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.inventory

A pack: a count per kind of item. The game names the kinds and says how many of each fit; the package keeps the counts, refuses what does not fit, and reports every change. Uses ludic.base and nothing else.

import "ludic.inventory"

A kind is the game's number for an item (its place in the game's item table). The game hands the package each kind's NAME with inv_config(keys), and the save is by name - {"counts": {"wood": 3}} - so a game can add, remove or reorder its items without a migration; a name the build no longer knows is dropped on load.

The port

export port PackRules {
  stack_limit: fn(int) -> int = ...   # how many of a kind fit (unbound: no limit)
}

The game fills it once, where it is put together: bind PackRules { stack_limit: fn gear_stack }.

API


`bind PackRules { ... }`, `inv_config(keys)`	the port (a declaration), and the kinds by name (the pack starts empty)
`inv_add(it, n) -> int`	as many of `n` as there is room for; returns how many went in
`inv_take(it, n) -> bool`	all `n` or none
`inv_set(it, n)`	a count outright, room or not (a starting kit, a correction, the network's word); never below 0
`inv_clear()`	everything gone, silently
`inv_count(it)`, `inv_has(it, n)`, `inv_room(it)`, `inv_limit(it)`, `inv_total()`, `inv_kinds()`	what the game asks; a kind out of range counts 0 and has no room
`inv_changes() -> Queue<ItemChanged>`	the facts: `{ item, before, after }`, one per change, none for a no-op or a load
`inv_system() -> System`	`"inventory"`, `PH_COMMIT`: reset, and its save section (`inv_save`, `inv_load`)
