# JonPRL

Declarations from JonPRL, a Nuprl-family proof refinement logic for computational type theory.

## Source

## Schema

| Column | Type | Description |
|--------|------|-------------|
| fact | string | Verbatim declaration with the leading keyword removed: signature and body/proof joined |
| statement | string | Signature with the leading keyword removed (verbatim slice) |
| proof | string | `theorem`/`tactic`: the `{ .. }` tactic block; `definition`: the `=def= ..` body; empty otherwise |
| type | string | `theorem`, `operator`, `definition`, `notation`, or `tactic` |
| symbolic_name | string | Declaration identifier |
| library | string | Sub-library |
| filename | string | Repository-relative source path |
| imports | list[string] | Unused; always empty |
| deps | list[string] | Intra-corpus identifiers referenced |
| docstring | string | Unused; always null |
| line_start | int | First source line |
| line_end | int | Last source line |
| has_proof | bool | Whether a proof block was captured |
| source_url | string | Upstream repository |
| commit | string | Upstream commit extracted |

## Statistics

- Entries: 847
- With proof: 541 (63.9%)
- With docstring: 0 (0.0%)
- Libraries: 7

### By type

| Type | Count |
|---|---|
| theorem | 253 |
| operator | 244 |
| definition | 242 |
| notation | 62 |
| tactic | 46 |

## Example

```coq
bottom-diverges : [ ¬ bot ⇓ ] {
  unfold <not implies>;
  intro; aux {auto; unfold <has-value>; auto};
  bot-div #1
}.
```

- type: theorem | symbolic_name: `bottom-diverges` | example/approx.jonprl:13

## Use

Statement and proof are available both joined (`fact`) and split (`statement`, `proof`) for
proof-term modeling, autoformalization, retrieval, and dependency analysis via `deps`.
