Hello Porters.
Indented heredocs would be a wonderful feature to have, but I hear a
lot of people saying it's not possible.
I'm wondering why this is?
Attached is a *ROUGH* patch that adds new syntax to allow indented
heredocs, at least in this simple case:
if (1) {
print <<~EOF;
Lorem Something Or Other
EOF
}
(It also allows <<~'EOF', <<~"EOF").
Right now, it doesn't remove the beginning indentation of the indented
heredoc, but it could easily, following Perl 6's rules perhaps:
Lines with more indentation than the delimiter will appear indented
by however much extra space they use, and lines with less indentation
will be as indented as the delimiter, with a warning about the issue.
As I've implemented it, the closing delimiter must match:
/^\s+$delim\n/
So that $delim can exist anywhere in the text (excepting where it closes).
What am I missing? Can we do this?
Thanks for your time,
-- Matthew Horsfall (alh)
