| 20:02.39 | brlcad | starseeker: if you would, see if that works |
| 20:02.49 | brlcad | think it was just missing a couple spaces |
| 20:04.05 | starseeker | brlcad: OK - that did work, but the function definition took only a single const char * so I wasn't sure about passing in multiple strings |
| 20:04.44 | starseeker | didn't know if the spaces had been left out deliberately for that reason... |
| 20:09.06 | brlcad | it's not passing multiple strings |
| 20:09.20 | brlcad | that's how C works |
| 20:09.46 | brlcad | e.g., try something like this: printf("hello" " my name " "is" " cliff"); |
| 20:10.11 | brlcad | that's one arg to printf |
| 20:10.21 | starseeker | ah - the compiler handles merging them? |
| 20:10.34 | brlcad | automatic string concatenation is a feature of the language often not taught/encountered very often |
| 20:11.24 | brlcad | only works with static strings |
| 20:11.42 | starseeker | nods |
| 20:11.45 | brlcad | the error from msvc is a pedantic one about smashing a cpp symbol right up against a string literal |
| 20:13.17 | brlcad | #define BAR "bar" ; printf("foo"BAR); vs printf("foo" BAR); vs printf("foo""bar"); vs printf("foo" "bar"); |
| 20:13.52 | Notify | 03BRL-CAD:starseeker * 67320 brlcad/trunk/misc/tools/xmltools/libxslt/config.h.in: one more stdio include for snprintf on MSVC |
| 20:13.53 | brlcad | don't know what the spec actually says, but my understanding was that one should separate them with whitespace |
| 20:14.05 | starseeker | nods - certainly more readable |
| 20:14.13 | brlcad | even if it works, which apparently it did |
| 20:14.58 | brlcad | we actually use string concat in a lot of places |
| 20:16.17 | brlcad | 41 places apparently |
| 20:16.47 | starseeker | brlcad: did you see my note about interactive mode? |
| 20:17.39 | starseeker | kinda things that would make sense to have as the default mode to use with Archer's "raytrace" button, actually... |
| 20:17.48 | starseeker | s/things/thinks/ |
| 20:19.04 | starseeker | needs to do a little more osgl vs ogl debugging to see why the initial window paint isn't working in MGED, but may be closing in on "no known problems" for osgl dm once that's done... |
| 20:20.12 | starseeker | will have to see about re-enabling the Aqua+OSGL non-X11 Mac build and see about Windows behavior |
| 20:20.35 | brlcad | sounds good to me, but beware that incremental mode is usally slower by some percentage, 5-25% iirc |
| 20:20.50 | brlcad | you certainly get the gist more quickly, but end-to-end will take longer |
| 20:21.05 | starseeker | nods - maybe as an Archer setting then |
| 20:21.24 | brlcad | and especially the last pass where it converges the final 2x2's into 1x1's ... that can seemingly take forever |
| 20:21.51 | starseeker | yeah, probably should be user settable |
| 20:22.20 | starseeker | brlcad: did you have a specific sense where interactive mode needed to be tested? (i.e. Windows?) |
| 20:22.32 | starseeker | aside from the terminally slow in ogl thing, it looked OK on Linux |
| 20:23.10 | brlcad | no, my commit message wasn't as detailed as it should have been |
| 20:23.24 | brlcad | I recall reviewing a patch that deleted code for one of the modes |
| 20:23.51 | brlcad | maybe it was for -I instead of -i, because -I seems pretty pointless to me right now |
| 20:24.01 | starseeker | concurs |
| 20:24.01 | brlcad | waste of a letter |
| 20:24.06 | starseeker | indeed |
| 20:24.18 | starseeker | maybe mattered more back in PDP11 days... |
| 20:24.20 | brlcad | with that, the todo makes more sense |
| 20:24.30 | brlcad | it mattered in the early 90's |
| 20:24.47 | starseeker | votes we deprecate it and call it done... |
