• deep-merge

Adds support for deep merges to =Hash=

#+BEGIN_SRC crystal

normal merge

{ "a" => { "b" => 4 } }.merge({ "a" => { "c" => true } }) => { "a" => { "c" => true } }

deep merge

{ "a" => { "b" => 4 } }.deep_merge({ "a" => { "c" => true } }) => { "a" => { "b" => 4, "c" => true } } #+END_SRC

• Installation

Add it to =shards.yml= in your project:

#+BEGIN_SRC yaml dependencies: deep-merge: gitlab: peterhoeg/deep-merge.cr #+END_SRC

• Usage

#+BEGIN_SRC crystal require "deep-merge" #+END_SRC

=Hash= is now monkey-patched to support =.deep_merge= and =.deep_merge!= instance methods.

** TODO Add support for:

• arrays (probably configurable) #+BEGIN_SRC crystal { "a" => [ "b" ] }.deep_merge({ "a" => [ "c" ] }) => { "a" => [ "b", "c" ] } #+END_SRC
• arrays of Hashes
