Pharo on bitnami

by stepharo

Hi pharoers we got in contact with bitnami and I would love to see two bitnami apps around Pharo: - basic pharo - pharo + seaside + magritte + voyage (mongo pharo layer) + mongodb So who would like to help pushing this effort?

But elsewhere in the system (i.e. packages) they aren't that significant (for example, they don't appear in packages). So, we could do what you say (allow for multiple tags to a class) in a compatible way with system categories with a slightly different syntax (and some changes to RPackage): a category of: PackageName-Interface/Windows Would say that those classes belong to tags Interface and Windows The system browser could just then either parse the category (split by $- for the package name, then split by $/ to get multiple tags) or rely on RPackage to do so.

+1 to subpackages as denomination for tags if they're going to be used only to organize things hierarchically inside a package instead of used across packages.

Try where you normally define a class to select the definition and "debug it". Also using the normal class definition message-send means you don't have to come up with special compiler syntax for using class variables, slots, traits, etc. > [sign | > ^ (x sign @ y sign)]. > [dotProduct: aPoint | > ^ (x * aPoint x) + (y * aPoint y)]. > ] I can see how that might work technically with the compiler able to recognise the lack of preceding colon to distinguish a method name, but I am thinking: * its a very fine distinction for humans reading code * dropping a colon is very easy * it may lead to ambiguous fail-late errors (better to fail-early) Also *needing* to nest method definitions within the class definition seems constraining. It would be nice for methods to be able to be defined in any order. Consider a common use case where several script files are joined together which each define extensions to the same class. The above points are dealt with by the Class>>method" syntax Stef describes. A really important aspect of this is that its already a widely used convention in documentation. Now pushing that inside the block may be interesting. [ Point>>sign | ^(x sign @ y sign) ]. [ Point>>dotProduct :aPoint | ^ (x * aPoint x) + (y * aPoint y). ] [ Point>>min: aMin max: aMax | ^ (self min: aMin) max: aMax ] However a block that is not assigned to a variable is just thrown away, so possibly a hypothetical message like #define might need to be sent to the block. [ Point>>sign | ^(x sign @ y sign) ] define. cheers -ben

Re: [Pharo-users] Bug in Open Workspace from File-Browser?

by volkert

Is this change resonable. I have no idea, what the Design-Idea behind the UIManager what services is should provide. May be it make sense to have the extra services on UIManager, but think the bug is in FileList>>viewContentsInWorkspace and not in UIManager. ---- I propose for Workspace to change the current code: FileList>>viewContentsInWorkspace "View the contents of my selected file in a new workspace" | aString | self reference streamWritable: false do: [ :stream| aString := stream setConverterForCode contentsOfEntireFile ]. UIManager default edit: aString label: 'Workspace from ', self reference basename <----- WRONG to : FileList>>viewContentsInWorkspace "View the contents of my selected file in a new workspace" | aString | self reference streamWritable: false do: [ :stream| aString := stream setConverterForCode contentsOfEntireFile ]. Workspace openContents: aString label: 'Workspace from ', self reference basename And i also proposse the add a Playground case. New Method: FileList>>viewContentsInPlayground "View the contents of my selected file in a new playground" | aString | self reference streamWritable: false do: [ :stream| aString := stream setConverterForCode contentsOfEntireFile ]. GTPlayground openContents: aString label: 'Playground from ', self reference basename. and also FileList>>serviceViewContentsInPlayground and the case in ListList>>itemsForAnyFile. If ok, i can fix Workspace and add Playground menu to FileList, after i have figured out how to send an fix ;-) BW, Volkert Am 03.06.2015 um 16:40 schrieb Ben Coman: > Or do we now want such to open in Playground? > > btw, these are the relevant methods. > FileList>>FileList>>viewContentsInWorkspace > FileList>>viewContentsInWorkspace > > cheers -ben > > On Wed, Jun 3, 2015 at 6:57 PM, volkert <volkert(a)komponentenwerkstatt.de> wrote: >> The File Browser has a Context Menu "Workspace with Contents".

Re: [Pharo-users] Ring Vs Ficus

by stepharo

Hi abdelghani Welcome to this list :) > Hi Guys, > > I believe the Ring metamodel has been proposed 4 or 5 years earlier. > Is it acctually in use in the current pharo tools? which ones? Ring should be improved (probably with stubs) to support that we can create a method and that it does not create automatically the class of the method. Ring proposed strategy to query the code of a method (the one currently being in the image), or the method represented in the past or another one. and we should have a look at it. > I have been told that Martin has develloped a different model : Ficus Martin explained to me that ficus is built on two parts: one that describe the model and they other the "body " of an entity (data) and such data can be shared between multiple versions. > What are the limitations that Martin tried to fixed? > What can be further unhanced? > > Thanks. > > Abdou. >

Re: [Pharo-users] Pharo Video Tutorial: Package Tags

> So getting back to Pharo's tags, I like the fact that there are some common namings, such as many packages will have tags like "Examples", or "Tests", however I still fail to see why would you want to put one class into multiple tags and what the benefit would be. In my case I have a hard time dealing with hierarchical categorizations, I haev plenty of aspects of my code that runs accross in different ways. One case is the Model/Web/Application vs Tests, which they can be combined orthogonally. Another aspect is that I have classes that belong to different layers: Application, Interface-Web, Interface-Windows, Interface-CommandLine, Commands, Model, Persistence But them several of these classes belong to different "modules" or sets of functionality: Clients, Providers, Administration, Production With a Tag scheme, I can arbitrarily browse: All commands that are in the Provider module Persistence Tests Classes from Production and Persistence (which should be empty)
