If I change Float to Object, all get back to normal.

Why is it like this ?

Re: [Pharo-users] Problem due to deprecation of class Url in Pharo 3 and Moose 5.0

[stepharo]

Yes change the code of the Parser not to use old code.

As I pointed out, the Parser is a large and complex package, and I am not
the author, so this is easier said than done.

I'm dealing daily with code having the same characteristics.


It seems a bit odd to dismiss
code which worked OK in Moose 4.9, but not in Moose 5.0, as 'old code.'


I do not know what happened between 4.9 and 5.0 but if this is between 
pharo30 and pharo40 => one full year of efforts (you know
many people improving things and putting energy in the system). And be 
ready because we will remove URL old class.
Now the good aspect is that you are lucky (we are all lucky) that sven 
is improving constantly Zinc.


But there is no such world were unmaintained packages would 
indefinitively work while the world is changing.

  It
is code which has no functional equivalent in the new code, as Sven has
confirmed.

Then it means that you have to cooperate with sven to get Zinc improved.
And feel lucky you can.

The overall process may look frustrating but a system that is not 
changing is

adapted or it becomes progressively less satisfactory[3]

Hello
  
I have run into a problem in moving some existing work from earlier

versions of Pharo/Moose. I have found a work around, but I wonder if there
is a tidier way of handling it.
  
I make frequent use of Todd Blanchard’s HTML parser and validator, HTMCSS

(http://smalltalkhub.com/#!/~ToddBlanchard/HTMCSSValidatingParser), which
was originally written for Squeak but has performed without trouble on
earlier versions of Pharo. When I try to use it on Moose 5.0, I get frequent
warning messages about Url being deprecated. I have made the problem go away
by commenting out the deprecation warning in Url class>>new, but I wonder
what should be done on a more permanent basis.

Yes change the code of the Parser not to use old code.

The problem arises because HTMCSS does not just parse the original HTML

file; it also loads and parses any referenced CSS files. (This is a function
I could do without, but I don’t fancy trying surgery on a complex package
where I only partly understand the workings!) It constructs the full address
of the CSS file by combining the root address of the HTML with the relative
address of the CSS, using Url class>>combine:withRelative:, and in the
course of this it invokes Url class>>new; hence the deprecation message.

use ZnURL

The deprecation message says Url has been replaced by ZnUrl, but this is

clearly  not a simple replacement of one message by an equivalent; there is
no ZnUrl class>>combine:withRelative:, for instance.

Sven will certainly comment but I guess that there is certainly the same

behavior.

ZnUrl>>#inContextOf: is the selector you are looking for, but path merging
is not supported (yet).

'readme.txt' asZnUrl inContextOf: 'http://www.host.com:8080' asZnUrl.

Maybe we should add path merging, I'll think about it.


The tidiest solution would no doubt be to find an equivalent method in

Zinc, which I am sure exists, and then modify the HTMCSS code to use it. I
have tried to find an equivalent, but Zinc is a large and complex system and
I rapidly got lost.

It should be in ZnURL

is it not addPathSegment:?


from class comment

   ZnUrl new
 scheme: #https;
 host: 'encrypted.google.com';
 addPathSegment: 'search';
 queryAt: 'q' put: 'Smalltalk';
 yourself.
   
host: looks like the root

addPathSegment: looks like https://encrypted.google.com/search

  
I wonder more broadly about the strategy of deprecating functions which

are required by legacy packages, as in this case. Should there at least be a
way of overriding deprecations? (I suppose that is what I have done by
commenting it out, but it seems crude.)

This is how you can work around Deprecation warnings:

[ Url combine: 'http://www.foo.com/one/two/' withRelative: 'bar/readme.txt'
]
   on: Deprecation do: [ :exception | exception resume ]

but that is a temporary hack.


Thanks in advance for any help or suggestions.

Ah, I just saw on second reading that you want to implement something

There are more arguments against Subclassing any Number class:

Exchange rates are two-way most of the times. It is not only USD->EUR,

Thanks for the tips.
I saw the Unit package was following the same pattern you are describing.

Re: [Pharo-users] How to subclass Float class

[Hilaire]

Very interesting reading.

The formula in figure 1 is wrong as it is "composed" interest, and power
should be used.

rate := 10 % / 1 year
terms := 6 months

100$ * (1 + rate) ^ terms

So I wonder how the simplification as exposed in Fig. 4 goes in that
case (rate should be transformed to 10/1200) and would be really
interested if the model can fit the real situation: how the model can
deduce rate per year should be adapted to rate per month without a prior
knowledge of the formula meaning.

In Smalltalkhub I see two Acomcagua packages, which one to use?

