rivt is an open source software project for writing engineering documents. Documents are generated from rivt files that produce formatted text, HTML and PDF documents.
A rivt file is a Python file (.py) that imports the rivtlib Python package and implements an API that interprets rivt markup and reStructuredText. A rivt file can publish a document in any format.
A published document is referred to as a rivt doc. A collection of rivt docs may be collated into a rivt report. This site is an example of a report.
As an open source project rivt may be integrated with other programs, and rivt files may be shared and cooperatively improved. An integrated rivt framework is described here..
Small rivt file examples are provided here and here. An interface for searching rivt files on GitHub is here.
