Path reorder fails

[krummrey]

Whenever I try to reorder paths I get this error: Do I have to preprocess the file in some way?
Traceback (most recent call last): File "eggbot_reorder.py", line 170, in <module> e.affect() File "/Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/inkex.py", line 268, in affect self.effect() File "eggbot_reorder.py", line 149, in effect item = ( id, self.get_start_end( node, transform ) ) File "eggbot_reorder.py", line 108, in get_start_end sp = simplepath.parsePath( d ) File "/Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/simplepath.py", line 90, in parsePath token, isCommand = lexer.next() File "/Applications/Inkscape.app/Contents/Resources/share/inkscape/extensions/simplepath.py", line 31, in lexPath length = len(d) TypeError: object of type 'NoneType' has no len()

I have not seen this error, and I cannot seem to reproduce it, trying today on a new file.

This is likely due to an improperly formed SVG file, at least according to some definition of "improperly", according to Inkscape.

I would suggest trying the following, as a first pass:
Edit > Select all in all layers
Object > Ungroup (Possibly more than once, if you have nested groups in your file)
Path > Object to path

If converting all of your objects to paths does not work, I am very curious how the file was made. Does this have imported artwork? Do you have a procedure to replicate the issue from within Inkscape, starting with a new file?

If all else fails you might try to zip and send us the SVG file (by e-mail) so that we can examine and try to reproduce the issue.

The SVGs came all from Illustrator CS6. I had ungrouped them but for some reason I had to do the
Path > Object to path
to get it to work. Now it works like a charm.
Thanks for the suggestions.

My experience is identical with krummrey's - both the error and the positive results from oskay's suggested fix. Until I chanced to find this issue and solution in github, I had given up on using eggbot_reorder. I daresay others may have had this problem and given up also.

Since the fix is so simple and effective, I propose that when there is an error, eggbot_reorder.py should print oskay's instructions for attempting the fix. Demo svg file below, after proposed change:

Original:

    def get_start_end( self, node, transform ):
        """Given a node, return the start and end points"""
        d = node.get( 'd' )
        sp = simplepath.parsePath( d )

Suggested change:

    def get_start_end( self, node, transform ):
        """Given a node, return the start and end points"""
        d = node.get( 'd' )
        try:
            sp = simplepath.parsePath( d )
        except TypeError:
            inkex.errormsg  (
    'Internal error occurred, please try the following steps:\n\
    1.  Select all objects you want to reorder\n\
    2.  Ungroup [Object/Ungroup] (repeat until "Group" no longer appears in status line)\n\
    3.  Convert to path [Path/Object to Path]\n'
                            )

Here is a simple demo svg file which demonstrates the problem.
