Natural Language ➔ Lexical Tokenizer ➔ AST ➔ [Min] [Hour] [DOM] [Month] [DOW]
The NLP engine scans for temporal keywords (like 'midnight', 'weekend', 'hourly') and mathematically maps them to the corresponding integer constraints required by the cron daemon.
Migliori Pratiche e Linee Guida Essenziali
- Avoid Ambiguous Phrasing: A phrase like 'every day' is perfectly parsed to `0 0 * * *` (midnight). However, 'sometimes' or 'often' cannot be translated. You must provide explicit temporal boundaries.
- Verify the Output Before Deployment: Semantic parsers can occasionally misinterpret complex conjunctions (e.g., 'Mondays and Fridays in March'). Always double check the generated 5 part string before pasting it into your crontab.
- Understand the Limits of Cron: If you type 'every 30 seconds', the parser will fail or round up to one minute, because standard Unix cron cannot resolve sub minute intervals.
Domande Frequenti (FAQ)
What is an AST?
An Abstract Syntax Tree (AST) is a data structure used by compilers. The parser breaks your English sentence into an AST, identifying the 'action', the 'interval', and the 'constraints' before generating the final cron string.
Does this support non standard cron syntax?
The tool generates standard Unix syntax (5 fields). It does not automatically generate 6 field expressions (which include the Year) unless explicitly configured, as standard Linux daemons will reject them.
Can I do the reverse (Cron to English)?
Yes. Bi directional parsing is supported. You can paste a cryptic string like `0 12 * * 1,5` and the engine will instantly translate it back to 'At 12:00 PM, only on Monday and Friday'.
