# Description
Adds functionality to the plugin interface to support calling internal
commands from plugins. For example, using `view ir --json`:
```rust
let closure: Value = call.req(0)?;
let Some(decl_id) = engine.find_decl("view ir")? else {
return Err(LabeledError::new("`view ir` not found"));
};
let ir_json = engine.call_decl(
decl_id,
EvaluatedCall::new(call.head)
.with_named("json".into_spanned(call.head), Value::bool(true, call.head))
.with_positional(closure),
PipelineData::Empty,
true,
false,
)?.into_value()?.into_string()?;
let ir = serde_json::from_value(&ir_json);
// ...
```
# User-Facing Changes
Plugin developers can now use `EngineInterface::find_decl()` and
`call_decl()` to call internal commands, which could be handy for
formatters like `to csv` or `to nuon`, or for reflection commands that
help gain insight into the engine.
# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`
# After Submitting
- [ ] release notes
- [ ] update plugin protocol documentation: `FindDecl`, `CallDecl`
engine calls; `Identifier` engine call response
