Understanding ZnJSONReader mapping?
by Tim Mackinnon June 7, 2018

June 7, 2018

Hi - is there something I can read/study to get a bit more familiar with Json mapping? I have read the Pharo enterprise book (chapter 8). Iâve been using NeoJSONObject but then it occurred to me that maybe I could map better domain objects directly and simplify things. However it seems that the intent of mapping is just for simple things like an array of points - whereas if I have 15 different domain objects (albeit with a type key), then Iâm wondering if I should just wrap json nodes on usage? In fact Iâm wondering what the point of mapping is if itâs so simple - or maybe Iâm missing an important concept? Tim Sent from my iPhone

Re: [Pharo-users] more on "can't get keyboard shortcuts to work on Mac"
by Gregg Williams June 7, 2018

Tim and Ben, Thanks for your help. Sorry for not being clear. When I said "I just can't get keyboard shortcuts to work on Mac," what I should have said is "I just can't get Pharo-specific shortcuts to work on the Macintosh implementation of Pharo" (6.1 is what I'm using BTW). Maybe I should have said "keymap shortcuts"? I'm talking about things like Meta+Shift+f for 'find class', and Meta+x, Meta+m for 'remove method'. I've looked for what the definition of Meta is for Mac OS. All I can find is meta-click is Shift+Option+click, but that doesn't seem to work. Option + <many keys> gives "special characters" like â, Ã, and Å. I hope that now you can simply say, "Oh, of course, what you need to do isâ¦". Thanks! > I just can't get keyboard shortcuts to work on Mac. I?ve tried a lot of stuff, more than I can list here. Here are some things I?ve tried: > > * searching the Pharo by Example book > * turning off all Mac keyboard-macro programs > * switching from extended to standard US keyboard > * looking at options in System Preferences > Keyboard > > > If you?re on the Mac, do you have this problem? If so, what?s your solution? Thanks! >

Hi guys, I have been doing some things with Dolphin, actually feel very confortable with it, but now I am trying to learn Pharo. I have noticed that many things are quite similars, but others are very differents, one of this things is the Visual Part, can someone point me out some good tutorial for Morph and MVC, I trying to understand the use of these two "worlds" and I want to "play" a little with them. Thanks. MatÃas.

need help loading third-party packages
by Gregg Williams June 5, 2018

June 5, 2018

Hi--another question, this time on loading an external package into Pharo. I want to do some work manipulating text, so I thought I would start by reading the source code for an existing package that works on text. Here's what I did: On smalltalkhub.com, I found a package called Citezen, from team RMoD, and downloaded the .mcz file. There were many versions, so I downloaded the one with the latest timestamp. It helped that its name was Citezen-All-sd20.mcz. I've tried adding this to my current Pharo 6.1 image in two ways: 1) by dropping the .mcz file onto the window of PharoLauncher, and 2) moving the file into my computer's package-cache directory. I had roughly the same problems with both. Problem 1: There were multiple options for telling the system what do to with it: Load, Load Version, Merge version, Open version, and Extract all to.... Problem 2: Once I do that, I get to a window with buttons at the top: Browse, History, Changes, Load, Merge, Adopt, Copy, Diff. Problem 3: Once I chose one of these, I got at least a half-dozen "Can't find dependency <filename> Ignore?" messages (for example "...Citezen-Parsers-cdlm.13" and "...Citezen-Tests-sd.39"). The default button for this was "Yes", so I chose this. This started some downloading of files, a process that sometimes got "stuck" and never completed. Not knowing any better, I then launched Pharo 6.1 (Stable). I could see no indication that Citezen had been "added" to the system. Anyway, in a system browser, I searched for the string "Citezen" and found five Citezen packages: All, Model, PArsers, Rendering, and Tests. But when I selected any of them, no content appeared in the Class pane. Also searching for a class containing "Cite" found nothing. Surely, other beginners have had the same problem as me. I would appreciate pointers to any existing resources that would help me out, or whatever help you'd care to give me. TO RECAP, I want to load third-party packages and read their source code. What's the best way to do this? Many thanks!

Loading Local Repositories with Iceberg
by Evan Donahue June 5, 2018

June 5, 2018

I'm using the Pharo 6.1 image with the Pharo Launcher. I have committed changes to several local github repos through Iceberg. I would like to be able to clone a new 6.1 image and load all the locally committed packages. I have "Share repositories between images" checked in both images, and the path looks right, but I do not see any of my repos in the fresh image. Is there something I need to do to load them? I tried "add local repository" but it claimed none of my repositories had any packages to load. I have had no trouble pushing to github and downloading my packages again from there on a different computer, but I am afraid to try it on the same computer in case the repositories collide. In short, what is the best way to set up the project I was working on in a fresh image so I can continue working on it? Thanks, Evan

How does Metacello check for installed packages in the image?
by HernÃ¡n Morales Durand June 5, 2018

June 5, 2018

Hi, I have a Pharo 6.1 image with packages loaded manually (without BaselineOf or ConfigurationOf). Now if I evaluate a Metacello script which would install the package already installed in the image (for example via dependency), is there any check performed against the RPackages or similar to avoid loading it again? Cheers, HernÃ¡n

Scripting package updates
by HernÃ¡n Morales Durand June 5, 2018

June 5, 2018

Hi guys, I am working on Pharo 6.1 and already have an image with multiple packages loaded via Iceberg. Every time I want to load other's remote changes to my image I have to open the Iceberg UI and select repository, synchronize, update, hit fetch + merge (or pull). Does anyone has a script to automate this process and avoid manually open the UI, etc? Cheers, HernÃ¡n

Hi, I am working with a GitHub enterprise installation that resides under a custom domain (e.g., github.example.com) I can clone the repository using Iceberg and ssh: git@github.example.com:user/repo.git How can I tell Metacello to load a baseline from that repository?
