Instances
exprNodeIoletCounter :: Env -> [ArgSpec] -> IoletCounter ExprNode Source
Counts the number of inlets and outlets for an ExprNode
exprToTree :: Expr -> ExprTree Source
treeToExpr :: ExprTree -> SuccFail Expr Source
Convert an expression tree (back) to an expression It will not give back the *same* expression in the case of an EList.
exprToReprTree :: Expr -> Tree String Source
unevalTree :: ExprTree -> ExprTree Source
