10.16 srfi-55 - Requiring extensions

Module: srfi-55

This module defines require-extension macro, a yet another way to write portable scripts. See srfi-0 - Feature conditional and srfi-7 - Feature-based program configuration language for other means of ensuring specific features.

This module is autoloaded when you use require-extension, so you don't need explicitly say (use srfi-55); for portable scripts, you shouldn't.

Macro: require-extension clause …

Make extension(s) specified by clauses available in the rest of the program.

A clause takes the following form:

(extension-id extension-arg …)

Currently, only srfi is supported as extension-id, and its arguments are SRFI numbers.

For example, the following form:

(require-extension (srfi 1 13 14))

Roughly correspons to Gauche's use forms:

(use srfi-1) (use srfi-13) (use srfi-14)
