R7RS Home Page
This is the home page for R7RS, the Revised⁷ Report on the Algorithmic Language Scheme. This version of Scheme has been divided into a small language, suitable for educators, researchers, and users of embedded languages; and a large language focused on the practical needs of mainstream software development.
The report on the small language was finalized on July 6, 2013. It is available in PDF format and as LaTeX source code. There are errata.
A frozen copy of the Red Edition ballot is available at RedEditionBallot. The results, which are now final, can be seen at http://tinyurl.com/wg2-red-results. The actual report is not yet available.
For R7RS-small implementations, see ImplementationSupport.
For R7RS benchmarks on many Schemes, see this graphic. Some adjustments were made to accommodate the differences between Schemes. The source is here.
