| Summary | Path! syntax and date! syntax clash |
|---|---|
| Description |
In the example below there is a demonstration of a date! syntax and path! syntax "clash". The question is whether this is intended and whether it is optimal. This is related to #2090. I would like to be able to define a path containing a complete date value in some cases. The last example is probably the worst since it is the hardest to amend. |
| Example code |
>> to block! [6/Nov/2013/17:43] == [6-Nov-2013/17:43] >> to block! 'a/6/Nov/2013/17:43 == [a 6 Nov 2013 17:43] >> to block! 'a/6-Nov-2013/17:43 == [a 6-Nov-2013 17:43] >> type? load mold to path! [19 Nov 2013 21:01:51] == date! |

If you are saying that you want the following to be equivalent
'a/6/Nov/2013/17:43 'a/6-Nov-2013/17:43 I'll say -1, because it could lead to unexpected results. i.e., how do I escape it if I happen to have path values that would unintentionally become a date? |

"If you are saying that you want the following to be equivalent..." - I am *not* saying that. I am saying that there is a "syntax clash" that causes problems. |

Ah, I think I see what you're saying now. You would have to put the date in a paren or something today. Do you have an idea for a cleaner solution?

The ISO date format does not "clash" with path syntax. Supporting ISO 8601 we will be better off in this sense as well. See #2092. Also, it is possible to use paren in path is some cases, which may be a way to circumvent the problem. |

I like that the slash in a date makes the time a refinement of the date, but it does clash in paths. I hesitate to suggest it, but "@" might be an understandable delimiter. It is non-standard, but reads well as "at" in this context. I also just found that REBOL can load it, thinking it's an email. e.g. 19-Nov-2013@12:30. Not all date forms load that way, and I very much doubt if anyone is using that feature that would complain about their code breaking.
That said, I can live with ISO8601, as I think it would be good to be able to load it in any case. I don't like the T, but the benefits may outweigh my feelings. :-) |

The benefits of ISO will be:
* standard compliance * improved compatibility between date syntax and path syntax |

Regarding "I like that the slash in a date makes the time a refinement of the date" - understood, but, actually, I do not like this "benefit":
>> type? load mold to path! [19 Nov 2013 21:01:51] == date! Also, this is not easy to amend. Any idea? |
