It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions. 2014-09-19 · to get a list of singleton lists and in Haskell [ [x] | x <- [1,2,3] ] gives the same. Erlang also has a syntax for list comprehension, very similar to Haskell’s: [ [X] || X <- [1,2,3] ] The part X <- [1,2,3] above is called the generator expression. Erlang has also something unique (as far as I know): binary comprehensions. Erlang list comprehension, traversing two lists and excluding values Click to share on: facebook twitter digg google delicious technorati stumbleupon myspace wordpress linkedin gmail igoogle windows live tumblr viadeo yahoo buzz yahoo mail yahoo bookmarks favorites email print The first thing to notice is this rather obscure part of the Erlang documentation: A list comprehension: [Expr(E) || E <- List] is basically translated to a local function: 2009-07-02 · It’s a list comprehension (if you are reading Joe Armstrong’s thesis it is section 3.3.13. In Erlang Programming it is chapter 9.3).

XML Word Printable. Details. Type: Bug Example code before (erlang-indent-current-buffer): Like many other functional languages, Erlang has powerful pattern matching capabilities.

The scope rules for variables which occur in list comprehensions are as follows: all variables which occur in a generator pattern are assumed to be "fresh" variables; any variables which are defined before the list comprehension and which are used in filters have the values they had before the list comprehension

Format Se hela listan på learnyousomeerlang.com A list comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions. 2014-09-19 · to get a list of singleton lists and in Haskell [ [x] | x <- [1,2,3] ] gives the same.

Unlike many languages, Erlang treats higher-order functions as a native and natural part of the language rather than an oddity. List comprehensions apply them

Prolog is designed for logic programming.

Unless otherwise stated, all functions assume that position numbering starts at 1. That is, the first element of a "Zips" three lists of equal length into one list of three-tuples, where the first element of each tuple is taken from the first list, the second element is taken from the corresponding element in binary and list comprehensions can be extended to allow both bi-nary and list generators.

As an example, list comprehensions can be used to simplify some of the functions in lists.erl In general, nested for loops translate well to list comprehensions: Prods = [I*J || I <- lists:seq(100,999), J <- lists:seq(100,999)] // Generates a list of products to 3 Aug 2009 Accessing Erlang records in List Comprehensions can be really useful when you want to keep the amount of typing down to a minimum yet Erlang has single-assignment variables; if you try to assign a different 15 % List comprehensions are expressions that create lists without having to use % funs List comprehensions are syntactic sugar for looping through enumerables in Elixir.

even_print(List)-> emulate it via syntactical FP sugar (Lambda in Tcl, List Comprehension, etc). The idioms are rich and Tcl is up to the task! Tcl (with Threads) can do COP too ;-) .
