Implementation Feasibility - -### A. Stateless Lexing (High Feasibility) -The core lexing logic (`module.lexer.ts`) is already highly modular. Functions like `parseWeekday`, `parseDate`, and `parseTime` are pure or near-pure. They could easily be adapted to take an explicit `options` object instead of relying on an instance config. - -### B. Refactoring the Engine (Medium Feasibility) -To make `ParseEngine.parse` standalone, we would need to: -1. **Lift State**: Instead of using `this[sym.$Internal]()`, the engine would accept a `State` object as an argument (or initialize a transient one). -2. **Parameterize Config**: Pass `timezone`, `locale`, and `formats` as an explicit options object. -3. **Functional Composition**: The logic in `module.composer.ts` (which assembles the final date) is already functional and would require minimal changes. - -### C. Challenges & Trade-offs -1. **Circular Dependencies**: If the standalone `parse` function were to return a `Tempo` instance (convenience wrapper), it would create a circular dependency with `tempo.class.ts`. To avoid this, it should strictly return `Temporal.ZonedDateTime`. -2. **Global Defaults**: A standalone function wouldn't automatically respect `Tempo.init()` defaults unless it explicitly looked them up from the global registry (e.g. `REGISTRY.defaults`). -3. **Validation (The Guard)**: The standalone function MUST include the `Guard` validation logic to ensure that inputs are sanitized and valid before attempting lexing. -4. **Forced Strict Mode**: For standalone parsing, it is recommended to force `mode: 'strict'`. This prevents the parser from "guessing" or returning partial dates when the input is ambiguous, ensuring deterministic results for native Temporal users. - -## 4.

Conclusion -Implementing a standalone `parse` function is **Highly Feasible**. -- Refactoring the `ParseEngine` to be stateless (accepting config/state as arguments) is the first step toward decoupling the parser. -- A wrapper `parse()` function will then be exported from `#tempo/parse` to provide a dedicated standalone entry point. -- Finally, `Tempo.class` will be updated to delegate its internal `#parse` logic to this shared stateless engine. - -This would allow Tempo to serve as a high-performance "Natural Language to Temporal" parser for users who prefer the native Temporal API but want the "Slick" parsing capabilities of Tempo. diff --git a/packages/tempo/src/discrete/discrete.parse.ts b/packages/tempo/src/discrete/discrete.parse.ts index f8cd7260..7bfa45c8 100644 --- a/packages/tempo/src/discrete/discrete.parse.ts +++ b/packages/tempo/src/discrete/discrete.parse.ts @@ -18,6 +18,8 @@ import type { Range, ResolvedRange } from '../plugin/plugin.type.js'; import type { Tempo } from '../tempo.class.js'; import * as t from '../tempo.type.js'; +const isZDT = (obj: any) => obj && (obj[Symbol.toStringTag] === 'Temporal.ZonedDateTime' || typeof obj.toInstant === 'function'); + /** @@ -62,8 +64,8 @@ const _ParseEngine = { const basis = isDefined(val) ? val : instant().toZonedDateTimeISO(config.timeZone); const [tz, cal] = isTempo(basis) ?

