stringify-tree

Convert a tree structure to an ASCII tree, in approximately the style of npm ls

This is in TypeScript, which helps since you pass it some functions.

install

npm install stringify-tree

trivial example

``typescript
import { stringifyTree } from "stringify-tree";

const tree = {
name: "Grandmarti", children: [
{
name: "Cyndi", children: [
{
name: "Jess", children: [
{ name: "Evelyn", children: [] },
{ name: "Linda", children: [] },
],
},
],
},
{ name: "Celia", children: [] },
],
};
console.log(stringifyTree(tree, t => t.name, t => t.children));
`

`
┬ Grandmarti
├─┬ Cyndi
│ └─┬ Jess
│ ├── Evelyn
│ └── Linda
└── Celia
`

real-life example

`typescript
import { stringifyTree } from "stringify-tree";

function treeNodeName(tn: TreeNode) {
const endOffset = tn.$value ? ", " + (tn.$offset + tn.$value.length) : "";
return [${tn.$offset}${endOffset}] ${tn.$name};
}
function treeNodeChildren(tn: TreeNode): TreeNode[] {
return tn.$children || [];
}

// parser stuff from Atomist. trust me, it makes a TreeNode with fields like the above

const ast = await Java9FileParser.toAst(p.findFileSync(path));
console.log(stringifyTree(ast, treeNodeName, treeNodeChildren));
