Lua Version Manager - luaver

luaver helps to manage and switch between different versions of Lua, LuaJIT and Luarocks.

Features

1. Installs/Uninstalls any version of Lua, LuaJIT or luarocks with a single command.
2. Switches between different versions of 'Lua', 'LuaJIT' or 'Luarocks' easily, without glitches.
3. Consistency between 'Lua' and 'Luarocks' maintained - Rocks and configurations for different lua versions are stored differently.
4. Every terminal session can have a different environment configured. Default versions can also be configured.

Requirements

Requires make, either of wget or curl.

You may need to install some dependencies:

sudo apt-get install libreadline-dev 

Also, if you are planning to install older versions of Lua(which are 32-bit) on 64-bit machines, you may need to install some 32-bit libraries:

sudo apt-get install lib32ncurses5-dev

Installation

Install script

You can install from the script directly:

curl -fsSL https://raw.githubusercontent.com/dhavalkapil/luaver/master/install.sh | sh -- -r v1.0.0

Follow the instructions which appears after the luaver installation.

Install using git

1. Clone this repository into ~/.luaver:

   $ git clone https://github.com/DhavalKapil/luaver.git ~/.luaver

2. Add . ~/.luaver/luaver to your profile such as .bashrc or .zshrc:

   $ echo "[ -s ~/.luaver/luaver ] && . ~/.luaver/luaver" >> ~/.bashrc
   $ echo "[ -s ~/.luaver/completions/luaver.bash ] && . ~/.luaver/completions/luaver.bash" >> ~/.bashrc

3. Reload .bashrc or restart the shell to load luaver:

   $ . ~/.bashrc

Update using git

Note: This method only works if luaver was installed using git.

$ cd ~/.luaver && git fetch origin && git reset --hard origin/master

Additional works may be required.

Sample usage:

luaver install 5.3.1             # Installs Lua version 5.3.1
