C union are missing in classes/ output

[markand]

Given a following example of doxygen documentation:

#ifndef TEST_H
#define TEST_H

/**
 * \file test.h
 */

/**
 * \brief The foo struct.
 */
struct foo {
	int fa; /*!< Field 1. */
	int fb; /*!< Field 2. */
};

/**
 * \brief The baz union.
 */
union baz {
	int ba; /*!< Field 1. */
	int bb; /*!< Field 2. */
};

#endif

Using a plain default Doxyfile (just setting GENERATE_XML to Yes) and invoking doxybook2, it looks like union are missing from the output.

$ doxybook2 -i xml -o docs

It properly loads xml/unionbaz.xml from Doxygen and listed correctly in the files list:

$ grep baz docs/Files/test_8h.md 
| union | **[baz](Classes/unionbaz.md)** <br>The baz union.  |

But there is no files Classes/unionbaz.md generated though.

Thanks for spotting this bug.

It was only generating unions that belong to some class or namespace, not global ones.

Fixed in the new release releases/tag/v1.3.0
