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.
* 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-trick.el (cg-trick--svg, cg-trick--draw-backs): draw the whole table
as one SVG -- three opponents, the trick in a diamond, the South hand
fanned with cursor, legal-play hints, and pass marks; hand cards carry
(hand . INDEX) click regions. (cg-trick--render-text): the text fallback.
(cg-render): dispatch SVG on a graphical display, else text. Add a footer
legend; refresh the help. Covers Hearts, Spades, Whist, Oh Hell, and the
Euchre/Pitch/Briscola subclasses.
* test/card-games-tests.el: add cgt-trick-svg-smoke, cgt-trick-svg-bidding.
* NEWS: note the trick-taking SVG table.
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.
Shared hand row gains a region-tag: tagged hands carry a cg-regions click
map (cards -> (hand . i)) and a card-size slider in the same image.
cg-core adds cg-mouse-action, cg-card-click, zoom commands, cg-card-scale
(folded into cg-scale), and a cg-render-apply base for scale/zoom. Seven
hand games are now click-to-position (Scopa/Casino/Spite click-to-play),
with [mouse-1] and +/-/0 bound. Adds cgt-hand-regions; suite 111/111.
cg-renderer gains a regions slot; the text/svg treatments get real
draw/hit methods; cg-regions-hit + cg-render-apply complete the loop.
Prototype on solitaire: cg-sol--svg returns (image . regions), redisplay
goes through cg-render-game, and [mouse-1] selects-and-acts by reusing the
keyboard pick-up/drop. Adds cgt-keystone-regions; suite 110/110.
