[Lift] rendering embedded svg
Lifted, Here http://svn.biosimilarity.com/src/open/GraphL/trunk/ you will find the source code for a Scala+Lift application in progress. It's a demonstration of a compositional (read algebraic datatype) for graphs. If you've got graphviz installed and the dot program on your path, then mvn jetty:run followed by pointing your browser at localhost:8080 should do the trick. (If not, i'd be grateful if you'd let me know what you do see.) In the current state of things, i've got a little repl with a small window in which to type expressions. Pressing the 'go' button evaluates the expr to a normal form for the graph and renders it as svg. However, what's happening currently is that instead of rendering the svg as a drawing it prints out the text of the svg. i note that if i point a browser at the svg (with header) it renders as a drawing. i also note that if i take the svg and put it inside a static lift page (with the lift:surround tag surrounding it) and add that to the site menu, it renders as a drawing. Obviously, i'm not doing something right in the REPLForm code. Any clues would be greatly appreciated. Best wishes, --greg -- L.G.

[Lift] Questions about User object and class
Lifted,
i'm looking at this code in
githubhttp://github.com/dpp/liftweb/tree/master/lift-mapper/src/main/scala/net/liftweb/mapper/ProtoUser.scala.
Lines 258 and 274 - 279 would indicate to me that an object derived from
this class -- as i think the User object is in the std lift project
archetype -- would be able to manipulate onLogOut. However, placing this
code
/**
* The singleton that has methods for accessing the database
*/
object User extends User with MetaMegaProtoUser[User, User with
KeyedMetaMapper[Long, User]] {
...
def wantsToKnow() : Boolean = {
this.onLogOut = (({ x = _wantsToKnow = false}) :: this.onLogOut)
_wantsToKnow
}
...
}
in the object's def results in this complaint
[WARNING]
/Users/lgm/work/src/projex/biosimilarity/GraphL/src/main/scala/com/biosimilarity/GraphL/model/User.scala:23:
error: value onLogOut is not a member of object
com.biosimilarity.GraphL.model.User
[WARNING] this.onLogOut = (({ x = _wantsToKnow = false}) ::
this.onLogOut)
[WARNING] ^
[WARNING] one error found
[INFO]
[ERROR] BUILD FAILURE
Also, what gives with the *two* type parameters to MetaMegaProtoUser --
which as declared in lift-util.mapper appears to take only 1 type parameter?
Clueless about lift, but still sending best wishes in the New Year,

[Lift] neophyte lift ajax question

[Lift] Re: neophyte lift ajax question
Chas,
That's exactly what i thought. But, that would be a bug -- unless i've
misunderstood something -- because, then the effect of the bind is bleeding
over into the behavior of the ajax form.

[Lift] Re: neophyte lift ajax question
Chas, et al,
To clarify
- Suppose you only had the ajax form in the site menu. You would never
call the bind. So, the namespace would not be set up and the form
should/would not work.
- Additionally, in the given sample application the behavior associated
to the widgets in HelloForm2 is not (necessarily) the behavior in the
ajaxform. So, that's also a source of confusing erroneous behavior, as i
expect the user to see the behavior from the bind.
- Furthermore, if you have the set up as in bullet one and make a call to
bind before returning the xml:group, you still get the unknown namespace
error.

[Lift] scalac java compilation
Scalads and lasses, i believe i've hit a bug in the scalac java compilation. i'm not 100% certain. To verify i need a way to tell scalac *not* to compile java files in the mvn build process for a lift app. i will briefly describe a portion of my build process. i'm building several DSLs. i use BNFC to rapid prototype the grammars the build the java parsers. Then i use the parsers in scala+lift applications. The reason i mention this is because BNFC squirts out a makefile to build the java. So, i've got a standalone build using gnu make just for the java parser. i can compare this to mvn build. The parser is included in the model part of a lift app and built using the mvn build system. i just made a change to a parser and verified it builds and works as a java parser. Then i essentially copied the working code into the lift app. Note, when i build my app with mvn i've got the javac compilation line configured to show the command line. So, when i hit the following error, i'm pretty sure this is coming from the scalac compiler. Since the file in question compiles just fine, i'm fairly certain this is a bug in scalac. i can make all the code available, but i really, really don't have the cycles just now to reduce this to a smallest test case. i don't have to be blocked it i can just stop scalac from compiling the java files.

David,
Excellent. i needed a nap anyway.
Best wishes,

P.S. Someone disappeared from the Seattle-Bainbridge ferry last night and
completely disrupted service. i spent 1.5 hours on the floor of the
Bainbridge ferry terminal and a little over 4 on a friend's living room
floor waiting for them to get the service up and running again -- so that i
could drive up to Vancouver to give a (lift) demo. Fortunately, i could do
the crucial bits of the demo using the scala console and it looks like there
was good reception. i think things will go over even better when i show them
a web wrapper for the core features.

