Combining Recipe Robot with URLTextSearcher

Introduction

In this tutorial, we will explore how to integrate Recipe Robot with the URLTextSearcher processor. This combination is particularly useful when dealing with app download URLs that are version-specific but follow a predictable pattern. By the end of this guide, you will understand how to modify recipes in Recipe Robot to utilize URLTextSearcher effectively.

Step 1: Setting Up Recipe Robot

1. Install Recipe Robot

   • Clone the Recipe Robot repository from GitHub:

     git clone https://github.com/homebysix/recipe-robot.git
     

   • Navigate to the cloned directory:

     cd recipe-robot
     

   • Install the necessary dependencies.

2. Create a Basic Recipe

   • Start by creating a basic recipe using the Recipe Robot format. This typically includes specifying the app name, version, download URL, and other relevant metadata.
   • Example format:

     {
       "version": "1.0",
       "url": "https://example.com/download/v1.0/app.zip",
       "name": "MyApp"
     }
     

Step 2: Modifying the Recipe for URLTextSearcher

1. Identify the Download URL Pattern

   • Determine the pattern of the download URL. For example, if the URL structure is predictable (e.g., changing only the version number), note how the version is included in the URL.

2. Integrate URLTextSearcher

   • Modify the recipe to incorporate the URLTextSearcher processor. You will need to specify how the version number will be dynamically extracted and appended to the URL.
   • Example modified recipe:

     {
       "version": "1.0",
       "url": "{{urlTextSearcher}}",
       "name": "MyApp",
       "processors": [
         {
           "type": "URLTextSearcher",
           "url": "https://example.com/downloads",
           "pattern": "app-v(\\d+\\.\\d+\\.\\d+).zip"
         }
       ]
     }
     

   • Ensure to replace the URL and pattern with the actual values relevant to your application.

Step 3: Testing Your Recipe

1. Run the Recipe

   • Use Recipe Robot to run the modified recipe to see if it correctly fetches the download URL based on the specified pattern.
   • Execute the command in your terminal:

     recipe-robot run myapp.recipe.json
     

2. Verify the Output

   • Check the output to ensure that the correct URL is generated and that it matches the expected download link.

Conclusion

In this tutorial, we successfully combined Recipe Robot with URLTextSearcher to create a dynamic recipe that accommodates version-specific download URLs. By understanding how to modify and test your recipes, you can streamline the process of accessing app downloads. As a next step, consider exploring additional processors that can enhance your recipes further or experiment with different URL patterns.
