Re: [Pharo-users] What UI direction now (or in the near future)?

Hi Petr, what you should do is use Spec for the UI. If you want to write your own list component you can do that in Morphic and integrate it in a Spec UI. All pointers to info about Spec were given by Sven on Feb 13th in one mail entitled âLearning Spec'. I will quote his first 3 pointers here for your convenience: > Here is a guide to documentation about Spec, most recent first. > > > There is an excellent presentation by Johan Fabry did during the last Pharo Days, 'Using Spec to Build a UI'. *MUST WATCH* (the video is not yet fully public, but soon will be, the link should work though): > > http://youtu.be/OL23s9ZUIR0?list=PL4actYd6bfnz98ngrKALwwStl3C3odEKG > > The slides are also not yet available, but soon will be (the talk is much better that the slides on their own). > > > This draft chapter 'Spec: a framework for describing user interfaces' for an upcoming book: > > https://ci.inria.fr/pharo-contribution/view/Books/job/PharoBookWorkInProgre… > > > Look in the image. > > Browse the hierarchy below AbstractWidgetModel in the category Spec-Core-Widgets in Pharo 4, look at the protocols called 'protocol' & 'protocol-events' mainly.

Re: [Pharo-users] Filetree repository from string error

by Sven Van Caekenberghe

Well, it could be that it works, but that is by accident. When using backslashes instead of forward slashes, the path is not parsed correctly. Even FileSystem paths are represented differently (internally of course, when going to the file system, eventually you need backslashes on Windows). But I am not on Windows, so I am not placed well to discuss the actual experience. > On 25 Feb 2015, at 16:38, Jan B. <bliznjan(a)fit.cvut.cz> wrote: > > Hello Sven > > All I had to change is the one additional slash and it works now, thank you > a lot. > > So this works: > > Metacello new > baseline: 'OurProject'; > repository: 'filetree:///C:\Users\User\Pharo\ourproject\repository'; > load. > > I got mislead by that when I add filetree repository via monticello GUI, it > shows there as repository > filetree://C:\Users\User\Pharo\ourproject\repository > > Jan > > > Sven Van Caekenberghe-2 wrote >> Jan, >> >> That is wishful thinking, there are no backslashes in URLs.

Re: [Pharo-users] Filetree repository from string error

by Jan B.

Hello Sven All I had to change is the one additional slash and it works now, thank you a lot. So this works: Metacello new baseline: 'OurProject'; repository: 'filetree:///C:\Users\User\Pharo\ourproject\repository'; load. I got mislead by that when I add filetree repository via monticello GUI, it shows there as repository filetree://C:\Users\User\Pharo\ourproject\repository Jan Sven Van Caekenberghe-2 wrote > Jan, > > That is wishful thinking, there are no backslashes in URLs.

Re: [Pharo-users] Filetree repository from string error

Jan, That is wishful thinking, there are no backslashes in URLs. Furthermore, the drive is not a host, but is part of the path, hence you need 3 backslashes: Try: 'filetree:///C:/Users/User/Pharo/ourproject/repository' asUrl. 'file:///C:/Users/User/Pharo/ourproject/repository' asUrl asFileReference.

Filetree repository from string error

by Jan B.

Hello I use Windows 7 with Pharo 4 (latest image and VM) and I have our project in filetree on disc, repository is not yet created in monticello. When I run following code in playground, which should create and load it, I get error ZnPortNotANumber Metacello new baseline: 'OurProject'; repository: 'filetree://C:\Users\User\Pharo\ourproject\repository'; load. Screenshot: https://monosnap.com/file/HuHMjxAfVa53eZAev3KAXL4J7bTjGW.png I would gladly provide any other information, or try anything, if needed.

Re: [Pharo-users] What UI direction now (or in the near future)?

by Alexandre Bergel

Morphic has been around for over a decade. Probably it will stay for a while. Athens is quite stable. However it is not made to do UI. It does not do much for event handling. Roassal does the drawing with Athens and the event management with Morphic.

Re: [Pharo-users] BaselineOf vs ConfigurationOf

by Thierry Goubier

I'm sure Dale will precise this, but... BaselineOf is the same as a #baseline: in a ConfigurationOf. It describes dependencies, packages and groups for a project, without versions. On loading, a BaselineOf will behave as a #development version in a ConfigurationOf which is to load the latest versions of the packages listed (and whatever dependencies listed). BaselineOf becomes very convenient when you combine that with a repository which understand branches, such as git. Then, you say which branch or release tag you want through the repository url, say it's a baseline, and, et voilÃ , you have it (it loads the latest version on that branch or tag). Repositories urls which support branches and tags are github:// and bitbucket:// urls; which support branches (and not tags) are gitfiletree:// urls. Really, really makes things a lot easier than configurations. Took me a while to start using it, now, can't do without. These days, I'm just using Metacello scripts to load stuff out of baselines instead of configurations for allmost all my stuff.

Re: [Pharo-users] BaselineOf vs ConfigurationOf

by Damien Pollet

Thierry or Dale will confirm, but basically that's the gist of it. For git projects, you can specify dependencies to all things that refer to commits in git. So you can depend on a particular commit, on a tag, the tip of a branchâ¦ Therefore the release/version management part of metacello in ConfigurationOfâ¦ becomes mostly irrelevant, since you can encode it in how you organize and use your git repo.
