Hi Lux,
Here are two perl text filters.
Copy them to ~/Library/Application Support/BBEdit/Text Filters.
You can test them from menu Text > Apply Text Filter.
This one (tags_and_categories_to_list_pl.pl) is for your initial case (CSV
-> hyphenated item per line) :
#!/usr/bin/env perl
use v5.14;
use strict;
use warnings;
while(my $line = <>) {
if (my ($field, $items) = $line =~
/^(tags|categories):\s*(.+)\s*$/gi) {
my $yaml_items = $items =~ s/\s*,\s*/\n- /gr;
print "${field}:\n- ${yaml_items}\n";
} else {
print $line;
}
}
=for test
I got a huge number of posts from an old static blog. Inside the header
there's a "tags" line, made this way:
tags: Steve Jobs, Steve Throughton-Smith, T'Bone, Better to Be a Pirate
Than Join the Navy, Ben & Jerry, NBA75
The actual number of tags in the line can be any. Comma act as a
delimiter and, after that, any character can be used inside a tag, spaces
included.
categories: Education
=cut
This other one (tags_and_categories_to_array_pl.pl) if for your second case
(hyphenated item per line -> array):
#!/usr/bin/env perl
use v5.14;
use strict;
use warnings;
$/ = undef;
sub replace {
my $match = shift;
my @splitted = split /[[:blank:]]*\n[[:blank:]]*-[[:blank:]]/,
$match;
my $field = shift @splitted;
map { s/^\s+|\s+$//g; } @splitted;
my $joined = join ", ", @splitted;
return "${field} [${joined}]\n";
}
print <> =~
s/^((?:tags|categories)[[:blank:]]*:[[:blank:]]*\n[[:blank:]]*(?:-[^\n]+\n)+)/replace
$1/grimse;
=for test
title: "Più uguali degli altri"

HTH,
