[Pharo-project] Memory usage

by jannik.laval

Dear pharoers, We are loading really big models in the Moose software analysis platform. This generate a lot of small objects and with the biggest model, we approach the limit of 2Gb of the VM. Is it possible for anyone who knows the VM to add extra memory space ? Going to 4Gb or maybe 8Gb would be a great thing. Thank you for your help. Cheers, --- Jannik Laval

[Pharo-project] Strange behavior of Metacello in Pharo 2.0

by Alexandre Bergel

Hi! I've just downloaded a configuration using monticello browser. In a workspace I am doing: -=-=-=-=-=-=-=-=-= ConfigurationOfVersionner project -=-=-=-=-=-=-=-=-= and apparently Pharo tries to get something from http://www.squeaksource/MetacelloRepository , which utterly fail. I am using the last Pharo from the forge. Is there something obvious I am missing? Am I the only one to experience this?

[Pharo-project] shortcut to copy inside class comment does not work

by Mariano Martinez Peck

Hi guys. If with Nautilus you click in the class comments, and try to copy a piece of text from the comment with cmd+c it does not work! But it works if I do it from the menu. So I guess it is a problem with the shortcuts... cheers, -- Mariano http://marianopeck.wordpress.com

Re: [Pharo-project] [ANN] Alternative view of a system browser

by Camillo Bruni

We will have almost exactly that browser, very soon in Pharo :) I built an internal FileSystem which eventually will be used for versioning. Using the standard FileBrowser from Pharo on the internal FS delivers a very similar experience (albeit less code focused) as your example :) On 2012-07-21, at 08:55, Fernando Olivero wrote: > Hi, nice work.

Re: [Pharo-project] athens for strikefonts

by Tudor Girba

For the time being, StrikeFonts are the default fonts in Pharo. Given that it is the default it is used in practice all the time, and thus if we want Athens to be adopted easily we need support for the default case. The other solution is to change the default fonts, but this implies that we need to rethink how we distribute it, too, and I guess this will take a while.

Hi Doru, I am missing why StrikeFonts is so important for Moose. Is it the font used in all other the system?
