How to Run JEuclid "foprep" Command on macOS?

✍: FYIcenter

A

"foprep" is a command provided in JEuclid 3.1.9 that allows you to render MathML documents embedded in XSL-FO or XHTML files to SVG documents.

This helps XSL-FO processors or XHTML browsers that do not support MathML to view rendered math formulas as SVG documents.

You can follow these steps to run "foprep" command.

1. Create an XHTML document with a MathML document embedded inside and save it as JEuclid-MathML-Example-3-in-XHTML.xhtml.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<h4>MathML Document Embedded Below:</h4>

<math xmlns="http://www.w3.org/1998/Math/MathML" 
  mode="display" overflow="scroll">
  <mrow>
    <mo>(</mo>
    <mtable>
      <mtr>
        <mtd columnalign="center">
          <mrow>
            <mo>(</mo>
            <mtable>
              <mtr>
                <mtd columnalign="center">
                  <mi>a</mi>
                </mtd>
                <mtd columnalign="center">

</math>

</body>
</html>

2. Run "foprep" command to replace embedded MathML documents with SVG documents.

fyicenter$ export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_341.jdk/Contents/Home

fyicenter$ ~/Applications/jeuclid-3.1.9/bin/foprep \
  -in JEuclid-MathML-Example-3-in-XHTML.xhtml -out output.xhtml

3. Review the generated file output.xhtml.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<h4>MathML Document Embedded Below:</h4>

<svg xmlns="http://www.w3.org/2000/svg" 
  color-interpolation="auto" color-rendering="auto" contentScriptType="text/ecmascript" 
  contentStyleType="text/css" fill="black" fill-opacity="1" font-family="'Dialog'" 
  font-size="12" font-style="normal" font-weight="normal" height="59" 
  image-rendering="auto" preserveAspectRatio="xMidYMid meet" shape-rendering="auto" 
  stroke="black" stroke-dasharray="none" stroke-dashoffset="0" stroke-linecap="square"

  text-rendering="auto" version="1.0" width="68" zoomAndPan="magnify">

  <defs id="genericDefs"/>
  <g><g color-interpolation="linearRGB" color-rendering="optimizeQuality" 
    image-rendering="optimizeQuality" text-rendering="optimizeLegibility" 
    transform="translate(-0.5508,46.4629) matrix(1,0,0,5.6552,0,0)">
    <path d="M1.7695 -6.5918 Q2.5195 -7.5352 3.5391 -8.1094 L3.6504 -7.916 Q2.707 ...
    ...
  </g></g>
</svg>

</body>
</html>

4. Open both JEuclid-MathML-Example-3-in-XHTML.xhtml and output.xhtml in a Web browser that supports MathML and SVG. The output shows that the output rendered by JEuclid is smaller with thinner strokes. But you can make it bigger by inserting a <mstyle fontsize="16"> container element.
