BLOGC-TOCTREE(7) blogc Manual BLOGC-TOCTREE(7)

NAME

blogc-toctree - blogc´s "table of contents" tree support

DESCRIPTION

blogc(1) generates a "table of contents" tree for every source file, out of its content headers, that is available for usage as a {{ TOCTREE }} template variable. The tree is composed by lists of links for the headers, and is usually placed right before the content, as an index.

USAGE

For a source file with the following content:

TITLE: Some Title
-----------------
# Header 1
Some content.
## Header 2
More content.
### Header 3
Content.

A template block with the following content:

{% block entry %}
{{ TOCTREE }}
{% endblock %}

Would generate output similar to this:

<ul>

<li><a href="#header-1">Header 1</a></li>
<ul>
<li><a href="#header-2">Header 2</a></li>
<ul>
<li><a href="#header-3">Header 3</a></li>
</ul>
</ul> </ul>

The depth of the tree can be controlled using the TOCTREE_MAXDEPTH variable, that may be defined globally (see blogc(1)) or for each source file (see blogc-source(7)). Setting this variable to 0 disables the generator. Setting this variable to a positive number will limit the number of tree levels to such value. The default value is -1, which means no maximum depth.

Please note that the depth is evaluated from the lower header level available in the content. This means that if a source file only have level 2 and level 3 headers, and TOCTREE_MAXDEPTH=1, only headers with level 2 are included in the "table of contents" tree.

For a source file with the following content:

TITLE: Some Title
TOCTREE_MAXDEPTH: 1
-----------------
## Header 2
Some content
### Header 3
More content

With the same template presented before, would generate output similar to this:

<ul>

<li><a href="#header-2">Header 2</a></li> </ul>
