Hi, what do you mean exactly by "work on eclipse while displaying output"? You want to use the regex in a scanner/lexer/seeder in an analysis engine in a Ruta project in the Ruta Workbench?
Here's how to modify the SeedLexer implementation: - modify/extend SeedLexer.flex with your regexp - download jflex 1.4.3 from http://jflex.de/ - start the gui of jflex and generate the java class for SeedLexer.flex - build the complete ruta reactor project Then, it depends on what you want to do. You could either start the Workbench from within Eclipse or you can generate a new update site for installing the changed plugins in your eclipse. However, I assume that there is a much easier way to achieve your goal. Do you want to describe your use case? You could maybe just write a simple regexp ruta rule like "<+" -> TAG; MARKUP{PARTOF(TAG)-> UNMARK(MARKUP)}; Best, Peter Am 05.02.2016 um 12:47 schrieb AmyJacksonKatrina: > i just want add some regex rules in seed.flex files which should work on > eclipse while displaying output.
