SiSU - Markup [0.58],
Ralph Amissah 1 SiSU Markup 2 1. Introduction to SiSU Markup1 1. From sometime after SiSU 0.58 it should be possible to describe SiSU markup using SiSU, which though not an original design goal is useful. 3 1.1 Summary 4 SiSU source documents are plaintext (UTF-8)2 files 2. files should be prepared using UTF-8 character encoding 5 All paragraphs are separated by an empty line. 6 Markup is comprised of: 7 at the top of a document, the document header made up of semantic meta-data about the document and if desired additional processing instructions (such an instruction to automatically number headings from a particular level down) 8 followed by the prepared substantive text of which the most important single characteristic is the markup of different heading levels, which define the primary outline of the document structure. Markup of substantive text includes: 9 heading levels defines document structure 10 text basic attributes, italics, bold etc. 11 grouped text (objects), which are to be treated differently, such as code blocks or poems. 12 footnotes/endnotes 13 linked text and images 14 paragraph actions, such as indent, bulleted, numbered-lists, etc. 15 Some interactive help on markup is available, by typing sisu and selecting markup or sisu --help markup 16 1.2 Markup Examples 17 1.2.1 Online 18 Online markup examples are available together with the respective outputs produced from <http://www.jus.uio.no/sisu/SiSU/2.html> or from <http://www.jus.uio.no/sisu/sisu_examples/> 19 There is of course this document, which provides a cursory overview of sisu markup and the respective output produced: <http://www.jus.uio.no/sisu/sisu_markup/> 20 Some example marked up files are available as html with syntax highlighting for viewing: <http://www.jus.uio.no/sisu/sample/syntax> 21 an alternative presentation of markup syntax: <http://www.jus.uio.no/sisu/sample/on_markup.txt> 22 1.2.2 Installed 23 With SiSU installed sample skins may be found in: /usr/share/doc/sisu/sisu_markup_samples/dfsg (or equivalent directory) and if sisu-markup-samples is installed also under: /usr/share/doc/sisu/sisu_markup_samples/non-free 24 2. Markup of Headers 25 Headers consist of semantic meta-data about a document, which can be used by any output module of the program; and may in addition include extra processing instructions. 26 Note: the first line of a document may include information on the markup version used in the form of a comment. Comments are a percentage mark at the start of a paragraph (and as the first character in a line of text) followed by a space and the comment: 27 28      % this would be a comment     2.1 Sample Header 29 This current document has a header similar to this one (without the comments): 30 31      % SiSU 0.57

     @level: new=C; break=1; num_top=1

     % comment: in this @level header num_top=1 starts automatic heading numbering at heading level 1 (numbering continues 3 levels down); the new and break instructions are used by the LaTeX/pdf and odf output to determine where to put page breaks (that are not used by html output or say sql database population).

     @skin: skin_sisu_manual

     % skins modify the appearance of a document and are placed in a sub-directory under ./_sisu/skin ~/.sisu/skin or /etc/sisu/skin. A skin may affect single documents that request them, all documents in a directory, or be site-wide. (A document is affected by a single skin)

