klon

klon is a text-mode Klondike (aka Solitaire) card game implementation.

Why? Because everything's better in text mode.

Each playable card has an address:

• The waste, the last face-up card drawn from the deck, is W.
• The four foundation piles in the top-right, where you are trying to move your cards to, are 0A thru 0D.
• The tableau, the main piles of cards in the bottom half of the screen, are numbered by column, 1 thru 7, and each position is lettered. When the game begins, these are 1A thru 7G.

To move a card, enter a source followed by a destination.

• To move an entire stack of cards, or a part of a stack, name the card at top of the stack you want to move. The ones stacked below it will move with it.
• To move to the bottom of a tableau column, just enter the column number, without any row letter.
• As a shortcut, to move a card to the foundation, because it can only go in one place, you can omit the destination and the game will do the correct thing.

To flip over a card that is face-down, just enter that card's address, without any destination.

To draw three cards from the deck into the waste, enter DD. When the deck has been exhausted, this will recycle all the waste cards back into the deck in the same order, to be dealt again.

If you want to take back a move, type undo.

When you start klon without any command-line arguments, it randomizes the deck, but it gives you a "game number" that can be used to generate that same deck again. Run klon with that number as an argument to play it again.

klon keeps a record of the moves you've made. You can write it to a file by typing log <filename>. You can load that file and replay the moves in it by typing load <filename>. The first line of the log file says what game number it is for.
