Newline not preserved after tag when using line whitespace trimming

[ericmorand]

Consider the following template:

{% do 1 + 2 ~%}
    foo

When rendered, we get:

    foo

https://twigfiddle.com/oxixzf

But according to the documentation:

Line whitespace trimming via the ~ modifier: Removes all whitespace (excluding newlines). Using this modifier on the right disables the default removal of the first newline inherited from PHP.

Shouldn't the newline after the do tag be preserved?

The compiled template (which can be displayed on twigfiddle) shows that it is rendering a newline char. So this might actually be an issue of Twigfiddle itself not support an output starting with a newline char, or something like that.

See https://twigfiddle.com/0nw355 for a fiddle having the same issue in the rendered output, while there is definitely a newline char being rendered.

Oh, thanks. I should have checked with TwigPHP itself.

Well, twigfiddle is a nice tool, but it might have bugs too. I reported it there

[ericmorand]

Yes, thanks for that. The "Show raw result" button is quite confusing to me. Very nice tool though but I'll double-check with my local TwigPHP environment in the future.

Hi there,

Sorry about that guys, will fix the tool soon.
