  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>

  43 # This will read a 'c' file and scan for embedded comments in the
  44 # style of gnome comments (+minor extensions - see below).
  45 #
  46
  47 # Note: This only supports 'c'.
  48
  49 # usage:
  50 # kernel-doc [ -docbook | -html | -html5 | -text | -man | -list ]
  51 #            [ -no-doc-sections ]
  52 #            [ -function funcname [ -function funcname ...] ]
  53 #            c file(s)s > outputfile
  54 # or
  55 #            [ -nofunction funcname [ -function funcname ...] ]
  56 #            c file(s)s > outputfile
  57 #
  58 #  Set output format using one of -docbook -html -html5 -text or -man.
  59 #  Default is man.
  60 #  The -list format is for internal use by docproc.
  61 #
  62 #  -no-doc-sections
  63 #       Do not output DOC: sections
  64 #
  65 #  -function funcname
  66 #       If set, then only generate documentation for the given function(s) or
  67 #       DOC: section titles.  All other functions and DOC: sections are ignored.
  68 #
  69 #  -nofunction funcname
  70 #       If set, then only generate documentation for the other function(s)/DOC:
  71 #       sections. Cannot be used together with -function (yes, that's a bug --
  72 #       perl hackers can fix it 8))
  73 #
  74 #  c files - list of 'c' files to process
  75 #
  76 #  All output goes to stdout, with errors to stderr.
  77
  78 #
  79 # format of comments.
  80 # In the following table, (...)? signifies optional structure.
  81 #                         (...)* signifies 0 or more structure elements
  82 # /**
  83 #  * function_name(:)? (- short description)?
  84 # (* @parameterx: (description of parameter x)?)*
  85 # (* a blank line)?
  86 #  * (Description:)? (Description of function)?
  87 #  * (section header: (section description)? )*
  88 #  (*)?*/
  89 #
  90 # So .. the trivial example would be:
  91 #
  92 # /**
  93 #  * my_function
  94 #  */
  95 #
  96 # If the Description: header tag is omitted, then there must be a blank line
  97 # after the last parameter specification.
  98 # e.g.
  99 # /**
 100 #  * my_function - does my stuff
 101 #  * @my_arg: its mine damnit
 102 #  *
 103 #  * Does my stuff explained.
 104 #  */
 105 #
 106 #  or, could also use:
 107 # /**
 108 #  * my_function - does my stuff
 109 #  * @my_arg: its mine damnit
 110 #  * Description: Does my stuff explained.
 111 #  */
 112 # etc.
 113 #
 114 # Besides functions you can also write documentation for structs, unions,
 115 # enums and typedefs. Instead of the function name you must write the name
 116 # of the declaration;  the struct/union/enum/typedef must always precede
 117 # the name. Nesting of declarations is not supported.
 118 # Use the argument mechanism to document members or constants.
 119 # e.g.
 120 # /**
 121 #  * struct my_struct - short description
 122 #  * @a: first member
 123 #  * @b: second member
 124 #  *
 125 #  * Longer description
 126 #  */
 127 # struct my_struct {
 128 #     int a;
 129 #     int b;
 130 # /* private: */
 131 #     int c;
 132 # };
 133 #
 134 # All descriptions can be multiline, except the short function description.
 135 #
 136 # You can also add additional sections. When documenting kernel functions you
 137 # should document the "Context:" of the function, e.g. whether the functions
 138 # can be called form interrupts. Unlike other sections you can end it with an
 139 # empty line.
 140 # A non-void function should have a "Return:" section describing the return
 141 # value(s).
 142 # Example-sections should contain the string EXAMPLE so that they are marked
 143 # appropriately in DocBook.
 144 #
 145 # Example:
 146 # /**
 147 #  * user_function - function that can only be called in user context
 148 #  * @a: some argument
 149 #  * Context: !in_interrupt()
 150 #  *
 151 #  * Some description
 152 #  * Example:
 153 #  *    user_function(22);
 154 #  */

 156 #

 159 # patterns, which are highlighted appropriately.

 162 # '$ENVVAR' - environmental variable
