Standard deck of 52 playing cards in curated data?


I am not sure how to find out what all is included as curated data. For example, are the individual images of each of the 52 cards in a standard deck of playing cards included?



If not, is there a way to systematically access these from web images?



Answer



You can get some nice vector playing cards from this site, licensed under GNU LGPL (read more here). Download this folder to your computer and then try the following:


(* replace with your download dir *)
files = Flatten@With[{dir = "~/Downloads/Chrome/mma/SVG_and_EPS_Vector_Playing_Cards_Version_1.3/EPS_Vector_Playing_Cards_Version_1.3/52-Individual-Vector-Playing-Cards-1.2_(EPS-Format)/"},
FileNames["*.eps", dir, 2]];

Clear@CardData
SetAttributes[CardData, Listable]
StringCases[Last@FileNameSplit@#, card__ ~~ ".eps" :>

(CardData[card] = ImageCrop@Import@#)] & /@ files;

You can then use this like any other curated data:


GraphicsRow[CardData@{"2C", "KH", "AS", "QD", "JC"}]




Random hand generator:


You can extend this further and also create a random hand generator using Mathematica as follows:


deck = Flatten@With[

{
ranks = CharacterRange["2", "9"] ~Join~ {"10", "J", "Q", "K", "A"},
suits = {"C", "S", "H", "D"}
},
Outer[StringJoin, ranks, suits]
];
dealHand[n_Integer] /; 1 ≤ n ≤ 52 := CardData@RandomSample[deck, n]

Use this to deal a hand as dealHand[5], for instance. You'll have to modify this a bit to deal randomly and exhaust the deck at the same time (as you would in a game). There was a question on this previously on this site and I gave an answer based on Internal`Bag[] that will be useful here (along with some of the other answers there).

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...

plotting - How to draw lines between specified dots on ListPlot?

I would like to create a plot where I have unconnected dots and some connected. So far, I have figured out how to draw the dots. My code is the following: ListPlot[{{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4,13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full] I have thought using ListLinePlot command, but I don't know how to specify to the command to draw only selected lines between the dots. Do have any suggestions/hints on how to do that? Thank you. Answer One possibility would be to use Epilog with Line : ListPlot[ {{1, 1}, {2, 2}, {3, 3}, {4, 4}, {1, 4}, {2, 5}, {3, 6}, {4, 7}, {1, 7}, {2, 8}, {3, 9}, {4, 10}, {1, 10}, {2, 11}, {3, 12}, {4, 13}, {2.5, 7}}, Ticks -> {{1, 2, 3, 4}, None}, AxesStyle -> Thin, TicksStyle -> Directive[Black, Bold, 12], Mesh -> Full, Epilog -> { Line[ ...
