:A~? @title @creator

:B~? SiSU Markup

1~markup Introduction to SiSU Markup~{ 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~ Summary

SiSU source documents are plaintext (UTF-8)~{ files should be prepared using UTF-8 character encoding }~ 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:

_1* heading levels defines document structure

_1* text basic attributes, italics, bold etc.

_1* grouped text (objects), which are to be treated differently, such as code blocks or poems.

_1* footnotes/endnotes

_1* linked text and images

_1* 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:

_1 sisu --identify [filename].sst

For brief descriptive summary of markup history

_1 sisu --query-history

or if for a particular version:

_1 sisu --query-0.38

2~ Markup Rules, document structure and metadata requirements

minimal content/structure requirement:

[metadata]

@title:

@creator:

[levels]

``` code
A~ (level A [title])
1~ (at least one level 1 [segment/(chapter)])
```

structure rules (document heirarchy, heading levels):

there are two sets of heading levels ABCD (title & parts if any) and 123 (segment & subsegments if any)

sisu has the fllowing levels:

``` code
A~ [title]              .
   required (== 1)   followed by B~ or 1~
B~ [part]               *
   followed by C~ or 1~
C~ [subpart]            *
   followed by D~ or 1~
D~ [subsubpart]         *
   followed by 1~
1~ [segment (chapter)]  +
   required (>= 1)   followed by text or 2~
text                    *
   followed by more text or 1~, 2~
   or relevant part *()
2~ [subsegment]         *
   followed by text or 3~
text                    *
   followed by more text or 1~, 2~ or 3~
   or relevant part, see *()
3~ [subsubsegment]      *
   followed by text
text                    *
   followed by more text or 1~, 2~ or 3~ or relevant part, see *()

*(B~ if none other used;
  if C~ is last used: C~ or B~;
  if D~ is used: D~, C~ or B~)
```

``` code
* level A~ is the tile and is mandatory
* there can only be one level A~
* heading levels BCD, are optional and there may be several of each
  (where all three are used corresponding to e.g. Book Part Section)
  * sublevels that are used must follow each other sequentially
    (alphabetically),
* heading levels A~ B~ C~ D~ are followed by other heading levels rather
  than substantive text
  which may be the subsequent sequential (alphabetic) heading part level
  or a heading (segment) level 1~
* there must be at least one heading (segment) level 1~
  (the level on which the text is segmented, in a book would correspond
  to the Chapter level)
* additional heading levels 1~ 2~ 3~ are optional and there may be several
  of each
* heading levels 1~ 2~ 3~ are followed by text (which may be followed by
  the same heading level)
  and/or the next lower numeric heading level (followed by text)
  or indeed return to the relevant part level
  (as a corollary to the rules above substantive text/ content
  must be preceded by a level 1~ (2~ or 3~) heading)
```

2~ Markup Examples

3~ Online

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

3~ Installed

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

1~headers Markup of Headers

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:

code{

% this would be a comment

}code

2~ Sample Header

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

2~ Available Headers

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

!_ @identifier:
information or instructions

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

1~ Markup of Substantive Text

2~heading_levels Heading Levels

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

code{

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)

}code

2~ Font Attributes

!_ markup example:

code{

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}#

}code

!_ 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}#

2~ Indentation and bullets

!_ markup example:

code{

ordinary paragraph

_1 indent paragraph one step

_2 indent paragraph two steps

_9 indent paragraph nine steps

}code

!_ resulting output:

ordinary paragraph

_1 indent paragraph one step

_2 indent paragraph two steps

_9 indent paragraph nine steps

!_ markup example:

code{

_* bullet text

_1* bullet text, first indent

_2* bullet text, two step indent

}code

!_ resulting output:

_* bullet text

_1* bullet text, first indent

_2* bullet text, two step indent

Numbered List (not to be confused with headings/titles, (document structure))

!_ markup example:

code{

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

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

}code

2~ Hanging Indents

!_ markup example:

code{

_0_1 first line no indent,
rest of paragraph indented one step

_1_0 first line indented,
rest of paragraph no indent

in each case level may be 0-9

}code

!_ resulting output:

_0_1 first line no indent, rest of paragraph indented one step; first line no indent, rest of paragraph indented one step; first line no indent, rest of paragraph indented one step; first line no indent, rest of paragraph indented one step; first line no indent, rest of paragraph indented one step; first line no indent, rest of paragraph indented one step; first line no indent, rest of paragraph indented one step; first line no indent, rest of paragraph indented one step; first line no indent, rest of paragraph indented one step;

A regular paragraph.

_1_0 first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent first line indented, rest of paragraph no indent

in each case level may be 0-9

_0_1 *{live-build}* A collection of scripts used to build customized Debian Livesystems. /{live-build}/ was formerly known as live-helper, and even earlier known as live-package.

