Pharo how to get carect symbol

by Rafael Luque

Hi all, I don't know how to get the caret (^) symbol inside Pharo in my Linux laptop. The usual combination of keys that work for me in other applications like browser, emacs or terminal does not work inside Pharo. This is the VM version output: M: NBCoInterpreter NativeBoost-CogPlugin-GuillermoPolito.19 uuid: acc98e51-2fba-4841-a965-2975997bba66 May 15 2014 NBCogit NativeBoost-CogPlugin-GuillermoPolito.19 uuid: acc98e51-2fba-4841-a965-2975997bba66 May 15 2014 https://github.com/pharo-project/pharo-vm.git Commit: ed4a4f59208968a21d82fd2406f75c2c4de558b2 Date: 2014-05-15 18:23:04 +0200 By: Esteban Lorenzano <estebanlm(a)gmail.com> Jenkins build #14826 I'm trying with the following images: * 4.0 #40360 * 3.0 #30860 Thank you.

Re: [Pharo-users] Ploting all history of the commits in a Monticello repository

by Pierre CHANSON

Hi Offray ! from Pharo you can access the monticello repository with the following code: myRepository := MCSmalltalkhubRepository location: <anUrl>. then you can get: myRepository allVersionNames. Finally you can get the commits informations (message, author, date etc.) using: myRepository versionInfoFromVersionNamed: <aVersionName>. For exemple supposing you want to list all the commit date and time logs from your repository, result contained in a dictionary with the version names as keys you can execute: -=-=-=-=-=-=-=-=-=-=-=-= result:= Dictionary new. repo := (MCSmalltalkhubRepository location: ' http://smalltalkhub.com/mc/Offray/Ubakye/main'). (repo allVersionNames sortedAs: [ :e | e extractNumber ]) asArray do: [ :v | vers := repo versionInfoFromVersionNamed:v. result add: ( v -> (Array with: (vers date) with: (vers time)))]. -=-=-=-=-=-=-=-=-=-=-=-= Cheers, Pierre 2014-11-10 14:53 GMT-03:00 Offray Vladimir Luna CÃ¡rdenas <offray(a)riseup.net> : > Hi, > > I don't know if the terminology is the proper one.

Glamour stream presentations

by Evan Donahue

Hello, I was just wondering if it was possible to use list/table presentations (or an analogous presentation) in Glamour to display streams that load on demand as you page through them (rather than loading all entries into memory before displaying the first page). If not, does anyone have any tips on the best way to go about creating one? Thanks, Evan

Nice to know. I'll give it a shot on my Ubuntu 14.04 in the evening. As I may have more than one image connecting to the R, I will still need something with RServe at one point I guess.

Re: [Pharo-users] Anyone having a Rserve client?

by Blondeau Vincent

Hi, Last two weeks, I began to write a binding with nativeboost to call the R functions. It is a proof of concept for now : http://www.smalltalkhub.com/#!/~VincentBlondeau/RProjectConnector if you want to participate, just ask me! You have to download the right libraries to do it work. It is the .dll in the same folder of the R.exe executable. I think that it is the same for Linux and MacOS. And copy them it in the same folder that the pharo executable. I think that nativeboost binding will be faster than RServer and more easy to use that why I started this.

Good ;-) > Is there more docs about the caching somewhere? I read the code, comments, and unit tests but still, will value an explanation. I tried to comment everything, the class comments (check AbstractCache too) are quite extensive. What else do you want to know ? > Keying by object works, but with symbols, it isn't behaving. I think I miss something here. I don't understand, AFAIK you can use any object as both key and value, most tests use Symbols. Can you elaborate ? > Is the cache size set at a given limit? I think you are looking for CacheWeight (read the class comment). Basically, a cache has a weight, if it is exceeded, it starts removing items. How you compute the weight is up to you, the default is that each entry has a weight of 1, so you end up counting the entries. But you could use something like file or byte size of the value. > I see keyIndex is Dictionary new. What if I do have a lot of keys? Is the dictionary being copied over and over to get to the right size? Yes, of course it is a dictionary that grows when needed, what else do you want ? You want to predefine it at a certain size ? Sven PS: BTW, the implementation is slightly more complicated than what you would expect, it uses a double linked list and an index dictionary, to achieve proper O(1) performance in its common operations (accessing, adding & evicting entries). > Phil > > > Phil > > Phil > > > > > > > On Tue, Nov 11, 2014 at 7:52 PM, phil(a)highoctane.be <phil(a)highoctane.be> wrote: > I should ask more questions :-). > > Now, this still doesn't answer the question on how to use this to memoize object methods. > > I think that what is closest to what I am looking for is this: > > http://wiki.tcl.tk/10779 > http://wiki.tcl.tk/10981 > > > I am use we can do something like that in Pharo, with some memoize method in Object playing around with thisContext. > > SomeClass>>someMethodWith: aSomething and: aSomethingElse > > > > Like self haltIf: aSymbol will break if aSymbol is in the call stack. > > Any guru having a way to do that? > > Phil > > > > > On Tue, Nov 11, 2014 at 7:21 PM, Torsten Bergmann <astares(a)gmx.de> wrote: > Werner Kassens wrote: > >Hi, > >now this a nice idea, especially the memoizedUsing:cache idea. i would > >really appreciate it, if that would be MIT licenced. > >werner > > It already is, thanks to the permission of author John Cromartie who answered > us today.
