Everyone has moved to using web-forums or replying to blog postings.
It's a sad day for email-driven lists. Especially sad since the advent
of being able to get/send email on just about any cellphone with the
Gmail mobile app. Lists should be growing instead of shrinking.

A friend just pointed me to the very active JavaScript IRC channel on
Freenode.  Sign on to chat.us.freenode.net and join the ##javascript
room.

My handle on there is n_s, feel free to say hi :)

Also, the comp.lang.javascript news group is still alive.  You can
access it on the web through Google groups:

Speaking just for myself, I haven't gone anywhere.  This is still the 
best source of interactive JavaScript advice I know of.  It would be 
interesting to learn if the membership of this list has shrunk, or 
merely the activity of late.

I haven't been posting here myself much this past year because I've 
had twin babies on my hands; 139% of my time is taken up with 
fathering and earning a living; luxury activities such as sleeping 
will have to wait.  I've unsubscribed (temporarily, I assume) from 
all dozen or so listserves I've belonged to -- except this one.  And 
JavaScript is hardly my main interest.

I think one reason I like this list is that the traffic is fairly 
light and the quality high.  My main PHP list has dozens of posts an 
hour and many of them are dross, either off-topic, redundant, or 
trivially argumentative.  It was a chore to sift through it in the 
best of times, impossible now.

One thing I miss here in particular is solving regular expression 
problems and the contributions thereto by Shawn Milo.

Regards,

Paul

I've been working with regex using a lamba expression for replacement
values to parse mergecodes from a CMS-like html template.  That the
lamba expression is also a closure over a particular node in a
linked/tree of nodes make for some interesting code.  Q: "You can do
all that in one statement?"  A: "Yup."

Sounds fascinating!
http://en.wikipedia.org/wiki/Lambda_calculus

There's an ECMAScript example here:
http://en.wikipedia.org/wiki/Closure_(computer_science)#Closures_and_first-class_functions

and this:

The New Replace Method's Lambda Expression
http://www.webreference.com/js/column26/lambda.html

Can you show us some examples using JavaScript that you've written 
with an explanation of what they do?

Cheers,
Paul

assumption(s):
template = "from: <<fromUser>>  to: <<toUser>> subject: <<subject>>";
N = { fromUser: "MikeD"
        ,toUser: "Paul"
        ,subject: "example"
        }

/* iterating through tree of messaging nodes */
while( N ){
/* create a function that closes over the current object (in this case N)
    and returns a function for use in a regex .replace() operation */
var replacer = function( oRef ){
  return function(str,p1,p2,offset,s){ return oRef[ p1 ]; };
  };
	
/* take the template, find each occurrence of a "mergecode"
and pass the mergecode found to the function
that is returned by giving the N object to the "replacer" function */
var rendered = template.replace(
   /(?:<<)([^>]*)(?:>>)/gi
  ,replacer(N)
  );

// do something now with the string in 'rendered'
// [ next N... ]
} /* end: while(N) */

In a previous project I first used .match() to get a list of
mergecodes, then iterated through the matches and made a global
replacement for each match.  That strategy may have been more
readable, but conceptually would perform worse as the number of
mergecodes and the size of the template increases.  For this case, I
already had a complex node tree in memory anyway.  This example uses a
much simpler template.  I'm also working on implementing a method to
execute functions of the node object for multivalued properties (like
multiple "To:" on an email) - so the template mergecode can contain a
function reference rather than a simple property reference.

While researching this solution (chatting with [freenode] ##javascript
IRC channel) I thought this technique might be a slick way to
implement an i18n character replacement - all it would require is an
object to act as an index of character mappings, and a regex to find
index keys to lookup.  Of course, I haven't implemented that yet so I
have no idea what devil-in-the-details would be encountered.

Comments?  Questions?  (other than "Are you crazy?" as both a comment
and rhetorical question)

Wasn't it IBM who scrapped a plan to switch their desktops to a cheaper
alternative when it became clear bits of their Intranet (written years
earlier when they thought they'd use Windows forever) depended on IE and
rewriting everything after the fact would inflate the cost dramatically?
(Hint, hint).

Use a library (like YUI or JQuery) to attach your events - they do all
the heavy lifting to normalise between browsers.

Generate the function using a closure.

	with semi-transparency support
Message-ID: <4909BC3D.8090808@gmail.com>

http://mediabeez.ws/mediaBeez/permalink.php?tag=visCanvasLoaderGraphic

This the second opensource plugin that I release; a loader icon capable 
of displaying colorfull yet semi-transparent animated graphics. It's 
simple to use and design for..

I'll admit right now that there are still some issues in IE, like 
activeX warnings in some cases, but i hope that over time those can be 
fixed and updated too..

Comments and bug-notices are very welcome, either on the list or  via 
the comments-button (top-left on the page).
