error from hop wizard

Hi all.

I am trying to use hop and bigloo from 2012-01-18.
Installation went smoothly.

Then, I try to setup hop as follows:
1.
start hop as a normal user:
> hop -g --repl

2.
fire up a browser (Konqueror 4.7.2):
> konqueror http://localhost:8080

3.
I enter the sections for admin, user, and guest (3 users in total).
When I press "Save", the browser presents the following server error:

localhost:8080
path:   /hop/wizard/save
Hop server stack:
*** ERROR:wizard/save:
Wrong number of arguments -- (wizard/save)
    1. &pool-scheduler1756
Hop client stack:
(hop_default_failure ...)
/usr/local/lib/hop/2.3.0/weblets/wizard/wizard.hop <at> 2261, (save-accounts ...)
(onclick ...)

Any ideas?

Sorry for the late reply. I have just realized that I have fixed Hop but
I have forgotten to let you know about that correction. I agree with you.

deployment of webpages

Hi can anyone jump start me to the deployment process of hop compiled webpages?
I'm going through the tutorials but I have yet to grasp how easy it is
to set up a server hosting hop webpages.

hop 2.2.1 cannot find libhop_es-2.2.1.so

I've checked for libhop_es-2.2.1.so,
it is inside /usr/local/lib/ so i couldn't understand why it has
problem running.

This is what I get when I run hop.
hop: error while loading shared libraries: libhop_es-2.2.1.so: cannot
open shared object file: No such file or directory

my configure make install didn't complained about anything.

error with remove-event-listener!

Hello,

I am getting the following error in my browser when I click the
"Unsubscribe" button:

hop.js:6469 TypeError: 'undefined' is not an object (evaluating
'hop_servevt_proxy.httpreq.abort')

Is this a bug? Or am I doing something wrong?

(define-service (main)
  (<HTML>
   (<BODY>
     ~(define handler (lambda (h) (alert (event-value h))))
     (<BUTTON>
      :onclick ~(add-event-listener! "topic" "server"
                                     handler
                                     #f)
      "Subscribe")

     (<BUTTON>
      :onclick ~(remove-event-listener! "topic" "server"
                                        handler
                                        #f)

Changing hop/ part in URLs

Hi all.

Is there a simple way to change the "hop/" part of URLs
served by a hop server to some other string?

Ciao
Sven

hop-2.3.0-pre1

Hop-2.3.0-pre1 is now available. 

This is the first of the new branch. It contains many changes but most of
them are transparent and most hop-2.2.x programs should still work with the
new branch.

Please report any problem or comment to the mailing list.

Sincerely,

hop problem

Dear Manual,

  I am trying the latest hop-2.2.1 with the latest bigloo 3.7a-2 with
gcc32 (IA32) on x86_64 machine. Here is what I get if I browse to
http://localhost:8080/hop/hz.

Hop server stack: 
*** ERROR:string->obj:

    1. \ <at> hz-db-init!
    2. hz-db-init!
    3. \ <at> toplevel
    4. &pool-scheduler1713

Is this a problem with my installation? Any ideas?

Kind regards,

Before considering using Skribe again (I will help if this is really
what you want to do), may I suggest you to have a look at HopTeX? Hoptex
shares many similarities with Skribe but I think it is really superior
to Skribe. It's syntax is more pleasant and customizing the TeX and HTML
output is significantly easier. Lastly, it is more flexible. I have
written a short paper describing HopTeC, please find it enclosed here:

To let you have a look at what it looks like to write a paper with HopTeX, here
is the source code of that paper:
