The first just fixes some minor errors in the LIST macros. The second cleans up on the MoverBase, making it use the LIST macros. In addition, the order of the arguments on the movers has been changed to make particles last as in the restraints.

IMP_BEGIN_CHECK
by Daniel Russel 15 May '08

15 May '08

As any of you who looked at the syntax may have noticed, the current syntax is a bit evil since you write IMP_BEGIN_CHECK(EXPENSIVE); some stuff which gets controlled by the surrounding statement and is in a nested scope IMP_END_CHECK; We want something that naturally conveys that the surrounded blocks are in a nested scope. One possibility is something like IMP_IF_CHECK(level) which would expand to if (get_check_level() > level) So the user has to add braces to put more than one statement in there. I think I like that better and emacs does the right thing with indenting it. Any thoughts?

ObjectContainer disabling checks
by Daniel Russel 15 May '08

15 May '08

I had missed wrapping one of the checks in ObjectContainer with NDEBUG which made adding large numbers of particles painfully slow. I can't submit a patch since it would conflict with the not yet committed changes. It is simple, the single object insert needs to have its check wrapped with IMP_BEGIN_CHECK(EXPENSIVE); IMP_END_CHECK And the multipartcle check which is currently CHEAP should be made EXPENSIVE.

GravityCenter::set_position...
by Daniel Russel 13 May '08

13 May '08

really shouldn't be called that as we have set_X take a value everywhere else. The method updates the position from its parts and so should be called something more like that.

Stop. Oh, sorry. It should be 'kernel/doc'. Forgot that we moved all the kernel stuff to a subdirectory some time ago. > I haven't used docbook.

Docbook certain went overboard on the markup :-) Indeed - it's XML. The DocBook stuff right now is very basic, because most of today's documentation is API documentation. But once we have less technical users - as is the long term intention - they will need more traditional book-style documentation (of course pointing them to the docbook docs for any technical stuff).
