Dolphin Smalltalk open-sourced...

...with MIT license, so I wonder if that will have some impact on
further development of Pharo?

Iirc, Dolphin can produce stand-alone Windows executable, but maybe
something else can be utilized as well?

Here is the link with: http://object-arts.com/gettingstarted.html

I dunno if they will be any impact on Pharo, because having a software
open-source is great, but you also need
a benevolent dictator and a community to give a direction ;-)

If the licence is MIT, this is great, because Pharo could reuse some
parts of Dolphin Smalltalk without any problems.

What about GUI builders for the desktop apps? Someone on #pharo
mentioned that Pharo is way behind Dolphin in this regard?

Really interesting news.  I was curious for some history and the
reason for the open sourcing, since back in 2007 Andy Bower said [1]
"It is with great regret and more than a touch of sadness that I have
to announce that Blair and I have made the decision to stop selling
and developing Dolphin Smalltalk. We will continue to distribute the
free version of Dolphin X6 indefinitely but, as from today, we will
not be selling the Professional version.  [...]  There will no doubt
be a number of you who would suggest that we Open Source Dolphin.  Of
course, you are free harbour such opinions and to  discuss the idea on
the newsgroup but please do not expect us to be persuaded.  It simply
will not happen! Both Blair and I dislike the Open Source movement
intensely and we would rather see Dolphin gradually disappear into the
sands of time than instantly lose all commercial value in one fell
swoop."

but then even Microsoft has significantly changed its stance on open source [2].

It seems there was initial discussion in Feb 2014 of pledges to open
source Dolphin [3], followed by ObjectArts proposal July 2014 for
$10-$15k crowd-funding [4], but in the end it seems they bypassed that
and Dec 2014 went straight to an MIT release [5].

I don't think we should take this as an opportunity to simply raid
their coffers and ideally aim there would be some mutual beneficial to
reward their move to open source.

As I understand it, Dolphin is Microsoft only but using 32-bit Win32
API rather than .NET, although it can run under Wine[6], so Pharo has
some advantages there - particularly considering the mobile arena.

I doubt its practical to merge the two products since I *guess* much
of Dolphin's attractiveness is its tight coupling to Microsoft, but
since they've got this "ph" in their name, I can't help imagining a
product with 64-bit Cog-Spur-Sista + lower level Pharo infrastructure
+ Dolphin GUI - that might be named "Dolpharo" ;)

Hi,

I am trying to run it, but I have troubles starting it.

I have a Windows 7 64 bit.

I did the following:
1. I downloaded the repo from:
https://github.com/objectarts/Dolphin
2. I then tried to run Dolphin7.exe and BootDCE.cmd, but in both cases I got the message:
“Missing msvcp120.dll”
3. I then installed this dll as described here:
http://dllwindows.com/download-msvcp120-dll/
4. I retried to Dolphin7.exe and BootDCE.cmd, but now I get
“The application was unable to start correctly (oxc000007b)”

Does anyone know what is wrong with what I am doing?

Cheers,
Doru

Did you followed the tutorial
http://www.object-arts.com/gettingstarted.html ?

    «Double-clck BootAll.cmd. A console window will open and
sequentially spawn the individual boot jobs. Depending on the heritage
of your Windows environment, you may see a failure message saying that
MSVCRT120.DLL cannot be found. If this is the case on your system, you
will need to download and install the Visual Studio 2013 Redistributable
components. Since Dolphin is a 32 bit application you’ll only need
vcredist_x86.exe. Once done, try the BootAll again.»

If you still have problems with it I can check on my window 7 64bits
when I will be at home.

I cloned the repo and ran BootAll.cmd and it ran right away in my
Windows 7 64 bit computer.

I cloned the Dolphin repo, launched BootAll.cmd then opened DPRO.img7
with Dolphin7.exe and everything worked out of the box.

I already had Visual C++ 2013 on my computer. Do you have it installed ?

Hi,

Indeed, something seems to have gone wrong with previous Visual C++ installation. I now reinstalled it and it worked.

Thanks for the help.

Cheers,

Look at the Aspect class and implementors of
#publishedAspectsOfInstances, that's very close to what the
GTInspector provides in a way I find easier to define (maybe because
my mind is shaped by it :-) )

The same.

I looked into moving source back and forth, and found an implementation of
Smalltalk Interchange File (SIF) by Eric Arseneau from the year 2000.  The
Squeak version files in on Pharo 4 (and Squeak 5) and files some code out
successfully (after a small change in symbol handling). Similarly the Dolphin
version files in but fails to import a Squeak file-out, because Dolphin doesn't
understand {} in Dictionary class>>newFromPairs:.  Next step is to look at the
compiler I suppose. Down the rabbit hole...

SIF is found here: http://www.pocketsmalltalk.com/sif/. Pocket Smalltalk,
now that's a very cool thing.

Thank you for the report, Pierce.

Did you use this
http://www.pocketsmalltalk.com/sif/contents/sifall.zip link (labeled
'sifall'.zip) to download the code?

Yes, that's the zip file I used.
