Help using custom column templates

gabby98 · 07-17-2012, 05:10 PM

I am interested in making a few custom columns in my calibre library, but am having a few troubles getting it to work.

Can anyone give me an example of how I would use hascover() and how i could use test() to see if the Series Column has data? I tried, but it keeps saying field not found

please and thank you.

I am comfortable with most programming so usually once I see a few examples I am ok. I look forward to playing more with this system.

EDIT: OK,...I got the test() function to work after about another hour of playing. now just need help with hascover - will keep trying

Examples in general program mode.

has_cover: return 'yes' if the book has a cover, otherwise "no cover".

Code:

program: ifempty(has_cover(), 'no cover')

Testing if the series column has data: return 'Yes' if it does, otherwise return 'No'

Code:

program: test(field('series'), 'Yes', 'No')

Thank you...i got it now.

Determined the series think using a different format, but it still works. The hascover thing make sense now that i see the who "program: " option. I thought that was a notation thing
