can you resize the pharo windows ? I saw you struggle with it there

This is an iPad2. Pure Morphic is fine, what is not is Nautilus. I
guess with AltBrowser it would be fine.
I've had a game I wrote for kids (internal stuff done for my wife's
kids help practice) and it was fine with drag and drop and all.
Now for games on iOS I do use Monkey-X. But I'd love to have a Pharo
set of classes that would be gaming specific.
Me too.
I proposed a topic going in that direction for array based board game.
Now could you spend some time to describe what you would like and what
classes would be needed?
We could have very fast plugins for all the game engine and script it
with Pharo. Kind of what one does with Lua.
The touch paradigm is different from what one can do on a desktop. It
is not that Pharo has to work on an iPad. What would be nicer is to
have an image running on it and to which one would connect remotely
for remote coding.
Yes :)
What I was interested in with the bluetooth keyboard project is to see
how to have a kind of dynabook style thing. But Apple has crippled a
lot of things, like for an external keyboard support like this one has
to use internal undocumented APIs for the gsEvents and this will
prevent anything to go to the AppStore. And then one sees apps like
iAWriter which has such keyboard support, that's weird.
It depends who is the application validator. My impression is that their
process sucks.
I talked once with john and it was a bit surnatural.
Also, as a result, you realize that there is no ESC key on an iPad,
that you miss a ton of keys that you take for granted on a desktop.
Also, all keyboard scancodes are different in various brands and it is
a true ball of knots. No wonder Apple has one supersimplified protocol
for input that prevents your from doing powerful keyboard based
things. Meh.
Long story short, Android looks much better in that regard, and that's
where I am looking at these days.
I've got a new Galaxy Alpha Octocore thing and frankly, it blows any
iPhone 6 out of the water. I am done with iOS I'd say.
When going to places, there are so much more Android devices than
iDevices... These Android things are like the beige boxes of the 90's.
You know who won at the time.
So, next holidays, I'll have a look at CogDroid from JB.
Cool. JB will be happy and I hope he will push the rewrite of the event
model further.
When one can buy a full quad core stick PC with 2G of RAM and 8G of
storage for less than $50, well, choice is clear.
An old example:

That's where I want Pharo to run.

Now that my image is working properly again and the fires
have been put out,
I wanted to introduce myself a bit better...
My name is David Boeren. I first learned Smalltalk back
in college many
years ago, we used Smalltalk V in an object oriented
programming class I
took which was first-half Smalltalk, second-half C++.
This would be about
1992 I think? In recent years I've mainly been using
Java, with occasional
Python dabblings. I remember installing Squeak once or
twice over the
years, but to be honest it felt a bit clunky, perhaps this
was just an early
primitive version or whatever.
Recently, I've been getting the itch to try out some
different languages. I
was kind of looking at Scala or Clojure, one co-worker
suggested Erlang, and
so forth. But after doing a brief review I ended up
coming back to
Smalltalk which even after all these years still stands
right up with the
cutting edge I think. Sure, there are a few things that I
think would be a
little different if it were designed today like tuple
support or whatever,
but it feels like the right choice for something I'm going
to use mainly for
"fun" projects and the interactive environment is awesome.
One thing I wanted to ask about is the status of getting
Pharo running on
iOS (or at least iPad). I found some old posts but
nothing much within the
last couple of years. I know there were app store policy
issues in the past
but I think that Apple has opened things up a bit since
then, you can now
get Pythonista in the app store, or Codea. Is there still
an obstacle or is
it just something that hasn't been gotten around to yet?
I'd love to get it
running on my iPad Mini and be able to transmit code back
and forth between
there and my laptop to work on it wherever I'm at.
Second, I'm running into an oddity and I'm not sure what
I'm doing wrong or
whether this is a bug of some sort, this has to do with
trying to replace
unicode characters in a string which seems like it should be a
straightforward operation. Here is my code:
"Fetch the raw JSON data from dtdb.co
<http://dtdb.co>"
response := 'http://dtdb.co/api/cards/' asUrl
retrieveContents asString.
"Clean up the data a bit to make it a little more
regular"
response := response copyReplaceAll: 'null' with:
'""'.
response := response copyReplaceAll: '\u2022'
with: ','.
response := response copyReplaceAll: '\u009e'
with: 'e'.
Basically I'm just pulling some JSON data and then doing a
few string
replacements to make the data suit my needs. The first
one works. The
second one works. Since the third one ALSO uses a \uXXXX
code I would
expect it to work too, but it does not - the accented
characters are still
there.
To get a bit more visibility into this, I copied the
CopyReplaceAll code
from SequenceableCollection into a scratch class method
and adding some
Transcript output:
copyReplaceIn: aString All: oldSubCollection with:
newCollection
"Answer a copy of the receiver in which all
occurrences of
oldSubCollection have been replaced by newCollection "
| startSearch currentIndex endIndex |
Transcript show: 'start' ; cr.
startSearch := 1.
[(currentIndex := aString indexOfSubCollection:
oldSubCollection
startingAt: startSearch) > 0]
whileTrue: [
Transcript show: 'Found at index '
; show: currentIndex ; cr.
endIndex := currentIndex +
oldSubCollection size - 1.
aString := aString
copyReplaceFrom: currentIndex
to: endIndex
with: newCollection.
startSearch :=
currentIndex + newCollection size].
Transcript show: 'done' ; cr.
^ aString
A minimal test seemed to work:
HelloWorld copyReplaceIn: 'R\u00e9my Lapointe' All:
'\u00e9' with: 'e'.
start
Found at index 2
done
Testing this with the real data worked too:
HelloWorld copyReplaceIn: ('http://dtdb.co/api/cards/' asUrl
retrieveContents asString) All: '\u00e9' with: 'e'.
start
Found at index 22379
Found at index 22500
done
However, when I went back to using the regular
copyReplaceAll:With: method
it does not work and I'm not sure why. When it executes this:
aString indexOfSubCollection: oldSubCollection startingAt:
startSearch
The value comes back as 0 even though it's the same data from
'http://dtdb.co/api/cards/' asUrl retrieveContents
asString (I added a "self
halt" to be able to step into the method and view the
variable values), and
I'm not sure what the difference is. There shouldn't be a
limit on the size
of the collection, should there? The whole thing is
around 116k which is
big but not ridiculously so. It is however big enough
that the debugger
can't show the whole value, or at least I haven't found a
way to do so.
And last, is there a good video tutorial for the Pharo
beginner on how to
use the various browsers, debugger, tools, etc... that
come with Pharo? I
would like to start learning more about the best ways to
use these in my
development processes. I'm also having a lot of trouble
finding the correct
classes and message for what I want to do, searching
online w/ Google often
seem to turn up outdated information (or for a different
smalltalk flavor)
and it can take a while to figure out the correct way to
do things. Is
there a good central reference for the APIs somewhere? I
know that you can
search in the browser but I usually don't know the name to
search for. It
would be good to have a handy reference detailing how to
do all the
commonplace stuff.
Thanks!