| 20:25.21 | starseeker | longopt or cc= the feature if it's still useful, but definitely not -I |
| 20:25.42 | brlcad | the todo still worries |
| 20:25.53 | brlcad | basically that -I used to do more and someone removed whatever it was doing |
| 20:26.05 | brlcad | which is what makes it seem so lame now |
| 20:26.20 | starseeker | brlcad: if so, it looks like it was before your big code reorg in the 22000 days |
| 20:26.33 | brlcad | I noticed enough that made me add the entry |
| 20:26.44 | brlcad | no, that todo was really recent .. I remember adding it |
| 20:26.59 | starseeker | no, I mean the -I feature |
| 20:27.01 | brlcad | just didn't say which commit caused me to note it |
| 20:27.14 | brlcad | huh? |
| 20:27.19 | brlcad | I know it's an old flag |
| 20:27.29 | brlcad | I'm suggesting that the flag used to do more than renice the app |
| 20:27.46 | starseeker | the -I feature setting the nice value - if -I ever did more than that, it was before the 22000 commit range when you did the big reorg |
| 20:27.47 | brlcad | someone probably removed the code for whatever it was that it did |
| 20:27.50 | starseeker | i.e. a *long* time ago |
| 20:27.57 | brlcad | no, that's my point |
| 20:28.13 | brlcad | I recall writing that todo, because I was reviewing a recent patch |
| 20:28.22 | brlcad | s/patch/commit/ |
| 20:28.26 | starseeker | hmm. |
| 20:28.42 | starseeker | if you look at svn blame for the -I code, I think it goes a long way back... |
| 20:28.51 | starseeker | did that one evening |
| 20:29.06 | brlcad | sure, the option goes way back ... still not the point :) |
| 20:29.12 | starseeker | heh |
| 20:29.28 | brlcad | if all it's ever done was renice, then I agree -- but that's the entire question |
| 20:29.36 | brlcad | the todo suggests otherwise |
| 20:29.53 | brlcad | we can still deprecate the flag |
| 20:29.59 | starseeker | nods - that's why I was looking in the history to see if it ever did anything else |
| 20:30.23 | brlcad | but assuming it did do something, we may end up effectively shipping a broken flag |
| 20:30.30 | brlcad | not doing what it used to |
| 20:32.30 | starseeker | woo hoo! Successful MSVC 2015 build, archer comes up |
| 20:32.36 | starseeker | time to test Release build |
| 20:33.11 | starseeker | proceeds to kick off build and run errands... |
| 20:33.21 | starseeker | brlcad: well, let me know if I can help with the -I thing |
| 20:33.29 | brlcad | okay, just checked out a revision before my commit review set and not seeing interactive mode doing anything interesting |
| 20:33.38 | brlcad | so lets just kill it |
| 20:33.45 | starseeker | deprecate, or squash? |
| 20:34.15 | brlcad | technically not user visible on current hardware |
| 20:34.27 | starseeker | works for me |
| 20:35.20 | starseeker | notes that cutting down the number of MSVC targets really pays off when doing this sort of testing... |
| 20:35.26 | brlcad | warrants a news, but yeah I think we can skip deprecation on an technicality |
| 20:37.01 | starseeker | things he'll look at consolidating the tcl index stuff into one target - partial is problematic since you often end up needing pieces that don't get called out in deps |
| 20:37.07 | starseeker | s/things/thinks |
| 20:37.28 | starseeker | grr - haven't even been on thingiverse lately. come on fingers, get with the program... |
| 20:38.26 | starseeker | alrightie, be back later - if this works I'll be able to shut down the Windows VM and get back to osgl debugging |
| 20:38.49 | starseeker | eyes Mac Aqua building... so tempting... |
| 20:39.22 | brlcad | I fixed most of the remaining aqua issues, it almost builds clean out of the box now |
| 20:39.35 | brlcad | if you have osgl working, we should make aqua be default |
