Perltidy Change Log
     You can help Perltidy evolve into a better program.  If you 
     have hit a bug, unusual behavior, annoyance, or have a suggested
     improvement, please send a note to perltidy at users.sourceforge.net.

     -Corrected a bug in which a break was not being made after a full-line
     comment within a short eval/sort/map/grep block.  A flag was not being
     zeroed.  The syntax error check catches this.  Here is a snippet which
     illustrates the bug:

            eval {
                #open Socket to Dispatcher
                $sock = &OpenSocket;
            };

     The formatter mistakenly thought that it had found the following 
     one-line block:
 
            eval {#open Socket to Dispatcher$sock = &OpenSocket; };

     The patch fixes this. Many thanks to Henry Story for reporting this bug.

     -Changes were made to help diagnose and resolve problems in a
     .perltidyrc file: 
       (1) processing of command parameters has been into two separate
       batches so that any errors in a .perltidyrc file can be localized.  
       (2) commands --help, --version, and as many of the --dump-xxx
       commands are handled immediately, without any command line processing
       at all.  
       (3) Perltidy will ignore any commands in the .perltidyrc file which
       cause immediate exit.  These are:  -h -v -ddf -dln -dop -dsn -dtt
       -dwls -dwrs -ss.  Thanks to Wolfgang Weisselberg for helpful
       suggestions regarding these updates.

     -Syntax check has been reinstated as default for MSWin32 systems.  This
     way Windows 2000 users will get syntax check by default, which seems
     like a better idea, since the number of Win 95/98 systems will be
     decreasing over time.  Documentation revised to warn Windows 95/98
     users about the problem with empty '&1'.  Too bad these systems
     all report themselves as MSWin32.

  2001 10 16

     -Fixed tokenization error in which a method call of the form

        Module::->new();
 
      got a space before the '::' like this:

        Module ::->new();

      Thanks to David Holden for reporting this.
 
     -Added -html control over pod text, using a new abbreviation 'pd'.  See
     updated perl2web man page. The default is to use the color of a comment,
     but italicized.  Old .css style sheets will need a new line for
     .pd to use this.  The old color was the color of a string, and there
     was no control.  
 
     -.css lines are now printed in sorted order.

     -Fixed interpolation problem where html files had '$input_file' as title
     instead of actual input file name.  Thanks to Simon Perreault for finding
     this and sending a patch, and also to Tobias Weber.

     -Breaks will now have the ':' placed at the start of a line, 
     one per line by default because this shows logical structure
     more clearly. This coding has been completely redone. Some 
     examples of new ?/: formatting:

           OLD:
                wantarray ? map( $dir::cwd->lookup($_)->path, @_ ) :
                  $dir::cwd->lookup( $_[0] )->path;

           NEW:
                wantarray 
                  ? map( $dir::cwd->lookup($_)->path, @_ )
                  : $dir::cwd->lookup( $_[0] )->path;

           OLD:
                    $a = ( $b > 0 ) ? {
                        a => 1,
                        b => 2
                    } : { a => 6, b => 8 };

           NEW:
                    $a = ( $b > 0 )
                      ? {
                        a => 1,
                        b => 2
                      }
                      : { a => 6, b => 8 };

        OLD: (-gnu):
        $self->note($self->{skip} ? "Hunk #$self->{hunk} ignored at 1.\n" :
                    "Hunk #$self->{hunk} failed--$@");

        NEW: (-gnu):
        $self->note($self->{skip} 
                    ? "Hunk #$self->{hunk} ignored at 1.\n"
                    : "Hunk #$self->{hunk} failed--$@");

        OLD:
            $which_search =
              $opts{"t"} ? 'title'   :
              $opts{"s"} ? 'subject' : $opts{"a"} ? 'author' : 'title';

        NEW:
            $which_search =
              $opts{"t"} ? 'title'
              : $opts{"s"} ? 'subject'
              : $opts{"a"} ? 'author'
              : 'title';
 
     You can use -wba=':' to recover the previous default which placed ':'
     at the end of a line.  Thanks to Michael Cartmell for helpful
     discussions and examples.  

