Re: Pretty Print (perltidy integration)

[LanX]

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,
+ 
                                   );

Indenting some lines on laptop took under 0.05 sec and own formatters for "special" html are easily implemented.

(trying to implement a so called "asynchronous process" interface for emacs now)