     2.2 Available Headers 32 Header tags appear at the beginning of a document and provide meta information on the document (such as the Dublin Core), or information as to how the document as a whole is to be processed. All header instructions take either the form @headername: or 0~headername. All Dublin Core meta tags are available 33 @indentifier: information or instructions 34 where the "identifier" is a tag recognised by the program, and the "information" or "instructions" belong to the tag/indentifier specified 35 Note: a header where used should only be used once; all headers apart from @title: are optional; the @structure: header is used to describe document structure, and can be useful to know. 36 This is a sample header 37 % SiSU 0.38 [declared file-type identifier with markup version] 38 @title: [title text] This is the title of the document and used as such, this header is the only one that is mandatory 39 @subtitle: The Subtitle if any 40 @creator: [or @author:] Name of Author 41 @subject: (whatever your subject) 42 @description: 43 @publisher: 44 @contributor: 45 @translator: [or @translated_by:] 46 @illustrator: [or @illustrated_by:] 47 @prepared_by: [or @digitized_by:] 48 @date: 2000-08-27 [ also @date.created: @date.issued: @date.available: @date.valid: @date.modified: ] 49 @type: article 50 @format: 51 @identifier: 52 @source: 53 @language: [or @language.document:] [country code for language if available, or language, English, en is the default setting] (en - English, fr - French, de - German, it - Italian, es - Spanish, pt - Portuguese, sv - Swedish, da - Danish, fi - Finnish, no - Norwegian, is - Icelandic, nl - Dutch, et - Estonian, hu - Hungarian, pl - Polish, ro - Romanian, ru - Russian, el - Greek, uk - Ukranian, tr - Turkish, sk - Slovak, sl - Slovenian, hr - Croatian, cs - Czech, bg - Bul garian ) [however, encodings are not available for all of the languages listed.] 54 [@language.original: original language in which the work was published] 55 @papersize: (A4|US_letter|book_B5|book_A5|US_legal) 56 @relation: 57 @coverage: 58 @rights: Copyright (c) Name of Right Holder, all rights reserved, or as granted: public domain, copyleft, creative commons variant, etc. 59 @owner: 60 @keywords: text document generation processing management latex pdf structured xml citation [your keywords here, used for example by rss feeds, and in sql searches] 61 @abstract: [paper abstract, placed after table of contents] 62 @comment: [...] 63 @catalogue: loc=[Library of Congress classification]; dewey=[Dewey classification]; isbn=[ISBN]; pg=[Project Gutenberg text number] 64 @classify_loc: [Library of Congress classification] 65 @classify_dewey: [Dewey classification] 66 @classify_isbn: [ISBN] 67 @classify_pg: [Project Gutenberg text number] 68 @prefix: [prefix is placed just after table of contents] 69 @prefix_a: [prefix is placed just before table of contents - not implemented] 70 @prefix_b: 71 @rcs: $Id: sisu_markup.sst,v 1.2 2007/09/08 17:12:47 ralph Exp $ [used by rcs or cvs to embed version (revision control) information into document, rcs or cvs can usefully provide a history of updates to a document ] 72 @structure: PART; CHAPTER; SECTION; ARTICLE; none; none;
optional, document structure can be defined by words to match or regular expression (the regular expression is assumed to start at the beginning of a line of text i.e. ^) default markers :A~ to :C~ and 1~ to 6~ can be used within text instead, without this header tag, and may be used to supplement the instructions provided in this header tag if provided (@structure: is a synonym for @toc:) 73 @level: newpage=3; breakpage=4
[paragraph level, used by latex to breakpages, the page is optional eg. in newpage] 74 @markup: information on the markup used, e.g. new=1,2,3; break=4; num_top=4 [or newpage=1,2,3; breakpage=4; num_top=4] newpage and breakpage, heading level, used by LaTeX to breakpages. breakpage: starts on a new page in single column text and on a new column in double column text; newpage: starts on a new page for both single and double column texts.
num_top=4 [auto-number document, starting at level 4. the default is to provide 3 levels, as in 1 level 4, 1.1 level 5, 1.1.1 level 6, markup to be merged within level]
num_extract [take numbering of headings provided (manually in marked up source document), and use for numbering of segments. Available where a clear numbering structure is provided within document, without the repetition of a number in a header.] [In 0.38 notation, you would map to the equivalent levels, the examples provided would map to the following new=A,B,C; break=1; num_top=1 [or newpage=A,B,C; breakpage=1; num_top=1] see headings] 75 @bold: [regular expression of words/phrases to be made bold] 76 @italics: [regular expression of words/phrases to italicise] 77 @vocabulary: name of taxonomy/vocabulary/wordlist to use against document 78 @skin: skin_doc_[name_of_desired_document_skin]
skins change default settings related to the appearance of documents generated, such as the urls of the home site, and the icon/logo for the document or site. 79 @links: { SiSU }http://www.jus.uio.no/sisu/;