David,
Well, i just nabbed that code from the liftweb site a day or two ago and
stuffed it into a shell script. i stared at the version number and wondered
whether that referred to the archetype version or the version of lift. Since
it was up on the site i reasoned it was the archetype version and was vetted

It is a bit annoying to have to wrap valid markup with a div just to make it insert it properly - my understanding is that this is a a side effect of the scala XML lib rather than lift code? I wonder if there is anything that can be done to make with-param a little more robust? Thougts? The lift:with-param/ tag has to be a child of the lift:surround/ tag.

Tony objected to the reputed Box is Option statement. There was a discussion about this on the Lift list. Tony gave no ground in any of the discussion (for example, when Jorge discussed the OO perspective) and was hostile and in my opinion, abusive. Near the end of the discussion, I stated that I did not recall stating that Box is Option but that Box is *like* Option, except... See http://groups.google.com/group/liftweb/msg/a5493a6a9180a37d So, the factually basis for Tony's position was gone. Did he apologize? Did he behave at all reasonably? No, he made a post (which I deleted because Tony's messages were moderated) which claimed that I had claimed identity between Box and Option but he was too lazy to find the post. [Turns out that during the thread, I made the statement, but I've searched previous posts on the Lift list and could not find myself or anybody else claiming that Box (or Can) was an Option.] Tony tried to discuss this [in his usual exacting style] but found himself banned from the Lift list, and tried talking to dpp about it, Actually, it was somewhat different than this. I had left a number of Tony's messages in the moderation queue. I contacted him privately many posts before I banned him and asked him to tone it down. Here's the text of my first private note: I'm not going to post your last two responses because you've crossed the line from being exacting to being abusive. I have a great deal of respect for you as a coder and as a thinker. But, your brand of argumentation does not have a place on the Lift list. Rather than showing any form of understanding what I was asking of him, Tony continued to behave in a manner that is inappropriate on the Lift list. I banned him from the Lift list. Tony continued to contact me privately. He did not contact me trying to understand why he was banned or to try to get unbanned. He continued to have the pointless discussion about Boxes and Options. only to get personal threats in return. I'll tell your employer. Yes, after the 3rd request from me to Tony to not contact me privately because the discussion was done, I told him that if he contacted me again, I would contact his employer. At least Tony stopped sending me email. So, that's the history from my perspective. Tony's the only substantive contributor to the Lift list who's ever been banned. I regret that the Lift community will not be able to benefit from Tony's remarkable approach to development. On the other hand, the Lift community is a warm and welcoming place and Tony's behavior chilled the place a whole lot. So... on to the substance of what I can read from Tony's comments. He's right. Lift is seriously lacking. While I still think it's the best web framework, it is seriously lacking. I am projecting the kind of issues that Greg Meredith is having with Lift. From reading the code that Tony and Greg have written, they have a similar coding style and I believe a similarly rigorous approach to design and development. Lift is a blend of FP and OO, stateless and stateful, transformative and imperative. And, as Lift gets closer to 1.0, I'm not sure that we got the balance right. Perhaps some sort of pi-calculus based way of describing web app logic would allow for better reasoning. I've noodled with doing some sort of stuff with pi-calculus in Lift.

[Lift] web logic
David, i just noticed this paragraph. Perhaps some sort of pi-calculus based way of describing web app logic would allow for better reasoning. I've noodled with doing some sort of stuff with pi-calculus in Lift. I stopped the exploration because I was unable to find reasonable language constructs to express what I wanted economically and in a way that a Rails or Struts or Wicket developer could pick up reasonably easily. But, I digress. i would have to agree with this assessment. The pi-calculus is a formal device. Just like the lambda calculus, it's a stripped down, minimal expression of some intuitions about computation (in pi's case, it's computation as interaction). That said, in the same way that lambda provides excellent guidance -- a blueprint, if you will -- for the basic design of languages like, Lisp, Scheme, OCaml, F#, Haskell and Scala, one might hope that the pi-calculus could provide some guidance or a blueprint for a new family of languages that is better suited to computing in a highly parallel, highly distributed setting, such as the web applications powered up on networks of racks and racks of multicore processors. Some examples of languages following largely similar intuitions as expressed in the pi-calculus include Erlang, Rosette and the actor sublanguage of Scala. People have already given a pi-calculus semantics to core Erlang. My PhD work was driven by my desire to give a similar account of Rosette. It took forever for me to work out a reasonable account of reflection -- which was a key feature of Rosette that i put to use in commercial, mission-critical applications. All that said, i would, and i think the whole community would also benefit from your experience and intuitions regarding what sort of language features have helped you and what didn't work out so well.

