Re: Pretty Print (perltidy integration)

Actually there are three questions involved

A) how to do this in a backwards compatible way to still be able to see the unformatted code. (Much posted code is broken, we need a fallback)

B) if syntax highlighting should be added too

C) how to implement this into the process chain

Brainstorm:

A) The only chance I see is an additional displaytype, like this users could switch between raw and formated source

B) perltidy can also produce highlighted code, but startup is slow and would cause a lag

C) patching perltidy to run in a server mode might be a solution.

Alternatives?

FWIW: Actually no patch needed, this code from Perl::Tidy is very fast after initialization (which can take 1-2 secs) `use Perl::Tidy; # ... # run in a loop reading source and outputting dest my $error = Perl::Tidy::perltidy( argv => $argv, source => \$source_string, destination => \$dest_string, stderr => \$stderr_string, errorfile => \$errorfile_string, + );` [download] Indenting some lines on laptop took under 0.05 sec and own formatters for "special" html are easily implemented.

FWIW:

Actually no patch needed, this code from Perl::Tidy is very fast after initialization (which can take 1-2 secs)

use Perl::Tidy;
 
# ...
# run in a loop reading source and outputting dest
   my $error = Perl::Tidy::perltidy(
                                    argv        => $argv,
                                    source      => \$source_string,
                                    destination => \$dest_string,
                                    stderr      => \$stderr_string,
                                    errorfile   => \$errorfile_string,
+ 
                                   );
