5304 :: Nim Coding Examples and Exercises for beginners?

• torarinvik (orginal) [2019-10-08T16:46:14+02:00] view original

  Hi I need some help with tips to write some beginner level programs in Nim. I wonder if you have examples of some simple projects I can do to improve my coding skills? I am very interested in things like Tic Tac Toe game, Snake game or any kind of cool, interesting or rewarding projects that is not too hard. BTW I really like the Brainfuck interpreter project in the learn section.

  Thank you for any answers. Any advice is welcome :)

  For Tic Tac Toe (and maybe some other interesting small projects): take a look at "Nim Days" https://xmonader.github.io/nimdays/

  I tried that game but it gives me error. It says newGame is not declared. I don't see any myself. I did "import ui" on top of project.

  proc gui*() =

  var mainwin = newWindow("tictactoe", 400, 500, true)

  game object to contain the state, the players, the difficulty,...

  var g = newGame(aiPlayer="O", difficulty=9)

  var currentMove = -1 mainwin.margined = true mainwin.onClosing = (proc (): bool = return true)

  set up the boxes

  let box = newVerticalBox(true) let hbox0 = newHorizontalBox(true) let hbox1 = newHorizontalBox(true) let hbox2 = newHorizontalBox(true) let hbox3 = newHorizontalBox(true) # list of buttons var buttons = newSeqButton

  information label

  var labelInfo = newLabel("Info: Player X turn") hbox0.add(labelInfo)

  restart button

  hbox0.add(newButton("Restart", proc() =

  g =newGame(aiPlayer="O", difficulty=9)

  for i, b in buttons.pairs:

  b.text = $i b.enable()))

  Funny, I did a chess game too some years ago.

  The chess game looks awesome. Impressive stuff for such a small amount of code. Is it just me or do Nim create really compact code? I would imagine C++ with the libraries might require more.

  When that is said, the chess game is a little too advanced for me at this moment. But I might try it a little bit later when my coding skills have grown. Certaintly a cool project to do.

  Have a look at the Nim track of exercism.io

  @narimiran, maybe this should be in the learn page as well.

  Wow, thanks was exactly what I was looking for. The only thing I need now is some tutorials on GUI creation in Nim.

  Can you provide any example how to use a modern database (Sqlite3/Mysql/Postgres) with Nim on Windows? I've tried to use Postgres, but libpg was not detected properly.
