Customizing Doxygen output for an .ini configuration file - doxygen

Is there a way to customize the HTML output for an .ini configuration file with incorporated comments, as for example:
[MySection]
;This is an extensive description of MyParameter (possibly with #commands after semicolon?)
MyParameter=MyValue
Despite this is a special usage, I would like to have each parameter parsed/listed separately with description (and unit? and recommended value?). The file could also look like this:
[MySection]
;#brief A brief description
;#details A detailled description
;#unit cows (The physical unit of the parameter)
;#recommendedValue 5 cows
MyParameter=7
Currently, I'm including the .ini file with #include/#verbinclude - unfortunately, without syntax highlighting. Thanks.

OK, I'm assuming that you included the file using the FILE_PATTERNS tag, so that at least the file is listed in your documentation. Additionally you have to set EXTENSION_MAPPING tag to tell doxygen how to interpret this file. Unfortunately the INI file syntax is not supported by doxygen. At this point you have two possibilities:
Writing a custom input-filter (e.g. in perl) and add this as INPUT_FILTER
Varying the comments so that the doxygen parser gets a valid code corresponding to the programming language you have defined in EXTENSION_MAPPING.
For example if you have set EXTENSION_MAPPING = ini=C Then your inifile should look like this:
;/// #file myinifile.ini
;/// #brief A brief description.
;/// #details A detailled description.
;/// #unit cows (The physical unit of the parameter)
;/// #recommendedValue 5 cows
MyParameter=7
;
The additional slashes /// are needed to tell the doxygen parser that this line is a comment line which shall be processed by the doxygen.
Also note the last semicolon ; which is needed since the doxygen C parser is expecting a closing ; after each declaration.

Having mainpage in HTML output only and not in LaTeX

I've got a mainpage using a HTML table that I only want to be included in the HTML output of doxygen. It should not be included in the other outputs (currently only LaTeX).
Since that mainpage uses doxygen commands like \ref and \mainpage itself, the \htmlonly tag is unfortunately not an option.
Is there a way to limit a markup file to certain outputs only?
As suggested, I ended up running doxygen twice, once for HTML output and once for LaTeX output. This gives me the flexibility to change other settings for different outputs as well, which is also something I was looking at.
So the dox file for my mainpage now looks like
/**
\if MySpecialFlagForHTMLOnly
\mainpage notitle
...
\endif
**/
My default doxyfile has GENERATE_HTML = YES and GENERATE_LATEX = NO. It also defines MySpecialFlagForHTMLOnly in ENABLED_SECTIONS.
Now for a second automated run, I change both GENERATE_HTML and GENERATE_LATEX and clear MySpecialFlagForHTMLOnly from ENABLED_SECTIONS.

Doxygen: how to include a markdown page to document a group

I have a rather complex project and I want to document it using doxygen.
I have no problem documenting the code and I also managed to have a nice front-page using a custom README.md file coupled with "USE_MDFILE_AS_MAINPAGE = README.md" directive in Doxyfile.
I defined several groups (#defgroup) which show up as "Modules" in my documentation.
I would like to add a "main page" to each of the group giving general information, beside the customary function/variable/type documentation.
I tried adding custom MODULENAME.md files coupled with matching #includedoc MODULENAME.md entries in group definition, it seem to work (I see several lines like: "Generating docs for page md_mcu_noitr_coro_README..."), but I cannot find if and where the page is linked (I expected to see it in the "Detailed Description" for the module, as it happens if I put some documentation inline where I put the "#includedoc" directive.
a snippet of one of my modules is:
/**
* #file coro.h
* #brief definition of coroutine implementing functions.
*
* #date: Feb 8, 2018
* #author: myself
*
* #defgroup coro "Coroutine implementation in plain 'C'."
*
* #includedoc mcu_noitr/coro/README.md
* #{
*
*/
What am I doing wrong?
Note: it is also a bit surprising I need to put the whole path from where my Doxyfile is, otherwise doxygen won't find it even if it's right beside the file containing the #includedoc command.
I also came across the problem that included files with Markdown formatted text via \includedoc or \include{doc} does not result in correctly interpreted Markdown. Note that I included Markdown files from other Markdown files. My work-around was to use the C pre-processor (cpp) - which is widely available - on Markdown files and use it's #include directive. You could of course use a true general text processor such as M4 as suggested in the cpp man page. Set FILTER_PATTERNS in Doxyfile as:
FILTER_PATTERNS = *.md="cpp -P -traditional-cpp"
You'll need the -P option to avoid it outputting line markers, which confuses Doxygen. -traditional-cpp was needed to avoid cpp eating white space that is important for the correct interpretation of Markdown. Don't use single quotes as this results in an error when Doxygen calls cpp via sh.
Then in my Markdown main page:
Main Page {#mainpage}
==========
Blah blah blah.
#include "other.md"
Using FILTER_PATTERNS instead of INPUT_FILTER avoids the problem about not being allowed to add or remove lines.
I have my markdown files in the same directory, I would guess that if they are located in different places you could tell cpp about it via -I, which would address your expectations about include paths on the issue you filed.
At the moment doxygen does not consider the fact that commands like \includedoc can contain markdown code. At the moment the only possibility would be to write a filter, see configuration parateter INPUT_FILTER in the doxygen configuration file, (not tested!) to replace the \includedoc` with the code of that file.

