His monumental tex4ht package (http://ctan.org/pkg/tex4ht) uses it. FILES ===== ProTex.sty -- Basic environment for literate programming AlProTex.sty -- Adjustments to ProTeX README -- Introduction and examples for main features of (Al)ProTeX (this file) MANUAL ====== Eitan Gurari, TeX and LaTeX: Drawing and Literate Programming. McGraw-Hill, 1994. ISBN 0-07-025208-4 / 0-07-911616-7 The dratex package described there is at http://ctan.org/pkg/dratex. Various ProTex examples are in that package's file Examples.tex. Table of Contents ================= A. A Basic Literate Programming Environment B. Other Basic Literate Programming Environments C. Environments for Multi-Module Programs D. Code and Documentation Produced from Same Specification E. Examples B, C, D F. License The code for the examples can be extracted from this file by renaming this file to LitProg.tex and compiling the file with TeX or LaTeX (the Makefiles for Example C, however, must be extracted mannually). The compilation puts the code in files progA.tex, progB.tex, progC.tex, main.tex, aux.tex, macros.tex, progC.sty, and progD.tex. A. A Basic Literate Programming Environment =========================================== \input ProTex.sty \AlProTex{EXT,<<<>>>,title,list,[],`} This environment adds to (La)TeX the following commands for handling code. a. Definitions of code fragments \<code title\><<< code fragment>>> b. References to code segments `<code title`> c. Output files of code \OutputCode[EXTENSION]\<code title\> `[EXTENSION]' is optional when EXTENSION = EXT d. References to the character ` within code fragments `` Warning: Do not use 2 or more consecutive blank characters in `<code title`> ------- Example A: Single-Module C Program ---------------------------------- ------- Put in file progA.tex and compile with LaTeX ------%->>>\<progA\><<<- \documentstyle{book} \input ProTex.sty \AlProTex{c,<<<>>>,title,list,[],`} \begin{document} \<body\><<< printf("\n ``hello everybody``"); >>> \<prog A\><<< `<include`> main() { `<body`> } >>> \<include\><<< #include <stdio.h> >>> \<body\><<< printf("\n"); >>> \OutputCode\<prog A\> \end{document} ------------ End Example A -----------------%->>>\OutputCode\<progA\>\<\><<<- B. Other Basic Literate Programming Environments ================================================ a. Framing of code fragments can be requested with the option [[]] in \AlProTex, e.g., \AlProTex{EXT,<<<>>>,title,list,[],`,[[]]} b. Framing of code titles can be avoided by removing the option [] from \AlProTex, e.g, \AlProTex{EXT,<<<>>>,title,list,`} c. The characters @, |, and ? can also act as escape characters within code fragments (e.g., replace all appearances of ` with @ in Example A). d. Line breaks within listing of code can be obtained with the command `NL% e. Comments within listing of code can be obtained with commands of the form `%...`% f. The choice of code-delimiters <<< and >>> can be changed by placing a command of the form \def\CodeDel{{open delimiter}{close delimiter}} before \AlProTex. g. The following command requests that future \OutputCode commands identify the titles of the different code fragments. (Other information, like page numbers in documents and line numbers in source files, can also be incorporated.) \Comment{open-comment delimiter}{close-comment delimiter} PLEASE EXAMINE AND RUN EXAMPLE B C. Environments for Multi-Module Programs ========================================= Multi-module programs can be divided into independent (La)TeX files that can be compiled either separately or together. For instance, in Example C 1. Three modules (main, aux, and macros) are defined independently (in main.tex, aux.tex, macros.tex) and are connected through a joint root file (progC.tex). The different files import a common style file (progC.sty). progC.tex Root file main.tex LaTeX file for first module aux.tex LaTeX file for second Module macros.tex LaTeX file for third module progC.sty Style file (imported by each of the above files) make files Unix management programs 2. The files can be compiled separately (latex main.tex, latex aux.main, latex macros.tex) or jointly (latex progC.tex). 3. To allow quick generation, compilation, and linkage of C-code files (see, e.g., the make files), joint compilations do not revise code files. 4. Separate compilations use chapter/section/subsection/subsubsection/page numbers that are collected in joint compilations. 5. In joint compilations, each module ends with an index to its code titles. 6. To allow nonrelated identical titles in different modules, and to save on memory, previous definitions of code fragments are deleted at the start of each module. PLEASE RUN AND EXAMINE EXAMPLE C D. Code and Documentation Produced from Same Specification ========================================================== Example D demonstrates how math formulas and their code can be generated from joint specifications.
