# checklistings

User manuals and papers about programming languages usually contain many code samples, often with accompanying compiler messages giving the types of declarations or error messages explaining why certain declarations are invalid.

The checklistings package augments the fancyvrb and listings packages for including source code in documents with a way to pass the source code through a compiler and also include the resulting messages in the document.

The motivation is to check the code samples in a document for syntax and typing errors and to facilitate the inclusion of inferred types and compiler warnings or errors in a text. This package is intentionally very lightweight and unlike packages like python it is not intended for interacting with an interpretor or including the execution traces of code. While checklistings does not focus on a specific programming language, it is designed to work well with ML-like languages.

Using the package involves three elements:

1. The declaration \usepackage{checklistings}.
2. The verbatim environment \begin{chklisting}...\end{chklisting}.
3. The shell script checklistings.sh.

In a first pass, latex/pdflatex outputs code samples into files. The second pass is performed by checklistings.sh which passes each file through a compiler to generate corresponding output files. In a third pass, latex/pdflatex reads from the generated files to incorporate the results into the document.

A checklistings.hva file is provided for interoperability with HeVeA.

Please send comments, suggestions, and bug reports (with version number and the keyword "checklistings" in the subject of the message) to <tim@tbrk.org>. Please keep in mind that we prefer to keep checklistings simple and lightweight rather than to incorporate many different configuration and customization options. The source code is hosted on GitHub.

This package was developed within the PARKAS at Inria and the ENS.
