The Space Lua API provides functions for working with Lua expressions and templates.

spacelua.parseExpression(luaExpression)

Parses a lua expression and returns the parsed expression as an AST.

Example:

local parsedExpression = spacelua.parseExpression("1 + 1")

spacelua.evalExpression(parsedExpr, envAugmentation?)

Evaluates a parsed Lua expression and returns the result. Optionally accepts an environment table to augment the global environment.

Example: ${spacelua.evalExpression(spacelua.parseExpression("x + y"), {x = 1, y = 2})}

spacelua.interpolate(template, envAugmentation?)

Interpolates a string with lua expressions and returns the result. Expressions are wrapped in ${...} syntax. Optionally accepts an environment table to augment the global environment.

Example: {spacelua.interpolate("Hello {name}!", {name="Pete"})}
