Simply Fortran
What Simply Fortran is
Simply Fortran is a desktop Fortran development environment for Windows and Linux. It combines a compiler, coding editor, and graphical debugger, with support for legacy code, derived-type autocompletion, module dependency management, procedure definitions, contextual help, and structural file outlines. The debugger includes breakpoints, variable inspection, and call-stack navigation. GNU Fortran is integrated, while Flang, Open Watcom, and Approximatrix WebFortran are also supported. The compiler supports OpenMP; BLAS and LAPACK are included, with coarray or MPI options described for Windows and Linux. Windows and GNU/Linux versions include Aplot 2D plotting, and Windows also includes AppGraphics. Git repositories and common source-control actions are available through a graphical interface, and the environment can communicate with language servers. Pricing starts at $149 a year, with a 30-day trial and no free plan.
