Helper template

If you need to write groovyScripts yourself, the following template may come in handy.
The code below escapes the copied groovyScript for later use in template variables.

groovyScript("def str = _1.replace(\"\\n\", \"\"); while (str.contains(\"  \")) { str = str.replace(\"  \", \" \"); }; str = str.replace(\"\\\"\", \"\\\\\\\"\"); return \"groovyScript(\\\"\"+str+\"\\\")\"", clipboard())
