  17 # 18/01/2001 -  Cleanups
  18 #               Functions prototyped as foo(void) same as foo()
  19 #               Stop eval'ing where we don't need to.
  20 # -- huggie@earth.li
  21
  22 # 27/06/2001 -  Allowed whitespace after initial "/**" and
  23 #               allowed comments before function declarations.
  24 # -- Christian Kreibich <ck@whoop.org>
  25
  26 # Still to do:
  27 #       - add perldoc documentation
  28 #       - Look more closely at some of the scarier bits :)
  29
  30 # 26/05/2001 -  Support for separate source and object trees.
  31 #               Return error code.
  32 #               Keith Owens <kaos@ocs.com.au>
  33
  34 # 23/09/2001 - Added support for typedefs, structs, enums and unions
  35 #              Support for Context section; can be terminated using empty line
  36 #              Small fixes (like spaces vs. \s in regex)
  37 # -- Tim Jansen <tim@tjansen.de>
  38
  39 # 25/07/2012 - Added support for HTML5
  40 # -- Dan Luedtke <mail@danrl.de>

  45
  46 Read C language source or header FILEs, extract embedded documentation comments,
  47 and print formatted documentation to standard output.
  48
  49 The documentation comments are identified by "/**" opening comment mark. See
  50 Documentation/kernel-doc-nano-HOWTO.txt for the documentation comment syntax.
  51
  52 Output format selection (mutually exclusive):

  55   -html5                Output HTML5 format.
  56   -list                 Output symbol list format. This is for use by docproc.
  57   -man                  Output troff manual page format. This is the default.
  58   -rst                  Output reStructuredText format.

  60
  61 Output selection (mutually exclusive):
  62   -export               Only output documentation for symbols that have been
  63                         exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()
  64                         in any input FILE or -export-file FILE.
  65   -internal             Only output documentation for symbols that have NOT been
  66                         exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL()
  67                         in any input FILE or -export-file FILE.
  68   -function NAME        Only output documentation for the given function(s)
  69                         or DOC: section title(s). All other functions and DOC:
  70                         sections are ignored. May be specified multiple times.
  71   -nofunction NAME      Do NOT output documentation for the given function(s);
  72                         only output documentation for the other functions and
  73                         DOC: sections. May be specified multiple times.
  74
  75 Output selection modifiers:
  76   -no-doc-sections      Do not output DOC: sections.
  77   -enable-lineno        Enable output of #define LINENO lines. Only works with
  78                         reStructuredText format.
  79   -export-file FILE     Specify an additional FILE in which to look for
  80                         EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with
  81                         -export or -internal. May be specified multiple times.
  82
  83 Other parameters:
  84   -v                    Verbose output, more warnings and other information.
  85   -h                    Print this help.

  98 # (* @parameterx: (description of parameter x)?)*
  99 # (* a blank line)?
 100 #  * (Description:)? (Description of function)?
 101 #  * (section header: (section description)? )*
 102 #  (*)?*/
 103 #
 104 # So .. the trivial example would be:
 105 #
 106 # /**
 107 #  * my_function
 108 #  */
 109 #
 110 # If the Description: header tag is omitted, then there must be a blank line
 111 # after the last parameter specification.
 112 # e.g.
 113 # /**
 114 #  * my_function - does my stuff
 115 #  * @my_arg: its mine damnit
 116 #  *
 117 #  * Does my stuff explained.
 118 #  */
 119 #
 120 #  or, could also use:
 121 # /**
 122 #  * my_function - does my stuff
 123 #  * @my_arg: its mine damnit
 124 #  * Description: Does my stuff explained.
 125 #  */
 126 # etc.
 127 #
 128 # Besides functions you can also write documentation for structs, unions,
 129 # enums and typedefs. Instead of the function name you must write the name
 130 # of the declaration;  the struct/union/enum/typedef must always precede
 131 # the name. Nesting of declarations is not supported.
 132 # Use the argument mechanism to document members or constants.
 133 # e.g.
 134 # /**
 135 #  * struct my_struct - short description
 136 #  * @a: first member
 137 #  * @b: second member
 138 #  *
 139 #  * Longer description
 140 #  */

 142 #     int a;
 143 #     int b;
 144 # /* private: */
 145 #     int c;
 146 # };
 147 #
 148 # All descriptions can be multiline, except the short function description.
 149 #
 150 # For really longs structs, you can also describe arguments inside the
 151 # body of the struct.
 152 # eg.
 153 # /**
 154 #  * struct my_struct - short description
 155 #  * @a: first member
 156 #  * @b: second member
 157 #  *
 158 #  * Longer description
 159 #  */
 160 # struct my_struct {
 161 #     int a;
 162 #     int b;
 163 #     /**
 164 #      * @c: This is longer description of C
 165 #      *
 166 #      * You can use paragraphs to describe arguments
 167 #      * using this method.
 168 #      */
 169 #     int c;
 170 # };
 171 #
 172 # This should be use only for struct/enum members.
 173 #
 174 # You can also add additional sections. When documenting kernel functions you
 175 # should document the "Context:" of the function, e.g. whether the functions
 176 # can be called form interrupts. Unlike other sections you can end it with an
 177 # empty line.
 178 # A non-void function should have a "Return:" section describing the return
 179 # value(s).
 180 # Example-sections should contain the string EXAMPLE so that they are marked
 181 # appropriately in DocBook.
 182 #
 183 # Example:
 184 # /**
 185 #  * user_function - function that can only be called in user context
 186 #  * @a: some argument
 187 #  * Context: !in_interrupt()
 188 #  *
 189 #  * Some description
 190 #  * Example:
 191 #  *    user_function(22);
 192 #  */

 196 # All descriptive text is further processed, scanning for the following special
 197 # patterns, which are highlighted appropriately.
