Re: [Pharo-dev] How to use the serial port on MacOS X?

[olivier auverlot]

Hi Ben,

I don't think that the problem concerns the USB port or the cable because:

* I have tested with a simple Perl script (with the Device::SerialPort
module) and all is ok.
* In a shell, I can activate the rx/tx leds of the Arduino with the
command "more
-f /dev/cu.usbmodel1411".
* I can use the Arduino IDE to program the card and send my binaries.

If my Pharo code is correct, I suspect a problem in the serial plugin for
MacOS X. I tried unsuccessful with Pharo 5 and Pharo 6.

Best regards
Olivier :)

[Pharo-dev] 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

[Pharo-dev] Using Pharo with Debian 8 64 bits

[olivier auverlot]

Hi,

I just tried to use Pharo 4 in graphical mode with Debian Jessy 64 bits.
The last version of this Linux distribution needs some operations to
running Pharo. I think that could be interesting to share my configuration
work.

- unzip the Pharo4 archive,

- sudo dpkg --add-architecture i386
- sudo apt-get update
- sudo apt-get install ia32-libs

and now, the voodoo operations :-)

- apt-get install libx11-6:386
- apt-get install libgl1-mesa-glx:i386
- apt-get install libfontconfig1:i386

Hope that's can help someone.

Re: [Pharo-dev] Prepared Statements on PostgresV2?

[olivier auverlot]

Supporting open source database is the first step but you're right, we must
also propose a solution for proprietary databases. The difficulty is to
create an framework that proposes the ability to mix native driver (as
level 4 in JDBC) and driver wrappers for undocumented protocols.

As you, I'm a big fan of MSQL Server but keeps secret this information ;-)

Olivier

 Hi Olivier,

 Native driver in Pharo is good news :)

 Lack of Sql server support is bad news (I invested a lot in it for a long
 time, and I'm a fan)
 but I'll go for postgresql, I think I should like it too,
 I created a table once and did a select with it (haha)

 Developping the database protocols in Pharo is simply the best solution
 because Pharo is a cross-plateforms solution and it's necessary to have
 cross-plateforms frameworks for it. This solution will facilitate the
 deploiement of Pharo solutions because no configuration must be doing on
 the hosts. The Pharo image must be simply be copied.

 But yes it's a big work and I think that the priorities must be done on
 some databases servers as MySQL, Postgresql and SQLite. In the open
 source world, the protocols are more accessibles and the communities can
 help us.

   Did you port it to Pharo?

 I spend about a day evaluating it in 40272.
 I looked at three packages (and their two test packages).

 PostgresV3-Core handles the V3 protocol, makes a connection
 using a socket, provides a result set with rows, columns and
 text converters.

 I got a few problems in the unit tests, looks like something in the
 way floats are handled is different
 (PG3SocketReadStreamparseFloatLength:
 and there is a method missing PG3SocketReadStream
 parseScaledDecimal

 PostgresV3-Pool provides a connection pool.

 I was able to use that to connect to a database, execute queries
 and get
 data out of it. Issues there are trivial:

 PG3Connectionmd5HashMessage: aString

 ^Smalltalk globals
 at: #MD5
 ifPresent: [ :md5 | (md5 hashMessage: aString) hex asLowercase ]
 ifAbsent: [ WebUtils md5Digest: aString ]

 We don't have WebUtils, but we have MD5

 Then there is PostgresV3-CodeMirror.

 In PG3SchemaMirror there are some overrides to select a different
 compiler (+parser) and code highlighter. That allows subclasses
 to have plsql functions as methods, using the PG3FunctionMirror.

 In Pharo, I couldn't easily find how to change the
 code highlighter in Nautilus.



 The PG3Compiler just changes the parser used to PG3Parser.
 The PG3Parser is a subclass from the squeak parser and so uses
 some things that work a bit different
 PG3ParsercheckSyntaxFor: uses a cue instance variable. It is not
 a full plsql parser, relying on the
 database to check syntax.

 PG3SchemaChanges uses Toolbuilder to show a window with the
 differences between the functions in the
 database and those in the image and select which ones to change.

[Pharo-dev] PNG in Artefact

I improved Artefact this morning and added the support for PNG files. It's

In fact, the PNG is converted to JPEG image before to be included in the

someone have perhaps an idea to fix it.

