UVM

uvm(unified version manager) is a command-line tool for Linux, Windows and MacOS, it aims to provide convenient methods to manage multiple versions of development kit for various progamming languages.

• Linux/macOS (bash/zsh)

  for linux, 'gnu' is the default abi in target triple, if you are not sure what to use, use the default.

  $ curl -sSL https://raw.githubusercontent.com/jinyuli/uvm/master/install.sh | bash

  the script accepts one argument --abi.

  to enable uvm command in current shell

  $ source "$HOME/.uvm/env"

• Windows (pwsh)

  $ iwr https://raw.githubusercontent.com/jinyuli/uvm/master/install.ps1 -useb | iex

  the script accepts two parameters -abi(by default it's 'msvc') and -arch(by default it's 'x86_64')

• Linux/MacOS

  • Create a directory for uvm (recommended: ~/.uvm), download executable file from releases, and copy it to the bin subdirectory of the uvm directory (i.e. ~/.uvm/bin), rename it to uvm.
  • Update system PATH to include uvm path.

• Windows

  • Create a directory for uvm (recommended: ~/.uvm), download executable file from releases, and copy it to the bin subdirectory of the uvm directory (i.e. ~/.uvm/bin), rename it to uvm.exe.
  • Update system PATH to include uvm.exe path.

• list all released versions.
• list local installed versions.
• install a released version.
• use an installed version.
• create a virtual environment(venv) in a workspace.
• uninstall an installed version.

• list all released versions.
• list local installed versions.
• install a released version.
• use an installed version.
• create a virtual environment(venv) in a workspace.
• uninstall an installed version.

• support OpenJDK and Amazon Corretto.
• list all released versions.
• list local installed versions.
• install a released version.
• use an installed version.
• create a virtual environment(venv) in a workspace.
• uninstall an installed version.

update uvm to latest version:

$ uvm update

list all released versions of Golang:

$ uvm go list

list installed versions of Golang:

$ uvm go list --local
  1.20.1
* 1.20.10
  1.21.6

install Golang 1.21.6:

$ uvm go install -v 1.21.6

switch default global Golang version to 1.21.6:

$ uvm go use -v 1.21.6

switch default global Golang version to 1.21.6:

$ uvm go use -v 1.21.6

create a virtual environment with Golang 1.20.1 in current folder:

$ uvm go venv -v 1.20.1

by default this will create a folder named .venv

activiate virtual environment:

$ source ./.venv/activiate.sh
(go)$

deactiviate virtual environment:

$ source ./.venv/deactiviate.sh
$

Node has similar commands.

Java is a little different, each command must specify vendor with --vendor, currently supported vendors includs openjdk, corretto.

for example, install Java 20 from Amazon Corretto:

$ uvm java install -v 20 --vendor corretto

• configuration for uvm
• support mirrors
• support more languages
• show progress while downloading files
• support more shells for venv

Thanks to tools like nvm, n, rvm, g, using-virtual-environments for providing valuable ideas.
