XQuery templating engines and TXQ

"...separating logic from presentation" is good thing; and you don`t need much presentation before code can start looking a bit messy. Here is an example of mine at about the limit of what I feel comfortable with.

Landscape

I have been using Node.js a bit recently and it has an impressive list of templating engines. One of the things I like about Node is the module ecosystem; where vast numbers of different approaches compete in Darwinian fashion for "developer mind share". For reasons that I can't quite remember, I ended up using EJS with custom delimiters of single { and }. It looks a bit like XQuery.

When it comes to XQuery there are not so many choices :-). Maybe most are mentioned in this thread: eXist MVC and separating XHTML templates from XQuery code More recently eXistdb has Exist html templates. This looks to be standard XQuery 3.0 and provide a lot of high level functionality, but very much linked into the eXistdb environment.

What the world needs now is...

.. another XQuery templating system. So from my experience with EJS and express.js. Some features that I liked are:

A render method to take a view and a map type object to produce a page
A location, a collection or folder, for templates (views) completely separated from the code.
A quick syntax to wrap common page features around rendered results.
A block/partial/repeat type concept for list/tables.

Looking for the simplest thing that might possibly work..Noting that:

A XML document is a valid XQuery program.
If we put some {$var} type expressions in it and get XQuery to evaluate it in the right context- we are almost there.
BaseX has a (non-standard) function xquery:invoke that has just the right signature.

The start..

	declare function txq:render($template,$map){
	xquery:invoke($template,$map)
	}

With this view1.xml template

<div>{$greeting} {$who}</div>

Invoking..

	txq:render("view1.xml",map{"greeting":="hello","who":="world"})

	(: result :)
	<div>hello world</div>

Layout pages use the convention that a layout template has a $body field into which the sub template will be inserted

	(:~
	: template function with wrapping layout
	: @param layout
	: @return updated doc from map
	:)
	declare function render($template as xs:string,$map as map(*),
	$layout as xs:string){
	let $content:=render($template,$map)
	let $map:=map:new(($map,map{"body":=$content}))
	return render($layout,$map)
	};

	<head><title>{$title}</title>
	<script src="...."></script>

	<div>..nav bar..</div>
	{$body}

	<div>..nav bar..</div>
	<div>hello world</div>
	</body>
	</html>

Often there is a need to render repeated items from some node collection. A solution to this repeatedly invoke a sub-template, injecting a map with an item set to each node in turn. For example our map has a "actions" value. An XML node with a variable number of <generate> sub nodes that we wish to render.

	<div>
	<h2>{$heading} - {count($actions/generate)}</h2>
	<p>Actions are processes that generate a new item from an existing item.</p>
	<div>
	{$partial("action1.xml","action",$actions/generate )}
	</div>
	</div>

	<div>
	<h3>{$action/@id/string()}</h3>
	<span class="label">{$action/@in/string()}</span> → <span class="label">{$action/@out/string()}</span>
	<p>{$action/describe}</p>
	<pre>{$action/xquery}</pre>
	</div>

A slight addition to the original render function makes this easy. Below shows the the full TXQ module.

	(:~
	: A(nother) templating Engine for XQuery (BaseX 7.5 specific)
	: specials:
	: partial(file,name,sequence)
	:
	: @author andy bunce
	: @since sept 2012
	:)

	module namespace txq = 'apb.txq';
	declare default function namespace 'apb.txq';
	import module namespace xquery = "http://basex.org/modules/xquery";

	(:~
	: template function
	: @param template url to fill
	: @param map name and value to apply
	: @return updated doc from map
	:)
	declare function render($template as xs:string,$map as map(*)){
	let $map:=map:new(($map,map{"partial":=partial(?,?,?,$map,$template)}))
	return xquery:invoke($template,$map)
	};

