Question

我在带有instance+[ ]nat和instantiation+[ ]nat的src / HOL文件夹上做了一个grep，也许我找到了所有已经为nat实例化的类型类。

由于我还要查看int，rat和real如何实例化，这很重要，如果有一个命令可以做到这一点很方便，例如{{1 }，它将显示类型类的依赖项。

下面，我在输入print_dependencies时，只需查看命令完成下拉框，即可显示我找到的所有打印和可视化命令。

我还展示了print_的实例化，我在根文件夹src / HOL的文件中找到了这些实例，其中章节与HOL文档相对应。

nat

可视化和打印命令：

subsection {* Nat class instantiations *}

  comm_monoid_diff
  comm_semiring_1_cancel
  linorder
  order_bot

Isabelle中的print_classes命令还列出了所有已定义的类，以及已将哪些类型实例化到类中。将输出复制到文件中，并通过grep命令运行它：

grep -F 'nat ::'

给出了nat已被实例化的类的列表，这是一个相当长的列表：

nat :: ab_semigroup_add
nat :: ab_semigroup_mult
nat :: bot
nat :: cancel_ab_semigroup_add
nat :: cancel_comm_monoid_add
nat :: cancel_semigroup_add

根据需要。

如何显示为nat，int等实例化的类型类？
