Can't get half-stars using rating_to_stars function

Phil_C · 05-28-2021, 10:19 PM

My plugboard places various items at the beginning of the Comments in the Details on a Kobo Clara.

The part of the template I'm having trouble with is this:

{#gr1:rating_to_stars(value,1)|<div>Rating: |</div><hr/>}

No half-stars show up, only whole stars. The rating comes from a custom column of floating point numbers. The ratings are from Goodreads and show up in the format x.xx in the custom column.

I must have something wrong, but I'm baffled, so I hope someone here can help. Thanks!

The word "value" shouldn't be there. In Single Function Mode the value is passed automatically.

EDIT: Just in case the above isn't clear, what you want is

Code:

{#gr1:rating_to_stars(1)|<div>Rating: |</div><hr/>}

I tried that during previous experimenting. Just tried again to make sure, but it is still not working. Here is the entire plugboard:

Code:

kepub:KOBOTOUCHEXTENDED = ([{#pg_ct:|<div>Pages: |; }{#wd_ct:|Words: |; }{pubdate:|Published: |</div>}{#last_read:|<div>Last Read: |</div>}{#gr1:rating_to_stars(1)|<div>Rating: |  }{#gr1:| |</div><hr/>}{comments}] -> comments)

I added the numerical value from the same column so you can see the rating of 3.88 in the image. Only 3 stars show, where I assume it should be 3.5 stars.

The function works. See this screen capture of the template being evaluated by the template tester.

My guesses are:

the book wasn't updated on the Kobo so you are seeing the old value. Edit: Clearly not the case since we are seeing the 3.88. Sorry about the noise.
the Kobo cannot display the 1/2 star character. What happens if you paste the 1/2 star character (⯨) (the character shows as a box on Windows Chrome) into the template like this (an image so the half-stars show)?

Edit2: here is a link to the unicode page for half-star.

Your guess is correct. The Kobo Clara HD cannot display the half-star. I added the code for a half-star and a full star to the template, updated the Kobo, and got a blank space where the half-star should be, followed by a full star.

So I will just stick with the numerical rating, which of course is more accurate anyway.

The best thing that came out of this is the Template Tester -- which I had no idea existed

(and does prove the star function works).

Thanks for your help.
