BOTH

NAME

both - Returns the list of keys and values of a context.

SYNOPSIS

both(variable);

DESCRIPTION

This function is used to return the list of keys and values of a context as a cotext. A context is an array in which instead of using numbers you use characters strings. Key contains the key name and, obviously, value contains the value. These are elements associated with the ones defined at the beginning(the keys).

If it is used as a function, it returns the list as an array.

If it is used as a callback, it returns each keys.

PARAMETERS

Variable

Specifies a variable of type context to list the keys and values.

RETURN

Array

An array of all keys and values if used as a function or each keys on a loop.

EXAMPLES

Note: In the following examples, the _ between the { should be removed to make it work.

res={_{ for i both({x:1,y:2}) do i; endfor; }}. return res={"key":"x","value":1}{"key":"y","value":2}.
res={_{ for i both({x:[1,3],y:{a:2,b:"4"}}) do i; endfor; }}. return res={"key":"x","value":[1,3]}{"key":"y","value":{"a":2,"b":"4"}}.
res={_{ a={x:1,y:2}; for i both(a) do i; endfor }}. return res={"key":"x","value":1}{"key":"y","value":2}.
res={_{ a={}; for i both(a) do i; endfor }}. return res=.
res={_{ for i both({}) do i; endfor }}. return res=.
res={_{ for i both(123) do i; endfor }}. return .*is not a context.*

res={_{ both({x:1,y:2}); }}. return res=[{"key":"x","value":1},{"key":"y","value":2}].
res={_{ a={x:1,y:2}; both(a); }}. return res=[{"key":"x","value":1},{"key":"y","value":2}].
res={_{ both({}); }}. return res=[].
res={_{ both(123); }}. return .*is not a context.*
res={_{ a={x:[1,3],y:{a:2, b:4}}; both(a); }}. return res=[{"key":"x","value":[1,3]},{"key":"y","value":{"a":2,"b":4}}].
