# Development environment

## Debian/Ubuntu

Install dependencies:

```sh
sudo apt install -y podman dh-python python3 python3-pip python3-stdeb python3-pyside2.qtcore python3-pyside2.qtgui python3-pyside2.qtwidgets python3-appdirs python3-click python3-xdg python3-colorama
```

Install poetry (you may need to add `~/.local/bin/` to your `PATH` first):

```sh
python3 -m pip install poetry
```

Change to the `dangerzone` folder, and install the poetry dependencies:

```
poetry install
```

Build the latest container:

```sh
./install/linux/build-image.sh
```

Run from source tree:

```sh
# start a shell in the virtual environment
poetry shell

# run the CLI
./dev_scripts/dangerzone-cli --help

# run the GUI
./dev_scripts/dangerzone
```

Create a .deb:

```sh
./install/linux/build-deb.py
```

## Fedora

Install dependencies:

```sh
sudo dnf install -y rpm-build podman python3 python3-pip python3-setuptools python3-pyside2 python3-appdirs python3-click python3-pyxdg python3-colorama
```

Install poetry:

```sh
python -m pip install poetry
```

Change to the `dangerzone` folder, and install the poetry dependencies:

```
poetry install
```

Build the latest container:

```sh
./install/linux/build-image.sh
```

Run from source tree:

```sh
# start a shell in the virtual environment
poetry shell

# run the CLI
./dev_scripts/dangerzone-cli --help

# run the GUI
./dev_scripts/dangerzone
```

Create a .rpm:

```sh
./install/linux/build-rpm.py
```

## QubesOS

Create a Debian- or Fedora-based standalone VM with at least 8GB of private storage space, and follow the relevant instructions above.

Over time, you may need to increase disk space or prune outdated Docker images if you run into build issues on this VM.

## macOS

Install [Docker Desktop](https://www.docker.com/products/docker-desktop). Make sure to choose your correct CPU, either Intel Chip or Apple Chip.

Install the latest version of Python 3.10 [from python.org](https://www.python.org/downloads/macos/), and make sure `/Library/Frameworks/Python.framework/Versions/3.10/bin` is in your `PATH`.

Install Python dependencies:

```sh
python3 -m pip install poetry
poetry install
```

Install [Homebrew](https://brew.sh/) dependencies:

```sh
brew install create-dmg
```

Build the dangerzone container image:

```sh
./install/macos/build-image.sh
```

Run from source tree:

```sh
# start a shell in the virtual environment
poetry shell

# run the CLI
./dev_scripts/dangerzone-cli --help

# run the GUI
./dev_scripts/dangerzone
```

To create an app bundle, use the `build_app.py` script:

```sh
poetry run ./install/macos/build-app.py
```

If you want to build for distribution, you'll need a codesigning certificate, and then run:

```sh
poetry run ./install/macos/build-app.py --with-codesign
```

The output is in the `dist` folder.

## Windows

Install [Docker Desktop](https://www.docker.com/products/docker-desktop).

Install the latest version of Python 3.10 (64-bit) [from python.org](https://www.python.org/downloads/windows/). Make sure to check the "Add Python 3.10 to PATH" checkbox on the first page of the installer.


Install Microsoft Visual C++ 14.0 or greater. Get it with ["Microsoft C++ Build Tools"](https://visualstudio.microsoft.com/visual-cpp-build-tools/) and make sure to select "Desktop development with C++" when installing.

Install [poetry](https://python-poetry.org/). Open PowerShell, and run:

```
python -m pip install poetry
```

Change to the `dangerzone` folder, and install the poetry dependencies:

```
poetry install
```

Build the dangerzone container image:

```sh
python .\install\windows\build-image.py
```

After that you can launch dangerzone during development with:

```
# start a shell in the virtual environment
poetry shell

# run the CLI
.\dev_scripts\dangerzone-cli.bat --help

# run the GUI
.\dev_scripts\dangerzone.bat
```

### If you want to build the installer

* Go to https://dotnet.microsoft.com/download/dotnet-framework and download and install .NET Framework 3.5 SP1 Runtime. I downloaded `dotnetfx35.exe`.
* Go to https://wixtoolset.org/releases/ and download and install WiX toolset. I downloaded `wix311.exe`.
* Add `C:\Program Files (x86)\WiX Toolset v3.11\bin` to the path.

### If you want to sign binaries with Authenticode

You'll need a code signing certificate.

## To make a .exe

Open a command prompt, cd into the dangerzone directory, and run:

```
poetry run python .\setup-windows.py build
```

In `build\exe.win32-3.10\` you will find `dangerzone.exe`, `dangerzone-cli.exe`, and all supporting files.

### To build the installer

Note that you must have a codesigning certificate installed in order to use the `install\windows\build-app.bat` script, because it codesigns `dangerzone.exe`, `dangerzone-cli.exe` and `Dangerzone.msi`.

```
poetry run .\install\windows\build-app.bat
```

When you're done you will have `dist\Dangerzone.msi`.