	(:~
	: template function with wrapping layout
	: @param layout
	: @return updated doc from map
	:)
	declare function render($template as xs:string,$map as map(*),$layout as xs:string){
	let $content:=render($template,$map)
	let $map:=map:new(($map,map{"body":=$content}))
	return render($layout,$map)
	};



	(:~
	: partial template function: evaluate part for each value in sequence
	: @return updated doc from map
	:)
	declare function partial($part as xs:string,$name,$seq,$map,$base){
	for $s in $seq
	let $map:=map:new(($map,map{$name:=$s}))
	return render(fn:resolve-uri($part,$base),$map)
	};

Software updates

NAS updates

RAIDiator on readynas to 4.1.10 need to add index.xml to /etc/frontview/apache/httpd.conf
RAIDiator on velvet to 4.2.22

Hoping 4.2.22 will fix the Readynas pro locking up after a couple of weeks.

PaaS

My openshift BaseX instances seem broken by their upgrades. Version rhc 1.0.4 is giving permission denied for server. this?

Gadgets: tl-wr703n

I bought one of these : totocity Chinese Handy Wi-Fi Wireless Router 150M Wifi Wi-Fi for USB 3G LAN WAN Converter with the idea of creating a MIFI wireless network to use with my tablet.

To be honest I thought it had a 3G modem, but in fact it can only make use of one via USB - never mind I have a ZTE modem and it looks like a fun device.
£21 for a tiny UNIX server with LAN + WIFI. More information here. Hardware hacks here

Step 1

"I wouldn't call this a router for the average home user."

I replaced the Chinese interface with open-wrt see instructions at Installing OpenWrt on the TL-WR703N not too hard really.

http://wiki.openwrt.org/toh/tp-link/tl-wr703n

Step 2

Getting the modem to work..

install packages :

kmod-usb2,
kmod-usb-option,
comgt,
usb-modeswitch,
usb-modeswitch-data

to be continued...the boot log

Drawing trees with XQuery and SVG

Looking for a simple way to draw tree structures, I came across this old xml.com article Automated Tree Drawing: XSLT and SVG by Jirka Kosek. This uses some EXSLT extensions. I am sure it could have been rewritten in XSLT2 but I thought it would be interesting to try it in XQuery ( and add a RESTXQ web interface). Demo and source.

Upgrading to dojo 1.7

Starting to upgrade the places website to dojo 1.7 migration-17
And trying to get to grips with the build system

Issues

dojox.widget.Calendar not AMD compatible
Require declare vs define

Web based code editors

Looking for a nice web based code edit component. I wanted XQuery and Sparql in addition to the usual suspects. The choice seems to be between Codemirror and Ace.

Codemirror supports both Sparql and XQuery out of the box.

Ace has very nice XQuery support initially developed for the eXide feature of eXist by Wolfgang Meier and then enhanced, and pushed back to the main Ace project, by William Candillon. Ace currently has no official Sparql mode, but I spotted Callimachus has the code for a slightly earlier Ace release.

For me the deciding factor is that ACE is built with AMD support, whereas Codemirror is not. There is a project to convert/wrap Codemirror for use with Dojo, which means using AMD, but it looks like a lot of work.
Related projects to watch: Treehugger and Dojo Widget for Ace

Marklogic 5

I picked up a MarkLogic USB drive with 5.0.2 at XML Prague 2012. I installed this on Ubuntu but I wanted to get it to run on my Readynas Pro 2. This wish resulted in a factory reset on my first try, while attempting to install alien.

Older and wiser I tried again using chroot with a Debian Sarge image. The source file from the USB was MarkLogic-5.0-2.i686.rpm. Instructions based on
http://developer.marklogic.com/download#comment-354202122

To install

After doing debootstrap to create /c/home/squeeze

chroot /c/home/squeeze 

sudo apt-get install alien
sudo alien --to-deb --verbose MarkLogic-5.0-2.i686.rpm
sudo dpkg -i marklogic_5.0-3_i386.deb

To run

mount proc /c/home/squeeze/proc/  -t proc
cp /etc/resolv.conf /c/home/squeeze/etc
cp /etc/hosts /c/home/squeeze/etc
chroot /c/home/squeeze
/etc/init.d/MarkLogic start

Virtualised Debian Squeeze on Readynas

After burning my Readynas through reckless upgrades I noticed some comments referencing chroot. This promised a way to have an up to date system and protection from rogue packaging problems.

