如何从 MMT 中的结构访问常量和符号?
How do I access constants and notations from structures in MMT?
鉴于以下理论,为了小型 MWE 的目的将无意义的东西形式化,
theory Meta : http://cds.omdoc.org/urtheories?LF =
ℕ: type ❙
prop: type ❙
or: prop ⟶ prop ⟶ prop ❘ # 1 ∨ 2 ❙
❚
theory S : ?Meta =
c: ℕ ⟶ ℕ ⟶ prop ❘ # 1 + 2 ❙
d: ℕ ⟶ ℕ ⟶ ℕ ⟶ prop ❘ # 1 |- 2 ∶ 3 ❙
❚
在声明了两个 S
结构后,如何访问 S
中的内容?
theory T : ?Meta =
structure s1 : ?S = ❚
structure s2 : ?S = ❚
n: ℕ ❙
// How do I access constants c, d and their notations from s1, s2?
❚
常量可通过 <structure name>/<constant name>
获得
theory T : ?Meta =
structure s1 : ?S = ❚
structure s2 : ?S = ❚
n: ℕ ❙
c_usage1 = s1/c n n ❙
c_usage2 = s2/c n n ❙
c_usage_combined = (s1/c n n) ∨ (s2/c n n) ❙
d_usage1 = s1/d n n ❙
d_usage2 = s2/d n n ❙
d_usage_combined = (s1/d n n) ∨ (s2/d n n ) ❙
❚
符号在 第一个 表示标记
前添加 <structure name>/
例如,定义为# 1 + 2
的表示法只有一个presentation marker+
,因此通过... <structure name>/+ ...
访问。
另一方面,定义为 # 1 |- 2 ∶ 3
的符号有两个表示标记:|-
和 ∶
。通过 ... <structure name>/|- ... ∶ ...
:
