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-$15k crowd-funding [4], but in the end it seems they bypassed that and Dec 2014 went straight to an MIT release [5]. I don't think we should take this as an opportunity to simply raid their coffers and ideally aim there would be some mutual beneficial to reward their move to open source. As I understand it, Dolphin is Microsoft only but using 32-bit Win32 API rather than .NET, although it can run under Wine[6], so Pharo has some advantages there - particularly considering the mobile arena. I doubt its practical to merge the two products since I *guess* much of Dolphin's attractiveness is its tight coupling to Microsoft, but since they've got this "ph" in their name, I can't help imagining a product with 64-bit Cog-Spur-Sista + lower level Pharo infrastructure + Dolphin GUI - that might be named "Dolpharo" ;) cheers -ben [1] http://forum.world.st/Terrible-News-Dolphin-is-Dying-td1408648.html [2] https://redmondmag.com/articles/2015/09/01/changing--dna.aspx [3] https://groups.google.com/forum/#!searchin/comp.lang.smalltalk.dolphin/open$...

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.

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

Standalone executables its not a big deal, you can rename the pharo executable to anything you want and heavily customise your image already with pharo. Standalone apps are a reality since before pharo was created , from squeak days.

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

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

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? --Hannes On 1/4/16, Pierce Ng <pierce@samadhiweb.com> wrote:

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.

Hi again, I tried on my Windows 7 64bits. 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.

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 :-) ) Regards, Esteban A. Maringolo
