convert delicious tags from space-separated to comma-separated

bash_convert_delicious_tags.sh

# delicious decided (out of nowhere) to change its tag separator from whitespace to comma,
# but since it didn't update it's browser plugin, i ended up with messed up multi-word tags
# here's my quick solution to fix that mess :
#
# 1] export all your delicious tags to a html file e.g. delicious.html
# 2] execute the below awk script to the exported file


BEGIN{ FS = "=" }
{
	i = 1;
	while( i <= NF ) {
		if( $i ~ /TAGS/ ) {
			printf( "%s%s", $i, FS )

			n = split( $(i + 1), a, "\"" )
			
			# the second element of the split array should contain the tags
			gsub( " ", ",", a[ 2 ] )
			
			# print the comma separated tags
			printf( "\"%s\"", a[ 2 ] )
			
			# reconstruct the rest of split array along with the split character
			# do not add the split character after the last element of the array
			for( j = 3; j <= n; j++ ) {
				printf( "%s%s", a[ j ], ( j != n ) ? "\"" : "" )
			}

			# skip the next record since we have just processed it
			i++
		}
		else {
			# if it's the last field do not use FS
			printf( "%s%s", $i, ( i != NF ) ? FS : "" )
		}
		
		i++
	}

	printf( "%s", ORS )
