[Lift] Re: Packaging lift application for distribution

[David Pollak]

Thomas,

You can package Lift apps with OneJar and use the Winstone servlet container
(http://winstone.sourceforge.net/ )  That'll put everything in 1 JAR file
and it should allow single-click launch on a Windows machine.

Thanks,

David

[Lift] Re: migration tools?

[Meredith Gregory]

Tim,

Thanks for your note. i was largely referring to the possibility of sucking
on the data model (mainly from the db schema side, as the parsing would be
easier) to generate appropriate Model code.

Best wishes,

I'm guessing that Greg wants a tool that will read the DB scheme and
generate Lift Model classes.  Nothing does that right now, but if someone
wants to contribute such a tool, I'd love it! ;-)

[Lift] Re: migration tools?

[Tim Perrett]

Hey Greg,

I have taken great pleasure in porting several "leaking like a rusty bucket"
rails applications... Whilst there is no direct migration, once you
understand exactly how lift works, it becomes simple.

When you say "db stuff squirted out from ActiveRecord?" - what exactly do
you mean? Queries? To_xml stuff?

Cheers

Tim

[Lift] migration tools?

[Meredith Gregory]

Lifted,

Suppose one were to engage in porting a RoR app to a Lift app. Are there any
tools in the Scala+Lift arsenal that ease that migration? For example, is
there a nice path that allows to preserve the db stuff squirted out from
ActiveRecord? Is the are way to auto-generate some basic Model code from
that starting point?

More generally, have you guys been thinking about this direction? What about
migration from other sites?

Best wishes,

[Lift] Help on getting Eclipse/Maven/Lift working

[Thomas Sant Ana]

I followed the tutorial here on this page:

http://scala-blogs.org/2007/12/dynamic-web-applications-with-lift-and.html

And was pleased to see the application come out so quickly. However I have a
question. As I save the file on Eclipse they don't get picked up by Jetty. I
need to do a mvn install on the pom.xml of the eclipse project.  And
clearing the project on eclipse broke mvn install, until I did a mvn clean
then a mvn install.

The tutorial references to "incremental compiling". I've been working with
Scala  on Eclipse and got around most troubles myself. But the
Eclipse+Maven+Jetty+Lift is confusing for me. I have a set of questions:

a) How to get code compile incrementally on eclipse, picked up by jetty?

b) How do I debug the application from eclipse?

c) Is there a way to have it all running under eclipse?

I know these question may seem dumb, but I'm not finding good information on
google. Is there a "Developing for Lift using Eclipse for Dummies" arround?
The best I found what this tutorial.

Thomas

[Lift] Re: Menus with Submenus - can I have a top level menu as container only?

[Dano]

Did a little more digging into how Loc and MenuItem work together.  It
looks like the 'kids' of a menu item are not exposed until you click
on it.

I am looking to see if we can have behavior which exposes the 'kids'
of a MenuItem before clicking on it.

Subject: [scala] Jane Street Summer Program
To: Scala list 


This caught my eye and might be interesting to some Scalars out there.  This
year they aren't just focusing on OCaml.

=

The Jane Street Summer Project is aimed at encouraging growth in the
functional programming community by funding students over the summer to work
on open-source projects in various functional programming languages (with a
focus on our favorite language, OCaml). We do that by funding students and
faculty to work together over the summer to create software that makes it
easier for people who are using functional languages as an ends rather than
a means.

The JSSP is funded by Jane Street Capital . We make
extensive use of OCaml at Jane Street , and
it's in our interest to see the FP community thrive. Plus, we think it will
be fun.

For more detailed information, check out the faq!

[Lift] Re: Lift and Flex

[Michael]

I've used Lift quite a bit as REST back end for a Flex/Flash front
end. It is straightforward. Check out Steve Jenson's wiki page on
this: http://liftweb.net/index.php/HowTo_do_Web_Services if you
haven't seen it already. Scala's XML support makes it super easy to
create XML on the server, and E4X makes it easy to consume it on the
client.

I haven't tried Lift with remoting, but this looks promising:
http://flexonrails.net/?p=103 . It might be interesting to create an
AmfActor trait or such to create a tighter integration.

[Lift] Re: First steps: forms tutorial

[Derek Chen-Becker]

For the first error I think you need to import net.liftweb.js.JE._ to get
the implicit String => Str (JsExp) conversion into scope. On the second
error, your code seems to indicate that you're still using the "-->"
operator (I think it's deprecated) instead of "->" (one less dash). Please
fix that and try it again.

Also, if the class for the snippet couldn't be found, Lift should have
output a message to that effect on the console. If it didn't, then
*that's*a bug.

[Lift] Re: submit and redirect

[Derek Chen-Becker]

I think the convention is to either properly capitalize the snippet tag to
match the class name, as you've done, or to use underscores to indicate
camel case, a la

show_market

I don't think that Lift handles "mixed" camel case, but it's been a while
since I've looked at that part of the code.

 Yeah it does... in essence not very different from initial proposal
 since internally redirectTo from stateful snippet does the same thing:
 binds a function to be executed upon redirect.

Re: Fwd: [Lift] Cleaning up warnings

[etorreborre]

Hi David and Rickard,

If you replace property(...) by Prop.forAll(...), the warnings should
disappear.

On the other hand I don't know why forAll(...) only doesn't work.

Cheers,

Eric.

Re: Fwd: [Lift] Cleaning up warnings

[Rickard Nilsson]

It seems strange that forAll complains about getting a String => Boolean
function. It works fine in the interpreter. The only reason I can see for
that error message is that Scala somehow thinks that forAll is given two
parameter lists. There exists an overloaded version of forAll of type
[T](Gen[T)(T => Prop) => Prop.

I can try to check out the Lift code and investigate the warnings when  
I get some time for it.