     -Tokenizer updated to do syntax checking for matched ?/: pairs.  Also,
     the tokenizer now outputs a unique serial number for every balanced
     pair of brace types and ?/: pairs.  This greatly simplifies the
     formatter.

     -Long lines with repeated 'and', 'or', '&&', '||'  will now have
     one such item per line.  For example:

        OLD:
            if ( $opt_d || $opt_m || $opt_p || $opt_t || $opt_x
                || ( -e $archive && $opt_r ) )
            {
                ( $pAr, $pNames ) = readAr($archive);
            }

        NEW:
            if ( $opt_d
                || $opt_m
                || $opt_p
                || $opt_t
                || $opt_x
                || ( -e $archive && $opt_r ) )
            {
                ( $pAr, $pNames ) = readAr($archive);
            }

       OLD:
            if ( $vp->{X0} + 4 <= $x && $vp->{X0} + $vp->{W} - 4 >= $x
                && $vp->{Y0} + 4 <= $y && $vp->{Y0} + $vp->{H} - 4 >= $y ) 

       NEW:
            if ( $vp->{X0} + 4 <= $x
                && $vp->{X0} + $vp->{W} - 4 >= $x
                && $vp->{Y0} + 4 <= $y
                && $vp->{Y0} + $vp->{H} - 4 >= $y )

     -Long lines with multiple concatenated tokens will have concatenated
     terms (see below) placed one per line, except for short items.  For
     example:

       OLD:
            $report .=
              "Device type:" . $ib->family . "  ID:" . $ib->serial . "  CRC:"
              . $ib->crc . ": " . $ib->model() . "\n";

       NEW:
            $report .= "Device type:"
              . $ib->family . "  ID:"
              . $ib->serial . "  CRC:"
              . $ib->model()
              . $ib->crc . ": " . "\n";

     NOTE: at present 'short' means 8 characters or less.  There is a
     tentative flag to change this (-scl), but it is undocumented and
     is likely to be changed or removed later, so only use it for testing.  
     In the above example, the tokens "  ID:", "  CRC:", and "\n" are below
     this limit.  

     -If a line which is short enough to fit on a single line was
     nevertheless broken in the input file at a 'good' location (see below), 
     perltidy will try to retain a break.  For example, the following line
     will be formatted as:
 
        open SUM, "<$file"
          or die "Cannot open $file ($!)";
 
     if it was broken in the input file, and like this if not:

        open SUM, "<$file" or die "Cannot open $file ($!)";

     GOOD: 'good' location means before 'and','or','if','unless','&&','||'

     The reason perltidy does not just always break at these points is that if
     there are multiple, similar statements, this would preclude alignment.  So
     rather than check for this, perltidy just tries to follow the input style,
     in the hopes that the author made a good choice. Here is an example where 
     we might not want to break before each 'if':

        ($Locale, @Locale) = ($English, @English) if (@English > @Locale);
        ($Locale, @Locale) = ($German,  @German)  if (@German > @Locale);
        ($Locale, @Locale) = ($French,  @French)  if (@French > @Locale);
        ($Locale, @Locale) = ($Spanish, @Spanish) if (@Spanish > @Locale);

     -Added wildcard file expansion for systems with shells which lack this.
     Now 'perltidy *.pl' should work under MSDOS/Windows.  Thanks to Hugh Myers 
     for suggesting this.  This uses builtin glob() for now; I may change that.

     -Added new flag -sbl which, if specified, overrides the value of -bl
     for opening sub braces.  This allows formatting of this type:

     perltidy -sbl 

     sub foo
     {
        if (!defined($_[0])) {
            print("Hello, World\n");
        }
        else {
            print($_[0], "\n");
        }
     }
     Requested by Don Alexander.

     -Fixed minor parsing error which prevented a space after a $$ variable
     (pid) in some cases.  Thanks to Michael Cartmell for noting this.
     For example, 
       old: $$< 700 
       new: $$ < 700

     -Improved line break choices 'and' and 'or' to display logic better.
     For example:

        OLD:
            exists $self->{'build_dir'} and push @e,
              "Unwrapped into directory $self->{'build_dir'}";

        NEW:
            exists $self->{'build_dir'}
              and push @e, "Unwrapped into directory $self->{'build_dir'}";

     -Fixed error of multiple use of abbreviatioin '-dsc'.  -dsc remains 
     abbreviation for delete-side-comments; -dsm is new abbreviation for 
     delete-semicolons.

