Convert - Reverse - Flip Backslash \ to a Forwardslash / hscript

[LaidlawFX]

Hello,

 

I'm using Hscript for some paths in Houdini and some of the global variables on windows are coming in as Backslashes \ and for some uses I need them as Forwardslashes / in Houdini and \ backslashes outside of Houdini.

 

Is there a way to change the forward slash to a back slash? Unfortunately backslash is an escape character...

http://www.sidefx.com/docs/houdini13.0/commands/_guide#idm47064707811440

 

Example

C:\Windows

needs to be

C:/Windows

 

As silly as this is in order to convert the other way this is the method i have, but doesn't work in the reverse

`strreplace(strreplace("C:\Windows","/","\ ")," ","")`

 

Thanks

-Ben

 

Edit: mistyped forward instead of back

Forward slash is not an escape character.

Sorry said it backwards backslash is the escape character...

For forward to backward slash is this conversion a bit simplier:

echo `strreplace("/project/project.hip", "/", "\\")`

For other direction I'm more comfortable with python:

echo `pythonexprs("str('c:\project\project.hip').replace('\\','/')")`

Hey Petr,

Thanks for the help, one last question for this then, if you don't mind.

 

Would you know why something like this wouldn't evaluate?

echo `pythonexprs("str(expandString('chs("mypath")')).replace('\\','/')")`

with chs("mypath") == c:\project\project.hip

 

I'm at the unfortunate situation to be half between languages at this point.

 

Thanks again

You are welcome, for python it needs to be:

hou.expandString('`chs("mypath")`')

(hou is Houdini python module, and there are extra backticks around chs())
But this hscript(python(hscript)) seems to be a little bit complicated for evaluation.

Once in python stay in python:

echo `pythonexprs("str(hou.parm('/obj/geo1/null1/mypath').eval()).replace('\\','/')")`

Where mypath is string parameter on the null1 node.
For evaluating on the same node you can use something like this in hscript expression:

`(pythonexprs("str(hou.pwd().parm('mypath').eval()).replace('\\','/')"))`

Where pwd() return current node.

Remember that you can also use

>>> import os
>>> os.path.normpath("C:\\\Windows/System32//oobe\/\/\/info\\\\//////backgounds")
'C:\\Windows\\System32\\oobe\\info\\backgrounds'

to fix mixed slashes problem and always get "\\" from environment variables or any path. Edited May 6, 2014 by mantragora

Thanks guys. Stuff worked out, well. Now for the big adventure, the full python conversion...
