# SPECIAL INSTRUCTIONS FOR THE `/development` BRANCH

## Installation
### Python server
0. Install `uv` 
   - https://github.com/astral-sh/uv?tab=readme-ov-file#installation
1. clone the repo 
   - `git clone https://github.com/freemocap/freemocap`
2. Change directory to the repo: 
   - `cd freemocap`
3. **Change to the `development` branch:**
   - `git switch development`
4. Create virtual environment: 
   - `uv venv` 
5. Activate virtual environment
   - Windows: `.venv/bin/activate`
   - Mac/Linux: `source .venv/bin/activate`
6. Install dependencies
  - `uv sync` — installs skellytracker with NVIDIA GPU acceleration on Windows/Linux, or CPU-only on macOS, automatically
  - No supported GPU on Windows/Linux? Force the CPU-only build instead: `uv sync --no-default-groups --group cpu`
### React GUI
0. Install Node.js
   - https://nodejs.org/en/download/
1. Change directory to the `freemocap-ui` folder 
   - `cd freemocap-ui`
2. Install dependencies
   - `npm install`

## Run the FreeMoCap application in development mode 
1. Start the Python Server:
   - `python freemocap/__main__.py`
   - The server should start on `http://localhost:8005`
2. Start the React GUI:
   - `npm run dev`
   - An Electron window should pop up with the FreeMoCap GUI

## Build the FreeMoCap application 
(NOTE - This is not necessary for development, and does not handle the Python server yet)
1. Change directory to the `freemocap/freemocap-ui` folder
   - `npm run build`
   - The build will be in the `freemocap/freemocap-ui/releases` folder

## QUICKSTART

#### 0. Create a a Python 3.9 through 3.11 environment (python3.11 recommended)¶
#### 1. Install software via [pip](https://pypi.org/project/freemocap/#description):

`freemocap` requires the `cuda` or `cpu` extra to be specified — plain `pip install freemocap` will install without its tracker. Pick one:

```
pip install freemocap[cuda]   # Windows/Linux with an NVIDIA GPU
```

```
pip install freemocap[cpu]    # macOS, or Windows/Linux without a supported GPU
```

#### 2. Launch the GUI by entering the command:

```
freemocap
```

####  3. A GUI should pop up that looks like this:

#### 4. Have fun! It might break!  Work in Progress lol

#### 5. [Join the Discord and let us know how it went!](https://discord.gg/nxv5dNTfKT)

## Install/run from source code (i.e. the code in this repo)

This repo's dependencies (`skellytracker`, `skellycam`, etc.) are pulled from
private git repos via [`uv`](https://github.com/astral-sh/uv), so `conda` +
`pip install -e .` will not work here — use `uv` instead:

1) Install `uv`
   - https://github.com/astral-sh/uv?tab=readme-ov-file#installation

2) Clone the repository

```bash
git clone https://github.com/freemocap/freemocap
```

3) Navigate into the newly cloned/downloaded `freemocap` folder

```bash
cd freemocap
```

4) Create a virtual environment

```bash
uv venv
```

5) Install dependencies

```bash
uv sync
```

This installs `skellytracker` with NVIDIA GPU acceleration on Windows/Linux, or
CPU-only on macOS, automatically. If you're on Windows/Linux without a
supported GPU, force the CPU-only build instead:

```bash
uv sync --no-default-groups --group cpu
```

6) Launch the Python server

```bash
uv run python freemocap/__main__.py
```

The server starts on `http://localhost:8005`.

7) In a separate terminal, launch the React/Electron GUI (requires
   [Node.js](https://nodejs.org/en/download/)):

```bash
cd freemocap-ui
npm install
npm run dev
```

An Electron window should pop up with the FreeMoCap GUI!
