Text Indentation in Pharo editor
by Torsten Bergmann Dec. 11, 2017

Dec. 11, 2017

Hi, in most code editors I know one can select a (multiline) block of code/text and then hit TAB to indent and move it from the position to the right side. Using SHIFT+TAB one can move it back to the left. In Pharo the selected text unfortunately is always deleted instead of moved/indented when hitting TAB. Is such an editor mode or special key combination available? If not could this easily be brought into the current text/code editor(s) in Pharo 7? Or will a possible upcoming Bloc text/code editor support such behavior? This would be really nice to have and move Pharo editor away from being like Notepad. Because editors in Eclipse, NetBeans, VS, Brackets, Atom, Notepad++ all support this TAB Indentation out of the box. ;) Thanks T.

About margin and rectangle
by Stephane Ducasse Dec. 10, 2017

Dec. 10, 2017

Hi While harvesting the old change of Henrik on margins and the idea that Rectangle should not be used to express margins. I looked at expandBy: comment In fact I would like to make sure that that no rectangle is passed as argument and that we can deprecate asMargin from the Rectangle class (we can keep it but I would like to identify the callers). expandBy: delta "Answer a Rectangle that is outset from the receiver by delta. delta is a Rectangle, Point, or scalar." ^ delta asMargin expandRectangle: self So looked at all the senders of expandBy: and they look ok. I imagine that I should do the same for extendBy: Stef

[ann] gtmondrian
by Tudor Girba Dec. 10, 2017

Dec. 10, 2017

Hi, We are happy to announce GT Mondrian, a graph visualization engine built on top of Bloc. It is similar to the original Mondrian and the Mondrian from Roassal, but it is different in that it is built directly out of Bloc elements. This is interesting because it allows us to combine typical widgets with visualizations. The other interesting thing about it is that it validates the design of Bloc: right now, the implementation has 509 lines of code (excluding graph-specific layouts). The goal is to make visualization a first class citizen and an integral part of the IDE. The key ingredient that made this happen is that Bloc can now treat graph layouts, such as tree or force based, behave under the same rules as typical widget layouts, such as grid or flow. The challenge comes from the fact that a graph layout depends on the notion of edges between elements, and we did not want to have elements know about edges in the core of Bloc. The solution was to split the typical edge implementation in graph visualization libraries into two distinct concepts: â¢ Line is an element that draws the connections. â¢ Edge defines constraints imposed by connections between elements. Thus, edges form constraints, and constraints are what layouts deal with. That is one reason why elements in bloc have the ability of defining layout-specific constraints. Using this, we can nicely define edges between elements as a plugin to Bloc, but still be able to connect arbitrary elements. What's more, it turns out that we need constraints for other layouts as well. For example, an element in a grid layout might specify the span. The API of GT Mondrian is similar to the one from Roassal, but there are a few differences as well. These are described in the Pillar documentation available in the GitHub repo. The best way to experience GT Mondrian and its documentation is to load the GToolkit as described here: https://github.com/feenkcom/gtoolkit If you download the GT code through Iceberg, the documentation can be experienced live by inspecting: './pharo-local/iceberg/feenkcom/gtoolkit-visualizer/doc/mondrian/index.pillar' asFileReference Cheers, The feenk team -- www.tudorgirba.com www.feenk.com "Quality cannot be an afterthought."

Re: [Pharo-dev] Two tables that share the same data source!?
by Aliaksei Syrel Dec. 9, 2017

Hello Elhamer, Do you have an idea when it might be useful to have two lists representing the same datasource? We have this feature in bloc (see video in attachment) but I didn't encounter a real-life use-case yet...

metalink injection into closures ?
by Ben Coman Dec. 9, 2017

Dec. 9, 2017

When we execute this... counter "Greeter new counter" | count | count := 0. [100 timesRepeat: [count := count + 1. self inform: count + 1 printString. 2 seconds wait]] forkNamed: 'Count de Money' and in the dubgger correct and save the code we normally get the message... "Method for block not found on stack, can't edit and continue." and I wonder if anything with Metalinks would facilitate inject the corrected bytecode into the Process so that it oculd continue. cheers -ben

About margin and 16969
by Stephane Ducasse Dec. 9, 2017

Dec. 9, 2017

Hi henrik I started to rescue your fix on wrong use of rectangle. Then I noticed that you change the height of a margin. We defined it as height ^ self bottom + self top Since we were considering that the height of a margin is the total amount of space around. and you as height ^ self bottom - self top Do you have a strong reason for that?

Release: Conveniently browse, deactivate and reactivate halts and breakpoints with the HaltManager
by Thomas Dupriez Dec. 9, 2017

Dec. 9, 2017

Hello, I have developed a package to assist developers managing their halts and breakpoints: HaltManager. HaltManager provides a window showing all the breakpoints and halt messages of the system, and allows one to toggle them on/off with a simple click. Halt messages can also be toggled via source code rewriting. The deactivation/reactivation feature is available in all code browsers, not only in the HaltManager window. It is available here, with installation instructions and pictures: https://github.com/dupriezt/HaltManager Feedback welcome. Cheers, Thomas Dupriez
