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 | ||
1b40c194 DL |
39 | # 25/07/2012 - Added support for HTML5 |
40 | # -- Dan Luedtke <mail@danrl.de> | |

46 | Read C language source or header FILEs, extract embedded documentation comments, | |
47 | and print formatted documentation to standard output. | |
48 | ||
49 | The documentation comments are identified by "/**" opening comment mark. See | |
50 | Documentation/kernel-doc-nano-HOWTO.txt for the documentation comment syntax. | |
51 | ||
52 | Output format selection (mutually exclusive): | |
53 | -docbook Output DocBook format. | |
54 | -html Output HTML format. | |
55 | -html5 Output HTML5 format. | |
56 | -list Output symbol list format. This is for use by docproc. | |
57 | -man Output troff manual page format. This is the default. | |
c0d1b6ee | 58 | -rst Output reStructuredText format. |
fadc0b31 JN |
59 | -text Output plain text format. |
60 | ||
61 | Output selection (mutually exclusive): | |
86ae2e38 JN |
62 | -export Only output documentation for symbols that have been |
63 | exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() | |
c9b2cfb3 | 64 | in any input FILE or -export-file FILE. |
86ae2e38 JN |
65 | -internal Only output documentation for symbols that have NOT been |
66 | exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() | |
c9b2cfb3 | 67 | in any input FILE or -export-file FILE. |
fadc0b31 JN |
68 | -function NAME Only output documentation for the given function(s) |
69 | or DOC: section title(s). All other functions and DOC: | |
70 | sections are ignored. May be specified multiple times. | |
71 | -nofunction NAME Do NOT output documentation for the given function(s); | |
72 | only output documentation for the other functions and | |
73 | DOC: sections. May be specified multiple times. | |
74 | ||
75 | Output selection modifiers: | |
76 | -no-doc-sections Do not output DOC: sections. | |
0b0f5f29 DV |
77 | -enable-lineno Enable output of #define LINENO lines. Only works with |
78 | reStructuredText format. | |
88c2b57d JN |
79 | -export-file FILE Specify an additional FILE in which to look for |
80 | EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with | |
81 | -export or -internal. May be specified multiple times. | |
