Numbering only second-level headlines in export

Numbering only second-level headlines in export

[Jarmo Hurri]

Greetings.

What - if any - would be the recommended way to implement numbering only
second-level headlines in an exported document with running numbering
(resets with first-level headline change)?

BTW, here is a full programming course (used to teach kids of different
ages) written almost entirely with org:

The generation of the front page utilizes a couple of shell scripts,
some javascript and R, but it's all org otherwises. The entire source
code can be found here:

All the best,

Jarmo

You haven't said what export target you are using.  In any case, I would
suggest you look at using a counter.  See section 12.5 of the org manual
but specifically:

‘{{{n}}}’
‘{{{n(NAME)}}}’
‘{{{n(NAME,ACTION)}}}’
     This macro implements custom counters by returning the number of
     times the macro has been expanded so far while exporting the
     buffer.  You can create more than one counter using different NAME
     values.  If ACTION is ‘-’, previous value of the counter is held,
     i.e.  the specified counter is not incremented.  If the value is a
     number, the specified counter is set to that value.  If it is any
     other non-empty string, the specified counter is reset to 1.  You
     may leave NAME empty to reset the default counter.

I would turn off numbering of headings (num:nil option) and then have
the counter in each second level heading.

Brilliant, that worked like a charm on first trial. Thanks!

(BTW, my export target is html.)