So, what I'm planing for this year:

1. To learn/teach more about Pharo specially moldable tools, fluid 
interfaces and good devel practices.
1. To have a good application with some data narratives and

clean code instead of the rookie one I have now.
2. To create a stronger local community around data 
visualization/narratives for Open/Garage/Citizen Sciecen & Research

3. To write more.
4. Economical contributions to the community through the association.
5. Hopefully make stronger ties to the international community in South

Re: [Pharo-users] if Pharo is key for you

[kilon alios]

Good thread I would love also to hear what other Pharoers work behind the
scenes

My own project is Ephestos a visual coding enviroment for Blender . I have
made some good progress in 2014 and I am sure 2015 will bring more
features. Ephestos will benefit the Pharo community by

1) Offering full access to the most powerful open source and free
application for creating of 3d art , Blender.

2) Allow Pharo full access to Cpython libraries one of the most popular and
powerful language out there and also allow python code to mix with pharo ,
see python code as pharo code etc.

Both goals have been achieved partly and I hope to bring my project closer
to them each year.

https://www.youtube.com/watch?v=XPGDQc5LUvE

I am also interested as secondary goals to

3) bring more visual coding tools to pharo

4) integrate tablets and smartphones (android and ios) with pharo as
external controllers and as replacements to both mouse and keyboard.

Re: [Pharo-users] Metacello does not load the expected version from ConfigOf

[Dale Henrichs]

Usman,

Well I don't have an official bugfix yet, but if you filein the attached 
method and run the following, PetitParser will downgrade and get loaded 
correctly (at least it worked for me)...The fist two statements are 
intended to replace GTMetacelloPlatform with MetacelloPharo30Platform 
and initialize the registry correctly ... not sure what impact on Moose 
these changes will have) :


MetacelloPharo30Platform initialize.
  [
  MetacelloProjectRegistration
resetRegistry;
primeRegistryFromImage ]
on: Warning
do: [ :ex |
  Transcript
cr;
show: 'Warning resumed: ' , ex description.
  ex resume ].
Metacello new
configuration: 'DummyParser';
version: '1.0';
repository: '???';
onDowngrade: [:ex :existing :new |
existing projectName = 'PetitParser'
ifTrue: [
new projectSpec operator: #=.
ex allow ]
ifFalse: [ ex disallow ] ]  ;
load.

The new method will be part of the next Metacello release and has been 
tested[1], but I may take a slightly different approach with the 
official bugfix. Setting the operator achieves the desired result, but 
is not quite how I would like to address the issue.

something here?

Good question, I don't have a lot of time today to spend time
trying to reproduce your problem, but if you send me a copy
of the Transcript produced while doing the load I might be
able to spot the problem ...


It looks to me that the downgrade command is not working.
Whenever I point to the version preceding the one loaded, the
packages are not fetched.

I am attaching here two files.

The first (Transcript-PP151) is the output of the transcript as
you asked. You can see that PetitParser packages as defined by
the version 1.51 are not fetched. All that is loaded is Glamour
because the version 1.51 of PetitParser loads the latest packages
of Glamour. The load works because it is an upgrade from the
current version of Glamour which is a stable.

When I saw that only Glamour packages are loaded, I thought of
testing Glamour downgrade too to see if the problem is specific
to PetitParser. You can see the result in the second file
(Transcript-downgrade-glamour). No packages of Glamour are
fetched because the configuration tries to downgrade it (stable
is more recent than 3.0.0 which I try to load).

In my opinion, downgrade is not working as required. If you want
I can share my image thru dropbox so that you can have a look to

4. Read a lot of previous email to be aware the community memory and 
revive older threads when is possible and trying to be a more 
proactive/visible member of this community, even in my newbie condition.


So, what I'm planing for this year:

1. To learn/teach more about Pharo specially moldable tools, fluid 
interfaces and good devel practices.
1. To have a good application with some data narratives and 
visualization build on it. A good download page, documentation and 
with clean code instead of the rookie one I have now.
2. To create a stronger local community around data 
visualization/narratives for Open/Garage/Citizen Sciecen & Research 
powered by Pharo.

3. To write more.
4. Economical contributions to the community through the association.
5. Hopefully make stronger ties to the international community in 
South America or Europe by participating in some event or scholarship 
(this will depend on costs).


Thanks for the questions and I will be glad to read other 
answers/prospective about persons and Pharo,


Cheers,

Offray

super!
It is always good to do retrospective analysis to see what we learned
and it looks like you learned a lot.
If you need pharo slides let me know.

Hi all,

Just picking up some old threads, so I answer this below.

Hi guys

if Pharo is key for you then you should ask yourself what you did for
Pharo recently.
Writing code, writing documentation helping closing bug entries,
participating to the association, to the consortium...

Pharo is not happening from spontaneous generation.

Well I recently (previous semester) start to:

1. Learn Pharo.
2. Develop my own app to learn and write about the process [a][b]. I
will be payed for this prototype and will be a paying member of the
association.
3. Made my local group of Pharo/Smalltalk on Data narratives and
visualization for Open/Garage/Citizen Science & Research at our local
hackerspace with several (3 or 4) meetings that will continue this
year [c].
4. Read a lot of previous email to be aware the community memory and
revive older threads when is possible and trying to be a more
proactive/visible member of this community, even in my newbie condition.
