Char bar = 'Z' quux : Bool quux = False An Idris file consists of an optional module declaration (here module Prims) followed by an optional list of imports and a collection of declarations and must have a type declaration, for example see x : Int, foo : String, from the above listing. New declarations must begin at the same level of indentation as the preceding declaration. Alternatively, a the front of another list (x :: xs). In the declaration for List, we used an infix operator ::. New operators such as this can be added using a fixity declaration, as follows: infixr 10 :: Functions, data

indication of what that name denotes and connotes. ## I n C++: A declaration is an introduction w/ partial information. A definition is a declaration w/ complete information. Depending on what's being named Declared first and (usually) defined later/elsewhere: Any extern or any forward (e.g., class C;) declaration. • Defined right away: • Any type aliases (typedef/using) or namespace names. Never defined a special meaning when appearing in a certain context." ## Now back to declarations • A declaration not only introduces names (for later use): It also “specifies the interpretation and semantic

This is useful for overriding the default setting in the configuration file. • b : Show all procedure declarations if an overloaded function error occurs. • x : Show information about the executable debug information. -gt Trash local variables. This writes a random value to local variables at procedure start. This can be used to detect uninitialized variables. The t can be specified multiple times variables. MACPROCVARS Use mac-style procedural variables. REPEATFORWARD Implementation and Forward declaration must match completely. POINTERTOPROCVAR Allow silent conversion of pointers to procedural variables

symbol declared as a name for a variable, type, procedure, etc. The region of the program over which a declaration applies is called the scope of the declaration. Scopes can be nested. The meaning of an identifier between the preceding backtick token and the character literal. This special case ensures that a declaration like proc 'customLiteral' (s: string) is valid. proc 'customLiteral' (s: string) both zero-terminated and have a length field. One can retrieve the length with the built-in len procedure; the length never counts the terminating zero. The terminating zero cannot be accessed unless the