 Thanks - but that was not my question. PNG graphics format can - but must

Re: [Pharo-dev] Prepared Statements on PostgresV2?

SQL support is very poor in Pharo and many improvements are necessary.
PostgresV2 is actually probably the best solution available because it is
written only in Pharo and works on many platforms. The framework does the
work but it's a limited solution.

 While it works good, it is missing a very important feature from both
 security and performance point of view: The prepared statements.

 As a brief, prepared statements are parameterized SQL statements that are
 loaded ONCE per connection instead of sending the whole query to DB every
 time, and also, they are parameterized, so it completelly prevents SQL
 injection, as the parameters are automatically 'detected' and scaped
 and/or
 handled accordingly without allowing in any case a parameter to alter the
 SQL meaning, which can happen by using regular SQL queries made by string
 concatenation.

 I browsed the class and did not find any prepare: method nor anything
 similar.

 Also, you can give a name to a SQL sentence, which makes the code much
 more
 readable without messing too much logic with SQL commands and string
 concatenation.

 An example is as follows: (supposing we have an instance variable
 connection, already initialized and connected via PGConnection class)

 Instead of:

 self connection execute: 'SELECT data FROM mytable WHERE name=''', anUser
 userName, ''';'.

 Would be something like this:
 self connection executePrepared: 'getUserData' with: anUser userName.

 And another suggestion could be something like:
 self connection prepare: 'getUserData' withSQL: 'SELECT data FROM mytable
 WHERE name=$1'

 Any plan for this to be implemented or any hint to other PostgreSQL class
 that already has it?

 David.

[Pharo-dev] Voyage,Mongo and Seaside...

[olivier auverlot]

Where must i initialize a mongo connection in a Seaside application when I
use Voyage ?

My application use the singleton mode of Voyage.  What is the good place to
create the singleton ?
  * in the initialize class method of mySeaside root WAComponent (It will
called one time when Seaside initialize the hosted applications)
  * in the instance method initialize of my Seaside root WAComponent (It
will called each time that's a user start to use the application)

The second case seems to be better because the connection time is probably
limited by Mongo or the connection could be broken.

Someone have experimented good practices at this problematic ?

Re: [Pharo-dev] ANNC: QR Code (v.2)

[Olivier Auverlot]

Le 7 oct. 2014 à 13:54, J.F. Rick a écrit :

 Well, the QRCode natively just has a bitmap form. The little server app 
 requests that form (perhaps with a border, mirrored, reversed, etc.) and then 
 magnifies it and converts it to a PNG. So, putting the result in a PDF is as 
 trivial or as hard as putting a bitmap form into a PDF. How difficult that is 
 is something that Olivier can perhaps answer.

In fact, the faster approach is to convert the PNG to a JPEG picture with Pharo 
and to include it into a PDF Document with Artefact. It's easy to do but I 
can't estimate the quality lost of the picture (I suppose that's is important 
for the scanning of the QRCode with a phone).

pharoByExampleLogo := (ZnClient new
url: 'http://pharobyexample.org/pictures/pbe-title.jpg';
get).
aPage := PDFPage new.
aPage add: (PDFJpegElement from: 5 mm@0mm wh: 160mm@90mm fromStream: 
pharoByExampleLogo readStream).

The best solution is to create a QRCodeComponent in Artefact and draw the 
QRCode directly in the PDF document.

 Make sure that everything work well and suits your needs.
 I'm not sure that current design is good. At least when olivier auverlot 
 showed to me I was skeptical about the chapter we/he wrote
 on it.
 In addition ... as far as I can see the current package is Pharo only (was 
 Squeak).
 If Pharo-only is o.k. I could for instance integrate my stuff for 
 LDAP-over-SSL in there directly (based on Zodiac).
 Excellent idea.
 Our goal is to make sure that people can make business.

Hi Guido,

You can try Faster than Light. This is a  pool connection to open
multiple sockets. The project is on Smalltalkhub (
http://smalltalkhub.com/#!/~RMoD/FasterThanLight). It works with Pharo 2.0,
not tested with 3.0

 Hi guys,

 Does anyone know about an open pharo app that make heavy use of sockets

 serious experiments? Something with heavy used of files will help too.

