1Perltidy open BUGS and LIMITATIONS 2 You can help perltidy evolve into a better program. If you think you 3 have hit a bug or weird behavior, or have a suggested improvement, 4 please send a note to perltidy at users.sourceforge.net. 5 6 This file only lists open bugs. For bugs which have been fixed, see the 7 ChangeLog. 8 9 The --extrude and --mangle options can produce code with syntax errors 10 The --extrude tries to put as many newlines in the formatted code as 11 possible. The --mangle tries to remove as many newlines as possible. 12 These options are very useful for stress testing perltidy (and Perl) but 13 not so much for normal formatting. Occasionally they will produce code 14 which Perl considers to have a syntax error. These problems often 15 involve code where Perl is having to guess the tokenization based on 16 whitespace. The given/when and switch/case statements are also 17 particularly vulnerable to unusual line breaks and whitespace. This type 18 of error should not normally occur in practice, but if it does it should 19 be easy to fix the problem by rerunning perltidy with more normal 20 parameters or by manually changing whitespace or newlines. 21 22 The Pod:Html module has some bugs 23 For the most part Pod::Html works very well and is very convenient 24 because it part of the standard Perl distribution. But for example the 25 following line 26 27 =item B<< <Deck> = Session->new_cflt_deck; >> 28 29 which uses double brackets to contain single brackets does not render 30 correctly. 31 32 Perltidy does not handle UTF-8 encoded files 33 Two iterations are sometimes needed 34 Usually the code produced by perltidy on the first pass does not change 35 if it is run again, but sometimes a second pass will produce some small 36 additional change. This mainly happens if a major style change is made, 37 particularly when perltidy is untangling complex ternary statements. Use 38 the iteration parameter -it=2 if it is important that the results be 39 unchanged on subsequent passes, but note that this doubles the run time. 40 41 Latest Bug and Wishlist at CPAN: 42 For the latest list of bugs and feature requests at CPAN see: 43 44 https://rt.cpan.org/Public/Dist/Display.html?Name=Perl-Tidy 45 46