At this time, the XML team (apart from EPFL people, of course) consists of myself, Michael Fogus, Normen Müller and (I think) David Pollak, but contributions--including bug reports, patches, complaints, feature requests and existential angst--are of course welcome from everyone. On behalf of said team, I would like to invite everyone who is interested in Scala's XML support to join the new scala-xml list!

Here's some background info for anyone who is unfamiliar with Scala's XML support: The Scala compiler supports XML literals in Scala source files, with very few additional restrictions on their syntax. XML literals are translated into a tree built from instances of several classes in the scala.xml package ( http://www.scala-lang.org/docu/files/api/scala/xml$package.html), and may contain nested Scala expressions (each of which can also incorporate sub-nested XML literals, etc...) whose results are interpolated into the XML. The scala.xml.Node class and its descendants form a comparatively lightweight, immutable, DOM-like representation of XML that can be used in pattern matching and provide simple, XPath-like node selection queries. The package also contains a few parsers and other assorted tools. IMO we owe a debt of gratitude to Burak Emir, the primary developer of scala.xml. I believe he has laid a solid foundation that will serve us well. Burak also wrote http://burak.emir.googlepages.com/scalaxbook.docbk.html which gives insight into the rationale behind the design and implementation of the library. Now, let's kick off the list with a small agenda: 1) Bug triage Rather than list the (~18) known bugs here, I'll supply an URL ( http://lampsvn.epfl.decenturl.com/scala-xml-bugs), and anyone who feels like their favourite bug merits further discussion should fire up a new topic on scala-xml and we'll start hashing it out. If nobody pipes up I'll start posting individual emails regarding each bug with a few of my own comments in a few days. 2) Proposed enhancements I'm sure many of us have a wish list of things we would like to see changed in Scala's XML support--please feel free to join in and tell us all about them.

[Lift] basic lift question
Lifted,
Suppose i've got the following fragment of lift tags
lift:surround with=default at=content
!-- Begin Easy Widgets plugin HTML markup --
div
a onclick=AddWidget('widget1.html'); return false
href=# title=Add an activity align=right+ Create an activity/a
/div
...
/lift:surround
and i want the onclick to call into a lift snippet instead of my jQuery
function, AddWidget, as it does above. How would i rewrite the anchor tag?
Best wishes,
--greg

[Lift] Re: basic lift question
David,
Thanks for your on-going support! From the looks of your example, i'm
guessing that if i want to subsequently call some JavaScript to provide
visual feedback of the server-side behavior i do something more interesting
than the js.JsCmds.Noop in your code. However, i can't see exactly what i
should do. i went looking at the repo and found a comment to the effect
/**
* JavaScript Expressions. To see these in action, check out
* sites/example/src/webapp/json.html
*/
But that doesn't seem to exist in the repo. At least when i browse to
sites/example/src/ it contains nothing.
If you can just point me at some examples, i can probably work out most of
what i need.
Best wishes,
--greg

Do you want the onclick to invoke a function on the server when the a is
clicked?
If so:
SHtml.a(() = {println(Somebody clicked the link); js.JsCmds.Noop},
Text(Create an activity))
Should do the trick. You can put whatever you want in the function.

[Lift] Re: strange interaction with jQuery
Marius, Agreed on two points: - JsRaw is not the culprit -- it seems to be a bad interaction with version of JavaScript modules - JavaScript is the source of the meta problem -- there's no way to get the compiler to warn about this because this world is devoid of useful typing info. It would appear that a vast number of web technologies have accepted a programming model proposition that is predicated on typelessness. 'This has all happened before and it will happen again.' It looks like i'm going to have to resurrect my rhoscript project. Best wishes, --greg On Sat, Feb 14, 2009 at 2:20 PM, Marius marius.dan...@gmail.com wrote: Interesting ... When dragging I'm getting a JS error in jquery-ui.js: $.Event is not a function ... which appears to cause the odd behavior. I'm not sure yet why this error appears. BUt I found that this may appear when you have incompatible versions of jquery and jquery ui, Perhaps try here? http://groups.google.com/group/jquery-ui/browse_thread/thread/8fbe3061bd567e2f/a19f7e874ea48e74?lnk=raot I really do not think that JsRaw has anything to do with this. It fails even if you have a plain link in the page ... pretty much like in the static example. I don't think there is a way of detecting such behavioral things at compile time. Br's, Marius On Feb 13, 10:38 pm, Meredith Gregory lgreg.mered...@gmail.com wrote: Lifted, Attached is a minimal example of a strange interaction between lift and a jQuery plugin. If you unzip the example you will find inside the liftTestCase directory 5 subdirectories two of which contain behaviors to compare. The directory 23 contains an example that is purely jQuery with the EasyWidgets plugin. The directory dspace contains a lift-based site. If you open 23/index.html in a browser you will see a page that allows you to add widgets that can be dragged and dropped around. This all works. If you cd into dspace and launch mvn jetty:run, sign up, login, then you will see a boiled down version of the same thing. The difference is that the javascript jQuery call is run as a JsRaw. Everything seems to work except you attempt to drag and drop the components. Then you get very weird behavior that is easier to see than to describe. The thing is, we haven't actually done any interesting lift stuff, yet, in the boiled down sample. We're just calling into the EasyWidgets function just like in the sample. i would expect these two examples to exhibit nearly identical behavior. i'm guessing there's some weird interaction between lift-included javascript and the jQuery plugin. Several questions: - How could we devise a way to check at compile time that there is such an interaction? This seems to be a crucial point as the momentum is to use third party frontend web components. - What is the best way to go about finding the interaction if it has escaped compile time detection?

