Re: [Pharo-project] refactoring

by Benjamin

It's a will known bug from RPackage which have some issues when importing categorize :S This should be fixed soon. (for retrieving your class, do a Find, then if you right click on the empty class list, you can access the menu, and move the selected invisible class in the package you want) Ben On Apr 19, 2012, at 11:51 PM, blake wrote: > On Thu, Apr 19, 2012 at 1:41 PM, Guillermo Polito > <guillermopolito(a)gmail.com> wrote: >> You have to install a browser with refactoring support, such as Nautilus. >> Open the configuration browser and load it from there :). > > I found this on Mariano's web site: > > Gofer it > url: 'http://ss3.gemstone.com/ss/Nautilus'; > package: 'ConfigurationOfNautilus'; > load. > > (Smalltalk at: #ConfigurationOfNautilus) perform: #loadRelease > > And that made the default browser the Nautilus browser.

I found this on Mariano's web site: Gofer it url: 'http://ss3.gemstone.com/ss/Nautilus'; package: 'ConfigurationOfNautilus'; load.

Re: [Pharo-project] PetitSmalltalk: now with a self-contained grammar for number literals

by Frank Shearar

I found a serious bug in parsing numbers with negative exponents. It was completey broken, in fact, parsing 1e-1 as 10, not 1 / 10. Anyway. This version fixes that, and adds a bunch of tests demonstrating that number parsing will return rationals if it can. It's significantly slower than Squeak's SqNumberParser: Time millisecondsToRun: [100000 timesRepeat: [SqNumberParser parse: '1234567890']] => 466 Time millisecondsToRun: [100000 timesRepeat: [PPSmalltalkNumberParser parse: '1234567890']] => 32082 I've attached a MessageTally spying on the latter: I've not much skill in reading these, but nothing leaps out at me as being obviously awful. frank On 14 September 2011 20:26, Frank Shearar <frank.shearar(a)gmail.com> wrote: > On 3 September 2011 19:35, Nicolas Cellier > <nicolas.cellier.aka.nice(a)gmail.com> wrote: >> 2011/9/3 Frank Shearar <frank.shearar(a)gmail.com>: >>> On 3 September 2011 18:50, Lukas Renggli <renggli(a)gmail.com> wrote: >>>> I think it is a good idea to have the number parser separate, after >>>> all it might also make sense to use it separately. >>>> >>>> It seems that the new Smalltalk grammar is significantly slower.

It seems that if there is a selector close enough the pop p shows ... So maybe it's expected :) Ben On Apr 19, 2012, at 11:05 PM, Mariano Martinez Peck wrote: > Hi guys.

[Pharo-project] Compiler does not barks anymore for unknown selectors?

by Mariano Martinez Peck

Hi guys. Previously, in Pharo 1.3, when compiling a method that has message sent to an unknown selector, the compiler used to bark and open a popup suggesting other similar messages or to choose the one you originally wanted. Now it does not bark nor opens a popup. Instead it direcly puts what I said. Is that expected? Thanks, -- Mariano http://marianopeck.wordpress.com

Re: [Pharo-project] The video about Athens

by Tudor Girba

Looks great. I just tried to give it a try, but I get stuck. I did the following on Mac Lion: - I took Pharo 1.4: http://gforge.inria.fr/frs/download.php/30620/Pharo-1.4-14438.zip - I ran it with CogNB: https://ci.lille.inria.fr/pharo/view/NativeBoost/job/NB-Cog-Mac-Cocoa/lastS… - I then executed: Gofer new squeaksource: 'Athens'; package: 'ConfigurationOfAthens'; load. ((Smalltalk at: #ConfigurationOfAthens) project version: '1.0') load. - Then: AthensDemoMorph new openInWorld But I get "Error: function unavailable" for: - #(#AthensCairoSurface #cairo_image_surface_create #(#int #aFormat #, #int #aWidth #, #int #aHeight)) - '/opt/local/lib/libcairo.2.dylib' See the attached log. I guess I am missing the cairo library. What should I do to get it?
