Build Custom Stars Rating Column.

[oren64]

I build custem stars column (text) from number float column using this function.

def evaluate(self, formatter, kwargs, mi, locals, r):
	try:
		m = float (r)
		n = int(m)
		if 0.00 <= m - n <= 0.25:
			x = n * '★' 
		if 0.25 < m - n <= 0.75:
			x = n * '★' +'½'
		if 0.75 < m - n <= 1.00:
			x = (n+1) * '★'
	except:
		x = ''
	return x

It works well but I have a few question:

- Is there a way to use an half star in text?

- The funny thing is that in the catrgory is show half stars rating, but it doesn't show any books.

- From 2.67 there is half star option in the custem star column, can I build star column from float column?

Just create a custom rating column with half stars then click on each entry in your existing rating column in the tag browser and use the bulk metadata edit dialog to apply that rating value to the new column.

Thanks kovidgoyal, I didn't think of that.

But the good thing aboat star function, is that whan i download rating matadata as flaot number (with Goodread_rating) it automaticly create rating in stars, too bad there isn't an option to build column stars.
