== Implemented Features ==

 * Article structure with numbered sections and subsections
 * Book structure with preface, numbered chapters, sections and subsections
 * Mathematics: normal LaTeX for PDF, !MathJax in HTML, macros in source '''only once'''
 * Numbered theorems and definitions, with cross-references, even in !MathJax displays
 * Sage input/output: live Sage cells in HTML, styled as text for LaTeX
 * Figures, with numbering and cross-references
 * Basic raster images
 * Bibliography + citations: as knowls in HTML version
 * Navigation (previous/up/next) in HTML (needs just a bit of work)
 * Basic CSS for HTML version

== Files and Commands, the nitty-gritty ==

Updated: August 23, 2013

Prerequisites: {{{xsltproc}}} is in most Linux distributions and on Mac OS as a command-line executable. Information on Windows availablity would be helpful - please write. You'll need TeX to run {{{pdflatex}}}. You can author if you also have a text editor and a browser - that is all you need.
  
HTML output: !MathJax does the math, Sage Cell Server does the code, knowls do the citations. Use the following command and files below to create (X)HTML output and view in your browser by opening the output file.
{{{
xsltproc mathbook-html.xsl calculus-article.xml > calculus-article.html
}}}

PDF: Same XML source file. Use a different XSLT file to process. View PDF as you please. Issue the following to produce.
Line 13: Line 75:
xsltproc article-latex.xsl calculus-article.xml > calculus-article.tex xsltproc mathbook-latex.xsl calculus-article.xml > calculus-article.tex
Line 17: Line 79:
Or you should be able to preview the source file (*.xml) by opening it in a web browser with the stylesheet (*.xsl) in the same directory. More: repeat above with the mock book, {{{graph-theory-book.xml}}}, linked above.

Advanced: create a [[https://cloud.sagemath.com|Sage Cloud]] worksheet from the same source. I have this working in the lab. Posted soon.

Files: Use your browser to save these files locally, do not simply click on them. The XSL files can be scary - not critical for an author to understand them. You'll want the CSS to render any HTML you produce.

== The AQ (Asked Questions) ==

  1. I can't seem to get a matrix into my document.<<BR>>
  It's math so put it inside `<m>` or `<me>` or `<md>` tags and use LaTeX syntax (amsmath package supported). But the ampersand is one of two troublesome special characters in XML, so you need to escape it. Like so
  {{{
<me>\begin{bmatrix} 1 &amp; 2 \\ 3 &amp; 4 \end{bmatrix}</me>
  }}}
  Or you can wrap the whole thing as a CDATA section (which will cause all markup to be ignored). This might be preferable for a big matrix.
  {{{
<me><![CDATA[\begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}]]></me>
  }}}
  1. I have a "less than" in my math which is causing problems.<<BR>>
  The other nasty special character. Use `\lt` instead of `<`.

== To Do (unprioritized) ==

 * Further improve cross-references
 * Table of Contents in HTML as sidebar
 * Index (for book structure)
 * Options for numbering sections, theorem-like structures (hard)
 * Improved CSS for HTML
 * Doctesting framework for Sage code (easy)
 * Sage notebook, Sage Math Cloud output formats
 * Customize level of HTML chunking (one HTML file per section, chapter, etc)
 * Customization options (layers, HTML head insertions)
 * LaTeX spacing hints
 * Figures
 * Tables
 * Exercises
 * Margin paragraphs

== Other Projects ==

 * [[http://tbookdtd.sourceforge.net/|tbook]] looks very much like what I am imagining. I have hacked a bit of it to work with the {{{xsltproc}}} processor with mixed success. Only [[http://tbookdtd.sourceforge.net/dtd/index.html|80 elements]]. But for a very short article, I have found cross-references broken and manufacturing a bibliography begins with BibTeX, so that requires some research (and shell scripts). Maybe some examples later.

 * [[http://www.docbook.org/|DocBook]] is big, complicated and full of features. But the emphasis is on technical documentation and support for mathematics and academic publishing is very lacking. The extensive structure is intimidating if you just have small project.

The AQ (Asked Questions)

  1. I can't seem to get a matrix into my document.
    It's math so put it inside <m> or <me> or <md> tags and use LaTeX syntax (amsmath package supported). But the ampersand is one of two troublesome special characters in XML, so you need to escape it. Like so 

    <me>\begin{bmatrix} 1 &amp; 2 \\ 3 &amp; 4 \end{bmatrix}</me>

    <me><![CDATA[\begin{bmatrix} 1 & 2 \\ 3 & 4 \end{bmatrix}]]></me>

  2. I have a "less than" in my math which is causing problems.
    The other nasty special character. Use \lt instead of <.
