  \u201cFortran module (free-form)\u201d or<\/li>\n
  \u201cFortran class (free-form)\u201d, respectively.
  \nFor normal Fortran programs choose the first.<\/li>\n<\/ul>\n<\/li>\n

  Issues and bugs<\/h1>\n
  \n
  EfSC build process does not recognize capital extensions, like \u201cF90\u201d as Fortran sources
  \n<\/strong> Many Fortran compilers, so as Gfortran, pre-process these files, and process pre-processor directives in your code. Unfortunately you cannot add these extensions to the extensions list in PREFERENCES > C\/C++ > FILE TYPES. EfSC is not case sensitive in this case and reject them as doubles. EfSC is very flexible. Maybe it is possible to setup the pre-processor in \u201cBuild Steps\u201d in C\/C++ BUILD > SETTINGS. But nothing simple.<\/li>\n
  Compiler and linker path<\/strong>
  \nEfSC expects Gfortran\u2019s executable in \/usr\/bin\/<\/span> for some reasons. To have it in the path is not sufficient. So you have to setup the compiler and linker path on every new project (see above) for every configuration (Debug, Release, etc.) which is annoying. I have not found any settings to set this Eclipse-wide.
  \nThis does not happen on GNU\/Linux for obvious reasons: Gfortran is in \/usr\/bin\/<\/span> on Linux. I have not tested it on Windows. Setting a symbolic link to \/usr\/bin\/<\/span> of gfortran as a workaround is not permitted on my Ventura with Homebrew even with sudo<\/span>.<\/li>\n<\/ul>\n
  What is missing<\/h1>\n
  In comparison to other Fortran IDEs, EfSC has unique features for parallel and remote computing. But if you just look for an IDE for local work EfSC lacks some useful features other IDEs provide:<\/p>\n
  \n
  Code auto-complete<\/li>\n
  Call tips for function and subroutine arguments<\/li>\n
  Automated element renaming<\/li>\n
  Auto-build (Makefile generation) for libraries<\/li>\n<\/ul>\n
  Target groups<\/h1>\n
  Students<\/h2>\n
  To setup the compiler path on every new project is annoying, especially for students in a Fortran course who create a lot of small projects frequently.<\/p>\n
  But they get a convenient auto-build environment with a graphical debugger. This is useful for bigger projects with external modules.<\/p>\n
  If students just have to deal with small projects of just one source file, a graphical debugger and auto-build or Git-integrity is not important. To avoid the use of the command-line (many people are afraid of) and normal editors I recommend the lightweight IDE Geany<\/em>, TextMate<\/em> or Visual Studio Code<\/em> for this target group.<\/p>\n
  Geany<\/strong><\/a> runs for one-file<\/em> Fortran projects almost out-of-the box. Just switch from tab to spaces indentation in Edit > Preferences > Editor > Indentation > Type > Spaces.<\/p>\n
  Pretty much the same with TextMate<\/strong><\/a> with its preinstalled Fortran bundle. There are no adjustments needed.<\/p>\n
  Updated 2023-10-03<\/em>: But I recommend Visual Studio Code<\/strong><\/a> for this purpose. It is the most convenient and works in Windows and GNU\/Linux as well. And it can also provide visual debugging<\/a>. You just need to add the extensions Modern Fortran<\/em>,\u00a0GDB Debugger \u2013 Beyond<\/em> and Code Runner<\/em>. A single Fortran file can be compiled, linked and executed by pressing a single button and the result is displayed in the inbuilt terminal. For debugging the settings.json<\/span> of Code Runner at Executor Map<\/span> need to be extended with the compiler option -g<\/span> at all Fortran commands, e.g.: \u201cfortran\u201d: \u201ccd $dir && gfortran -g<\/span> $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt\u201d,<\/span><\/p>\n
  But all mentioned solutions are not the first choice for multiple file<\/em> projects.<\/p>\n
  If these students go for Eclipse anyway I recommend to turn on the auto-build on save at PROJECT > PROPERTIES > Fortran Build > Build on resource save (Auto build).<\/p>\n
  The pre-processing bug will not have an impact on these users.<\/p>\n
  If students work on medium projects beyond beginner Fortran courses the situation is different. Therefore EfSC can be useful.<\/p>\n
  Hobbyists, researcher, postgraduates<\/h2>\n
  For medium scale projects the compiler path inconvenience is not a big deal. The auto-build and debugger features overcompensate this issue. Especially if they have to deal with HPC and can make use of the parallel-computing-capabilities of EfSC or the refactoring tools.<\/p>\n
  Unfortunately convenient features as code-autocompletion, automated element renaming, call tips for function and subroutine arguments, etc. are not included. Furthermore the auto-build feature cannot build libraries. You have to write them on your own or use external tools.<\/p>\n
  The preprocessing bug could have an impact.<\/p>\n
  But if they could afford 140,- USD they should give SimplyFortran<\/a> a try. 30 day trial is available free of charge.<\/p>\n
  Professionals<\/h2>\n
  I guess they will use a commercial IDE and compiler and\/or use a different platform \ud83d\ude09 But EfSC has unique features for them. The synchronized projects if they work on code for supercomputers or clusters. And also the Parallel Tools Platform with parallel debugger, tools for MPI\/OpenMP, etc.<\/p>\n
  Conclusion<\/h1>\n
  Eclipse for Scientific Computing<\/strong> is the best non-commercial Fortran IDE for macOS. It is cross-plattform, so you can use it on all systems you are on, not only macOS.<\/p>\n
  For High Performance Computing (HPC) the synchronized projects make it unique, even on other platforms. Also an enormous plus is the Parallel Tools Platform with its parallel debugger and MPI\/OpenMP integration, if you need this. But where there is light there is shadow also.<\/p>\n
  For a student<\/strong> who just has to handle a lot but small one file projects in a Fortran course, Eclipse is maybe to much hassle due to\u00a0 project configuration.<\/p>\n
  For medium scale developer<\/strong> outside the HPC some convenient features other IDEs provide are missing. But it is still a good IDE for macOS for this target group. On other platforms Code::Blocks for Fortran <\/em>is maybe a better alternative. But we are here on a Mac. Maybe a commercial IDE fits the whole, like SimplyFortran<\/em>.<\/p>\n
  For HPC-developer<\/strong> Eclipse for Scientific Computing<\/em> is for them. The parallel tools and remote development capabilities to let run your code on a remote supercomputer supports them. But I am not such a developer.<\/p>\n
