Orkuncakilkaya 71735b10a2 feat(base): 0.R4 - a queue keeps its own count, so every package verb takes only its own state; ludic migrate state --prune
ludic.base's Queue<T> carries a QueueTag (its name and pending count): queue_new(name), q_push(q, v),
q_drain(q), q_clear(q) take no BaseState, and core_undrained(tags) names the given queues still holding
facts. A reducer on a package's state can now call that package's verbs (wallet_earn(wallet_st, n)).

ludic migrate state --prune (ludicc --migrate-prune) takes out each state parameter a function no
longer uses, nor anything it calls, and the argument that fills it - including an argument for a
parameter the callee has dropped, which is taken out before the call is checked, so a generic's T is
told by the argument that says it. A reducer keeps its state. --dry-run now counts the edits it would
make. Every package was moved with it: 608 base_st parameters and their arguments, 1889 edits.

ludic.wallet

Money carried, in whole units: earned, spent only when it is there, lost when a cost happens anyway, and every change reported. Uses ludic.base and nothing else. Prices, reputation and what a thing costs are the game's; the wallet only holds the money.

import "ludic.wallet"

No ports: the wallet asks the world nothing.

API

wallet_money(), wallet_can(n) what is there, and whether n is
wallet_earn(n) add
wallet_spend(n) -> bool only what is there: false, and nothing spent, when it is not
wallet_lose(n) a cost that happens whether or not it can be paid (a rescue); never below zero
wallet_set(n) exactly n (a starting purse, a correction, the network's word)
wallet_changes() -> Queue<MoneyChanged> the facts: { before, after }, one per change
wallet_system() -> System "wallet", PH_COMMIT: reset, and its save section (wallet_save, wallet_load)

Tests

ludic build packages/ludic.wallet/tests/wallet_test.ludic --headless -o /tmp/wallet_test && /tmp/wallet_test
