G-Portugol

About the Language

G-Portugol is a dialect of the Portugol pseudo-code language (or structured Portuguese), which is widely used to describe algorithms in Portuguese in a simple and natural way. In general, books dedicated to teaching algorithms, logic, and data structures use some form of this language.

The purpose of G-Portugol is to provide an implementation of the Portugol language, offering tools for editing, compiling, running, and debugging programs written in this language. It is designed to support students taking their first steps in software development, as well as teachers of computer science–related courses. Therefore, its focus is primarily educational.

Currently available are a compiler, translator, and interpreter for the language (GPT), as well as a simple visual environment (GPTEditor) that allows editing, execution, and debugging of programs written in G-Portugol. The first is multi-platform and can generate executables for MS Windows and GNU/Linux systems, while the second is available only for the KDE 3.0 environment on GNU/Linux.

The GPT Program

GPT is the program that implements the G-Portugol language, allowing users to:

  • compile algorithms;
  • translate algorithms into C;
  • execute algorithms in interpreted mode;
  • debug algorithms interactively.

Although usable, GPT is not immune to bugs. In addition, some features may still be missing. Therefore, contributions are welcome — feel free to send suggestions, feedback, source code, patches, ideas, and algorithms that are not being processed correctly by GPT.

Available on Debian and Ubuntu

GPT is available in the official Debian repositories and in the official Ubuntu repositories. This allows easy installation using the APT package manager.

To install GPT, run:

sudo apt install gpt

After installation, the gpt command will be available in the terminal, allowing you to compile, translate, run, and debug programs written in G-Portugol.

gpt -i /usr/share/doc/gpt/examples/olamundo.gpt
