- The --extrude option can produce code with syntax errors
+ The --extrude and --mangle options can produce code with syntax errors
The --extrude tries to put as many newlines in the formatted code as
- possible. This option is very useful for testing perltidy but not for
- actual formatting. Occasionally it will produce code which Perl
- considers to have a syntax error. These problems usually involve code
- where Perl is having to guess the tokenization based on whitespace.
- Since the --extrude option is typically only used for testing perltidy,
- this type of error should not normally occur in practice.
+ possible. The --mangle tries to remove as many newlines as possible.
+ These options are very useful for stress testing perltidy (and Perl) but
+ not so much for normal formatting. Occasionally they will produce code
+ which Perl considers to have a syntax error. These problems often
+ involve code where Perl is having to guess the tokenization based on
+ whitespace. The given/when and switch/case statements are also
+ particularly vulnerable to unusual line breaks and whitespace. This type
+ of error should not normally occur in practice, but if it does it should
+ be easy to fix the problem by rerunning perltidy with more normal
+ parameters or by manually changing whitespace or newlines.
+
+ The Pod:Html module has some bugs
+ For the most part Pod::Html works very well and is very convenient
+ because it part of the standard Perl distribution. But for example the
+ following line
+
+ =item B<< <Deck> = Session->new_cflt_deck; >>
+
+ which uses double brackets to contain single brackets does not render
+ correctly.
+
+ Perltidy does not handle UTF-8 encoded files
+ Two iterations are sometimes needed
+ Usually the code produced by perltidy on the first pass does not change
+ if it is run again, but sometimes a second pass will produce some small
+ additional change. This mainly happens if a major style change is made,
+ particularly when perltidy is untangling complex ternary statements. Use
+ the iteration parameter -it=2 if it is important that the results be
+ unchanged on subsequent passes, but note that this doubles the run time.
