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.
A concise definition of the first partial edition of R7RS-large, known as the Red Edition, is now available. It is a frozen copy of the Red Edition ballot plus the names of the libraries, which were passed by unanimous consent. The results, which are now final, can be seen at http://tinyurl.com/wg2-red-results. A single physical document is in preparation.
For R7RS-small implementations, see ImplementationSupport. Larceny includes all the SRFIs of the Red Edition, though they are not yet available under their standardized names. Other implementations will hopefully follow.