_0_1 *{live-build}* \\
A collection of scripts used to build customized Debian Livesystems. /{live-build}/ was formerly known as live-helper, and even earlier known as live-package.

2~ Footnotes / Endnotes

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:

code{

~{ a footnote or endnote }~

}code

!_ resulting output:

~{ a footnote or endnote }~

!_ markup example:

code{

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

}code

!_ resulting output:

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

!_ markup example:

code{

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

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

}code

!_ resulting output:

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

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

!_ markup example:

code{

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

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

}code

!_ resulting output:

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

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

!_ Alternative endnote pair notation for footnotes/endnotes:

code{

% note the endnote marker "~^"

normal text~^ continues

^~ endnote text following the paragraph in which the marker occurs

}code

the standard and pair notation cannot be mixed in the same document

2~ Links

3~ Naked URLs within text, dealing with urls

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:

code{

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

}code

!_ resulting output:

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

An escaped url without decoration

!_ markup example:

code{

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

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

}code

!_ 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:

code{

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

}code

3~link_text Linking Text

To link text or an image to a url the markup is as follows

!_ markup example:

code{

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

}code

!_ resulting output:

about { SiSU }http://www.sisudoc.org/ markup

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

!_ markup example:

code{

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

}code

!_ resulting output:

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

Internal document links to a tagged location, including an ocn

!_ markup example:

code{

about { text links }#link_text

}code

!_ resulting output:

about { text links }#link_text

Shared document collection link

!_ markup example:

code{

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

}code

!_ resulting output:

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

3~ Linking Images

!_ markup example:

code{

{ 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/

}code

!_ resulting output:

{ tux.png 64x80 }image

{tux.png 64x80 "Gnu/Linux - 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/

!_ linked url footnote shortcut

code{

{~^ [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

}code

code{

text marker *~name

}code

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.

3~ Link shortcut for multiple versions of a sisu document in the same directory tree

!_ markup example:

code{

!_ /{"Viral Spiral"}/, David Bollier

{ "Viral Spiral", David Bollier [3sS]}viral_spiral.david_bollier.sst

}code


!_ /{"Viral Spiral"}/, David Bollier

{ "Viral Spiral", David Bollier [3sS]}viral_spiral.david_bollier.sst

2~ Grouped Text

3~ Tables

Tables may be prepared in two either of two forms

!_ markup example:

code{

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

}code

!_ resulting output:

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

a second form may be easier to work with in cases where there is not much information in each column

*{markup example:}*~{ Table from the Wealth of Networks by Yochai Benkler \\ http://www.jus.uio.no/sisu/the_wealth_of_networks.yochai_benkler }~

code{

3~ Code

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:

                   dear Sir,

}code

2~ Additional breaks - linebreaks within objects, column and page-breaks

3~ line-breaks

To break a line within a "paragraph object", two backslashes \\\\ \\ with a space before and a space or newline after them \\ may be used.

code{

To break a line within a "paragraph object",
two backslashes \\ with a space before
and a space or newline after them \\
may be used.

}code

The html break br enclosed in angle brackets (though undocumented) is available in versions prior to 3.0.13 and 2.9.7 (it remains available for the time being, but is depreciated).

To draw a dividing line dividing paragraphs, see the section on page breaks.

3~ page breaks

Page breaks are only relevant and honored in some output formats. A page break or a new page may be inserted manually using the following markup on a line on its own:

page new =\\= (or <:pn>) breaks the page, starts a new page.

page break -\\- (or <:pb>) breaks a column, starts a new column, if using columns, else breaks the page, starts a new page.

page break line across page -..- draws a dividing line, dividing paragraphs

page break:

code{

-\\-

}code

page (break) new:

code{

=\\=

}code

page (break) line across page (dividing paragraphs):

code{

-..-

}code

2~ Book index

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.

code{

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

}code

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:

code{

  Main term, 1
    sub-term, 1

}code

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.

code{

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

}code

The structure of the resulting index would be:

code{

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

}code

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

code{

  Paragraph containing main term, second term and sub-term.
  ={Main term:
      sub-term+2|second sub-term;
    Another term
   }

  A paragraph that continues discussion of the first sub-term

}code

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:

code{

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

}code

1~ Composite documents markup

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). 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

code{

<< filename1.sst

<< filename2.ssi

}code

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.

1~ Substitutions

!_ markup example:

code{

The current Debian is ${debian_stable} the next debian will be ${debian_testing}

Configure substitution in _sisu/sisu_document_make

@make:
 :substitute: /${debian_stable}/,'*{Wheezy}*' /${debian_testing}/,'*{Jessie}*'

}code

!_ resulting output:

The current Debian is ${debian_stable} the next debian will be ${debian_testing}
