Zig Upgrader and Version Manager

Upgrades to the latest version of Zig, or manages more versions of Zig on the same machine, supporting all platforms including RISC-V, 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 zigup up.

Platforms: macos-x86_64, macos-aarch64, freebsd-x86_64, linux-x86, linux-x86_64, linux-aarch64, linux-armv7a, linux-powerpc64le, linux-riscv64, windows-x86, windows-x86_64, windows-aarch64.

Getting Started

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

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

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

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

zigup install latest

Upgrade both the installer script and the Zig language, if they're not the latest versions, and delete the previously active latest version from the disk too:

zigup up

Installation

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

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

Both the zigup and zig 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 Zig binary directory to PATH, for example:

$HOME/.zigup:$HOME/.zig:$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.

Locations

Path	Description
`~/.zigup`	directory with the installer script and versions of Zig
`~/.zig`	symbolic link to the currently active version of Zig

For example, with the Zig 0.13.0 activated:

/home/prantlf/.zigup
  ├── 0.12.0   (another version)
  ├── 0.13.0   (linked to /home/prantlf/.zig)
  └── zigup    (installer script)

Usage

zigup <task> [version]

Tasks:

  current              print the currently selected version of Zig
  latest               print the latest version of Zig for download
  local                print versions of Zig ready to be selected
  remote               print versions of Zig available for download
  update               update this tool to the latest version
  upgrade              upgrade Zig 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 Zig
  uninstall <version>  remove the specified version of Zig
  use <version>        use the specified or the latest version of Zig
  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.

Debugging

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 zigup ...

You can debug the installer too:

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

Platform Detection

Environment Variables

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

Variable	Default value
`PLATFORM`	detected using `uname`
`OS`	part of `PLATFORM` before `-`
`ARCH`	part of `PLATFORM` after `-`
`TOOL_URL_LIST`	https://ziglang.org/download/index.json
`TOOL_URL_DIR`	https://ziglang.org/download
`INST_DIR`	`$HOME/.zigup`
`TOOL_DIR`	`$HOME/.zig`
