File Tree Creator 🌳📂

A powerful CLI tool and library to generate file and folder structures from both tree diagrams and flat path lists. Perfect for quickly scaffolding projects or creating complex directory structures with a single command.

Features ✨

• Dual Input Modes: Supports both tree diagrams (│ ├── └──) and flat path lists
• Smart Parsing: Handles comments (lines starting with #) and validates paths
• Safe Operations: Skips existing files and validates path characters
• Recursive Creation: Automatically creates all necessary parent directories
• CLI & Programmable: Use via command line or import as a library

Installation 💿

Global Install (recommended for CLI usage)

npm install -g file-tree-creator

Local Project Install

npm install file-tree-creator --save-dev

Usage 🚀

CLI Usage

ftc <input-file> [--mode=tree|flat]

or

npx file-tree-creator <input-file> [--mode=tree|flat]

Examples:

1. From a tree diagram:

ftc structure.txt
# or explicitly
ftc structure.txt --mode=tree

2. From flat paths:

ftc paths.txt --mode=flat

Programmatic Usage

const { parseTreeDiagram, parseFlatPath, createFileStructure } = require('file-tree-creator');

// Using tree diagram
const treeInput = `
├── src
│   ├── index.js
│   └── utils
│       └── helper.js
`;
const paths = parseTreeDiagram(treeInput);
createFileStructure(paths, './my-project');

// Using flat paths
const flatInput = `
src/index.js
src/utils/helper.js
README.md
`;
const flatPaths = parseFlatPath(flatInput);
createFileStructure(flatPaths, './my-project');

Input Formats 📝

Tree Diagram Format

├── src
│   ├── index.js
│   └── utils
│       └── helper.js
├── README.md
└── .gitignore

Flat Path Format

src/index.js
src/utils/helper.js
README.md
.gitignore

Comments

Both formats support comments (lines starting with #):

# This is a comment
src/index.js  # This part will be parsed
# Another comment

API Reference 📚

parseTreeDiagram(treeText)

Parses a tree diagram string into an array of paths.

Parameters:

• treeText (String): The tree diagram text

Returns:

• Array of path strings

parseFlatPath(flatText)

Parses a flat path list into an array of paths.

Parameters:

• flatText (String): The flat path text

Returns:

• Array of path strings

createFileStructure(paths, baseDir = process.cwd())

Creates the file structure from an array of paths.

Parameters:

• paths (Array): Array of path strings
• baseDir (String): Base directory to create structure in (defaults to current directory)

Strict vs Lenient Modes

By default, the tool runs in lenient mode:

• Continues after errors
• Shows warnings for invalid paths
• Returns exit code 0 unless catastrophic failure occurs

Use --strict flag for strict mode:

• Fails immediately on first error
• Returns exit code 1 if any errors occur
• Recommended for CI/CD environments

Examples:

# Lenient mode (default)
ftc paths.txt

# Strict mode
ftc paths.txt --strict

Error Handling 🛑

The tool handles several error cases gracefully:

• Skips existing files/folders with warning
• Rejects paths with invalid characters (<>:"|?*)
• Rejects paths with double slashes (//)
• Provides clear error messages for file system operations

Examples 🏗️

See the examples/ directory for sample input files:

• tree.txt: Tree diagram example
• flat.txt: Flat path example
