File Path with backslashes

whodah

Hello,

I'm new to this. I'm using a Windows system and am tweaking the nifty SVG plugin:
http://flightsofideas.net/?p=572

It has a line in the code of:


@svgFilename = Sketchup.active_model.get_attribute "foi_svg_export", "svgFilename", "flightofideas.svg"

When one invokes the plugin, a pop-up box comes up with that path for the "Output File":
http://www.flickr.com/photos/27621953@N02/3768086037/

When first invoked, that path is simply "flightofideas.svg" until you specify (or navigate) a path. Subsequent changes remember that path. I'd like to automate that a bit and default that field to the drawing's working path to get you started. So far, from this post, I am at:


@svgFilename = Sketchup.active_model.get_attribute "foi_svg_export", "svgFilename", File.dirname(mymodel.path)+mymodel.title+".svg"

But instead of "C:/users/user/desktop/Untitled.svg" I get "C:usersuserdesktopUntitled.svg" (note the lack of slashes)

Also, I have a feeling that I'll need to add a slash on my own after the path and before the model. But I can't seem to get that working either.

Any ideas/help?

Thanks!

Try
File.join(File.dirname(mymodel.path), mymodel.title+".svg").tr("\\","/")
OR even the clunkier
(File.dirname(mymodel.path)+"/"+mymodel.title+".svg").tr("\\","/")
It you don't tell your code what to do it won't do it

BUT note how the path part will automatically contain separator slashes - which on a PC these are \ NOT /.
So it could be that the \ slashes in the path are getting things confused in the dialog code, so try the 'tr' conversion of \ to / - the / will work fine for both PC or MAC, and in js, webdialogs etc...
EDIT: Typo corrected to .tr("\\","/") TIG.

Maybe it would be logical to convert input file paths as early as possible to the Ruby notation, namely
mymodelpath = File.expand_path(mymodel.path) File.join(File.dirname(mymodelpath), mymodel.title+".svg")
This way you never have both delimiters at the same time, and by using Ruby's method %(#000000)[File.expand_path] your script is truely platform-agnostic (which is better than hardcoding delimiters for 1, 2, etc. platforms).

Hi,

I realize that I forgot to mention that I am defining mymodel as:


mymodel = Sketchup.active_model

TIG: thanks! I hear ya on the \ vs. / thing for windows. But / is what the SVG script shows on the screen when one chooses a path, even on this windows environment. I tried both:


File.join(File.dirname(mymodel.path), mymodel.title+".svg").tr("\"","/")

and:


(File.dirname(mymodel.path)+"/"+mymodel.title+".svg").tr("\"","/")

which both resulted in:
C:usersuserdesktop/Untitled.svg

Aerilius: that did the trick, thank you very much!

Your code results in:
C:/users/user/desktop/Untitled.svg

(and it works with the SVG plugin!)

Final code that works for those googling down the road:


mymodel = Sketchup.active_model
mymodelpath = File.expand_path(mymodel.path)
@svgFilename = Sketchup.active_model.get_attribute "foi_svg_export", "svgFilename", File.join(File.dirname(mymodelpath), mymodel.title+".svg")

TIG's example:
.tr("\"","/")
means replace all double quotes with a slash.

It probably should be:
.tr("\\","/")

Dan thanks for spotting my typo. I've corrected the original... By coincidence I was doing some changes between double and single quotes and it got stuck in my muscle memory !
