REBOL [ Title: "REBOL Standard Document Formatter" Date: 25-May-2001 Version: 0.9.0 File: %make-doc.r Author: "Carl Sassenrath" Purpose: {(See MakeDoc2 for the latest version.) Converts very simple text file format into other document formats (such as HTML) with good titles, table of contents, section headers, indented fixed-spaced examples, bullets and definitons. Does the formatting so you can focus on the hard part: the words. } Email: %carl--rebol--com Note: { ^-^-The input file scanner and the output format generator ^-^-are now independent. The input file is scanned into ^-^-an internal block that can be used to generate different ^-^-target output formats such as HTML, text, PDF, helpfile, ^-^-etc. Only HTML generator is provided at this time. ^-} library: [ level: 'advanced platform: 'all type: 'tool domain: [file-handling markup text-processing] tested-under: none support: none license: none see-also: none ] ] ;-- Scan document into the internal format ----------------------------------- scan-ctx: context [ out: [] emit: func ['word d1] [ if string? d1 [trim/tail d1] repend out [word d1] ] emit-section: func [num] [emit (to-word join "sect" num) text title: true] as-file: func [str] [to-file trim str] insert-file: func [str file /local text] [ if file/1 = "%" [remove file] if not exists? file [alert reform ["Missing include file:" file] exit] text: read file insert/part str text any [find text "^/###" tail text] ] space: charset " ^-" chars: complement nochar: charset " ^-^/" text: none para: none title: none ;--- Text Format Language: rules: [some parts] parts: [ ;here: (print here) newline | ;--Document sections: "***" text-line (if title [alert reform ["Duplicate title:" text]] emit title text) | ["===" | "-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) | ;--Special common notations: ":" define opt newline (emit define reduce [text para]) | "*" paragraph opt newline (emit bullet para) | "#" paragraph opt newline (emit enum para) | ";" paragraph | ; comment ;--Commands: "=image" image | "=url" some-chars copy para to newline newline (emit url reduce [text para]) | "=view" left?
