Hello group, I want to create a txt file with inkscape but I can't do it.

who can help me?

------------------------------------------------ prueba.py ----------------------------------

import inkex

class Greet(inkex.GenerateExtension):
    def run(self):
        file = open("C:/datos.txt", "w")
        file.write("Hola mundo")
        file.close()

------------------------------------------------ prueba.ink ----------------------------------

<?xml version="1.0" encoding="UTF-8"?>
<inkscape-extension xmlns="http://www.inkscape.org/namespace/inkscape/extension">
  <name>Prueba</name>
  <id>org.inkscape.tutorial.prueba</id>
  <effect>
    <effects-menu>
      <submenu name="Propios"/>
    </effects-menu>
  </effect>
  <script>
    <command location="inx" interpreter="python">myExtension/prueba.py</command>
  </script>
</inkscape-extension>
 

import inkex

class Greet(inkex.GenerateExtension):

    def generate(self):
        file = open("C:/Users/xps/datos.txt", "w")
        file.write("Hola mundo")
        file.close()

if __name__ == '__main__':
    Greet().run()
    
This will work.

However, the 'GenerateExtension' is used for a specific purpose (to return svg fragments)

Unless you need to I would just use a normal 'EffectExtension'

Normally, when writing to files you would use pythons 'with' statement to automatically close the file after writing.

-- Unless you want to use the file elsewhere in the code before closing.

I would make a small function with a try / except statement.

That way you can protect against invalid filepaths

import inkex

def save_text_to_file(self, string, filepath):

    try:
        with open(filepath, 'w') as my_file:
            my_file.write(string)
    except:
        inkex.errormsg(f'Cannot Write Text File {filepath}')

class WriteTextFile(inkex.EffectExtension):

    def add_arguments(self, pars):
        pass
    
    def effect(self):

        my_text = """Whether you are an illustrator, designer, web designer or just someone who needs to create some vector imagery, Inkscape is for you!

Flexible drawing tools
Broad file format compatibility
Powerful text tool
Bezier and spiro curves        
        """

        save_text_to_file(self, my_text, '/home/name/Documents/foo.txt')
        
if __name__ == '__main__':
    WriteTextFile().run()

Hi inklinea.

Many thanks. I added the lines of code you showed me and ran Inkscape in administrator mode and it can get the file. I am a beginner and I am doing some tests.

Many thanks

Hi inklinea.

Thanks to your help, I was able to create this code that saves the ID of the objects selected in Inkscape in a text file.

-------------------------------------------------- CODE-------------------------------------------------------------------

import inkex

class GetID(inkex.EffectExtension):
    def add_arguments(self, pars):
        pass # We don't need arguments for this extension

    def effect(self):
        # Crear una lista vacía para los ID de los objetos seleccionados
        ids = []

        for elem in self.svg.selection:
            ids.append(elem.get("id"))

        with open("C:/id_objects.txt", "w") as file:
            file.write(" ".join(ids))
        
if __name__ == '__main__':
    GetID().run()

Do not run Inkscape in Administrator mode.

You could quite easily make a mistake in Python and delete your hard drive !

Writing anything to C:\ which is the root of the operating system is something which is unusual and basically never done. 

That is why you had to use admin rights to do it. 

Is there are reason you want to save in C:\ and not to your user folder for example ? 

Hi, inklinea

There is no reason, it seemed faster to test the code. Thanks for your recommendation, I already changed the path for the file
