REBOL [ Title: "MakeDoc 2 - The REBOL Standard Document Formatter" Version: 2.5.7 Copyright: "REBOL Technologies 1999-2005" Author: "Carl Sassenrath" File: %makedoc2.r Date: 10-Mar-2007 ;10-Jan-2005 Purpose: { This is the official MakeDoc document formatter that is used by REBOL Technologies for all documentation. It is the fastest and easiest way to create good looking documentation using any text editor (even ones that do not auto-wrap text). It creates titles, headings, contents, bullets, numbered lists, indented examples, note blocks, and more. For documentation, notes, and other info visit http://www.rebol.net/docs/makedoc.html } Usage: { Create a text document in any editor. Separate each paragraph with a blank line. Run this script and provide your text file. The output file will be the same name with .html following it. If you use REBOL/View the output file will be displayed in your web browser as well. You can also call this script from other scripts (e.g. CGI). These are supported: do %makedoc2.r do/args %makedoc2.r %document.txt do/args %makedoc2.r 'load-only doc: scan-doc read %file.txt set [title out] gen-html/options doc [(options)] write %out.html out } Library: [ level: 'intermediate platform: 'all type: [tool] domain: [html cgi markup] tested-under: none support: none license: 'BSD see-also: none ] ] ; Below you can specify an HTML output template to use for all your docs. ; See the default-template example below as a starting suggestion. template-file: %template.html ; Example: %template.html ; There are three parts to this script: ; 1. The document input scanner. ; 2. The document output formatter (for HTML). ; 3. The code that deals with input and output files. *scanner*: context [ ;-- Debugging: verbose: off debug: func [data] [if verbose [print data]] ;-- Module Variables: text: none para: none code: none title: none left-flag: off opts: [] ;[no-toc no-nums] out: [] ; The output block (static, reused) option: none ;--- Parser rules for the Makedoc text language (top-down): rules: [some commands] commands: [ newline here: (debug ["---PARSE:" copy/part here find here newline]) ;-- Document sections: | ["===" | "-1-"] text-line (emit-section 1) | ["---" | "-2-"] text-line (emit-section 2) | ["+++" | "-3-"] text-line (emit-section 3) | ["..." | "-4-"] text-line (emit-section 4) | "###" to end (emit end none) ; allows notes, comments to follow ;-- Common commands: | #"*" [ [">>" | "**"] text-block (emit bullet3 para) | [">" | "*" ] text-block (emit bullet2 para) | text-block (emit bullet para) ] | #"#" [ ">>" text-block (emit enum3 para) | ">" text-block (emit enum2 para) | text-block (emit enum para) ] | #":" define opt newline (emit define reduce [text para]) ; ">>" reserved ; "<<" reserved ;-- Enter a special section: | #"\" [ "in" (emit indent-in none) | "note" text-line (emit note-in text) | "table" text-line (emit table-in text) | "group" (emit group-in none) | "center" (emit center-in none) | "column" (emit column-in none) ] ;-- Exit a special section: | #"/" [ "in" (emit indent-out none) | "note" (emit note-out none) | "table" (emit table-out none) | "group" (emit group-out none) | "center" (emit center-out none) | "column" (emit column-out none) ] ;-- Extended commands (all begin with "="): | #";" text-block ; comments and hidden paragraphs | #"=" [ #"=" output (emit output trim/auto code) | "image" image | "row" (emit table-row none) | "column" (emit column none) ; (for doc, not tables) | "options" [ any [ spaces copy option [ "toc" | "nums" | "indent" | "no-indent" | "no-toc" | "no-nums" | "no-template" | "no-title" | "old-tags" | "root-images" ] (append opts to-word option) ] ] | "template" some-chars (repend opts ['template as-file text]) ] ;-- Primary implied paragraph types: | example (emit code trim/auto detab code) | paragraph ( either title [emit para para][emit title title: para] ) | skip (debug "???WARN: Unrecognized") ] space: charset " ^-" nochar: charset " ^-^/" chars: complement nochar spaces: [any space] some-chars: [some space copy text some chars] text-line: [any space copy text thru newline] text-block: [any space paragraph opt newline] ; ignore leading space, extra NL !??? paragraph: [copy para some [chars thru newline]] example: [copy code some [indented | some newline indented]] indented: [some space chars thru newline] output: [ some space copy code thru newline any ["==" ["^-" | " "] copy text thru newline (append code text)] ] define: [copy text to " -" 2 skip text-block] image: [ left? any space copy text some chars ( if text/1 = #"%" [remove text] ; remove %file text: as-file text emit image reduce [text pick [left center] left-flag] ) ] left?: [some space "left" (left-flag: on) | none (left-flag: off)] as-file: func [str] [to-file trim str] ;-- Output emitters: emit: func ['word data] [ debug ["===EMIT: " word] if block? word [word: do word] ;???? if string? data [trim/tail data] repend out [word data] ] emit-section: func [num] [ emit [to-word join "sect" num] text title: true ] ;-- Export function to scan doc.
