Perltidy Change Log
+ 2009 06 16
+ - Allow configuration file to be 'perltidy.ini' for Windows systems.
+ i.e. C:\Documents and Settings\User\perltidy.ini
+ and added documentation for setting configuation file under Windows in man
+ page. Thanks to Stuart Clark.
+
+ - Corrected problem of unwanted semicolons in hash ref within given/when code.
+ Thanks to Nelo Onyiah.
+
+ - added new flag -cscb or --closing-side-comments-balanced
+ When using closing-side-comments, and the closing-side-comment-maximum-text
+ limit is exceeded, then the comment text must be truncated. Previous
+ versions of perltidy terminate with three dots, and this can still be
+ achieved with -ncscb:
+
+ perltidy -csc -ncscb
+
+ } ## end foreach my $foo (sort { $b cmp $a ...
+
+ However this causes a problem with older editors which cannot recognize
+ comments or are not configured to doso because they cannot "bounce" around in
+ the text correctly. The B<-cscb> flag tries to help them by
+ appending appropriate terminal balancing structure:
+
+ perltidy -csc -cscb
+
+ } ## end foreach my $foo (sort { $b cmp $a ... })
+
+ Since there is much to be gained and little to be lost by doing this,
+ the default is B<-cscb>. Use B<-ncscb> if you do not want this.
+
+ Thanks to Daniel Becker for suggesting this option.
+
+ - After an isolated closing eval block the continuation indentation will be
+ removed so that the braces line up more like other blocks. Thanks to Yves Orton.

+
+ NEW:

+ #STUFF;
+ 1; # return true
+ } or do {
+ #handle error
+ };
+
+ -A new flag -asbl (or --opening-anonymous-sub-brace-on-new-line) has
+ been added to put the opening brace of anonymous sub's on a new line,
+ as in the following snippet:
+
+ my $code = sub
+ {
+ my $arg = shift;
+ return $arg->(@_);
+ };
+
+ This was not possible before because the -sbl flag only applies to named
+ subs. Thanks to Benjamin Krupp.
+
+ -Fix tokenization bug with the following snippet
+ print 'hi' if { x => 1, }->{x};
+ which resulted in a semicolon being added after the comma. The workaround
+ was to use -nasc, but this is no longer necessary. Thanks to Brian Duggan.
+
+ -Fixed problem in which an incorrect error message could be triggered
+ by the (unusual) combination of parameters -lp -i=0 -l=2 -ci=0 for
+ example. Thanks to Richard Jelinek.
+
+ -A new flag --keep-old-blank-lines=n has been added to
+ give more control over the treatment of old blank lines in
+ a script. The manual has been revised to discuss the new
+ flag and clarify the treatment of old blank lines. Thanks
+ to Oliver Schaefer.

if you do not want this, use -nola in your .perltidyrc file.

to introduce this problem when cutting and pasting. Perl does not
complain about it, but it can lead to disaster.
-Side comment alignment has been improved somewhat across frequent level
changes, as in short if/else blocks. Thanks to Wolfgang Weisselberg
for pointing out this problem. For example:
-

if ( ref $self ) { # Called as a method

-I am contemplating (but have not yet implemented) making '-lp' the
default indentation, because it is stable now and may be closer to how
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

continued parameter list lines rather than just the number of spaces
given with -ci=n, default n=2.
