whitespace removal syntax not working with php-statements
Hi,
the php-renderer does not respect the whitespace-removal-settings of parent-nodes, which will introduce unwanted whitespaces.
Here's an example:
%a<>
- foreach(array(1,2,3) as $ndx)
%span<>
=$ndx
should render to something like
<a><span>1</span><span>2</span><span>3</span></a>
It looks not that easy to fix the underlying problem, so I replaced all write with raw in my fork. Is there an easy way to fix this?
Same thing in Haml/TWIG when using if/for/macros/etc.
White space removal is really useful when using inline or inline-block positioning for horizontal layouts, i.e. this is not just cosmetic. See: http://css-tricks.com/fighting-the-space-between-inline-block-elements/, stmh's issue above is the same thing.
Whitespace removal won't work for me at all.
This MtHaml:
%span.text-small><
(
= $no_reviews
)
produces this HTML:
<span class="text-small">(
16 )</span>
Please mark this a a bug.
PS Haml docs: http://haml.info/docs/yardoc/file.REFERENCE.html#whitespace_removal__and_
From your example, it works as documented: it removes whitespace just after <span class="text-small">, and just before </span>, but not in the content (which is what it's expected to do).
See the example from HAML/Ruby documentation:
%img
%pre><
foo
bar
%img
is compiled to:
<img /><pre>foo
bar</pre><img />
Note that you can make use of interpolations, for this use-case:
%span.text-small (#{$no_reviews})
(#{...} works like it works in Ruby, mostly like {$...} in PHP)
@arnaud-lb, i'm quoting the documentation:
>will remove all whitespace surrounding a tag, while<will remove all whitespace immediately within a tag.
Neither works for me. From my excerpt, you can only tell about the latter, but surrounding whitespace is also not removed.
Oh, i'm also inside a foreach, as the OP. Anyway, why is this not marked as a bug?
One difference, though, is that in HAML/Ruby, < also eats indentation, whereas in MtHaml it doesn't.

The only reason to use whitespace removal for me is the inline-block grid technique. Whitespace adds to row width, ruining the grid. If MtHaml can't properly remove indentation, then whitespace removal is not working and thus useless.
I hacked in some changes in my fork that enable me to remove whitespace using <> where I need to. It ruins pretty printing because it's not possible to determine the right thing to do in some cases (macros/conditionals output in first and last node? memory is getting fuzzy...).

I've tried the > and < whitespace removal outside any PHP statements, and it won't work properly:
-
>removes whitespace only after the element, while it should remove whitespace before and after the element. -
<removes whitespace only before the content of the element, while it should remove whitespace before, between and after the containing elements.
Putting this inside a in if (true) PHP statement makes it a bit worse. The < removes linebreaks but adds space characters.
@arnaud-lb, any progress on this one?
Bump, it would be nice to have this fixed.
Not being able to control the white-space causes major problems with text in HTML textarea form elements.
