ANN - Pre-compiled Pharo Spur32 VM for Debian Stable
by Jan Vrany Jan. 14, 2016

Jan. 14, 2016

Hi there,Â the Pharo Spur VM provided by the Pharo team does not runÂ Debian Stable and possibly on other more conservative Linux distributions.Â You may find a pre-compiled Spur32 Pharo VM that runs onÂ Debian Stable (and possibly on other distros) at:Â https://swing.fit.cvut.cz/jenkins/job/pharo-vm-spur-swing/ Zeroconf for those is also available:Â curl http://swing.fit.cvut.cz/download/pharo/vm-spur-swing | bash wget -O- http://swing.fit.cvut.cz/download/pharo/vm-spur-swing | bash Thanks a lot to Esteban and Damien for their help! Have fun!Â Jan

I guess this field should exclude returns and even all trailing whitespace. Maybe this should be the default for all such controls (?)

I guess its not intuitive, but I only ever type the Issue Number of the slice, since that is unique and there is usually only a couple of items > Double click on it, nothing happens. Choosing a default double-click action would need some community discussion. Maybe <Merge> ?? > Remember that thing appears to think double clicks do not matter. > Right click on it, see only sorting options, nothing relevant. I don't think I have ever used the sort options.

That was probably not the right button. Close the > window. I never use <Browse>. I'm no sure of its value but note however that Monticello is a general tool for loading packages, which has been pressed into service to load slices (which is just a package binding a set of dependent packages together.) <Browse> might be good for exploring a completely new package before its loaded the first time. > Click on History. Get a window with only the description of the selected > slice, what use could that possibly have? Not so much for reviewing slices which have a shallow history. But again Monticello is a general package management tool. For this, search on 'strings' , then select package Collections-Strings. Observe how version Lorenzano.385 is underlined. This version is the one currently loaded in the image. Observe also Polito.383 is bolded. This is not an an ancestor of the currently loaded package version. You can see Lorenzano.385 has ancestor Lorenzano.384 which has ancestor Lorenzano.383. Select Lorenzano.385 and click <History> and you will see Polito.383 missing from the list. > Click on Changes. Stuff blinks on screen for a couple seconds, to fast to > read. Lucky you ;) it takes a while from Australia. I'm not sure of best practice, but personally, to review slices I only ever use <Merge> in the repository window since this provides a three-way diff. I'm not sure... but I don't think <Changes> does (?) Back when I started with Pharo using this repository <Changes> button gave different results depending on factors I couldn't track down. I've never had a problem with <Merge> and <Merge> is what the CI monkey uses. Now I regularly use the <Changes> button back in the first Monticello window. It compares to the selected repository, so as Stef mentioned on Fogbugz, when you do come to submit your first slice select to compare Pharo50/main rather than Pharo50Inbox/main. If its the first time this release cycle a package is updated, the ancestor won't be in Inbox and so every method is counted as a change (probably it should be better) btw, the CI monkey copies integrated packages from the latter to the former. > I guess that means to reassure me.

Still to narrow. > Maximize the world window. Did not change the size of the window. > Maximize the window again. Weird that changed the size and position a bit. I > guess that unmaximized that window that was not really maximized. > Maximize the window again. Okay now I can see the diff. Interesting find. You probably worked this out, but just to be clear... When the window was first maximized it recorded this was its state, and that was not reset when the world was maximized. So the next click of the button unmaximized it. And the final click properly maximized. So I see two alternatives: * a maximized window should follow the resizing of the world's native window * the maximized state of windows is reset when the world is resized. Lets see what others think. > Okay now, how I am supposed to post comments? I guess I should copy the > relevant bit of code, paste it in the browser, and add my comment.

Human nature is to adapt, and after a while become oblivious to these issues - like automatically stepping over that wobbly cobblestone in your front path without thinking about it. Fresh eyes are really valuable. In case its useful to adap, I'll summarize the workflow I've optimised for me personally: 1. Refresh PharoLauncher. 2. Right-click on latest numeric build and <Create Image> 3. For image name keep build number and replace left with issue number. e.g. "Case17363-50526". Sometimes I append the issue title from fogbugz. Sometimes I need a few images for a case e.g. "Case17363-50526b" usually created from "Local" templates, and its annoying when I forget. 4. Open Image, Monticello, Pharo5Inbox repository. The issue number shows in the native window title, so type that into search. 5. Select latest slice and <Merge> to review changes. I don't proceed with pushing the final execute <Merge> button in this window. I leave it open so after merging I retain a list of the changes. 6. From first Monticello window open a second Pharo5Inbox repository window. Select same slice and <Merge>, then push final <Merge> button to execute. ((For a long time I've been meaning to put a "Keep open" checkbox next to the final <Merge> execute button so I don't need to do this dance. Maybe soon)) 7. Browse from listing changes in retained window, insert appropriate breakpoints to understand the changes and form the questions to ask to learn more. > > Feel free to forward this message to the mailing list.

I didn't want you to feel pressured being publicly volunteered for something you weren't ready for. But obviously your up for it, so cool. cheers -ben > > Now, I'll post my comment on the slice on fogzbugz.

Sounds like Goodies
by Torsten Bergmann Jan. 14, 2016

The dolphin 7 open source repo includes some contributions from Udo including an implementation for Levenshtein distance [1]. It's a single method + test case and easy to port. The algorithm [2] is useful to find out how close two strings are (approximate string matching). There is also SoundEx [4] and SoundsLike [5] (Soundex, Double Metaphone and NYSIIS algorithms) for Pharo available. I just want to let anyone know - just in case someone works on a more "robust" autocompletion that is also typo aware. ;) Having custom templates [6] like in Eclipse would also be good to have in future Pharo code editor. More to add to the wishlist? Damn ... Santa already passed by... Have fun T.

Code reviews

Once a Slice has been submitted to the Pharo5Inbox the associated Issue on Fogbugz is <Resolved> to "Fix review Needed" - people review it out and comment. Unfortunately with limited resources, sometime resolved issues can languish if reviewer don't feel its within their expertise, and often it falls the to small group of the core-devs from Inria. As Pharo grows more popular we may need some improved processes to reduce load on core-devs. I'd be interested in what you've seen work in other environments. Have you seen these... http://pharo.org/contribute-propose-fix https://pharo.fogbugz.com/?W68 cheers -ben

Problem with gitfiletree numeration
by Mariano Martinez Peck Jan. 14, 2016

Jan. 14, 2016

Hi guys, I wanted to know how you manage this situation. I had my already existing project in shub repo. Last version was OSSubprocess-MarianoMartinezPeck.43. I then created a github repo, cloned it, and then with gitfiletree I commit for the first time. The problem is that the commit I did with GitFileTree received this MC version: OSSubprocess-MarianoMartinezPeck.1. Normally I would not care. But in this case I do care because every in a while I would like to move/publish some versions from github to shub. And OSSubprocess-MarianoMartinezPeck.1 has 2 problems: 1) It has an older version number but newer contents 2) It's number is not unique. So if I copy versions created from github to shub, they would override those versiones created in shub (like the very old OSSubprocess-MarianoMartinezPeck.1 from shub) ?? How do you normally solve this? Thanks! -- Mariano http://marianopeck.wordpress.com

Right to Left languages and fonts
by Jimmie Houchin Jan. 13, 2016

Jan. 13, 2016

Hello, I briefly tried to copy/paste, read from file, some Hebrew text. I simply get some strange characters. From a brief search of the archives. I did not find any means of doing a right to left language. I also am not sure how to use a Hebrew font. Font issues would also apply for when I want to use Greek. What would be needed to do right to left and use the right Hebrew font? I believe these issues would also apply to anyone wanting Arabic or any other such languages. The last message I can easily find is in August of 2014. Maybe Pharo isn't the right tool for this job at the moment. But I did want to explore the potential of it being so. Thanks for any help. Jimmie
