05:30<planetmaker>Is there an easier / better way to unpatch a version than deleting the dir and a clean checkout from svn?
05:34<Rubidium>svn revert?
05:35<planetmaker>hm... doesn't always work, does it?
05:36<Alberth>revert is very careful about not deleting files if that's what you mean
05:36<planetmaker>uh, right. Probably that's it.
05:37<planetmaker>but svn status tells me... (just learning it :) )
05:38<Alberth>also, revert is by default not recursive (try 'svn revert -R .')
05:39<Alberth>if it doesn't work at first, configure it with an option ;)
05:39<Eddi|zuHause3>there's also "patch -R"
05:40<Eddi|zuHause3>but that might fail if you did other modifications
05:40<Alberth>Eddi: I was about to suggest that, but it is for swapped files. Not sure whether it also works for undo-ing patching
05:40<planetmaker>^^that I just looked up but wasn't sure how to understand the man pages...

07:52<Eddi|zuHause3>that sounds fun ;)
08:00<Ammler> <-- a good ctrl usage, better then "just" the fastest from Frostregen and Hotkey doesn't help really, because you have to scroll again...

08:13<SmatZ>I liked the Insert / Home to emulate Left/Right mouse buttons
08:13<SmatZ>I used them a lot :)
08:13<Eddi|zuHause3>yes, and alt+arrow to move the cursor
08:13<Eddi|zuHause3>i used that on the laptop where the trackball was crap
08:14<Eddi|zuHause3>i really miss that feature
08:14<Eddi|zuHause3>arrows to scroll the map is still there
08:15<Eddi|zuHause3>and shift+arrows to go faster

08:26<CIA-3>OpenTTD: depended on the 'querystr_d' object which is now put into QueryStringBaseWindow.
08:26<CIA-3>OpenTTD: As a side effect this removes quite a lot of WP macro usages and a few global

10:04<Rubidium>what revision?
10:04<planetmaker>sorry forgot to mention, Thx. for asking
10:05<planetmaker>I think it prevailed for some time, didn't test thoroughly, though
10:07<Ammller>I have seg faults if cancel it
10:08<planetmaker>hm. I don't...
10:08<planetmaker>(I'm on MacOS, so that might make a difference)

10:10<planetmaker>hehe :)
10:10<planetmaker>Quick and to the point as ever. Thx mate
10:11-!-bowman [] has joined #openttd
10:15<planetmaker>Rubidium: can you give a rough estimate of how much of the struct -> class conversion is done? I just noticed many changes there recently...
10:16<Rubidium>it's not about changing struct -> class
10:17<planetmaker>Hm... my impression was to get more object code into play - and thus clean up some things. But please tell me how far off I am with this impression :)
10:17<Rubidium>it's about removing w->custom, WP(w, xxx), assert_compile(xxx_d <= WINDOW_CUSTOM_SIZE)
10:17<Rubidium>eventually it'll lead to somewhat nice code though
10:18<Alberth>and creating a Window inheritance tree in the process :)
10:18<Alberth>Rubidium: Anything I can do without getting in your way?
10:20<Alberth>(and you not changing and committing code I was looking into... :)
10:20<Rubidium>that's quite doubtful I fear
10:20<Rubidium>we're really touching the window code all over the place
10:21<Rubidium>only thing you can do it testing whether the changed windows still work I guess
10:22<planetmaker>or work on stuff without GUI :)
10:23<CIA-3>OpenTTD: rubidium * r13045 /trunk/src/ (5 files in 2 dirs): -Codechange: make list_d (now GUIList) more generic and uniform.
10:24-!-Zr40 [] has quit [Quit: Zr40]
10:25<Alberth>I tried that too. There are 6 or 7 patches waiting already. I don't dare adding more without getting some comments or commits to trunk.
10:26<planetmaker>you have a link for me, Alberth? (Not that I can make useful comments, but to see :) )
10:28<Alberth>FS#1857, FS#1942, and the WindowOO one: FS#1905
10:29<Alberth>and FS#1762, but Bjarni is also working on that one.
10:31<planetmaker>hm... fs is really slow for me right now :S
10:37<Alberth>Hmm, selection of FS issues on Developer is broken.
10:44<planetmaker>nvm. fs# work well :)
10:46<planetmaker>I especially like FS 1857 :)
10:50<Alberth>Yeh, I thought it was a nice idea from ToiletDuck, so I implemented it. I checked it this morning, it is still mergeable. However, I don't know whether devs agree with the idea.
10:51<planetmaker>Hm, yeah. For what it's worth: you got my support :)

