Yes, if templates COULD handle it, that would be best. But the hard
linewraps need to be done in PHP scope, they cannot be achieved via CSS. If
you think they can, please provide the code how "hahahahahahahahaaaaaaaaaa"
would be split WITHOUT using a scrollbar. That would be most appreciated,
because I do not know about such a solution.

The problem is even if special markup is trimmed, it gets converted to
HTML, which would still be split. It's very hard to ensure that an opened
tag is always closed, because if I prepend "[B]" before a 200kb comment,
and at the end use "[/B]" I would have to emit the whole code to get the
ending string.

If the main reason is to preserve the layout i think handling of overflows
should be in the domain of the templates not in the domain of program
logic. We have the ability to do this with css which has none of the
unwanted sideeffects the current implementation has.

The only remaining problem then would be the handling of markup at the end
of strings, that still get cut. Maybe parsing special markup should occur
before trimming the strings?

Hi!

The main reason is, that the comment sidebar plugin needs to ensure that
lines are cut after X characters (using wordwrap() PHP function). We need
to force cutting, because otherwise the sidebar can be broken by user
comments like "hahaaaaaaaaaaaaaaaaaaaaahahaaaaaaaaaaaaaaaaaaaahahaha",
which is of course what we need to prevent in first instance.

Because of this cutting, it can happen that a [bbcode] instance is broken
in the middle, and because of that, the bbcode markup cannot be applied.

Some people prevent the wordwrapping bug by setting the wordwrap number to
"999999" and then using CSS and "overflow: hidden" as well as a "width"
property in the templates Stylesheet. So if you don't see a need in hard
linebreaks, you can use that method.

HTH,
Garvin

Hi Garvin,

before I reported the bug i took a short look into the relevant code, so
i'm aware that it is not as simple as it seems. I would have fixed it by
myself. The question i have is: what's the reason for cutting the strings.
I see no use in hard linebreaks. To me it seems they are causing trouble
but have no true benefit. It's not only BBCode that gets broken by it.
Normal text is sometimes also broken in the midst of a word.

best regards
Lars

Hi lbecker,

sadly BBCode truncating is not as trivial as it seems (read the mentioned
URLs in the original tracker item), so there hasn't been progress on this.

Actually, I don't think this can really be resolved. Whenever you cut
strings in a hard way to force linebreaks in the browser, you cannot be
sure to not truncate bbcode or HTML in the middle without really
performanse intensive parsing.

Are there any updates on this? I experience the same problems with BBCode
which are somewhat annoying since "BBCode" and "recent comments" both are
core plugins of s9y.
