# Tesor — tiny packages caching proxy

Soon humanity will go to Mars and in order for the colonists to be able
to program, we will need a local mirror of packages.

## Installation

Please note that the project is in its infancy and
is **not** intended for production use.

**Debian/Ubuntu:**

```bash
sudo apt install curl gnupg

curl -fsSL https://pkg.dimidiumlabs.io/packages.gpg | sudo gpg --dearmor -o /usr/share/keyrings/dimidiumlabs.gpg
echo "deb [signed-by=/usr/share/keyrings/dimidiumlabs.gpg] https://pkg.dimidiumlabs.io/tesor/apt/ nightly main" | sudo tee /etc/apt/sources.list.d/tesor.list
sudo apt update && sudo apt install tesor

sudo systemctl enable --now tesor
```

**Fedora/RHEL:**

```bash
# DNF5 (Fedora 41+, RHEL 10+)
sudo dnf config-manager addrepo --from-repofile=https://pkg.dimidiumlabs.io/tesor/rpm/nightly/tesor-nightly.repo

# DNF4 (Fedora 40 and older, RHEL 8/9)
sudo curl -o /etc/yum.repos.d/tesor-nightly.repo https://pkg.dimidiumlabs.io/tesor/rpm/nightly/tesor-nightly.repo

sudo dnf install tesor
sudo systemctl enable --now tesor
```

**openSUSE:**

```bash
sudo rpm --import https://pkg.dimidiumlabs.io/packages.gpg
sudo zypper addrepo https://pkg.dimidiumlabs.io/tesor/rpm/nightly/ tesor-nightly
sudo zypper refresh
sudo zypper install tesor

sudo systemctl enable --now tesor
```

## Build from source

1. Provision the toolchain and system build dependencies: `mise bootstrap`
1. Build from source: `mise exec -- cargo build --release`
1. Install manually

    ```bash
    sudo groupadd --system tesor
    sudo useradd --system --gid tesor --no-create-home --shell /usr/sbin/nologin tesor
    sudo install -m 700 -o tesor ./pkg/tesor.toml     /etc/
    sudo install -m 755 -o root   ./pkg/tesor.service  /usr/lib/systemd/system
    sudo install -m 755 -o root   target/release/tesor /usr/local/bin/
    ```

1. start systemd service: `sudo systemctl enable --now tesor`
