RUTA: create own extensions

[Nicolas Paris <ni...@gmail.com>]

Hello

My goal is to create a RUTA custom extension that would do in my own UIMA pipeline:
(DateDifferrenceInMonth(Timex3.timexValue, "2018-03-22") - 6 )  {-> DateSixMonthBeforeNow}
*where Timex is an annotation from heideltime for eg


Then I have tried to begin with the examples extensions, and this
tutorial: https://stackoverflow.com/a/22067299/3865083

As stated in the last paragraph, if I want to use this extension in
eclipse, this might be complicated to import all dltk toolkit.

Then as a first attempt I just tried to implement both ExampleCondition and
ExampleConditionExtension and added the
new String[]{"org.apache.uima.ruta.example.extensions.ExampleConditionExtension"}
to the
RutaEngine.PARAM_ADDITIONAL_EXTENSIONS
of my own pipeline.

As a result, when I introduce the ExampleCondition in a ruta script, I get a
org.apache.uima.ruta.extensions.RutaParseRuntimeException 
"(": expected WILDCARD, but found LPAREN

Then, I am missing something ?

Thanks for all,

Hi,


that should actually work just fine as you described. The exception 
indicates that the keyword for the condition is not known.

I'll try to reproduce the problem and get back to you.


Best,


Peter
