How can I format boolean operators with perltidy?-CodePudding

To my knowledge, perltidy is extremely handy and helpful when it comes to code formatting. However, I haven't found a way to fine-tune perltidy. For example, I need the && and || formatted so that there are two spaces before and after them. Like this:

$some && $x > 7;

Can I do it? If so, how?

CodePudding user response：

perltidy does not have an option to add two spaces before and after operators.

Furthermore, if you manually add 2 spaces, then run perltidy, it will convert the 2 spaces to a single space by default. However, there are options for skipping selected lines of code.

It's easy enough to rig up your own tidy script with PPI that you can run after perltidy. Proof-of-concept:

use PPI;
my $doc = PPI::Document->new($ARGV[0]);
for my $op (@{$doc->find('PPI::Token::Operator')}) {
    if ($op eq '&&' || $op eq '||') {
        $op->{content} = " $op ";
    }
}
print $doc;

And if we run this script on itself, we get:

$ perl je8tidy.pl je8tidy.pl
use PPI;
my $doc = PPI::Document->new($ARGV[0]);
for my $op (@{$doc->find('PPI::Token::Operator')}) {
    if ($op eq '&&'  ||  $ops eq '||') {
        $op->{content} = " $op ";
    }
}
print $doc;

it did insert the extra spaces around the only '||' operator on line 4.
