[Rubyeclipse-commit] org.rubypeople.rdt.ui/src/org/rubypeople/rdt/internal/ui/preferences RubyTemplatePreferencePage.java,NONE,1.1

[Christopher W. <caw...@us...>]

Update of /cvsroot/rubyeclipse/org.rubypeople.rdt.ui/src/org/rubypeople/rdt/internal/ui/preferences
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv28822/src/org/rubypeople/rdt/internal/ui/preferences

Added Files:
	RubyTemplatePreferencePage.java 
Log Message:
overhaul our completion proposal/template code. Now we will apply formatting to templates when inserted! Plus we're closer to the way JDT does things. We still can't use the actual code formatter on the templates (because our old one does a massive replace edit which messes up variables like the cursor placement). The end result is that users should create templates with somewhat proper formatting initially.
