11 Library modules - SRFIs

This chapter lists modules that provides SRFI functionalities. Note that some of SRFI features are built in Gauche core and not listed here. The SRFIs that have been adopted to R7RS-large are described in Library modules - R7RS standard libraries.

See Standard conformance, for entire list of supported SRFIs.

(Even if a srfi is not listed here, you can still say (use srfi.N) or (import (srfi N)), as far as srfi N is supported by Gauche.)

Note that we use a hyphen to refer to a SRFI as a specification (e.g. SRFI-13) but use a hierarchical name for the module (e.g. srfi.13 as a Gauche’s module, or (srfi 13) as a R7RS library).
