Where is "recover lost changes"?
by Andreas Brodbeck Jan. 5, 2018

Jan. 5, 2018

Hi all In the newest Pharo 6.1 I miss a feature from the older Pharos "recover lost changes", which showed me all code changes after the image crashed. I am aware of the new Epicea, which is great, but I can't really get it to show me only those changes since the last image save. How can I get those changes? Cheers, Andreas -- Andreas Brodbeck www.mindclue.ch

Removing contents-changed marker from Rubric on save
by Evan Donahue Jan. 5, 2018

Jan. 5, 2018

Currently, if you add a "composite text" view using gtInspector, the editor lets you use ctrl+s to save changes to the local inspector. However, if you intercept ctrl+s to implement an actual save function, as FileReference does, the text editor no longer knows to remove the contents-changed indicator. You can see this in the current FileReference inspector: f := FileSystem disk / 'tmp' / 'filerefinspectortest.txt'. f writeStreamDo: [ :s | s nextPutAll: 'test data' ]. f inspect. "Change the data and hit ctrl+s. The contents-changed indicator is still there." f inspect. "If you inspect again, you will see that the contents have indeed been saved to disk." How would I change code like the FileReference >> gtInspectorContentsIn: code to make the content-changed indicator work properly? Who is in charge of that indicator and how do I tell them to turn it off? Thanks, Evan

Solver for the Stable Marriage problem in Pharo
by Julien Jan. 4, 2018

Jan. 4, 2018

Hello, Continuing to announce what I have. Some time ago I implemented a solver for the Stable Marriage problem [1] in Pharo [2]. Basically, in the stable marriage problem, you have two list of n element: a list of men and a list of women. Each person rank people of the other gender according to its preferences. The stable marriage algorithm find the best matches between men and women according to all rankings. It can be installed using: Metacello new baseline: 'StableMarriage'; repository: 'github://juliendelplanque/StableMarriage/repository'; load Regards, Julien --- Julien Delplanque Doctorant Ã lâUniversitÃ© de Lille 1 http://juliendelplanque.be/phd.html Equipe Rmod, Inria BÃ¢timent B 40, avenue Halley 59650 Villeneuve d'Ascq NumÃ©ro de tÃ©lÃ©phone: +333 59 35 86 40

Releasing to Catalog
by Evan Donahue Jan. 3, 2018

Jan. 3, 2018

I'm getting close to figuring out how to put something in the catalog, but I have run into a slight problem. I am following this tutorial: http://blog.yuriy.tymch.uk/2015/07/pharo-and-github-versioning-revision-2.h… It has gotten me through making a BaselineOf and putting it on github. That part works. The part that doesn't yet work is the ConfigurationOf I made exclusively for the Pharo catalog. I can see my project in the catalog browser, and download the config, but I can't "Install stable version" through the catalog browser. However, I can manually use the ConfigurationOf to load the project once it is in my image. Does anyone know how to diagnose this? It may have to do with the fact that my ConfigurationOf doesn't have any baselines, because I understood the tutorial to suggest that my BaselineOf could fulfil that function, but perhaps I misunderstood. The project is called "Cons" and its ConfigurationOf is here: https://github.com/apocalypsemystic/Cons/tree/master/ConfigurationOfCons.pa… Thanks, Evan

Hi Since for some experiences in moose we needed more named colors I started to gather together some old extensions and I cleaned the implementation. Now we have emacs colors and XKCD i.e around 1600 named colors. Gofer new smalltalkhubUser: 'StephaneDucasse' project: 'Colors'; package: 'MoreColors'; load. Color initializeNames I would really like to see how we can model the notion of color palettes. Stef

[ANN] PoLYgon file format parser/model
by Julien Jan. 2, 2018

Jan. 2, 2018

Hello again, Last announcement for today. 1 year ago I created a PLY (PoLYgon file format [1] ) parser/model in Pharo [2] using PetitParser. I took some time to remove the dust it accumulated and to create a baseline so I announce it. To install it: Metacello new baseline: 'PLY'; repository: 'github://juliendelplanque/PLY/repository'; load. It has tests and an example of usage in the README. Regards, Julien Links: [1]: https://en.wikipedia.org/wiki/PLY_(file_format) <https://en.wikipedia.org/wiki/PLY_(file_format)> [2]: https://github.com/juliendelplanque/PLY <https://github.com/juliendelplanque/PLY> --- Julien Delplanque Doctorant Ã lâUniversitÃ© de Lille 1 http://juliendelplanque.be/phd.html Equipe Rmod, Inria BÃ¢timent B 40, avenue Halley 59650 Villeneuve d'Ascq NumÃ©ro de tÃ©lÃ©phone: +333 59 35 86 40

[ANN] Orientation
by Julien Jan. 2, 2018

Jan. 2, 2018

Hello, I developed a small framework to model orientation (north, east, south, west). It defines some common operations that can be done on such objects (turning, getting the opposite orientation, moving on n steps on a discrete grid from a given position following certain orientation, etcâ¦). Also, it supporte composed orientations (e.g. north-east). More details on GitHub [1]. To install it: Metacello new baseline: 'Orientation'; repository: 'github://juliendelplanque/Orientation/repository'; load This is not a lot but it is tested and I think it does its job well. So if you need to model orientation, consider to use it. :-) If any ideas of what I could add to this API, Iâm interested.
