[Pharo-users] SixxExamples class >> example 4 . Preferences in Pharo 4.0

[H. Hirzel]

Hello

How would I write the following SIXX example in Pharo 4.0?

example4
"SixxExamples example4"
"Save and load Preferences data"

| preferences |
preferences := Preferences allPreferenceObjects sixxString.
preferences := Object readSixxFrom: preferences.
^preferences inspect.


Preferences is marked red.

[Pharo-users] Becoming good at VM development

[Ichiseki]

Hi
hello to everyone & everybody
I am interesting in going deeply into VM design, development, optimization,
etc. I know a lot of Haskell, a good amount of C and some languages that use
VM like Python, Lua and Pharo of course.
What would be a road map (books, articles, code to read) to understand
deeply and in detail the Pharo VM, the inter operation between the VM and
the image. I know this could take a lot of time but I'm committed to invest
that time.
Please help me as literature on these topics is very scarce...
Thank SO SO much in advacne

P.S. And BTW besides SIXX what options do I have to transfer
preferences from one Pharo 4.0 image to another?

Get a copy of Smalltalk blue book and read implementation part. It is very
old, but it would get you many important ideas.

http://stephane.ducasse.free.fr/FreeBooks/BlueBook/Bluebook.pdf

after that, there is a source of Squek/Pharo virtual machines, and you can
even run and debug them it inside Pharo.

Preferences does not exist as a class.

You could use STON.

Yes, we need re-thing and improve Preference modelling and storage.

I very strongly agree... Anything which prevents failure on non-present
class, or settings selector change, gets my vote.

Sorry, I was on holidays… Yes, TWM supports multi-desktops, but it's been
buggy since Pharo 4.0 and I've never tried on 5.0.

Re: [Pharo-users] Becoming good at VM development

[Ichiseki]

I've already read those blogs. There are lots of useful information - it
seems - but what I want is a head start, something that starts from zero but
for someone who has programming knowledge.
I will definitely read the blue book. That goes first!
Any more sources, indications?

[stepharo]

STON is the way to go to save preferences.
But I do not have free cycles.

Re: [Pharo-users] Becoming good at VM development

[Christian Caldeiro]

Hi Ichiro,

there are a bunch of posts in Mariano Martinez Peck's blog named "journey
through the VM", done some years ago. He writes about anything related to
the VM, how to build it, class format, bytecodes, detailed description of
the CompiledMethod class, etc.

You can find the first post here:
https://marianopeck.wordpress.com/2011/03/31/journey-through-the-vm/

Definitely worth reading!

Cheers
Christian

[Pharo-users] Pharo 4.0 -- Inspecting a recursive data structure is slow

[H. Hirzel]

Hello

I have realized that inspecting a recursive data structure is very
slow in Pharo 4.0

A test case:

| myDict |
myDict := Dictionary new.
myDict at: #hello put: 'hello'.
myDict at: #recurHello put: myDict.
myDict inspect

It takes a long time for the inspector to come up. And the image
freezes later on if you continue.

The problem is with the inspector because if I do
| myDict |
myDict := Dictionary new.
myDict at: #hello put: 'hello'.
myDict at: #recurHello put: myDict.
3 + 4 inspect

it comes up instantly.


As a comparison I attach the Cuis ** test result. The inspector comes
up instantly and the image does not have any problems.


What are the workarounds in Pharo 4.0?

- Setting a time out somewhere?
- Disabling certain functions?
- Loading a simpler inspector?

Regards

Hannes
