Javascript resources should be presented to browsers after CSS, and
"after the fold" (ATF) according to the best practices:
https://developers.google.com/speed/docs/insights/mobile#PutStylesBeforeScripts
This change allows the browser to download Javascript files in
parallel, by including Javascript on the *closing* </body> tag instead
of the opening tag.
We also improve the regex to tolerate spaces before the body tag, as
some templates have (proper) indentation for the tag.
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.
* Add an underlay for javascript, and add ikiwiki.js containing some utility
code.
* toggle: Stop embedding the full toggle code on each page using it, and
move it to toggle.js in the javascript underlay.
* toc: Revert change in 2.45 that made it run at sanitize time. This breaks
use of toc in a sidebar.
* Call format hooks when generating page previews, thus fixing toc display
there, as well as fixing inlins to again display in page previews, since
it's started using format hooks. This also allows several other things,
like embed, that use format hooks, to work during page preview time.
* Format hooks should not rely on getting an entire html document, as they
will only get the body during page preview.
* toggle: Deal with preview mode when adding javascript.
for extended pagespecs. The old calling convention will still work for
back-compat for now.
* The calling convention for functions in the IkiWiki::PageSpec namespace
has changed so they are passed named parameters.
* Plugin interface version increased to 2.00 since I don't anticipate any
more interface changes before 2.0.
* Introduce the nicebundle. This is a kind of plugin, that just enables
many other plugins. It's an easy way to boost ikiwiki from its default,
basic wiki, to a full-featured wiki, without manually picking the right
set of plugins. New plugins will be added to the nicebundle from time to
time.
