Class HilbertProofBuilder

A builder class for constructing Hilbert-style proofs. Provides a chainable API for adding proof steps.

Example

const proof = new HilbertProofBuilder(implicationAB)
	.addPremise(A, "First premise")
	.addPremise(B, "Second premise")
	.build();

constructor

new HilbertProofBuilder(goal: PropFormula): HilbertProofBuilder
Creates a new proof builder with a goal formula.
Parameters
- goal: PropFormula
  The target formula to prove
Returns HilbertProofBuilder
- Defined in propositional/hilbert-calculus/classes/hilbert-proof-builder.ts:29

Methods

addPremise

addPremise(formula: PropFormula, comment?: string): this
Adds a premise (given assumption) to the proof.
Parameters
- formula: PropFormula
  The premise formula
- Optionalcomment: string
  Optional explanation for the premise
Returns this
This builder instance for chaining
- Defined in propositional/hilbert-calculus/classes/hilbert-proof-builder.ts:39

addAxiom

addAxiom(payload: HilbertAxiomPayload, comment?: string): this
Adds an axiom step to the proof.
Parameters
- payload: HilbertAxiomPayload
  The axiom payload containing formulas and schema
- Optionalcomment: string
  Optional explanation for the axiom
Returns this
This builder instance for chaining
- Defined in propositional/hilbert-calculus/classes/hilbert-proof-builder.ts:50

addDerivedStep

addDerivedStep(payload: HilbertDerivedPayload, comment?: string): this
Adds a derived step to the proof using a Hilbert calculus rule.
Parameters
- payload: HilbertDerivedPayload
  The derived step payload containing formulas, schema, and step references
- Optionalcomment: string
  Optional explanation for the derivation
Returns this
This builder instance for chaining
- Defined in propositional/hilbert-calculus/classes/hilbert-proof-builder.ts:61

reiterateStep

reiterateStep(fromIndex: number, comment?: string): this
Reiterates (repeats) a previously proved step. Allows referring to a formula from an earlier step in the proof.
Parameters
- fromIndex: number
  The index of the step to reiterate (1-based)
- Optionalcomment: string
  Optional explanation for the reiteration
Returns this
This builder instance for chaining
- Defined in propositional/hilbert-calculus/classes/hilbert-proof-builder.ts:73

build

build(): HilbertProof
Constructs the proof and returns it.

Returns HilbertProof
The completed HilbertProof instance
- Defined in propositional/hilbert-calculus/classes/hilbert-proof-builder.ts:82

buildSteps

buildSteps(stepsFn: (builder: this) => void): this
Adds multiple steps in sequence using a callback function. Useful for building complex proofs programmatically.
Parameters
- stepsFn: (builder: this) => void
  A callback that receives the current builder and adds steps
Returns this
This builder instance for chaining
Example
```
proof.buildSteps((builder) => {
  builder.addPremise(p);
  builder.addAxiom(axiom1);
  builder.addDerivedStep(derived1);
});
```
- Defined in propositional/hilbert-calculus/classes/hilbert-proof-builder.ts:102

preview

preview(): HilbertProof
Gets the current state of the proof without building. Useful for inspection during construction.

Returns HilbertProof
The current HilbertProof instance
- Defined in propositional/hilbert-calculus/classes/hilbert-proof-builder.ts:112
