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# 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
187# '&struct_name' - name of a structure (up to two words including 'struct')
188# '@parameter' - name of a parameter

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# */
155# ...
156#
157#
158# All descriptive text is further processed, scanning for the following special
159# patterns, which are highlighted appropriately.
160#
161# 'funcname()' - function
162# '$ENVVAR' - environmental variable

164# '@parameter' - name of a parameter
