Thanks Doru,
I commented on the bug report.
Will this be included in the (left most) inspector pane in the debugger?
(this is difficult to use in the "State"-pane, because as soon as you try to
bring up the popup-menu, the pane "slides away").

Re: [Pharo-users] Memory mapped files and Pharo (aka Unreal Engine 4 integration with Pharo)

[Dimitris Chloupis]

Pipes are actually slower than sockets (local UNIX sockets that is) and I
dont need sockets if I am using shared memory.

I could create an event que and not allow direct access to shared memory,
this way I make sure everything happens in order and in sequence. This way
I can make sure multiple writes and reads dont happen at the same time.
This could be a first implementation and if the need arises for multi
threading then I can revise this design but frankly I rather stay away from
multithreading and other complexities and keep this simple and easy to
learn and code.

I don't know if there is an easy solution. But it was nice in the old

Re: [Pharo-users] Creation form from PNG file very slow on Pharo 4 and 5

[Dimitris Chloupis]

Fuel is great indeed and very convenient ,will definetly use this approach
if I end up dealing with a lot of PNGs and experience some serious delays,
but for now, lazy loading with some forking should be enough to make this
instantaneous .  I prefer to stick with pngs because it easy to update them
and version control them via git and github

Re: [Pharo-users] Memory mapped files and Pharo (aka Unreal Engine 4 integration with Pharo)

First a disclaimer, I do not have a lot of experience with inter-process

Communication through mmaped files, or shared memory in general, is inherently 
asynchronous, so lack of multiple OS threads should not be a blocker if the 
protocol is well designed.

I expect you would need some sort of out-of-band signalling so polling is not 
necessary. Pipes or sockets could be used for that, slower for data transfer 
(more copying), but they are compatible with select() and other OS polling 
features.

You could build synchronisation primitives on top of sockets, too. But building 
things like mutexes would be inefficient. I guess you could use pipes for all 
the  message sending and memory management, and shared memory for bulk data 
transfer. Large number of messages could be handled in batch this way:

allocate a message area (socket round trip)
fill the message area
signal to process a block of messages (socket one way)
optimistically check for incoming messages in shared memory
wait for socket input

Not very efficient for messages that depend on one another. But I am not sure 
you could do better without things like interprocess semaphores or a FFI.

We have now moved the accept and cancel to the contextual menu for now. 
However, the longer term goal is to change this pattern. Here is a longer 
explanation.

We think of the IDE like terms an object-oriented system built using a 
language. From this point of view, an action is put in the context that 
provides enough information to trigger it. So, for actions that do not rely on 
the selection, or on the cursor position, we can safely put them in the toolbar 
of the presentation. For global actions (like refreshing the whole inspector), 
we put them all the way in the title bar.

For example:
- "Do It” depends on the selection or cursor, and thus it is added to the 
context menu
- “Accept" is not specific to the current location of the cursor or of the 
selection and can be made presentation specific (added to the toolbar of the 
presentation).
- Switching the whole debugger to a “Bytecode” one is global for the whole 
debugger, and it is added to the top of the visual hierarchy.

This choice also documents the scope of an action. For example, imagine having 
a global toolbar with actions that only do something in a certain pane (out of 
possible many). How will you know before triggering what is the effect going to 
be? But, if you always put the action to the scope that it affects, there is a 
more clear connection because cause and effect.

And there is yet another advantage. When you stick with this design, you get 
potentially reusable components.

This does require some getting used to. And this design will not necessarily 
work for general UIs. But, an IDE is not a general UI. It is made for 
programmers, and in our case, it is made for object-oriented programmers, and 
we can use the abilities of such programmers in our designs.

Does this explanation make more sense?

Cheers,
Doru

If you want to help for real this is the time.

https://ci.inria.fr/pharo-contribution/view/Books/job/UpdatedPharoByExample/lastSuccessfulBuild/artifact/book-result/UpdatedPharoByExample.pdf

I rewrote the chapter on metaclass and a couple of other points because 
TranslucentColor is not available anymore.
I will not rewrite what I do not like (I should now have written in the

for the perfect solution but to get something done.

- First
we will host http://www.pharoByExample.org at http://books.pharo.org

- Second
we will create a new entry for Updated pharo by example and (a new

- Third

Yeah, I'm never sure whether it's the remote site or my ISP. Can't wait until 
my contract is up. They won't let me use bit torrent and they arbitrarily don't 
allow certain downloads through. I end up at the library in order to download 
some things like unix distros.

[Pharo-users] Fogbuz issues

[Dimitris Chloupis]

Since I am on a complaining spree lately let me complain once more.

I really dont like Fogbuz and in order not to bore with blah blah lets get
to 2 big issues

1) If you open a bug report it does not subscribe you to it, WTF !!! Who
else could be more interested in my bug report than I ?

2) If I go to My Cases its shows none of the reports I opened , actually it
shows nothing, none, zero , empty space  WTF^2

And people then wonder why on earth I keep pushing for github integration,
thats why !

Re: [Pharo-users] (no subject)

[Dimitris Chloupis]

I think its the server,  I have internet connections issues too, my adsl is
down because of a faulty cable that the adsl provide not my ISP refused so
far to replace, I use my mobile internet connection that is rock solid
(ironic that mobile phone offers better internet connection than adsl) so I
am pretty sure it was the pharo server.

In the top right corner of Fogbugz there is a menu which has an entry called 
“subscriptions” here you can configure what you want to be automatically

Re: [Pharo-users] Spec: Populating a playground with a particular content (was Re: Spec: Binding widgets how to)

[Tudor Girba]

Hi,

For your tabulator example, you can do something like:

browser := GLMTabulator new.
browser title: 'Código'.
browser column: #code.
browser transmit 
to: #code;
  transformed: [ :text | GTPlayPage new content: text ];
andShow: [ :a :page | a custom: (GTPlayground new startOn: page) ].
^ browser openOn: 'a := 42’.