     -Corrected and updated 'usage' help routine.  Thanks to Slaven Rezic for 
     noting an error.

     -The default for Windows is, for now, not to do a 'perl -c' syntax
     check (but -syn will activate it).  This is because of problems with
     command.com.  James Freeman sent me a patch which tries to get around
     the problems, and it works in many cases, but testing revealed several
     issues that still need to be resolved.  So for now, the default is no
     syntax check for Windows.

     -I added a -T flag when doing perl -c syntax check.
     This is because I test it on a large number of scripts from sources
     unknown, and who knows what might be hidden in initialization blocks?
     Also, deactivated the syntax check if perltidy is run as root.  As a
     benign example, running the previous version of perltidy on the
     following file would cause it to disappear:

            BEGIN{
                    print "Bye, bye baby!\n";
                    unlink $0;
            }
        
     The new version will not let that happen.

     -I am contemplating (but have not yet implemented) making '-lp' the
     default indentation, because it is stable now and may be closer to how
     perl is commonly formatted.  This could be in the next release.  The
     reason that '-lp' was not the original default is that the coding for
     it was complex and not ready for the initial release of perltidy.  If
     anyone has any strong feelings about this, I'd like to hear.  The
     current default could always be recovered with the '-nlp' flag.  

  2001 09 03

     -html updates:
         - sub definition names are now specially colored, red by default.  
           The letter 'm' is used to identify them.
         - keyword 'sub' now has color of other keywords.
         - restored html keyword color to __END__ and __DATA__, which was 
           accidentally removed in the previous version.

     -A new -se (--standard-error-output) flag has been implemented and
     documented which causes all errors to be written to standard output
     instead of a .ERR file.

     -A new -w (--warning-output) flag has been implemented and documented
      which causes perltidy to output certain non-critical messages to the
      error output file, .ERR.  These include complaints about pod usage,
      for example.  The default is to not include these.

      NOTE: This replaces an undocumented -w=0 or --warning-level flag
      which was tentatively introduced in the previous version to avoid some
      unwanted messages.  The new default is the same as the old -w=0, so
      that is no longer needed. 

      -Improved syntax checking and corrected tokenization of functions such
      as rand, srand, sqrt, ...  These can accept either an operator or a term
      to their right.  This has been corrected.
 
     -Corrected tokenization of semicolon: testing of the previous update showed 
     that the semicolon in the following statement was being mis-tokenized.  That
     did no harm, other than adding an extra blank space, but has been corrected.

              for (sort {strcoll($a,$b);} keys %investments) {
                 ...
              }

     -New syntax check: after wasting 5 minutes trying to resolve a syntax
      error in which I had an extra terminal ';' in a complex for (;;) statement, 
      I spent a few more minutes adding a check for this in perltidy so it won't
      happen again.

     -The behavior of --break-before-subs (-bbs) and --break-before-blocks
     (-bbb) has been modified.  Also, a new control parameter,
     --long-block-line-count=n (-lbl=n) has been introduced to give more
     control on -bbb.  This was previously a hardwired value.  The reason
     for the change is to reduce the number of unwanted blank lines that
     perltidy introduces, and make it less erratic.  It's annoying to remove
     an unwanted blank line and have perltidy put it back.  The goal is to
     be able to sprinkle a few blank lines in that dense script you
     inherited from Bubba.  I did a lot of experimenting with different
     schemes for introducing blank lines before and after code blocks, and
     decided that there is no really good way to do it.  But I think the new
     scheme is an improvement.  You can always deactivate this with -nbbb.
     I've been meaning to work on this; thanks to Erik Thaysen for bringing
     it to my attention.

     -The .LOG file is seldom needed, and I get tired of deleting them, so
      they will now only be automatically saved if perltidy thinks that it
      made an error, which is almost never.  You can still force the logfile
      to be saved with -log or -g.

