gmane.lisp.scheme.hop

scheme to javascript

Joop Ringelberg — 2012-05-25T20:09:40

Hello Hop-builders and users,

I wondered: is it possible to use the hop shell to compile a scheme program
file to a javascript program file, i.e. is there a command to do so?

Thank you in advance,

Joop Ringelberg

Plus:
    3. click on the hop icon (in the middle of your browser)
       that appears after step 2.

Hi Sven,

You are right. This is a bug I have introduced when fixing the HTML compliance
problem. This one is now solved.

Hum. I not able to reproduce that one. Could you be more precise? If I 
understand correctly, you have:

  1- browsed http://localhost:8080/hop/doc
  2- clicked on the small yellow icon on the bottom left

Nothing else? It might be that this is an "old" problem already solved. 
I'm not sure...

Dear hop team.

I installed the latest hop server - worked fine!

Some problems:

If I click on the "doc" icon and then on any entry,
I get a hop window showing:
"hop Error: hop_notepad_select -- Can't find pad: doc-api"

If I select the hop dashboard in the lower left corner
and then click on the hop icon, a hop window reports:
"deprecated (add-event-listener! "g2831" "server"...)"

Dear Vincent Prunet,


we have chosen HOP as the programming environment of choice
for providing a question answering system on the web, see
http://www.loganswer.de/
HOP only serves as a frontend to this system (logging,
registering users and sending them emails, accepting
questions of users and showing computed answers to these
questions). The main work is done on other computers
running servers accessed by plain socket communication
and a proprietory protocol. These programs have been
written in bigloo scheme, so using a similar language
(hop) for implementing the web-based user interface
was a straightforward choice.
What I like about hop:
- similar language for developing client logic and
  server logic
- can develop client and server logic in one file,
  so that interaction of client and server is easy
  to see from the source code
- multithreading support (threads, mutexes,...)
- integration of sqlite (easy to develop web-based applications
  that need to store data persistently)
- ease of integrating

Hi Sven,

Not yet because we are working with out sysadmins in a new solution
where hop.inria.fr will be a virtual machine.

For now, you can download the hop-2.3.0.tar.gz file, install it locally
and access the a local version of the hop home page with

  http://localhost:8080/hop/home

cheers,

Great news!
The remaining errors seem to be marginal and your reasons for

Is there an instance of the fixed hop server running somewhere?

Thanks Manuel!

Hi Sven,

I have significantly improved the HTML compliance. Now the Home web page
shows only 5 errors:

  Line 25, Column 5465: there is no attribute "ONERROR"
  Line 25, Column 5816: there is no attribute "DATA-HSS-TAG"
  Line 25, Column 5880: there is no attribute "DATA-HSS-TAG"
  Line 25, Column 5948: there is no attribute "DATA-HSS-TAG"
  Line 25, Column 6132: there is no attribute "DATA-HSS-TAG"

The DATA-HSS-TAG are illegal but operational with HTML4 browsers and
legal with HTML5. I'm reluctant to switch from html4 to html5 for the
Hop home page because I think it would yield old browsers to no longer
to render the page correctly.

Same thing on the first error, the illegal ONERROR attribute. That
attribute is exclusively used by IE. It is harmless with other browsers
that don't use it.  We could remove that attribute to improve compliance
but this would degrade portability! I think this is one of the any
examples of HTML compliance degrading HTML portability. I'm not enough
an HTML expert to find com

Study on HOP usage

2012-05-09T20:25:34

Dear HOP list subscriber,

Here at Inria, we are conducting a study about what you, as a user, are doing
with HOP and why you have selected HOP to perform such tasks (of course, we are
also interested to know if you think you made a sensible choice, we hope so :-)
Your feedback will help us advocate for HOP, and drive future extensions or
applications.
So please post a message on the list, or send me a private email by the end of
next week, on May 18th. Provided that we get a number of answers, we will post
a summary report on the following week. 
Privacy policy: Unless otherwise stated in your message, answers mailed
directly to me will be anonymized in the summary report.

That's definitively a good reason for improving the compliance.

Yes, really? I will check as soon as the server is up.

Thanks again Sven for all your suggestions.

Cheers,

Sven Hartrumpf — 2012-05-09T18:18:16


Yes.

One concern is ranking in search engines: popular search engines
downrank sites that show many HTML errors.

And: If your site comes back, you will see in the w3c validator
output that most defects seem very easy to be fixed because they
come from the main elements in HTML generation (like <IGM>) in hop.

Re: Last chance to test hop-2.3.0

and a last word about HTML validation...

I don't think HTML validation represents a guaranty of any kind that the
web page is portable. In my experience, with modern browsers, that is
all browsers expect IE<7) 99% of the incompatibility issues come from
JavaScript, not from HTML nor CSS. The two critical points being:

  1- When are JavaScript expressions evaluated.

  2- When a new HTML fragment containing a SCRIPT is inserted, is that SCRIPT
     executed or not.

Re: Last chance to test hop-2.3.0

2012-05-09T15:45:40

Hi Sven,

Okay. I think we could have a discussion here. I think there are two reasons
for Hop HTML code not be compliant. 

  1- Hop let programmers generate arbitrary HTML code. Hence, it is possible
     to generate non compliant code. Is that a problem for Hop? My point of
     view is that it not. 

  2- Hop uses some tricks that have now been integrated in HTML5 (in particular
     the data-XXX attributes). We have not totally replaced uncompliant 
     attributes with compliant ones but we will in a close future. I don't see
     this as a real problem.

All that said, we should probably works harder to make the main hop page
W3C compliant. I don't feel a strong incentive for doing that now but I
agree that it would better.

Argg. We have a hardware failure on the ethernet card of the machine. Until
this morning the machine was up. It seems now down again :-( I won't be
able to check what's going on this afternoon. I will try my best to
fix that problem tomorrow morning.

Sorry for the delay.

Dear Friends,

It is now time to release hop-2.3.0, the first stable version of the 2.3.x
branch. The last test version is currently available on the Hop ftp repository.
Unless someone spots a sever problem in the coming days, that version will
be officially release by Friday noon.

Thanks again for your last tests.

Hi,

I just want to inform you that hop.inria.fr in currently unavailable due

bring it back on Monday.

Thanks a lot, I have missed that. The site is now up.

I'm still preparing 2.3.0. I hope it will be ready by the end of the week.

Ah sorry. I have misunderstood your mail. I have not check the Mercurial
server. I have checked the main Hop server. The problem should be
fixed now.

Perfect.