Here are my thoughts on how we should handle this to maintain Tempo's flexibility while ensuring predictability: + +### 1. Conflict Philosophy: "Explicit Shadowing" +Tempo's strength is its "config-merging" capability. We should embrace a **"Last One Wins" (Shadowing)** strategy. +- **Reasoning**: This mirrors how CSS or JS modules work. If a user explicitly provides a configuration in `Tempo.init()`, they are stating their intent to use *that* definition for their application context. +- **Hierarchical Priority**: `Local (Instance) > Factory (init) > Plugin > Global Default`. + +### 2. Conflict Detection & Feedback +While "Last One Wins" should be the resolution, the user should be informed if they are accidentally clobbering a built-in alias. +- **Warning Level**: If an alias key (or pattern) matches an existing one, issue a `console.warn` (when `debug: true`). +- **Heuristic Improvement**: Our current `#isAliasCollision` is a good start. We could improve it by checking for "Pattern Saturation"โ€”if a new regex pattern is a subset of an existing one, or vice versa. + +### 3. The "Sandbox" Factory Pattern +I strongly support the idea of `Tempo.init()` returning a **New Tempo Class**. +- **The Pattern**: + ```typescript + const AppTempo = Tempo.init({ period: { 'half-hour': ... } }); + const t = new AppTempo('half-hour'); // Uses AppTempo's registry + ``` +- **Benefits**: This prevents "Global Pollution". Multiple micro-services or components within the same process could have different Tempo configurations without stepping on each other's toes. +- **Implementation**: We could use a `class factory` that extends the base `Tempo` and overrides the static `#global` state for that specific lineage. + +### 4. Traceability & Debugging +The suggestion to record collisions in a `#parse.result` array is excellent. +- **Discovery Trace**: We should include a `meta` property in the result that indicates which registry entry was used (e.g., `source: "local"`, `source: "plugin:astro"`, `source: "default"`). +- **Collision List**: If a clash occurred but was resolved by shadowing, we should keep a list of the "shadowed" candidates in the instance state to assist developers when they wonder why "noon" isn't behaving as expected. + +### 5. Recommendation +- **Default to Overrides**: Don't throw errors for clashes; it breaks the "nice API" goal. +- **Formalize the Factory**: Move towards the `Tempo.init() -> Class` pattern as the primary way to configure Tempo for an application. +- **Enhance Warnings**: Make the collision warnings more descriptive, showing exactly what was overridden and by whom. + +## 2026-04-24: Sandbox Factory Pattern (Consolidated) + +The Sandbox Factory pattern has been finalized to ensure fully isolated, reproducible Tempo configurations without global state pollution. + +### Key Decisions: +1. **API Naming**: We introduced `Tempo.create(options)` as the primary entry point for creating isolated sandboxes. This separates the concern of "forking the library" from `Tempo.init()`, which remains the tool for managing the global singleton or resetting context. +2. **Inheritance vs. Cloning**: Sandboxes now perform a shallow clone of the parent registries (`event`, `period`, etc.) upon initialization. This prevents the "Registry Leak" issue where adding an alias to a sandbox would inadvertently update the parent. +3. **Local Scope Enforcement**: To simplify alias resolution and ensure traceability, sandboxed class states are tagged with `scope: 'local'`. This causes sandboxed aliases to be recorded with a `source: 'local'` tag in parse results, distinguishing them from the base library's global defaults. +4. **Prototype Chain Resolution**: The `ParseEngine` has been hardened to support recursive `ownEntries` lookups. This allows instances to inherit from their sandbox class, which in turn can inherit (selectively) from the base `Tempo` class, providing a robust polymorphic configuration chain. +5. **Secure Discovery**: Each sandbox is registered in `globalThis` via a unique discovery symbol (or string), allowing the `ParseEngine` to correctly resolve custom periods and events even when called from within complex, nested class contexts. + +### Status: +Fully implemented and verified in `sandbox-factory.test.ts`. 100% pass rate achieved. diff --git a/packages/tempo/src/discrete/discrete.parse.ts b/packages/tempo/src/discrete/discrete.parse.ts index ea623a2d..cd8b0815 100644 --- a/packages/tempo/src/discrete/discrete.parse.ts +++ b/packages/tempo/src/discrete/discrete.parse.ts @@ -360,7 +360,7 @@ const _ParseEngine = { const isEvent = Match.event.test(key); const isGlobal = key.startsWith('g'); const isNamed = key === 'gdt' || key === 'dt' || key === 'gtm' || key === 'tm'; - const idx = isNamed ? -1 : +key.substring(4); + const idx = isNamed ? -1 : +(key.match(/\d+$/)?.[0] ?? -1); if (isNamed) { resolved.add(key); @@ -380,6 +380,12 @@ const _ParseEngine = { continue; } + if (!entry) { + resolved.add(key); + delete groups[key]; + continue; + } + const aliasKey = entry[0] as string; if (resolvingKeys.size > 50 || resolvingKeys.has(aliasKey)) { const msg = `Infinite recursion detected in Tempo resolution for: ${aliasKey}`; @@ -452,7 +458,8 @@ const _ParseEngine = { const type = isEvent ?
