R7RS small
The teaching and portability baseline for this site: libraries, records, exceptions, bytevectors, parameters, and a compact standard library set.
Standards
R7RS first, with the rest of Scheme in context.
The R7RS small report is the default authority for examples on r7.rs. R5RS, R6RS, and SRFI remain essential for understanding Scheme culture, portability, and library practice.
Read First
R6RS
Important for understanding Scheme's larger standardization path, library design, conditions, Unicode, records, and syntax-case.
R5RS
The classic compact report belongs primarily at r5.rs, but remains necessary background for older code and many courses.
SRFI
Scheme Requests for Implementation document portable libraries, features, and conventions beyond the base reports.
How r7.rs Uses Standards
- Portable examplesMust run using R7RS small facilities unless the page explicitly names required SRFIs or implementation extensions.
- Report citationsReference pages should point to R7RS sections such as expressions, libraries, macros, records, standard procedures, and feature identifiers.
- R6RS comparisonUse R6RS to explain design alternatives, not as the default dialect for course code.
- R5RS historyUse r5.rs for deeper classic Scheme history, SICP-era materials, and early reports.
