To get the more information about Doxygen, use the following command –
$ doxygen --help
The sample output should be like this-
Doxygen version 1.8.11 Copyright Dimitri van Heesch 1997-2015 You can use doxygen in a number of ways: 1) Use doxygen to generate a template configuration file: doxygen [-s] -g [configName] If - is used for configName doxygen will write to standard output. 2) Use doxygen to update an old configuration file: doxygen [-s] -u [configName] 3) Use doxygen to generate documentation using an existing configuration file: doxygen [configName] If - is used for configName doxygen will read from standard input. 4) Use doxygen to generate a template file controlling the layout of the generated documentation: doxygen -l [layoutFileName.xml] 5) Use doxygen to generate a template style sheet file for RTF, HTML or Latex. RTF: doxygen -w rtf styleSheetFile HTML: doxygen -w html headerFile footerFile styleSheetFile [configFile] LaTeX: doxygen -w latex headerFile footerFile styleSheetFile [configFile] 6) Use doxygen to generate a rtf extensions file RTF: doxygen -e rtf extensionsFile ........................................................................
To generate documentation of source code, use the following code-
$ doxygen -g sample_text.conf
In the above command, it has generated a file called sample_text.conf which contains the following code as shown below –
# Doxyfile 1.8.11 # This file describes the settings to be used by the documentation system # doxygen (www.doxygen.org) for a project. # # All text after a double hash (##) is considered a comment and is placed in # front of the TAG it is preceding. # # All text after a single hash (#) is considered a comment and will be ignored. # The format is: # TAG = value [value, ...] # For lists, items can also be appended using: # TAG += value [value, ...] # Values that contain spaces should be placed between quotes (\" \"). #--------------------------------------------------------------------------- # Project related configuration options #--------------------------------------------------------------------------- ..................................................................................
To generate the documentation, use the following command –
$ doxygen sample_text.conf
The sample output should be like this –

To browse the HTML-formatted documentation, use the following command –
$ cd html /html$ google-chrome index.html
The sample output should be like this –
