Re: [Pharo-users] image/vm mismatch on raspberry pi model 3

[Greg Lewin]

(I want to try https://github.com/pharo-iot/PharoThings on the pi) - I
now see there is another VM on there ... I have just tried it with
better results.  Matching image-VM versions does seem to be a problem
with Smalltalk.

[Pharo-users] image/vm mismatch on raspberry pi model 3

[Greg Lewin]

Hi,


Having copied a viable pair of image+changes and its associated
sources file to a pi 3,  in the same directory as the directory from
the zip file (from
https://ci.inria.fr/pharo/view/RaspberryPi/job/RaspberryPi-Publish/ws/64.zip)
containing the VM code for a rpi,

on running

./PharoS Pharo6.1

I get the message

"This interpreter (vers. 6505) cannot read image file (vers. 6521)."

How does one ensure a match between VM and image+sources on raspberry pi ?

I have also tried one image pair from an earlier version and get a
similar message.

thanks

Greg

Re: [Pharo-users] in-image pharo user objet ?

[Offray Vladimir Luna Cárdenas]

Hi,

I wonder why first and last name are not good enough. I have found the
model clear and privacy aware. Such image id is complemented with remote
credentials in remote repositories (SmalltalkHub, GitHub, etc) and I
deploy distinct images for distinct projects or releases (which is now
easier with PharoLauncher), so I fail to see other use cases.

Cheers,

Offray

[Pharo-users] Is there a way to set form colours using a 'fuzzy' option?

[Andy Burnett]

I have an image with black text, and a white background. I would like to
set the white pixels to transparent. I worked out how to do this, but of
course it leaves me with a white halo around the text, where the border
pixels are almost white, but not quite.

In googling about this, I discovered that RMagick has the idea of replacing
pixels which are almost any particular colour. I didn't find anything
similar in the ColorForm class. Is there a way to do this within Pharo?

Cheers
Andy

Cool! Can't wait to read :) One small question: why
"Booklet-Infrastructure"? That doesn't seem to match up to "A booklet on the

I run the newest Pharo 6.1 64bit (Installed via curl zeroconf URL

not think of a hint to your problem, right now.

Hi Juraj.

You can find new version here

still draft version but in general all parts are covered now.

[Pharo-users] Running headless on Windows

[Andrei Stebakov]

When I run Pharo 6.1 with -- headless option on Windows, it executes the
eval command as expected but during the execution (which lasts 4 sec) it
opens the Pharo GUI.
Is it expected? I thought headless means that the whole execution would
happen in the background

[Pharo-users] in-image pharo user objet ?

[Cédrick Béler]

Hi all,

For now, it is asked (by convention) a string containing our first name and 
last name (when code is submitted).
Just wandering if you could have a better representation of a user of a Pharo 
image.

Could we imagine a user id instead ? 
That shouldn’t be heavy to deal with and eventually one could add more 
functionalities (one being the authentification to a pharo based application).

The difficulty is to find a proper universal user id. I would have used 
something that encode date and place of birth in the id but it suffers some 
privacy related issues. Any ideas ?
Another question is if an image may be used by several people ? To me allowing 
one user is ok for a developer image but it might be interesting to switch user 
spaces if it’s for a pharo application ?

Cheers,

Cédrick

It is done in latest stable version. In addition there is new behavior when
user selects extended class (which is grey in class list):

- extending package group is added to the method group list. It is placed
just after "extensions" group.
- extending package group is selected by default which shows only extended
methods instead of all method
- automatic selection of extended class side:

- if instance side is extended then browser switches to instance side when
you select it

- if class side is extended then browser switches to class side when you
select it

- if both sides are extended there will be two classes in class list:
"AClass" and "AClass class"


It means that now when you select extended class the browser will show
"expected" extended methods. You do not need anymore to scroll protocol
list to find current package. And you do not need to guess where extension
is actually defined: in instance side or in class side.

By strange co-incidence, I've just experienced a similar problem, that I've
never seen before.
Slightly rearranging my previous example...
Object >> myTest
"Object new myTest"
self inform: 'test'.
self halt.

evaluating the comment pops up 'test' but doesn't open a debugger at the
"self halt".
It was working earlier today, but since then I had an episode which opened
a large number of debug windows.
I guess it could somehow be related.

Actually its worse, Spotter doesn't show any contents,
and "1 inspect" from Playground does nothing, although that does work from
the old Workspace.
All a bit strange.  I'll move to fresh Image.

I can upload this Image if someone cared to give it a once over.

Re: [Pharo-users] Breakpoints in Pharo

[Nicolai Hess]

Works for me too (on windows).
But sometimes, a change and accept of the current method, does not removes
the "Breakpoint"-Icon.
So, it looks like there is a breakpoint, but isn't anymore and the code of
course does not trigger the debugger.
The icon vanishes, if I unselect and select the current method.

Just tried it in Pharo 6.1 on Linux 32 bit. Breakpoints work. So presumably
this is a Pharo on Windows issue.
