Hello everybody! I typed at Sage Notebook:

a = animate([circle((i,i), 1-1/(i+1), hue=i/10) for i in srange(0,2,0.2)], xmin=0,ymin=0,xmax=2,ymax=2,figsize=[2,2])
a.show()

I got the message:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "_sage_input_9.py", line 10, in <module>
    exec compile(u'open("___code___.py","w").write("# -*- coding: utf-8 -*-\\n" + _support_.preparse_worksheet_cell(base64.b64decode("YSA9IGFuaW1hdGUoW2NpcmNsZSgoaSxpKSwgMS0xLyhpKzEpLCBodWU9aS8xMCkgZm9yIGkgaW4gc3JhbmdlKDAsMiwwLjIpXSwgeG1pbj0wLHltaW49MCx4bWF4PTIseW1heD0yLGZpZ3NpemU9WzIsMl0pCmEuc2hvdygp"),globals())+"\\n"); execfile(os.path.abspath("___code___.py"))

    savefile = sage.misc.misc.graphics_filename(ext='gif')
AttributeError: 'module' object has no attribute 'graphics_filename'

Please help me to understand what went wrong. What is missing? Thanks.

This works for me at the command line, but you are right that in the notebook it doesn't, and there definitely isn't graphics_filename() in sage.misc.misc. This must be a recent regression, I think, as it works in Sage 5.3. The bug is at line 457 of the animate file, where it calls the gif method in the notebook, which is clearly wrong now. (Line 557 also calls this nonexistent function.)

For now, I'd suggest doing

sage: a.save(filename='circle.gif')

which works for me on sagenb.org.

Edit: the fix will be easy enough, see Trac ticket 13807.

Thanks a lot! I will check it on my work computer on Monday.

Notice that #13807 now has positive review, and if we're lucky will get into Sage 5.5.
