I am creating a custom library for processing, and I am trying to create a txt file to store some basic txt.
In eclipse I have been using:
PrintWriter writer = new PrintWriter("storage.txt", "UTF-8");
writer.println("Some text");
writer.close();
But in processing it does not create a file, even when the sketch is saved. Is there a way I can create a file in the library section, that I can call in the processing IDE, because half the methods I try work in Eclipse but not in processing
output = createWriter("/data/" + folderPath + "/" + counter + "/"+ location);
//println("new folderpath " + folderPath + counter + "\\" + location);
file = dataFile(folderPath + location);
filePath = file.getPath();
filePath = filePath.replace(location, "");
try {
FileWriter fw = new FileWriter(file, true);///true = append
BufferedWriter bw = new BufferedWriter(fw);
output = new PrintWriter(bw);
}
catch(IOException ioe) {
System.out.println("Exception ");
ioe.printStackTrace();
println(filePath);
}
then
output.flush(); // Writes the remaining data to the file
output.close(); // Finishes the file
I think that should allow you to write
