It handles shared, circular references, and thus graphs. It short circuits classes by using their global name.

Reliable way to persist graph of object

by Hilaire

Hi, I already reported here the main problem of Fuel, no upward compatibility among Pharo version. It is a bit pathetic as it nullified a lot the interest of Fuel. Fuel in itself is really great, so it makes this situation even sadder. Phratch is another victim of this problem. Phratch users can't load their projects on newer version of Phratch (newer as based on newer version of Pharo). An option could be to stick Phratch releases to one specific version of Pharo. But not ideal. So all in all what are the options we have to persist reliably and with compatibility a graph of objects. Thanks Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] Phobos and printing

by Pavel Krivanek

Hi Hilaire, I will look at it. Are you interested to have Phobos for Pharo 6? The main problem of Phobos is the stopped support of XULRunner by Mozilla without substitute so it's not good idea to use it for long-term projects.

Re: [Pharo-users] Pharo not opening my image automatically

by Dimitris Chloupis

It does but I do not want to do that, I prefer the traditional way to click on my dock and that Pharo opens my image because I use only one image. I store my libraries using git and github. I do not even save the image unless I really have to store the live state and that rarely happens. On the other hand I do rebuilt my image daily , I have added a setup on catalog browser( which downloads and installs a bunch of libraries I depend on ) and a startup configuration file ( it launches the setups the first time an image is opened ) and a make file which does all this automatically when I issue "make run" on command line. My next step is to replace the makefile with a Pharo GUI because I want to completely abandon the command line which I do not like using.

I don't know, on MacOS I always have dragged the image I want to open to the pharo app. That works for me.

and you are awesome, yeap macos has plist file inside the Pharo.app , equivalent to windows ini.

Re: [Pharo-users] Pharo not opening my image automatically

by phil＠highoctane.be

In Windows, you set the image name in the ini file to have it opened automagically. Now, maybe there is a plist file on macOS that supports the same.

Phobos and printing

by Hilaire

Hi Pavel, Is there a way to ask a PhobosHTMLCanvas instance to print an html file. I have html files built from Mustache templates and I try to send it to the print dialog via Phobos. So far I send an entire locale html file content via #rawXML: message, but I got mix results, the style does not seem to be taken in consideration. Thanks Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] self in Nautilus

by Stephane Ducasse

Yes. This trick is handy but totally confusing. I think that self in playground should return nil. because self only makes sense in method body and inspector pane.
