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

• Bash
• Zsh

1. Install luamb using pip:

   pip install [--user] luamb

   or pipx:

   pipx install luamb

2. Set up your shell — add the following to ~/.bashrc or ~/.zshrc:

   source <(luamb shellsrc)

3. Install hererocks:

   luamb update

luamb is configured via environment variables.

• LUAMB_HOME

  A directory where luamb stores its data (hererocks, environments, etc.). The default value is $XDG_DATA_HOME/luamb (usually ~/.local/share/luamb) on Linux and ~/Library/Application Support/luamb on macOS.

• LUAMB_ENVS_DIR

  A directory where luamb stores environments. The default value is $LUAMB_HOME/envs.

• LUAMB_LUA_DEFAULT

  A default Lua interpreter/version. The format is interpreter version_specifier, e.g., lua 5.3, luajit @v2.1, moonjit /path/to, raptorjit latest.

• LUAMB_LUAROCKS_DEFAULT

  A default LuaRocks version, e.g, latest, 3.11.0.

• LUAMB_DISABLE_COMPLETION

  Set to true to disable shell completions.

• LUAMB_PYTHON_BIN

  If the luamb executable is not in PATH, set LUAMB_PYTHON_BIN to the Python executable with the luamb package installed and change the shell initialization command:

  export LUAMB_PYTHON_BIN=/path/to/bin/python
  source <("$LUAMB_PYTHON_BIN" -m luamb shellsrc)

• Create an environment 'myproject' with the latest Lua 5.2, the latest LuaRocks and associate it with /home/user/projects/myproject:

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

• Create an 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 the latest LuaJIT 2.0 and the latest LuaRocks as default versions:

  export LUAMB_LUA_DEFAULT='luajit 2.0'
  export LUAMB_LUAROCKS_DEFAULT=latest

• Create an environment 'newenv' with the default versions and without associated project directory:

  luamb mk newenv

• Create an environment 'norocks' with the default Lua version and without LuaRocks (verbose mode):

  luamb mk norocks --no-luarocks --verbose

• Activate the 'newenv' environment:

  luamb on newenv

• Deactivate the current environment:

  luamb off

• Delete the 'myproject' environment (it will remove the environment directory only, not the project one):

  luamb rm myproject

• on | enable | activate — activate an environment
• off | disable | deactivate — deactivate the current environment
• mk | new | create — create a new environment
• rm | remove | del | delete — remove an environment
• info | show — Show the details for a single virtualenv
• ls | list — list all of the environments
• update — install/update the hererocks script
• shellsrc — print the shell initialization code
