lua.generator
Lua code generator, turns AST from lua.parser ( or a hand-made one ) back into Lua code.
Parentheses are added where operator priorities require them, so hand-made ASTs do not need Paren nodes.
Comments are not part of the AST and are not generated.

lua.generator.generate | Generates Lua code from an AST node. |
#lua.generator.formatNumber
function lua.generator.formatNumber(value: number): stringConverts a number into a Lua number literal that reads back as the same number.
