ngryman / tree-crawl Goto Github PK

Hey, this package does exactly what I need!
I'm using TypeScript, and although I can import JS directly, I'd like to have proper types for IntelliSense and stuff.

I'm happy to write the types myself. Would you be willing to integrate them into the repo? It's just an index.d.ts file in the root folder.
There're two alternatives: a file in the repo or a separate package @types/tree-crawl with that file if you don't want to officially support it.

I have a tree that sometime has a args property and sometimes has a content property. Is a way to set getChildren to more than one condition?

crawl(tree, n => console.log(n.type, n.value || n.op), {
  getChildren: node => node.args ||  node.content
});

I want to get the path to a leaf inside the tree. Do you have any recommended way to do this?

Similar to this method https://github.com/joaonuno/tree-model-js#get-the-node-path

Thanks for your work on this, great library 👌

Hello, How can I get string path to node ?
like 'children[3].rows[0]' etc
Thx

I am trying this, but does not work:

const tree = [5, 8, -3, 10]

crawl(tree, (node, context) => {
  if (node.valueOf() > 6) {
    console.log('TEST WORKS')
  }
})

How should it be done?

I am trying to update the top level element and getting the below error as it is not the children of any element.
Uncaught TypeError: Cannot read property 'children' of undefined

The code i written is

const idToSearch = 1;
const updatedValue = 'updated value';
crawl(records, (node, context) => {
if (idToSearch.id === node.id) {
const updatedNode = node;
updatedNode.name = updatedValue;
context.parent.children[context.index] = updatedNode; // eslint-disable-line no-param-reassign,max-len
context.replace(node);
}
});

I have a case in which I would like to arbitrarily suspend and later resume the iteration. I have a large tree structure, traversing through which would take a very long time and I would like to do it in 16 ms time slices to not block the UI and give live preview of the effect of traversal.

You can see my project here: https://github.com/mcalus3/open-fraksl (tree-crawl is used for rendering fractal elements, number of which multiplies with every depth level, that's why there is so much of them).

It would be helpful if you guide me, show where to add such a function and I would like to add it myself, as a pull request :)

I would like to use tree-crawl as an ES6 Module.
So far I have failed to build it – just changing the output format to 'es' does lead to a build error.

This package does not work in Node.js without an ESM bundling tool like Rollup or Webpack.

The main field of package.json points to a non-existent dist/tree-crawl.node.js file. See here.

Node then falls back to index.js which has ESM import statements, which causes a crash.

I am getting 'GulpUglifyError: unable to minify JavaScript' when gulp is trying to minify tree-crawl. It may be happening because of the files in dist folder are in es6 and gulp uglify accepts es5 code.
