What qualifies as an identifier?
from buckaroo.
An identifier is valid if it passes this test:
x.length() > 1 && x.length() < 31 && x.matches("^[a-zA-Z]+[a-zA-Z0-9-_+]*$");
In English:
- At least one character long
- No more than 30 characters long
- Must start with a letter
- May contain numbers,
-
,_
or+
- Upper-case and lower-case are allowed
- No spaces
Some examples can found in the unit-tests.
We try to follow this-naming-convention
in the official cook-book.

Well, what do you mean by 'trim'?
from buckaroo.
In the CLI the user may enter an identifier surrounded by white-space. In this case, we should trim the input before checking if the identifier is valid.
