Cron parsing and validation produces correct CronExpression ASTs from standard 5-field inputs, supporting aliases and extensions like L, W, and # with Vixie semantics. It enforces 5-field cron syntax and normalizes 7 to provide a verified TypeScript reference.
Calculating next and previous cron occurrences is handled by a single CronSchedule facade. This scheduling API exposes next, prev, nextN, and iterate functions, enabling end-to-end matching and iteration across varied scheduling use cases.
Yes, cross-language translation is supported by providing language-agnostic specs and references. Types and interfaces come with translation hints to speed up porting the verified TypeScript reference to Python, Rust, Go, or TypeScript.
Yes, the cron parser enforces 5-field syntax with Vixie semantics. It supports standard aliases and modifiers, including L for last day of month, W for nearest weekday, and # for nth weekday of the month.
Generating a native cron scheduler involves using the verified TypeScript reference to produce parsing, matching, and scheduling implementations. This eliminates manual translation by providing a public CronSchedule API for immediate use.
The cron parser is limited to standard 5-field syntax, meaning it does not support 7-field expressions with seconds or years. It focuses strictly on minute, hour, day, month, and day-of-week fields with Vixie semantics and specific modifiers.
