GASP Core

GASP error in Linux Ubuntu Netbook edition

Asked by tsavas

Hello,

I'm trying to learn Python and thats the primary reason I installed Ubuntu.

The GASP package does not currently support Windows so I think it would be smoother with Ubuntu on my netbook. Can someone running Ubuntu 10.10 and has GASP installed tell me if they can run the following code without issues:

Code:

from gasp import *

begin_graphics(800, 600, title="Catch", background=color.YELLOW)
set_speed(120)

ball_x = 10
ball_y = 300
ball = Circle((ball_x, ball_y), 10, filled=True)
dx = 4
dy = 1

while ball_x < 810:
    ball_x += dx
    ball_y += dy
    move_to(ball, (ball_x, ball_y))
    update_when('next_tick')

end_graphics()

----
for me, a yellow screen appears only for a second and then I get:

>>> from gasptry import *
Exception in thread QueueFeederThread (most likely raised during interpreter shutdown):

How did you install GASP? What version are you on? (it's recommended to
use the version from the repositories, "sudo apt-get install python-gasp")

when I do "sudo apt-get install python-gasp" I get the message that:

python-gasp is already the newest version.
The following packages were automatically installed and are no longer required:
  linux-headers-2.6.35-22 linux-headers-2.6.35-22-generic

As far as I remember I installed GASP via Ubuntu Software Center though.

The version I installed in Ubuntu Software Center shows 0.3.3-1 (python-gasp)

GASP download at http://dev.laptop.org/pub/gasp/downloads/ shows latest version as: 0.3.2

Python version on Ubuntu is Python 2.6.6 (r266:84292, Sep 15 2010, 15:52:39)

also how do I know which version of GASP I have currently installed?

Assuming you installed a .deb package (e.g. via apt-get or similar program)

$ *dpkg -l python-gasp*

should give you a bit of info... That command returns the following for me:

*ii python-gasp 0.3.3-1 procedural Python graphics library for beginning
programmers*

I was trying to run my scripts with "from gasptry import *" from within python.

When I tried typing "python gasptry" within terminal it actually worked.
