Migrate Process Vardump

Often used for debugging, this module takes any data given to it and dumps it to the terminal output and then passes it on. This is very useful when you’re writing migrations!

See the README for more details.

Requirements
* Drupal 8 or 9

Usage Use like any other process plugin:

field_my_field: - plugin: some_plugin source: my_source - plugin: vardump - plugin: some_other_plugin If it gets confusing, you can specify a "header" to display before the vardump:

field_my_field: - plugin: vardump source: my_source header: 'Before some_plugin' - plugin: some_plugin - plugin: vardump header: 'After some_plugin' - plugin: some_other_plugin The vardump process plugin acts as a passthrough. It does not modify the field value in the pipeline.

This Module is Part of a Migration Framework This module is part of a migration framework created for a client project in which we migrated information from Digital Measures to a Drupal site. However, the specific problems each module solves are common to migration processes in general. With the exception of Digitalmeasures Migrate, these modules are fairly generic and can be used for a variety of other migrations.

For more information on how this framework was used for a Digital Measure Migration, read:

* Case Study: University of Minnesota’s Provost Office

Here are the modules in the migration framework:


* Digitalmeasures Migrate Provides a method to access Digital Measures API through Drupal.
* Migrate Process XML Reads XML and allows you to extract particular key sections using XPath.
* Migrate Process S3 Allows you to download objects from an S3 bucket as files to your Drupal site.
* Migrate Process URL Allows you to manipulate URL values that are provided within the data.
* Migrate Process Regex Provides a way to use Regular Expressions in a Drupal migration.
* Migrate Process Vardump Often used for debugging, this module takes any data given to it and dumps it to the terminal output and then passes it on.
* Migrate Process Skip Provides a few different mechanisms to define what is “empty” and should be skipped.
* Migrate Process Trim This module provides a quick and simple means to remove leading or trailing characters (such as spaces) in a Drupal migration.
* Migrate Process Array Provides utilities for interacting with arrays during migration.
