Title: Feature request: add call pattern to (date-value)
Post by: TedWalther on April 19, 2015, 01:47:20 PM
It is true, I can do
Code Select
(apply date-value (now))

However, I have been working with Julian days for a while, and just generally doing date and time related stuff, and so I request that you add the call pattern:


Code Select

(date-value list)

Ex:
(date-value (now))


This is parallel to how arguments are dealt with in that
Code Select
format function, so it makes sense from a "principle of least surprise" perspective.

Thank you Lutz!  And, I tremble to ask it.  It is so easy to get the current date with (date-list (date-value))

But, for sake of consistency, would it slow anything down to let (date-list) do the same thing as (date-value) and (date)?  That is, give the current time in the appropriate format?

Woohoo!  One of newLisps great strengths is its consistency of interface.
