SISU - README
=============

INTRODUCTION
************

INTRODUCTION - WHAT IS SISU?
----------------------------

*SiSU* is a lightweight markup based document creation and publishing framework
that is controlled from the command line. Prepare documents for *SiSU* using
your text editor of choice, then use *SiSU* to generate various output document
formats.

From a single lightly prepared document (plain-text /UTF-8/) sisu custom builds
several standard output formats which share a common (text object) numbering
system for citation of content within a document (that also has implications
for search). The sisu engine works with an abstraction of the document's
structure and content from which it is possible to generate different forms of
representation of the document. *SiSU* produces: plain-text, /HTML/, /XHTML/,
/XML/, /EPUB/, /ODF/: /ODT/ (Opendocument), /LaTeX/, /PDF/, and populates an
/SQL/ database (/PostgreSQL/ or /SQLite/) with text objects, roughly, paragraph
sized chunks so that document searches are done at this level of granularity.

Outputs share a common citation numbering system, associated with text objects
and any semantic meta-data provided about the document.

*SiSU* also provides concordance files, document content certificates and
manifests of generated output. Book indexes may be made.

Some document markup samples are provided in the package sisu -markup-samples.

INSTALL OR RUN WITHOUT INSTALLATION
***********************************

SOURCE TREE
-----------

RUN OFF SOURCE PACKAGE DIRECTORY TREE (WITHOUT INSTALLING)
..........................................................

Download & unpack the latest source tarball

or

Git clone the latest source, to clone the latest source without the repo
history:

git clone --depth 1 git://git.sisudoc.org/git/code/sisu.git --branch upstream

Provided you have *Ruby*, *SiSU* can be run without installation straight from
the source package directory tree. Run ruby against the full path to bin/sisu
(in the unzipped source package directory tree)

Note however, that additional external package dependencies, such as texlive
(for pdfs), sqlite3 or postgresql (for search) should you desire to use them
are not taken care of for you.

GEM INSTALL
...........

Gem install, you need to:

(i) create the gemspec; (ii) build the gem (from the gemspec); (iii) install
the gem


----------------------------------------

GEM INSTALL WITH QI (QUICK INSTALL) SCRIPT
..........................................

(This requires that ruby -thor is installed).

qi (quick install) can go through the steps required to install the gem:

  qi gem --create --build --install --stable

or

  qi gem --create --build --install --unstable


----------------------------------------

GEM INSTALL WITH RAKE
.....................

Provided you have ruby & rake, this can be done with the single command:

  rake gem_create_build_install # (to build and install, alias gemcbi)

for individual steps (create, build, install) see rake options, rake -T to
specify sisu version for sisu installed via gem

For a list of alternative actions you may type:

  rake help

  rake -T

Rake: <https://rake.rubyforge.org/> <https://rubyforge.org/frs/?group_id=50>


----------------------------------------

MISC GEM
........

gem search sisu

  sisu _7.0.0_ --version

  sisu _7.0.0_ --version

to uninstall sisu installed via gem

  sudo gem uninstall --verbose sisu

DIRECT INSTALLATION WITH QI (QUICK INSTALL) SCRIPT
..................................................

(This requires that ruby -thor is installed).

Root will be requested as required:

  qi setup --bin --lib --conf --data --share --man

or

  qi setup --all

You may wish to do a dryrun to see where files would be installed without
copying them, to do so add the flag --dryrun

INSTALLATION WITH SETUP.RB
..........................

It should also be possible to install sisu using setup.rb

this is a three step process, in the root directory of the unpacked *SiSU* as
root type:

ruby setup.rb config
ruby setup.rb setup
#[as root:]
ruby setup.rb install

further information:
<https://i.loveruby.net/en/projects/setup/>
<https://i.loveruby.net/en/projects/setup/doc/usage.html>

  ruby setup.rb config && ruby setup.rb setup && sudo ruby setup.rb install

UNIX/LINUX DISTRIBUTION
-----------------------

A distribution install should take care of the dependencies of sisu for
producing various outputs.

DEBIAN
......

*SiSU* is available off the *Debian* archives. It should necessary only to run
as root, Using apt-get:

  apt-get update

  apt get install sisu-complete

(all sisu dependencies should be taken care of)

If there are newer versions of *SiSU* upstream, they will be available by
adding the following to your sources list /etc/apt/sources.list

#/etc/apt/sources.list

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

The non-free section is for sisu markup samples provided, which contain
authored works the substantive text of which cannot be changed, and which as a
result do not meet the debian free software guidelines.

