Re: [Pharo-users] Pharo and ActiveDirectory

[olivier auverlot]

Torsten,

I'm not sure that a Active Directory client protocol is available for
Pharo. We have only an LDAP framework (LDAPlayer) that runs fine (I use it
every day).

A quick solution is to use another language to build a REST service
(perhaps that a open source gateway is already available ?)  and
interfacing your Pharo app with him.

Best regards
Olivier :)

Hi Alejandro,

There are no activities in the Artefact project because it does what we
need. Of course, if you want explore the world of Unicode, you can do it.
We are interested :)

Re: [Pharo-users] PostgreSQL and Pharo 6

[olivier auverlot]

Hi Dimitris,

It's not a SSL problem. Normaly, you can use PostgreSQL without SSL. The
error message says that you must add your client device in the pg_hba.conf
file. This file lists all the devices that are authorized to connect to the
PostgreSQL server.

https://www.postgresql.org/docs/9.1/static/auth-pg-hba-conf.html

At work, I use the postgreSQL V2 protocol without problem with Pharo but I
have not yet tested with Pharo 6. With Garage, it's a cool solution to
build database applications.

Best regards
Olivier :)

[Pharo-users] How to use the serial port on MacOS X?

[olivier auverlot]

Hi,

I try to use the serial port to communicate with an Arduino. On Linux, no
problemo. I can open the serial port with the following code:

| serialPort baudRate comPortNumber |
baudRate := 31250.
  comPort := '/dev/ttyACM0'.

  serialPort := SerialPort new
baudRate: 31250;
   dataBits: 8;
   stopBitsType: 1;
   parityType: 0;
  yourself.

"the port is closed to ensure that it will be free"
serialPort close.
(serialPort openPort: comPort) isNil
ifTrue: [ ^self error: 'COM port not available' ]
ifFalse: [ serialPort inspect ].
serialPort close.

But on MacOS X (10.11.6), the same code used with /dev/cu.usbmodel1411
doesn't run. The error is "Cannot open '/dev/cu.usbmodel1411'". I'm sure
that is the correct serial port. If I type "more -f /dev/cu.usbmodel1411"
in a terminal, the rx/tx leds of the Arduino are blink.

Someone has an idea about this problem that is not specific of the Arduino
but concerns the generic usage of the serial port with Pharo?

Best regards
Olivier

ps: I can't test on Windows but I'm interested by a feedback.

Re: [Pharo-users] Arduino

For the moment, I just want to do a catalog of the existing solutions. The
next step will be to evaluate them.

My main target is a Firmata protocol implementation usable with Pharo 5 or
6.

[Pharo-users] Arduino

[olivier auverlot]

Hi,

Since some weeks, I do some experimentations with an Arduino board. I
search now to use my Arduino with Pharo. I have found some informations on
the web but nothing seems usable or up to date for the latest versions of
Pharo.

Someone have worked on this domain ? I'm interested by a firmata client
protocol or why not a solution to program an Arduino directly from Pharo.

Best regards
Olivier ;-)

Re: [Pharo-users] Create png from pdf

[olivier auverlot]

Hi Sabine,

Converting a PDF into a PNG with Pharo is not an easy task because you must
write a PDF reader.

With Artefact, the other approach is to draw on a form instead of
generating the PDF instructions. For geometrics items, It's relatively easy
but the respect of paper formats and the management of fonts could be very
complex.

The difficulty is to have the same result between the PDF document and the
simulated document  written in a PNG file.

Best regards
Olivier

Re: [Pharo-users] Dues anybody try Artifact with non latin characters?

[olivier auverlot]

Denis,

Could you publish a snippet of code that generates a PDF document with a
text that contains russians letters ? We need to test.

For russian letters, I think That You need a consistent font and the proper
encoding. Normally, the Helvetica / Arial  should be ok. For the encoding,
the standard fonts use ISO-8859-1 or windows-1252. If you use UTF8, You
Could try to convert your text to this encoding before insert it in the PDF
document.

Re: [Pharo-users] How do I run Pharo on Debian?

[olivier auverlot]

On debian 32 bits, the standard version works very well. Just unzip the

Re: [Pharo-users] Artifact

[olivier auverlot]

Hi Hilaire,

I just tried the stable version of Artefact in a Pharo 3.0 image. All demos
are ok but I uses Mac OS X.

Could you test with Acrobat Reader  on Linux? The PDF reader (Evince ?) has
a lack of functionalities and it's not a good thing to use it. Many PDF
specifications are not or bad supported. The situation are the same that
with browsers and the support of HTML. Only Acrobat Reader can be
considered as validation tool.

Best regards
Olivier ;-)

very interesting :-)

2015-05-09 21:13 GMT+02:00 Attila Magyar m.magy...@gmail.com:

 Hello,

 Teapot 0.91 released today.

 Teapot is micro web framework that focuses on simplicity and ease of use.

 Here's a summary of changes:
  - Routes and before/after filters may include conditions (see the example
 below)
  - Routes can be defined with /any:/ that serves as a wildcard matching any
 http method
  - Added /charSet:/ accessor to TeaResponse

 E.g.

