如何使用 Jane Core 对列表进行排序?
How to sort a list using Jane Core?
我正在努力实现这个
open Core
let%test _ = List.sort ~cmp:Int.compare [1;2;3] = [1;2;3]
但是失败了
61 | let%test _ = List.sort ~cmp:Int.compare [1;2;3] = [1;2;3]
^^^^^^^^^^^
Error: The function applied to this argument has type
compare:('a -> 'a -> int) -> 'a list
This argument cannot be applied with label ~cmp
好的,我知道了。问题是谷歌搜索 ocaml 核心列表 导致我找到过时的文档。标签名称是 ~compare
所以这行得通
let%test _ = List.sort ~compare:Int.compare [1;2;3] = [1;2;3]

Janestreet Core 图书馆正在随时间改变其界面。关键字参数的旧名称为 cmp
,为了与库的其他部分保持一致,已更改为 compare
,
let%test _ = List.sort ~compare:Int.compare [1;2;3] = [1;2;3]
