SiSU source documents are plaintext (UTF-8)  2  files

All paragraphs are separated by an empty line.

Markup is comprised of:

  • 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)
  • 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:
  • heading levels defines document structure
  • text basic attributes, italics, bold etc.
  • grouped text (objects), which are to be treated differently, such as code blocks or poems.
  • footnotes/endnotes
  • linked text and images
  • paragraph actions, such as indent, bulleted, numbered-lists, etc.
  • Some interactive help on markup is available, by typing sisu and selecting markup or sisu --help markup

    To check the markup in a file:

    sisu --identify [filename].sst

    For brief descriptive summary of markup history

    sisu --query-history

    or if for a particular version:

    sisu --query-0.38

    Online markup examples are available together with the respective outputs produced from ‹http://www.jus.uio.no/sisu/SiSU/examples.html› or from ‹http://www.jus.uio.no/sisu/sisu_examples/

    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/

    an alternative presentation of markup syntax: /usr/share/doc/sisu/on_markup.txt.gz

    With SiSU installed sample skins may be found in: /usr/share/doc/sisu/markup-samples (or equivalent directory) and if sisu-markup-samples is installed also under: /usr/share/doc/sisu/markup-samples-non-free



    Headers contain either: semantic meta-data about a document, which can be used by any output module of the program, or; processing instructions.

    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:

      % this would be a comment

    This current document is loaded by a master document that has a header similar to this one:

    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 the form @headername: or on the next line and indented by once space :subheadername: All Dublin Core meta tags are available

    @indentifier: information or instructions

    where the "identifier" is a tag recognised by the program, and the "information" or "instructions" belong to the tag/indentifier specified

    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.

    This is a sample header

    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)

    :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

    :B~ [heading text] Second level heading [this is a heading level divider]

    :C~ [heading text] Third level heading [this is a heading level divider]

    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

    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.

    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

      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)

    markup example:

      normal text,  *{emphasis}*, !{bold text}!, /{italics}/, _{underscore}_, "{citation}",
      ^{superscript}^, ,{subscript},, +{inserted text}+, -{strikethrough}-, #{monospace}#

      normal text

      *{emphasis}* [note: can be configured to be represented by bold, italics or underscore]

      !{bold text}!

      /{italics}/

      _{underscore}_

      "{citation}"

      ^{superscript}^

      ,{subscript},

      +{inserted text}+

      -{strikethrough}-

      #{monospace}#

    resulting output:

    normal text, emphasis, bold text, italics, underscore, citation, superscript, subscript, inserted text, strikethrough, monospace

    normal text

    emphasis [note: can be configured to be represented by bold, italics or underscore]

    bold text

    italics

    underscore

    citation

    superscript

    subscript

    inserted text

    strikethrough

    monospace

    markup example:

      ordinary paragraph

      _1 indent paragraph one step

      _2 indent paragraph two steps

      _9 indent paragraph nine steps

    resulting output:

    ordinary paragraph

    indent paragraph one step

    indent paragraph two steps

    indent paragraph nine steps

    markup example:

      _* bullet text

      _1* bullet text, first indent

      _2* bullet text, two step indent

    resulting output:

  • bullet text
  • bullet text, first indent
  • bullet text, two step indent
  • Numbered List (not to be confused with headings/titles, (document structure))

    markup example:

      # numbered list                numbered list 1., 2., 3, etc.

      _# numbered list numbered list indented a., b., c., d., etc.

    Footnotes and endnotes are marked up at the location where they would be indicated within a text. They are automatically numbered. The output type determines whether footnotes or endnotes will be produced

    markup example:

      ~{ a footnote or endnote }~

    resulting output:

    markup example:

      normal text~{ self contained endnote marker & endnote in one }~ continues

    resulting output:

    normal text  4  continues

    markup example:

      normal text ~{* unnumbered asterisk footnote/endnote, insert multiple asterisks if required }~ continues

      normal text ~{** another unnumbered asterisk footnote/endnote }~ continues

    resulting output:

    normal text   *  continues

    normal text   **  continues

    markup example:

      normal text ~[* editors notes, numbered asterisk footnote/endnote series ]~ continues

      normal text ~[+ editors notes, numbered asterisk footnote/endnote series ]~ continues

    resulting output:

    normal text   *1  continues

    normal text   +1  continues

    Alternative endnote pair notation for footnotes/endnotes:

      % 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

    urls found within text are 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).