     -Improved method for computing number of columns in a table.  The old
     method always tried for an even number.  The new method allows odd
     numbers when it is obvious that a list is not a hash initialization
     list.

       old: my (
                 $name,       $xsargs, $parobjs, $optypes,
                 $hasp2child, $pmcode, $hdrcode, $inplacecode,
                 $globalnew,  $callcopy
              )
              = @_;

       new: my (
                 $name,   $xsargs,  $parobjs,     $optypes,   $hasp2child,
                 $pmcode, $hdrcode, $inplacecode, $globalnew, $callcopy
              )
              = @_;

     -I fiddled with the list threshold adjustment, and some small lists
     look better now.  Here is the change for one of the lists in test file
     'sparse.t':
     old:
       %units =
         ("in", "in", "pt", "pt", "pc", "pi", "mm", "mm", "cm", "cm", "\\hsize", "%",
           "\\vsize", "%", "\\textwidth", "%", "\\textheight", "%");

     new:
       %units = (
                  "in",      "in", "pt",          "pt", "pc",           "pi",
                  "mm",      "mm", "cm",          "cm", "\\hsize",      "%",
                  "\\vsize", "%",  "\\textwidth", "%",  "\\textheight", "%"
                  );

     -Improved -lp formatting at '=' sign.  A break was always being added after
     the '=' sign in a statement such as this, (to be sure there was enough room
     for the parameters):

     old: my $fee =
            CalcReserveFee(
                            $env,          $borrnum,
                            $biblionumber, $constraint,
                            $bibitems
                            );
 
     The updated version doesn't do this unless the space is really needed:

     new: my $fee = CalcReserveFee(
                                   $env,          $borrnum,
                                   $biblionumber, $constraint,
                                   $bibitems
                                   );

     -I updated the tokenizer to allow $#+ and $#-, which seem to be new to
     Perl 5.6.  Some experimenting with a recent version of Perl indicated
     that it allows these non-alphanumeric '$#' array maximum index
     varaibles: $#: $#- $#+ so I updated the parser accordingly.  Only $#:
     seems to be valid in older versions of Perl.

     -Fixed a rare formatting problem with -lp (and -gnu) which caused
     excessive indentation.

     -Many additional syntax checks have been added.

     -Revised method for testing here-doc target strings; the following
     was causing trouble with a regex test because of the '*' characters:
      print <<"*EOF*";
      bla bla
      *EOF*
     Perl seems to allow almost anything to be a here doc target, so an
     exact string comparison is now used.

     -Made update to allow underscores in binary numbers, like '0b1100_0000'.

     -Corrected problem with scanning certain module names; a blank space was 
     being inserted after 'warnings' in the following:
        use warnings::register;
     The problem was that warnings (and a couple of other key modules) were 
     being tokenized as keywords.  They should have just been identifiers.

     -Corrected tokenization of indirect objects after sort, system, and exec,
     after testing produced an incorrect error message for the following
     line of code:
        print sort $sortsubref @list;

     -Corrected minor problem where a line after a format had unwanted
     extra continuation indentation.  

     -Delete-block-comments (and -dac) now retain any leading hash-bang line

     -Update for -lp (and -gnu) to not align the leading '=' of a list
     with a previous '=', since this interferes with alignment of parameters.

      old:  my $hireDay = new Date;
            my $self    = {
                         firstName => undef,
                         lastName  => undef,
                         hireDay   => $hireDay
                         };
    
      new:  my $hireDay = new Date;
            my $self = {
                         firstName => undef,
                         lastName  => undef,
                         hireDay   => $hireDay
                         };

     -Modifications made to display tables more compactly when possible,
      without adding lines. For example,
      old:
                    '1', "I", '2', "II", '3', "III", '4', "IV",
                    '5', "V", '6', "VI", '7', "VII", '8', "VIII",
                    '9', "IX"
      new:
                    '1', "I",   '2', "II",   '3', "III",
                    '4', "IV",  '5', "V",    '6', "VI",
                    '7', "VII", '8', "VIII", '9', "IX"

     -Corrected minor bug in which -pt=2 did not keep the right paren tight
     around a '++' or '--' token, like this:

                for ($i = 0 ; $i < length $key ; $i++ )

     The formatting for this should be, and now is: 

                for ($i = 0 ; $i < length $key ; $i++)

     Thanks to Erik Thaysen for noting this.

