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. Looks slick. It also hid or destroyed my iAddress category. All my code's under _UnpackagedPackage. The classes don't seem to be visible, though I can do a "Find class" and they'll show up with an "!" to their left. ===Blake===

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?

You have to install a browser with refactoring support, such as Nautilus. Open the configuration browser and load it from there :).

[Pharo-project] refactoring

by blake

OK, I've got a clean Pharo 1.4 (plus seaside) and need to refactor some code. I haven't changed the defaults. It looks like there are settings for refactoring, but I don't see how to actually invoke anything. I'm used to seeing the options in the context menu. ===Blake===
