Hi Kenneth,
that makes sense. It took a bit of reading to understand that
'plural' is really a C function. I thougnt it was just a constant
like anything else in that file.
At the same time we have translations like this (en_GB):
msgid "%d × %d pixel"
msgid_plural "%d × %d pixels"
msgstr[0] "%d × %d pixel"
msgstr[1] "%d × %d pixels"
And the function f = plural(n) = (n!=1) has the two values:
n=0 => f(n) = 1 # 0 pixels
n=1 => f(n) = 0 # 1 pixel
n=2...inf => f(n) = 1 # 2 pixels
Ahh, so the f(n) is the index to msgstr. Ok, now i understand it.
I suppose there are some other translators that do not understand this.
I think the key to understanding this, is to realize that plural
is really a C function of n which is the numerical argument that
controls the textual context.
Also I had to know that the function plural is really the index
to the msgstr[0], msgstr[1] array.
Hope this helps understanding the plural function.
Thanks for your explanations.
