             Summary: Autocompleation uses very outdated data
                 Key: JBIDE-20386
                 URL: https://issues.jboss.org/browse/JBIDE-20386
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: freemarker
            Reporter: Daniel Dekany


When you press Ctrl+Space after {{<#}} or in an expression after {{foo?}}, the list of directive names, and especially the list of built-in names shown is very outdated. Instead of maintaining these lists manually, the list of directive names could be get from {{freemarker.template.Configuration.getSupportedBuiltInDirectiveNames()}}, and the list of built-in names from {{Configuration.getSupportedBuiltInNames()}}.

Some complication since 2.3.23 is that the list of names should be filtered based on {{Template.getActualNamingConvention()}} (which either returns {{Configuration.LEGACY_NAMING_CONVENTION}} or {{Configuration.CAMEL_CASE_NAMING_CONVENTION}}). Though the algorithm for that is simple: If a name contains upper case letter then it's camel case. Otherwise, if it contains {{_}} then it belongs to the legacy naming convention. Otherwise if it's a directive name that equals to a lower-cased camel case directive name, then it's legacy naming convention (consider {{elseIf}} VS {{elseif}}). Otherwise the name belongs to both naming conventions.
