Description:

This tag library allows to parse polynomials into OpenMath objects.



Download and Install:

Download:

The whole tag library project is available for dowloading, as tar.gz or as a zip file, here .

General INSTALL information:

This tag library is designed to be used in JSP pages compliant with the JSP 2.0 specification.

To get this tag library working you will have to copy the jar files

Jar fileDownloadDescription
om-lib.jardownloadROML library
expr-parser.jardownloadCan parse algebraic expressions into OpenMath algbraic expressions
antlr-2_7_0.jardownloadNeeded for parsing.
polyparser-taglib.jardownloadThe tag library jar file.

to the WEB-INF/lib/ directory on your web application.

NOTE: We advise you to use the versions of additional jar files comming with the tag library and not to download them directly from other of our related projects. By doing so, you may create imcompatibilities: though we will do our best to make sure a tag library is using the latest version of a jar file.

You will also need to copy the tld file polyparser-taglib.tld to somewhere in the WEB-INF/ directory, for instance to WEB-INF/ itselft, and add to the web.xml file, in the part corresponding to the tag libraries, the following lines: 

<taglib>
    <taglib-uri>URI identifying your tag lib</taglib-uri>
    <taglib-location>/WEB-INF/polyparser-taglib.tld</taglib-location>

</taglib>

For more information on how to modify the web.xml file peruse the documentation coming with your WEB server/container. For information on how to use tag extensions on your own JSP pages consult the JSP 2.0 specification.

Functions


1- dmptostr (function).
Description:

Produces a string representation of a DMP.

Function Class:

nl.tue.win.riaca.taglib.polyparser.PolyParserFunctions

Function Signature:

java.lang.String dmpToStr( java.lang.String )



Examples:
Snippet 1: 
        
            <c:out value="polyparser:dpmtostr(param.a)"/>




2- expand (function).
Description:

Expands and simplifies an Algebraic Expression.

                <c:out value="polyparser:expand(param.a)"/>
            </if>




3- isDMP (function).
Description:
