Adding a #development version of a Git project in the catalog
by Damien Cassou Sept. 22, 2015

Sept. 22, 2015

Hi, I have a BaselineOfJenkins on github and I would like to add a ConfigurationOfJenkins in the catalog. For the #stable versio, I wrote: stable: spec <symbolicVersion: #'stable'> spec for: #common version: '1.0.0' v1_0_0: spec <version: '1.0.0'> spec for: #'common' do: [ spec baseline: 'Jenkins' with: [ spec repository: 'github://DamienCassou/pharo-jenkins:v1.0.0/src' ]; import: 'Jenkins' ] But I don't know what to do for the #development version. I tried this but Metacello does not want it: development: spec <symbolicVersion: #'development'> spec for: #'common' do: [ spec baseline: 'Jenkins' with: [ spec repository: 'github://DamienCassou/pharo-jenkins:master/src' ]; import: 'Jenkins' ] On http://blog.yuriy.tymch.uk/2015/07/pharo-and-github-versioning-revision-2.h…, Yuriy talks about a pre-release, but this requires changing the #development description for each release. -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." --Winston Churchill

Mathex first release is out.
by Julien Delplanque Sept. 22, 2015

Sept. 22, 2015

Hi all, I'm sending this mail for those who are eventually interested in the Mathex package I announced in a precedent mail (http://forum.world.st/Mathex-Generating-latex-math-from-Pharo-td4848409.html) Mathex has now its first release: 0.1 (the latest release will always be in the same state as master branch, new features will be on bleed till there is no new release. So basically, releases are not really usefull except for announcing them :) ). Here is a list of changes/additional features since the last mail: ===================================== - Greek letters are defined as globals: Alpha, Beta, ... - Additional packages for more latex commands (https://github.com/juliendelplanque/mathex#load-additional-package) - GT-Inspector extensions to: * explore the tree formed by Mathex objects * see the LaTeX code generated by a Mathex object * Have a preview of the compiled LaTeX code using pdflatex - The possibility to define custom commands made of Mathex objects composition using blocks (see: https://github.com/juliendelplanque/mathex/wiki#advanced-uses) - Documentation available on the wiki (more to come) - A code rewriter and its GUI (not documented yet and still experimental) that allows you to write "Mathex Smalltalk" ie Smalltalk code where #asMathex message is sent to all literals automatically. This make the code lighter because in spite of '(1 asMathex + 2 asMathex) equal: 3 asMathex.', you can write: '(1 + 2) equal: 3' and get Mathex objects that are able to generate LaTeX. - The possibility to create Mathex objects using symbols. For example: '#vdash asMathex' returns a MVdash object. - Added messages to do things like: '$a asMathex ==> $b asMathex' and get the latex code 'a \Rightarrow b'. - Some refactoring And probably things I forgot Some links: ======= Mathex github repository: https://github.com/juliendelplanque/mathex Mathex 0.1 release: https://github.com/juliendelplanque/mathex/releases/tag/0.1 (you can just follow instructions in this mail or in the README to get it). Mathex wiki: https://github.com/juliendelplanque/mathex/wiki. Install Mathex package: ============== Metacello new baseline: 'Mathex'; repository: 'github://juliendelplanque/mathex/repository'; load. Install Mathex extensions (after Mathex package installation): ==================================== MLoader loadArrows. "Load Mathex-Arrows" MLoader loadBinaryOperators. "Load Mathex-BinaryOperators" MLoader loadLoglike. "Load Mathex-Loglike" MLoader loadMisc. "Load Mathex-Misc" MLoader loadRelations. "Load Mathex-Relations" Install GT-Inspector extensions (after Mathex package installation): ======================================== MLoader loadGTInspectorExtensions. Add a preview of the LaTeX code compiled in GT-Inspector (only for linux users from now, sorry for others) ================================== See: https://github.com/juliendelplanque/mathex#add-a-preview-of-the-latex-code-… Comments, help and critics are welcome. Regards, Julien

Rectangle center rounding
by Jan BlizniÄenko Sept. 22, 2015

Sept. 22, 2015

Hello I came to problem with Roassal which originates in Rectangle class. Although rectangle holds its points (origin and corner) in float (not rounded) numbers, the Rectangle>>#center method rounds it down to integers. It causes wierd behavior in Roassal where moving elements in some ocasions are "jumping" to all directions like a jelly. I understand it is for performance reasons, but I think this optimisation is not on the right place. Rectangle origin: 0.9(a)0.9 corner: 3@3 just does not have center 1@1, it is way too far from the real center. Shouldn't the rounded method be separated as for example roundedCenter or something like that to eliminate the confusion?

Displaying custom Magritte view on FAMIX model
by Peter UhnÃ¡k Sept. 21, 2015

Sept. 21, 2015

Hi, I would like to build custom magritte view for a FAMIX model, however it seems that Fame/Metanool are somehow interfering with it.. Imagine a simple model (a class with an attribute): ~~~~~~~~~~~~~~~~~~~~~~~~~~~ cls := FAMIXClass new name: 'Something'. (attr := FAMIXAttribute new) name: 'myAttribute'; declaredType: (FAMIXClass new name: 'OtherThing'). cls addAttribute: attr. ~~~~~~~~~~~~~~~~~~~~~~~~~~~ now I can open the magritte description ~~~~~~~~~~~~~~~~~~~~~~~~~~~ attr mooseDescription asMagritteDescription asMagritteMorph openInWindow. ~~~~~~~~~~~~~~~~~~~~~~~~~~~ However this is a meta description, which I don't want... So second option was to build it manually; I extract descriptions that I am interested in.... ~~~~~~~~~~~~~~~~~~~~~~~~~~~ container := MAContainer new addAll: ({ attr mooseDescription at: 'name'. attr mooseDescription at: 'declaredType'. } collect: #asMagritteDescription). (container asMorphOn: attr) openInWindow. ~~~~~~~~~~~~~~~~~~~~~~~~~~~ However the problem with this is, that the declaredType is presented as TextField, which is not very useful. So I'm kind of lost... basically what I want to do is to have a MAContainer that contains both the Attribute's name and #declaredType's name. Is this possible? Thanks, Peter

by Damien Cassou Sept. 21, 2015

Sept. 21, 2015

Hi, just to let you know I extracted some code from the Launcher to query Jenkins servers from Pharo. With this project, you can write code like: | pillar zipArtifact | pillar := JenkinsServer pharoContributions jobs detect: [ :job | job name = 'Pillar' ]. zipArtifact := pillar lastSuccessfulBuild runs anyOne artifacts detect: [ :artifact | artifact name = 'Pillar.zip' ] ZnClient new url: zipArtifact url; downloadTo: 'Pillar.zip' The (very simple) code is on github: https://github.com/DamienCassou/pharo-jenkins -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." --Winston Churchill

Depending on something already in the image
by Damien Cassou Sept. 21, 2015

Sept. 21, 2015

Hi, my project depends on GTSpotter and GTInspector which are already in Pharo. How do I describe these dependencies in my ConfigurationOf so that Metacello does no load them? I did spec configuration: 'GTInspector' with: [ spec version: #stable; repository: 'http://smalltalkhub.com/mc/Moose/GToolkit/main/' ] but Metacello loaded many things (including Roassal2) -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." --Winston Churchill

externalizing Magritte descriptions and partial forms
by Peter UhnÃ¡k Sept. 21, 2015

Sept. 21, 2015

Hi, I'm trying to wrap my head around Magritte but I am failing hard... Imagine I have object with three attributes. ~~~~~~~~~~~~~~~~~~~ Object subclass: #Person instanceVariableNames: 'name age email' ~~~~~~~~~~~~~~~~~~~ Now the normal way would be to add magritte descriptions... ~~~~~~~~~~~~~~~~~~~ Person>>descriptionEmail <magritteDescription> ^ MAStringDescription new label: 'Email'; accessor: #email; beRequired; yourself ~~~~~~~~~~~~~~~~~~~ etc for the rest... And now if I want to manipulate it I would do... ~~~~~~~~~~~~~~~~~~~ |p| p := Person new name: 'Someone'; email: 'some(a)one.com'; age: 20. p asMagritteMorph addButtons; openInWindow. ~~~~~~~~~~~~~~~~~~~ So far so simple... however what I don't understand: 1. What if I want to have different descriptions for the same attribute? For example in some views the email is required and in others it is not. 2. Must the description be part of the object? Maybe I am still not fully committed to the having massive protocols with tons of extension methods instead of externalizing the code to separate adapters and whatnot. 3. What if I want only partial rendering? For example in one view I want to be able to edit only name and age, and in another one all three. Since #asMagritteMorph collects everything I don't see how I can customize this. Now I do expect that all these things are possible, however as I'm just starting with Magritte it's a lot of information and concepts to absorb... so any help is appreciated. Also, is there maintained Magritte-Spec? I've seen something by Sean, but it's from 2013 with a single-ish commit. Thanks, Peter