Does this help?

Doru

Re: [Pharo-users] Getting Updated Pharo By Example out the door

[Dimitris Chloupis]

I am here to help you Stef , I am actually doing what you are doing going
one chapter at a time, but for me its not 3 chapter per week but rather 1
chapter per week but I can boost my speed to 3 chapters per week and just
dont pay so much attention to detail as I currently do. My goal so far was
to focus on Pharo 4 and not Pharo 5, so I can make a Pharo 4 release
(github release and github tag) and then move to pharo 5 at least one month
before pharo 5 is released.

But because I know that your MOOC is based on Pharo 5 maybe you want to
move UPBE directly to pharo 5 (not hard to do because we have already
documented some parts of pharo 5) which works for me too.

Re: [Pharo-users] Fogbuz issues

[Dimitris Chloupis]

You can indeed interpret My Cases as "assigned to me" but my first thought
was when I saw "My Cases" is to assume that is the cases i opened.

In any case I created my own custom filter with openedBy:me and saved it as
"My Opened Cases" and I also used the Henrik suggestion to subscribe to all
relevant opened and closed case I am interested for. So hopefully this is
the end of my frustration though I am sure I will find something to
complain about :D

So yes fogbuz is not that bad once you figure out how it works, but is
confusing for newcomers to say the least.

This impedance mismatch is because its a professional tool designed
for commercial in-house bug tracking, where users have no access to
it.  So the "my" is "my cases" is always a developer working on
someone else's bug.   In our case there is little distinction between
our users and our developers.  For this reason, Fogbugz doesn't always
exactly match our needs, but I think it is sufficient, and we are
lucky to have the free access to it that we have. It would be a big
job moving, which we should delay as long as reasonably possible.

Re: [Pharo-users] Pharo 5 new vm crash on window resize

[Pharo-users] Memory mapped files and Pharo (aka Unreal Engine 4 integration with Pharo)

[Dimitris Chloupis]

An apology for the long post but this is not a simple issue and hence not a
simple question.

So I am looking into ways to integrate Pharo with Unreal to bring some
nuclear powered graphics to Pharo and make us first class citizents to 2D
and 3D world.

For those not aware this is unreal

https://www.unrealengine.com/what-is-unreal-engine-4

As suprising it may sound Unreal and Pharo share a lot in common

1) Both integrated languages with IDEs
2) Both promote live coding and live manipulation of data
3) Both promote visual coding
4) Both promote ease of use and wizard based development (aka RAD)

Unreal is indeed a C++ based project made to be used by C++ coders but it
comes with a very powerful visual coding language that can map visual nodes
to any C++ function/Method and another common ground with Pharo is the very
strict OO nature of both projects. But then OOP is very big in game
development anyway.

Of course my goal is not to force Pharoers to learn C++, but rather make a
Pharo API so Pharo can be used to do some simple graphics development in
the start and then we can continue importing more and more functionality.
Unreal is generally a heavy engine that requires quite a powerful GPU but
its rendering is just amazing.

So how I make Pharo talk to Unreal is the million dollar question.

The road of compiling Unreal as a set of DLLs to be loaded by Pharo via FFI
is a road full of thorns because its quite an undertaking cause Unreal is
HUGE and it will be nightmare to maintain since Unreal moves forward very
fast.

So we come to the subject of IPC, or Inter Process Communication. I am not
new to this as you know I have build a socket bridge between Pharo and
Python that allows Pharo to use Python libraries and in my implementation I
focus on Blender Python API.

But sockets are not exactly blazzing fast, calling functions is fine
because you can even get responses bellow 1 millisecond but if try to run
some heavy loops you will be in trouble. There are work arounds of course,
like sending the loop with the socket and language etc but they
overcomplicate something that at least in my opinion should remain simple.

Another IPC method is shared memory, it is what it says , basically
processes that share a place in memory where they can access the same data.
Extremely fast but it has its own traps for example how to make sure the
processes dont access the same data at the same time etc.

So after some reading I came across to a shared memory model called Memory
mapped files, basically what that means is essentially a virtual file that
resides on memory (it may also reside on the hard disk or other permanent
physical storage but its not necessary) that different processes can
access.

So in our case we can have memory mapped file that Unreal , Pharo and even
Blender can access where we can store command / messages that each
diffirent application must execute, let them share data and sky is the
limit.

Now I know this will not be a walk in the park specially to someone like me
a C++ noob but I am looking for the Pharo wisemen wisewomen to guide me at
least through the obstacles of this.

So the questions are the following

1) Do you think this is possible with the current Pharo ?

2) Will I be limited by the fact that the VM currently does not multithread
or cannot use multithreading libraries ? ( I have no intention of using
multithreading but some handling of process access to the data may be
necessary to make sure data is safe from concurent modification)

3) Is there anything else I should be aware of as common pitfalls for such
implementation ?

4) Can the current FFI help in this task or would I need to implement this
as a C DLL and load it from Pharo

PS: I have no intention of messing with the Pharo VM and I also want to
avoid the use of plugins as I want this to work with standard Pharo
distributions.

Re: [Pharo-users] Fogbuz issues

[Dimitris Chloupis]

ah ok did not know that is a common practice for pro devs , well if fogbuz
is a pro approved tool and it works very well I am perfectly ok with using
it and documenting it for newcomers.

nah that ok I am joking of course

"Ok this is good to know for 50.

No I did not, and I will but please note that the exact same code works
fine on Pharo 5. But most likely I will migrate back to 5 at some point and
will end up closing this bug report so its not a big deal for me. I dont
like leaving bug reports open ;)
