Validation for langid?

[pauloney]

Would it be possible (or desirable) to add a validation for the value of langid at the Biber level?

From my point f view it would be really nice. It is too easy to make a mistake, or typo, that can go undetected...

A Biber-side validation of langid values would require a list of supported languages. But at least in principle language modules for babel/polyglossia can be loaded more or less directly from a file without announcing them further first. So such a list would not only be a hassle to maintain, it also has the potential to yield wrong results even if it is up-to-date with what is available on CTAN, say.

But isn't that exactly the use-case for a 'Warning' ? Something that is not fatal and will not stop processing, but will warn the user that something is amiss. This happens to the ISBN validation on every run. The ISBN validator knows almost nothing about: - ISBNs issued in China, Brazil, South Africa ... - old ISBNs - newly issued ISBNs So when I run biber, I always get a warning about lots of them and I keep an eye on it to make sure no new ones are creeping in. I update the list frequently to get all the new numbers, and override what I got from CTAN. Overall it is, in the end, a very useful feature. It is true you can load a language with your own files, your own name and your own invented langid, but that is a LOT rarer than an ISBN that is not in the current list. Paulo Ney

... and in retrospect, biber already does many other validations of entries, and things like:

edition = {Second},
year = {1957-58},

get their own Warnings. So adding one more for langid would just been in line with what
is nortmally done.

People that load a whole new language by file and with a fake langid SHOULD get at least
a warning....
