Cafezinho Compiler

This repository contains the implementation of a didactic compiler for the Cafezinho language, developed as part of the activities for the Compilers - 1 course in the Bachelor's Degree in Computer Science at the Federal University of Goiás.

Project Structure

• Lexical Analyzer: Implemented using Flex, generating C code.
• Syntax Analyzer: Implemented using Bison.
• Intermediate Representation: Abstract syntax tree (ternary).
• Final Compilation: The syntax analyzer uses the lexical analyzer to process the input code and generate the syntax tree.

Features

1. Lexical Analysis: Identification of tokens based on the definitions of the Cafezinho grammar.
2. Syntax Analysis: Construction of the abstract syntax tree from the tokens generated in the lexical analysis.
3. Execution: Generation of an executable that processes input files containing code in Cafezinho.

Limitations

• The symbol table has not been implemented.
• Complete semantic analysis has not been performed.
• The final Assembly code has not been generated.

Project Files

• lexico.l: Specification file for the Flex lexical analyzer generator.
• Sintatico.y: Specification file for the Bison syntax analyzer generator.
• Makefile: Commands for generating the lexical and syntax analyzers, compiling, and linking the main program.

Usage Instructions

To compile and run the project, follow these steps:

1. Compile the project:

   make

2. Run the analyzer:

   ./cafezinho <input_file>
