Re: [Pharo-users] A Spec widget to hold non-editable multi-lines text?

Hi,

Thank you it works as expected :) Maybe this should be documented in the
class comment of TextInputFieldModel?

Re: [Pharo-users] MetaLink invocation with method returned value

[Yuriy Tymchuk]

As far as I know return values for methods are not yet implemented. I’ve talked 
with Marcus, it’s planned but not the top priority. For now you can all links 
to the return nodes of a method.

[Pharo-users] MetaLink invocation with method returned value

[Alain Rastoul]

Hi,

I would like to trace returned values with MetaLink, but didn't found 
the correct #arguments: parameter.
Here in my example  I would like to call aMethodCall:returned: with the 
return value of aMethodCall:

(the method on which the link is installed)


(MyObject>>#aMethodCall:) ast
link: (MetaLink new
metaObject: myObject;
control: #after;
selector: #aMethodCall:returned: ;
arguments: #( arguments object)).

object is myObject not the returned value, value does not work, and I 
didn't found any one working.


Does anyone know the correct invocation and can help me ?

Many thanks


regards,

Alain

[Pharo-users] short spotter demos

Thanks. Indeed, I agree with you. In fact, this is what we did, and then I was

was a little experiment.

The thing is that we do not want to disturb people, but we need the feedback to 
improve fast. So, right now it looks like the only real way to get feedback is 
to push the changes. This has the tendency to create some annoyance, but we are

Indeed, it is now in the image.

Unfortunately, there was no feedback :(. I will do it better next time. I just 
thought that given the urgency with which issues were reported, people would 
have been more eager to test, so I hurried up :).

Hi!

I do not get this. Relying on the baseline is not enough?

Roassal is very simply packaged. Only 4 packages: Roassal, Trachel, 
Roassal2Spec, Roassal2GT. It is very unlikely that this list of package will 
grow (not until we have a Git integration at least). You can make your 
configuration directly point to these packages no?

Alexandre

Great call and initiative.

I would like see

- get the graphViz algo finished (even if not fully working) Anne

but it would be a real game changer.

Yes, I generate .dot file that describes the nodes I want the layout for
(that includes the dimensions of it), and then the .dot file is passed to
GraphViz… from there I parse the generated SVG file (they can also output
other formats like txt, or xml) and move the Roassal nodes.

GraphViz is good enough for generic graphs, but OGDF is well-founded and
much more powerful layouting library. However C++ coding is required if one
wants to use it.

how does that work? does it ask graphviz for the position of the nodes and then
recreate that in roassal?

given that there is no comparable layout in roassal available this would
certainly be useful.

this would work the same as with graphviz as an additional dependency on ogdf, 
right?

Do you have a screenshot showing the issue?

Yes please, some screenshots would help

Unfortunately making real graph layouts is really hard issue… I've wrote my
bachelor thesis about this and didn't get very far; it's bit of a nightmare
if you don't have good foundations. :'(

In any case, I wrote a simpler layout delegator in Roassal that delegates
the layouting to graphviz and it works reasonably well, so I could probably
add it to Roassal (you however need graphviz installed and it would add
another dependency to Roassal, which I'm not so keen on).

Maybe also OGDF (http://ogdf.net/doku.php) could be used if you are ok with
GPL… they have their own graph format so there could be some interaction.

Dear community,

As you may have seen, Roassal has entered a stabilization phase. The book 
AgileVisualization.com will soon be released. After its release, Roassal will 
go over a new development phase. In order to prepare it, I am asking this 
question:

What are the 3 aspects you would like to see improved in Roassal?

You can answer publicly or by sending private messages.

Kind regards,
Alexandre
