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>

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