KiaraLang

About the project

Kiara is a simple language created for Building a Programming Language course.

Getting Started

Prerequisites

• Lua 5.3
• Luarocks
• LPeg luarocks install lpeg

Struct

• kiara\interpreter.lua: The start point of the language. By default it will print the AST and the code for the program that you pass. If you want to not display those info you need to edit run(params, true) to run(params, false)
• kiara\parser.lua: Responsible to parser the output of the kiara\grammar.lua
• kiara\debug.lua: A helper function to help us to debug the kiara\grammar.lua
• kiara\grammar.lua: The LPeg grammar for KiaraLang.
• kiara\compiler.lua: Generate the bytecode for the stack machine.
• kiara\build.lua: The language stack machine.

Usage

First read the Report to understand the language.

To run a .kiara program you need to run the following command:

lua kiara/interpreter.lua example.kiara

where example.kiara is the file that we want to run.

Tests

Exists a test for every functionally of the language in the file test.lua You can run the tests using the following commands:

lua test.lua or make tests

Roadmap

• Fix multidimensional arrays
• Implement support for strings
