Re: [Pharo-users] Copy/past doesn't work sometimes

by Peter UhnÃ¡k

Today I found out that if I have running xclipboard in the background pasting works properly even from Chromium. The problem is that it's a GUI app and will store everything that I've copied unless manually deleted. But you can give it a shot. Haven't really tested how it deals with non-text content (images). Also I tried to dig a little bit into how it is handled inside Pharo, but it is somewhere deep in VM. :( However middle-click pasting doesn't work but that seem to be simply a limitation of Pharo (My guess is because it is only supported by Linux and not Windows/Mac?).

I've seen something similar (ROOrthoVerticalLineShape), however nothing of that sort in Roassal2. I would imagine it to behave similarly to RTBezierLine - having controllingElements to specify the corners. (While ROOrtholines did it automatically I was looking for something more manual, so it can go in both directions - thus the controllingElements). > > Second thing I wasn't able to figure out is whether it is possible to create line from element to itself. All *AttachPoint classes aren't really able to cope with that. The best result I got was from Vertical/Horizontal AttachPoints (combined with BezierLine), however I would like to be able to specify which side it would start on and end on. Ideally not just middle of sides, but arbitrary part of the shape (I imagine that might be hard for non-rectangular shapes). > > Thanks, > Peter

Re: [Pharo-users] Copy/past doesn't work sometimes

by Peter UhnÃ¡k

I have the same problem on Debian, on both Pharo 3 and 4. I think that Chromium is doing something weird when copying to clipboard, because every other program I've tried works just fine. As a workaround I've installed clipboard manager and I copy from there (or paste and re-copy in some other text editor currently opened). Linux has multiple clipboards (at least one when copying text and one for currently selected text), so maybe Chromium uses the wrong one, or Pharo is checking only one?

Re: [Pharo-users] [Article] Elegant Pharo Code

by Offray Vladimir Luna CÃ¡rdenas

Sven, Thanks for your articles. I really like the approach and the idea of starting with more problem oriented writting (making a game is more project oriented, which is also fine by the way, just a complementary approach I prefer more). I would add myself to the HernÃ¡n's suggestion of using visualization to explain Smalltalk better, of course this could not be appropriate for on liners, but could be used in future post of your blog. I have thought about this myself[1] and made some small experiments[2] and in some sense Pharo seems a richer environment that even IPython [1] http://mutabit.com/offray/static/blog/output/posts/pharo-by-visualization.h… [2] http://mutabit.com/offray/static/blog/output/posts/borrachos-bochinche-futb… [3] http://mutabit.com/mutabit/default/wiki/ipython-deepness I would write a (Dyna)booklet on "Visual Data Narratives using Pharo Smalltalk" but for that I need to bootstrap my writing process inside Pharo by making tools that support outlining which is my best way to organize my writing[3]. That's where I'm now and in the process I hope to bootstrap myself from mailing list lurker and newbie to a more active member of this community. Your blog post are a good inspiration in this pad.

How to upload code from local cache to SmalltalkHub (It was Tree/Outliners of playgrounds, markdown inside comments and some quick medium size dreams for Pharo/Smalltalk)

Hi Alexandre, Thanks for your answer. I would see the Moose option as soon as I have proper access (these days this site and Tudor's home page are having problems). Meanwhile I have another questions for the community. I have created a local repository in the cache and I have setup an empty project on Smalltalk Hub. How can I synchronize them both?

Copy/past doesn't work sometimes
