Unable to parse heredoc inside a block properly

[bpradeep20]

Config:

<main>
    PYTHON <<MYPYTHON
        def a():
            x = y
            return
    MYPYTHON
</main>

With python version of config parser I am getting parse error

But with perl version:

$VAR1 = {
          'main' => {
                      'PYTHON' => 'def a():
        x = y
        return'
                    }
        };

Can you please check?

The issue here is that closing MYPYTHON anchor is indented. I've modified the lexer to allow that (see commit 8a9f5b3).

But now I am curious how would you include MYPYTHON content into the heredoc block? There should be some sort of escaping, right?

[etingof]

Hmm, is it a good idea to allow whitespaces around the anchor? At least with bash, this is not allowed.

This is working with current version of code.

It does, but I feel like this may break things elsewhere. May be we should better make this behavior configurable.

[bpradeep20]

I agree. It would be great of we have some option to enable PERL heredoc and keep default as BASH here doc.

Hey, @sydneyli! Do you think this has been fixed lately?

[sydneyli]

The behavior in the original issue fixed, but extra whitespaces after the closing heredoc anchor seems to still break things.
Edit: It might be good to change the title of this issue to reflect the above?
