MojoMojo::Formatter::TOC \- generate table of contents
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This formatter will replace \f(CW\*(C`{{toc}}\*(C'\fR with a table of contents, using
HTML::GenToc. If you don't want an element to be included in the \s-1TOC,\s0
make it have \f(CW\*(C`class="notoc"\*(C'\fR
.SH "METHODS"
.IX Header "METHODS"
.SS "format_content_order"
.IX Subsection "format_content_order"
The \s-1TOC\s0 formatter expects \s-1HTML\s0 input so it needs to run after the main
formatter. Since comment-type formatters (order 91) could add a heading
for the comment section, the \s-1TOC\s0 formatter will run with a priority of 95.
.SS "format_content"
.IX Subsection "format_content"
Calls the formatter. Takes a ref to the content as well as the context object.
The syntax for the \s-1TOC\s0 plugin invocation is:
.PP
.Vb 3
\&  {{toc M\- }}     # start from Header level M
\&  {{toc \-N }}     # stop at Header level N
\&  {{toc M\-N }}    # process only header levels M..N
.Ve
.PP
where M is the minimum heading level to include in the \s-1TOC,\s0 and N is the
maximum level (depth). For example, suppose you only have one H1 on the page
so it doesn't make sense to add it to the \s-1TOC\s0; also, assume you and don't want
to include any headers smaller than H3. The {{toc}} markup to achieve that would be:
.PP
.Vb 1
\&  {{toc 2\-3}}
.Ve
.PP
Defaults to 1\-6.
.SS "SEO-friendly anchors"
.IX Subsection "SEO-friendly anchors"
Anchors should be generated with \s-1SEO\- \s0(and human\-) friendly names, i.e. out of the entire
token text, instead of being numeric or reduced to the first word(s) of the token.
In the spirit of http://seo2.0.onreact.com/top\-10\-fatal\-url\-design\-mistakes, compare:
.PP
.Vb 3
\&  http://beachfashion.com/photos/Pamela_Anderson#In_red_swimsuit_in_Baywatch
\&    vs.
\&  http://beachfashion.com/photos/Pamela_Anderson#in
.Ve
.PP
\&\*(L"Which one speaks your language more, which one will you rather click?\*(R"
.PP
The anchor names generated are compliant with \s-1XHTML1.0\s0 Strict. Also, per the
\&\s-1HTML 4.01\s0 spec, anchor names should be restricted to \s-1ASCII\s0 characters and
anchors that differ only in case may not appear in the same document. In
particular, an anchor name may be defined only once in a document (logically,
because otherwise the user agent wouldn't know which #foo to scroll to).
This is currently a problem with HTML::Toc v1.11, which doesn't have
support for passing the already existing anchors to the \f(CW\*(C`templateAnchorName\*(C'\fR
sub.
