Author in cover image

[AstroCalibre]

Hi
When I generate the cover image of a book, the author's name appears at the bottom of the cover in the form "Last Name, First Name" (e.g. "Asimov, Isaac"). I want it in the form "First Name Last Name", without a comma and with the Last Name First Name reversed (e.g. "Isaac Asimov").
How can I do?
Thanks for attention,
Regards

Your Authors column must be in that format
And your author-sort must be set to copy.

The template is on the Text tab of The Generate cover: Customize
but any thing you do there is going to be fragile as it handles many conditions of Authors

theduck, thanks for your ansewer!
I hoped that it could be done without changing the ordering of the authors (I want to leave it in the form "Asimov, Isaac"), by modifying, for example, the template in Generate cover.

Alternatively, I tried to do this: I created a custom column (#myauthors) and manually inserted the authors' names into it in the form that I want (e.g. Isaac Asimov & Arthur Clarke). Then I edit the template in Generate cover replacing the word "authors" with "#myauthors". It works but I was wondering if it is possible to create a custom column that generates automatically the names of the authors, without comma between surname and name, with surname and name inverted, and separated by an ampersand.

Why are you generating the cover instead of downloading a cover for the book?

This footer template works for me

program:
# Show at most two authors, on separate lines.
authors = '';
for aut in sublist($authors, 0, 2, ' & ') separator '&':
	aut = swap_around_comma(aut);
	authors = list_join(' & ', authors, ' & ', aut, ' & ')
rof;
authors = list_re(authors, ' &amp; ', '(.+)', '<b>\1');
authors = re(authors, ' &amp; ', '<br>');
re(authors, '&amp;&amp;', '&amp;')

It works but I was wondering if it is possible to create a custom column that generates automatically the names of the authors, without comma between surname and name, with surname and name inverted, and separated by an ampersand.

Do what the above template does to generate the author list in the custom column. Something like this:

program:
authors = '';
for aut in $authors separator '&':
	aut = swap_around_comma(aut);
	authors = list_join(' & ', authors, ' & ', aut, ' & ')
rof;
authors

EDIT: Here are simpler versions of the above templates that use list_re_group() instead of a for loop.

Cover template:

program:
# Show at most two authors, on separate lines.
authors = list_re_group($authors, ' & ', '.', '(.*)', 'program: swap_around_comma($)');
num = count(authors, ' & ');
authors = sublist(authors, 0, 2, ' & ');
authors = list_re(authors, ' &amp; ', '(.+)', '<b>\1');
authors = re(authors, ' &amp; ', '<br>');
re(authors, '&amp;&amp;', '&amp;')

Custom column template:

program:
list_re_group($authors, ' & ', '.', '(.*)', 'program: swap_around_comma($)')

Hi, chaley, very thanks for your answer, it helped me a lot.
I have tried both code (cover template and custum column template).
The code for custom column works perfectly also with multiple authors.
The code for Generate cover works well with single author, but with multiple authors such as "Asimov, Isaac & Clarke, Arthur" produce "Isaac Clarke & Arthur Asimov", or something like that.

Hi JSWolf,
I have a lot of anthology, and I create an empty book for each story in the anthology. For this books I need to create a custom cover.

Works fine for me with your example authors, tested with both templates.

The book's metadata:


The generated cover (using the second template):


Don't know why it isn't working for you.

What version of calibre are you running?

chaley, forgive me, now I tried again, and it works!
I don't understand why it was giving me the wrong output before.
Thanks for your help!
