[Lift] Re: How about a lift + sling marriage
Interesting view point... Lift has very good support for managing HTTP requests, so, by default - REST. Im currently writing a series of posts about various components in Lift and dispatching / rest was the next one on my list. Probably get around to writing it next week. Cheers, Tim On May 7, 9:29 pm, glenn gl...@exmbly.com wrote: You are probably correct about Sling's overall usefullness. I was thinking in terms of Slings native restful capabilities more so than Jackrabbit, without fully realizing that lift can do REST as well. Is there documentation, or a sample, that can show me how to use it? Here, the lift book is only partially helpful. There is an example of JSON form handling, but that's about it. Don't I need a REST server that can handle the GET, POST, DELETE, etc. commands and work with the the mapper objects?

There is suppose to be a scala bundle that can be used in Sling, but I haven't seen it. Does anyone know where to get it, or if it even exists. I took a look at Sling and see very little value in integration. Lift has the best REST handling out there. Multiple languages is a lose rather than a win. And anything that advertises itself as fun has an instance yellow flag from me. There would be a couple of reasons for wanting an integration - using the Jackrabbit repository for all your lift-enabled html Jackrabbit might be an interesting backing store for Lift and/or Lift content. It's pretty trivial to do this now with Lift. It's about 100 lines of code to use an external backing store for Lift content. and as an alternative to a relational db for model persistence. In addition, think of the mashups and gadgetization that would be possible with lift OSGi bundles. And we have an ongoing OSGi project within Lift, so an external one is not necessary. Obviously, a full integration would require changes to resource management, but nothing that seems insurmountable. If there was a compelling use case, I'd consider it more, but reviewing Sling, I can't seem to find one. I'm open to hearing thoughts on actual use cases. Sorry.

[Lift] Re: garbage collection
Can't you use a regular Java profiler to determine this? Perhaps would be beneficial to start thinking of a generic enough stats module that would reveal information like that to the lift applications.

After submit the inputs are tested and errors return a string with the

Is there a way to get the widget object after submit to set the values

use a tuple to return the widget object from the buildWidgetPackage
function.
Try using a StatefulSnippet (make your snippet a subclass of
StatefulSnippet). That will use the same snippet across form
submissions.
If you need a more detailed explanation, please let me know and I'll work
one up for you.

It would be something more like this:

The signature of the exception handler type is:

[Lift] Re: How to log exceptions?
Thanks for the help.
What I need might like this
LiftRules.exceptionHandler.prepend {
case (_, _, exception) = {
Log.error(exception.getStackTrace.toString)
RedirectResponse(/)
}
}

Your most welcome.

Log.error(exception.getStackTrace.toString)
RedirectResponse(/)
}
}
If that works for your needs, go for it. The only suggestion I might have is
that you might perhaps want to display something static to say about the
error (if for instance, your error occurred on the home page you'd have an
infinite loop)

[Lift] Locale/Language in URL?
Heyho, anyone has an idea how one might accomplish having the locale/language of the content in the url? since most search engines can't work with cookies and therefore change the language correctly, i wanted to go for URLs like /de/mystuff or /en/mystuff. I guess everyone gets the point. Any ideas how to do that without compromising the whole Sitemap feature? best regards! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Lift group.

[Lift] starship 'paratroper's
Lifted, Since there's another SOS conference coming up%20http://homepages.inf.ed.ac.uk/bklin/SOS2009/, i've decided to formally write up this really neat idea for reduction http://biosimilarity.blogspot.com/2009/04/law-of-attraction.htmlthat i discovered. To support the paper (i.e. provide an executable version of the mathematical model), i'm building out a lift project, cut from the same cloth as the rlambda project i did. Instead of a two-level type version of lambda, it's a two-level type version of Milner's π-calculus. This enables one to do the very same trick that Martin challenged us to with lambda, but this time with π-calculus. My plan is to flesh this one out with all the features i've been mumbling about: - concrete syntax and multi-target parser - two-level type-based abstract syntax - polymorphic reduction strategy support multiple different variable and environment representations - The final form of the reduction strategy will also include a version of Oleg's LogicT - persistent code model (XSD schema + BDBXML XQuery db) - query langage for the code model This seems like a reasonably rich example on which to base a lift archetype, that i would like to dub lift-DSL. As i mentioned before, the primary input to the archetype is a brief specification of a DSL. The output is a web-based REPL++. i believe such an archetype encapsulates the salient features of Microsoft's Oslo and extends them, but built out of parts you can just find lying around on the web. (Oops! Commoditized again! ;-) You can find the current project here http://code.google.com/p/paratrope/. The name comes from banging the two memes para - Greek origin meaning beside, near, past, beyond, or contrary A literary *trope* is a common pattern, themehttp://en.wikipedia.org/wiki/Theme_%28literature%29, motif http://en.wikipedia.org/wiki/Motif_%28narrative%29 in literature, or a figure of speech http://en.wikipedia.org/wiki/Figure_of_speech in which words are used in a sense different from their literal meaning.[*citation needed http://en.wikipedia.org/wiki/Wikipedia:Citation_needed*] The term *trope* derives from Greek http://en.wikipedia.org/wiki/Greek_language * τροπή http://en.wiktionary.org/wiki/%CF%84%CF%81%CE%BF%CF%80%CE%AE*turn, turning [1] http://en.wikipedia.org/wiki/Trope_%28literature%29#cite_note-0, from *τρόποςhttp://en.wiktionary.org/wiki/%CF%84%CF%81%CF%8C%CF%80%CE%BF%CF%82 * - *tropos* turn, direction, way[2]http://en.wikipedia.org/wiki/Trope_%28literature%29#cite_note-1related to the root of *τρέπω http://en.wiktionary.org/wiki/%CF%84%CF%81%CE%AD%CF%80%CF%89* - * trepō*, to turn, to direct, to alter, to change[3]http://en.wikipedia.org/wiki/Trope_%28literature%29#cite_note-2 . around in a mind whose formative years were spent dangerously overexposed to Robert Heinlein. To do this i need the following bits and bobs - Help writing a mvn plugin for BNFC - i started writing one, but got depressed about the complexity and never returned to the task - if anyone has a working mvn plugin written entirely in Scala, i could probably write mine from that -- i've just gotten to the point where if i want to get things done on the scale i'm trying to work i really need to limit the amount of Java i have to write - A dtd - xsd converter (and an xsd - SQL schema converter would be really, really nice) - A nice-to-have would be a LINQ-like interface on top of the BDBXML/Java interface, but i can make do without it i could also really use a code reviewer or two.
