[ANSWERED] Where does Blender keep its list of acceptable ".left"/".right" strings, etc?

Hello,

I’m taking a look at blender’s armature naming code and I can’t find a list of names for different left/right/up/down etc. (henceforth referred to as chiral identifiers). I’d like to find a complete list of acceptable chiral identifiers (i.e., those that can be used with X-mirror*) so I can use them in my addon. I’m currently doing this by making the list editable by the user via a JSON file, that my addon reads with Python. It currently has all of the strings I can think of, but I don’t know if Blender understands all of them, or if Blender has more that I don’t know about.

*(of course X-mirror doesn’t handle .top or .bot etc, but maybe in the future there will be y-mirror and z-mirror. And either way, Blender’s auto-name bones has a feature for y/z axis, even if it isn’t functional with mirroring. So I’d like to handle those situations, too, but it’s not as important.)

I suppose the chiral identifiers might be handled by the translation? If so, is there a way to get a list in Python for custom naming scripts? Thanks.

Even if this is not possible, I’d like to have a full list of Blender’s chiral identifiers for English and other common languages. Any help finding this would be appreciated.

Looks like you want void BLI_string_flip_side_name
in blender/source/blender/blenlib/intern/string_utils.c

A quick glance says the identifiers are L and R, either upper or lower case.
Unlikely this will be internationalized, IMHO, due to the coding complications

Thanks! Even better, there are implementations of other string utilities much like the functions I wrote in my addon – and it looks like I’m doing them the right way! This is a great reference, thanks again!
