Current kernel-doc (perl) script generates this warning: Use of uninitialized value in concatenation (.) or string at scripts/kernel-doc line 1668. So explicitly check for SRCTREE in the ENV before using it, and then if it is set, append a '/' to the end of it, otherwise the SRCTREE + filename can (will) be missing the intermediate '/'.

w.o. 03-11-2000: added the '-filelist' option.
18/01/2001 - Cleanups
Functions prototyped as foo(void) same as foo()
Stop eval'ing where we don't need to.
-- huggie@earth.li
27/06/2001 - Allowed whitespace after initial "/**" and
allowed comments before function declarations.
-- Christian Kreibich ck@whoop.org
Still to do:
- add perldoc documentation
- Look more closely at some of the scarier bits :)
26/05/2001 - Support for separate source and object trees.
Return error code.
Keith Owens kaos@ocs.com.au
23/09/2001 - Added support for typedefs, structs, enums and unions
Support for Context section; can be terminated using empty line
Small fixes (like spaces vs. \s in regex)
-- Tim Jansen tim@tjansen.de
This will read a 'c' file and scan for embedded comments in the
style of gnome comments (+minor extensions - see below).
Note: This only supports 'c'.
usage:
kerneldoc [ -docbook | -html | -text | -man ]
[ -function funcname [ -function funcname ...] ] c file(s)s > outputfile
or
[ -nofunction funcname [ -function funcname ...] ] c file(s)s > outputfile
Set output format using one of -docbook -html -text or -man. Default is man.
-function funcname
If set, then only generate documentation for the given function(s). All
other functions are ignored.
-nofunction funcname
If set, then only generate documentation for the other function(s). All
other functions are ignored. Cannot be used with -function together
(yes thats a bug - perl hackers can fix it 8))
c files - list of 'c' files to process
All output goes to stdout, with errors to stderr.
format of comments.
In the following table, (...)? signifies optional structure.
(...)* signifies 0 or more structure elements
/**
* function_name(:)? (- short description)?
(* @parameterx: (description of parameter x)?)*
(* a blank line)?
* (Description:)? (Description of function)?
* (section header: (section description)? )*
()?/
So .. the trivial example would be:
/**
* my_function
**/
If the Description: header tag is ommitted, then there must be a blank line
after the last parameter specification.
e.g.
/**
* my_function - does my stuff
* @my_arg: its mine damnit
*
* Does my stuff explained.
*/
or, could also use:
/**
* my_function - does my stuff
* @my_arg: its mine damnit
* Description: Does my stuff explained.
*/
etc.
Beside functions you can also write documentation for structs, unions,
enums and typedefs. Instead of the function name you must write the name
of the declaration; the struct/union/enum/typedef must always precede
the name. Nesting of declarations is not supported.
Use the argument mechanism to document members or constants.
e.g.
/**
* struct my_struct - short description
* @a: first member
* @b: second member
*
* Longer description
*/
struct my_struct {
int a;
int b;
};
All descriptions can be multiline, except the short function description.
You can also add additional sections. When documenting kernel functions you
should document the "Context:" of the function, e.g. whether the functions
can be called form interrupts. Unlike other sections you can end it with an
empty line.
Example-sections should contain the string EXAMPLE so that they are marked
appropriately in DocBook.
Example:
/**
* user_function - function that can only be called in user context
* @a: some argument
* Context: !in_interrupt()
*
* Some description
* Example:
* user_function(22);
*/
...
All descriptive text is further processed, scanning for the following special
patterns, which are highlighted appropriately.
'funcname()' - function
'$ENVVAR' - environmental variable
'&struct_name' - name of a structure (up to two words including 'struct')
'@parameter' - name of a parameter
'%CONST' - name of a constant.
my $errors = 0; my $warnings = 0;
match expressions used to find embedded type information
my $type_constant = '%([-\w]+)'; my $type_func = '(\w+)()'; my $type_param = '@(\w+)'; my $type_struct = '&((struct\s*)?[\w]+)'; my $type_env = '($\w+)';
Output conversion substitutions.
One for each output format
these work fairly well
my %highlights_html = ( $type_constant, "$1", $type_func, "$1", $type_struct, "$1", $type_param, "$1" ); my $blankline_html = "
";
XML, docbook format
my %highlights_xml = ( "([^=])\"([^\"<]+)\"", "$1$2", $type_constant, "$1", $type_func, "$1", $type_struct, "$1", $type_env, "$1", $type_param, "$1" ); my $blankline_xml = "\n";
gnome, docbook format
my %highlights_gnome = ( $type_constant, "<replaceable class="option">$1", $type_func, "$1", $type_struct, "$1", $type_env, "$1", $type_param, "$1" ); my $blankline_gnome = "\n";
these are pretty rough
my %highlights_man = ( $type_constant, "$1", $type_func, "\\fB$1\\fP", $type_struct, "\\fI$1\\fP", $type_param, "\\fI$1\\fP" ); my $blankline_man = "";
text-mode
my %highlights_text = ( $type_constant, "$1", $type_func, "$1", $type_struct, "$1", $type_param, "$1" ); my $blankline_text = "";
sub usage { print "Usage: $0 [ -v ] [ -docbook | -html | -text | -man ]\n"; print " [ -function funcname [ -function funcname ...] ]\n"; print " [ -nofunction funcname [ -nofunction funcname ...] ]\n"; print " c source file(s) > outputfile\n"; exit 1; }
read arguments
if ($#ARGV==-1) { usage(); }
my $verbose = 0; my $output_mode = "man"; my %highlights = %highlights_man; my $blankline = $blankline_man; my $modulename = "Kernel API"; my $function_only = 0; my $man_date = ('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December')[(localtime)[4]] . " " . ((localtime)[5]+1900);
Essentially these are globals
They probably want to be tidied up made more localised or summat.
CAVEAT EMPTOR! Some of the others I localised may not want to be which
could cause "use of undefined value" or other bugs.
