I have used Prolog DCGs to mess around with this kind of thing, and if you have a lot of control over the input and your expectations you can make progress with a tool for formal languages, but if you want to do something sophisticated or support arbitrary inputs, you're probably wasting your time. -- Daniel Lyons

Re: [Pharo-users] Roassal Sunburst examples not working

by Arturo Zambrano

Hi All, I moved to Pharo3. The same error. I figured out that sunburst needed an Athens canvas. I figure out how to configure that evaluating: ROPlatform setCurrent: 'athens' The visualization shows up!!, but as soon as I pass the mouse cursor in front of the visualization window, I get a red window saying that: StrikeFont does not understand #glyphRendererOn: 1) Due to sunburst is platform dependent I suggest to add some check in order to inform the user that it needs Athens instead of morphic canvas. 2) Any hint on how to fix the #glyphRendererOn: MNU ? I found that FreeType and Logical fonts implement that message, but I cannot figure out how to tell Roassal to use such fonts.

Have you started with more basic examples e.g. "Morph new openInWorld"? There are some great examples on the old Squeak wiki, especially about layout. They probably still work on latest pharo. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Nautilus-error-tp4741184p4741232.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Donât worry. :) > I have been playing with Moose (version 4.8), mainly because I want to experiment with PetitParser. I am struggling a bit, but getting somewhere I think. I have been trying out a lot of snippets in a workspace, before getting down to producing proper code. In a fit of madness, thinking I was closing a debugger window, I closed the workspace window. It looks as though I have lost the contents, though I can probably reconstruct them from the changes file. My main Smalltalk experience is with Dolphin Smalltalk, and there, if you try to close a workspace, it asks if you want to save the contents first. Could Pharo have something similar? Normally it should. Now what I suggest is - use a class side methods like that you can version your scripts for free. > - or am I the only idiot to do this? > > As a supplementary point, I am trying to use PetitParser to parse natural language.

Re: [Pharo-users] Nautilus error

by Nicolai Hess

which pharo version? Yes, in Pharo2 this does not work anymore. And in Pharo3 there is not even a HierarchyBrowser anymore. In both versions, you can - use Nautilus to browse the class and select the "Hierarchy"-Button or - SystemNavigation default browseHierarchy:Boolean or - Boolean browseHierarchy Nicolai 2014-02-03 Bob Williams <rwilliams19(a)cox.net>: > I am trying to understand Morphs by looking at how the Workspace and > Browsers are created; however, I get a Nautilus error when I "DoIt" on the > following HierarchyBrowser newFor: Boolean.

Nautilus error

by Bob Williams

I am trying to understand Morphs by looking at how the Workspace and Browsers are created; however, I get a Nautilus error when I "DoIt" on the following HierarchyBrowser newFor: Boolean. That code is in the comments section for that class. Does the HierarchyBrowser no longer work or am I doing something wrong?