Greg,
You experienced a progression, not a regression. :-)
I tightened up the Lift security model a little bit such that Lift will not
pass requests to the Servlet container just because the request was not
found in sitemap.
So, what you can do is define a pattern that excludes the widget1.html,
etc. files from being serviced by Lift. Lift will pass the request right
onto the container and all will work as you expect. In Boot:
LiftRules.liftRequest.append {
case Req(n :: Nil, _, _) if n.startsWith(widget) n != widgets
= false
}

Wow... it's been a long and fun experience... and today the dozen plus Lift committers and the whole Lift community together are releasing Lift 1.0. Lift is an expressive elegant web framework based on the Scalahttp://scala-lang.org/programming language and released under an an Apache 2.0 license. Lift provides developers the best way to build interactive, high performance web applications. Lift based applications are deployed as WAR files into J2EE containers such as Jetty, Tomcat, and WebLogic. Lift based applications are high performance and can make use of your existing Java libraries. I could wax on for hours about: - Lift's Comet and Ajax support which allows you to build real-time interactive applications - Lift's concise code allowing developer productivity normally associated with Rails and TurboGears - Lift's high performance and scalability - Lift's built-in support for REST and other web services - Lift's use of Scala's type-safety so your tests can focus on business logic But, that's not the most impressive thing about Lift. Lift is powered by a community of committers and users that cares about building tools for building great web apps. Lift is impressive because of the people who use, drive, enhance and exchange ideas about Lift. The Lift community is a warm, welcoming place for people of all backgrounds. The Lift community and Lift committers strive to learn from others and roll that learning into Lift and their own projects. That's my take on what makes Lift great, but let's hear what other have to say about Lift: The interest and excitement about Scala continues to grow. It's great to see Lift reaching the 1.0 milestone as this is a proof point for the maturity of Scala as a software platform. Martin Odersky http://lamp.epfl.ch/%7Eodersky/, ACM Fellow, Father of Scala Lift is the only new framework in the last four years to offer fresh and innovative approaches to web development. It's not just some incremental improvements over the status quo, it redefines the state of the art. If you are a web developer, you should learn Lift. Even if you don't wind up using it everyday, it will change the way you approach web applications. Michael Galpinhttp://www.ibm.com/developerworks/opensource/library/os-ag-lift/#author, Developer, eBay The slight added complexity of static typing is more than offset by the performance, scalability, and the benefits of type safety. Lift is maturing rapidly and has already proven itself many times over, and it will only get better. As much as I liked Ruby and Rails, I like Scala and Lift better. After more than two years of developing software in Ruby/Rails, we've shifted all our development efforts to Scala/Lift. And we are not looking back. Charles Munat, Lightsource Interactivehttp://lightsourceinteractive.com/ Lift's excellent 'Comet made easy' philosophy made it an absolute no-brainer as the choice of framework for the Apache ESME project. Additionally, the fact that Lift-based applications run unchanged on the SAP's NetWeaver CE Java application server makes this an intriguing approach for enterprise applications in the SAP world. Darren Hague, SAP Mentor, ESME http://blog.esme.us/ team lead When I decided to put Innovation Games http://buyafeature.com/® online, I knew that I couldn't afford a massive development effort. I needed a small, sharp team who could leverage best-in-class tools to help us solve the problems we knew that we'd have to solve in creating a new kind of collaborative gaming experience on the web. David suggested Lift and Scala and initial testing proved that we could realize the developer efficiency and backend scalability that we felt was required to efficiently support thousands of simultaneous games. We're now very comfortable with Lift and Scala and are pleased with how the solution framework continues to evolve to meet our needs. While we've used lift to push the boundaries of interactive web design, I strongly recommend anyone who wants to build a compelling web experience using an elegant framework to consider using Lift. Luke Hohmann, CEO, Enthiosys http://enthiosys.com/ If you're looking for a web framework on a strongly typed functional language and the JVM, Lift is the only game in town. Oh, and it just works, too. L.G. Meredith, Managing Partner, Biosimilarity LLC For me it's mainly because Lift represents collective web wisdom - all lessons
[Lift] java parser?

