From 192ce7a238af9021b0fd6dd571f22409af81ebaf Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Sun, 4 Jul 2010 15:00:51 -0400 Subject: remove unnecessary and troublesome filter calls This better defines what the filter hook is passed, to only be the raw, complete text of a page. Not some snippet, or data read in from an unrelated template. Several plugins that filtered text that originates from an (already filtered) page were modified not to do that. Note that this was not done very consistently before; other plugins that receive text from a page called preprocess on it w/o first calling filter. The template plugin gets text from elsewhere, and was also changed not to filter it. That leads to one known regression -- the embed plugin cannot be used to embed stuff in templates now. But that plugin is deprecated anyway. Later we may want to increase the coverage of what is filtered. Perhaps a good goal would be to allow writing a filter plugin that filters out unwanted words, from any input. We're not there yet; not only does the template plugin load unfiltered text from its templates now, but so can the table plugin, and other plugins that use templates (like inline!). I think we can cross that bridge when we come to it. If I wanted such a censoring plugin, I'd probably make it use a sanitize hook instead, for the better coverage. For now I am concentrating on the needs of the two non-deprecated users of filter. This should fix bugs/po_vs_templates, and it probably fixes an obscure bug around txt's use of filter for robots.txt. --- doc/plugins/write.mdwn | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'doc') diff --git a/doc/plugins/write.mdwn b/doc/plugins/write.mdwn index bb8012342..2e3902388 100644 --- a/doc/plugins/write.mdwn +++ b/doc/plugins/write.mdwn @@ -198,8 +198,8 @@ value is ignored. hook(type => "filter", id => "foo", call => \&filter); -Runs on the raw source of a page, before anything else touches it, and can -make arbitrary changes.