*SiSU* is developed on *Debian*, and packages are available for *Debian* that
take care of the dependencies encountered on installation.

The package is divided into the following components:

  *sisu*, the base code, (the main package on which the others depend), without
  any dependencies other than ruby (and for convenience the ruby webrick web
  server), this generates a number of types of output on its own, other
  packages provide additional functionality, and have their dependencies

  *sisu-complete*, a dummy package that installs the whole of greater sisu as
  described below, apart from sisu -examples

  *sisu-pdf*, dependencies used by sisu to produce pdf from /LaTeX/ generated

  *sisu-postgresql*, dependencies used by sisu to populate postgresql database
  (further configuration is necessary)

  *sisu-sqlite*, dependencies used by sisu to populate sqlite database

  *sisu-markup-samples*, sisu markup samples and other miscellany (under
  *Debian* Free Software Guidelines non-free)

*SiSU* is available off Debian Unstable and Testing [link:
<https://packages.debian.org/cgi-bin/search_packages.pl?searchon=names&subword=1&version=all&release=all&keywords=sisu>]
[^1] install it using apt-get, aptitude or alternative *Debian* install tools.

COMMANDS SUMMARY
----------------

DESCRIPTION
...........

*SiSU* is a document publishing system, that from a simple single marked-up
document, produces multiple output formats including: /plaintext/, /HTML/,
/XHTML/, /XML/, /EPUB/, /ODT/ (/OpenDocument/ (/ODF/) text), /LaTeX/, /PDF/,
info, and /SQL/ (/PostgreSQL/ and /SQLite/) , which share text object numbers
("object citation numbering") and the same document structure information. For
more see: <https://sisudoc.org> or <https://git.sisudoc.org>

see --rsync

*-r [filename/wildcard]*
see --scp

*--redirect[=directory_path] [filename/wildcard]*
places output in subdirectory under specified directory, subdirectory uses the
filename (without the suffix). If no output directory is specified places the
subdirectory under the current directory (pwd). Unlike using default settings
/HTML/ files have embedded css. Compare --dump

*--rst [filename/wildcard/url]*
ReST (rST restructured text) smart text (not available)

*--rsync [filename/wildcard]*
copies sisu output files to remote host using rsync. This requires that
sisurc.yml has been provided with information on hostname and username, and
that you have your "keys" and ssh agent in place. Note the behavior of rsync
different if -R is used with other flags from if used alone. Alone the rsync
--delete parameter is sent, useful for cleaning the remote directory (when -R
is used together with other flags, it is not). Also see --scp. Alias -R

*-S*
see --sisupod

*-S [filename/wildcard]*
see --sisupod

*-s [filename/wildcard]*
see --source

*--sample-search-form [--db-(pg|sqlite)]*
generate examples of (naive) cgi search form for /SQLite/ or PgSQL depends on
your already having used sisu to populate an /SQLite/ or PgSQL database, (the
/SQLite/ version scans the output directories for existing sisu_sqlite
databases, so it is first necessary to create them, before generating the
search form) see --sqlite & --pg and the database section below. Optional
additional parameters: --db-user='www-data'. The samples are dumped in the
present work directory which must be writable, (with screen instructions given
that they be copied to the cgi-bin directory). Alias -F

*--sax [filename/wildcard/url]*
see --xml-sax

*--scp [filename/wildcard]*
copies sisu output files to remote host using scp. This requires that
sisurc.yml has been provided with information on hostname and username, and
that you have your "keys" and ssh agent in place. Also see --rsync. Alias -r

*--sha256*
set hash digest where used to sha256

*--sha512*
set hash digest where used to sha512

*--sqlite-[instruction] [filename]*
database type set to /SQLite/, this produces one of two possible databases,
without additional database related instructions it produces a discreet
/SQLite/ file for the document processed; with additional instructions it
produces a common /SQLite/ database of all processed documents that (come from
the same document preparation directory and as a result) share the same output
directory base path (possible instructions include: --sqlite-createdb;
--sqlite-create; --sqlite-dropall; --sqlite-import [filename]; --sqlite-update
[filename]; --sqlite-remove [filename]); see database section below.

