There are the following ways to invoke this command:
|
|
|
|
1. ``lua`` (without any parameters)
|
|
|
|
This starts an interactive lua interpreter.
|
|
|
|
2. ``lua -f "filename"`` or ``lua --file "filename"``
|
|
|
|
This loads and runs the file indicated by filename.
|
|
|
|
3. ``lua -s ["filename"]`` or ``lua --save ["filename"]``
|
|
|
|
This loads and runs the file indicated by filename from the save
|
|
directory. If the filename is not supplied, it loads "dfhack.lua".
|
|
|
|
4. ``:lua`` *lua statement...*
|
|
|
|
Parses and executes the lua statement like the interactive interpreter would.
