Yes it can be nice to have a single documentation so that when we improve it 
will benefit directly 
to the tools.

Sometimes this is arcane to me. 
I think that I would have to concentrate and do a full review of code using 
tons of new tests :)

[stephane ducasse]

we have the unique feature or rewriting deprecation
now this is true is this is why tests help a lot. 
I migrate regularly all our software: microdown, pillar, moose and more. 
And this is life.
Now do not expect that all the suddent Pharo 10 will improve and see bug fixed.
Even apple or microsoft or oracle do not support for free old versions. 
And the fixed versions of P10 is called P11 and P12.

Cool. 
The first thing I suggest is to take the stupidiest issue like adding a comment 
in a method
or fixing a badly written comment and make a PR.
I like to do this trivial things because there are easy to give a positive 
slant on my energy.

For the contributions feel free to pick what you like

- Some easy things are: better comments, improving test coverage
- Now I’m pretty sure that we can get collection improvements
- This one could interest you: underscores in numeric literals
https://github.com/pharo-project/pheps/pull/18/files
We had long design discussions and I think that the result is good but we never

I will start to work on a little tutorial to build a clock in Bloc based on the 
work on Renaud and I will add it to the Bloc 
chapter. A general problem about software is that it is often fun to develop 
but people forget the documentation part. 

So I will try to learn bloc and write what I understand and share it.

[stephane ducasse]

Thanks for the pointer!!!

For me I’m lacking time to improve Microdown, so I will focus on the features 
I have on my todo
- > support
- $ $  and 
$$
- I got some ideas about a nice extension mechanism :) quite cool in 
fact


Doing a parser is not that simple. In microdown dev I integrated the latest 
version of the paragraph
parser made by Kasper and now I will check it for real. 

I briefly checked it and :)
well microdown is much much simpler and also more powerful when it is related 
to environment arguments (quite cool to have reference to figs, math 
expressions, extensibility). 

Now I will review it carefully and pick what I find useful. 
I will start to improve the readme because microdown is quite sexy at the end 
and all the books 
I’m producing are done with it.

(180 people at Koln 2019)!
- Students can get free registration and hosting if they enroll in the the 
Student Volunteers program. See below.


## Developers Forum: International Smalltalk Developers Conference

## Call for Student Volunteers
Student volunteers help keep the conference running smoothly; in return, they 
have free accommodations, while still having most of the time to enjoy the 
conference.

Pay attention: the places are limited so do not wait till the last minute to 
apply.

Conference details:
Send an email to Steven Costiou  and  Oleksandr 
Zaitsev  with:

title: [ESUG 2024 Student]
name, gender, university/school, country, email address
short description of you and why you are interested in participating

For which period is accommodation covered? Accommodation is covered from Sunday 
from 8 to 11 July 2024 (including nights from Sunday to Monday and from 
Wednesday to Thursday ). Students will be hosted in student rooms. ESUG 
additionally covers the lunches during the week and one dinner.

Duties include handling registration as people arrive at the conference, 
filling coffee machines, collecting presentation slides for ESUG right after 
the presentation is given, being present at an information desk to answer 
questions, and generally being helpful. Student volunteering makes the 
conference better, takes a fairly small amount of time, and doesn't 
significantly interfere with enjoying and learning from the conference. Please 
note, that this role requires discipline and constant attention to all 
attendees.

Information about hotel
Student Volunteer rooms are booked at (to be announced). If you are a student 
volunteer, do not book yourself, we have arranged the booking already!

[Pharo-users] Call for chapters

[stephane ducasse]

Welcome to this collaborative book. We are looking for contributions to new 
tools in the Pharo ecosystem. Here is a non-exhaustive list of possible tools 
we have in mind.

Development tools such as refactoring, memory usage, and new approaches to 
debugging
Development tools such as UI builders
Development tools to develop compilers
Tools for modeling such as Cormas, Moose
Libraries as basis for advanced tools
Each chapter will be reviewed by three reviewers.

We expect the chapters to

describe the tools,
present some clear scenarios,
describe key elements of implementations,
evidence of use of the tools,
Submission process:

A chapter must be written in Microdown. Writers may want to clone the current 
repository and use Pillar (see https://github.com/pillar-markup/pillar and 
https://github.com/pillar-markup/microdown). The Sample1 folder in the Chapters 
folder contains a sample chapter.

