@osamahammad21
Any update on this?

[osamahammad21]

@vijayank88 This is a low priority issue at the moment. It's not done yet. It would be a good first issue for new comers.

Do you mean camel case instead?
#2267 (comment) says EXCEPTEDGELENGTH should be rename to exceptEdgeLength but it's camel case not snake case.
snake case would give except_edge_length.

[osamahammad21]

Yeah sorry for misleading but we should use snake case not camel case:
except_edge_....

We roughly intend to follow the Google style (https://google.github.io/styleguide/cppguide.html#Type_Names) though have lots of code that doesn't.

Ah ok:
type name => camel case
variable => snake case
constant => camel case mac style
Pretty mixed style ;)
