New book for Pharo :)

Didier Besset offered his great book "Object-Oriented Implementation of
Numerical Methods
An Introduction with Smalltalk and Java" to the community.

We would like to thank Didier Besset for his great book and for his gift
of the source and implementation to the community.

You can find
• Archive of the original book, with code in both Java and
Smalltalk
https://github.com/SquareBracketAssociates/ArchiveOONumericalMethods

https://github.com/SquareBracketAssociates/ArchiveOONumericalMethods/blob/master/NumericalMethods/2015-Jan-WholeBookST-Java.pdf

• An abridged version of Didier’s book, without the Java
implementation and reference; our goal is to make the book slimmer and
easier to read. The implementation presented in this book is part of the
SciSmalltalk library.

https://github.com/SquareBracketAssociates/NumericalMethods

https://github.com/SquareBracketAssociates/NumericalMethods/blob/master/2015-Jan-WholeBook.pdf

• SciSmalltalk library https://github.com/SergeStinckwich/SciSmalltalk.

Both book versions are maintained by St ́ephane Ducasse and Serge
Stinckwich.

I do not know NumericalMethods. I vaguely recall that you were no happy that serge wants to change the code
because it would not be in sync with the book. Now we can co-evolve them.
Every I do is open-source and freely accessible so position yourself and join effort (I do not like SciSmalltalk as a name).
Now we have the possibility to make on nice library but you need to sync.

I am trying to avoid what the Python community did with NumPy and SciPy which is a mess.

Ah you see you have to sync with Serge. I think that Serge was not aware about that you publish the code in your repository.
Now we want to rename the acronym (because DHB is not good) and probably improve the code
of the library while keeping the book in sync (like using String streamContents for printing).
I personally hate to see all the comment with a copyright and a commit dates.

No idea what the problem really is, and what is that "mess" that concerns Numpy/SciPy but I welcome the new book , more documentation is always a cause of celebration, thank you for your hard work :)

Way cooler than SciPy if you ask me ;)

We have to get better at communication. It doesn't work if all of us fork libraries.

Let's get started with this.

I agree with NumericalMethods being freezed in the Configuration Browser.

But I don't want to be forced to load the whole SciSmalltalk to use 3 methods in NumericalMethods.

Do you agree Serge?

Can you import the ConfigurationOfNumericalMethod from a common repository in SciSmalltalk?

Hi Hernán,

>We have to get better at communication. It doesn't work if all of us
fork libraries.

i guess i disagree, the occasional fork <g> can be freshening.

>But I don't want to be forced to load the whole SciSmalltalk to use 3
methods in NumericalMethods.

that's not really necessary. assuming that you want to also use the
dhb-extensions, you can eg do something like:
(ConfigurationOfSciSmalltalk project version:#stable)load:
#('Math-DHB-NumericalExtensions' 'Math-Tests-DHB-Numerical'). "a
MetacelloFetchingMCSpecLoader(linear load :
linear load : 0.16 [ConfigurationOfSciSmalltalk]
linear load : 1.0 [ConfigurationOfArbitraryPrecisionFloat]
load : ArbitraryPrecisionFloat-nice.38
load : ArbitraryPrecisionFloatTests-nice.16
load : ExtendedNumberParser-nice.1
load : Math-DHB-Numerical-wernerkassens.30
load : Math-Tests-DHB-Numerical-wernerkassens.9
load : Math-DHB-NumericalExtensions-WernerKassens.5)"
this loads additionally ArbitraryPrecisionFloat, but this is, i'd say,
an unimportant bug in the config, that should get repaired occasionally.
and ArbitraryPrecisionFloat is not that big. it's not really a problem.

>Can you import the ConfigurationOfNumericalMethod from a common
repository in SciSmalltalk?

there could eventually be a little difficulty. you cant load both
versions. of course one could work around that problem in the config, but
1. the config of scismalltalk is already complicated enough, that hardly
anyone changing it can get things right there at their first attempt.
2.it would also complicate the _use_ of the config for the user, a big
drawback imo.
of course one could simply throw away the fork. but then one would need
to throw away also some other packages.
a third possibility would be to put all changes in the fork in an extra
package that can be loaded on top of the original dhb. but that looks
like a sizable enough task, that i at least will not do it.

what do you think?

Thank you for the tip. But that also means now I should change my configurations to stay updated because you (doesn't matter who) just couldn't resist copying all NumericalMethods packages to your own repository.

This is like if I get 5 mathematicians, fork SciSmalltalk, push cool new features, and then make all you loose them if you don't update. And I could do it for fun 1000 times. You get the idea.

But I am not against SciSmalltalk, I don't like forks without a good reason.

"a MetacelloFetchingMCSpecLoader(linear load :
linear load : 0.16 [ConfigurationOfSciSmalltalk]
linear load : 1.0 [ConfigurationOfArbitraryPrecisionFloat]
load : ArbitraryPrecisionFloat-nice.38

>Can you import the ConfigurationOfNumericalMethod from a common repository in SciSmalltalk?

I am saying there should be one version.

of course one could work around that problem in the config, but
1. the config of scismalltalk is already complicated enough, that hardly anyone changing it can get things right there at their first attempt.

Then the project is badly organized?
Because Metacello supposedly should help things to become easier.

2.it would also complicate the _use_ of the config for the user, a big drawback imo.
of course one could simply throw away the fork. but then one would need to throw away also some other packages.
a third possibility would be to put all changes in the fork in an extra package that can be loaded on top of the original dhb. but that looks like a sizable enough task, that i at least will not do it.

what do you think?

What's done is done. I doubt you could retract your changes.
I don't like this situation but it seems to be the Smalltalk way.

Re: New book for Pharo :)

We could probably start with

RBClassRegexRefactoring new
  renameClasses;
  replace: '^Dhb(.*)$' with: 'NM$1' ignoreCase: false;
  execute.

or whatever prefix you prefer :)

I wrote some DHB extensions for easier building of matrices,
if anyone give me access to the SciSmalltalk repository I could push them for review.