*--sisupod*
produces a sisupod a zipped sisu directory of markup files including sisu
markup source files and the directories local configuration file, images and
skins. Note: this only includes the configuration files or skins contained in
./_sisu not those in ~/.sisu -S [filename/wildcard] option. Note: (this option
is tested only with zsh). Alias -S

*--sisupod [filename/wildcard]*
produces a zipped file of the prepared document specified along with associated
images, by default named sisupod.zip they may alternatively be named with the
filename extension .ssp This provides a quick way of gathering the relevant
parts of a sisu document which can then for example be emailed. A sisupod
includes sisu markup source file, (along with associated documents if a master
file, or available in multilingual versions), together with related images and
skin. *SiSU* commands can be run directly against a sisupod contained in a
local directory, or provided as a url on a remote site. As there is a security
issue with skins provided by other users, they are not applied unless the flag
--trust or --trusted is added to the command instruction, it is recommended
that file that are not your own are treated as untrusted. The directory
structure of the unzipped file is understood by sisu, and sisu commands can be
run within it. Note: if you wish to send multiple files, it quickly becomes
more space efficient to zip the sisu markup directory, rather than the
individual files for sending). See the -S option without [filename/wildcard].
Alias -S

*--source [filename/wildcard]*
copies sisu markup file to output directory. Alias -s

*--strict*
together with --html, produces more w3c compliant html, for example not having
purely numeric identifiers for text, the location object url#33 becomes url#o33

*-T [filename/wildcard (*.termsheet.rb)]*
standard form document builder, preprocessing feature

*-t [filename/wildcard]*
see --txt

*--texinfo [filename/wildcard]*
produces texinfo and info file, (view with pinfo). Alias -I

*--textile [filename/wildcard/url]*
textile smart text (not available)

*--txt [filename/wildcard]*
produces /plaintext/ with Unix linefeeds and without markup, (object numbers
are omitted), has footnotes at end of each paragraph that contains them [ -A
for equivalent dos (linefeed) output file] [see -e for endnotes]. (Options
include: --endnotes for endnotes --footnotes for footnotes at the end of each
paragraph --unix for unix linefeed (default) --msdos for msdos linefeed). Alias

also see -U

*--urls [filename/wildcard]*
prints url output list/map for the available processing flags options and
resulting files that could be requested, (can be used to get a list of
processing options in relation to a file, together with information on the
output that would be produced), -u provides url output mapping for those flags
requested for processing. The default assumes sisu_webrick is running and
provides webrick url mappings where appropriate, but these can be switched to
file system paths in sisurc.yml. Alias -U

*-V*
on its own, provides *SiSU* version and environment information (sisu --help
env)

*-V [filename/wildcard]*
even more verbose than the -v flag.

*-v*
on its own, provides *SiSU* version information

*-v [filename/wildcard]*

error messages if any), as with -u flag provides a url mapping of files created
for each of the processing flag requests. Alias -v

*--very-verbose [filename/wildcard]*
provides more verbose output of what is being generated. See --verbose. Alias
-V

*--version*
sisu version

*-W*
see --webrick

*-w [filename/wildcard]*
see --concordance

*--webrick*
starts ruby' s webrick webserver points at sisu output directories, the default
port is set to 8081 and can be changed in the resource configuration files.
[tip: the webrick server requires link suffixes, so html output should be
created using the -h option rather than -H ; also, note -F webrick ]. Alias -W

sisu_manifest. --sitemaps generates/updates the sitemap index of existing
sitemaps. (Experimental, [g,y,m announcement this week])

*-y [filename/wildcard]*
see --manifest

*-Z [filename/wildcard]*
see --zap

*--zap [filename/wildcard]*
Zap, if used with other processing flags deletes output files of the type about
to be processed, prior to processing. If -Z is used as the lone processing
related flag (or in conjunction with a combination of -[mMvVq]), will remove
the related document output directory. Alias -Z

COMMAND LINE MODIFIERS
----------------------

*--no-ocn*
[with --html --pdf or --epub] switches off /object citation numbering/. Produce
output without identifying numbers in margins of html or /LaTeX//pdf output.

*--no-annotate*
strips output text of editor endnotes[^*1] denoted by asterisk or dagger/plus
sign

*--no-asterisk*
strips output text of editor endnotes[^*2] denoted by asterisk sign

*--no-dagger*
strips output text of editor endnotes[^+1] denoted by dagger/plus sign

DATABASE COMMANDS
-----------------

*dbi - database interface*

*--pg or --pgsql* set for /PostgreSQL/ *--sqlite* default set for /SQLite/ -d
is modifiable with --db=[database type (PgSQL or /SQLite/) ]

*--pg -v --createall*
initial step, creates required relations (tables, indexes) in existing
/PostgreSQL/ database (a database should be created manually and given the same
name as working directory, as requested) (rb.dbi) [ -dv --createall /SQLite/
equivalent] it may be necessary to run sisu -Dv --createdb initially NOTE: at
the present time for /PostgreSQL/ it may be necessary to manually create the
database. The command would be 'createdb [database name]' where database name
would be SiSU_[present working directory name (without path)]. Please use only
alphanumerics and underscores.