disable auto link in Doxygen

If I write some URL in source code comments like:
/**
* Here is an inline link [test](http://www.test.com).
* More information:
* test
*/
I enabled GENERATE_XML in Doxygen. This is what it generates:
<para>Here is an inline link [test](<ulink url="http://www.test.com">http://www.test.com</ulink>).
More information:
<ulink url="http://www.test.com">test</ulink> </para>
After converting the tags, I can create a Markdown content like:
Here is an inline link [test](http://www.test.com).
More information:
test
Note that the Markdown link [test](http://www.test.com) is polluted, which will break the link after I feed this into another Markdown processor. I need this as I want to write some markdown in comments, and extract it to some structured data formats for other tools to processing the markdown. I have disabled MARKDOWN_SUPPORT in Doxygen.
I have tried disable AUTOLINK_SUPPORT in doxyfile, but it can only disable internal type link to class/method/...
Solution for the mentioned problem, auto linking a web address, is to use [test](%http://www.test.com). By means of the % sign the (automatic) linking is suppressed.
In the documentation, paragraph "Step 3: Documenting the sources":
Links are created for words corresponding to documented classes (unless the word is preceded by a %; then the word will not be linked and the % sign is removed).
Note: in the above quote the wording is only for classes but it does work on other places as well. The same "problem" occurs in other places:
Description of AUTOLINK_SUPPORT
FAQ Doxygen automatically generates a link to the class MyClass somewhere
in the running text. How do I prevent that at a certain place?

Paragraph "\%"

Include an external .md file in a docblock?

There are doxygen commands #include, #htmlinclude, #verbinclude and the rest of the family. Each of them is equivalent to inlcuding the file inline and surrounding it with a pair of start and end tags like #code, #htmlonly, #verbatim etc.
For the life of me, I cannot find the doxygen command equivalent to just pasting a markdown file into the docblock without surrounding it with any tags that modify the interpretation of the included fragment.
Is this possible? How?

Doxygen \cite producing empty bibliography

I'm trying to use \cite in Doxygen to produce a bibliography page and also a reference within my text. I have bibtex in my search path and a proper .bib file. I have added the .bib file to CITE_BIB_FILES and am using a proper BibTex label found in the .bib file. Doxygen is creating a bibliography page, but it is empty. It is also creating a citation link in the documentation text, but the link is also empty. Any idea how I can get the citation info displayed?
I was facing the same problem. There is an perl dependency to generate citation. So you must have both perl and bibtex in the system path.
Ignore the example above, that only applies to Latex, for doxygen use (Note: no braces):
\cite Hale
The .bib file has to be located in doxygen working directory.
Bibliographic References HTML page will be then produced by doxygen with:
[1]J. K. Hale. Theory of functional–differential equations. Springer–Verlag, Berlin–Heidelberg–New York, 1977.
for the following bib entry:
#BOOK{Hale,
author = "J. K. Hale",
title = "Theory of functional--differential equations",
publisher = "Springer--Verlag, Berlin--Heidelberg--New York",
year = 1977
}
In order for \cite to work properly you need:
be sure to put your file.bib in the working directory where you call doxygen Doxyfile
bibtex executable must be in the search path
perl executable must be in the search path
the RefName used in \cite RefName must have a corresponding entry in file.bib
Maybe a little late, but I had the same problem. Doxygen generated a bibliography for LaTeX output, but not for HTML output and none of the proposed answers worked for me.
As suggested by #Raffi, this seems to be a bug in Doxygen < 1.8.3. I used Doxygen 1.8.1.1 and it did not work. Then I installed Doxygen 1.8.3.1 without changing anything else and it worked fine.
When you set CITE_BIB_FILES in DoxyFile did you include the .bib extension on the filename?
Doxygen claims it will automatically add the .bib extension, but if you omit it doxygen seems to gets confused and doesn't generate the citelist.doc file properly.
Include .bib in the filename and it should work fine, at least that is the case for me.
In order to create a bibliography you need to instal Perl, and add it to the search path, along with bibtex. In the documentation
for CITE_BIB_FILES it says:
"The CITE_BIB_FILES ... To use this feature you need bibtex and perl available in the search path ... "
