Tuple Module

(tuple/brackets & xs)

Creates a new bracketed tuple containing the elements xs.

(tuple/join & parts)

Create a tuple by joining together other tuples and arrays.

(tuple/setmap tup line column)

Set the sourcemap metadata on a tuple. line and column indicate should be integers.

(tuple/slice arrtup [,start=0 [,end=(length arrtup)]])

Take a sub-sequence of an array or tuple from index `start` inclusive to index `end` exclusive. If `start` or `end` are not provided, they default to 0 and the length of `arrtup`, respectively. `start` and `end` can also be negative to indicate indexing from the end of the input. Note that if `start` is negative it is exclusive, and if `end` is negative it is inclusive, to allow a full negative slice range. Returns the new tuple.

(tuple/sourcemap tup)

Returns the sourcemap metadata attached to a tuple, which is another tuple (line, column).

(tuple/type tup)

Checks how the tuple was constructed. Will return the keyword :brackets if the tuple was parsed with brackets, and :parens otherwise. The two types of tuples will behave the same most of the time, but will print differently and be treated differently by the compiler.
