#19 Save dialog should append .sk

[Gregor Hoffleit]

I'd like to forward this request
(http://bugs.debian.org/109225) by a Debian user, Thimo
Neubauer <thimo@debian.org>:

"It would be great, if the save-dialog appended the
suffix ".sk" if no suffix is given"

Sounds like a valid suggestion to me.

It would also make sense if the SaveAs dialog would change
the suffix from .sk to .svg or .pdf or .ai to match the
"Files of type" button as it is changed. I incorrectly
assumed the output format would be governed by this button
instead of the suffix. (from 0.6.13)

About appending .sk:

Personally, I don't like programs appending suffixes to
filenames automagically, so I didn't do that in Sketch. I
wouldn't have a problem with doing that in this particular
case (i.e. append .sk when the filename doesn't have an
extension), if that's what the users prefer.

About depending on the extension to determing the file
format:

Unfortunately, the only information Sketch gets from Tk's
file dialog is the filename. Information about the selected
file format is not available. Possible fixes would be to try
to get at that information anyway if possible (which seems a
bit unlikely and it might be very tk version specific) or to
implement a new Filedialog (or reuse an old one from Tkinter
from before Tk had a file dialog IIRC). Neither solution is
very elegant and there's probably nobody with the time or
inclination to implement either of these.
