npm install walkesvery simple walker for estree AST
$ npm install walkes
Or as a component:
$ component install Swatinem/walkes
walkes ~ 0.1.0 used to pass in the node as this. This changed with version~ 0.2.0 which passes it as the first parameter. Please keep that in mind, and
sorry for the inconvenience.
walkes works with an estree spec compatible
ast. You are free to choose whichever parser you would like, such as esprima,
espree, babel, acorn or others.
``jsrecurse()
walker(espree.parse("…"), {
MemberExpression: function (node, recurse, stop) {
// you are responsible to call on all the children yourselfwalker.checkProps
recurse(node.object);
recurse(node.property);
// or use to walk all child properties (also takes care of arrays)stop
walker.checkProps(node, recurse);
},
default: function (recurse, stop) {
// call or throw to completely stop walking.``
stop();
throw stop;
}
}, offset);
// when offset is set, will only recurse to nodes that lie within the offset
// esprima option {range: true} needs to be set for this to work
