- def differingPositions(exp1: Expr, exp2: Expr): List[HOLPosition]
Compares to Exprs and returns the list of outermost positions where they differ.
Compares to Exprs and returns the list of outermost positions where they differ.
- exp1
The first expression.
- exp2
The second expression.
- returns
The list of outermost positions at which exp1 and exp2 differ.

- def getPositions(exp: Expr, pred: (Expr) => Boolean = _ => true): List[HOLPosition]
Returns a list of positions of subexpressions that satisfy some predicate.
Returns a list of positions of subexpressions that satisfy some predicate.
This function is a wrapper around gapt.expr.util.LambdaPosition.filterPositions.
- exp
The expression under consideration.
- pred
The predicate to be evaluated. Defaults to "always true", i.e. if called without this argument, the function will return all positions.
- returns
Positions of subexpressions satisfying pred.

- def replace(exp: Expr, pos: HOLPosition, repTerm: Expr): Expr
Replaces a a subexpression in a Expr.
Replaces a a subexpression in a Expr. This function is actually a wrapper around util.LambdaPosition.replace.
- exp
The expression in which to perform the replacement.
- pos
The position at which to replace.
- repTerm
The expression that exp(pos) should be replaced with.
- def replace(f: Formula, pos: HOLPosition, repTerm: Expr): Formula
Replaces a a subexpression in a Formula.
Replaces a a subexpression in a Formula. This function is actually a wrapper around util.LambdaPosition.replace.
- f
The formula in which to perform the replacement.
- pos
The position at which to replace.
- repTerm
The expression that f(pos) should be replaced with.

- def toHOLPosition(exp: Expr)(pos: LambdaPosition): HOLPosition
Converts a LambdaPosition into the corresponding HOLPosition.
Converts a LambdaPosition into the corresponding HOLPosition.
Note that position conversion is always relative to a given expression.
- exp
The relevant Expr.
- pos
The position to be converted.
- returns
The corresponding HOLPosition.
- def toLambdaPosition(exp: Expr)(pos: HOLPosition): LambdaPosition
Converts a HOLPosition into the corresponding LambdaPosition.
Converts a HOLPosition into the corresponding LambdaPosition.
Note that position conversion is always relative to a given expression.
- exp
The relevant Expr.
- pos
The position to be converted.
- returns
The corresponding LambdaPosition.
- def toLambdaPositionOption(exp: Expr)(pos: HOLPosition): Option[LambdaPosition]
Converts a HOLPosition into the corresponding LambdaPosition, if one exists.
Converts a HOLPosition into the corresponding LambdaPosition, if one exists.
Note that position conversion is always relative to a given expression.
- exp
The relevant Expr.
- pos
The position to be converted.
- returns
The corresponding LambdaPosition.
