Upgrades to the latest version of Deno, or manages more versions of Deno on the same machine, supporting all platforms, as simple es rustup.

• Small. Written in bash, easily extensible.
• Fast. Downloads and unpacks pre-built binary builds.
• Portable. Writes only to the user home directory.
• Simple. Switches the version globally, no environment variable changes needed.
• Efficient. Just run denoup up.

Platforms: darwin-x86_64, darwin-aarch64, linux-x86_64, linux-aarch64, windows-x86_64.

Make sure that you have bash 4 or newer and curl available, execute the following command:

curl -fSs https://raw.githubusercontent.com/prantlf/denoup/master/install.sh | bash

Install the latest LTS version of Deno, if it hasn't been installed yet:

denoup install lts

Before you continue, make sure that you have the following tools available: curl, jq, ln, rm, uname, unzip. It's likely that jq will be missing. You can install it like this on Debian: apt-get install -y jq.

Upgrade both the installer script and the Deno language (to the latest LTS version), if they're not up-to-date, and delete the previously active latest LTS version from the disk too:

denoup up lts

If you specify latest instead of 'lts, the latest non-LTS version will apply.

Make sure that you have bash 4 or newer and curl available, execute the following command:

curl -fSs https://raw.githubusercontent.com/prantlf/denoup/master/install.sh | bash

Both the denoup and deno should be executable in any directory via the PATH environment variable. The installer script will modify the RC-file of the shell, from which you launched it. The following RC-files are supported:

~/.bashrc
~/.zshrc
~/.config/fish/config.fish

If you use other shell or more shells, update the other RC-files by putting both the installer directory and the Deno binary directory to PATH, for example:

$HOME/.denoup:$HOME/.deno/bin:$PATH

Start a new shell after the installer finishes. Or extend the PATH in the current shell as the instructions on the console will tell you.

For example, with the Deno 20.16.0 activated:

/home/prantlf/.denoup
  ├── 2.0.0   (linked to /home/prantlf/.deno)
  ├── 1.46.3  (another version)
  └── denoup  (installer script)

denoup <task> [version]

Tasks:

  current              print the currently selected version of Deno
  latest               print the latest version of Deno for download
  local                print versions of Deno ready to be selected
  remote               print versions of Deno available for download
  update               update this tool to the latest version
  upgrade              upgrade Deno to the latest and remove the current version
  up                   perform both update and upgrade tasks
  install <version>    add the specified or the latest version of Deno
  uninstall <version>  remove the specified version of Deno
  use <version>        use the specified or the latest version of Deno
  help                 print usage instructions for this tool
  version              print the version of this tool

You can enter just MAJ or MAJ.MIN as <version>, instead of the full MAJ.MIN.PAT. When using the install or use tasks, the most recent full version that starts by the entered partial version will be picked. When using the uninstall task, the least recent full version that starts by the entered partial version will be picked.

If you enable bash debugging, every line of the script will be printed on the console. You'll be able to see values of local variables and follow the script execution:

bash -x denoup ...

You can debug the installer too:

curl -fSs https://raw.githubusercontent.com/prantlf/denoup/master/install.sh | bash -x

The following environment variables can be set before running install.sh or denoup, if you know what you're doing:
