<overview>
|
|
<p>This rule identifies two files that have a lot of the same lines but with different variable and
|
|
method names. This makes it difficult to make changes in future and makes the code less easy to read.

<recommendation>
|
|
<p>It is important to determine why there are small differences in the files. Sometimes the files
|
|
might have been duplicates but an update was only applied to one copy. If this is the case it should
|
|
be simple to merge the files, preserving any changes.</p>
|
|
|
|
<p>If the files are intentionally different then it could be a good idea to consider extracting some
|
|
of the shared code into its own module and import that module into the original.</p>