     -Discovered a new bug involving here-docs during testing!  See BUGS.html.  

     -Finally fixed parsing of subroutine attributes (A Perl 5.6 feature).
     However, the attributes and prototypes must still be on the same line
     as the sub name.

  2001 07 31

     -Corrected minor, uncommon bug found during routine testing, in which a
     blank got inserted between a function name and its opening paren after
     a file test operator, but only in the case that the function had not
     been previously seen.  Perl uses the existance (or lack thereof) of 
     the blank to guess if it is a function call.  That is,
        if (-l pid_filename()) {
     became
        if (-l pid_filename ()) {
     which is a syntax error if pid_filename has not been seen by perl.

     -If the AutoLoader module is used, perltidy will continue formatting
     code after seeing an __END__ line.  Use -nlal to deactivate this feature.  
     Likewise, if the SelfLoader module is used, perltidy will continue 
     formatting code after seeing a __DATA__ line.  Use -nlsl to
     deactivate this feature.  Thanks to Slaven Rezic for this suggestion.

     -pod text after __END__ and __DATA__ is now identified by perltidy
     so that -dp works correctly.  Thanks to Slaven Rezic for this suggestion.

     -The first $VERSION line which might be eval'd by MakeMaker
     is now passed through unchanged.  Use -npvl to deactivate this feature.
     Thanks to Manfred Winter for this suggestion.

     -Improved indentation of nested parenthesized expressions.  Tests have
     given favorable results.  Thanks to Wolfgang Weisselberg for helpful
     examples.

     -Fixed a very rare problem in which an unwanted semicolon was inserted
     due to misidentification of anonymous hash reference curly as a code
     block curly.  (No instances of this have been reported; I discovered it
     during testing).  A workaround for older versions of perltidy is to use
     -nasc.

     -Added -icb (-indent-closing-brace) parameter to indent a brace which
     terminates a code block to the same level as the previous line.
     Suggested by Andrew Cutler.  For example, 

            if ($task) {
                yyy();
                }    # -icb
            else {
                zzz();
                }

     -Rewrote error message triggered by an unknown bareword in a print or
     printf filehandle position, and added flag -w=0 to prevent issuing this
     error message.  Suggested by Byron Jones.

     -Added modification to align a one-line 'if' block with similar
     following 'elsif' one-line blocks, like this:
          if    ( $something eq "simple" )  { &handle_simple }
          elsif ( $something eq "hard" )    { &handle_hard }
     (Suggested by  Wolfgang Weisselberg).

  2001 07 02

     -Eliminated all constants with leading underscores because perl 5.005_03
     does not support that.  For example, _SPACES changed to XX_SPACES.
     Thanks to kromJx for this update.

  2001 07 01

     -the directory of test files has been moved to a separate distribution
     file because it is getting large but is of little interest to most users.
     For the current distribution:
       perltidy-20010701.tgz        contains the source and docs for perltidy
       perltidy-20010701-test.tgz   contains the test files

     -fixed bug where temporary file perltidy.TMPI was not being deleted 
     when input was from stdin.

     -adjusted line break logic to not break after closing brace of an
     eval block (suggested by Boris Zentner).

     -added flag -gnu (--gnu-style) to give an approximation to the GNU
     style as sometimes applied to perl.  The programming style in GNU
     'automake' was used as a guide in setting the parameters; these
     parameters will probably be adjusted over time.

     -an empty code block now has one space for emphasis:
       if ( $cmd eq "bg_untested" ) {}    # old
       if ( $cmd eq "bg_untested" ) { }   # new
     If this bothers anyone, we could create a parameter.

     -the -bt (--brace-tightness) parameter has been split into two
     parameters to give more control. -bt now applies only to non-BLOCK
     braces, while a new parameter -bbt (block-brace-tightness) applies to
     curly braces which contain code BLOCKS. The default value is -bbt=0.

