Text::EscapeDelimiters Description

Escape delimiter characters within strings When joining strings with a delimiter (aka separator), you need to worry about escaping occurences of that delimiter in the values you are joining. When splitting on the delimiter, you need to respect the escape sequences so you don't split on escaped delimiters.Text::EscapeDelimiters is a Perl module that provides a solution to that problem allowing you to escape values before you join, split the values whilst respecting escaped delimiters, and finally unescape the data.Escaping is achieved by placing an escape sequence in front of delimiter characters. The default escape sequence is a backslash but you can change this.$obj = new Text::EscapeDelimiters(\%options) Valid options are: EscapeSequence One or more characters that will be used as an escape sequence in front of delimiter characters. If not supplied, defaults to a backslash. An undef or empty string of this key can be used to specify a null escape sequence.$escaped = $obj->escape($string, $delimiters) Escapes one or more delimiter characters in a string ($delimiters can be a scalar or an an arrayref)@list = $obj->split($escaped_and_joined, $delimiter) Splits an escaped string on a delimiter (respecting escaped delimiters)$regex = $obj->regex($delimiters) Creates a regular expression that will match delimiters (but not escaped delimiters). $delimiters can be a scalar or an an arrayref.$string = $obj->unescape($escaped) Inverse of escape()SYNOPSIS my $obj = new Text::EscapeDelimiters(); #Convert a list of lists into a string using tab and newline as field and record delimiters #Escape any delimiters occurring in the strings first my $stringified = join("\n", map { join("\t", map {$obj->escape($_, )} @$_) } @records); #Convert the string back, respecting the escapes @records = map { } $obj->split($stringified, "\n"); #Pick off the first 5 records my $delim_regex = $obj->regex("\n"); my @first_five; for(1..5) { $stringified =~ /(.*?)$delim_regex/g; push @first_five, ; } Requirements: · Perl