[Lift] Re: java parser?
Lifted, FYI -- the google codebase javaproject has some interesting challenges to be used with scala/lift project. 1. binary not compiled with same version of the java compiler 2. sources not utf-8 Nothing insurmountable, but colluding to make the usage experience less than optimal. One interesting result of the non-utf-8ness: after a certain number of warnings from the scala built-in java compiler the mvn build process just craps out with no error reportage. It just falls over.

[Lift] Re: OS X lift installer
Jon,
No. There are at least two options -- both of which i use.
- once mvn has cached stuff you can run offline with the -o option
- you can also deploy jars to a local repo which can be a directory
resource or your own cloud resource
- i have a little shell script deploy-jar.sh i use to deploy to a common
place in my project structure // see listing below
- i add the following repo structure to my pom.xml
repository
idlocal-repo/id
urlfile://${basedir}/vendor/lib/url
/repository
- after i am happy that i've got the right dependencies, i push my local
repo up to my own cloud resource
cat deploy-jar.sh
#! /bin/sh
mvn deploy:deploy-file -Durl=file://`pwd`/vendor/lib -DrepositoryId=basedir
-Dfile=$1.jar -DgroupId=$2 -DartifactId=$1 -Dversion=$3 -Dpackaging=jar

Jon,
i'm not sure if you are talking about some specific lift installer,
and
i'm
no maven expert, but i use it and lift on my macbook pro. i think of
mvn
as
a make that is aware of the web (and whose language for expressing
rules
is
incredibly verbose). Being aware of the web, mvn allows project build
configurations to express dependencies on repositories in the
cloud.
These
it downloads and caches to ~/.m2 -- unless you configure it
otherwise.
Nine
times out of ten, it dependencies are jars that are mentioned as
dependency tags in the pom.xml file in your project. It is then
able to
configure the classpath for the JVM targets (like compile). If you
put
dependencies on other technologies, e.g. a container like jetty, and
use
those maven plugin goals you will be launching and running those
servers.
So... putting it together in terms of a usage scenario

[Lift] Re: chaining servlets
PPS The reason i want Jersey on the outbound path is that it has pretty nifty support for rendering to XML and other formats. A single Produces annotation at the class level, for example, suffices to cause all the web methods to render according to format specified in the annotation. Oh, and Jersey also autogenerates the WADL description of the service -- which is going to come in handy for other stuff we're doing. On Mon, Mar 2, 2009 at 3:16 PM, Meredith Gregory lgreg.mered...@gmail.comwrote: Tim, et al, Thanks for the many responses. Here's the overall context. i've got a group that has done some significant work building a JRoR site. Now they want to scale. As a part of a midterm strategy to get some reasonable tooling in, we're building Scala-based RESTful APIs. Being an idiot, i want as general a soln as possible. So, here's what i've done. - a plain, vanilla Hibernate reverse engineering strategy will fetch both JPA and simple POJOs - This gets me Scala access to the backend - Now, i want to generate default controller behavior. i've written a Scala program that eats what Hibernate spits out and creates default controller behavior. It uses the Jersey annotations (Produces, Consumes, Path, GET, PUT,...) to control rendering to/from the client of the RESTful API What i want to do now is to interject lift into the mix so that we can allow programmers to specialize the controller behavior in scala/lift code. The reason i've attempted to be fairly generic about all this is that i believe this represents a tool-chain that allows a semi-automated migration path from pick-you-webframework to lift/scala. The idea is that the SQL schema is about 80% of where the rubber meets the road, so that ought to be the place to hoist your app out of some existing solution. This works especially well if you're transition from a JVM soln (JRoR) to a JVM soln.

[Lift] really stupid maven question
Lifted, i've got all the classes i generate making a class to a Model object derived from the nice work that Derek did on the JPA demo. Now, here's the rub. For some reason it's compiling the generated classes before tackling the compilation of the model object. So... the compilation craps out. i've been working around this by generating the classes, compiling the project (without the classes) then moving them into place in the model directory and compiling the project again. What's the pretty way to enforce this sequentialization in maven. i really want these classes compiled *after* the Model.scala file is compiled. i'd like not to say much more than this ordering constraint to maven -- if at all possible.

