Bracket Pair Colorization does not handle Perl punctuation variables #168110

@FractalBoy

Description

@FractalBoy

Type: Bug

Perl has a bunch of punctuation variables including $) and $(. You can find documentation on all of these variables in perlvar.

Bracket pair colorization does not seem to handle these well, resulting in it turning brackets red when there is actually a matching close bracket.

To reproduce:

  1. Turn on bracket pair colorization
  2. Create new perl file (test.pl, for example)
  3. Write the following code:
#!/usr/bin/perl
($));
  1. Run the code in perl - it runs with no syntax errors (though does nothing).
  2. VSCode reports the parentheses as not matching.

Here is another, more complex, example - in this case, VSCode colors all the curly brackets red instead of the parentheses:

#!/usr/bin/perl

sub test
{
    return;
}

test(
    sub {
        my $x = sub { scalar(getpwuid($>)), $) };
    }
);
