Displaying genres and subgenres in manin view

This is template. Use in place of the one I gave earlier (in the new custom column).

That is what I did straight away, but it returned TEMPLATE ERROR and some gibberish.

So let me go through the process step by step:

1. Create a new custom column, selecting "Column built from other columns, behaves like tags.
2. Insert your code in the Template field.
3. Click OK and restart Calibre.

After I did the above, this is what I got in the new column:


Please mind I'm using version 3.48.

You need to upgrade for this to work.

OK, can't do that. Newer versions are not available for Windows 7 and upgrading the OS is not an option. Thank you for all your help.

OK, here is what I managed to do, using some ugly coding:

If I use the following as a template:

{#genre:subitems(0,1)}, {#genre:subitems(1,2)}, {#genre:subitems(2,3)}}

with the following metadata:

Speculative fiction.Fantasy, Speculative fiction.Science fiction.Steampunk

I get this result:

Speculative fiction, Fantasy, Science fiction, ,Steampunk

The problem here is that the first item hasn't got a third subitem, so the template returns ", ," in its place. Does anyone know an easy way to get rid of blank subitems? One that will work on Calibre 3.48?

Use

{#genre:'list_union('', re($, '\.', ','), ',')'}

Or if you want it sorted

{tags:'list_sort(list_union('', re($, '\.', ','), ','), 0, ',')'}

Oh yes. Nice one, @chaley. Thank you very much.
