Re: need <-[x]> help

Hi Todd,

I tried to match a single string to begin with:

my $x = '"7" ab"';
$x ~~ s:g/ (.) \"  /inches($0)/;
say $x;

# "inches(7) ab"

you want a negative lookahead assertion, which are described (with an
example) at https://docs.perl6.org/language/regexes#Lookahead_Assertions

Hi All,

What I am trying to do is to replace a quote `"`
with `inches`, but NOT when the quote is followed
by a comma `,`.

In other words, ignore `",`

I am not having too good a time with it.  What am I
doing wrong?

$ perl6 -e 'my $x=qw["44","7" ab","","999"]; say 
"$x";$x~~s:g/\"(.)<-[,]>/ inches($0)/; say "$x";'


"44","7" ab","","999"
inches(4)inches(,)7inches( )binches(,)inches(,)999"

desired output:
"44","7 inches ab","","999"

Many thanks,
-T

next step, ignoring the quote at the end of the line.
