Announcing JSqueak 2013 ALPHA

Hi Squeakers!
It has passed a long time from my last "squeakie"...hem..post on this
list :)
In this week I have started to work to on 2008's JSqueak source base.

JSqueak is a Java implementation of the Squeak Smalltalk virtual
machine first born in 2008 by Dan Ingalls.

You can take a peek look here to my fork:
https://github.com/daitangio/jsqueak
Original announce
http://lists.squeakfoundation.org/pipermail/squeak-dev/2008-June/129178.html

Please be patient because the code is still alpha quality and
unfinished. Every bug fix/unit test in the form of a Git Pull Request is
very appreciated :)

Give me your feedback!

Have you seen Potato?
http://www.hpi.uni-potsdam.de/hirschfeld/projects/potato/index.html
http://sourceforge.net/projects/potatovm/

Might be relevant for you. If I remember correctly, they improved JSqueak in a couple of places.

Best regards
Stefan

Seaside and/or SqueakSource question

I have been trying to figure out why our http://squeaksource.com server
displays the header "Squeak Development" at the top of the page, when
instead it is supposed to be "SqueakSource". I don't know a lot about
Seaside and web development, so maybe someone can point me to the obvious.

In this case the SqueakSource repository seems to be configured right,
and the actual html being sent to my browser looks right also. The header
section has has a title of "SqueakSource" exactly as expected:

<?xml version="1.0" encoding="iso-8859-1"?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<link rel="stylesheet" type="text/css" href="/@jhHhM7Zj_WTuhGPs"></link>
<link rel="alternate" type="application/rss+xml" title="SqueakSource" href="http://www.squeaksource.com/feed.rss"></link>
<link rel="shortcut icon" href="http://www.squeaksource.com/favicon.ico"></link>
<meta name="verify-v1" content="8GYvoqpWAQKRrqNkRtl24Eo/Phco14ibjhO4kDDXgDo="></meta>
<title>SqueakSource</title>
</head>

Somehow this ends up being displayed as "Squeak Development" on the title bar.
I am guessing that this might be somehow related to the CSS style sheet, but
I don't know where that comes from. Can someone point me in the right direction?

Thanks!
Dave

Hi Dave,

The thing ultimately responsible for displaying "Squeak Development" at the top of the squeaksource page is the SSGenericFrame's class instance variable named Logo, and you can change it with SSGenericFrame >> makeLogo:

I've discovered this via the following steps:

Opened up squeaksource.com with chrome, right-clicked on "Squeak Development" and selected "Inspect Element" from the context menu.

It shows that the responsible part for displaying "Squeak Development" in the html is the <div id="top">...</div> tag, and that

it has a background css property associated via its id: #top { ... background: url("/@k9MDSLXvXkJLBWh5") ... }

I've loaded SqueakSource-bf.1066 into an image, and looked for the string '#top'. This popped up the SSGenericFrame >> renderStyleTopOn: method. I've followed through the message sends, and finally arrived at the Logo class instance variable.

HTH,

Balazs

Hi Bal??zs,

Brilliant! Thank you. I feel like I'm debugging in a hall of mirrors, but
I think you have pointed me in the right direction.

I looks like the Logo class instance variable contains a cached MIMEDocument
that was created from a JPEG file that someone made with the "SqueakSource"
text and a nice blue graphic background. I do not have the original file, but
it looks like I can recreate it from the data stored in the MIMEDocument.

I will see if I can extract this graphic and use it to update the image on
the squeaksource.com server.

Much appreciated,
Dave

Re: Seaside and/or SqueakSource question

Hi Dave,

It seems that the original squeaksource logo is stored in the code in SSFrame class >> formLogo, and it is loaded in the class side initialize method.

Maybe it's enough to evaluate "SSFrame initialize" in the squeaksource server image to get back to the original logo.

Hi Bal??zs,

Thanks for this, I had not seen the #formLogo method.

I was able to correct the logo on the squeaksource.com site last night
by exporting the logo from the original squeaksource image, then using
it to initialize our current image on the squeak.org server.

It may be that the SqueakSource source code should be updated to
capture the two different header logos. I cannot check this right now
but I will follow up on it later.

For the record in case others are following this, I am attaching a
copy of the logo image (SSPageHeaderBytes.jpg) as well as the workspace
(Update the header logo.text) that I used to update the running image
last night. I created SSPageHeaderBytes.jpg file by writing out the
contents of the logo from the old (SCG) squeaksource.com image.

Thanks again for your help!

Dave
