00:27 <egg|laptop|egg> lamont: if you want to toy with things you can try the eggrobin/lamont-endpoints branch

00:27 <egg|laptop|egg> it has a completely untested implementation of ExternalGetNearestPlannedCoastDegreesOfFreedom

00:28 <egg|laptop|egg> but you can try getting the reflection plumbing together and calling it if you feel lucky

00:29 <egg|laptop|egg> lamont: obviously this the details of the function signature may change, for instance I'm considering returning an {error code, string} struct rather than return error code out string, but the general principle should be the same

00:33 <lamont> cool

00:33 <lamont> still got work-work i’m working on...

00:34 <egg|laptop|egg> yeah, speaking of this I should sleep :-p

00:34 <awang> egg|laptop|egg: Want me to add both TEMPLATE and TYPENAME?

00:35 <egg|laptop|egg> nah just TEMPLATE

00:35 <awang> Alright

00:35 <egg|laptop|egg> we'll readd TYPENAME if we need it

00:35 <awang> Does it matter where in macros.hpp I put it?

02:48 <awang> egg|anbo|egg: I like the #errors in macros.hpp

02:52 <awang> egg|anbo|egg: Also, what _MSC_VER should I test for?

08:08 <GH> [Principia] eggrobin commented on issue #1702: Another alternative is to change the declaration to `typename FixedMatrix::template Row<r>`, which should deconfuse MSVC; see https://godbolt.org/g/awXGmV. https://git.io/vNdzD

09:57 <GH> [Principia] pleroy commented on issue #1702: I interpret the last section of [this article on cppreference](http://en.cppreference.com/w/cpp/language/dependent_name) as saying that (1) `template` is required on the definition and (2) `template` is permitted on the declaration, where it is unnecessary. I vote for @eggrobin 's fix. https://git.io/vNd6y

15:37 <egg|laptop|egg> I'm not sure what this question means

15:39 <UmbralRaptor> As opposed to doing n-body outside of KSP?

20:30 <lamont> (click the link — i’m making fun of your UTF manœuvres

20:30 <lamont> “what are you, a bloody tank commander now?”

20:32 <egg|laptop|egg> heh

20:33 <egg|laptop|egg> lamont: yeah, but that allows to disambiguate the terminology, you see, stock has maneuver nodes, and we have manœuvres :-p

20:33 <lamont> indeed

20:33 <lamont> you have invented a manœuvre

22:05 <egg|laptop|egg> !wpn

22:06 <egg|laptop|egg> lamont: I updated the lamont-endpoints branch, the functions now return a Status struct. This struct currently just contains an int error, eventually I'll give you an error message there too

22:06 <egg|laptop|egg> for now I just log it

22:06 <egg|laptop|egg> (at the ERROR severity so you should see it in stderr too)

22:09 <GH> [Principia] eggrobin commented on issue #1704: This breaks `mercury_perihelion_test`, which is weird. https://git.io/vNbqF

22:23 <GH> [Principia] eggrobin commented on issue #1704: Ah nevermind, this is not a test that actually uses Prolong, so it is polynomial evaluation + Cartesian to Keplerian conversion; the error of the former went up as expected. https://git.io/vNbO2

22:34 <awang> I should find a way to build the benchmarks on mac

22:34 <awang> And see if I can duplicate the separate dll thing

22:34 <awang> I think I know how to do that using CMake, but adding yet another build system doesn't sound like a good idea

22:34 <awang> As gross as Makefiles are

22:34 <awang> I should also figure out PGO on mac

22:41 <egg|laptop|egg> awang: we're overhauling the way we do PGO on windows

22:41 <egg|laptop|egg> so maybe it's not the best time to do that

22:42 <awang> Ah, ok

22:42 <awang> Is the overhaul the split into multiple libraries thing?

22:42 <egg|laptop|egg> yup

22:42 <egg|laptop|egg> but that might not be needed with clang

22:42 <awang> Hm

22:43 <awang> Why was it necessary for MSVC again?

22:43 <egg|laptop|egg> it's because MSVC's PGO implies LTO

22:43 <awang> I know you said it, but I forgot

22:43 <egg|laptop|egg> so PGO optimizes a whole DLL, not a static lib

22:43 <egg|laptop|egg> whereas clang is happy to PGO a static lib iirc

22:43 <egg|laptop|egg> except it might be called FDO or something

22:44 <awang> Hmmm
