Hi folks,
The single longest-standing and most egregious lack of functionality in
Haml, as detailed in
http://nex-3.com/posts/75-haml-whitespace-handling-sucks-too, has
finally been fixed. It's now possible to get Haml *not* to insert
whitespace either around or within tags.
The syntax for this is angle brackets, > or <, placed at the end of a
tag (after the attributes but before = or / if you have them). You can
think of them as alligators, chomping on whitespace. > is chomping the
whitespace on the outside:
%blockquote
%p>
Foo
Bar
=>
<blockquote><p>
Foo
Bar
</p></blockquote>
And < is chomping the whitespace on the inside:
%blockquote
%p<
Foo
Bar
=>
<blockquote>
<p>Foo
Bar</p>
</blockquote>
These aren't the best examples, because they're not terribly useful. But
you can also do stuff like
%img
%img>
%img
=>
<img /><img /><img />
Or
%pre<
:preserve
Foo
Bar
Baz
=>
<pre>Foo
 Bar
 Baz
</pre>
You can use this right now by getting Haml from
git://github.com/nex3/haml.git and running "rake install" to install it
as a gem.
Many thanks to everyone who helped out with brainstorming how this
feature should work, including Evgeny Zislis and Sunny Ripert on my
blog, Nathan Sutton and Dustin Sallings on #haml on freenode, and many
people in various conversations on this mailing list.
