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>

42#
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# For really longs structs, you can also describe arguments inside the
137# body of the struct.
138# eg.
139# /**
140#  * struct my_struct - short description
141#  * @a: first member
142#  * @b: second member
143#  *
144#  * Longer description
145#  */
146# struct my_struct {
147#     int a;
148#     int b;
149#     /**
150#      * @c: This is longer description of C
151#      *
152#      * You can use paragraphs to describe arguments
153#      * using this method.
154#      */
155#     int c;
156# };
157#
158# This should be use only for struct/enum members.
159#
160# You can also add additional sections. When documenting kernel functions you
161# should document the "Context:" of the function, e.g. whether the functions
162# can be called form interrupts. Unlike other sections you can end it with an
163# empty line.
164# A non-void function should have a "Return:" section describing the return
165# value(s).
166# Example-sections should contain the string EXAMPLE so that they are marked
167# appropriately in DocBook.
168#
169# Example:
170# /**
171#  * user_function - function that can only be called in user context
172#  * @a: some argument
173#  * Context: !in_interrupt()
174#  *
175#  * Some description
176#  * Example:
177#  *    user_function(22);
178#  */
179# ...
180#
181#
182# All descriptive text is further processed, scanning for the following special
183# patterns, which are highlighted appropriately.
184#
185# 'funcname()' - function
186# '$ENVVAR' - environmental variable
