Variables ¶
var Counter <-chan *big.Int
stream of pointers to big integers for renaming variables
Functions ¶
func AtomicFormula ¶
Types ¶
type Compound ¶
type Compound struct {
Functor string
Id *big.Int
Prio int
EMap *EnvMap
IsActive bool
Args []Term
// contains filtered or unexported fields
}
func CopyCompound ¶
type Term ¶
func Assignexpr ¶
<expression> | <variable> ':=' <exspression>
func Factor_name ¶
<bi_0 name> | <name>'(”)' | <name> '(' <expression> [',' <expression>]0..n ')'
func NewCompound ¶
func ReadString ¶
func RenameAndSubstitute ¶
Substitute: replace variables in the term t with their bindings in the env or in the Build-In environment (BIVarEqTerm), if they are bound. If their are not bound rename the body-varaible of the rule (very late renaming). Follows variable chains, so that if a variable is bound to a variable, the second variable is also substituted if it is bound in env, recursively.
func Substitute ¶
Substitute: replace variables in the term t with their bindings in the env, if they are bound. Follows variable chains, so that if a variable is bound to a variable, the second variable is also substituted if it is bound in env, recursively.
func SubstituteBiEnv ¶
Substitute: replace variables in the term t with their bindings in the Build-In environment (BIVarEqTerm), if they are bound. Follows variable chains, so that if a variable is bound to a variable, the second variable is also substituted if it is bound in env, recursively.
type Variable ¶
type Variable struct {
Name string
// contains filtered or unexported fields
}
