Re: [Pharo-users] Turn off auto-completion

by Marcus Denker

Hi, Yes, I don't like it either. The option is called "Smart Characters" in OCompletion. Maybe we shoud turn it off by default.

Turn off auto-completion

by Tim Johnson

Hi, I don't like how the browser/editor thinks it is smarter than me (even if it is). How do I completely turn off the "feature" of it inserting an extra ' whenever I myself type an ' ? I really, really hate that. I've gone through the preferences and tried turning off anything related to eCompletion and Shout, and I've tried changing the system default browser. The darn thing is still making me navigate around these extra 's which is just not how I code. I feel like I've asked this question here before, like two years ago. In any case, I again gave up and went back to Squeak which does not force this upon me. If it is your intention to allow users to turn this off, it would be nice to know how that is accomplished. Thanks again, Tim

Hello Igor, Thanks! It doesn't rotate the string draw. canvas drawString: 'Hello, World!' at: 40@40 font: nil color: (Color cyan).

Re: [Pharo-users] Code Critics for unloaded projects

by Bernat Romagosa

Ok I understand, and I guess modifying this would mean re-engineering the whole thing, right? Are there any alternatives around? Could you, for example, use Moose to analyse smalltalk code quality? I've heard about Chuck too, but I'm not sure the project is alive... Thanks!

Rotation in Canvas draws

by Andre Hora

Hello, I would like to know how to rotate (given a degree or an angle) the draws in a Canvas. For example: in FormCanvas class>>test1, how to draw the string (or the rectangle, or the oval) vertically instead of horizontally? FormCanvas class>>test1 ... canvas drawString: 'Hello, World!' at: 40@40 font: nil color: (Color cyan). canvas fillRectangle: ((10@80) corner: (31@121)) color: (Color magenta). canvas fillOval: ((10@80) corner: (31@121)) color: (Color cyan). ... thanks and regards, -- Andre Hora

Re: [Pharo-users] Code Critics for unloaded projects

by AxiNat

Dave, thanks a lot, I'm gonna try it right away. On the other topic, I'm not sure I completely understood what the problem is. Couldn't we write an extension to Code Critics that ran on unloaded code? In which ways would that break compatibility with other dialects? I think this functionality would be really neat for projects that deal with other smalltalk projects (like Squeaksource/Squeakhub), and as it's pretty crucial to my project I'm willing and able to put my time into it. The problem is I'm afraid my skills do not suffice to take on this project on my own, so any guidelines on how to proceed or who to address would be of great help :) Bernat Romagosa. 2011/4/4 David T.

Re: [Pharo-users] Code Critics for unloaded projects

by David T. Lewis

Bernat, OSProcess and CommandShell will work with a SqueakVM from http://www.squeakvm.org/unix/ so to solve your immediate problem you can use that VM. For background, a unix VM should include the OSProcess plugin, AIO plugin, and XDisplayControlPlugin. Cog VM's need some platform patches which may not yet have been integrated into the code base. With those patches in place, #forkSqueak will work on Cog, although the UI will not function for the forked image (but this is not a problem for many usages).