 Teapot on
 GET: 'test' - result; when: [:req | req accept = 'application/json'];
 start.

 Hi all,

 A time ago i posted two board games on the list and Stéphane said that he
 would like to extract from these and other ones he has gathered a framework
 for doing board games. So i developed a little one called 'Boardician' and
 implemented four little example games through it.

 DOCUMENTATION
 http://boardician.blogspot.com.ar/2015/03/boardician.html

 DOWNLOAD https://www.blogger.com/null
 You can install configuration BgBoardician from Configuration Browser on
 3.0 and 4.0 . This will download packages of framework (BgBoardician) and
 example games (BgBoxPush, BgEatBullet, BgDropPiece, BgEatElongating)

 To run example games send

 EDirector new play.
 BPDirector new play.
 DPDirector new play.
 GDirector new play.


 FEEDBACK https://www.blogger.com/null
 If you like (i would really like you to) to send any feedback comments on
 design / names / implementation / functionalities to add / questions you
 can post a comment on the blog / mail me.

 Next i'll be adding tests and uploading development history to project's
 repo.

 Best,
 Laura

[Pharo-users] Pharo and ODBC

[olivier auverlot]

Hi,

I try to use the ODBC framework presents in the configurations list and

I want connect Pharo to a Postgresql server and I installed the latest

datasource. The connection test is ok. My computer uses Windows 7 64 bits.

In Pharo, I try to connect with the following code:

connection := ODBCConnection dsn: 'mysource' user: 'myuser' password:
'mypassword'.
connection close.

The connection fails and I get an error message: The data source (DSN) has

solution ?

  Hi,
 
  I'm using Voyage in a Pharo application.
 
  I have two MongoDB collections which are ComicsCollection and

 reference of each book is stored in an ordered collection (in the instance

  How can I remove properly a book and the reference to the book ?
 
  From the smalltalk image view the problem is usually exactly the
 opposite: You don’t delete objects but you remove references to them. As
 voyage maps objects it is a good idea to stay in the object realm. So you
 should rather remove the book from the collection. This way you won’t get
 errors just garbage. The „real“ problem that arises then is that the book
 would still be in the database. Just like it is in the image but there is
 no garbage collector for mongo. To decide that from the image is not
 possible. You load only a sub graph from the database into image memory. So
 you don’t know if there are other objects referencing the book.

 If your records fit all in memory you could load all collections and
 books and build the difference between all referenced books in the
 collections and the total amount of books. The difference will be the set
 of objects not being referenced by a collection and those can be deleted.

 If the records do not fit in memory an alternative strategy would be
 needed. I started to research if it is possible to build a map/reduce based
 garbage collector for common cases but got distracted. But I have the same
 problem so I will need to pick it up some time.

 hope that helps,

  If you need a shallow copy then you better just copy the object and
 store it. Changing the id is asking for trouble I guess. That would
 probably work if you implement #= on those objects but I think it is a hack.
 
  anObject copy save

 But Olivier's problem is that he is talking to a server that does not do 
 proper percent decoding, IMHO. A server parsing a URL should resolve all 
 percent encodings, after parsing using the significant delimiters (/ : ? #).
 
 http://foo.com/abc and http://foo.com/%61%62%63 are the same thing, just like 
 http://foo.com/abc@1 and http://foo.com/abc%401 are - again as far as I 
 understand it.
 
 That being said, I am going to study the specs again and might change what 
 gets encoded or not depending on the URL element, instead of encoding 
 aggressively in the better safe than sorry way.
 
 Olivier's suggestion about safer authorisation parsing does make sense and 
 will get added as well - Thanks Olivier !

[Pharo-users] Zinc: How to use the @ character in an URL

[Olivier Auverlot]

Hi,

I work actually on a framework to manage a Proxmox server. The Proxmox solution 
is based on a strange REST API… :-(

To get informations about an user, I must send a string with the login and the 
authentication domain. The two values are separated by a character @. 

For example: GET /api2/extjs/access/users/auverlot@LIFL

My first problem with Zinc is that the client find the character @ and the 
client think that this is an URL with authentication. I tried to use an 
encoding string with %40 but Proxmox don't find the user.

The solution must be to modify the method ZnUrl#parseAuthority:from:to: to do 
a better detection of authentication pattern:

parseAuthority: string from: start to: stop
| index  |

index := string indexOf: $@ startingAt: start.

(index  0 and: [ (string indexOf: $: startingAt: start)  index and: [ 
index  (string indexOf: $/ startingAt: start) ] ])
ifTrue: [  
self parseUserInfo: (ReadStream on: string from: start 
to: index - 1).
self parseHostPort: (ReadStream on: string from: index  
 1 to: stop ) 
]
ifFalse: [  self parseHostPort: (ReadStream on: string from: 
start to: stop ) ] 

But, it's not the end of the road :-( Because in the next steps, Zinc encodes 
the character @ in the url.  How to disabled the automatic encoding and using 
special characters in the url ?

Thanks for your help.

Best regards
Olivier ;-)