The authors should send an email to stephane.duca...@inria.fr 
<mailto:stephane.duca...@inria.fr>, g...@dmi.uns.ac.rs 
<mailto:g...@dmi.uns.ac.rs>, and juanpablo.sando...@uc.cl 
<mailto:juanpablo.sando...@uc.cl>.

The authors should then do a PR to this repository with their chapter 
containing all their files.

The length of each chapter is not fixed but authors should make sure that the 
chapter is not either too short or too long. It is worth to see that the format 
is good for tutorials but is not compact. We will give feedback on this aspect.

As usual the material should be new and unpublished.

Citations should be expressed using the microdown citation e.g. 
{!citation|ref=Blac09a!} using {!citation|ref=Blac09a!},

A chapter must be spellchecked with a system such as grammarly,

if needed, each chapter should contain a bibfile having the same name than the 
main folder file,

if needed each chapter should contain a folder named 'figures' that contains 
the figures of the chapter.

The Sample1 folder illustrates this structure, it contains:

Sample1.bib
Sample1.md
figures/pharo.png
figures/rmod.png
This book will be published via the book-on-demand program of http://bod.fr 
<http://bod.fr/>. It will be published on the Bibliotheque Nationale de France 
and it will be available on most public platforms such as amazon.com.

S. Ducasse, G. Rakic and J-P Sandoval

For our May presentation, Stephane Ducasse will present the vision behind Pharo 
and how that is been implemented incrementally across multiple releases. In 
Stef's words: "The vision of Pharo is based on three pillars: 
• First we want to make sure that Pharo is used to develop complex and robust 
systems (by complex we means multiple millions lines of code or objects).
• Second we want Pharo to be a modular system that can be versatile (Pharo on 
iot, on large servers, in the web browser….)
• Third Pharo should be an evolvable system that can adapt to new needs 
(modular tools, first class slot, new debuggers, packages…).

[Pharo-users] Fwd:  Just scheduled: Stephane Ducasse - Pharo: a vision implemented step by step

[stephane ducasse]

Hi guys

I will present some points around Pharo and P11 in particular 


For our May presentation, Stephane Ducasse will present the vision behind Pharo 
and how that is been implemented incrementally across multiple releases. In 
Stef's words:

"The vision of Pharo is based on three pillars:
- First we want to make sure that Pharo is used to develop complex and robust 
systems (by complex we means multiple millions lines of code or objects).
- Second we want Pharo to be a modular system that can be versatile (Pharo on 
iot, on large servers, in the web browser….)
- Third Pharo should be an evolvable system that can adapt to new needs 
(modular tools, first class slot, new debuggers, packages…).

Sometimes it can be unclear that we follow this vision but over the years we 
are delivering this vision and we will continue. In this talk I will briefly 
recall the vision behind Pharo and show the achievements so far. I will show 
that our development is heavily backed by tests.
In the second part of the talk I will focus on the current effort to improve 
the user interface. I will show that the reimplementation of the Spec UI 
framework is a cornerstone of the future replacement of Morphic and use of GTK.
I will also answer questions about Pharo 11 and Pharo 12."

In general, all instance and indexable variables are processed.
Overwrite when necessary. Not used when #stonContainSubObjects returns 
false."

1 to: self class instSize do: [ :each |
self instVarAt: each put: (block value: (self instVarAt: each)) 
].
(self class isVariable and: [ self class isBytes not ])
ifTrue: [
1 to: self basicSize do: [ :each |
self basicAt: each put: (block value: (self 
basicAt: each)) ] ]

but I could not really get how to use it and if it was at the moment of 
writing. 
So I will patch my model but to me it defeats the purpose of serialization. 

Either we can serialize everything or we can transform to that we can fall back 
on the stable part. 
Forcing clients to prepare the objects to serialize is always possible but less 
satisfactory.
Because I will have to do it twice. to save 
from sorted to ordered 
save
from ordered to sorted

and on load 
from ordered to sorted.

