Types ¶
type CommentOptimizer ¶ added in v0.0.7
type CommentOptimizer struct {
}
CommentOptimizer removes all comments from the code
type CompoundOptimizer ¶
type CompoundOptimizer struct {
// contains filtered or unexported fields
}
CompoundOptimizer wraps all other optimizers and executes them
func NewCompoundOptimizer ¶
func NewCompoundOptimizer() *CompoundOptimizer
NewCompoundOptimizer creates a new compound optimizer
type ExpressionInversionOptimizer ¶ added in v0.0.9
type ExpressionInversionOptimizer struct {
}
ExpressionInversionOptimizer inverts negated expressions to shorten them
func (ExpressionInversionOptimizer) Optimize ¶ added in v0.0.9
func (o ExpressionInversionOptimizer) Optimize(prog ast.Node) error
Optimize is needed to implement Optimizer
func (ExpressionInversionOptimizer) OptimizeExpression ¶ added in v0.0.9
func (o ExpressionInversionOptimizer) OptimizeExpression(e ast.Expression) ast.Expression
OptimizeExpression optimizes a single expression Optimize() in contrast can only optimize whole programms
type ExpressionOptimizer ¶ added in v0.0.10
type ExpressionOptimizer interface {
// OptimizeExpression optimizes the given expression. The expression is mutated
OptimizeExpression(prog ast.Expression) ast.Expression
}
ExpressionOptimizer is an additional optimizer interface, for optimizing single expressions
type Optimizer ¶
type Optimizer interface {
// Optimize optimizes the given ast. The ast is mutated (obviously)
Optimize(prog ast.Node) error
}
Optimizer is the common interface for all optimizers
type StaticExpressionOptimizer ¶
type StaticExpressionOptimizer struct {
}
StaticExpressionOptimizer evaluates static expressions at compile-time
func NewStaticExpressionOptimizer ¶
func NewStaticExpressionOptimizer() *StaticExpressionOptimizer
NewStaticExpressionOptimizer returns a new StaticExpressionOptimizer
func (*StaticExpressionOptimizer) Optimize ¶
func (o *StaticExpressionOptimizer) Optimize(prog ast.Node) error
Optimize is required to implement Optimizer
func (*StaticExpressionOptimizer) OptimizeExpression ¶ added in v0.0.10
func (o *StaticExpressionOptimizer) OptimizeExpression(e ast.Expression) ast.Expression
OptimizeExpression optimizes a single expression recursively
func (*StaticExpressionOptimizer) OptimizeExpressionNonRecursive ¶ added in v0.0.10
func (o *StaticExpressionOptimizer) OptimizeExpressionNonRecursive(exp ast.Expression) ast.Expression
OptimizeExpressionNonRecursive optimizes a single expression if no optimization is possible, nil is returned
type VariableNameOptimizer ¶
type VariableNameOptimizer struct {
// contains filtered or unexported fields
}
VariableNameOptimizer replaces variable names with sorter names Names of external variables will be left unchanged
func NewVariableNameOptimizer ¶
func NewVariableNameOptimizer() *VariableNameOptimizer
NewVariableNameOptimizer returns a new VariableNameOptimizer
func (*VariableNameOptimizer) Optimize ¶
func (o *VariableNameOptimizer) Optimize(prog ast.Node) error
Optimize is needed to implement Optimizer
func (*VariableNameOptimizer) OptimizeVarName ¶ added in v0.0.10
func (o *VariableNameOptimizer) OptimizeVarName(in string) string
OptimizeVarName replaces a variable name with a new one (if it does not reference an external variable) the same input name will always result in the same output name
