| # 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: |
| # kernel-doc [ -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). |
| # Cannot be used together with -function |
| # (yes, that's 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; |
| # /* private: */ |
| # int c; |
| # }; |
| # |
| # 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. |
