[Pharo-dev] [Bug]: Issue 13665: File outs include external extension methods

[Sean P. DeNigris]

If MyClass is in MyPackage, with MyClass>>#extensionMethod in
*ExtendingPackage...

In Nautilus package pane, choose "File Out" from context menu. The file out
will include MyClass>>#extensionMethod, which it should not.

b.t.w. observed bug in Pharo3.0 #30850

Ah, yes, changing the font shows the underline. This seems wierd. Maybe a
silly question, but why can e.g. Mac Pages show Arial underlined, but not in
Pharo? Is underlining something we implement separately for each font?

Re: [Pharo-dev] TextMorph: No Emphasis?

[Andreas Wacknitz]

Esteban,

You are right. Changing the font solves the „problem“.
And the code snipped reveals another problem in Pharo 40120:
a right click in the resulting TextMorph gives a MNU TextMorph>>editView :(

Andreas

Re: [Pharo-dev] TextMorph: No Emphasis?

[Esteban Lorenzano]

not all fonts have underline feature available. 
if you take a 4.0 image and do not change fonts, the default fonts (DejaVu 
Sans) can underline. 
the one I usually use, for example (Source Sans Pro), can not (at least in the 
installation I have).

This comes down to the distinction between class and instance. As you know,
instance-side functionality relates to how individual instances behave while
class-side functionality related to how /all/ instances behave. In this
case, the relational mapping rules are not going to differ from one instance
to another. That is why your instructor advised you to set that up using
class-side behaviour.

If you aren't that familiar with Smalltalk - compared to C-derived languages
like Java - it may be hard to get really and truly adapted to the meaning of
"everything is an object". In this case, you have a number of classes which
represent objects mapped to a relational database, so it makes sense that
each such class is responsible for defining what that mapping is. (Although,
one could argue that proper decoupling of layers moves the responsibility of
knowing how to map the data from the individual classes to some other
objects.)


As far as doing class-side initialization, it is simply a matter of sending
the right messages to the classes at the right time. For example, you might
have a Employee class>>#setUpRelationalMappingRules method defined. Before
you can replicate the data between Smalltalk and SQL, you need to execute
that method. 

You have choices in terms of when you actually do it. 
- There is "lazy initialization" in which the initialization is done at the
last possible instant. But this incurs an overhead in that every mapping
occurrence requires the check.
- There is "application start up initialization" in which the initialization
is done early, as part of starting the application. For example, when you
connect to the database, you can initialize the mapping rules.
- There is "class loading initialization" in which the initialization is
done when you actually load the code into the image. This is typically
controlled by a class-side method called #initialize. The code loading
frameworks may execute the method automatically for you. I find too many
"corner cases" with this technique and I prefer explicit behaviours rather
than implicit ones.

The "application start up initialization" is my preferred approach. If you
imaging the UML of an application, you would have a package for your model
code, another for your persistence mechanism, and a third for your
"application". This is grossly simplified, of course. The application
package has dependencies on the other two packages, but they have no
dependencies on any of the others. In this sense, you are using the
application to tie together the model and the persistence mechanism of your
choice. At start up, you "configure" the persistence mechanism by explicitly
invoking the appropriate methods to set up the server connection, the
mapping rules, and anything else your choice of persistence requires.

Re: [Pharo-dev] Project Watch on SThub

[Torsten Bergmann]

I already thought that (as in most cases) it is mainly a 
time issue.

To Mike:

The project and an image is on CI  
https://ci.inria.fr/pharo-contribution/job/SmalltalkHub/
including the infos to run it locally. You have to install MongoDB

Basically server side is using Seaside with Amber on the client.

Code is hosted on STHub itself: 
http://smalltalkhub.com/#!/~NicolasPetton/SmalltalkHub

There is also an issue tracker: 
https://code.google.com/p/smalltalk-hub/issues/list

Things I would really like to see:
 - the project watch working again
 - maybe using Pillar(Hub) beside Markdown would be great
 - a simple field to enter and display the CI location in the project settings
 - an better query API to retrieve infos (see 
http://forum.world.st/Query-STHub-from-outside-td4728629.html
   and http://smalltalkhub.com/#!/~SWT/SmalltalkHubClient)

Maybe your pharocloud.com company want to also make an offer to host a 
custom/private STHub 
instances ...

Re: [Pharo-dev] Merging Transcript and Tool-Transcript

[Pavel Krivanek]

Hi Stef,

ThreadSafeTranscript is not the UI class. It is present in the minimal
image and it's connected to the STDOUT by default. So it makes sense to
split Transcript as a general output stream and a Morphic tool showing its
content.

Cheers,

[Pharo-dev] Package Dependencies Analysis : new features

[Baptiste Quide]

Hello Pharos Users, 

Since the first release of Package Dependencies Analysis, here is a summary of 
improvements : 

- tool is available in World Menu (Tools > Package Dependencies Browser) : 
choose your packages and browse dependencies. 
- add/remove packages into the analysis. 
- you can refresh the current analysis manually (for instance if you change a 
piece of code to remove/add dependency) 
- filter the packages displaying by name 
- button "find cycles" allows to find all cycles in the system where the 
selected packages in the tree are (it could take a while the first time you 
click) 
- contextual menu (right click) to browse scoped dependencies or find cycles 
among the selected packages in the tree 

Then, in the window displaying cycles among packages : 

- only dependencies among packages in the cycle are displaying (no outgoing 
dependencies) 
- packages appear by order (if you see aCycle : A, B, C, the cycle is A -> B -> 
C -> A) 

See more details : http://www.baptistequide.fr/packagedependencies.php 

Regards, 

Baptiste

Re: [Pharo-dev] Project Watch on SThub

[stepharo]

THub allows one to "watch" a project, meaning one can get infos on the 
commits and history of watched projects under in his own home section in 
"Recent watched events". Unfortunately it does not update, always 
displays events from 2013 and either it is my profile or a general bug 
in STHub... Any comments?


