Re: Indented HEREDOC?

[LanX]

Since this thread was my top-hit in google (YMMV):

Intended Here Documents were introduced with 5.26.

Indented Here-documents

This adds a new modifier "~" to here-docs that tells the parser that it should look for /^\s*$DELIM\n/ as the closing delimiter.

These syntaxes are all supported:

<<~EOF;
<<~\EOF;
<<~'EOF';
<<~"EOF";
<<~`EOF`;
<<~ 'EOF';
<<~ "EOF";
<<~ `EOF`;

The "~" modifier will strip, from each line in the here-doc, the same whitespace that appears before the delimiter.

Newlines will be copied as-is, and lines that don't include the proper beginning whitespace will cause perl to croak.

For example:

if (1) {
  print <<~EOF;
    Hello there
    EOF
}

prints "Hello there\n" with no leading whitespace.

Probably my favourite improvement since // defined-or.