Markup of Substantive Text 82 3.1 Heading Levels 83 Heading levels are :A~ ,:B~ ,:C~ ,1~ ,2~ ,3~ ... :A - :C being part / section headings, followed by other heading levels, and 1 -6 being headings followed by substantive text or sub-headings. :A~ usually the title :A~? conditional level 1 heading (used where a stand-alone document may be imported into another) 84 :A~ [heading text] Top level heading [this usually has similar content to the title @title: ] NOTE: the heading levels described here are in 0.38 notation, see heading 85 :B~ [heading text] Second level heading [this is a heading level divider] 86 :C~ [heading text] Third level heading [this is a heading level divider] 87 1~ [heading text] Top level heading preceding substantive text of document or sub-heading 2, the heading level that would normally be marked 1. or 2. or 3. etc. in a document, and the level on which sisu by default would break html output into named segments, names are provided automatically if none are given (a number), otherwise takes the form 1~my_filename_for_this_segment 88 2~ [heading text] Second level heading preceding substantive text of document or sub-heading 3, the heading level that would normally be marked 1.1 or 1.2 or 1.3 or 2.1 etc. in a document. 89 3~ [heading text] Third level heading preceding substantive text of document, that would normally be marked 1.1.1 or 1.1.2 or 1.2.1 or 2.1.1 etc. in a document 90 91      1~filename level 1 heading,

     % the primary division such as Chapter that is followed by substantive text, and may be further subdivided (this is the level on which by default html segments are made)     3.2 Font Attributes 92 markup example: 93 94      normal text !{emphasis}! *{bold text}* _{underscore}_ /{italics}/ "{citation}" ^{superscript}^ ,{subscript}, +{inserted text}+

     normal text

     !{emphasis}!

     *{bold text}*

     _{underscore}

     /{italics}/

     "{citation}"

     ^{superscript}^

     ,{subscript},

     +{inserted text}+

     -{strikethrough}-     resulting output: 95 normal text emphasis bold text underscore italics citation superscript subscript inserted text strikethrough 96 normal text 97 emphasis 98 bold text 99 underscore 100 italics 101 citation 102 superscript 103 subscript 104 inserted text 105 strikethrough 106 3.3 Indentation and bullets 107 markup example: 108 109      ordinary paragraph

     _1 indent paragraph one step

     _2 indent paragraph two steps

     _9 indent paragraph nine steps     resulting output: 110 ordinary paragraph 111 indent paragraph one step 112 indent paragraph two steps 113 indent paragraph nine steps 114 markup example: 115 116      _* bullet text

     _1* bullet text, first indent

     _2* bullet text, two step indent     resulting output: 117 bullet text 118 bullet text, first indent 119 bullet text, two step indent 120 Numbered List (not to be confused with headings/titles, (document structure)) 121 markup example: 122 123      # numbered list                numbered list 1., 2., 3, etc.

     _# numbered list numbered list indented a., b., c., d., etc.     3.4 Footnotes / Endnotes 124 Footnotes and endnotes not distinguished in markup. They are automatically numbered. Depending on the output file format (html, odf, pdf etc.), the document output selected will have either footnotes or endnotes. 125 markup example: 126 127      ~{ a footnote or endnote }~     resulting output: 128 3 3. a footnote or endnote 129 markup example: 130 131      normal text~{ self contained endnote marker & endnote in one }~ continues     resulting output: 132 normal text4 continues 4. self contained endnote marker & endnote in one 133 markup example: 134 135      normal text ~{* unnumbered asterisk footnote/endnote, insert multiple asterisks if required }~ continues

     normal text ~{** another unnumbered asterisk footnote/endnote }~ continues     resulting output: 136 normal text * continues * unnumbered asterisk footnote/endnote, insert multiple asterisks if required 137 normal text ** continues ** another unnumbered asterisk footnote/endnote 138 markup example: 139 140      normal text ~[* editors notes, numbered asterisk footnote/endnote series ]~ continues

     normal text ~[+ editors notes, numbered asterisk footnote/endnote series ]~ continues     resulting output: 141 normal text *1 continues *1 editors notes, numbered asterisk footnote/endnote series 142 normal text +1 continues +1 editors notes, numbered asterisk footnote/endnote series 143 Alternative endnote pair notation for footnotes/endnotes: 144 145      % note the endnote marker "~^"

