Package Exports
- esrecurse
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (esrecurse) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Esrecurse 
Esrecurse (esrecurse) is ECMAScript recursive traversing functionality.
Example Usage
The following code will output all variables declared at the root of a file.
esrecurse.visit(ast, {
XXXStatement: function (node) {
this.visit(node.left);
// do something...
this.visit(node.right);
}
});We can use Visitor instance.
var visitor = new esrecurse.Visitor({
XXXStatement: function (node) {
this.visit(node.left);
// do something...
this.visit(node.right);
}
});
visitor.visit(ast);We can inherit Visitor instance easily.
function DerivedVisitor() {
esrecurse.Visitor.call(/* this for constructor */ this, /* visitor object. */ this);
}
util.inherits(DerivedVisitor, esrecurse.Visitor);
DerivedVisitor.prototype.XXXStatement = function (node) {
this.visit(node.left);
// do something...
this.visit(node.right);
};And you can invoke default visiting operation inside custom visit operation.
function DerivedVisitor() {
esrecurse.Visitor.call(/* this for constructor */ this, /* visitor object. */ this);
}
util.inherits(DerivedVisitor, esrecurse.Visitor);
DerivedVisitor.prototype.XXXStatement = function (node) {
// do something...
this.visitChildren(node);
