Lua is a powerful, fast, lightweight, embeddable scripting language developed by a team at PUC-Rio, the Pontifical Catholic University of Rio de Janeiro in Brazil.

LibreCAD Scripting with lua

One of the scripting languages LibreCAD support's is [Lua]. Lua is the default scripting language and will be available for most simple scripting needs. Lua is very powerful but at the same time provides a easy to understand programming language. Please see Lua's reference manual for more information.

Example:

-- draw a line from coordinate 0,0 to coordinate 100,00

-- get the current document
currentDocument=app.currentDocument()

-- Use the Create operation to create new items within a drawing
ce = Create(currentDocument, "0")

-- Append a line
ce:append(Line(Coord(0,0), Coord(100,100)))

-- Append a circle
ce:append(Circle(Coord(0,0), 12))

-- Execute within the document
ce:execute()
