• Videoconverter.js simple help command not working in node.js

  13 juin 2014, par Vinz243

  I am trying tu run a basic help command with videoconverter.js

  eval(fs.readFileSync("./ffmpeg-all-codecs.js", "utf-8"))
  
  var result = ffmpeg_run({
  
    print: console.log,
  
    printErr: console.log,
  
    files: [],
  
    arguments: ["-h"],
  
    TOTAL_MEMORY: 268435456
  
    // Can play around with this option - must be a power of 2
  
    // TOTAL_MEMORY: 268435456
  
  });
  
  console.log(result);
  
  console.log("Done");

  And the output

  $ node test

• Generating test data – Introducing the Piwik Platform

  9 octobre 2014, par Thomas Steur — Development

  This is the next post of our blog series where we introduce the capabilities of the Piwik platform (our previous post was How to create a command). This time you’ll learn how to generate test data.

  Developers are developing on their local Piwik instance which usually does not contain useful data compared to a real Piwik installation in production (only a few test visits and a few tests users and websites). The ‘VisitorGenerator’ plugin lets you generate any number of visits, websites, users, goals and more. The generator makes sure there will be data for each report so you can easily test anything.

  Getting started

  In this series of posts, we assume that you have already installed Piwik. If not, visit the Piwik Developer Zone where you’ll find the Installation guide for developers.

  Installing the VisitorGenerator plugin

  The easiest way to install the plugin is by using the Marketplace in Piwik itself. It is accessible via Settings => Marketplace => Get new functionality. There you’ll find the plugin “VisitorGenerator” which you can install and activate in one click.

  If your Piwik instance is not connected to the internet you can download the plugin from the VisitorGenerator page on the Marketplace. Afterwards you can install the plugin by going to Settings => Marketplace => Uploading a plugin and uploading the previously downloaded ZIP file.

  If you have already installed the plugin make sure it is activated by going to Settings => Plugins.

  Generating websites

  After you have installed the plugin you can add as many websites as you need. This is useful for instance when you want to test something that affects many websites such as the ‘All Websites’ dashboard or the Websites manager. To generate any number of websites use the following command :

  ./console visitorgenerator:generate-website --limit=10

  This will generate 10 websites. If you need more websites simply specify a higher limit. In case you are wondering the names and URLs of the websites are randomly generated by the Faker PHP library.

  Generating goals

  In case you want to test anything related to Goals you should execute the following command :

  ./console visitorgenerator:generate-goals --idsite=1

  This will generate a few goals for the specified site. The generated goals are defined in a way to make sure there will be conversions when generating the visits in the next step.

  Generating visits

  To generate visits there are two possibilities. Either via the Piwik UI by going to Settings => Visitor Generator or by using the command line. The UI is a bit limited in generating visits so we recommend to use the command line. There you can generate visits as follows :

  ./console visitorgenerator:generate-visits --idsite=1

  This will generate many different visits for the current day. Don’t worry if it takes a while, it will insert quite a few visits by default.

  In case you want to generate visits for multiple days in the past as well you can specify the --days option.

  ./console visitorgenerator:generate-visits --idsite=1 --days=5

  Providing your own logs

  Half of the generated visits are randomly generated and half of the visits are based on real logs to make sure there is data for each report. If you want to generate visits based on your own logs for a more realistic testing just place your log files in the plugins/VisitorGenerator/data folder and make sure the file name ends with .log. You can find a few examples in the VisitorGenerator data folder.

  To generate visits based only on real log files then use the --no-fake option.

  ./console visitorgenerator:generate-visits --idsite=1 --no-fake

  All generated visits will come from the logs and no random visits nor random fake data will be used.

  Advanced features

  We are regularly adding new commands, tools and runtime checks to make your life as a developer easier. For instance you can also generate users and annotations. In the future we want to extend the plugin to create visits in the background to make sure there will be constantly new actions in the real time report.

  Are you missing any kind of generator or any other feature to make your life as a developer easier ? Let us know by email, we are listening !
