Locales -- managed Isar proof contexts, based on Pure predicates. |
29361 | 5 |
|
6 |
Draws basic ideas from Florian Kammueller's original version of |
|
7 |
locales, but uses the richer infrastructure of Isar instead of the raw |
|
8 |
meta-logic. Furthermore, structured import of contexts (with merge |
|
9 |
and rename operations) are provided, as well as type-inference of the |
|
10 |
signature parts, and predicate definitions of the specification text. |
|
11 |
||
12 |
Interpretation enables the reuse of theorems of locales in other |
|
13 |
contexts, namely those defined by theories, structured proofs and |
|
14 |
locales themselves. |
