# 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));

```

```

```
