Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
Nested ``++if++``, ``++for++``, ``++for in++``, ``++while++``, ``++do while++`` and ``++switch++`` statements are a key ingredient for making what's known as "Spaghetti code".
|
|
|
|
Such code is hard to read, refactor and therefore maintain.
|
|
|
|
=== Noncompliant code example
|
|
|
|
With the default threshold of 3:
|
|
|
|
[source,swift]
|
|
----
|
|
if condition1 { // Compliant - depth = 1
|
|
/* ... */
|
|
if condition2 { // Compliant - depth = 2
|
|
/* ... */
|
|
for var i = 0; i < 10; i++ { // Compliant - depth = 3, not exceeding the limit
|
|
/* ... */
|
|
if condition4 { // Non-Compliant - depth = 4
|
|
if condition5 { // Depth = 5, exceeding the limit, but issues are only reported on depth = 4
|
|
/* ... */
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
