ASCIIMathML plugin

ASCIIMathML is a layer of JavaScript functions to convert ASCII math notation to Presentation MathML. The conversion is done while the (X)HTML page loads, and should work with Firefox/Mozilla/Netscape 7+ and Internet Explorer 6+ (Note: IE6+ requires Mathplayer to properly render the math notations).

ASCIIMathML plugin is based on version 1.4.8 Aug 30, 2007, © ASCIIMathML. This plugin does not support the Latest version of ASCIIMathML. For changes see ASCIIMath Changes.txt.

1. Download the source archive (~14k)from ASCIIMathML - Plugin
2. Unpack it in your Doku­Wiki plugins directory {dokuwiki}/lib/plugins; this will create the following folder:

• {dokuwiki}/lib/plugins/asciimathml.

The folder shall contain the following files

• ASCIIMathML148.js
• plugin.info.txt
• README
• script.js
• syntax.php

That's it!

• For inline formula and when you don't want to start a div!

 <acm> ASCII Math Notation goes here </acm>

• Formula rendered as a new paragraph

 <acmath> ASCII Math Notation goes here </acmath>

This is the syntax for the tag that inserts the MathML presentation on the wiki page. For detailed discussion take a look at ASCIIMathML Syntax.

There are many examples under ASCIIMathML samples. Here are some examples tested under DokuWiki, simply copy paste them into a wiki page with installed ASCIIMathML plugin.

==== Example 1 ====
  * A simple example
<acm>
   f(x)=sum_(n=0)^oo(f^((n))(a))/(n!)(x-a)^n
</acm>

==== Example 2 ====
Matrices and column vectors are simple to type
<acmath>
 [[a ,  b ],[c,  d]]((n),(k))
</acmath>

==== Example 3 ====
Grouping brackets don't have to match
<acmath>
(a,b]={x in RR | a < x <= b}
</acmath>

==== Example 4 ====
piecewise defined function are based on matrix notation
<acmath>
x/x={(1,if x!=0),(text{undefined},if x=0):}
</acmath>

==== Example 5 ====
Complex subscripts are bracketed, displayed under lim
<acmath>
(df(x))/dx=lim_(h->0)(f(x+h)-f(x))/h
</acmath>

==== Example 6 ====
  * A multi-lines formula
<acm> int (x+1)(e^(x//2) - 1) dx = (x+1)(2e^(x//2) - x)- int (2e^(x//2)-x) dx</acm>

<acm> \ \ \ \ =(x+1)(2e^(x//2) - x) - (4e^(x//2) - x^2/2) + C</acm>

<acm> \ \ \ \ = 2xe^(x//2) -x^2 + 2e^(x//2) -x - 4e^(x//2) + x^2/2 + C</acm>

<acm> \ \ \ \ = 2e^(x//2)(x-1)-x-x^2/2 + C</acm>



==== Example 7 ====
  * Prescripts simulated by subsuperscripts
<acmath>
{::}_(\ 92)^238U
</acmath>


  * Symbols can be stacked
<acmath>
 stackrel"def"= or \stackrel{\Delta}{=}" "("or ":=)
</acmath>


  * Accents can be used on any expression 
<acmath>
 hat(ab) bar(xy) ulA vec v dotx ddot y
</acmath>

You can try ASCIIMathML online here at ASCIIMathML.js sandbox.

• The ASCIIMathML was implemented as a pseudo plugin here. It seems the plugin simply adds the ASCIIMathML.js into DokuWiki. There is PHP port for ASCIIMathML, it seems a PHP version of ASCIIMathML is a better solution.
• Interested developers are invited to correct/modify the code to obey the DokuWiki rules and for better performance.
• To support the latest version of ASCIIMathML which has graphics capability like asciisvg.

1. Nothing reported by now!

This is a very nice plugin, when you can have it running…

• You can decide to patch the asciimathml/ASCIIMathML148.js file to support Opera and other recent browsers, like this:

function AMisMathMLavailable() {
  if (navigator.appName.slice(0,8)=="Netscape")
    if (navigator.appVersion.slice(0,1)>="5") return null;
    else return AMnoMathMLNote();
  else if (navigator.appName.slice(0,9)=="Microsoft")
    try {
        var ActiveX = new ActiveXObject("MathPlayer.Factory.1");
        return null;
    } catch (e) {
        return AMnoMathMLNote();
    }
// Opera support for MathML
  else if (navigator.appName=="Opera")
    return null;
  else return AMnoMathMLNote();
}