[Lift] Re: [Jersey] jersey as filter
Alex, Thanks for all your help. i switched versions in the pom.xml (to 1.0.2 which is the most recent on the sun repo that is not labeled SNAPSHOT) and i get the right values from reflecting (BTW -- has anybody written a little lift browser app that hooks into reflection so that one can graphically browse the class/instances in memory?). Now i just need to figure out how to pass the resources context to Jersey. It's got a config for the ServletContainer class, but i don't see anything if i'm just using it as a filter.

meant to be used in the configuration section of your maven-scala-plugin
defintion section in your pom. Maven has some sugar to allow environment
variables to replace these configuraiton variables, using something like
-Dmaven.scala-plugin.args=... I'll have to look this up, but for now
please use the pom file or Jean-Luc's suggestion.

the -Dargs parameter is labelled as compiler additionnals arguments in

Moreover, from the source code :
step 1 : a scala class is generated in ./target/.scalaScriptGen ; it looks
like this :
class embeddedScript_1 {
// your script content here
Thread.sleep(1)
}
step 2 : it is executed here :
http://scala-tools.org/mvnsites/maven-scala-plugin/xref/org/scala_tools/maven/ScalaScriptMojo.html#172
step 3 : the temp files are removed
The only way I see to get some external parameter is using something like
System.getProperty(args) in yourscript.scala with a
-DscriptFile=yourscript.scala

Scalads, lasses and Lifted,
i clearly don't understand the mvn scala:script widget. This just works
scala -classpath $MYSCRIPTCLASSPATH scripts/GenerateFiles.scala
/Users/lgm/work/src/projex/bobj/dspace/src/main/java/com/sap/dspace/model/constellation/
(where MYSCRIPTCLASSPATH was set with and export to the value generated
by a mvn compile with appropriate verbosity on). But this doesn't
mvn scala:script -DscriptFile=scripts/GenerateFiles.scala
-Dargs=src/main/java/com/sap/dspace/model/constellation/
The latter complains -- as in the message below -- that 'args' is not
defined.

[Lift] Re: [Jersey] jersey as filter
Viktor, et al,
Well, i've scoped things down to just running the Jersey helloworld-webapp
sample in jetty with Jersey as the ServletContainer, rather than a Filter.
Even that is displaying the same behavior where the server is eating the
requests, but it's not hitting the resource class get method. Frankly, i
can't see a substantive difference between their sample and the one i've got
-- apart from swapping out glassfish for jetty.

[Lift] jersey and lift side-by-side + request for link to URL rewrite example
Viktor, et al,
i don't know if anyone's still interested in this thread... but it turns out
i was missing the contextPath in the jetty plugin config. Setting that
enables the two filters to run side-by-side. Now, on to better things...
what's the best lift sample for the URL rewrite machinery? The simpler the
better for a bear of very little brains, like myself.

[Lift] generic programming question
Mein Scalan und Liften,
Please find below a very simplistic view of transform a POJO to an XML
container. At it's heart is the recognition that a POJO is an in-memory
representation of a relation. i would like to generalize this code to
include other container types, e.g. JSON. i started down the path of
abstracting the type for the container, but realized the container ctor
might -- as in the case of XML -- have a reliance on some outer
context/scope. (In the case of XML the scala Elem ctor requires arguments
like a namebinding scope and a prefix and a bunch of other things.) So, the
abstraction along the lines of requiring that the container have a
prototypical object that supported an apply method became a prohibitively
complex design pattern. My question then, is what's a simpler design pattern
that will
- keep the core design principle that what we really have here is a monad
(more accurately a monad transformer -- the POJO itself is really a monad
and the code to change the shape is a means of transforming one kind of
comprehension/monad to another)
- allow for a wider range of possible target container types (XML, JSON,
kinda-separated-lists[1], dump format for MySQL,...)
Best wishes,
--greg

found in the wild, kinda-separated-lists occur everywhere where programs and
other creatures might dump data and forget a comma or two or...

[Lift] Re: [Jersey] jersey as filter
Paul, Many thanks for your note. i've been endeavoring to run Jersey and Lift in a filter chain. i was not seeing the requests passed on into Lift. Your explanation fits. What i really need is httpreq -- jersey -- lift -- jersey -- httpresp i can just hack this up myself, or i can log an issue (or both). Best wishes, --greg On Mon, Mar 9, 2009 at 1:39 AM, Paul Sandoz paul.san...@sun.com wrote: Hi Greg, I hope you have resolved things. I have been away on holiday, hence my silence. For Jersey 1.0.2 the Jersey filter support requires that the filter be configured at the end of the filter chain, see: https://jersey.dev.java.net/source/browse/*checkout*/jersey/tags/jersey-1.0.2/api/jersey/com/sun/jersey/spi/container/servlet/ServletContainer.html This is somewhat limited because we added this feature very close to the Jersey release. For Jersey 1.0.3-SNAPSHOT one can declare a regex that if matched defers to the next filter in the chain. See the Bookstore sample for more details on such a configuration: http://download.java.net/maven/2/com/sun/jersey/samples/bookstore/1.0.3-SNAPSHOT/bookstore-1.0.3-SNAPSHOT-project.zip We do not currently support a filter that passes things through to the next filter in the chain if Jersey does not match the URI. If you require this functionality please log an issue. Hope that helps, Paul.

