Grammatically correct double-noun identifiers, plural versions
- by Michal Czardybon
Consider compounds of two nouns, which in natural English would most often appear in the form "noun of noun", e.g. "direction of light", "output of a filter". When programming we usually write "LightDirection" and "FilterOutput".
Now, I have a problem with plural nouns. There are two cases:
1) singular of plural
e.g. "union of (two) sets", "intersection of (two) segments"
Which is correct, SetUnion and SegmentIntersection or SetsUnion and SegmentsIntersection?
2) plural of plural
There are two subcases:
(a) Many elements, each having many related elements, e.g. "outputs of filters"
(b) Many elements, each having single related element, e.g. "directions of vectors"
Shell I use FilterOutputs and VectorDirections or FiltersOutputs and VectorsDirections?
I suspect correct is the first version (FilterOutupts, VectorDirections), but I think it may lead to ambiguities, e.g.
FilterOutputs - many outputs of a single filter or many outputs of many filters?
LineSegmentProjections - projections of many segments or many projections of a single segment?