    markup example:

      normal text http://www.sisudoc.org/ continues

    resulting output:

    normal text ‹http://www.sisudoc.org/› continues

    An escaped url without decoration

    markup example:

      normal text _http://www.sisudoc.org/ continues

      deb http://www.jus.uio.no/sisu/archive unstable main non-free

    resulting output:

    normal text http://www.sisudoc.org/ continues

    deb http://www.jus.uio.no/sisu/archive unstable main non-free

    where a code block is used there is neither decoration nor hyperlinking, code blocks are discussed later in this document

    resulting output:

      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

    markup example:

      about { SiSU }http://url.org markup

    resulting output:

    about SiSU markup

    A shortcut notation is available so the url link may also be provided automatically as a footnote

    markup example:

      about {~^ SiSU }http://url.org markup

    resulting output:

    about SiSU   5  markup

    Internal document links to a tagged location, including an ocn

    markup example:

      about { text links }#link_text

    resulting output:

    about text links

    Shared document collection link

    markup example:

      about { SiSU book markup examples }:SiSU/examples.html

    resulting output:

    markup example:

      { tux.png 64x80 }image

      % various url linked images

      {tux.png 64x80 "a better way" }http://www.sisudoc.org/

      {GnuDebianLinuxRubyBetterWay.png 100x101 "Way Better - with Gnu/Linux, Debian and Ruby" }http://www.sisudoc.org/

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

    resulting output:


    Gnu/Linux - a better way


    Way Better - with Gnu/Linux, Debian and Ruby


    Ruby

    linked url footnote shortcut

      {~^ [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

    167

    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.

    Tables may be prepared in two either of two forms

    markup example:

      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:

    This is a tablethis would become column two of row onecolumn three of row one is here
    And here begins another rowcolumn two of row twocolumn 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

    markup example:  7

    Code tags code{ ... }code (used as with other group tags described above) 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.

    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]

    use of code tags instead of poem compared, resulting output:

    To make an index append to paragraph the book index term relates to it, using an equal sign and curly braces.

    Currently two levels are provided, a main term and if needed a sub-term. Sub-terms are separated from the main term by a colon.

        Paragraph containing main term and sub-term.
        ={Main term:sub-term}

    The index syntax starts on a new line, but there should not be an empty line between paragraph and index markup.

    The structure of the resulting index would be:

        Main term, 1
          sub-term, 1

    Several terms may relate to a paragraph, they are separated by a semicolon. If the term refers to more than one paragraph, indicate the number of paragraphs.

        Paragraph containing main term, second term and sub-term.
        ={first term; second term: sub-term}

    The structure of the resulting index would be:

        First term, 1,
        Second term, 1,
          sub-term, 1

    If multiple sub-terms appear under one paragraph, they are separated under the main term heading from each other by a pipe symbol.

        Paragraph containing main term, second term and sub-term.
        ={Main term:sub-term+1|second sub-term

        A paragraph that continues discussion of the first sub-term

    The plus one in the example provided indicates the first sub-term spans one additional paragraph. The logical structure of the resulting index would be:

        Main term, 1,
          sub-term, 1-3,
          second sub-term, 1,



    It is possible to build a document by creating a master document that requires other documents. 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

    basic markup for importing a document into a master document

      << 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.

      << filename.ssi

      <<{filename.ssi}

      % using textlink alternatives

      << |filename.ssi|@|^|





    2.0 introduced new headers and is therefore incompatible with 1.0 though otherwise the same with the addition of a couple of tags (i.e. a superset)

    0.38 is substantially current for version 1.0

    depreciated 0.16 supported, though file names were changed at 0.37

  • sisu --query=[sisu version [0.38] or 'history]
  • provides a short history of changes to SiSU markup

    SiSU 2.0 (2010-03-06:09/6) same as 1.0, apart from the changing of headers and the addition of a monospace tag related headers now grouped, e.g.

      @title:
       :subtitle:

      @creator:
       :author:
       :translator:
       :illustrator:

      @rights:
       :text:
       :illustrations:

    see document markup samples, and sisu --help headers

    the monospace tag takes the form of a hash '#'

      #{ this enclosed text would be monospaced }#

    1.0 (2009-12-19:50/6) same as 0.69

    0.69 (2008-09-16:37/2) (same as 1.0) and as previous (0.57) with the addition of book index tags

      /^={.+?}$/

    e.g. appended to a paragraph, on a new-line (without a blank line in between) logical structure produced assuming this is the first text "object"

       ={GNU/Linux community distribution:Debian+2|Fedora|Gentoo;Free Software Foundation+5}

      Free Software Foundation, 1-6
      GNU/Linux community distribution, 1
          Debian, 1-3
          Fedora, 1
          Gentoo,

