Public bug reported:
Running 32-bit Ubuntu 16.04 from an eternal USB hard-drive attached to
an N110 netbook.
Here's the problem: the file-browser of the standard version of kturtle
from the Xenial repos (version 0.8.1 beta) doesn't find "*.turtle"-files
(which it somewhat oddly lists as ".*turtle"-files). To find your
"*.turtle"-files, you have to select "All files" from the file-browser
drop-down menu.
Also:
1. If you try to open a turtle file from a terminal with:
[code]
kturtle -i /path/file.turtle
[/code]
you get an error-message:
"Malformed URL /path/file.turtle."
Finally:
2. The ap will save a new "*.turtle"-file, but doesn't seem to register
that it has saved it. If you try to open a new turtle-script after
saving a script as a turtle-file, the ap notifies you that you are going
to lose the changes that you've just saved.
If you want to play around with kturtle, try pasting the code below into
the edit window. See if you can find it after you've saved it:
[code]
#script to draw a sequence of recursively-constructed branching pattern
#n determines the size of the pattern, p its position in the sequence
#take n = power of 2=<512, 1=<p=<7
#The script, below, consists of just one 'routine', activated with the command
"tree n, p", where 'n' and 'p' are parameters as previously described.
#This basic 'tree'-routine contains within it a number of 'internal'
sub-routines, also defined with the learn-command, and shown offset:
#"t1" draws the first pattern in the sequence
#"tp" draws the pth pattern (p>=2) as a line segment of length n/2 surmounted
by a "crown" of half-scale (p-1)th patterns
#a 'branch' sub-routine is also included to improve the symmetry of the final
design

Hope you grey-beards can fix this bug, ut if you can't, you at least got
to see a pretty picture.
