# TypeScript API Enhancements - Simplifier, Params, and ParamDescrs
This document describes the new APIs added to the Z3 TypeScript bindings to bring them to feature parity with Python, Java, C++, and C# bindings.
## Overview
Three new high-level APIs have been added:
1. **Params** - Parameter configuration objects
2. **ParamDescrs** - Parameter introspection and documentation
3. **Simplifier** - Modern preprocessing for incremental solving (Z3 4.12+)
These APIs address the gaps identified in [GitHub Discussion #8145](https://github.com/Z3Prover/z3/discussions/8145).
## Params API
The `Params` class allows you to create reusable parameter configuration objects that can be passed to tactics, simplifiers, and solvers.
### Features
- Create parameter objects with typed values (boolean, number, string)
- Pass to tactics via `tactic.usingParams(params)`
- Pass to simplifiers via `simplifier.usingParams(params)`
- Validate against parameter descriptions
- Convert to string for debugging
### Example
```typescript
const { Params, Tactic } = Context('main');
// Create a parameter object
const params = new Params();
params.set('elim_and', true);
params.set('max_steps', 1000);
params.set('timeout', 5.0);
params.set('logic', 'QF_LIA');
// Use with a tactic
const tactic = new Tactic('simplify');
const configuredTactic = tactic.usingParams(params);
// Validate parameters
const paramDescrs = tactic.paramDescrs();
params.validate(paramDescrs); // Throws if invalid
// Debug output
console.log(params.toString());
```
### API Reference
```typescript
class Params {
/**
* Set a parameter with the given name and value.
* @param name - Parameter name
* @param value - Parameter value (boolean, number, or string)
*/
set(name: string, value: boolean | number | string): void;
/**
* Validate the parameter set against a parameter description set.
* @param descrs - Parameter descriptions to validate against
*/
validate(descrs: ParamDescrs): void;
/**
* Convert the parameter set to a string representation.
*/
toString(): string;
}
```
## ParamDescrs API
The `ParamDescrs` class provides runtime introspection of available parameters for tactics, simplifiers, and solvers.
### Features
- Query available parameters
- Get parameter types
- Access parameter documentation
- Validate parameter configurations
### Example
```typescript
const { Simplifier } = Context('main');
// Get parameter descriptions
const simplifier = new Simplifier('solve-eqs');
const paramDescrs = simplifier.paramDescrs();
// Introspect parameters
const size = paramDescrs.size();
console.log(`Number of parameters: ${size}`);
for (let i = 0; i < size; i++) {
const name = paramDescrs.getName(i);
const kind = paramDescrs.getKind(name);
const doc = paramDescrs.getDocumentation(name);
console.log(`${name}: ${doc}`);
}
// Get all as string
console.log(paramDescrs.toString());
```
### API Reference
```typescript
class ParamDescrs {
/**
* Return the number of parameters in the description set.
*/
size(): number;
/**
* Return the name of the parameter at the given index.
* @param i - Index of the parameter
*/
getName(i: number): string;
/**
* Return the kind (type) of the parameter with the given name.
* @param name - Parameter name
*/
getKind(name: string): number;
/**
* Return the documentation string for the parameter with the given name.
* @param name - Parameter name
*/
getDocumentation(name: string): string;
/**
* Convert the parameter description set to a string representation.
*/
toString(): string;
}
```
## Simplifier API
The `Simplifier` class provides modern preprocessing capabilities for incremental solving, introduced in Z3 4.12. Simplifiers are more efficient than tactics for incremental solving and can be attached directly to solvers.
