PlotMorph on Pharo 6.1

I downloaded 64bit Pharo from
<http://files.pharo.org/platform/Pharo6.1-64-mac.zip>

Started it and first thing opend Catalog Browser.
I searched for plot
Chose pLotMorph and chose Install Stable Version

I got an Information window saying There was an error trying to install
PlotMorph. Installation was cancelled.

So
1) Does PlotMorph work as it is in the SystemCatalog I assume so. So how
shoulkd I load it?
2) How can I see what the error actuially was
3) How can I actually capure the popup window to cut and paste the
error.

Mark,

Open a Transcript window before loading PlotMorph.
Which error message do you get there?

Re: PlotMorph on Pharo 6.1

Thanks for the report since I need PlotMorph too for a project.
What you see is the consequence of lack of validation of published
packages. This is years that I'm saying that I need someone to work on
that.
We got money from inria for Pavel to work on it but the bootstrap was
more important :).

To debug this:

Instead of installing the stable version, load the configuration.

Type shift-enter to open Spotter.
Type Plot and enter to find ConfigurationOfPlotMorph and browse it.
First take a look at method #stable to see what is defined there

stable: spec
<symbolicVersion: #'stable'>

spec for: #'pharo3.x' version: '1.0'.
spec for: #'pharo5.x' version: '1.0'.
spec for: #'pharo6.x' version: '1.0'.

That looks good, a stable version is defined for Pharo 6.
A stable version is missing for Pharo 7

Take a look at #version10:

version10: spec
<version: '1.0'>

spec package: 'PlotMorph' with: 'PlotMorph-StephaneDucasse.7'.

Hmm, that doesn't look good. That is not a complete Metacello spec.
It looks like the reference to the baseline is missing.

baseline10: spec
<version: '1.0-baseline'>
spec
for: #pharo
do: [
spec blessing: #baseline.
spec description: 'First Full Configuration'.
spec author: 'StephaneDucasse'.
spec timestamp: '29/12/2013 12:29'.
spec repository:
'http://www.smalltalkhub.com/PharoExtras/PlotMorph/main'.
spec package: 'PlotMorph' ].

Yep, there is the missing information.
So let's fix the version10. We can do it in place, as this can not have
worked. Otherwise we would have had to add a new version, and updated
the #stable.

In this case shouldm't the catalog only be added to if someone actually
takes an action to do this - then there is a chance the code would be
checked. Otherwise rollinmg over from one release to another just
accumulates junk.

OK I am now more confused as I see that suggestion does not work.

Looking for graphing packages I tried to load GraphET - which gives a
popup box

GraphET has not been marked as tested for Pharo6! Do you want to
continue (installation could fail)

Which seems to me to be a good feature,

But does imply some packages have been added and marked as tested
without being tested which does raise a large doubt in my mind as to
what is supposed to work and how can I trust parts of the system which
are marked as working.

Yes, that is the question I posed.
Assignment to block variables is prohibited now?

Re: PlotMorph on Pharo 6.1

Hi Mark,

In case you are not tied to PlotMorph, you can use Roassal for your drawing. Roassal supports Grapher, which is a resurrection of GraphET.

Documentation is available on:

http://agilevisualization.com/AgileVisualization/Grapher/0203-Grapher.html

Open Pharo 6, load Roassal using:

Gofer it
    smalltalkhubUser: 'ObjectProfile' project: 'Roassal2';
    configurationOf: 'Roassal2';
    loadDevelopment

And type in a playground:

b := RTGrapher new. ds := RTData new. ds noDot. ds points: (0 to: 3.1415 * 5 by: 0.01). ds y: #sin. ds x: #yourself. ds connectColor: (Color red alpha: 0.4). b add: ds. ds := RTData new. ds noDot. ds points: (0 to: 3.1415 * 5 by: 0.01). ds y: #cos. ds x: #yourself. ds connectColor: (Color blue alpha: 0.4). b add: ds. b

You will get:

Cheers,

Alexandre

Hi mark

live is chaotic here with two or three meetings in parallel, visitors,
and a lecture to finish
Now I tested. I took a Pharo 6.1 32 bits and loaded PlotMorph from the catalog
It load Stefaneggermont.8

Can you tell us how to reproduce your problem?
