cg-shuffle gains an optional SEED and a `cg-shuffle-seed' dynamic var.
With a seed the order is deterministic and identical on every platform,
so a deal can be replayed, shared between players, or pinned in a test;
the index comes from secure-hash (spec-defined output everywhere, 7 hex
digits stay a fixnum even on 32-bit Emacs), so no bignum/overflow
behaviour can vary it. With no seed the shuffle is the byte-for-byte
old system-random path -- normal play is unchanged.
Test cgt-shuffle-seeded pins determinism, permutation, override and a
cross-platform golden prefix; fails on the prior one-arg cg-shuffle.
Suite 159/159.
Bump z per the releasable-set convention. Ship the Info manual
(make info; make info-emacs fallback). Generate README.md from
README.org via Emacs batch ox-md, with a pre-commit hook and
board screenshots.
* card-games.el (card-games-treatment, card-games--svg-card-vars,
card-games--full-svg-vars, card-games-set-treatment): switch all games
between UNICODE, SVG cards, and the full-window SVG table by toggling the
per-game display vars together. (card-game--cycle-treatment, card-game):
a clickable control in the chooser.
* test/card-games-tests.el: cgt-treatment-set.
* NEWS: note the treatment selector.
* cg-core.el (cg-ai-level): new difficulty defcustom. (cg-red-suit-p):
return a normalised boolean so two red suits compare equal by colour --
diamond and heart were wrongly treated as opposite colours, letting a red
card build on another red card in the alternating-colour games.
* cg-crapette.el (cg-crap--ai-greedy-move, cg-crap--ai-play): honour easy
/ normal / hard.
* cg-trick.el (cg-trick--run): easy plays a random legal card.
* card-games.el (card-game): clickable AI-level control.
(card-game--cycle-ai, card-games-set-ai-level): change it.
* test/card-games-tests.el: cgt-red-suit-boolean, cgt-ai-level-easy-crapette;
bind cg-ai-level in cgt-crap-ai-enabling.
* NEWS.
* cg-svg.el (cg-svg-card-back): default to random; add lattice/waves/diamond
and the emacs/emacs-classic/gnu/splash logo backs. (cg-svg--back-*,
cg-svg--draw-back): draw them. (cg-svg--card-backs, cg-svg--random-back,
cg-svg--roll-back, cg-svg-shuffle-card-back, cg-svg--effective-back): random
machinery.
* card-games.el (card-game): re-roll the random back on each menu visit.
* test/card-games-tests.el: add cgt-svg-logo-smoke, cgt-svg-card-back-smoke.
* NEWS: note the card backs and random default.
* cg-crapette.el: new game on cg-core — eight foundations (up by suit,
two decks), eight shared houses (down, alternating colour), per-player
reserve/waste/hand; foundation priority; loading onto the opponent; a
greedy AI; text UI with cursor pick/drop, undo, and q-to-menu.
* card-games.el: require cg-crapette and add the chooser entry.
* Makefile (EL): add cg-crapette.el.
* test/card-games-tests.el: 5 ERT (deal, legality, win, AI turn, AI foundation).
Full-SVG 500 made mouse-operable for newcomers: kitty Discard button and
five-card cap, on-table phase banner, ? Help/Rules overlay with the bid
legend, legal-play dimming, card-size slider, and a layout pass that
moves the Help and size controls into the log panel so nothing overlaps.
Bump all files to 1.0.90, add NEWS, a README testing quick-start, and
make the shared engine files checkdoc-clean.
New cg-bridge.el: a four-handed Bridge game (you are South, partnering
North against East and West) on the shared cg-game base.
* Auction: level/strain bids plus pass, double, and redouble, with the
three-pass end rule, pass-outs, doubling state, and declarer
determination (first of the side to name the strain).
* Play: follow-suit with the dummy exposed after the opening lead; the
declarer plays both hands. Trick resolution honours trump and no-trump.
* Scoring: classic rubber -- trick points below the line toward game;
overtricks, slam, insult, and undertrick penalties above; vulnerability
and the rubber bonus. Verified against known results.
* A small natural bidding AI (openings, NT, raises with a fit, simple
overcalls) that always terminates the auction, plus a greedy
card-play AI.
Wire cg-bridge into the chooser, the Makefile, and the README, and add
two ERT tests (scoring math and a dozen full AI-driven deals). The suite
is now 109/109 and every file byte-compiles cleanly.
Euchre, Pitch, Briscola, and Spite & Malice
Five new files, each reusing or extending an existing engine.
* cg-match.el: Go Fish and Old Maid, matching games on a shared
helper set (completes the original wishlist).
* cg-cribbage.el: two-handed Cribbage to 121 -- the crib, the cut,
pegging, and a full show scorer (fifteens, pairs, runs, flush, nobs).
* cg-scopa.el: a capture-by-sum engine driving Scopa (40-card, sette
bello, primiera, scopas) and Casino (pairs and sums, big/little
casino, aces, sweeps). Casino omits builds.
* cg-trick-ext.el: Euchre (24-card with both bowers), Auction Pitch
(bid, pitch sets trump, High/Low/Jack/Game), and Briscola (fixed
trump, no follow), as subclasses of the cg-trick engine.
* cg-spite.el: Spite & Malice, a competitive patience to empty the
goal pile onto shared Ace-to-Queen centre piles; Kings are wild.
Wire all nine commands into the card-game chooser, extend the Makefile
EL list, and add README sections. Add ten ERT tests covering each
game's engine and a full AI-driven game; the suite is now 107/107 and
every file byte-compiles cleanly.
New files at Version 1.0.60 to match the tree; post-1.0.60 work
toward 1.0.90.
Introduce a shared meld engine and four games built on it, all on
cg-core/EIEIO with console UNICODE rendering.
* cg-rummy.el: the meld engine and Gin Rummy. Set/run validation,
candidate-meld enumeration, a bitmask-DP minimum-deadwood partition,
and a layoff finder, plus the abstract cg-rummy-game base and shared
render helpers. Gin is two-handed with draw/take/discard/knock, gin
and undercut bonuses, opponent layoffs, and play to 100.
* cg-rum500.el: the abstract cg-tablemeld-game (one mode and command
set, dispatching on the subclass) driving Basic Rummy (meld out;
score the cards left in other hands; to 100) and Rummy 500 (score the
cards you lay down, lose those left in hand; ace high and worth 15;
to 500).
* cg-handfoot.el: Hand & Foot, a partnership Canasta cousin. Hand and
foot packets, Twos and Jokers wild, rank books with clean/dirty piles,
go-out bonus, and partnership scoring to 5000. Deliberately
Host-authoritative networked 500: host sits South, joiners take W/N/E,
open seats filled by AI. Per-seat rotated state hides other hands and the
kitty; clients reuse the single-player renderer/commands via :around advice,
so cg-bid.el/cg-bid-ui.el are untouched. Adds cg-bid-host/cg-bid-join, a
start-now lobby with auto-start at four players, and cg-bid-shuffle-partners.
cg-net.el gains cg-net-connect-functions. Verified: clean byte-compile,
checkdoc, 34/34 ERT (incl. 3 new net tests) and a two-process TCP game.