I read 

writeObject: anObject
| instanceVariableNames |
(instanceVariableNames := anObject class stonAllInstVarNames) isEmpty
ifTrue: [ 
self writeObject: anObject do: [ self encodeMap: #() ] ]
ifFalse: [ 
self writeObject: anObject streamMap: [ :dictionary | 
instanceVariableNames do: [ :each | 
(anObject instVarNamed: each)
ifNotNil: [ :value | 
dictionary at: each 
asSymbol put: value ]
ifNil: [ 
anObject 
stonShouldWriteNilInstVars 
ifTrue: [ 
dictionary at: each asSymbol put: nil ] ] ] ] ]

It would be nice if we could say

MyClass >> transformedInstances
{
#series -> [:each | each asOrderedCollection ] .

}

Or something like that. I was considering to hack my own version of STON to 
avoid to that in my model. 
Or serializing nicely SortedCollection.

May be I missed something obvious.

[Pharo-users] STON little question

[stephane ducasse]

Hi Sven

I was using STON in P7 and I’m now migrating to P10.
In the past I had no problem with a SortedCollection and now I have because of 
the block serialisation (of course). 
So I cannot really ignore or skip my sorted collection because it has what I 
want. 
I could go over all my collections and transform them into OrderedCollection 
for the saving. 
But may be there is a hook for that.

In fact I do not care to save the sortedCollection as soon as when I reload I 
restore it.

[Pharo-users] Version of magritte for Pharo10

[stephane ducasse]

Hi 

I tried to load v3.7 in plain Pharo 10 and it breaks :(
I tried to load v3.8 and it breaks with the same error

Which version is supposed to work with P10?

[Pharo-users] Sponsoring our new mooc

[stephane ducasse]

Since more than a year we have been working on a new mooc called: “Advanced 
Object-oriented Design and Development”

It will be quite good. We are bullet proofing it with a new lecture here at 
Lille.
It will not focus on Pharo but on object-oriented design, tests, design 
patterns. 

It will present
- Test and test-driven 
- Essential aspects of OOP 
- Basic and universal principles 
- Double dispatch 
- Case studies in Pharo
- Some design patterns 
- Some coding idioms
and we will composed of 8 modules

Currently it has around 50 lectures and we expect around 60 + exercises.
You can access some drafts of the support here: 
https://rmod-files.lille.inria.fr/?dir=DesignCoffeeClub 


The production cost of this mooc is around 200 K Euros financed by Inria and it 
will be filmed in January.
We hope to deploy it in April or May 2023.
The mooc will be produced in english (and may be dub in french). 




It occurred to me in this difficult time to find good developers that some of 
you may want to sponsor this mooc\to get exposure.
You can be associated with some of the best OO teachers: me, Guillermo Polito 
and Pablo Tesone. 
We have cumulated more than 40 years of teaching experience. Several books...
Yes at the end of the day we should sale a bit our expertise - check below our 
track record with the previous mooc. 

As a sponsor you will get your logo and links on all the supports: Slides and 
videos.
Note that this mooc is designated to have a live time of 10 years or more. 
It is teaching fundamental points of OOP. 
So this is a unique opportunity to market your company to people wanted to 
learn advanced OOP 
Note that there are no other lectures like this one.

We have two levels of sponsoring:
2000 Euros for platinum sponsor
1000 Euros for plain sponsor

Let us know. 


Just a little reminder of the previous Mooc on Pharo. It has more than 8 years. 

For the record, some youtube videos (that we published after 4 years of running 
the pharo mooc) got more than 6000 views
and this is by developers. 

We got around 1 followers not counting the people watching the mooc 
on youtube and here are some of the testimonies we collected over the years.

[Pharo-users] Re: Porting from VW 8.3 to Pharo

[stephane ducasse]

Hi

If in the process you discover easy changes on the pharo side that 
can be either integrated in Pharo or packages from the Pharo side to help 
migration let us know. 
We would like to help but we are really really super full.
I tried to help to package values but I did not understand the process (I know 
the pharo way for sure to define baseline). 
Now a part of the team is really concentrated to improve the VM (we would like 
to have a 1.5 speed up) but 
it requires work and concentration. We are also working on permanent space and 
better memory management
thanks for lifeware sponsoring. 
Still let us know.

