I'm interested in the different kinds of identifier cases, and what people call them. Do you know of any additions to this list, or other alternative names?
myIdentifier : Camel case (e.g. in java variable names)MyIdentifier : Capital camel case (e.g. in java class names)my_identifier : Snake case (e.g. in python variable names)my-identifier : Kebab case (e.g. in racket names)myidentifier : Flat case (e.g. in java package names)MY_IDENTIFIER : Upper case (e.g. in C constant names)Names are either generic, after a language, or colorful; most don’t have a standard name outside of a specific community.
There are many names for these naming conventions (names for names!); see Naming convention: Multiple-word identifiers, particularly for CamelCase (UpperCamelCase, lowerCamelCase). However, many don’t have a standard name. Consider the Python style guide PEP 0008 – it calls them by generic names like “lower_case_with_underscores”.
One convention is to name after a well-known use. This results in:
…and suggests these names, which are not widely used:
Alternatively, there are illustrative names, of which the best established is CamelCase. snake_case is more recent (2004), but is now well-established. kebab-case is yet more recent and still not established, and may have originated on Stack Overflow! (What's the name for dash-separated case?) There are many more colorful suggestions, like caterpillar-case, Train-case (initial capital), caravan-case, etc.