Installing new Debian systems with debootstrap

root@velvet:/# cat /etc/debian_version
4.0

apt-get install debootstrap

cd /usr/share/debootstrap/scripts
ln -s lenny squeeze
debootstrap squeeze /c/home/squeeze

chroot /c/home/squeeze



root@velvet:/# cat /etc/debian_version
6.0.4

All very simple and very nice.

Readynas recovery

Trying to install Alien on my Readynas Pro 2, which runs the ancient Debian etch release, corrupted the os and needed a rebuild of my environment. This entry documents the recovery steps.

Java

Java install seems to have got a lot more complicated since the initial install a year or so back. I could not find an apt package. So manual download from:

to /opt/java/jre1.7.0_04, then try to patch up a bit...

update-alternatives --install "/usr/bin/java" "java" "/opt/java/jre1.7.0_04/bin/java" 1 
update-alternatives --set java /opt/java/jre1.7.0_04/bin/java

(Some related stuff, did not use options or more)

listman

The BaseX 7.2.1 release brings together a couple of interesting features that I wanted to check out. A RESTXQ implementation based on Adam Retter's XML Prague 2012 paper, and an approach to XQuery Update that allows a return value as well as persisting XML changes. It seemed like fun to try these with Alain Couthures XSLTForms

The result..

The code is in 3 main XQuery modules

listman-rest.xqm The web application
web.xqm A simple templating system
edit.xqm handles the XForms editing

The code is in bitbucket See readme.md for installation instructions. The BaseX RestXQ implementation is here

XQuery parser in Javascript performance

"even more scary is how lightning fast the exact same program is in javascript... "
@wcandillon

What are the numbers?

Gunther Rademacher's REX parser generator can target several languages including Javascript.

The Javascript output is designed for jrunscript. To see what it expects use the option:
Main program=simple
jrunscript did not work for me, nor did Rhino, probably due to my lack of familiarity with these tools.
I wanted to run using Node.js and this required a few changes to the javascript

changing the writeOutput function to capture the result
setting the module exportsmodule.exports = xquery30

The node main module is:

var Xq=require("./xq3.js");
var out=[];
var parser=new Xq("2+3",out);
parser.parse_XQuery();
console.log(out.join(""));

The numbers:

time node app.js
real 0m0.278s
user 0m0.212s
sys 0m0.020s

No doubt the c++ is faster. Perhaps the winner is EBNF.

Payment service

Gumroad is a new payment service aimed at digital goods sales that works in over 190 countries. As someone who builds small web applications with subscription fees, I can honestly say that receiving payments is the least fun part of development. It’s fun getting paid, but dealing with payment provider APIs can be stressful to say the least. So I read with interest when Vadim Demedes sent us his Node Gumroad client (License: MIT, GitHub: vdemedes / node-gumroad, npm: gumroad).

How to tag classical mp3 files

Basic Guidelines

The Artist should contain just the composer not the performer. For details, see below and ClassicalReleaseArtistStyle.
The ReleaseTitle should include the title of the release followed by the major performer (i.e. the name of orchestra or quartet) inside parenthesis. For details, see below and ClassicalReleaseTitleStyle
The TrackTitle should contain the overall work (name of the symphony etc.) followed by ':' and then the actual name of that movement. For details, see below and ClassicalTrackTitleStyle
Convert the release to a VariousArtistsRelease if it contains works by more than one composer (see ConvertReleaseToMultipleArtistsEdit and ClassicalReleaseArtistStyle).
