When already bound variables are used in Erlang without any annotation, anyone reading a piece of code must first study it closely to understand which variables will be bound at the point of a pattern, before they can tell whether any pattern variable is a new binding or implies an equality assertion.

./t.erl:4: variable '_' is unbound. Stack Overflow Public questions and answers; Teams Private questions and answers for your team; Enterprise Private self-hosted questions and answers for your enterprise; Talent Hire technical talent; Advertising Reach developers worldwide 2 days ago In Erlang, all the variables are bound with the ‘=’ statement. All variables need to start with the upper case character. In other programming languages, the ‘=’ sign is used for the assignment, but not in the case of Erlang.

Variables are bound to values through the pattern matching mechanism. Pattern matching occurs when evaluating a function call, case - receive - try - expressions and match operator (=) expressions. The complete specification for the bit syntax appears in the Reference Manual.

_ is a special variable to which no value can be bound. No, unbound variables is by far the most common case in patterns, being how you introduce new variable bindings in Erlang. You don't want to annotate each and every one of those. 👍 4 👎 1 Any occurrence of a variable is bound to the right-hand value if it was previously unbound, otherwise it is pattern matched. Any type in Erlang can be bound to a variable. Erlang: Variables Unbound variables are only allowed in patterns. Variables start with an uppercase letter or In Erlang, the `if` is an expression which can have multiple branches The basic programming model consists of declare() (creates a new variable and returns its id), bind(x,v) (bind a variable x to value v) , and read(x).
