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) | |

41 | # This will read a 'c' file and scan for embedded comments in the | |
42 | # style of gnome comments (+minor extensions - see below). | |
43 | # | |
44 | ||
45 | # Note: This only supports 'c'. | |
46 | ||
47 | # usage: | |
48 | # kerneldoc [ -docbook | -html | -text | -man ] | |
49 | # [ -function funcname [ -function funcname ...] ] c file(s)s > outputfile | |
50 | # or | |
51 | # [ -nofunction funcname [ -function funcname ...] ] c file(s)s > outputfile | |
52 | # | |
53 | # Set output format using one of -docbook -html -text or -man. Default is man. | |
54 | # | |
55 | # -function funcname | |
56 | # If set, then only generate documentation for the given function(s). All | |
57 | # other functions are ignored. | |
58 | # | |
59 | # -nofunction funcname | |
60 | # If set, then only generate documentation for the other function(s). All | |
61 | # other functions are ignored. Cannot be used with -function together | |
62 | # (yes thats a bug - perl hackers can fix it 8)) | |
63 | # | |
64 | # c files - list of 'c' files to process | |
65 | # | |
66 | # All output goes to stdout, with errors to stderr. | |
67 | ||
68 | # | |
69 | # format of comments. | |
70 | # In the following table, (...)? signifies optional structure. | |
71 | # (...)* signifies 0 or more structure elements | |
72 | # /** | |
73 | # * function_name(:)? (- short description)? | |
74 | # (* @parameterx: (description of parameter x)?)* | |
75 | # (* a blank line)? | |
76 | # * (Description:)? (Description of function)? | |
77 | # * (section header: (section description)? )* | |
78 | # (*)?*/ | |
79 | # | |
80 | # So .. the trivial example would be: | |
81 | # | |
82 | # /** | |
83 | # * my_function | |
84 | # **/ | |
85 | # | |
86 | # If the Description: header tag is ommitted, then there must be a blank line | |
87 | # after the last parameter specification. | |
88 | # e.g. | |
89 | # /** | |
90 | # * my_function - does my stuff | |
91 | # * @my_arg: its mine damnit | |
92 | # * | |
93 | # * Does my stuff explained. | |
94 | # */ | |
95 | # | |
96 | # or, could also use: | |
97 | # /** | |
98 | # * my_function - does my stuff | |
99 | # * @my_arg: its mine damnit | |
100 | # * Description: Does my stuff explained. | |
101 | # */ | |
102 | # etc. | |
103 | # | |
104 | # Beside functions you can also write documentation for structs, unions, | |
105 | # enums and typedefs. Instead of the function name you must write the name | |
106 | # of the declaration; the struct/union/enum/typedef must always precede | |
107 | # the name. Nesting of declarations is not supported. | |
108 | # Use the argument mechanism to document members or constants. | |
109 | # e.g. | |
110 | # /** | |
111 | # * struct my_struct - short description | |
112 | # * @a: first member | |
113 | # * @b: second member | |
114 | # * | |
115 | # * Longer description | |
116 | # */ | |

122 | # }; |
123 | # | |
124 | # All descriptions can be multiline, except the short function description. | |
125 | # | |
126 | # You can also add additional sections. When documenting kernel functions you | |
127 | # should document the "Context:" of the function, e.g. whether the functions | |
128 | # can be called form interrupts. Unlike other sections you can end it with an | |
129 | # empty line. | |
130 | # Example-sections should contain the string EXAMPLE so that they are marked | |
131 | # appropriately in DocBook. | |
132 | # | |
133 | # Example: | |
134 | # /** | |
135 | # * user_function - function that can only be called in user context | |
136 | # * @a: some argument | |
137 | # * Context: !in_interrupt() | |
138 | # * | |
139 | # * Some description | |
140 | # * Example: | |
141 | # * user_function(22); | |
142 | # */ | |
143 | # ... | |
144 | # | |
145 | # | |
146 | # All descriptive text is further processed, scanning for the following special | |
147 | # patterns, which are highlighted appropriately. | |
148 | # | |
149 | # 'funcname()' - function | |
150 | # '$ENVVAR' - environmental variable | |
151 | # '&struct_name' - name of a structure (up to two words including 'struct') | |
152 | # '@parameter' - name of a parameter | |
