Getting the sketchbook / libraries path from within a sketch

in Programming Questions • 5 months ago

Any way to get it? I know there is the sketchPAth(""), but I need the sketchbook path to access some library configuration files that are inside that. It could also help a way to get a certain library's folder absolute path.

I've tried this, but says the path is "null":

import processing.app.*;

void setup(){

println("sketchbook.path "+Preferences.get("sketchbook.path"));

}

this?

println(sketchPath(""));

println(sketchPath);

println(dataPath(""));

Yes, I saw that functions. But I want to have is the sketchbook/libraries folder, independently of where the sketch is, so for any sketch in any subfolder or even outside the sketchbook, I can access to some of the library's data.

[global path]/SketchbookFolderName/libraries/MyLibrary/MyData/

I fear there is no simple, portable way for getting this information...
If it can be useful, you can see the path in the property sketchbook.path of the preferences.txt file, but the next problem is to locate this file!

Just get the path where the Class (of the library) is stored. then relative path from class to config file

URL main = LIBRARY_CLASS.class.getResource("LIBRARY_CLASS.class");

String tmp = main.getPath();

tmp = tmp.substring(0, tmp.indexOf('!'));

tmp = tmp.replace("file:/", "");

File f = new File(tmp);

if(!f.exists()){

System.err.println("Error");

}

f = f.getParentFile(); // go to where the config is stored

Thanks in_digo,

Hmm... goot hint indeed. It works with regular librarires (those with "include") but does not work with the library I want to configure: "voce" ( voce.sourceforge.net)...

URL main = SpeechInterface.class.getResource("SpeechInterface.class");

it gives the path to the sketch location, and I need the library location to configure it;

//the following initiates the voce library
voce.SpeechInterface.init(sketchPath("../../library"), true, true,sketchPath("gram"),"digits");

Ah, good trick, in_digo.
Tried with my library:

import org.philhosoft.p8g.svg.P8gGraphicsSVG;
import java.io.*;
import java.net.*;
void setup()
{
println(System.getProperty("user.dir"));
println(sketchPath);
println(System.getProperty("sketchbook.path")); // preference.txt content isn't given to PApplet
URL main = P8gGraphicsSVG.class.getResource("P8gGraphicsSVG.class");
String tmp = main.getPath();
tmp = tmp.substring(0, tmp.indexOf('!'));
tmp = tmp.replace("file:/", "");
File f = new File(tmp);
if (!f.exists()) {
System.err.println("Error");
}
f = f.getParentFile(); // go to where the config is stored
println(f);
exit();
}

Well it gives you the path to the class file, so if the library is not in the library dir but in the sketch dir it will give you the sketch dir of course. Since "voce" is not a processing library it depends where you put the files. But if you did not put the "voce" files in the library dir I dont get why you need the sketch folder to have access to the config files of "voce".

Right, my fault, I had a copy of the library inside the sketch folder
and it was loading that instead of the one in the
sketchbook/libraries.

It works now.

Thanks for the help!
