Simply Fortran

A user-friendly IDE for Fortran development with modern tools and features.

Comprehensive Fortran IDE for Modern Developers

Simply Fortran offers a complete integrated development environment focused on making Fortran programming accessible, efficient, and productive on Windows systems. Developed by Approximatrix, LLC, it caters to both experienced developers maintaining legacy projects and newcomers learning the language for high-performance scientific and engineering applications.

Rich Feature Set and Robust Tools

Simply Fortran provides a straightforward, well-organized interface that supports code editing, project management, and error detection. The editor includes syntax highlighting and code folding, making large codebases easier to read and navigate. A built-in project system helps developers structure complex applications, handling multiple source files and libraries with ease.

Of particular note is the integrated debugger, which allows step-by-step code execution, variable inspection, and setting of breakpoints—key features for troubleshooting intricate numerical and scientific algorithms. The intelligent error notifications in the editor minimize the time spent tracking down bugs or typos.

Powerful Compiler Integration

At its core, Simply Fortran uses the GNU Fortran compiler (GFortran), a modern and standards-compliant Fortran compiler. This ensures compatibility with a range of Fortran standards (including legacy FORTRAN 77 and more recent Fortran 90/95/2003 features). The compiler is tightly integrated, meaning code can be built and run directly from the IDE with a single command.

The built-in package manager simplifies adding external libraries and dependencies, which are often required for scientific computing. Advanced users can customize compile and link options to optimize performance for their specific hardware or workflow.

Simplified Installation and Support Resources

Simply Fortran is designed to be easy to install and update, with a single package that includes the editor, compiler, debugger, and all supporting tools. Comprehensive documentation is provided, along with active support forums and tutorials for both beginners and advanced users. This emphasis on usability assists those who may be new to Fortran or returning after a long hiatus.

Continued Relevance for High-Performance Computing

Despite the age of the language, many scientific and engineering fields continue to rely on Fortran for its numerical precision and speed. Simply Fortran is tailored for this audience, making it practical to maintain and modernize legacy codebases or start new projects leveraging Fortran's strengths.

Licensing Options

The software is available through paid licenses, with both single-user and network options suitable for educational institutions or organizations managing multiple developers.
