Introduction
GAMBAS BASIC is an open-source, object-oriented dialect of BASIC designed for rapid application development (RAD) on Linux. Often compared to Microsoft Visual Basic (VB6) for its simplicity and ease of use, GAMBAS offers an accessible and efficient platform for building GUI applications, automating tasks, and even working with databases. While it might not be the ideal choice for large-scale production software, it has a solid niche as a tool for prototyping, side projects, and rapid software development. In this article, we’ll explore the strengths and weaknesses of GAMBAS, demonstrating why it’s worth learning and where it falls short.
What is GAMBAS BASIC?
GAMBAS (an acronym for “GAMBAS Almost Means BASIC”) is a fully object-oriented language that provides an integrated development environment (IDE), a graphical form designer, and a robust framework for developing software efficiently. It is written primarily for Linux, although it can run on BSD and other Unix-like systems. Unlike traditional BASIC implementations, GAMBAS includes modern programming features such as classes, inheritance, event-driven programming, and database integration.
The Advantages of GAMBAS BASIC
1. Rapid Development with an Intuitive IDE
One of GAMBAS’s biggest advantages is its fully integrated development environment (IDE), which resembles VB6 and offers an easy-to-use graphical interface. This makes creating forms, handling events, and connecting to databases significantly faster than using more complex frameworks.
Key features include:
- Drag-and-drop UI design
- Built-in form editor
- Auto-complete and syntax highlighting
- Debugging tools
This allows for quick prototyping, making GAMBAS an excellent tool for proof-of-concept applications, internal tools, and personal projects.
2. Object-Oriented Programming (OOP)
Unlike older BASIC implementations, GAMBAS is fully object-oriented. It supports:
- Class-based inheritance
- Encapsulation
- Modular programming
This means developers can create maintainable and scalable code structures, making it a better alternative than traditional procedural BASIC for modern applications.
3. Database Connectivity
GAMBAS provides native support for popular databases, including:
- MySQL/MariaDB
- PostgreSQL
- SQLite
- ODBC connections
Using GAMBAS for database-driven applications is relatively simple, as it abstracts much of the complexity and provides easy-to-use methods for executing SQL queries, managing connections, and handling transactions.
4. Scripting and Automation
GAMBAS can be used as a scripting language for automating tasks on Linux. It provides direct access to shell commands, making it useful for:
- Writing Linux utilities
- Automating system administration tasks
- Rapidly developing small GUI applications to manage Linux settings
5. Cross-Platform Compatibility (Sort of)
While primarily designed for Linux, GAMBAS programs can often run on BSD systems. The community has explored ways to port GAMBAS to Windows via Wine, but it is not a native solution. If you’re developing exclusively for Linux users, GAMBAS is a great choice.
6. Active Community and Open-Source Support
GAMBAS has a passionate open-source community that continuously improves the language, adds features, and provides support. The GAMBAS website and forums contain ample documentation and tutorials, making it easier for new users to get started.
The Drawbacks of GAMBAS BASIC
While GAMBAS excels in rapid development, it is not without limitations. Here are some factors to consider before choosing it for a project.
1. Linux-Only Support
If your application needs to run on Windows or macOS, GAMBAS is not the right choice. There is no native Windows support, and while it may run through Wine, this is far from an ideal solution.
2. Limited Adoption in the Industry
Unlike Java, Python, or C++, GAMBAS has a niche user base. This means:
- Fewer learning resources compared to mainstream languages
- Limited third-party libraries and extensions
- Harder to find skilled developers
For enterprise software or production systems requiring a long-term roadmap, GAMBAS might not be a viable choice.
3. Performance Concerns
GAMBAS is interpreted rather than compiled into native machine code. While it is fast enough for GUI applications and automation scripts, it is not ideal for high-performance computing, gaming, or applications requiring low-level optimizations.
4. Not a Web Development Language
GAMBAS is not designed for modern web applications. While you can build simple web-based applications using CGI scripting, it is far from a mainstream web framework like Django (Python) or Laravel (PHP).
GAMBAS in Action: A Simple Example
To demonstrate the simplicity of GAMBAS, let’s create a basic GUI application that connects to an SQLite database and retrieves data.
Step 1: Install GAMBAS
If you’re using Ubuntu or Debian-based distributions, install GAMBAS with:
sudo apt install gambas3
Step 2: Create a New Project
- Open GAMBAS IDE and create a new GUI application.
- Drag a Button and TextBox onto the form.
- Add the following code in the button click event:
Public Sub Button1_Click()
Dim Conn As New Connection
Dim Rs As Result
Conn.Type = "sqlite3"
Conn.Host = "./my_database.db"
Conn.Open
Rs = Conn.Exec("SELECT name FROM users WHERE id = 1")
If Rs.Available Then
TextBox1.Text = Rs!name
Else
TextBox1.Text = "No Data Found"
Endif
Conn.Close
End
Step 3: Run the Application
This simple app connects to an SQLite database, retrieves a user’s name by ID, and displays it in a textbox when the button is clicked.
When Should You Use GAMBAS?
Ideal Use Cases: ✅ Rapid prototyping ✅ Internal Linux tools ✅ Database front-ends ✅ Small personal projects ✅ Linux-specific GUI applications ✅ Educational programming
When to Avoid GAMBAS: ❌ Cross-platform software development ❌ High-performance applications ❌ Web development ❌ Large-scale enterprise applications
Conclusion
GAMBAS BASIC is an underrated yet powerful tool for rapid application development, particularly for Linux users. It provides a modernized version of BASIC with full OOP support, an intuitive IDE, and seamless database integration. However, its Linux-only nature and limited industry adoption mean it is not suitable for large-scale production software or cross-platform development.
For hobbyists, Linux developers, and those looking for a VB6-like experience in a modern Linux environment, GAMBAS is absolutely worth exploring. It serves as a fantastic tool for quickly building applications, automating tasks, and experimenting with graphical programming without the steep learning curve of more complex languages.
If you’re a Linux user looking for a rapid GUI development tool that’s both fun and productive, GAMBAS BASIC should definitely be in your toolbox.