Re: [Pharo-dev] [ANN] PunQLite - a new NoSQL wrapper for Pharo

[olivier auverlot]

Really cool. That seems very simple to use :-)


2013/12/24 Masashi UMEZAWA masashi.umez...@gmail.com

 Hi all,

 I've developed PunQLite. UnQLite NoSQL database binding for Pharo.
 https://github.com/mumez/PunQLite
 http://smalltalkhub.com/#!/~MasashiUmezawa/PunQLite

 UnQLite is a fast, lightweight, portable, embedded KVS with a simple
 scripting engine (Jx9).
 http://unqlite.org/

 Torsen kindly wrote about PunQLite project's beginning on his blog.
 http://astares.blogspot.jp/2013/11/punqlite-for-pharo-using-unqlite.html

 At that time, it was only a bare NativeBoost FFI interface. Now it has
 become a full-fledged wrapper.

 db := PqDatabase open: 'test.db'.
 db at: 'Smalltalk' put: 'COOL'.
 db at: 'Pharo' put: 'HOT'.
 db at: 'Smalltalk' ifPresent: [:data |
 data asString inspect
 ].
 Transcript cr; show: db keys.
 db do: [:cursor |
 Transcript cr; show: cursor currentStringKey; space; show: cursor
 currentStringValue.
 ].
 db close.

 Moreover, it is quite fast. I wrote a simple benchmark that does many
 round-trips (put/get 10 small elements). The result is 877 msecs
 (on my windows laptop). It was impressive.

 Enjoy!

[Pharo-dev] New project announcement: PROXimity

[Olivier Auverlot]

Hi,

I just started since 3 days to work on a new framework for Pharo. It's named 
PROXimity. The goal of this framework is to control a Proxmox virtualization 
solution with Pharo. 

Proxmox uses a REST API. With Zinc and STON, it's very easy to give orders as 
creating a virtual machine, managing the boot and stop, etc. 

I'm working on this project  because it is a subpart of another application but 
I think that it could interest other Pharo users (for example: seaside hosting).

The first Pharo classes are published on SmalltalkHub. If you're interested and 
want join your forces with me, don't hesitate to contact me.

Re: [Pharo-dev] New project announcement: PROXimity

[Olivier Auverlot]

why not ! it would be very cool to have an abstraction layer. The difficulty is 
to communicate with the virtualisation product. For Proxmox, it's easy because 
it uses HTTP but I don't know the other products.

Le 3 oct. 2013 à 10:05, Christophe Demarey a écrit :

 Hi Olivier,
 
 Cool.
 Do you think it is possible to do a more generic Cloud interface in Pharo?
 I mean an API agnostic to the used cloud manage (proxmox, cloudstack, 
 openstack, amazon)? There is a Java project called jclouds[1] that does that.
 It may be cool that other people can define more cloud providers.

 Hi Olivier, Hi Guillaume,
 
 I tried to load the new version 1.0 of artefact into a new Pharo 1.4 image 
 and have the following problems:
 
 1) Gofer new
 smalltalkhubUser: '' project: 'RMoD/Artefact';
 package: 'ConfigurationOfArtefact';
 load.
 my Gofer does not understand smalltalkhubUser:project:
 
 2) I loaded manually - ConfigurationOfArtefact load
 I got the following error:
 DuplicatedVariableError: stream is already defined in PDFImage
 
 Can you please check this?
 
 Sabine

 You can download it from: http://smalltalkhub.com/#!/~RMoD/Artefact
 
 Artefact is a framework to generate PDF documents. It is fully written in
 Smalltalk and doesn't require any native library. Artefact is light,
 platform independant and offer to users a high level of abstraction in
 order to easily creating PDF documents.
 
  * completely written in Smalltalk (and only Smalltalk),
  * complete freedom about the order of creation for pages, elements... (no
 need to follow the document order)
  * multi format and orientation for pages
  * page composition based on reusables PDF elements,
  * extensibility by offering a composition standard to create your own high
 level elements
  * styleSheet that can be reused in many documents and avoid wasting time
 and place with duplication
  * image support with the JPEG format
  * pre-defined high level elements like datagrid
  * support PDF compression to produce compact files
 
 A basic documentation is available in the help browser. Many examples are
 implemented in the PDFDemos class.
