Re: [Pharo-dev] The HiDPI Issue

[Markus Fritsche]

OT: Have a look at the „run_scaled“-script that uses xrpa.

I am using KDE5 (before that XFCE with a dpi setting of 192). Sometimes it 
resets scaling during a sleep, but it mostly works.

Re: [Pharo-dev] Any idea for a cool name for the remote tool suite?

[Markus Fritsche]

Hello,

I guess the vote is already cast, but I'd like to add my two Cents:

the packages now have a description that give an idea about what the 
package is supposed to do. Still, discoverability should be considered 
when finding a name. That's why I would prefer something like TelePharo, 
since the name already hints at the core functionality.


Best regards,
  Markus

[Pharo-dev] Ubuntu PPA administration - volunteers?

[Markus Fritsche]

Hello list,

I haven't been able to supply as many ppa updates as needed. Right now,
there's a need for a new spur vm and a new graph of dependencies between
the packages that I havent't yet set up.

Realistically, I think I won't be able to keep up as with pharo
development it deserves :(

Is there anyone whos willing to help? It involves
- setting up a build environment
- keeping up with pharo vm, pharo launcher releases
- executing build scripts
- react to errors - not that often
- entering your gpg key passphrase
- testing the successful deployment

Best regards

Hello Brad,

did you do this as posted to pharo-users?

If you're *not* using pillar or phratch, and have problems updating the pharo 
packages, please execute

dpkg -l | grep -i pharo | awk ' { print $2 } ' | xargs sudo apt-get -y
purge ; sudo apt-get update && sudo apt-get install pharo-launcher

"dpkg -l | grep -i pharo | awk ' { print $2 } '" will list all installed
pharo-packages, xargs will give that result to apt-get for the packages
to be purged (that is, remove all their data and metadata - the images
that you have in your home directory will NOT be affected).

Kind regards,
  Markus

Since the original created stable image, the dependencies have been

Hi,

the recent built pharo launcher didn't work - I had to delete the
package. Unfortunately, the ppa meta data seems not to be updated
accordingly. Until I have a new pharo-launcher, please download
https://launchpad.net/~pharo/+archive/ubuntu/unstable/+files/pharo-launcher_2014.11.30-2~ppa1~trusty1_all.deb
and install it manually.

There are some changes to the way the packages work that I need to sort

Hmm,

I uploaded my first updated VM to stable instead of unstable. Everything

I don't want to imply it's easy.

I once tried to decompose a squeak image, serialize the contents and
then try to create a new working environment from that. I finaly gave up
when I got { "One step forth", "Two steps forth", "One step back", "Two
steps back"}* in any number of combinations...

The image is a a) crafted artefact, not a b) generated one, but I think
pharo is on a good path from a => b.

GNU Smalltalk does just that, if it doesn't find an image, it will be
bootstrapped by using the shipped .st fileouts.

A bit of cheating is involved, a compiler & initialization is
implemented on the VM side.

So I would say "there are no Smalltalk that are able to do that right
now the way we want to do it" :-P

[Pharo-dev] Pharo Catalogue

Serge Stinckwich  wrote:

Something I already thought of a year ago or so. To put something on a 
scratchpad:

Tricky bit is to make it sustainable, packages are scattered because the 
community doesn't want to impose a way of working (which is legit). I would 
think a wiki-like catalogue, where authors can describe their solution/ code 
should be considered. That way, if someone doesn't care to describe, someone 
else could do it for him. 

The only link should be the name - no other meta data like versions and so on, 
since a package in the configuration browser should be pretty self contained.

Hosting must be closely tied to the Pharo infrastructure. I know from 
experience, if I was to setup something on my iron, I'd lose interest with a 
few quarters and it would develop into another "tried it, didn't work, can't 
shutoff, can't migrate away" sort of thing...

Thanks, but that was meant more general. 

If I fire up the Pharo Launcher and go to the configuration browser, I see 25 
offerings on the first page, of which roughly 50% (12) give me an idea what 
they're about. The other 13 - I really have no clue and need to google them ;-)

If I'm having a problem with the browser implementation, AltBrowser might be a 
thing to look at. If "SuperGemMiley" (which might also implement an alternative 
browser) is something I should look at, I will only find out if I google 
" pharo" and write down whatever comes up on github, smalltalkhub, 
jenkins... :-)

always hearing developers wanting 64-bits in their applications.


The only place I have found it to be a showstopper is with trying to 
interface libraries that are closed source and only distributed as a 
64bit version. Doesn't happen very often though.

If you're just going to use .xlsx files, it might be
possible to unzip
the file and peek the xml representation of that table (not
that I've
done it though).
  By unzip the file you actually see the xml,
  but I will complicated to use the values of the formula
  cells and to differentiate the sheets...

  

Yup - I don't know the excel xml format, just remembered that it
might be an option...

