LLM:LinuxSetup

Setup your dev env

Initial machine

To setup your machine you only need a fresh new Ledger computer configure by IT service If you have authorization you can disable sentinelone with :

    sudo systemctl disable sentinelone

Nano Support

On Linux, you will have to setup some udev rules as explained here GitHub - LedgerHQ/udev-rules: udev rules to support Ledger devices on Linux

node

install nvm https://github.com/nvm-sh/nvm#installing-and-updating

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
command -v nvm

find the node version used to build apps https://github.com/LedgerHQ/ledger-live-desktop/blob/develop/.github/workflows/bundle-app.yml

with:
  node-version: 14.x

Then find the latest on this version and install it

nvm ls-remote
nvm install x.x.x

You have npm installed by default with node but Live Team use yarn instead

npm install --global yarn

Configure Git

1 - ssh key

ssh-keygen -t ed25519 -C "firstname.lastname@ledger.com"
ssh-add ~/.ssh/id_ed25519
cat ~/.ssh/id_ed25519.pub

2 - GPG key

gpg --full-generate-key
gpg --list-secret-keys --keyid-format=long
gpg --armor --export YOUR_KEY_ID

git config --global commit.gpgsign true

3 - Install gh (Github cli) https://github.com/cli/cli

curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null
sudo apt update
sudo apt install gh

You will essentially use the command below to create PRs

gh pr create

VSCODE

install eslint extension and add this to your settings.json file

{
    ...
    "editor.formatOnSave": true,
    "eslint.format.enable": true,

      "source.fixAll.eslint": true
    }
}
