Article contents:== Outdated egg! This is an egg for CHICKEN 3, the unsupported old release. You're almost certainly looking for [[/eggref/4/simple-macros|the CHICKEN 4 version of this egg]], if it exists. If it does not exist, there may be equivalent functionality provided by another egg; have a look at the [[https://wiki.call-cc.org/chicken-projects/egg-index-4.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. [[tags: egg]] == simple-macros [[toc:]] === Description <nowiki>Andr&eacute;</nowiki> van Tonders macro and module system. '''Note:''' This extension is currently unsupported. A new version has been released and the maintenance status is unclear. === Author <nowiki>Andr&eacute;</nowiki> van Tonder === Requirements None === Download [[http://code.call-cc.org/legacy-eggs/3/simple-macros.egg|simple-macros.egg]] === Documentation This is a port of the ``simple-macros'' macro and module system by <nowiki>Andr&eacute;</nowiki> van Tonder. For detailed specifications consult the official SRFI documents: * [[http://srfi.schemers.org/srfi-72/srfi-72.html|SRFI-72]] * [[http://www.het.brown.edu/people/andre/macros/srfi-module.htm|Portable modules]] ==== CHICKEN specific notes At least CHICKEN version 2.110 is required "Curried" {{define}} is allowed, as are definitions of the form {{(define VARIABLE)}}. Note that DSSSL extended lambda lists are currently not available. CHICKEN as of version 2.0 supports the abbreviation {{#`}} for {{quasisyntax}}. {{eval-when}} is not available Internal {{define-values}} is not supported The following modules are provided: ; chicken : All non-standard procedures available in CHICKEN (that is, in the {{library}} and {{eval}} library units). ; chicken-internals : Internally used definitions - you normally don't use this module directly. ; chicken-ffi : Macros for interfacing to foreign code. ; chicken-macros : Non-standard syntax extensions * extras * lolevel * posix * regex * srfi-1 * srfi-4 * srfi-13 * srfi-14 * srfi-18 * tinyclos * utils Modules with the non-standard extensions provided in separate library units of the core CHICKEN distribution. The {{tinyclos}} module exports the {{define-class}}, {{define-generic}} and {{define-method}} syntax. Methods may only be defined on generic functions that have been previously defined with {{define-generic}}. * matcher * syntax-case Additional syntax modules for pattern matching and {{syntax-case}}. The latter also defines {{syntax-rules}}. To load these modules into your environment, use the {{require-module}} form (see below), with the string "-module" added to the name: (require-module posix-module) Toplevel expressions are by default evaluated in a scope that has the {{scheme}} and {{chicken}} modules imported. Note that module definitions by default only import the bindings of the {{scheme}} module. To load modules into the compile-time/run-time environment, use this special form: (require-module MODULENAME) Loading/linking of separately compiled modules and importing their definitions is strictly separated. To use a separately compiled module, first load it via {{(require-module ...)}}, then import it. If you need to create a module for pre-existing libraries, create a wrapper module. The special form {{import-primitives}} or {{import-primitives-for-all}} allows importing unqualified toplevel identifiers into the current scope: <enscript highlight=scheme> ;;; my-stuff-module.scm ;; add code here to define, include or require the definition of `my-print' ... (module my-stuff (my-print) ; exported identifiers (import-primitives my-print) ) </enscript> If you compile this file into a shared library, you can load the module by invoking (require-module my-stuff) and import it's definitions via (import my-stuff) Extensions: <macro>(define-for-syntax ...)</macro> Identical to {{(begin-for-syntax (define ...))}}. This extension is still in an experimental stadium. === Changelog * 2.12 Added {{define-for-syntax}} * 2.11 Added missing {{hash-table-ref/default}} to {{extras-module}} * 2.1 Adapted to current official version * 2.01 Added implementation of {{import-primitives}} by <nowiki>Andr&eacute;</nowiki> van Tonder * 2.0 Ported to new version; various improvements * 0.9.5 Added documentation to egg; fixed bugs in {{define-macro}} and {{include}} * 0.9.4 Added {{rec}} (SRFI-31), removed {{hash-table-count}} (frome extras module) * 0.9.3 Several fixes by Dale Jordan * 0.9.2 {{regex}} and {{posix}} modules were not built, changed {{define-primitive-module}} to work on systems where libffi isn't used (i.e. works around argument limit) [Thanks to Dale Jordan] * 0.9.1 === License Copyright (C) Andre van Tonder (2005).
