How To Install libhash-merge-perl on Debian 10
Introduction
In this tutorial we learn how to install libhash-merge-perl on Debian 10.
What is libhash-merge-perl
libhash-merge-perl is:
Hash::Merge merges two arbitrarily deep hashes into a single hash. That is, at any level, it will add non-conflicting key-value pairs from one hash to the other, and follows a set of specific rules when there are key value conflicts (as outlined below). The hash is followed recursively, so that deeply nested hashes that are at the same level will be merged when the parent hashes are merged. Please note that self-referencing hashes, or recursive references, are not handled well by this method.
Values in hashes are considered to be either ARRAY references, HASH references, or otherwise are treated as SCALARs. By default, the data passed to the merge function will be cloned using the Clone module; however, if necessary, this behavior can be changed to use as many of the original values as possible. (See set_clone_behavior).
