**LoopX uses a standard PEP 517 build process with setuptools as its build backend, requiring only Python ≥3.11 and pip to build wheels or install in editable mode—no external compilers or build tools needed.**

LoopX is a pure-Python package hosted at `huangruiteng/loopx` that follows modern Python packaging standards. The entire build process relies on the standard library and setuptools, making it straightforward to build from source for development or distribution.

## Overview of the LoopX Build System

The build configuration lives in [`pyproject.toml`](https://github.com/huangruiteng/loopx/blob/main/pyproject.toml) at the repository root. This file declares the build system requirements, package metadata, and console-script entry points.

```toml
[build-system]
requires = ["setuptools==83.0.0"]
build-backend = "setuptools.build_meta"

```

This configuration makes LoopX compatible with any PEP 517-compliant build front-end, including `pip`, `build`, and `pdm`.

## Prerequisites for Building LoopX

Before starting the build process, ensure you have:

- **Python 3.11 or newer**
- **pip** (usually bundled with Python)
- **Git** (to clone the repository)

No C compiler, Rust toolchain, or other external build tools are required.

## Step-by-Step Build Instructions

### 1. Clone the Repository

Retrieve the source code from GitHub:

```bash
git clone https://github.com/huangruiteng/loopx.git
cd loopx

```

### 2. (Optional) Use the Local Install Helper

For a quick local setup without modifying your global environment, run the helper script at [`scripts/install-local.sh`](https://github.com/huangruiteng/loopx/blob/main/scripts/install-local.sh):

```bash
./scripts/install-local.sh

```

This creates a thin launcher in `~/.local/bin` that points to your local source tree.

### 3. Build Wheel or Source Distribution

Install the PEP 517 builder and create distributable artifacts:

```bash
python -m pip install --upgrade build
python -m build

```

This generates two files in the `dist/` directory:
- `loopx-<version>-py3-none-any.whl` — the built wheel
- `loopx-<version>.tar.gz` — the source distribution

### 4. Install the Package

Choose the installation mode that fits your needs:

**Editable install (recommended for development):**

```bash
python -m pip install -e .

```

This creates a link to your source directory, so changes take effect immediately without reinstallation.

**Standard install from built wheel:**

```bash
python -m pip install dist/loopx-0.4.7-py3-none-any.whl

```

Use this for production deployments or when distributing to other machines.

### 5. Verify the Installation

LoopX provides a `loopx` console script defined in [`pyproject.toml`](https://github.com/huangruiteng/loopx/blob/main/pyproject.toml):

```toml
[project.scripts]
loopx = "loopx.entrypoint:main"

```

The `main` function in [`loopx/entrypoint.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/entrypoint.py) handles command dispatch. Verify everything works:

```bash
loopx doctor

```

A successful build reports clean environment checks. You can also run:

```bash
loopx status

```

This displays the current goal state if configured.

### 6. Run the Test Suite (Optional)

For contributors, validate your build by running tests:

```bash
python -m pip install "loopx[test]"
pytest -n auto

```

The `[test]` extra installs `pytest` and related dependencies declared in [`pyproject.toml`](https://github.com/huangruiteng/loopx/blob/main/pyproject.toml)'s `[project.optional-dependencies]` section.

## Complete Build Example

Here is the full workflow in one sequence:

```bash

# Clone and enter repository

git clone https://github.com/huangruiteng/loopx.git
cd loopx

# Build wheel (Python ≥3.11 required)

python -m pip install --upgrade build
python -m build

# Install in editable mode for development

python -m pip install -e .

# Verify CLI functionality

loopx doctor
loopx status

# Run full test suite

python -m pip install "loopx[test]"
pytest -n auto

```

## Key Build Files in LoopX

| File Path | Purpose |
|-----------|---------|
| [`pyproject.toml`](https://github.com/huangruiteng/loopx/blob/main/pyproject.toml) | Declares **setuptools** build backend, metadata, dependencies, and `loopx` console script |
| [`loopx/entrypoint.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/entrypoint.py) | Implements `main()` function invoked by the CLI |
| [`scripts/install-local.sh`](https://github.com/huangruiteng/loopx/blob/main/scripts/install-local.sh) | Helper for creating a local launcher without system-wide installation |
| `dist/` (generated) | Contains built wheel and source distribution artifacts |
| `tests/` | Test suite for validating builds and runtime behavior |

## Summary

- LoopX uses **setuptools** as its PEP 517 build backend with a minimal [`pyproject.toml`](https://github.com/huangruiteng/loopx/blob/main/pyproject.toml) configuration.
- The build process is **pure Python**—no external compilers or build tools required.
- Development workflows should use `pip install -e .` for editable installs.
- Production installs can use wheels built via `python -m build`.
- Verification is simple: run `loopx doctor` after installation to confirm correct setup.

## Frequently Asked Questions

### What Python version does LoopX require?

LoopX requires **Python 3.11 or newer**. This is enforced by the `requires-python` field in [`pyproject.toml`](https://github.com/huangruiteng/loopx/blob/main/pyproject.toml). Earlier Python versions will fail during package resolution.

### Can I build LoopX without installing the `build` tool?

Yes. While `python -m build` is the modern standard, you can still use `pip install -e .` directly for editable installs or `pip install .` for regular installs. The `build` tool is only needed when creating distributable wheels or source archives for publication.

### Where is the `loopx` command defined?

The `loopx` CLI entry point is declared in [`pyproject.toml`](https://github.com/huangruiteng/loopx/blob/main/pyproject.toml) under `[project.scripts]`, which maps to `loopx.entrypoint:main`. The actual implementation resides in [`loopx/entrypoint.py`](https://github.com/huangruiteng/loopx/blob/main/loopx/entrypoint.py) in the source tree.

### Does LoopX have any compiled extensions?

No. LoopX is a **pure-Python package** with no C, Rust, or other native extensions. This simplifies the build process and ensures compatibility across all platforms that support Python 3.11+.
