# Tree-Structurer
Gives you an overview of your Project structure
This is a Python package designed to display directory structures in a tree-like format. This tool provides an easy-to-read overview of the directory hierarchy, making it easier for developers to navigate complex project structures.
#### Installation
To install `tree_structurer`, you can use pip:
```bash
pip install pip install git+https://gitea.fabelous.app/Fabel/Tree-Structurer.git
```
#### Usage
You can run `tree_structurer` from the command line. By default, it will analyze the current directory and print its structure in a tree-like format. You can also specify a path to another directory.
To display the directory structure of the current directory:
```bash
python -m tree_structurer
```
To display the directory structure of a specific directory:
```bash
python -m tree_structurer /path/to/directory
```
#### Options
- `-v` or `--verbose`: Show more detailed output, including information about the path being analyzed.
Example:
```bash
python -m tree_structurer /path/to/directory -v
```
#### Important Files and Folders Ignored
By default, `tree_structurer` ignores files and folders that start with `_` or `.`. However, it does include the following exceptions:
- `__init__.py` and `__main__.py` files: These are considered important and will be included in the output.
- Special folders like `build`, `.git`, `node_modules`, etc.: These are also ignored to keep the output focused on the essential parts of the directory structure.
#### Example Output
```
dir Structure for /path/to/directory:
/path/to/directory
├── main.py
├── module1
│ ├── __init__.py
│ └── submodule1.py
└── utils
├── helper.py
└── constants.py
```