Shaping about the spec questions esteban is on vacation and when he will 
reappear he will check the libgit change impacting us. 
Then the spec aspects.

[Pharo-users] Pharo-vm mailing-list

[stephane ducasse]

Hi 

Since a couple of years the Pharo crew has been working on the Pharo-vm and 
most of the communication was using internal channels. 

Now that the community is growing we believe that it is important to have a 
public way to communicate around the VM and our current and future 
developments. 

We are happy to announce that we set up a mailing-list for the Pharo-vm.

[Pharo-users] ESUG deadline for Presentation

[stephane ducasse]

Hi Happy Smalltalkers

Two important points
- We are starting to work on the program of ESUG 2022 and we will 
accept some more talks 
but do not wait too long. 
https://esug.github.io/2022-Conference/call2022.html 


- The registration is open and the early rate is nicer than the late 
one :)
https://registration.esug.org 

But you can sponsor ESUG by registering with late fees from 6th of July.
But this is more expensive.

[Pharo-users] Re: [Esug-list] [PDFtalk] Porting to non-namespace Smalltalks

[stephane ducasse]

BTW about porting from VW, you see a friend of mine wanted to see how to help 
porting Siren to Pharo. 
Now this is not possible because he could not get a personal VW license. 

So even if people want to help pointing to a store database is equivalent to 
/dev/null for most people.
For example I cannot (and also does not for legal reason) run VW on my machine. 
Not talking about the new M1 I will get.

[Pharo-users] Re: Detecting keystrokes in Spec2 input fields

[stephane ducasse]

in general this is not a good style to set color directly.
Using style will make sure that your components will support themes in a 
simpler way. 
Because you will not have to have case statements and check all the place where 
you change color.

[Pharo-users] Re: [ANN] Pharo LZ4 Tools

[ducasse]

Yes this is a nice conversation. 
I know that marcus is working on slim binary. 
The idea is to compress but I forgot if it was bytecode or trees.

Now I wonder if the code text is worth compression.

[Pharo-users] Updates from the trenches...

[stephane ducasse]

Hello community

Just a little mail from holidays to let you know that from September on we will 
try a new organisation.

Pharo 9 (with Covid and amount of work) was stressful for us.
Seriously we deliver more than expected so we did several meta meetings (and we 
will continue) 
to understand how we can work with less stress. 
In particular we want to be able to give better feedback to the community while 
being able to deliver
the large items we have on our plate.

In a nutshell every month we will have

- a full working day around 
- design ideas such as

https://github.com/pharo-project/pharo/wiki/01-PhIP-Simplify-Pragma-Storage
- new tools such as MethodProxies to look at our lovely system 
in different ways
https://github.com/pharo-contributions/MethodProxies
- code review

- a full internal bug/issue internal sprint
we want to be able to concentrate on issues that require 
concentration
and we want to make sure that we can provide feedback and 
integrate PRs that need brain.

- our monthly open sprint (we hope that Covid 4th wave will not break 
our fun once again).

[Pharo-users] Re: Rounding in Floats

[ducasse]

Richard

As I said it thousands of times, 
- first we are not good in math
- second Pharo is what we have and we never said that it is the best 
system ever
we just enhanced daily
- third, I never saw a piece of code from you. 
- if you want to see Pharo improve (which I doubt about) just send us 
code and tests

I’m sad that you systematically ignore any of my emails on the topic. 
You could have an impact but you prefer to hide yourselves in your tower. Good 
luck with it.

[Pharo-users] Re: And it goes on - How do I fix a missing repository

[Stéphane Ducasse]

To fix a missing repo you follow iceberg you click on the repair menu item of 
the project.
Iceberg will then propose some several different ways (explained) and sorted by 
order of probability that they will solve your problem.
So if you select clone iceberg will clone pharo on your local machine.

good to know. 
Now we prefer to work with the slow version (old OS) because they kick us to 
pay attention to speed. 
Pharo 90 got many speed up improvements too.

I do not get what is the error. 
Do you have a script to reproduce it. 
We can only fix what we can reproduce.

David 

There is no magic. 
You should also consider that pharo-ui is a shell script and that you can also 
read it and learn. 
The vm is an executable and it needs an image and it cannot guess where you put 
it.

This is cool that you added some tests.
