solVItaire

Play klondike and spider solitaire in your unicode terminal.

Supports vi style keybindings (hjkl), cursor keys and the mouse. Press J to 'join' a well-suited pile to the cursor. Space locks in a selection, and Return pulls cards from the stack in spider solitaire. Piles can also be directly addressed by the number below them (or 8, 9, 0 for stack, waste and foundation in klondike).
See $PROGNAME -h for details.

Makefile Options

By default the character set uses an X to for the 10 card. Compile with make DECIMAL_TEN=1 to display the letters 10 instead.

TODO

P1

TODO FREECELL: autodetect possible moves (card selector choice dialog)

P2

TODO: klondike/freecell: auto-move to foundation (optional)
TODO: suggest moves (h => hint)
TODO: cleanup: in x2y() functions there is a lot of replication and noise when calculating legal moves, top cards, etc.

P3

TODO: visbell changes: instead of screen, flash active {cursor,card} {red,twice}?
TODO: differential drawing mode (at least for highlighting cards)
TODO: . command (repeat last action)

P4

TODO: ellipsis overlap: if more than three cards in a row overlap, replace middle ones with an ellipsis
TODO: mouse mode improvements: - spider/freecell: detect how many cards to move to empty pile (must find exact position despite extreme_overlap)
TODO: scores, variants: draw 3, max. n overturns
TODO: vt220 mode (problems: charset, slow baudrate and no differential drawing mode)
TODO: ed(1) mode (solEDaire): playable on a line printer; ascii/ibm only?

DONE

DONE: use #ifdefs to differentiate games (sol, spider, ed-sol, ed-spider)
DONE: keyboard alias: twice same key == waste/pile -> foundation
DONE: spider keyboard: <from><to> stacks; 1-9,0=tableu, return=draw
DONE: spider: easy/medium difficulty: only deal 1/2 suits instead of 4 -> deal()
DONE: patience: allow taking from 0(foundation)
DONE: highlight from pile, so users can see at what input stage they are
DONE: make piles 0-indexed in klondike as well
DONE: duplicate card ♠A found in tableu: added check at start to monitor this Cannot reproduce, removed check
DONE: bugs in spider's t2t() * once segfaulted on large column * sometimes doesn't work (ERR when it should be OK) Cannot reproduce
DONE: some input functions are in x2y() -- move them to get_cmd() (req. for mouse, hjkl modes)
DONE: sigint, sigcont handler! atexit() to avoid inconsistent term state
DONE: hjkl keyboard mode
DONE: more vim mode keys (first/last tableu)
DONE: online (key-)help ?, -h, -v (NOTE: implemented -h, rest deemed not usedul)
DONE: extreme overlapping: if we are printing a sequence or multiple face down cards, only print .overlap lines of the ends, and 1 line for the middle cards
DONE: in direct addressing 'up to' dialog: make return/space select the lowest/highest option
DONE: undo:
- insert append_undo() in x2y() functions
- to encode stack position we need to overload f.u.n as index. (similar for foundation: overload f.u.n as foundation id)
- w2f(): have to encode both stock index and foundation id don't want to add a struct field for this one case; for the time being (i.e. forever) I'm ORing waste index and (foundation id<<16). ugly but works :/
- turning over cards: this needs to be encoded, because the card might be consecutive and there's no way to tell what its previous state was.
  - indicate that a card was turned (can be at most 1) by negating u.n pros: no wasted space (it's just a boolean value), negation pattern already used for closed cards cons: dirty C hack, less obvious than in other places, no need to conserve memory this tightly
DONE: screen size > stack height => rendering issues! as good as it's going to get, since we can't just not draw cards at all
DONE: 'join to here' command (should take longest chain available)
DONE: expose deal() seed for restarting the game
DONE: make portable (clang on FreeBSD) makefile's $< refuses to work if prequisite name != target name Fix: ln -s sol.c. spider.c sed -i 's/^spider: sol.c/spider: spider.c/' Makefile
DONE: escape sequences (for real cursor keys)
DONE: inverted moves (if A->B doesn't work, try B->A)
DONE: - allow dragging the mouse
DONE: use 10 instead of X on card face (/u/Valley6660)
DONE: :help to show keyhelp (/u/Valley6660)
DONE: don't show cursor-highlight when inputting directly or with the mouse (/u/TooEarlyForMe)
DONE: remove sysmlink trickery and just call sol.c explicitly
DONE FREECELL: t2t() multi card move and accompanying pop_undo()
DONE: - mouse (term2pile() cell encoding, set_mouse(), wait_mouse_up())
DONE FREECELL: don't allow selecting more cards than movable (DO_HI, TOP_HI, cursor_{up,down})
DONE: differentiate foundation placeholder from cells ph. (freecell)
DONE FREECELL: join()
