OK, some of you may know about POST_CHOMP and PRE_CHOM and TRIM.
POST_CHOMP and PRE_CHOMP allow you to automatically remove newlines and
whitespace between text and directives, so if both are true (as they are in
Slash), this:
[% FOREACH user = userlist %]
[% user %]
[% END %]
will be rendered as:
[% FOREACH user = userlist %][% user %][% END %]
You can de-activate this with "+", so this:
[% FOREACH user = userlist %]
[%+ user +%]
[% END %]
Will get treated just like this:
[% FOREACH user = userlist %]
[% user %]
[% END %]
Similarly, there is TRIM. This removes leading and trailing whitespace
from the output of templates and BLOCKs. This is also on in Slash.
I mention this because the behavior of POST_CHOMP and PRE_CHOMP are such
that it only works on [ \t\n]. But most of our templates have had "\r" in
them, as well, so it was not working properly. I have added code to
Slash::Display::Provider to convert CRLF to LF before the template is
compiled, so you may now see some slight changes in the output of
templates, especially in regard to leading and trailing newlines.
This is a similar issue to the previous one; it makes me think that we
probably should NOT bother to do "s/\n/\015\012/g" on templates being saved
TO the database from files. But if we do, it is not a big deal, because
they'll just be stripped before they are compiled.
