Scilab documentation format

on line help XML file description format

Description

The on line help source files are written in XML.

Source files (with extension .xml) can be found in the <SCIDIR>/modules/<MODULE NAME>/help/<language>/* directories. The file name is usually associated to a keyword (corresponding to a function name most of the cases) it describes.

A few words about XML

A XML file is similar to a HTML file but with a more rigid syntax. The documentation of Scilab must be written using the strict subset of DocBook 5.1 defined in SCI/modules/helptools/schema/scilab.rng. DocBook 5.1 elements are fully documented in "DocBook 5.1: The Definitive Guide"

Scilab is able to understand a large subset of Docbook tags. However, if any are missing, a bug report can be reported on the Scilab bug tracker.

How to write a simple XML scilab help page:

If one want to write the XML file associated to a new scilab function he or she may use the Scilab function help_skeleton to produce the skeleton of the XML file. In most cases, the user will not be required to know XML syntax.

How to write a simple XML scilab help page: an example

The root element of a document which conforms to the Scilab DocBook 5 subset must have version attribute set to "5.0-subset Scilab".

<?xml version="1.0" encoding="UTF-8"?>
<refentry xmlns:scilab="http://www.scilab.org" xml:id="foo" xml:lang="en"
          xmlns="http://docbook.org/ns/docbook"
          xmlns:xlink="http://www.w3.org/1999/xlink"
          xmlns:svg="http://www.w3.org/2000/svg"
          xmlns:ns4="http://www.w3.org/1999/xhtml"
          xmlns:mml="http://www.w3.org/1998/Math/MathML"
          xmlns:db="http://docbook.org/ns/docbook">

Example:

function y=foo(a, b, c)
   y = a + 2 * b + c;
endfunction

path = help_skeleton('foo', TMPDIR)
if (isdef('editor') | (funptr('editor')<>0)) then
   editor(path);
end

Generated foo.xml in TMPDIR:

How to create a help chapter

Create a directory and write down a set of XML files build as described above. Then start Scilab and execute xmltojar (see xmltojar for more details) .

How to make Scilab know a new help chapter

This can be done by the function add_help_chapter.
