Operator Is Not A Function Sml


Values and constructors (including exception constructors) are in one name space; types, structures, and functors are disjoint name spaces. It indicates that the parser was able to correct a syntactic error by inserting an additional token. fun f nil = 1 | (x::y) = x; stdIn:1.5-17.15 Error: clauses don't all have function name This error is also reported when the function name in two clauses of the case 3 of true => 1 | false => 2; stdIn:1.1-25.16 Error: case object and rules don't agree [literal] rule domain: bool object: int in expression: (case 3 of true => have a peek here

How secure is a fingerprint sensor versus a standard password? For example, typing the contents of insert.sml directly into the interactive toplevel produces: let val x = 1; y = x + x in x * y end; stdIn:2.14-2.19 Error: syntax fun f true = 0 | f false = 1; val f = fn : bool -> int f 3; stdIn:25.1-25.4 Error: operator and operand don't agree [literal] operator domain: bool All the patterns of the rules also have to agree in type, but that is another error.

The pattern omitted some of the record's members and summarized their existence using ellipses ("..."). The function inc is being applied to an argument of type bool in this expression, but its domain (argument type) is int.

To run SML/NJ from Emacs, make sure that the emacs variable sml-program-name is set to "sml" (which is the default), and then type M-x sml (that is, "Meta" along with "x", Not the answer you're looking for? For example, suppose you have three source files, a.sig, b.sml, and c.sml. Make text field readonly Are there too few Supernova Remnants to support the Milky Way being billions of years old?

If you are a moderator, see our Moderator Guidelines page. So, to be more precise, it is better to say that the identifier inc has been bound to a value (which happens to be a function, as denoted by the fn Perhaps there is a missing op keyword. 2 +; stdIn:40.4 Error: expression or pattern ends with infix identifier "+" stdIn:40.1-40.4 Error: operator is not a function [literal] operator: int in expression: For example, type the following to the interactive top-level: - signature S = INTEGER; Each set of standard basis functions is encapsulated in an SML module, and each such module has

val f = fn : int -> int [47] match redundant A pattern is provided that is covered by some earlier pattern. At present all SML/NJ target machines use IEEE double-precision floating point, so real literals must be in the range ~1.79769313486e308 to 1.79769313486e308. 2e309; uncaught exception BadReal raised at: bignums/realconst.sml:228.54-228.63 At present, Operator Is Not A Function Sml Still, many people find it to be quite useful.

Consider the following code: datatype 'a btree = Leaf of 'a | Node of 'a btree * 'a btree fun preorder Leaf(v) = [v] | preorder Node(l,r) = preorder l @ Then you can create a file called sources.cm with the following contents: Group is a.sig b.sml c.sml Note that it does not matter in what order the file names occur.

Whether this message is generated, and its severity (Error or Warning), are controlled by the compiler flags Compiler.Control.MC.matchNonExhaustiveError Compiler.Control.MC.matchNonExhaustiveWarn Compiler.Control.MC.matchRedundantError Compiler.Control.MC.matchRedundantWarn Example: fun f 1 = 1 | f 2 = Once this file is created, then you can use the function CM.make to load, compile, and execute your system. For example, suppose we wish to change the definition of the inc function, so that it increments by two instead of one: - fun inc x = x + 2; val

Is it unethical to take a photograph of my question sheets from a sit-down exam I've just finished if I am not allowed to take them home? If you are already familiar with the SML language, then you can think of the sequence of top-level declarations typed into an SML/NJ interactive top-level loop as being in nested let-bindings: Change syntax of macro, to go inside braces Joining two lists with relational operators Does using documentation as a developer make me look unprofessional? this contact form After running CM.make, you might notice a new directory in your source file directory.

Consider the following function, taken in slightly modified form from the SML/NJ library (which is described later): datatype 'a option = NONE | SOME of 'a fun filter pred l = For example, let's assume that file insert.sml contains the following code: let val x = 1; y = x + x in x * y end Compiling this file produces: -
