Link to 1 Link to 1 #+END_EXAMPLE to #+BEGIN_EXAMPLE html

Link to 1 Link to 1 #+END_EXAMPLE Looking at `org-html-link`, `org-export-get-reference` is only called to get the _internal_ reference. That works perfectly fine already, and I am quite happy with the way org mode generates labels/ids for the exported code. That should, however, have no influence of the link description (called `desc` in the code in `org-html-link`), which is the thing that I actually want to change? In summary, my exported output is supposed to look like that: #+BEGIN_EXAMPLE html

Link to test_fun Link to another_test_fun #+END_EXAMPLE Regards, timor 2016-06-17 13:56 GMT+02:00 Nicolas Goaziou : > Hello, > > timor writes: > >> Why is the link text set to "1" in both cases? > > This is just a nonsensical number because Org does not know what to > number.
