# Python 3 Developer Environment Setup

{{>toc}}

## Windows

### Install Python

1. Download and install from [python.org](https://www.python.org/downloads/windows/). At the time of this writing, "Python 3.10.8" is recommended. During install note these options:

  1. Choose *Add python.exe to PATH*

  1. Choose *Disable path length limit*

1. In Windows settings, search "Manage app execution aliases" and:

  1. Disable *App Installer: python.exe*

  1. Disable *App Installer: python3.exe*

  1. Disable *App Installer: python3.7.exe*

1. Browse in explorer to `%AppData%\Local\Programs\Python\Python310` and copy `python.exe` to `python3.exe`

### Install Git

1. Download and install from [git-scm.org](https://git-scm.com/download/win). During installation take the defaults except for:

  1. Configuring the line ending conversions: choose *Checkout as-is, commit Unix-style line endings*

### Configure Git

From a command line:

1. `git config --global user.name "FIRST_NAME LAST_NAME"`

1. `git config --global user.email "MY_NAME@example.com"`

1. Optional, if you want to set an editor: `git config --global core.editor "PATH TO EDITOR"`

### Clone the chirp git repository (master branch)

From a command line:

```

C:\Users\{user}\Documents> git clone https://github.com/kk7ds/chirp

C:\Users\{user}\Documents> cd chirp

```

### Install the python dependencies

1. `python3 -m pip install -r requirements.txt`

1. `python3 -m pip install tox`

### Optional, but recommended: Install GitHub CLI

Via winget: `winget install --id GitHub.cli` or manually from [github.com](https://cli.github.com/)

Note: {user} as shown in paths above is the logged in Windows user

Note: The steps above were done on Windows 10 Pro, version 22H2

## MacOS

### Install command-line tools

```shell

$ xcode-select --install

```

### Clone the chirp git repository

```shell

$ git clone https://github.com/kk7ds/chirp

$ cd chirp

```

### Install python requirements

```shell

$ python3 -m pip install -r requirements.txt

$ python3 -m pip install tox

```

(Note that `tox` is only needed for running tests, not for running chirp itself)

### Run chirp

```shell

$ ./chirpwx.py

```

## Linux

These instructions are for Debian/Ubuntu, but should be generally applicable to other distros, possibly with different package names. You can use all distro packages (recommended), or install the python requirements with `pip install -r requirements.txt` but you probably want to get wxPython from distro packages.

### Install packages

```shell

$ sudo apt install git python3-wxgtk4.0 python3-serial python3-six python3-future python3-requests python3-pip

$ python3 -m pip install tox

```

(Note that `tox` is only needed for running tests, not for running chirp itself)

### Clone the chirp git repository

```

$ git clone https://github.com/kk7ds/chirp

```

### Run chirp

```shell

$ cd chirp

$ ./chirpwx.py

```

## Running tests

Below are some examples for running tests using tox. This is required to pass the CI checks on submissions before things can be merged.

Running everything:

```

$ tox

```

Running just style checks:

```

$ tox -e style

```

Running just driver tests for only drivers with changes since `origin/master`:

```

tox -e fast-driver

```

Running just one driver test by module name:

```

tox -e driver -- -k ic2820

```

Running all driver tests for a given vendor:

```

tox -e driver -- -k Icom

```