10:52<planetmaker>Though I get the drift of the others, it's internal stuff the people who work daily have to like - or not
10:54<Alberth>At the moment, I am trying to get the hang of code refactoring, making structural changes without breaking anything. It is quite fun, although nobody ever will notice the change.
10:56<planetmaker>:) Make it faster while doing so :)
10:56<Alberth>and sometimes a dev like Rubidium steps in and simply takes over.... :)
10:57<Rubidium>doing the changes I'm currently doing are not what I'd like to get as patches (really unreviewable due to indent changes)
10:57<Alberth>speed is not really the problem, more switching from assembly to C to C++. Lots of legacy code to convert to the new conventions
10:59<Alberth>Rubidium: I understand. Just the sheer number of patches would makes it an endless process already.
11:00<CIA-3>OpenTTD: rubidium * r13046 /trunk/src/ (group_gui.cpp vehicle_gui.cpp vehicle_gui.h): -Codechange: make classes of the VehicleListWindow and the VehicleGroupWindow.
11:08<CIA-3>OpenTTD: glx * r13047 /trunk/src/ (10 files): -Codechange: remove vp_d
11:09<Alberth>Nice thing about the deeper stuff is that you get a good idea of how the program really works. Yesterday I found out that new windows are always opened near the oldest window. I changed it to first try the newest window.
11:10<Alberth>Such changes are probably noticed by the users too, except they won't know what is different.
11:10<Alberth>glx: We now have a Viewport widget? :P
11:11<+glx>not really
11:11<planetmaker>sure. The best way to learn a programme is to hack it :)

13:45<cjk>race who makes the most classes out of code?
13:46<cjk>Rubidium: we need descriptions for servers. currently people cram everything into the title...
13:47<Rubidium>and that won't stop when you add descriptions
13:48<Rubidium>because with descriptions you have to scroll server-by-server through the list to get information instead of getting it directly when scrolling through the list
13:48<Rubidium>furthermore there's no space in the network protocol to do that
13:50-!-Xeryus|bnc is now known as XeryusTC
13:53<Smoovious>well, the descriptions would help to have running conditions in long-hand, url's, etc... can still keep the abbreviations in the title

13:58<Eddi|zuHause3>if there's no space for it in the masterserver communication, "get description" could be a direct client<->server communication upon user clicking a button
13:59<cjk>or that
13:59<Smoovious>Eddi|zuHause3 sounds good
13:59<cjk>basically what I want is like.. showing when autoreset is taking place
13:59<cjk>just some descriptional space where I can mention the source code changes

15:21<Chicago_Rail_Authority>Ignorant Question: Are NewCargo categories defined in a universal way that would allow for more advanced filters on the vehicle purchase windows? Now that we can have massive amounts of sets loaded, it is more difficult to find/compare different wagons for various cargos, etc. It would be nice to have a cargo filter to more quickly/easily find all wagons that can carry ____.

15:44<Chicago_Rail_Authority>Not sure how it addresses Rubidium's concerns, though.
15:45<Ammller>it does at least support ECS, no idea how it work deeper...

17:19<Sacro>how can you get from X = Y/ Sqrt(X^2+Y^2+Z^2)
17:19<Sacro>to X = Y / 1
17:21<planetmaker>Sacro: for a sphere x^2+y^2+z^2 = 1 on surface
17:22<planetmaker>*unity sphere
17:24<Rubidium>so X = Y and X = Y / sqrt(...)?
17:25<planetmaker>yeah. and z=0
17:25<Rubidium>=> X = Y and 1 = X^2+Y^2+Z^2
17:25<Eddi|zuHause3>where do you read z=0 from?
17:26<planetmaker>from my tiredness. :P
17:26<Rubidium>=> 1 = 2 * X^2 + Z^2
17:26<Rubidium>=> 2 * X^2 = 1 - Z^2
17:26<Rubidium>=> X^2 = (1 - Z^2)
17:27<Eddi|zuHause3>missing /2
17:27<Rubidium>=> X = sqrt((1 - Z^2)/2)
17:28<cjk>could not you just have used a CAS for that
17:28<Rubidium>that'd be lame ;)
17:28<cjk>also, your Y just disappeared
17:28<Rubidium>did not
17:28<cjk>Out[2]//InputForm= {{x -> -Sqrt[1 - y^2 - z^2]}, {x -> Sqrt[1 - y^2 - z^2]}}
17:28<Rubidium>X = Y, so I can substitute X for Y
17:28<planetmaker>cjk: CAS are only as intelligent as the questions asked. Y was not forgotten

17:35<Rubidium>no, x=y

17:52<Rubidium>cjk: yeah right...
17:54<Rubidium>a = b * c, when a = b, then c must be 1. when b = c, then a = b^2 and a = c^2. Under the former c can only be 1, under the latter c can be anything. But... according to you the result would be the same in both cases
