Analysis/Visualizations of DBs
by Torsten Bergmann Oct. 3, 2015

Oct. 3, 2015

Hi, we have many nice analysis and visualizations tools available (Moose, Roassal, ViDi, ...) Often it is focused on development or code. Also we have refactoring tools. What would be cool would be to have some tool for doing this on (relational) databases and included data: - visualize databases (tables, data clusters, number of columns, ...) - analyze tables on satisfying some (external) business constraints and consistency rules - refactoring of databases (moving, migrating colums, ...) - easy building reports/visualizations of included data (extract, query, filter, ...) What I think of is a tool where (after connecting to a possibly unknown database) you can easily get/build an overview on the design, quality and data of the database (similar to what Moose, ViDi does for code). Is there any research, projects, ... for data mining already in Pharo? I guess this could make up a great toolset with Pharo as a base and make it more known because in the software business relational databases play a big role. Any takers for the next Pharo success story? ;) Bye T.

Spec LabelModel's #font: and other styles
by Peter UhnÃ¡k Oct. 3, 2015

Oct. 3, 2015

Does it make sense to be able to specify font and similar at Spec-level? And not just font, also the size, color, or emphasis (which currently only emphasis is supported). >From one perspective it's handy, because I can change it at a whim, however I wonder whether this shouldn't be responsibility of some styler instead. Text as far as I know is capable of storing styled information. This would enable to outsource the style information to someone else (e.g. your stylesheet). However from practical perspective for the end user it would be extra work as it would add an indirection step. For TextModel that would be clearly better (because you might want to style different parts of text differently), however for LabelModel I'm not so sure. Any opinions? Thanks, Peter

GTInspector: add view tab for custom object
by Mark Rizun Oct. 2, 2015

Oct. 2, 2015

Hi everyone, I would like to extend GTInspector for custom object - add a roassal view tab. I found this kind of code to do this: gtInspectorViewIn: composite <gtInspectorPresentationOrder: 40> composite roassal2 title: 'View'; painting: [ :view | self viewOn: view ] The problem is, that I want to use a view that I already have, but not the one which is passed as an argument to block [ :view | self viewOn: view ]. It should be simple. Am I missing something?

Rubric events
by Miguel Campusano Oct. 2, 2015

Oct. 2, 2015

Hello, I'm working on modifying the styling of text by using RubTextSegmentMorph. The problem is that the text could be modified dynamically by selecting another text, so the styling must be modified. I want to use the announcements system of Rubric but something weird happens. When I subscribe to the announce RubTextUpdatedInModel of the RubScrolledTextMorph, the styling sometimes works, sometimes doesn't. What I noticed in the method RubScrolledTextMorph>>whenTextUpdatedInModel: the announcement is done before setting the text in the morph and if I change this to make the announcement after setting the text, everything works fine. So my question is: Is there something special to announcer the set of the text before actually setting it? Is it ok to change it? OR Is another way to do what I want to do? Bests, Miguel
