The rather short explanation of filter chaining in the documentation
seems to imply (to me, at least) that this is possible. However, I get
a syntax error that complains about the "|" after the first filter
(html_entity).
Either solution, a custom filter that encapsulates a few others, or the
ability to chain, would sure save me a lot of typing...
I don't use ttree so I don't know if the following is possible or not, but I'd
imagine so.
If you don't use a custom filter, then some other solutions might be to do:
[% result = BLOCK %]
A long block of raw text to be converted to HTML, wrapped, and indented...
[% END %]
[% result | html_entity | wrap(95) | indent("\t") %]
OR:
[% BLOCK myblock %]
A long block of raw text to be converted to HTML, wrapped, and indented...
[% END %]
[% PROCESS myblock | html_entity | wrap(95) | indent("\t") %]
OR:
You might even be able to use a wrapper. (You can keep reusing it too.)
[% BLOCK myfilters %]
[% content | html_entity | wrap(95) | indent("\t") %]
[% END %]
[% WRAPPER myfilters %]
A long block of raw text to be converted to HTML, wrapped, and indented...
[% END %]
Disclaimer: I have not tested any of these, but they sound like they should
work. At the very least they might give you some ideas.
