Description

This module is part of Speculate.

Exports utility functions of all utils sub-modules.

This is not intended to be used by users of Speculate, only by modules of Speculate itself. Expect symbols exported here to come and go with every minor version.

xs +- ys superimposes xs over ys.

1,2,3: +- [0,0,0,0,0,0,0] == [1,2,3,0,0,0,0]
x,y,z: +- [a,b,c,d,e,f,g] == [x,y,z,d,e,f,g] "asdf" +- "this is a test" == "asdf is a test"

sortOn :: Ord b => (a -> b) -> [a] -> [a] #

Sort a list by comparing the results of a key function applied to each element. sortOn f is equivalent to sortBy (comparing f), but has the performance advantage of only evaluating f once for each element in the input list. This is called the decorate-sort-undecorate paradigm, or Schwartzian transform.

Elements are arranged from from lowest to highest, keeping duplicates in the order they appeared in the input.

>>> sortOn fst [(2, "world"), (4, "!"), (1, "Hello")]
[(1,"Hello"),(2,"world"),(4,"!")]
