How to set compilation flags/qualifiers?

I have the following problem:

  • There are several classes with method generators, which needs to be compiled during every compilation
  • I have "ckub" qualifiers enabled in studio
  • I don't want to remove "u" qualifier because I need it very much in another namespaces

So how do I force classes with method generators to recompile when "u" qualifier is present?

Currently I solved this problem by setting studio qualifiers setting to "cukb /checkuptodate=expandedonly" which solved my problem, but I'd like some clarification as to why it helped. Here's  checkuptodate qualifier description:

Name: /checkuptodate
Description: Skip classes or expanded classes that are up-to-date.
Type: enum
Enum List: none,all,expandedonly,0,1
Default Value: expandedonly
Present Value: all
Negated Value: none


  1. What is an "expanded class"?
  2. Why explicitly setting /checkuptodate=expandedonly forces classes with generators to compile every time?
  3. Is there any other, cleaner way to force classes with generators to compile every time?

Not answering your questions, but are you aware of the SetFlags and SetQualifiers methods of %SYSTEM.OBJ ? These can be used to set namespace-specific defaults as well as systemwide defaults. Maybe they'll let you ensure "u" behaviour for certain namespaces even if you remove the "u" flag from Studio's settings.

I need "u" flag in studio. During compilation the flags from user (studio) are combined with namespace or system flags. So even if I set namespace default flags without "u", the compiler would still use this flag as it is present in studio.
