Conditional Formatting

Conditional Formatting

[Craig Parker]

Is there a way to have pandoc help with conditional formatting? I'm 
going from markdown to html. If a list only contains top level items, 
for example:

<ul> <li> Blah </li> <li> Blah </li> <li> Blah </li> <li> Blah </li> </ul>

Then I'd want that list to have a different styling than one that has 
nested lists. I didn't know if there were some way to write a function 
or something. The styling and everything else I'd have covered.

If you're targeting HTML, then you'd style using CSS.
But I don't know if you can draw this distinction just
using CSS.

If not, you could use a lua filter that puts lists meeting
some condition in a special div with a class. That would give
you the CSS hook you need.

So if I define a ul.shallow and a ul.deep in my css, you're saying a lua 
filter would render (in the html) <ul class="shallow"> and <ul 
class="deep"> ?


Are creating lua filters anything like coding in other languages? I know 
bash and PHP...

No, I'm not saying that.

You could write a lua filter that would identify "shallow" and
"deep" lists, and insert a div with class "shallow" or "deep"
around the list.

Css could then have a rule like .shallow > ul or .deep > ul.

sort of, yes. See the documentation for lua filters on the pandoc
website.

You can of course do it manually with divs in your Markdown as well:

````markdown
:::shallow

-   a
-   b
-   c

:::

:::deep

-   A
-   B

    -   a
    -   b
    -   c

-   C

:::
````

and then in your CSS:

````css
div.shallow > ul { /* style here */ }

div.deep > ul { /* style here */ }
````

The main point is that Pandoc doesn't support attributes on most elements,
so you have to put block elements inside a div and inline elements inside a
span, set the attributes on the div/span and use a child selector in CSS.

I had no idea this was even possible. I was trying to make life easier 
for folks on my end that don't know html.  :::bob becoming <div 
class="bob"> will be awesome. I've got a meeting in 15 minutes -- going 
to sing some more pandoc praise (coworkers must be getting sick of me 
singing by now...)


Is this something specific to pandoc, github markdown, or what?

It's actually a pretty recent addition to Pandoc. You can do spans too! See <https://pandoc.org/MANUAL.html#divs-and-spans>.

Specific to Pandoc, it seems.

It is a behavior in Pandoc that is not specified in MarkDown dialects 
generally, or supported in other software currently.  

It is implemented in Pandoc as an extension, meaning that the behavior can 
be toggled.  Actually, I am confused about which extensions are enabled or 
disabled by default, but this one appears to work on a basic invocation of 
Pandoc.

While it seems ideally suited to your requirements as long as you are using 
Pandoc, you do ask the right question, and should be aware that results 
might be unpredictable with editors, readers, or other MarkDown 
converters.  

Yet, it seems to be one of the more useful features not part of common 
MarkDown dialects.

In a pinch you can use Pandoc to convert from a document using these 
extensions into a common dialect of MarkDown, suitable for ingestion by 
another converter.

I already took it and ran with it. A designer called for all top level 
list items to be bold. That's fine, unless the whole list is just top 
level items, then it looks funny. :::nobold takes care of that. And 
:::nonum addresses the next level being actual numerals. When we don't 
need numbered steps, we don't need numbers.

I'm sure there are a plethora of other uses I can find for it, but then 
I just need to make sure that it doesn't start getting confusing for folks.
