Spaces in file paths

[AdrianLazar]

Hi guys,

I'm having an issue using the fbximport command: if the fbx path contains spaces then houdini crashes, for example:

 

hou.hscript('fbximport $HIP/test e/test2.fbx') -> crash

hou.hscript('fbximport $HIP/test/test2.fbx') -> works fine

 

At first I thought that houdini doesn't support spaces in paths but if I use the fileSop to read a geometry file with spaces in the path that work perfectly fine.

 

Now I know there shouldn't be any spaces in folder names to begin with but that's something in this case I don't have any control over

 

Any help would be much appreciated,

Thanks!

i just tested in the textport and in Python shell you have to use for the Path =>"

 

the error comes because the hscript thinks the the filepath has ended where the space is. to solve this you have to put the filepath in to double quotes. 

 

this should work:

hou.hscript('fbximport "$HIP/test e/test2.fbx"')

Hi Francis,

Thanks for the quick reply, it worked fine in the test.

Unfortunately for the real implementation doesn't work since I need to generate file path from a parameter like this:

 

    _objecttodestroy = HDA.parm('objecttodestroy').eval()
    fbxtoimport = 'fbximport -m off ' + _objecttodestroy
    hou.hscript(fbxtoimport)

 

Thanks again,

-Adrian

Then this should work:

_objecttodestroy = HDA.parm('objecttodestroy').eval()
fbxtoimport = 'fbximport -m off "{}"'.format(_objecttodestroy)
hou.hscript(fbxtoimport)

Awesome, that works Petr! Could you explain me what is it doing to make it work?

 

Thanks!

It replaces {} with variable in .format(variable) method.
Because string is interpreted between single quotes ('some string') the double quotes inside that string are interpreted as part of the string ('some string "quoted" is still string')

a = 1
b = 'other text'
text = 'some text "{}" {}'.format(a,
print text

# for double quotes inside doube quotes we need escape character
text = "some text \"{}\" {}".format(a,
print text