  

  
  
  If you're going to support .xls / Excel < 2003 files,
  you will probably
  need a COM-bridge. I remember that I've seen it
for Squeak in the past,
I don't recall having seen it for Pharo.
  It is only Excel
  > 2003.
  
  
  Another kind of hackish solution could be setting up an
  ODBC driver for
  Excel files and then using DBXTalk/ODBC or the
  ConfigurationOfODBC-based
  package.
  
 
I have tried. 
But when I launch
the DBXTalk tests it asked me to choose a
DBXODBX*Facility... Which one should I choose? 
  

  


here is how I connect to an access database on windows:

execute once per session:
OpenDBX current: NBPharoOpenDBX new.

then (access):

| aRow conn settings result |
settings := DBXConnectionSettings host: '<dsn name>'
  port: '' database: '<database filename>'
  userName: '' userPassword: ''.
conn := ((DBXConnection new settings: settings) platform:
  DBXOdbcBackend new) connect.
conn open.
result := conn execute: 'SELECT * FROM <table
name>'.
aRow := result nextRow.
[ aRow notNil ] whileTrue: [ 
    aRow values do: [ :value | Transcript show: value; show:
  $; ]. Transcript cr. aRow := result nextRow ].
conn close.
  
Everything in <> brackets needs to be replaced by actual
values. Also, the ODBC backend doesn't support many types =>
which will probably break too :-(

And you will need libopendbx-1.dll, libopendbxplus-1.dll and
opendbx\libodbcbackend-1.dll in your image directory. 

That all being said - before I'll dive into that, I would
probably just whip up a vba script to convert the excel
tables to text files in bulk.


  

  
Should I install
some plugins?
And in
ConfigurationOfODBC there is no tests and doc so I don't
know how to launch it...
  

  

I think there are tests in the monticello repository next to the
ODBC package (there's probably a script command to install them, but
I am usually faster just installing the package from Monticello
manually).

Kind regards

[Pharo-dev] [ANN] Transition of Ubuntu PPA maintenance

[Markus Fritsche]

Hello,

The maintenance of the Ubuntu Pharo VM and .source Packages is being
transferred from Damien Cassou to myself, Markus Fritsche. By trade, I
am a Business Intelligence consultant, but always following what's going
on with smalltalk/ pharo.

If you experience any problems with the ubuntu packages, please feel
free to contact me. I might not be able to help right away, but I'll try
my best!

Best regards,

Hello Norbert,

the ubuntu vm build is in the process of being switched from Damien

I will update the PPA asap.

Hello Eliot,

my first action if I look into something is to google and open tabs for 
the first three links that are not a mailing list (the latter I open 
when I search for a fix) - so maybe http://wiki.squeak.org/squeak/1414 
should be updated with links to your blog posts/ mailing list entries.


Also, the links for "FFI call DLL functions squeak" (which I would look 
for if I'm wrapping some C API dll) seem to be mostly outdated/ old. The 
FUD you criticize seems  to be more recent. As I do not understand the 
low level stuff of callout mechanisms (I can read an API and wrap calls 
to it and unwrap results though) I have to rely on what I find from an 
API user perspective, and I tend to think that information that has a 
more recent date on google is the "latest truth".

now, since the most common use of NB is for FFI, and NB is not present
in all platforms, we are working (Ronie, in this case) in a “unified
FFI”, which will provide a common abstraction layer for several FFI
frameworks (NB, OldFFI, Alien…). With that, we can choose which one
of the frameworks we use depending on the situation (but ideally, we
will maintain just one, the one that fits better in Pharo).


I feel that providing a common abstraction layer on top of the various 
approaches to interface to C/ C++ libraries won't be useful and should 
be considered a waste of resources. From what I understood from the 
documentation, NativeBoost seems to be the most complete interface 
technology yet. I would rather (as in: If I was capable) try to get 
NativeBoost into Squeak and add the functionality missing that still 
justifies the existence of FFI and Alien than creating an abstraction 
layer that can't cope with the differences in the tools (which was the 
reason for their first creation despite the available ones).


I tried to play around with FFI and creating plugins in Squeak and 
failed (I didn't try very hard though). NativeBoost was the first thing 
I was able to wrap a DLL myself and understand how to do it. The only 
thing that I wasn't able to wrap my mind around was finalization, but 
that is also due to the fact that I couldn't find understandable (read: 
understandable to me) documentation about the underlying concept in 
Pharo.


(OT: Finalization and concurrency probably is more about the concept 
rather than the implementation in Pharo?)


This is a piece of opinion. We all know, that unfortunately, one doesn't 
have to have knowledge to have an opinion, so if my opinion is wrong due 
to lack of knowledge, please ignore it.

I might be a bit fundamentalistic, but shouldn't this (a using class
