This script installs the latest GE-Proton, installs NonSteamLaunchers under one unique Proton prefix folder in your compatdata folder path called "NonSteamLaunchers" and adds them to your Steam Library. It will also add the games automatically on every steam restart. So you can use them on Desktop or in Game Mode.

• Automatic installation of the most popular launchers in your Steam Deck 🎮
• Handle automatically the download and installation of your chosen launchers and the games ⌚️
• MicroSD Support 💾 This script supports moving the entire prefix to a microSD. The script will install launchers and games to your SD card, and the launchers in Steam will point to the SD card installation. This allows you to save internal storage space on your Steam Deck!

"NSLGameScanner.service" is also live when you use this script and continues after the script is closed and even works after your Steam Deck has restarted. This works in the background as a service file to automatically add your games to your library on every Steam restart. Currently adds:

• Epic Games 🎮
• Ubisoft Connect 🎮
• EA App 🎮
• Gog Galaxy 🎮
• Battle.net 🎮
• Amazon Games 🎮
• Itch.io 🎮

• Go to desktop mode, right click the download button above and save the .desktop file to your Steam Deck desktop.
• Go to your desktop, click the NonSteamLaunchers icon, it will download and run the latest NonSteamLaunchers.sh from this repository and run it.
• You will simply have to choose which launcher to install and let the script handle the rest. 💻 No files are left in your "Downloads" they are deleted after installation.
• After running the script, launch Steam on your Steam Deck. You'll find the new launchers in your library under the non-steam tab. Click a launcher to see your installed games from that store, and launch them directly from Steam! If you have downloaded a game inside of your launcher, restart your Deck or quit and reopen Steam and the NSLGameScanner.service should add it to your library, even in gamemode! 🥳

Install Docker. Once installed, a clean dev environment with a Docker container native to VSCode is spun up automatically.

• Command palette (⇧⌘P) > Dev Containers: Reopen in Container
• F5 for debug
  • May need to select interpreter (e.g., /opt/venv/bin/python) first

VSCode Extensions (Dev Container)

• Atom Keymap
• Bash IDE
• Better Comments
• Docker
• EditorConfig
• GitHub Copilot
• GitHub Copilot Chat
• gitignore
• GitLens
• Markdown All in One
• MS Visual Studio Live Share
• Python
• Shellcheck

If VSCode isn't present or only the python portion (cf. __init__.py) is being worked on, it's possible to just run a Docker container on its own. The container installs the correct version of python and any dependencies (e.g., ipython, rich) in requirements.txt.

# navigate to directory with Dockerfile
cd .devcontainer/

# build image
docker build -t nonsteamlaunchers .

# run container
docker run -it --rm --name=mynonsteamlaunchers --workdir=/app -v $(pwd):/app nonsteamlaunchers bash

# exit container
exit

Useful for the python module(s), but extra compared to the dev container portion that covers the core shell script.

# create virtual environment
python -m venv .venv

# activate virtual environment
source .venv/bin/activate

# install dependencies
python -m pip install -r requirements.txt 

Pre-commit hooks are installed via pre-commit and are run automatically on git commit.

Most importantly, ruff is used to lint all python code.

• Install pre-commit
• Install pre-commit hooks

  pre-commit install

• Trigger pre-commit hooks automatically on git commit

  git add .
  git commit -m "commit message"

• Bypass pre-commit hooks
  • Sometimes, it's necessary to bypass pre-commit hooks. This can be done with the --no-verify flag.

    git commit -m "commit message" --no-verify

While not currently enforced, by using conventional commits, it's possible to automatically generate changelogs and version numbers via release-please.

To help with that, the commitizen tool can be installed.

# install cz
npm install -g commitizen cz-conventional-changelog

# make repo cz friendly
commitizen init cz-conventional-changelog --save-dev --save-exact
npm install

# add file to commit
git add .gitignore

# run cz
λ git cz
cz-cli@4.3.0, cz-conventional-changelog@3.3.0

TL;DR: The Ruff formatter is an extremely fast Python formatter, written in Rust. It’s over 30x faster than Black and 100x faster than YAPF, formatting large-scale Python projects in milliseconds — all while achieving >99.9% Black compatibility.

• While it runs automatically on commits, it can also be run manually

  # check for errors
  ruff check .
  
  # fix (some) errors automatically
  ruff check . --fix

• Add devbox 👌

• Install asdf
• Add plugins

  asdf plugin-add python

  asdf plugin add nodejs https://github.com/asdf-vm/asdf-nodejs.git

• Usage
  • Install local plugins in repo

    asdf install

  • Install specific plugins

    # install stable python
    asdf install python <latest|3.11.4>
    
    # set stable to system python
    asdf global python latest