David, Your screencast is very well done. There is one small change i would make to add a layer regarding the management of complexity. Make a change to the app: a small but noticeable change, like reorder the messages newest to oldest with a timestamp, or something. It would be ideal if somewhere in your modification you commit an error that is subsequently caught by typing. These two basic points dovetail nicely into a crucial point that Bill Venner's makes in his JavaOne presentation: types don't prove your program correct; types prove changes to your program correct. i think you could increase the bang-for-buck by a factor of 2 while only adding 15 - 20 secs to the time.

[Lift] namespace problem again
Lifted,
i'm getting the following error. i've run into this before and resolved it,
but i can't for the life of me remember what i did. All my other lift sites
are constructed pretty much isomorphic to this one. Any help would be
greatly appreciated.

[Lift] Re: namespace problem again
Lifted,
It appears that the interface for binding a namespace is side-effecting.
That's fine. But, i can't seem to understand the semantics. For example,
- if one puts a call to bind at the beginning of a block for a method
that handles a post, and yet returns a different nodeseq, the desired effect
is not present.
- If one nests the bind call inside the construction of a nodeseq, the
effect is not present.
- On the other hand, if one puts a call to bind on a completely different
form, the desired effect is present in the post handler.
i find that a little confusing. Is there a clean, simple model that will
help me understand how to use bind?
Best wishes,

[Lift] Re: namespace problem again
Lifted,
Sorry for the sound and fury. i found the soln again: the following call had
gotten mangled in boot
LiftRules.addToPackages(com.biosimilarity.weather)
That's a nasty one to get wrong. No help from the compiler. Error message
completely misleading.

[Lift] Re: namespace problem again
David,
Thanks, as always, for your responsiveness. i don't know if you saw my
earlier post, but i found and fixed the problem. However, now i'm running
into a more subtle problem related to how the JSRaw is handled. See below.
Best wishes,
--greg
Here's the error according to firebug
F507651869906K3V is not defined
onclick(click clientX=479, clientY=201)6FsTX8d6...J7Q%3D%3D (line 2)
(F507651869906K3V, lift_ajaxHand...TimeField).attr(value), null, null));
function onclick(event) { (F507651869906K3V,
lift_ajaxHandler(F507651869906K3V= + $(#initialTimeField).attr(value)
+ -- + $(#finalTimeField).attr(value), null, null));
}
The code that causes this problem is the handler for the onclick event for
the button. As near as i can tell, my raw JS is fine. This seems to have to
do with how the JsRaw is generating the onclick code.
def show(xhtml: NodeSeq): NodeSeq = {
xml:group
label for=initialTimeFieldInital time :/label
{ text(Now, (updateInitialTime _)) % (size - 60) % (id -
initialTimeField) }
br/
label for=finalTimeFieldFinal time :/label
{ text(Now, (updateFinalTime _)) % (size - 60) % (id -
finalTimeField) }
br/
{ button type=button{?(Go)}/button %
(onclick -
ajaxCall(JsRaw($('#initialTimeField').attr('value')+'--'+$('#finalTimeField').attr('value')),
s = updateChart(s))) }
br/

[Lift] really basic lift question
Charles, et al, i'm trying to do something dead simple and it is exposing all kinds of ignorance on my part regarding lift. (Yay! i get to learn new stuff -- which would be great if i weren't under a terrible time crunch.) Now, all i want to do is create a form with - 3 text boxes - 1 submit button - and an area for rendering a chart that results from a computation on the values of the text boxes Here's the minor complication. The submit is going to kick off a process that may be quite long running. So, i'll render immediately what's possible with the existing data and then when the long-running computation gets back to me i'll refresh the feedback. i thought this would be a poster-child app for the comet support. But, i'm realizing i don't really understand how - bind - text - submit - ... work and i find it difficult to navigate to their defns. For example, suppose i want the submit button to be greyed-out and inactive unless the 3 text boxes have validated input in them. What is the simplest pair of a snippet and controller that will do that? Best wishes, --greg -- L.G.

