      Is anyone able to provide an example of a simple module that can parse/display a printf output on the mirror? I’m trying to do this but really struggling to understand how to. I can use fprintf to get to a file but that’s not much help to me either.

      Ideally I would like to printf a value that will then be displayed in my module on the mirror…

        @darrene in the node_helper you can do something like that

        const spawn = require('child_process').spawn;
        const ls = spawn('ls', ['-lh', '/usr']);
        
        ls.stdout.on('data', (data) => {
          console.log(`stdout: ${data}`);
        });
        
        ls.stderr.on('data', (data) => {
          console.log(`stderr: ${data}`);
        });
        
        ls.on('close', (code) => {
          console.log(`child process exited with code ${code}`);
        });

        Please create a github issue if you need help, so I can keep track

          Thanks so much @strawberry-3.141, that’s just what I needed to set me in the right direction. I’ll do a bit of reading and follow this approach,. I’ll be sure to post how I get on :)
