Problems due to unquoted initializers in C++ structs / classes

[g-braeunlich]

Given this example:

struct Example{
  int number = 1;
  bool logical = [](){ return true; }();
};

doxygen outputs this xml:

<?xml version='1.0' encoding='UTF-8' standalone='no'?>
<doxygen xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="compound.xsd" version="1.12.0" xml:lang="en-US">
  <compounddef id="structExample" kind="struct" language="C++" prot="public">
    <compoundname>Example</compoundname>
    <sectiondef kind="public-attrib">
      <memberdef kind="variable" id="structExample_1a09f7763a5fb31fea43835bbeee959437" prot="public" static="no" mutable="no">
        <type>int</type>
        <name>number</name>
        <initializer>= 1</initializer>
        ...
      </memberdef>
      <memberdef kind="variable" id="structExample_1a3bf3d46e677ff30a1aaaa087d8e3ce2c" prot="public" static="no" mutable="no">
        <type>bool</type>
        <name>logical</name>
        <initializer>= []() { return true; }()</initializer>
       ...
      </memberdef>
    </sectiondef>
    ...
  </compounddef>
</doxygen>

Which then gets translated to this md:

# Struct Example

[**ClassList**](annotated.md) **>** [**Example**](structExample.md)

## Public Attributes

| Type | Name |
| ---: | :--- |
|  bool | [**logical**](#variable-logical)   = = []() { return true; }()<br> |
|  int | [**number**](#variable-number)   = = 1<br> |
...

At this point 2 issues become visible:

• There is a duplicated = sign.
• The []() appears unquoted and thus will be interpreted as a md reference instead of code.

Suggestions:

• Strip leading / = chars from initializers when reading from xml.
• Quote all parsed initializer strings with md backticks before writing out to md

Hi, thank you for providing a detailed example. If you know how to fix it, feel free to make PR. I'll look at it first over the Christmas holidays.

Have a nice day, Jacob

Thanks for the quick reply. I already created a PR. I did not find any unit tests. Therefore I also did not write one for this use case.
If you still want some or if I violated some contributing guidelines, please let me know!
