Is there a way to use IntelliJ as a Java/JSP editor without having to create a project and still get some basic support like smart-completion from JDK etc.? Quite often I need to edit a single file when IntelliJ is not running already. To open intelliJ and a project takes 4-5 mins and lot of memory. This forces me to use vi/emacs/ultra-edit etc. as the editor but these editors do not do smart completion etc. as well as IDEA (surprise surprise)
What I would like to do is open intellij, not load a project, open a file and be able to get basic support such as JDK smart completion e.g.
String s = "Hello World";
String s1 = s.sub<ctrl+space>
Is this possible today? How can I do this?