     -added flag -icp (--indent-closing-paren) which leaves a statment
     termination of the form );, };, or ]; indented with the same
     indentation as the previous line.  For example,

        @month_of_year = (          # default, or -nicp
            'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct',
            'Nov', 'Dec'
        );

        @month_of_year = (          # -icp
            'Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct',
            'Nov', 'Dec'
            );

     -Vertical alignment updated to synchronize with tokens &&, ||,
     and, or, if, unless.  Allowable space before forcing
     resynchronization has been increased.  (Suggested by  Wolfgang
     Weisselberg).

     -html corrected to use -nohtml-bold-xxxxxxx or -nhbx to negate bold,
     and likewise -nohtml-italic-xxxxxxx or -nhbi to negate italic.  There
     was no way to negate these previously.  html documentation updated and
     corrected.  (Suggested by  Wolfgang Weisselberg).

     -Some modifications have been made which improve the -lp formatting in
     a few cases.

     -Perltidy now retains or creates a blank line after an =cut to keep
     podchecker happy (Suggested by Manfred H. Winter).  This appears to be
     a glitch in podchecker, but it was annoying.

  2001 06 17

     -Added -bli flag to give continuation indentation to braces, like this

            if ($bli_flag)
              {
                extra_indentation();
              }

     -Corrected an error with the tab (-t) option which caused the last line
     of a multi-line quote to receive a leading tab.  This error was in
     version 2001 06 08  but not 2001 04 06.  If you formatted a script
     with -t with this version, please check it by running once with the
     -chk flag and perltidy will scan for this possible error.

     -Corrected an invalid pattern (\R should have been just R), changed
     $^W =1 to BEGIN {$^W=1} to use warnings in compile phase, and corrected
     several unnecessary 'my' declarations. Many thanks to Wolfgang Weisselberg,
     2001-06-12, for catching these errors.
 
     -A '-bar' flag has been added to require braces to always be on the
     right, even for multi-line if and foreach statements.  For example,
     the default formatting of a long if statement would be:

            if ($bigwasteofspace1 && $bigwasteofspace2
              || $bigwasteofspace3 && $bigwasteofspace4)
            {
                bigwastoftime();
            }

     With -bar, the formatting is:

            if ($bigwasteofspace1 && $bigwasteofspace2
              || $bigwasteofspace3 && $bigwasteofspace4) {
                bigwastoftime();
            }
     Suggested by Eli Fidler 2001-06-11.

     -Uploaded perltidy to sourceforge cvs 2001-06-10.

     -An '-lp' flag (--line-up-parentheses) has been added which causes lists
     to be indented with extra indentation in the manner sometimes
     associated with emacs or the GNU suggestions.  Thanks to Ian Stuart for
     this suggestion and for extensive help in testing it. 

     -Subroutine call parameter lists are now formatted as other lists.
     This should improve formatting of tables being passed via subroutine
     calls.  This will also cause full indentation ('-i=n, default n= 4) of
     continued parameter list lines rather than just the number of spaces
     given with -ci=n, default n=2.
 
     -Added support for hanging side comments.  Perltidy identifies a hanging
     side comment as a comment immediately following a line with a side
     comment or another hanging side comment.  This should work in most
     cases.  It can be deactivated with --no-hanging-side-comments (-nhsc).
     The manual has been updated to discuss this.  Suggested by Brad
     Eisenberg some time ago, and finally implemented.

  2001 06 08

     -fixed problem with parsing command parameters containing quoted
     strings in .perltidyrc files. (Reported by Roger Espel Llima 2001-06-07).

     -added two command line flags, --want-break-after and 
     --want-break-before, which allow changing whether perltidy
     breaks lines before or after any operators.  Please see the revised 
     man pages for details.

     -added system-wide configuration file capability.
     If perltidy does not find a .perltidyrc command line file in
     the current directory, nor in the home directory, it now looks
     for '/usr/local/etc/perltidyrc' and then for '/etc/perltidyrc'.
     (Suggested by Roger Espel Llima 2001-05-31).

     -fixed problem in which spaces were trimmed from lines of a multi-line
     quote. (Reported by Roger Espel Llima 2001-05-30).  This is an 
     uncommon situation, but serious, because it could conceivably change
     the proper function of a script.

