Monospaced font
by KasperOsterbye Feb. 11, 2015

Feb. 11, 2015

And no, I do not want to restart the discussion of the (lack of) qualities regarding such fonts. It is just not clear to me how to get hold of a font. It seems like at the one hand it is all 'Bitmap deja vu sans regular'. In the settings browser I can pick all kinds of fonts, but it is unclear how I get a reference to them as I do not want to install the font as default or code fonts, but just need to apply the font to a few words in a Text object. If I try to ask for StrikeFont for say 'Courier' I get 'Bitmap deja vu sans regular'. Where is the magic hidden? A perhaps related question is if one can apply subscript and superscript to the regular Text attributes - I have not been able to find that either.

Installing Pharo on Ubuntu
by J.F. Rick Feb. 11, 2015

Feb. 11, 2015

I have a new computer and installed Ubuntu 14.10 on it. When I tried to install Pharo using the PPA instructions, it failed. I get the following message when executing "sudo apt-get update": W: Failed to fetch http://ppa.launchpad.net/pharo/stable/ubuntu/dists/utopic/main/binary-amd64… 404 Not Found W: Failed to fetch http://ppa.launchpad.net/pharo/stable/ubuntu/dists/utopic/main/binary-i386/… 404 Not Found I was able to get Pharo running with the Zeroconf script, but I thought I'd report that the standard thing didn't work. Is it just that a binary doesn't yet exist for 14.10. Cheers, Jeff -- Jochen "Jeff" Rick, Ph.D. http://www.je77.com/ Skype ID: jochenrick

Some debugger vars incorrectly displayed as nil
by Yuriy Tymchuk Feb. 11, 2015

Feb. 11, 2015

Hi, some from time to time some variables are shown in the debugger as nils, despite the fact that they are not (if you inspect them you get a value). Is it a known issue? By the way in âall temp varsâ itâs displayed fine, Iâll add screenshots: Uko

About AST instance variable naming
by stepharo Feb. 11, 2015

Feb. 11, 2015

Hi today during a lecture I was quite surprised to see the name of the AST variables. There is no easy way to see that a variable is a position in the text or a subtree. Example RBValueNode subclass: #RBArrayNode instanceVariableNames: 'left right statements periods' classVariableNames: '' category: 'AST-Core-Nodes' RBValueNode subclass: #RBBlockNode instanceVariableNames: 'left right colons arguments bar body scope' classVariableNames: '' category: 'AST-Core-Nodes' Annoying because you have always to think (yes I know I'm stupid not knowing by heart the tree structure) to know if you get a tree under your fingers. We can definitively better in terms of code habilitability. We cleaned the visitor and since then the code is much much much better. I would do the following RBValueNode subclass: #RBArrayNode instanceVariableNames: 'leftParenthesisPosition rightParenthesisPosition statements periodsPosition' classVariableNames: '' category: 'AST-Core-Nodes' I would be also ok with RBValueNode subclass: #RBArrayNode instanceVariableNames: 'leftPosition rightPosition statements periodsPosition' classVariableNames: '' category: 'AST-Core-Nodes' RBValueNode subclass: #RBBlockNode instanceVariableNames: 'leftPosition rightPosition colonsPosition arguments barPosition body scope' classVariableNames: '' category: 'AST-Core-Nodes'

14616 Package Tags causing Monticello merge conflict
by Ben Coman Feb. 11, 2015

Feb. 11, 2015

I just produced a rough proof of concept to fix this issue. Its not ready to integrate because I don't grasp the architecture. I just hacked and smashed around with the debugger until it worked. It ended up needing only two methods modified, so hopefully it nicely defines the problem for a knowledgeable person to produce a proper solution. About a dozen small issues (e.g. renaming packages) are dependent on this, so can anyone help out? cheers -ben

Spotter idea - exclusion filter and google search syntax
by Ben Coman Feb. 10, 2015

Feb. 10, 2015

Just a random idea for Spotter, being able to exclude items from the search using a hyphen/minus sign. I don't have a use case right now, but it "feels" right, so maybe one will turn up soon. Its a broadly used paradigm per google search ( https://support.google.com/mail/answer/7190?hl=en) Also, it would be useful to be able to search on multiple terms similar to a regular web search. A slightly contrived use case is that I want to investigate drag handling of morphs. So I guess entities will have the word "drag" and then maybe "handler" or "handle" but in which order? Will it be #dragHandler or #handleDrag or #handleEventDrag or #handlesMouseOverDragging: ? A single search term restricts me to having to guess and manually retry each possible order. Searching on "drag hand" and getting all possible ordering would be real nice. cheers -ben

Reducing the activity of the image
by Norbert Hartl Feb. 10, 2015

Feb. 10, 2015

I have an installation where a pharo powered hardware is used in a closed case. Over time that collects quite some heat. One reason for this is that the pharo vm is taking approx. 6% CPU all the time. The only thing that happens is network/sockets. I suspended the ui thread in the image but on this platform it doesn't help. Are there any tweaks to lower the polling and the activity of the image/vm even more? thanks, Norbert