*--pg -v --import*
[filename/wildcard] imports data specified to /PostgreSQL/ db (rb.dbi) [ -dv
--import /SQLite/ equivalent]

*--pg -v --update*
[filename/wildcard] updates/imports specified data to /PostgreSQL/ db (rb.dbi)
[ -dv --update /SQLite/ equivalent]

*--pg --remove*
[filename/wildcard] removes specified data to /PostgreSQL/ db (rb.dbi) [ -d
--remove /SQLite/ equivalent]

*--pg --dropall*
kills data" and drops (/PostgreSQL/ or /SQLite/) db, tables & indexes [ -d
--dropall /SQLite/ equivalent]

The -v is for verbose output.

COMMAND LINE WITH FLAGS - BATCH PROCESSING
..........................................

In the data directory run sisu -mh filename or wildcard eg. "sisu -h cisg.sst"
or "sisu -h *.{sst,ssm}" to produce html version of all documents.

Running sisu (alone without any flags, filenames or wildcards) brings up the
interactive help, as does any sisu command that is not recognised. Enter to
escape.

INTRODUCTION TO SISU MARKUP[^3]
-------------------------------

SUMMARY
.......

*SiSU* source documents are /plaintext/ (/UTF-8/)[^4] 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.

MARKUP RULES, DOCUMENT STRUCTURE AND METADATA REQUIREMENTS
..........................................................

minimal content/structure requirement:

[metadata]

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:

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~)

- 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)

MARKUP EXAMPLES
...............


----------------------------------------

ONLINE
......

Online markup examples are available together with the respective outputs
produced from <https://git.sisudoc.org/sisu-markup> or from

There is of course this document, which provides a cursory overview of sisu
markup and the respective output produced:

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


----------------------------------------

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

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:

% this would be a comment

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.

MARKUP OF SUBSTANTIVE TEXT
--------------------------

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

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)

_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.

HANGING INDENTS
...............

*markup example:*

_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

*resulting output:*

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

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:*

~{ a footnote or endnote }~

*resulting output:*

[^5]

*markup example:*

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

*resulting output:*

normal text[^6] 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 plus symbol footnote/endnote series ]~ continues

*resulting output:*

normal text [^*3] continues

normal text [^+2] 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

LINKS
.....


----------------------------------------

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:*

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

*resulting output:*

normal text <https://www.sisudoc.org/> continues

An escaped url without decoration

*markup example:*

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

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

*resulting output:*

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

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


----------------------------------------

LINKING TEXT
............

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

*markup example:*

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

*resulting output:*

about SiSU [link: <https://www.sisudoc.org/>] markup

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

*markup example:*

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

*resulting output:*

about SiSU [link: <https://www.sisudoc.org/>] [^7] 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:*

about *SiSU* book markup examples


----------------------------------------

LINKING IMAGES
..............

*markup example:*

{ tux.png 64x80 }image

% various url linked images
[image: "a better way"]
 [image: "Way Better - with Gnu/Linux, Debian and Ruby"]

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

*resulting output:*

tux.png 64x80 [link: local image]

tux.png 64x80 "Gnu/Linux - a better way" [link: <https://www.sisudoc.org/>]

GnuDebianLinuxRubyBetterWay.png 100x101 "Way Better - with Gnu/Linux, Debian
and Ruby" [link: <https://www.sisudoc.org/>]

ruby_logo.png 70x90 "Ruby" [link: <https://www.ruby-lang.org/en/>] [^8]

*linked url footnote shortcut*

{~^ [text to link] }https://url.org

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

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.

GROUPED TEXT / BLOCKED TEXT
...........................

There are two markup syntaxes for blocked text, using curly braces or using
tics


----------------------------------------

BLOCKED TEXT CURLY BRACE SYNTAX
...............................

at the start of a line on its own use name of block type with an opening curly
brace, follow with the content of the block, and close with a closing curly
brace and the name of the block type, e.g.

code{
this is a code block

}code

poem{

this here is a poem

}poem


----------------------------------------

BLOCKED TEXT TIC SYNTAX
.......................

``` code
this is a code block

```

``` poem

this here is a poem

```

start a line with three backtics, a space followed by the name of the name of
block type, follow with the content of the block, and close with three back
ticks on a line of their own, e.g.


----------------------------------------

TABLES
......