Do not expect much work around STHub since nicolas moved to another job 
and we do not have the resources to do that

locally. if somebody wants to help it would be a great help.

The ODBC package is now migrated from SqueakSource to SmalltalkHub 
and available under
  
   http://smalltalkhub.com/#!/~PharoExtras/ODBC

I also cleaned up a little bit and made some stuff working
on Pharo 3.0 again. You can now als easily load it from the config 
browser.

Repo is open for contributions. Have fun.

Rubric because it is available now and can be integrated with visible
improvements over what exists.

But, TxText should be the future. Perhaps we can already commit to it for
Pharo 4.0 and then we make it a goal for the whole community to get it
finished. I would be supportive for such a decision.

In owner coordinates it says. (TransformMorph)

However, it effectively returns a 0@0 origin.

Yes.

What do you want to do about it? Rewrite a scroll pane in a different way?
Or make sure that everything which creates over-morphs ask for global
coordinates?

I guess this has also something to do with the glamour bug inside tabs, no?

We can also abandon TxText but after we should not cry that it does not 
scale (be prepared
to fork a lot of processes in the background). But I think that it would 
be stupid so we should push igor to deliver.

And if I'm alone pushing then this is not fun.

Thanks tim.

Usually the monkey will tag your entry to ready to integrate and we 
harvest them.
After this is also nice to write a comment saying that your change is ok 
in the latest image and we will integrate.
We would like to change the integration process but we are not yet 
there. Git is needed first.
We are getting more integrator: clement (on the compiler domain), 
nicolai and this is good. Sven is integrating changes related to the network

Re: [Pharo-dev] Doubt in Pharo

[stepharo]

Hi Dokania

I hope that you do not doubt that Pharo is a cool system :)

Hello,

I am creating an Object Relational Mapper in pharo using sqlite.

While creating database I am using a dictionary for columns of Database. This 
gives me Keys as column name and values as Data type of those.

So suppose Employee is the the table name, with ID->Integer, Name->Text, 
Salary->Float.

emp:= Employee new.
Now emp is a row of table, so for each row user has to create instance of 
Employee and then feed values to it. Later on he can pass message insert query 
to emp.

So I was creating this dictionary for column at the instance side 
initialization of Employee.

My instructor suggested to do that in class side initialization,

My Doubts are:

1. Why should we do class side initialization instead of instance side 
initialization.


Because class side initialization is executing once when the class is 
loaded in memory.
And I imagine that you do not want to change and execute the mapping 
declaration for every single

instance you will create. isn't?

So

Object subclass: #Employee
instanceVariableNames: ''
classVariableNames: 'Mappings'
category: 'Foo-Model'


Employee class>>initialize

Mappings := { #ID->Integer . #Name->Text. #Salary->Float } 
asDictionary


makes a lot of sense.

or

Object subclass: #Employee
instanceVariableNames: ''
classVariableNames: ''
category: 'Foo-Model'

Employee class
instanceVariableNames: 'mappings'

Employee class>>initialize

mappings := { #ID->Integer . #Name->Text. #Salary->Float } 
asDictionary


Read pharo by example to understand the difference between class 
variable (Shared Variable) and class instance variables


2. Could you please refer me to the link which explains how to do class side 
initialization. Because when I do Employee new, I see only instance side 
initialization is being called.


Employee initialize

you send a message to the CLASS itself to get **ITS** initialize method 
execute. Normally when you load the class its initialize method is 
automatically executed.


When you do Employee new
=> Employee basicNew initialize
=> anEmployee initialize
=> anInitializedEmployee




Thanks,
Harshit

Not really. The contract of submorphBounds should be that it returns an
absolute coordinate, as far as I understand.


> Why do you use a TransformMorph there?

It is used for example in ScrollPane. This means that if you embed a
TextMorph inside a ScrollPane, you will have the same problem with
completion:

scrollPane := ScrollPane new.
pasteUpMorph := PasteUpMorph new.
scrollPane scroller addMorph: pasteUpMorph.
scrollPane openInWindow top: 100; left: 100.

pasteUpMorph submorphBounds "(0@0) corner: (50@40)"

And this locks the UI too. (Loaded the code 20 times, every time after a
fresh image start up. Two times I got a locked
ui after the first two clicks).
And I don't understand this code :)

This seems correct to me: a transformMorph is the one which shift its
contents (and reset the origin to its top left corner ?).

Why do you use a TransformMorph there?

Re: [Pharo-dev] Doubt in Pharo

[Peter Uhnák]

Hi,

I'm sure someone can give a much better and more in-depth explanation but
here goes:

1. Class side initialization is generally used to create fully functional
objects. If you use just instance-side you might forget to set some
important value (let's say ID) which would leave the object in invalid
state. Another reason would be that it shows what does one really need to
create a valid instance. If you have Empoyee class>>id: anId name: aName
you will now know that salary is actually not needed and the object is able
to cope with that. (And you can set it later). Yet another reason would be
setting some additional/default values (however this can be done also
internally on the instance-side).

2. Some elementary examples might be Rectangle or Point in Kernel >
BasicObjects package. Generally you wouldn't send Employee message new
directly, because that is class-side's job now, but rather you send the
actual values: Employee id: 123 name: 'John Doe'. "answers with an Employee
instance"

Sound great ! Are you looking for application chapters?
We can contribute something with one of my PhD student.

Thank you for your work.
