[nikola-discuss] How to reference a metadata value in reStructuredText?
Hi all,
I'm sure I overlooked something basic - how can I output a metadata
variable from my document via reStructuredText?I've read extensively
about these values but cannot find how to use one in a post or file. None
of the tests below work to render the value assigned to the slug. Also,
are there any examples of more advanced .rst documents used with Nikola?
Maybe I can find some answers by example.
.. title: 1960s Macho Legends
.. slug: macho-legends
My slug is {$slug}
or is it ``slug``
or is it :slug:
our could it be {{% slug %}}
nfw it is {{% raw %}}{{% slug %}}{{% /raw %}}

Chris, the docs indicate that the value still needs to be resolved to be
passed to the template.
Suppose I create shortcodes/foo.tmpl as such:
This uses the bar variable: ${bar}
And my post contains this:
{{% foo bar=slug %}}
Then the output file will contain:
This uses the bar variable: slug
But I want to output the value of *slug*. In shell it would be the simple
difference of echo $slug vs echo slug.

Chris, thanks for the clue. I still have not escaped the room. Tried with
no avail:
{{% post.title %}}
{{% post.data(title) %}}
{{% post.data title %}}

Re: [nikola-discuss] How to reference a metadata value in reStructuredText?
Why does "title" work but not "slug"?
{{% template %}}
The title is: ${post.slug()}
{{% /template %}}
... rejected

Re: [nikola-discuss] How to reference a metadata value in reStructuredText?
What is the context for using* echo '${post.title()}' > shortcodes/foo.tmpl
*? This is not restructured text, it would be some sort of shell escape
that is recognized and executed during a build I suppose? I could not find
this documented. If embedded shell hooks are possible, perhaps I could
parse the slug value out of the header via awk in order to output it.
Convoluted but it could work if I can get a reference to the filename being
processed.
