doxy2man - Man Page

Create man pages from doxygen XML output.


doxy2man [Options]


Doxygen is great for generating HTML based API documentation. But the man page output mode of doxygen (GENERATE_MAN = YES) is not that awesome. Doxygen generates for a header file a man page with all functions, enums etc. For each structure it generates a man page listing all its (public) attributes. For C based projects this is not very useful, because one usually expects things like one man page for each function and referenced structs documented where used.

Doxy2man takes the XML generated by Doxygen as input and creates several man pages from that. It creates a summary man page for a header and for each function a detailed man page. The output is optimized for C projects. It supports the most common doxygen features, e.g. implicit and explicit see also tags, copyright, author information, brief and detailed descriptions, etc.


Create a small Doxygen configuration file. To enable XML output use something like this:

GENERATE_XML           = YES
XML_OUTPUT             = xml

Call doxygen:

$ doxygen

The xml subdirectory should contain some XML files now.

Call doxy2man:

$ ./doxy2man xml/myheader_8h.xml

View the man pages:

$ ls out
$ man -l out/my_header.h.3
$ man -l out/my_func_a.3
$ man -l out/my_func_b.3


Doxy2man implements several useful defaults but is also customizable:

$ ./doxy2man --help
Generates man pages from doxygen XML output
-h,     --help           this screen
        --nowarn         suppress warnings
        --nosummary      don't generate summare man page
        --nocopyright    don't generate copyright section
        --nofollow       don't parse referenced xml files
        --novalidate     don't validate xml files against compound.xsd
        --noseealsoall   don't add all functions under see also
        --nosort         don't sort functions under see also
        --nostructs      don't print structs in function man pages
-o DIR, --out DIR        output directory
-s STR, --section STR    man page section
        --short-pkg STR  short man page header/footer string, e.g. 'Linux'
        --pkg STR        man page header/footer string, e.g. 'Linux Programmer's Manual'
-i STR, --include STR    include path prefix