### Features
- Create simplifiers by name
- Compose simplifiers with `andThen()`
- Configure with parameters using `usingParams()`
- Attach to solvers for incremental preprocessing
- Get help and parameter documentation
### Example
```typescript
const { Simplifier, Solver, Params, Int } = Context('main');
// Create a simplifier
const simplifier = new Simplifier('solve-eqs');
// Get help
console.log(simplifier.help());
// Configure with parameters
const params = new Params();
params.set('som', true);
const configured = simplifier.usingParams(params);
// Compose simplifiers
const s1 = new Simplifier('solve-eqs');
const s2 = new Simplifier('simplify');
const composed = s1.andThen(s2);
// Attach to solver
const solver = new Solver();
solver.addSimplifier(composed);
// Use the solver normally
const x = Int.const('x');
const y = Int.const('y');
solver.add(x.eq(y.add(1)));
solver.add(y.eq(5));
const result = await solver.check(); // 'sat'
if (result === 'sat') {
const model = solver.model();
console.log('x =', model.eval(x).toString()); // 6
}
```
### API Reference
```typescript
class Simplifier {
/**
* Create a simplifier by name.
* @param name - Built-in simplifier name (e.g., 'solve-eqs', 'simplify')
*/
constructor(name: string);
/**
* Return a string containing a description of parameters accepted by this simplifier.
*/
help(): string;
/**
* Return the parameter description set for this simplifier.
*/
paramDescrs(): ParamDescrs;
/**
* Return a simplifier that uses the given configuration parameters.
* @param params - Parameters to configure the simplifier
*/
usingParams(params: Params): Simplifier;
/**
* Return a simplifier that applies this simplifier and then another simplifier.
* @param other - The simplifier to apply after this one
*/
andThen(other: Simplifier): Simplifier;
}
```
### Solver Integration
The `Solver` class has been extended with a new method:
```typescript
class Solver {
/**
* Attach a simplifier to the solver for incremental pre-processing.
* The solver will use the simplifier for incremental pre-processing of assertions.
* @param simplifier - The simplifier to attach
*/
addSimplifier(simplifier: Simplifier): void;
}
```
## Tactic Enhancement
The `Tactic` class has been enhanced with parameter configuration:
```typescript
class Tactic {
/**
* Return a tactic that uses the given configuration parameters.
* @param params - Parameters to configure the tactic
*/
usingParams(params: Params): Tactic;
/**
* Get parameter descriptions for the tactic.
* Returns a ParamDescrs object for introspecting available parameters.
*/
paramDescrs(): ParamDescrs;
}
```
### Example
```typescript
const { Tactic, Params } = Context('main');
const tactic = new Tactic('simplify');
const params = new Params();
params.set('max_steps', 100);
const configured = tactic.usingParams(params);
```
## Available Simplifiers
Common built-in simplifiers include:
- `'solve-eqs'` - Solve for variables
- `'simplify'` - General simplification
- `'propagate-values'` - Propagate constant values
- `'elim-uncnstr'` - Eliminate unconstrained variables
- `'ctx-simplify'` - Context-dependent simplification
Use `simplifier.help()` to see documentation for each simplifier and its parameters.
## Migration Guide
### Before (using global setParam)
```typescript
// Global parameter setting
setParam('pp.decimal', true);
// No way to create reusable parameter configurations
// No simplifier support
```
### After (using Params and Simplifier)
```typescript
// Reusable parameter objects
const params = new Params();
params.set('pp.decimal', true);
params.set('max_steps', 1000);
// Configure tactics
const tactic = new Tactic('simplify').usingParams(params);
// Use simplifiers for better incremental solving
const simplifier = new Simplifier('solve-eqs').usingParams(params);
solver.addSimplifier(simplifier);
```
## Compatibility
These APIs match the functionality available in:
- ✅ Python (`ParamsRef`, `ParamDescrsRef`, `Simplifier`)
- ✅ Java (`Params`, `ParamDescrs`, `Simplifier`)
- ✅ C# (`Params`, `ParamDescrs`, `Simplifier`)
- ✅ C++ (`params`, `param_descrs`, `simplifier`)
The TypeScript API now has 100% coverage of the Params, ParamDescrs, and Simplifier C APIs.
## Examples
See [simplifier-example.ts](./examples/high-level/simplifier-example.ts) for a complete working example demonstrating all features.
