When to use Versionner and when to use Monticello
by Sergio Fedi May 2, 2015

May 2, 2015

Great, now that I saw these screencasts of Versionner (which I'm still trying to have a hang on) I would like to ask: When do we use Versionner and when do we use Monticello? Putting it in another way: What tasks are only possible through Monticello? What tasks you should be doing in Versionner?

inverting colors of athens(cairo)canvas
by Peter UhnÃ¡k May 1, 2015

May 1, 2015

Is it possible to invert the colors of a Athens Canvas? After some digging I found paintMode and paintTransform; however the former doesn't support such method (maybe some combination of xor and over?); and the former is only for some specific colors. I also tried changing Color>>asAthensPaintOn: ^ (Color white - self) alpha: (self alpha) "invert the color" and while this works nicely for most cases, it is overriding a library and _doesn't_ work for bitmaps (for obvious reasons). So is there some way how to invert it? Effectively a mask over the canvas. (Doing it at Morphic level should also be a viable option, provided it is possible there). Thanks, Peter

Question about Text Editor.
by Cyril Ferlicot May 1, 2015

May 1, 2015

Hi, I wanted to do a little text editor and I would like to know if someone already did one with simple features like open a file, save a file etc... I don't want to lose too much time in something that already exist. -- Cheers Cyril Ferlicot

Citizen example for manipulating a bibtex file
by Offray Vladimir Luna CÃ¡rdenas May 1, 2015

May 1, 2015

Hi, I'm using a Zotero collection for keeping track of several references I have found for my article about the experience of the outline/tree-like metaphor for writing inside Pharo (as soon as I have a presentable working draft I hope to share it with you). Now I want to make a post-processing of the bibtex file exported from Zotero. The idea is to use "shorttitle" field instead to replace the Zotero auto-generated one and have custom keys. So for example instead of: ======= @misc{_holistic_????, title = {Holistic software assessment (Uni Zurich - 2011) on Vimeo}, shorttitle = {Girba-holistic-2011}, url = {http://vimeo.com/42073344?from=outro-local}, urldate = {2014-08-19}, note = {00000} } ======= I would like to have: ======= @misc{Girba-holistic-2011, title = {Holistic software assessment (Uni Zurich - 2011) on Vimeo}, shorttitle = {Girba-holistic-2011}, url = {http://vimeo.com/42073344?from=outro-local}, urldate = {2014-08-19}, note = {00000} } ======= I have already installed Citizen and open it on the browser to see the code, but I can find any place to start with examples. Any advice on how to solve this issue will be appreciated. Cheers, Offray

RPackage extension methods using normal protocol names
by Ben Coman May 1, 2015

May 1, 2015

I saw recently how VisualWorks extensions use normal protocol names http://ia902605.us.archive.org/25/items/St4u181ClassExtensionsInVisualworks… Now that Pharo has got real package objects with RPackage, how possible is the VW convention? It would facilitate porting code. cheers -ben

[ANN] Screencast on Versionner (Part 2)
by Esteban Lorenzano May 1, 2015

May 1, 2015

Hi again, Now I made a small video on how to use Versionner to help you manage your releases and commits. https://youtu.be/cFRJDuWL-Q0 <https://youtu.be/cFRJDuWL-Q0> This is new stuff, so you will need latest Pharo 5 to use it, alternatively you can install latest Versionner into Pharo 4 (I donât know how it will work on Pharo 3, youâll probably need to load Glamour as well others). In Pharo 4, you can install it executing: Gofer it smalltalkhubUser: 'PharoExtras' project: 'Versionner'; configuration; loadVersion: '2.12.2'. cheers, Esteban
