Article contents:== Outdated egg! This is an egg for CHICKEN 4, the unsupported old release. You're almost certainly looking for [[/eggref/5/inline|the CHICKEN 5 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-5.html|egg index]]. Otherwise, please consider porting this egg to the current version of CHICKEN. [[tags: egg]] == inline [[toc:]] === Description Allows compiled C inside interpreter scripts. === Author [[/users/felix winkelmann|felix winkelmann]] === Requirements * [[bind]] * [[simple-sha1]] === Documentation This extension library provides a simple macro for using C code in the Chicken interpreter ({{csi}}). The program text is embedded into a thin Scheme wrapper and compiled on the fly into a dynamically loadable library. A local directory caches the compiled code and subsequent definitions of the same source text will load the already compiled library from the cache. Callbacks back into Scheme are not supported. <macro>(inline STRING [OPTIONS])</macro> Expands into a call of {{inline-compile}} and compiles the code given in {{STRING}}. If encountered in compiled code, then this form will directly expand into a {{(bind* ...)}} form, effectively embedding the inline code in the compiled file (so no run-time compilation is needed). The optional string argument {{OPTIONS}} may contain additional compilation parameters (these are ignored, when {{inline}} is used in compiled code). <enscript highlight="scheme"> (inline "int foo(int n) { return(n * 2); }") ==> (inline-compile "int foo(int n) { return(n * 2); }") ; when interpreted ==> (bind* ; when compiled "int foo(int n) { return(n * 2); }") </enscript> <procedure>(inline-compile STRING [OPTIONS])</procedure> Compiles the C source code in {{STRING}} dynamically. If a compiled library with the same source text is currently loaded (and has been cached), then nothing is done. If it is not loaded, the ''inline cache'' is consulted, whether a compiled file for the same text is stored, and, if it is, it's loaded and the procedure is returned. If no such file exists, the compiler (``csc'') is invoked to create a compiled library (with any extra options passed in {{OPTIONS}}), which is stored in the cache. The code will be compiled as if wrapped in {{#>! ... <#}}. Note that you will have to shield {{#include}} forms, if you don't want them to be processed by the FFI parser: <enscript highlight="scheme"> (inline #<<EOF #ifndef CHICKEN #include "gd.h" #include <stdio.h> #endif void genimages(int w, int h) { gdImagePtr im; FILE *pngout, *jpegout; int black; int white; im = gdImageCreate(w, h); black = gdImageColorAllocate(im, 0, 0, 0); white = gdImageColorAllocate(im, 255, 255, 255); gdImageLine(im, 0, 0, w - 1, h - 1, white); pngout = fopen("test.png", "wb"); jpegout = fopen("test.jpg", "wb"); gdImagePng(im, pngout); gdImageJpeg(im, jpegout, -1); fclose(pngout); fclose(jpegout); gdImageDestroy(im); } EOF "-L -lgd -L -lpng -L -lz -L -ljpeg -L -lfreetype" ) (genimages 64 64) </enscript> <parameter>inline-cache</parameter> Holds the name of the directory which is used as a cache for compiled code and defaults to {{./.cache}}. === Changelog * 1.9 use simple-sha1 instead of md5 to reduce number of dependencies * 1.7 md5-digest use replaced [Kon Lovett] * 1.6 ported to CHICKEN 4 [felix] * 1.5 Fixed dependencies on new easyffi egg * 1.4 Fixed dependency on {{utils}} unit [Thanks to Benedikt Rosenau] * 1.3 {{inline-support}} wasn't installed properly [Thanks to Peter Wang] * 1.2 Adapted to new setup scheme * 1.1 Now uses easyffi stuff, which is much simpler and more powerful. Does the right thing when compiled. * 1.0 Initial release === License Copyright (c) 2003-2007, Felix L. Winkelmann All rights reserved.
