Configuration
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)

Examples

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
