workspace issue

Hi David.

You are using (a fresh) Squeak 5.2 #18232?

Can you share a screenshot of the issue (workspace + debugger)?

What are your favourite preferences you set up in a Squeak image?

Best,

Marcel

Hello,

I'm having an unusual problem with my workspaces. I'musing 

Squeak 5.2 on a windows machine.

If I enter an expression in a workspace  and then 'print it' all

works fine

However if I try to preform an action, e.g.

Transcript show: 'hello'

or

'x:= 1'

in the workspace and then 'do it' either by  

Alt -d  or by menu action.

I get an exception

Message not Understood Undefinedbject >># selectionInterval

The rot seems to be Parser>>variable

My hunch is that one of the methods was getting an ill-defied interval

i.e (lo to: hi) with lo >=hi,

but I have not been able to confirm this in all cases.

I haven't seen any similar reports, so I suspect its not a system issue.

Any thoughts on what I might be doing wrong?

thanks,

David

Hi David,

could you select the signature of the #correctVariable:interval: method and press <cmd>m to browse its implementation? Your screenshot reveals that your implementation of this method is not equal to that one Squeak 5.2 was delivered with. If you browse the implementation, you can see an annotation bar below the code. Check out whether the method is put into an extension category (that begins with an asterisk). Could you send us a screenshot of this browser window? I guess you installed any package that overrides this method.

Best,

Christoph

H Marcel,

My imageisn't #18232 it is #18229;here are the full details from About Squeak

Squeak5.2-18229-64bit-201810190412-Windows\djd-dev-64bit.image
Squeak5.2
latest update: #18229
Current Change Set: Unnamed
Image format 68021 (64 bit)

I attach a screenshot. Its a window shot rather than a squeak. Whilst I can take one  

I was unsure how to output a screenshot from within squeak itself .

Preferences. I'm unsure which might be relevant.

Compiler: allow underscore assignment/selectors; allow block argument assignment

Tools:uesUnified  Message Labels is set though I'm unclear that this is relevant

If you can narrow down to a category I can report all settings.

I don't have many change sets installed, the only relevant one might be the Whisker Browser,

Changing the subject line.

Can anyone provide status of MathMorphs and Morphic Wrappers on current
Squeak? Have there been any recent updates?

Edgar has included Morphic Wrappers in his FunSqueak5dot2alpha image, so
it certainly can be done:

  squeakros.org/FunSqueak5dot2alpha.zip

I don't think that Edgar plans to do further maintenance on this, so it
would be great if some other interested folks can help.

I see that the MathMorphs package got updated for 5.1 in 2014 (http://wiki.squeak.org/squeak/1195) *but* the latest version of MorphicWrappers pointed to still has that same version of the correctVariable:interval: method.

The less good news is that the method got massively refactored in 2009 and the prior version to that from 2005 was already very different to the copy in MorphicWrappers-edc.3 So we'd need to look at the full history and find the version just prior to 11/4/2000 to work out what change was intended and make whatever equivalent change to the current version.
