Using Inko's version manager

ivm is a tool used to install and manage different versions of Inko, independent from your system's package manager. ivm is written in Rust.

Requirements

Rust 1.78 or newer
The dependencies necessary to build Inko from source

Installing

Arch Linux

yay -S ivm

Fedora

sudo dnf install dnf-plugins-core
sudo dnf copr enable yorickpeterse/inko
sudo dnf install ivm

Nix

ivm is available in the unstable channel:

nix-channel --add https://nixos.org/channels/nixpkgs-unstable nixpkgs-unstable
nix-channel --update
nix-shell -p ivm

From source

Clone the repository:

git clone https://github.com/inko-lang/ivm.git
cd ivm
cargo build --release

The resulting executable is found in target/release/ivm.

Using crates.io

If a package is available for your platform, we recommend installing ivm through your platform's package manager instead. Once ivm is available on enough platforms, we may stop publishing it to crates.io.

cargo install ivm

This installs the ivm executable in $HOME/.cargo/bin, where $HOME is your home directory. You need to add this to your shell's PATH if not done already:

export PATH="$HOME/.cargo/bin:$PATH"  # Using Bash
fish_add_path --path $HOME/.cargo/bin # Using Fish

For more information, refer to this rustup documentation page.

To update ivm, run the following:

cargo install ivm --force

Setting up your PATH

Once ivm is installed, you need to add its bin path to your PATH variable. This is needed to ensure that executables such as inko are available. To add the path, run ivm show bin, then add the path it prints out to your PATH variable. For example:

$ ivm show bin
/var/home/yorickpeterse/homes/fedora/.local/share/ivm/bin

Assuming you're using Bash as your shell, you'd add the following to your .bashrc:

export PATH="$HOME/.local/share/ivm/bin:$PATH"

Usage

To install a version (e.g. 0.10.0):

ivm install 0.10.0    # This will install version 0.10.0
ivm install latest    # This will install the latest available version

Make sure to set a default version after installing Inko, otherwise you have to use ivm run VERSION inko ... to use Inko.

Make sure the dependencies necessary for your platform are installed, and that any required environment variables are set before running ivm install.

To remove a version:

ivm remove 0.10.0    # This will remove version 0.10.0
ivm remove latest    # This will remove the latest _installed_ version

To list all installed versions:

ivm list

To list all available versions:

ivm known

To change the default Inko version:

ivm default 0.10.0

To remove any temporary data:

ivm clean

To run a command with a specific Inko version:

ivm run 0.10.0 inko --version # This will run `inko --version` using Inko 0.10.0
ivm run latest inko

To remove all data of ivm (except the ivm executable itself):

ivm implode

For more information, run ivm --help.

Setting a default version

The default command is used to set a default Inko version to use. When set, ivm will create a symbolic link in its bin/ directory to the inko executable of the default version. By setting a default version you can just use inko ... instead of the much more verbose ivm run VERSION inko ....