     normal text~^ continues

     ^~ endnote text following the paragraph in which the marker occurs     the standard and pair notation cannot be mixed in the same document 146 3.5 Links 147 3.5.1 Naked URLs within text, dealing with urls 148 urls are found within text and marked up automatically. A url within text is automatically hyperlinked to itself and by default decorated with angled braces, unless they are contained within a code block (in which case they are passed as normal text), or escaped by a preceding underscore (in which case the decoration is omitted). 149 markup example: 150 151      normal text http://www.jus.uio.no/sisu continues     resulting output: 152 normal text <http://www.jus.uio.no/sisu> continues 153 An escaped url without decoration 154 markup example: 155 156      normal text _http://www.jus.uio.no/sisu continues

     deb _http://www.jus.uio.no/sisu/archive unstable main non-free     resulting output: 157 normal text http://www.jus.uio.no/sisu continues 158 deb http://www.jus.uio.no/sisu/archive unstable main non-free 159 where a code block is used there is neither decoration nor hyperlinking, code blocks are discussed later in this document 160 resulting output: 161 162      deb http://www.jus.uio.no/sisu/archive unstable main non-free
     deb-src http://www.jus.uio.no/sisu/archive unstable main non-free     To link text or an image to a url the markup is as follows 163 markup example: 164 165      about { SiSU }http://url.org markup     3.5.2 Linking Text 166 resulting output: 167 about SiSU markup 168 A shortcut notation is available so the url link may also be provided automatically as a footnote 169 markup example: 170 171      about {~^ SiSU }http://url.org markup     resulting output: 172 about SiSU 5 markup 5. <http://www.jus.uio.no/sisu/> 173 3.5.3 Linking Images 174 markup example: 175 176      {tux.png 64x80 }image

     % various url linked images

     {tux.png 64x80 "a better way" }http://www.jus.uio.no/sisu/

     {~^ ruby_logo.png "Ruby" }http://www.ruby-lang.org/en/

     resulting output: 177 {tux.png 64x80 }image 178 [tux.png] "Gnu/Linux - a better way" 179 [ ruby_logo (png missing) ] 6 6. <http://www.ruby-lang.org/en/> 180 [GnuDebianLinuxRubyBetterWay.png] "Way Better - with Gnu/Linux, Debian and Ruby" 181 linked url footnote shortcut 182 183      {~^ [text to link] }http://url.org

     % maps to: { [text to link] }http://url.org ~{ http://url.org }~

     % which produces hyper-linked text within a document/paragraph, with an endnote providing the url for the text location used in the hyperlink     184      text marker *~name     note at a heading level the same is automatically achieved by providing names to headings 1, 2 and 3 i.e. 2~[name] and 3~[name] or in the case of auto-heading numbering, without further intervention. 185 3.6 Grouped Text 186 3.6.1 Tables 187 Tables may be prepared in two either of two forms 188 markup example: 189 190      table{ c3; 40; 30; 30;

     This is a table
     this would become column two of row one
     column three of row one is here

     And here begins another row
     column two of row two
     column three of row two, and so on

     }table     resulting output: 191
This is a table this would become column two of row one column three of row one is here
And here begins another row column two of row two column three of row two, and so on
a second form may be easier to work with in cases where there is not much information in each column 193 markup example:7 7. Table from the Wealth of Networks by Yochai Benkler

a trial,
dear Sir,
With

 3.6.4 Code 214 Code tags are used to escape regular sisu markup, and have been used extensively within this document to provide examples of SiSU markup. You cannot however use code tags to escape code tags. They are however used in the same way as group or poem tags. 215 A code-block is treated as an object and given a single object number. [an option to number each line of code may be considered at some later time] 216 use of code tags instead of poem compared, resulting output: 217 218                          'Fury said to a

The documents required may be complete documents that could be generated independently, or they could be markup snippets, prepared so as to be easily available to be placed within another text. If the calling document is a master document (built from other documents), it should be named with the suffix .ssm Within this document you would provide information on the other documents that should be included within the text. These may be other documents that would be processed in a regular way, or markup bits prepared only for inclusion within a master document .sst regular markup file, or .ssi (insert/information) A secondary file of the composite document is built prior to processing with the same prefix and the suffix ._sst 220 basic markup for importing a document into a master document 221 222      << |filename1.sst|@|^|

     << |filename2.ssi|@|^|     The form described above should be relied on. Within the Vim editor it results in the text thus linked becoming hyperlinked to the document it is calling in which is convenient for editing. Alternative markup for importation of documents under consideration, and occasionally supported have been. 223 224      r{filename}
