Re: [Pharo-project] Nautilus and grey out text

If a package A adds an exteinson to a class from different package B then the extended class from package B is grayed out and all methods that are not part of the package A too. -- Pavel On Wed, Dec 12, 2012 at 10:03 AM, dimitris chloupis <thekilon(a)yahoo.co.uk>wrote: > I went through the Nautilus pdf and it seems to explains most of the thing > but the grey out text.

I would say: welcome to Pharo Smalltalk ;-) This is why/how we do it: keep on improving the infrastructure in small steps and sometimes replace big parts. The amount of things already done, being done and in the pipeline is really spectacular. And yes, Nautilus is really cool. -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] Nautilus and grey out text

by dimitris chloupis

I went through the Nautilus pdf and it seems to explains most of the thing but the grey out text. Any idea why some classess and methods are grey out ? By the way congratulation to Nautilus author and all people contributing to it , it certainly looksÂ like a big improvement over the classic system browser.

thank you , I will take a look.

Sure, we are interested. The most important (and difficult) thing is to create a Debian archive (.deb file). Nicolas Petton and I worked on that already but a lot of work remains to be done (e.g., making Pharo compilable by debian tools).

Re: [Pharo-project] Fwd: Lua scripting with nativeboost?

by Peter H. Meadows

I was thinking about making a MUD / MOO type game with pharo as the server and scripting language. Any ideas on how this should be done? How would you make sure the user scripts are sandboxed? Would you have an image running the server and a separate image for each user?

Re: [Pharo-project] Fwd: Lua scripting with nativeboost?

by Esteban Lorenzano

Why not use pharo itself? Scripting languages are used in static-typed systems as a way to avoid their complexity, so I understand clearly why c++ games provide lua (or python) as a script language... but I do not understand which benefit would bring using lua as a scriptiong on pharo (and yes, I do have gaming in mind). also, a non-programer will find a lot easier to learn pharo than lua.

[Pharo-project] Getting input from a pen tablet?

by Carla F. Griggio

Hi everyone! I hope this is a stupid thing that is just driving me crazy because of my * newbieness* on the subject, but if I evaluate this: Sensor tabletPoint I get a PrimitiveFailed error. The plugin needed for getting input from pen tablets is JoystickTabletPlugin and is an external plugin of Cog. What do I need to do to make that message work? Thanks! Carla.
