Phratch on Ubuntu

by jannik laval

Dear Community, Thanks to Damien Cassou, Phratch can now be installed on Ubuntu using apt-get. If you are an Ubuntu user on 12.10, 13.10 or 14.04, you can very easily install Phratch. You have to add the Pharo PPA (ppa:pharo/stable) and install Phratch by issuing these commands: $ sudo add-apt-repository ppa:pharo/stable $ sudo apt-get update $ sudo apt-get install phratch Then just run $ phratch Thank you again Damien ! -- ~~Jannik Laval~~ Ãcole des Mines de Douai Enseignant-chercheur http://www.jannik-laval.eu http://car.mines-douai.fr/

XBRL parser/processor?

by Mariano Martinez Peck

Hi Smalltalkers, Sorry for the cross posting..... I wonder if anyway is aware of a Smalltalk parser/processor of XBRL (http://xbrl.sec.gov/) ? I know it's XML but it seems some extra work/features are needed besides a XML parser to fully support XBRL data extraction. Thanks in advance, -- Mariano http://marianopeck.wordpress.com

It was a decision of the language designers to forbid assignment to arguments to allow debugging. The assignment to block arguments is a side-effect of the old BlockContext implementation of blocks where block arguments were mapped onto temporary variables of the home context. It is an anachronism and should be forbidden also. > > Thank you for the explanation. > I'm just curious why it is so difficult to implement a debugger if arguments are assignable? > If you need to restart the execution of a method, and so you need to get the initial value of the argument, I understand you cannot find the value anymore in the method context but it is available in the caller context, no? > As I never implemented a debugger, I cannot figure out the difficulties. the args are no longer available; they get moved from the caller context to the callee. If you think about stack frames then what happens is that the slots containing the outgoing arguments are used as the slots for the incoming arguments. So if arguments are assigned to they are indeed lost. But look at how many methods in the system (or in any system). The proportion of methods/functions/procedures that could be written to assign their arguments is very small so the Smalltalk trade off is a good one. Eliot (phone)

What did you finally find out for speed up? > Hum, some crappy things. For example, to manage the z-index of the bubble talk: - a loop to draw all the morph - a second loop that select the buuble (isKindOf: bubble !!!) and draw only the bubble. These two loops are in the same method and called on each step... for a bubble that appears only 1 or 2 times in an application Removing the second loop makes Phratch 2x faster. I am continuing to clean that. I also find the problem with click-event. Now when I click, it works fine !

Please put energy into item #2, and postpone again until it's ready if necessary. :) Those who already use Pharo 3 know the risks of using a beta version, so they can wait until the release version is ready. :) Regards!
