Hi All,
3 months ago Fabien Carrion has contribued some interesting patches. One of them is https://issues.apache.org/jira/browse/OFBIZ-1249 David asked <<Jacques: don't be too quick on this one please; we should do a design and requirements brainstorming discussion on the dev list before putting this in. The main thing I'm wondering is if there are other similar requirements that could be satisfied by small changes in the design of this.>> I would like to commit this patch now except if we begin to exchange about new requirements per David suggestion Thanks Jacques |

This really needs to go through a Calendar object instead of being cast to a long. Also, I don't think the current <calculate> element structure is best suited for the operations that would be most beneficial for date/time calculations

I agree with Chris. I haven't looked at the issue lately, but when I first looked at it, it simply performed millisecond arithmetic. That might not be the expected behavior.
Date calculation would be a great addition to mini language. Maybe we should discuss how it would look in mini lang code, then an implementation could be submitted. -Adrian Jacques Le Roux <[hidden email]> wrote: Thanks Chris, Interesting remark, seems that the disussion begins to roll...

Thanks Adrian,
I put your comment and Chris's in the issue. Hopefully Fabien will take care of it (propose somehting), else we will see later... Jacques De : "Adrian Crum" <[hidden email]> > I agree with Chris.

Thanks Jacques.
I've been thinking about this a little, and here is my suggestion: <adjust-date-time from-field="fromDate" to-field="toDate" years="+1" months="+1" ... millis="+1" locale="parameters.locale" time-zone="parameters.timeZone"/> The to-field attribute would be optional, as well as any of the adjusters. An <adjust-date-time> element that has no adjusters produces an error. Adjustments would be performed using the minilang context's locale and time zone, unless the locale and time-zone attributes are used. Any thoughts? -Adrian Jacques Le Roux wrote: > Thanks Adrian, > > I put your comment and Chris's in the issue.

Adrian,
looks pretty good. One small suggestion: use "field" instead of "to-field" to use the same convention of the set operator: <adjust-date-time field="toDate" from-field="fromDate" years="+1" months="+1" ... millis="+1" locale="parameters.locale" time-zone="parameters.timeZone"/> Jacopo Adrian Crum wrote: > Thanks Jacques. > > I've been thinking about this a little, and here is my suggestion: > > <adjust-date-time from-field="fromDate" to-field="toDate" > years="+1" months="+1" ... millis="+1" > locale="parameters.locale" time-zone="parameters.timeZone"/> > > The to-field attribute would be optional, as well as any of the > adjusters.

Keep in mind there are additional outputs that one might want from date/time math. Weekday of first of month, week of year, etc. I'm lacking moments of inspiration on the subject at the moment, so I'll just put that out there for now instead of offering a solution :P

Chris,
I agree! I'd like to see minilang develop to the point where we don't need the day.bsh, week.bsh, and month.bsh files in Workeffort. -Adrian Chris Howe wrote: > Keep in mind there are additional outputs that one might want from date/time math.

What about wrapping joda time (joda-time.sourceforge.net) up in mini-lang?

Jim,
That looks very interesting! We already have the UtilDateTime class that does pretty much the same thing.

Re: Calculate on a DATE object in minilang

What if somebody want to do this:
<adjust-date-time field="xDate" from-field="nowTimestamp" days="x"/> <format-date field="xName" from-field="xDate" format="EEEE"/> <log level="always" message="X days is ${xName}"/> Output: "X days is Wednesday" We may want to add a field to the current date. Would it be possible?

In reply to this post by Jacopo Cappellato
This looks good. I just have a couple of thoughts that might make this more consistent and generic: 1. instead of "adjust-date-time" maybe "set-calendar" would be more useful, and make it as much as possible a variation on the current set operation, or alternatively call it "calculate-calendar" and make it as much as possible a variation on the calculate operation 2. I really like the format-date idea, so much that I think we should make it even more generic and call it "format" or something, and allow a format string (might need another attribute name... maybe "pattern"?) and use that based on the type of the "field" object to convert it to a string; Ooops, never mind on number 2. I thought it sounded familiar... the current "to-string" operation should take care of it, and can be extended if needed for this particular use. -David On Dec 10, 2007, at 10:18 AM, Jacopo Cappellato wrote: > It would be nice to have: > > <adjust-date-time field="tomorrowDate" from-field="nowTimestamp" > days="+1"/> > <format-date field="tomorrowName" from-field="tomorrowDate" > format="EEEE"/> > <log level="always" message="Tomorrow is ${tomorrowName}"/> > > Output: > > "Tomorrow is Wednesday" > > Jacopo > > Chris Howe wrote: >> Keep in mind there are additional outputs that one might want from >> date/time math.

I just had a cursory review, yes seems like a good idea. I agree with Adrian view : rely on joda team as possible. And maybe help

Re: Calculate on a DATE object in minilang

I'm keeping this thread alive because I have a wish to see the
<set-calendar> (or <adjust-date-time>) operation implemented: in fact in the Minilang service I've committed yesterday to close a financial time period we have the requirement to get a Timestamp (older than an existing one of a few seconds). I'm wondering if someone here could help with this task... maybe Adrian "The Lord Of Time" Crum? ;-) Jacopo Jacques Le Roux wrote: > I just had a cursory review, yes seems like a good idea.

Re: Calculate on a DATE object in minilang

We should 1st create a Jira issue for this, isn'it (maybe there is already one) ? I guess your example is a good base for that using
all adjusters Adrian proposed years="${year}"... millis="${millis}". Adrian proposed that the field "field=" could be optionnal, so the adjusters fields, but there must be at least one of them (including "field=" in them ?) I don't think a such a rule is already used in minilang.

Jacques,
If you go back to the start of this thread, you will see that there is an existing Jira issue. Jacopo, I would be happy to work on this. It would help if someone could C&P the minilang format we discussed into the Jira issue, then I will work on it as soon as I'm done with a project at work. -Adrian Jacques Le Roux wrote: > We should 1st create a Jira issue for this, isn'it (maybe there is already one) ?
