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

45 | Usage: $0 [OPTION ...] FILE ... | |
46 | ||
47 | Read C language source or header FILEs, extract embedded documentation comments, | |
48 | and print formatted documentation to standard output. | |
49 | ||
50 | The documentation comments are identified by "/**" opening comment mark. See | |
51 | Documentation/kernel-doc-nano-HOWTO.txt for the documentation comment syntax. | |
52 | ||
53 | Output format selection (mutually exclusive): | |
54 | -docbook Output DocBook format. | |
55 | -html Output HTML format. | |
56 | -html5 Output HTML5 format. | |
57 | -list Output symbol list format. This is for use by docproc. | |
58 | -man Output troff manual page format. This is the default. | |
59 | -rst Output reStructuredText format. | |
60 | -text Output plain text format. | |
61 | -none Do not output documentation, only warnings. | |
62 | ||
63 | Output selection (mutually exclusive): | |
64 | -export Only output documentation for symbols that have been | |
65 | exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() | |
66 | in any input FILE or -export-file FILE. | |
67 | -internal Only output documentation for symbols that have NOT been | |
68 | exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() | |
69 | in any input FILE or -export-file FILE. | |
70 | -function NAME Only output documentation for the given function(s) | |
71 | or DOC: section title(s). All other functions and DOC: | |
72 | sections are ignored. May be specified multiple times. | |
73 | -nofunction NAME Do NOT output documentation for the given function(s); | |
74 | only output documentation for the other functions and | |
75 | DOC: sections. May be specified multiple times. | |
76 | ||
77 | Output selection modifiers: | |
78 | -no-doc-sections Do not output DOC: sections. | |
79 | -enable-lineno Enable output of #define LINENO lines. Only works with | |
80 | reStructuredText format. | |
81 | -export-file FILE Specify an additional FILE in which to look for | |
82 | EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with | |
83 | -export or -internal. May be specified multiple times. | |
84 | ||
85 | Other parameters: | |
86 | -v Verbose output, more warnings and other information. | |
87 | -h Print this help. | |
88 | ||
89 | EOF | |
90 | print $message; | |

95 | # format of comments. | |
96 | # In the following table, (...)? signifies optional structure. | |
97 | # (...)* signifies 0 or more structure elements | |
98 | # /** | |
99 | # * function_name(:)? (- short description)? | |
100 | # (* @parameterx: (description of parameter x)?)* | |
101 | # (* a blank line)? | |
102 | # * (Description:)? (Description of function)? | |
103 | # * (section header: (section description)? )* | |
104 | # (*)?*/ | |
105 | # | |
106 | # So .. the trivial example would be: | |
107 | # | |
108 | # /** | |
109 | # * my_function | |
110 | # */ | |
111 | # | |
112 | # If the Description: header tag is omitted, then there must be a blank line | |
113 | # after the last parameter specification. | |
114 | # e.g. | |
115 | # /** | |
116 | # * my_function - does my stuff | |
117 | # * @my_arg: its mine damnit | |
118 | # * | |
119 | # * Does my stuff explained. | |
120 | # */ | |
121 | # | |
122 | # or, could also use: | |
123 | # /** | |
124 | # * my_function - does my stuff | |
125 | # * @my_arg: its mine damnit | |
126 | # * Description: Does my stuff explained. | |
127 | # */ | |
128 | # etc. | |
129 | # | |
130 | # Besides functions you can also write documentation for structs, unions, | |
131 | # enums and typedefs. Instead of the function name you must write the name | |
132 | # of the declaration; the struct/union/enum/typedef must always precede | |
133 | # the name. Nesting of declarations is not supported. | |
134 | # Use the argument mechanism to document members or constants. | |
135 | # e.g. | |
136 | # /** | |
137 | # * struct my_struct - short description | |
138 | # * @a: first member | |
139 | # * @b: second member | |
140 | # * | |
141 | # * Longer description | |
142 | # */ | |
143 | # struct my_struct { | |
144 | # int a; | |
145 | # int b; | |
146 | # /* private: */ | |
147 | # int c; | |
148 | # }; | |
149 | # | |
150 | # All descriptions can be multiline, except the short function description. | |
151 | # | |
152 | # For really longs structs, you can also describe arguments inside the | |
153 | # body of the struct. | |
154 | # eg. | |
155 | # /** | |
156 | # * struct my_struct - short description | |
157 | # * @a: first member | |
158 | # * @b: second member | |
159 | # * | |
160 | # * Longer description | |
161 | # */ | |
162 | # struct my_struct { | |
163 | # int a; | |
164 | # int b; | |
165 | # /** | |
166 | # * @c: This is longer description of C | |
167 | # * | |
168 | # * You can use paragraphs to describe arguments | |
169 | # * using this method. | |
170 | # */ | |
171 | # int c; | |
172 | # }; | |
173 | # | |
174 | # This should be use only for struct/enum members. | |
175 | # | |
176 | # You can also add additional sections. When documenting kernel functions you | |
177 | # should document the "Context:" of the function, e.g. whether the functions | |
178 | # can be called form interrupts. Unlike other sections you can end it with an | |
179 | # empty line. | |
180 | # A non-void function should have a "Return:" section describing the return | |
181 | # value(s). | |
182 | # Example-sections should contain the string EXAMPLE so that they are marked | |
183 | # appropriately in DocBook. | |
184 | # | |
185 | # Example: | |
186 | # /** | |
187 | # * user_function - function that can only be called in user context | |
188 | # * @a: some argument | |
189 | # * Context: !in_interrupt() | |
190 | # * | |
191 | # * Some description | |
192 | # * Example: | |
193 | # * user_function(22); | |
194 | # */ | |
195 | # ... | |
196 | # | |
197 | # | |
198 | # All descriptive text is further processed, scanning for the following special | |
199 | # patterns, which are highlighted appropriately. | |
200 | # | |
201 | # 'funcname()' - function | |
202 | # '$ENVVAR' - environmental variable | |
203 | # '&struct_name' - name of a structure (up to two words including 'struct') | |
204 | # '&struct_name.member' - name of a structure member | |
205 | # '@parameter' - name of a parameter | |
206 | # '%CONST' - name of a constant. | |
207 | # '``LITERAL``' - literal string without any spaces on it. | |