    0.66 (2008-02-24:07/7) same as previous, adds semantic tags, [experimental and not-used]

      /[:;]{.+?}[:;][a-z+]/

    0.57 (2007w34/4) SiSU 0.57 is the same as 0.42 with the introduction of some a shortcut to use the headers @title and @creator in the first heading [expanded using the contents of the headers @title: and @author:]

      :A~ @title by @author

    0.52 (2007w14/6) declared document type identifier at start of text/document:

    SiSU 0.52

    or, backward compatible using the comment marker:

    % SiSU 0.38

    variations include 'SiSU (text|master|insert) [version]' and 'sisu-[version]'

    0.51 (2007w13/6) skins changed (simplified), markup unchanged

    0.42 (2006w27/4) * (asterisk) type endnotes, used e.g. in relation to author

    SiSU 0.42 is the same as 0.38 with the introduction of some additional endnote types,

    Introduces some variations on endnotes, in particular the use of the asterisk

      ~{* for example for describing an author }~ and ~{** for describing a second author }~

    * for example for describing an author

    ** for describing a second author

    and

      ~[* my note ]~ or ~[+ another note ]~

    which numerically increments an asterisk and plus respectively

    *1 my note +1 another note

    0.38 (2006w15/7) introduced new/alternative notation for headers, e.g. @title: (instead of 0~title), and accompanying document structure markup, :A,:B,:C,1,2,3 (maps to previous 1,2,3,4,5,6)

    SiSU 0.38 introduced alternative experimental header and heading/structure markers,

      @headername: and headers :A~ :B~ :C~ 1~ 2~ 3~

    as the equivalent of:

      0~headername and headers 1~ 2~ 3~ 4~ 5~ 6~

    The internal document markup of SiSU 0.16 remains valid and standard Though note that SiSU 0.37 introduced a new file naming convention

    SiSU has in effect two sets of levels to be considered, using 0.38 notation A-C headings/levels, pre-ordinary paragraphs /pre-substantive text, and 1-3 headings/levels, levels which are followed by ordinary text. This may be conceptualised as levels A,B,C, 1,2,3, and using such letter number notation, in effect: A must exist, optional B and C may follow in sequence (not strict) 1 must exist, optional 2 and 3 may follow in sequence i.e. there are two independent heading level sequences A,B,C and 1,2,3 (using the 0.16 standard notation 1,2,3 and 4,5,6) on the positive side: the 0.38 A,B,C,1,2,3 alternative makes explicit an aspect of structuring documents in SiSU that is not otherwise obvious to the newcomer (though it appears more complicated, is more in your face and likely to be understood fairly quickly); the substantive text follows levels 1,2,3 and it is 'nice' to do most work in those levels

    0.37 (2006w09/7) introduced new file naming convention, .sst (text), .ssm (master), .ssi (insert), markup syntax unchanged

    SiSU 0.37 introduced new file naming convention, using the file extensions .sst .ssm and .ssi to replace .s1 .s2 .s3 .r1 .r2 .r3 and .si

    this is captured by the following file 'rename' instruction:

      rename 's/\.s[123]$/\.sst/' *.s{1,2,3}
      rename 's/\.r[123]$/\.ssm/' *.r{1,2,3}
      rename 's/\.si$/\.ssi/' *.si

    The internal document markup remains unchanged, from SiSU 0.16

    0.35 (2005w52/3) sisupod, zipped content file introduced

    0.23 (2005w36/2) utf-8 for markup file

    0.22 (2005w35/3) image dimensions may be omitted if rmagick is available to be relied upon

    0.20.4 (2005w33/4) header 0~links

    0.16 (2005w25/2) substantial changes introduced to make markup cleaner, header 0~title type, and headings [1-6]~ introduced, also percentage sign (%) at start of a text line as comment marker

    SiSU 0.16 (0.15 development branch) introduced the use of

    the header 0~ and headings/structure 1~ 2~ 3~ 4~ 5~ 6~

    in place of the 0.1 header, heading/structure notation

    SiSU 0.1 headers and headings structure represented by header 0{~ and headings/structure 1{ 2{ 3{ 4{~ 5{ 6{



     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.

     2. files should be prepared using UTF-8 character encoding

     3. a footnote or endnote

     4. self contained endnote marker & endnote in one

     * unnumbered asterisk footnote/endnote, insert multiple asterisks if required

     ** another unnumbered asterisk footnote/endnote

     *1. editors notes, numbered asterisk footnote/endnote series

     +1. editors notes, numbered asterisk footnote/endnote series
