That's great, even faster than bioPython, and thanks to Petit Parser. That's great! I hope it will be on good place on Pharo's web site...

Ok, I solved the problem of the Unicode plugin: I removed it :) for the old vm, I don't know what is the impact, but it seems to work. Phratch can be loaded on Android now, but it is really slow, i am checking that.

Hi, I am trying with Pharo2.0. It seems to work but I have 2 errors: - the vm seems old: I have a message that says the vm should be updated - Unicode plugin seems not available. I have to change something in my code to not use it ?

Re: [Pharo-users] Voyage: Circular references

by Sabine KnÃ¶fel

Hi Esteban, thanks! I think the solution of Bernat will not be enough for me. I added the class methods isVoyageRoot to the root objects (like trip, country and so on). But I have instances which should never be persistent, e.g. the country I mentioned. The Country has currencies and expense rates and this is a lot of stuff...this should be only transient in the image. The transient country is referenced by persistent instances of trip. (countrie does naturally not point to trips) Trip (persistant) -> Country (transient) If I try to save a trip, voyage at some point enters >>rawReference: description: and there, it looks whether anObject (a country) isNew: isNew means the other object, the country has an _id (mongo id). The country does not have an id and for this reason, voyage tries to make it persistent although its class has isVogageRoot false. And than the system enters a point where it tries to make so many objects persistent that the image does not respond anymore. So, my question is: is it possible to define "In class trip, there is an inst var country -> voyage please save only a symbol here" and "voyage, if loading a trip, for inst var country, do shting" Sure, I could save symbols within the trips country inst var all the time and get the country it if needed, but it would be nicer if voyage coud do that for me .-) Sabine On Fri, Jul 19, 2013 at 11:52 AM, EstebanLM [via Smalltalk] <ml-node+s1294792n4699516h91(a)n4.nabble.com> wrote: > Hi Sabine, > > If Bernat help is not enough, I would like to have some more insight on your > problem, so If you can put here a better description of your model and the > problem you are having, I will have a look :) > > Esteban > > On Jul 19, 2013, at 10:42 AM, Bernat Romagosa <[hidden email]> wrote: > > Hi Sabine! > > If you want an object to be referenced by another, and not embedded in it, > you need to give that object root entity.

Hi Bernat, I'm going on vacations tomorrow, but if you provide me a way to test the plugin (like for example doing a remote session ;) ), I promise to work on fix it as soon as I'm back (I'm going out just one week). can you locate some time for doing it?

Re: [Pharo-users] SerialPlugin

by Bernat Romagosa

Hi Ricardo, By using exactly your same packages, it still didn't work on Linux. So I guess I'm stuck with a proprietary system for the moment... :( It seems to work on Mac, no compiling or tweaking needed, so I'll start working on a Mac box for the moment, although I'm as productive on anything but my PC as if coding with a typewriter... I'll still keep looking at the Unix plugin code to see if I can fix it. I think I've spotted something weird at: if ((sp->spDescriptor= open(portName, O_RDWR | O_NONBLOCK | O_NOCTTY)) < 0) { fprintf(stderr, "Error while opening the serial port (%s).\n", portName); return portOpenFailed(sp); } This fprintf prints: Error while opening the serial port (/dev/ttyUSB0!). Notice the last character inside the parens. Sometimes it's a $!, sometimes it's a $9. This smells like we're reading one position more than needed from the char array, but I've tried changing its size and, even when portName has the right value, open() still returns -1... 2013/7/18 Ricardo Moran <richi.moran(a)gmail.com> > Hi, I just tried Pharo2.0 Latest update: #20596 with the following VM (on > Windows): > > NBCoInterpreter NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: > a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 > NBCogit NativeBoost-CogPlugin-EstebanLorenzano.18 uuid: > a53445f9-c0c0-4015-97a3-be7db8d9ed6b Mar 13 2013 > git://gitorious.org/cogvm/blessed.git Commit: > 412abef33cbed05cf1d75329e451d71c0c6aa5a7 Date: 2013-03-13 17:48:50 +0100 > By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #14535 > > The serial port seems to work fine here.

Re: [Pharo-users] Voyage: Circular references

by Bernat Romagosa

Hi Sabine! If you want an object to be referenced by another, and not embedded in it, you need to give that object root entity. As a root, the object will have a collection of its own, and will be referenced by other objects by id. If the object is not root, it will be embedded inside the referring object as a property. So, to be safe, always set #isVoyageRoot to return true at class side of all objects you don't want to have embedded. In general, "big enough" objects who are referenced by different objects should be root. In my case, I had a centre which had users which had centres. Users also had projects, and projects also had users. Big mess, I know. Besides that, all users, centres and projects had profiles. My solution was to make centres, projects and users be roots, and let only the profiles be embedded. I hope this helped!
