Grace Runtime Library

Welcome to the Grace Runtime Library repository! This repository contains the source code and documentation for the compiler library developed as part of the compilers course project at ECE-NTUA. The library is made to get a grade. It is designed to support the compilation of programs written in the Grace programming language.

About Grace Language

Grace is a language designed specifically for programmers to learn to program compilers. It’s small, concise, and amazingly powerful. Grace leaves out a lot of the boilerplate that lards other languages; this makes it easier for new students to focus on the essentials of programming. The primary goal of this project is to get a grade, and perhaps to develop a reliable and efficient compiler for the Grace language.

Features

• Written using C and its standard system libraries.
• Simple as is. No particular optimizations or advanced techniques used.
• Compatible with probably anything not Windows related.

Getting Started

Installation

1. Clone the repo

2. Build with make

3. Move library libgrc.a to your compiler directory

Usage

Link with clang :

clang program.asm libgrc.a

Example

gracec program.grc
clang -o a.out program.asm libgrc.a -no-pie

Documentation

Functions included (among others from stdlib):

• writeInteger(i64) -> void
• writeChar(i8) -> void
• writeString(ptr) -> void
• readInteger() -> i32
• readChar() -> i8
• readString(i64, ptr) -> void
• ascii(i8) -> i32
• chr(i64) -> i8
• strlen(ptr) -> i32
• strcmp(ptr, ptr) -> i32
• strcpy(ptr, ptr) -> void
• strcat(ptr, ptr) -> void