     -fixed problem in which a semicolon was incorrectly added within 
     an anonymous hash.  (Reported by A.C. Yardley, 2001-5-23).
     (You would know if this happened, because perl would give a syntax
     error for the resulting script).

     -fixed problem in which an incorrect error message was produced
      after a version number on a 'use' line, like this ( Reported 
      by Andres Kroonmaa, 2001-5-14):

                  use CGI 2.42 qw(fatalsToBrowser);

      Other than the extraneous error message, this bug was harmless.

  2001 04 06

     -fixed serious bug in which the last line of some multi-line quotes or
      patterns was given continuation indentation spaces.  This may make
      a pattern incorrect unless it uses the /x modifier.  To find
      instances of this error in scripts which have been formatted with
      earlier versions of perltidy, run with the -chk flag, which has
      been added for this purpose (SLH, 2001-04-05).

      ** So, please check previously formatted scripts by running with -chk
      at least once **

     -continuation indentation has been reprogrammed to be hierarchical, 
      which improves deeply nested structures.

     -fixed problem with undefined value in list formatting (reported by Michael
      Langner 2001-04-05)

     -Switched to graphical display of nesting in .LOG files.  If an
      old format string was "(1 [0 {2", the new string is "{{(".  This
      is easier to read and also shows the order of nesting.

     -added outdenting of cuddled paren structures, like  ")->pack(".

     -added line break and outdenting of ')->' so that instead of

            $mw->Label(
              -text   => "perltidy",
              -relief => 'ridge')->pack;
 
      the current default is:

            $mw->Label(
              -text   => "perltidy",
              -relief => 'ridge'
            )->pack;

      (requested by Michael Langner 2001-03-31; in the future this could 
      be controlled by a command-line parameter).

     -revised list indentation logic, so that lists following an assignment
      operator get one full indentation level, rather than just continuation 
      indentation.  Also corrected some minor glitches in the continuation 
      indentation logic. 

     -Fixed problem with unwanted continuation indentation after a blank line 
     (reported by Erik Thaysen 2001-03-28):

     -minor update to avoid stranding a single '(' on one line

  2001 03 28:

     -corrected serious error tokenizing filehandles, in which a sub call 
     after a print or printf, like this:
        print usage() and exit;
     became this:
        print usage () and exit;
     Unfortunately, this converts 'usage' to a filehandle.  To fix this, rerun
     perltidy; it will look for this situation and issue a warning. 

     -fixed another cuddled-else formatting bug (Reported by Craig Bourne)

     -added several diagnostic --dump routines
 
     -added token-level whitespace controls (suggested by Hans Ecke)

  2001 03 23:

     -added support for special variables of the form ${^WANT_BITS}

     -space added between scalar and left paren in 'for' and 'foreach' loops,
      (suggestion by Michael Cartmell):

        for $i( 1 .. 20 )   # old
        for $i ( 1 .. 20 )   # new

     -html now outputs cascading style sheets (thanks to suggestion from
      Hans Ecke)

     -flags -o and -st now work with -html

     -added missing -html documentation for comments (noted by Alex Izvorski)

     -support for VMS added (thanks to Michael Cartmell for code patches and 
       testing)

     -v-strings implemented (noted by Hans Ecke and Michael Cartmell; extensive
       testing by Michael Cartmell)

     -fixed problem where operand may be empty at line 3970 
      (\b should be just b in lines 3970, 3973) (Thanks to Erik Thaysen, 
      Keith Marshall for bug reports)

     -fixed -ce bug (cuddled else), where lines like '} else {' were indented
      (Thanks to Shawn Stepper and Rick Measham for reporting this)

  2001 03 04:

     -fixed undefined value in line 153 (only worked with -I set)
     (Thanks to Mike Stok, Phantom of the Opcodes, Ian Ehrenwald, and others)

     -fixed undefined value in line 1069 (filehandle problem with perl versions <
     5.6) (Thanks to Yuri Leikind, Mike Stok, Michael Holve, Jeff Kolber)

  2001 03 03:

     -Initial announcement at freshmeat.net; started Change Log
     (Unfortunately this version was DOA, but it was fixed the next day)