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 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

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:*

ADDITIONAL BREAKS - LINEBREAKS WITHIN OBJECTS, COLUMN AND PAGE-BREAKS
.....................................................................


----------------------------------------

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.

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

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.


----------------------------------------

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 =\= breaks the page, starts a new page.

page break -\- 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:

-\\-

page (break) new:

=\\=

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

BIBLIOGRAPHY / REFERENCES
.........................

There are three ways to prepare a bibliography using sisu (which are mutually
exclusive): (i) manually preparing and marking up as regular text in sisu a
list of references, this is treated as a regular document segment (and placed
before endnotes if any); (ii) preparing a bibliography, marking a heading level
1~!biblio (note the exclamation mark) and preparing a bibliography using
various metadata tags including for author: title: year: a list of which is
provided below, or; (iii) as an assistance in preparing a bibliography, marking
a heading level 1~!biblio and tagging citations within footnotes for inclusion,
identifying citations and having a parser attempt to extract them and build a
bibliography of the citations provided.

For the heading/section sequence: endnotes, bibliography then book index to
occur, the name biblio or bibliography must be given to the bibliography
section, like so:

1~!biblio


----------------------------------------

A MARKUP TAGGED METADATA BIBLIOGRAPHY SECTION
.............................................

Here instead of writing your full citations directly in footnotes, each time
you have new material to cite, you add it to your bibliography section (if it
has not been added yet) providing the information you need against an available
list of tags (provided below).

The required tags are au: ti: and year: [^10] an short quick example might be
as follows:

1~!biblio

au: von Hippel, E.
ti: Perspective: User Toolkits for Innovation
lng: (language)
jo: Journal of Product Innovation Management
vo: 18
ed: (editor)
yr: 2001
note:

id: vHippel_2001
% form:

note:
sn: Benkler, /{Wealth of Networks}/ (2006)
id: Benkler2006

au: Quixote, Don; Panza, Sancho
ti: Taming Windmills, Keeping True
jo: Imaginary Journal
yr: 1605
url: https://en.wikipedia.org/wiki/Don_Quixote
note: made up to provide an example of author markup for an article with two authors
sn: Quixote & Panza, /{Taming Windmills}/ (1605)
id: quixote1605

Note that the section name !biblio (or !bibliography) is required for the
bibliography to be treated specially as such, and placed after the
auto-generated endnote section.

Using this method, work goes into preparing the bibliography, the tags author
or editor, year and title are required and will be used to sort the
bibliography that is placed under the Bibliography section

The metadata tags may include shortname (sn:) and id, if provided, which are
used for substitution within text. Every time the given id is found within the
text it will be replaced by the given short title of the work (it is for this
reason the short title has sisu markup to italicize the title), it should work
with any page numbers to be added, the short title should be one that can
easily be used to look up the full description in the bibliography.

The following footnote~{ quixote1605, pp 1000 - 1001, also Benkler2006 p 1. }~

would be presented as:

Quixote and Panza, /Taming Windmills/ (1605), pp 1000 - 1001 also, Benkler,
/Wealth of Networks/, (2006) p 1 or rather[^11]

TAGGING CITATIONS FOR INCLUSION IN THE BIBLIOGRAPHY
...................................................

Here whenever you make a citation that you wish be included in the
bibliography, you tag the citation as such using special delimiters (which are
subsequently removed from the final text produced by sisu)

Here you would write something like the following, either in regular text or a
footnote

See .: Quixote, Don; Panza, Sancho /{Taming Windmills, Keeping True}/ (1605) :.

*SiSU* will parse for a number of patterns within the delimiters to try make
out the authors, title, date etc. and from that create a Bibliography. This is
more limited than the previously described method of preparing a tagged
bibliography, and using an id within text to identify the work, which also
lends itself to greater consistency.

GLOSSARY
........

Using the section name 1~!glossary results in the Glossary being treated
specially as such, and placed after the auto-generated endnote section (before
the bibliography/list of references if there is one).

The Glossary is ordinary text marked up in a manner deemed suitable for that
purpose. e.g. with the term in bold, possibly with a hanging indent.

1~!glossary

_0_1 *{GPL}* An abbreviation that stands for "General Purpose License." ...

_0_1 [provide your list of terms and definitions]

In the given example the first line is not indented subsequent lines are by one
level, and the term to be defined is in bold text.

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.

  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+2|second sub-term;
    Another 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,
  Another term, 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/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.

SUBSTITUTIONS
-------------

*markup example:*

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}*'

*resulting output:*

The current *Debian* is *Jessie* the next debian will be *Stretch*

Configure substitution in _sisu/sisu_document_make
