luamb 0.2.0

Lua environment manager

Lua environment manager built on top of hererocks and inspired by virtualenvwrapper.

Supported shells

• Bash

• Zsh

Installation

1. Install luamb (hererocks will be installed automatically):

   $ pip install luamb

2. Create directory for environments:

   $ mkdir $HOME/.luambenvs

3. Configure your shell (add these lines to ~/.bashrc or ~/.zshrc):

   # path to directory with environments
   export LUAMB_DIR=$HOME/.luambenvs

   # optional variables:
   export LUAMB_LUA_DEFAULT=lua5.3        # default Lua version
   export LUAMB_LUAROCKS_DEFAULT=latest   # default LuaRocks version
   LUAMB_COMPLETION=true                  # enable Bash completion
   LUAMB_PYTHON_BIN=/usr/bin/python3      # explicitly set Python executable

   # make some magic
   source /usr/local/bin/luamb.sh         # default path in Debian if luamb has been installed globally

4. Try to execute in new shell:

   $ luamb --help

Examples

• Create environment ‘myproject’ with latest Lua 5.2 (5.2.4), latest LuaRocks and associate it with /home/user/projects/myproject:

  $ luamb mk myproject -l 5.2 -r latest -a /home/user/projects/myproject

• Create environment ‘jittest’ with LuaJIT 2.0.4, without LuaRocks and associate it with /home/user/projects/jitproj:

  $ luamb mk jittest -j 2.0.4 -a /home/user/projects/jitproj

• Set LuaJIT 2.0 (2.0.4) and latest LuaRocks version by default:

  $ export LUAMB_LUA_DEFAULT=luajit2.0
  $ export LUAMB_LUAROCKS_DEFAULT=latest

• Create environment ‘newenv’ with default versions and without associated project directory:

  $ luamb mk newenv

• Create environment ‘norocks’ with default Lua version (LuaJIT 2.0.4) and without LuaRocks (verbose mode):

  $ luamb mk norocks --no-luarocks --verbose

• Activate ‘newenv’ environment:

  $ luamb on newenv

• Deactivate current environment:

  $ luamb off

• Delete ‘myproject’ environment (it will remove env dir only, not project dir):

  $ luamb rm myproject
