## 2023 03 09
- No significant bugs have been found since the last release to CPAN.
Several minor issues have been fixed, and some new parameters have been
added, as follows:
- Added parameter --one-line-block-exclusion-list=s, or -olbxl=s, where
s is a list of block types which should not automatically be turned
into one-line blocks. This implements the issue raised in PR #111.
The list s may include any of the words 'sort map grep eval', or
it may be '*' to indicate all of these. So for example to prevent
multi-line 'eval' blocks from becoming one-line blocks, the command
would be -olbxl='eval'.
- For the -b (--backup-and-modify-in-place) option, the file timestamps
are changing (git #113, rt#145999). First, if there are no formatting
changes to an input file, it will keep its original modification time.
Second, any backup file will keep its original modification time. This
was previously true for --backup-method=move but not for the default
--backup-method=copy. The purpose of these changes is to avoid
triggering Makefile operations when there are no actual file changes.
If this causes a problem please open an issue for discussion on github.
- A change was made to the way line breaks are made at the '.'
operator when the user sets -wba='.' to requests breaks after a '.'
( this setting is not recommended because it can be hard to read ).
The goal of the change is to make switching from breaks before '.'s
to breaks after '.'s just move the dots from the end of
lines to the beginning of lines. For example:
# default and recommended (--want-break-before='.'):
$output_rules .=
( 'class'
. $dir
. '.stamp: $('
. $dir
. '_JAVA)' . "\n" . "\t"
. '$(CLASSPATH_ENV) $(JAVAC) -d $(JAVAROOT) '
. '$(JAVACFLAGS) $?' . "\n" . "\t"
. 'echo timestamp > class'
. $dir
. '.stamp'
. "\n" );
# perltidy --want-break-after='.'
$output_rules .=
( 'class' .
$dir .
'.stamp: $(' .
$dir .
'_JAVA)' . "\n" . "\t" .
'$(CLASSPATH_ENV) $(JAVAC) -d $(JAVAROOT) ' .
'$(JAVACFLAGS) $?' . "\n" . "\t" .
'echo timestamp > class' .
$dir .
'.stamp' .
"\n" );
For existing code formatted with -wba='.', this may cause some
changes in the formatting of code with long concatenation chains.
- Added option --use-feature=class, or -uf=class, for issue rt #145706.
This adds keywords 'class', 'method', 'field', and 'ADJUST' in support of
this feature which is being tested for future inclusion in Perl.
An effort has been made to avoid conflicts with past uses of these
words, especially 'method' and 'class'. The default setting
is --use-feature=class. If this causes a conflict, this option can
be turned off by entering -uf=' '.
In other words, perltidy should work for both old and new uses of
these keywords with the default settings, but this flag is available
if a conflict arises.
- Added option -bfvt=n, or --brace-follower-vertical-tightness=n,
for part of issue git #110. For n=2, this option looks for lines
which would otherwise be, by default,
}
or ..
and joins them into a single line
} or ..
where the or can be one of a number of logical operators or if unless.
The default is not to do this and can be indicated with n=1.
- Added option -cpb, or --cuddled-paren-brace, for issue git #110.
This option will cause perltidy to join two lines which
otherwise would be, by default,
)
{
into a single line
) {
- Some minor changes to existing formatted output may occur as a result
of fixing minor formatting issues with edge cases. This is especially
true for code which uses the -lp or -xlp styles.
- Added option -dbs, or --dump-block-summary, to dump summary
information about code blocks in a file to standard output.
The basic command is:
perltidy -dbs somefile.pl >blocks.csv
Instead of formatting ``somefile.pl``, this dumps the following
comma-separated items describing its blocks to the standard output:
filename - the name of the file
line - the line number of the opening brace of this block
line_count - the number of lines between opening and closing braces
code_lines - the number of lines excluding blanks, comments, and pod
type - the block type (sub, for, foreach, ...)
name - the block name if applicable (sub name, label, asub name)
depth - the nesting depth of the opening block brace
max_change - the change in depth to the most deeply nested code block
block_count - the total number of code blocks nested in this block
mccabe_count - the McCabe complexity measure of this code block
This can be useful for code restructuring. The man page for perltidy
has more information and describes controls for selecting block types.
- This version was stress-tested for over 100 cpu hours with random
input parameters. No failures to converge, internal fault checks,
undefined variable references or other irregularities were seen.
- This version runs a few percent faster than the previous release on
large files due to optimizations made with the help of Devel::NYTProf.
