or process comments in documentation tools and environments, and nearly 20% of
the questions are about potential limitations and possibilities of
documentation tools to add automatically and consistently more information in
comments. On the other hand, on Quora, developer questions focus more on
background information (35% of the questions) or asking opinions (16% of the
questions) about code comments. We found that (i) not all aspects of comments
are covered in coding style guidelines, e.g., how to add a specific type of
information, (ii) developers need support in learning the syntax and format
conventions to add various types of information in comments, and (iii)
developers are interested in various automated strategies for comments such as
detection of bad comments, or verify comment style automatically, but lack tool
support to do that.
