code here: http://arsdnet.net/dcode/minesweeper.d Here's a bit of fun. I saw this article on reddit: http://rkoutnik.com/articles/How-I-Interview.html Short summary: when interviewing people for a code position, this author gives the candidate one hour to write as much as minesweeper as they can. He says nobody has ever finished it in an hour and nobody is expected to, but he just wants to see how far they get. Nobody has finished it in an hour? CHALLENGE ACCEPTED. I decided to give it a go over the last hour and hacked this together: http://arsdnet.net/dcode/minesweeper.d It depends on my simpledisplay.d and color.d from here: https://github.com/adamdruppe/arsd Download just those two files, simpledisplay.d and color.d, to your current directory with minesweeper.d and compile: dmd minesweeper.d simpledisplay.d color.d And play the game! At least on Windows and Linux. On Mac, you need to install XQuartz since I don't have a working Cocoa implementation in simpledisplay.d right now. Fear not, it is on my todo list for 2016, so it will be there eventually. My game isn't exactly fancy.... but it is playable. here's a screenshot: http://arsdnet.net/minesweeper.png I prolly could have used a downloaded icon set and made it look prettier, but I didn't want to look for one nor deal with copyright so I just drew text and rectangles. Now, the interviewer used javascript, but I wanted another example for simpledisplay.d, so I used that instead. In JS, given the time constraint, I think I would have done it as an array of <img> tags with an onclick handler on the parent node which changes the src to a particular icon, or a class name for a css sprite. whatever. But the JS algorithm would be basically the same and I suspect I could do it in a similar amount of time since it is a simple program anyway. I just like D better. I had to look up the flood fill which took seconds (I played real minesweeper and recognized it was the same algorithm MS Paint uses. I started to hack it myself but realized that I didn't really know it that well and figuring it out myself from principles, while doable, would likely eat my remaining time right there, so I Binged "paint fill algorithm". Wikipedia popped right up with a description was good enough to run with: https://en.wikipedia.org/wiki/Flood_fill I implemented the simple recursive version as a template with a few parameters to fit my needs here, while also being usable in my other side project, which has a MS Paint like graphics editor and needs this feature anyway! Anyway, he rest was pretty straightforward. The complete game has a timer, a scoreboard, a UI for selecting size, etc. I have functions that could do that, but didn't have time to actually put on more UI than the basic game with mouse clicks.... ...so indeed, I didn't finish it either. Challenge failed :( But since it is playable i'm calling this a pretty decent success anyway! And now I have one more example to show off with simpledisplay.d, which I will might add to the documentation http://arsdnet.net/arsd/simpledisplay.html along with the existing Pong game. I didn't use any really special D features there, so not really a language showcase - like I said before, if I was doing it in Javascript, I probably would have done it largely the same - but hey, it is D, so I will post it here :)

Pick any 80's arcade game and try to implement as much as possible in an hour. I have several languages I cycle through but the last 1-hour gamehack in D I did is here: "D-Invaders" under: http://dgame-dev.de/index.php?controller=wip The Github repo now has a bunch of extra commits since that initial hour to keep it compiling with Dgame and D. It isn't pretty, nor idiomatic, but I was learning D and Dgame at the same time in that hour :) I realised two things from that first hour with D, which have both proved true so far: a) (the most important for me) I can be as productive in D as I am in Python but still keep my static typing and native performance I get with C/C++. b) D is only going to keep improving. Cheers, Stew

Dgame looks to be a pretty nice little lib too.a) (the most important for me) I can be as productive in D as I am in Python but still keep my static typing and native performance I get with C/C++.My D productivity is so much higher than I am with ruby and python it isn't even a competition...

But what I posted here is the most of what I'd say anyway. I guess I could write a bit more about the code but most of it is IMO at least fairly straightforward.

Everywhere else I tried on Linux it just worked but it does indeed require GL and GLU just because simpledisplay on Linux links to them, though I didn't actually use OpenGL for this program. (on Windows, opengl support is opt-in because the opengl32.lib and glu32.lib aren't included with dmd, I could do that on Linux too I suppose but installing glu isn't that hard anyway...)

Not really solving the problem though... Nice work though! 'Tis very cool. The game code is very simple to follow too. I'll try making a simple game using simpledisplay over the christmas. It looks quite nifty!