[Lift] buttons and textbox
Lifted,
i'm putting together a little lift-based testharness in which to evaluate
various solutions to the challenge Martin posted recently regarding scalable
abstractions for a little lambda interpreter. You can get a copy of the app
here http://svn.biosimilarity.com/src/open/rlambda/trunk/. (Please note:
this is a testharness and not a proposed solution. i've got a couple of
solutions in mind, but before i post them, i'd like to put them in a web
container.) As usual, i'm running into problems on the frontend. i'm not
getting expected callback behavior, and, moreover, the code i'm using used
to work fine.
The snippet code is included below this email's closing. The relevant
fragment is listed just below. The behavior i see is that the button
produces no behavior on the server at all. The CR/LF event on the text field
causes updateWhat to be called twice. Any advice on the frontend behavior
would be greatly appreciated.

theTerm = termStr

[Lift] Re: buttons and textbox
Lifted,
When i look at the button behavior using firebug, this is the following
error i see.
F891109765602PT1 is not defined
onclick(click clientX=950, clientY=152)1tbfBLwe...6bg%3D%3D (line 2)
(F891109765602PT1, lift_ajaxHand...whatField).attr(value), null, null));
It would appear that however the
ajaxCall(JsRaw($('#whatField').attr('value'))
is working it is setting up a handle that is stale by the time the behavior
is actually invoked. This is behind-the-scenes stuff for a programmer like
me. It's part of what lift is s'posed to provide. Moreover, i get no help
from the compiler. The code i have written is well-typed. Any help would be
greatly appreciated.
Best wishes,

[Lift] Re: buttons and textbox
Marius,
Thanks! That works much better. One final question, if i wanted to have the
CR/LF event on the textbox have the same behavior as the button, what would
be the simplest approach? Currently, i have
{ text(evalStr(), (updateWhat _)) % (size - 60) % (id - whatField)
}
which always reverts back to the initla value of the textbox.
Best wishes,

First of all instead of:
(onclick - ajaxCall(JsRaw($('#whatField').attr('value')), s =
updateWhat(s))._2)
I would use:
(onclick - ajaxCall(ValById(whatField), s = updateWhat(s))._2)
That should work I think in your case you are setting the value
attribute of the text field to lambda.x.x and $('#whatField').attr
('value') is just returning the 'value' attribute of the whatField
node. This returns the value set statically which is different from
document.getElementById(whatField).value. I know it's a bit odd ...

Marius,
Thanks for the tip! That gets me a little further. However, what i really
don't understand is why it is that after i have modified the textbox from
lambda x.x to lambda x.(x x), then when i type
$('#whatField').attr('value') in the javascript evaluation window in
firebug
it's returning lambda x.x. How do i access the contents of the textbox
except by that call?

ajaxCall returns a tuple (String, JsExp) ... so when you use it try

[Lift] 1st draft of response to Martin's code challenge for scalable componentized lambda evaluator
Lifted, Scalad and lasses, Recently Martin passed along a little code challenge regarding scalable abstractions for building a little lambda calculus evaluator. i've finally put together a 1st draft response. i've still got a lot of debugging to do, but the solution http://code.google.com/p/rlambda/source/browse/trunk/ is end-to-end. - there is a parser and evaluator hosted inside a lift-based web-container - the parser is built using BNFC and can target Java/C#/OCaml/Haskell/F#/... - the parser comes with visitor pattern support - the evaluator is built in a two-level type style and demonstrates that the only OO you need is just enough to make Scala happy -- the abstractions are all FP-based As i said, this is very much a draft and the code falls over most of the time. But, at this point, it's really a pedagogical device and framework for hosting and evaluating different solutions. Again, one the main reasons i see for using Scala is it's seamless interop with Java. The OCaml solution is intriguing (though ther are some strangenesses in it that i've yet to grok), but i would like to see that solution hosted in this manner. Best wishes, --greg -- L.G.

[Lift] Re: 1st draft of response to Martin's code challenge for scalable componentized lambda evaluator
Marius, Thanks for the query. Yes, there is a not so subtle point. Take a look at the grammarhttp://code.google.com/p/rlambda/source/browse/trunk/src/main/bnfc/rlambda.cf. To my way of thinking, these are it's advantages. - Readable (and therefore maintainable) - Targets the following languages with only 1 small change to the build process - Java -- therefore available in Scala, but faster than Scala - C/C++ - C# - F# - OCaml - Haskell - XML - Generates visitor patterns i find the parser combinator stuff certainly idiosyncratic, but nearly unreadable. i also note that in Haskell, the language (community) that originated the parser combinator stuff, the parser combinator machinery is nicely hidden behind a more standard BNF frontend, such as Alex + Happy. This is the way it should be.

But, at this point, it's really a pedagogical device and framework for hosting and evaluating different solutions. Again, one the main reasons i see for using Scala is it's seamless interop with Java. The OCaml solution is intriguing (though ther are some strangenesses in it that i've yet to grok), but i would like to see that solution hosted in this manner. Best wishes, --greg -- L.G.
