00030 /*
00031  * Usage:
00032     ansi2knr [--filename FILENAME] [INPUT_FILE [OUTPUT_FILE]]
00033  * --filename provides the file name for the #line directive in the output,
00034  * overriding input_file (if present).
00035  * If no input_file is supplied, input is read from stdin.
00036  * If no output_file is supplied, output goes to stdout.
00037  * There are no error messages.
00038  *
00039  * ansi2knr recognizes function definitions by seeing a non-keyword
00040  * identifier at the left margin, followed by a left parenthesis, with a
00041  * right parenthesis as the last character on the line, and with a left
00042  * brace as the first token on the following line (ignoring possible
00043  * intervening comments and/or preprocessor directives), except that a line
00044  * consisting of only
00045  *  identifier1(identifier2)
00046  * will not be considered a function definition unless identifier2 is
00047  * the word "void", and a line consisting of
00048  *  identifier1(identifier2, <<arbitrary>>)
00049  * will not be considered a function definition.
00050  * ansi2knr will recognize a multi-line header provided that no intervening
00051  * line ends with a left or right brace or a semicolon.  These algorithms
00052  * ignore whitespace, comments, and preprocessor directives, except that
00053  * the function name must be the first thing on the line.  The following
00054  * constructs will confuse it:
00055  *  - Any other construct that starts at the left margin and
00056  *      follows the above syntax (such as a macro or function call).
00057  *  - Some macros that tinker with the syntax of function headers.

00065     lpd 2000-04-12 backs out Eggert's changes because of bugs:
00066     - concatlits didn't declare the type of its bufend argument;
00067     - concatlits didn't recognize when it was inside a comment;
00068     - scanstring could scan backward past the beginning of the string; when
00069     - the check for \ + newline in scanstring was unnecessary.
00070 
00071     2000-03-05  Paul Eggert  <eggert@twinsun.com>
00072 
00073     Add support for concatenated string literals.
00074     * ansi2knr.c (concatlits): New decl.
00075     (main): Invoke concatlits to concatenate string literals.
00076     (scanstring): Handle backslash-newline correctly.  Work with
00077     character constants.  Fix bug when scanning backwards through
00078     backslash-quote.  Check for unterminated strings.
00079     (convert1): Parse character constants, too.
00080     (appendline, concatlits): New functions.
00081     * ansi2knr.1: Document this.
00082 
00083     lpd 1999-08-17 added code to allow preprocessor directives
00084         wherever comments are allowed
00085     lpd 1999-04-12 added minor fixes from Pavel Roskin
00086         <pavel_roskin@geocities.com> for clean compilation with
00087         gcc -W -Wall
00088     lpd 1999-03-22 added hack to recognize lines consisting of
00089         identifier1(identifier2, xxx) as *not* being procedures
00090     lpd 1999-02-03 made indentation of preprocessor commands consistent
00091     lpd 1999-01-28 fixed two bugs: a '/' in an argument list caused an
00092         endless loop; quoted strings within an argument list
00093         confused the parser
00094     lpd 1999-01-24 added a check for write errors on the output,
00095         suggested by Jim Meyering <meyering@ascend.com>
00096     lpd 1998-11-09 added further hack to recognize identifier(void)
00097         as being a procedure
00098     lpd 1998-10-23 added hack to recognize lines consisting of
00099         identifier1(identifier2) as *not* being procedures
00100     lpd 1997-12-08 made input_file optional; only closes input and/or
00101         output file if not stdin or stdout respectively; prints
00102         usage message on stderr rather than stdout; adds
00103         --filename switch (changes suggested by
00104         <ceder@lysator.liu.se>)
00105     lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with
00106         compilers that don't understand void, as suggested by
00107         Tom Lane
00108     lpd 1996-01-15 changed to require that the first non-comment token
00109         on the line following a function header be a left brace,
00110         to reduce sensitivity to macros, as suggested by Tom Lane
00111         <tgl@sss.pgh.pa.us>
00112     lpd 1995-06-22 removed #ifndefs whose sole purpose was to define
00113         undefined preprocessor symbols as 0; changed all #ifdefs
00114         for configuration symbols to #ifs
00115     lpd 1995-04-05 changed copyright notice to make it clear that
00116         including ansi2knr in a program does not bring the entire
00117         program under the GPL
00118     lpd 1994-12-18 added conditionals for systems where ctype macros
00119         don't handle 8-bit characters properly, suggested by
00120         Francois Pinard <pinard@iro.umontreal.ca>;
00121         removed --varargs switch (this is now the default)
00122     lpd 1994-10-10 removed CONFIG_BROKETS conditional
00123     lpd 1994-07-16 added some conditionals to help GNU `configure',
00124         suggested by Francois Pinard <pinard@iro.umontreal.ca>;
00125         properly erase prototype args in function parameters,
00126         contributed by Jim Avera <jima@netcom.com>;
00127         correct error in writeblanks (it shouldn't erase EOLs)
