  • Code::Blocks IDE for Fortran An IDE for Fortran 2003 and 2008.
  • Emacs – V 23.x and later come with f90-mode supporting Fortran 2003.
  • gedit – free-format Fortran 95
  • jed – Programmer’s editor that supports fixed-format Fortran 77 and free-format Fortran 2003 modes with syntax highlighting and smart indentation.
  • Vim – Supports Fortran syntax up to Fortran 95, but see below.
  • NEdit – GUI editor with some Fortran support. It used to be a good choice, but is rather obsolete compared to gedit.
  • Eclipse with Photran – For the IDE users.
  • Geany: GUI editor with support for many languages as well as Fortran; see below.
  • Sublime Text 2 – A beautiful text editor (paid but no enforced time limit for free use) that supports Fortran syntax via Textmate bundle.
  • Kate: – Has syntax highlighting and indentation for Fortran.
  • Zeus: – A (shareware) programmer’s editor for Windows with Fortran syntax highlighting and code navigation.
  • Photran is an IDE and refactoring tool for Fortran based on Eclipse. Photran supports Fortran 77-2008 and is actively maintained with annual releases. It includes 39 refactorings (including Rename, Extract Procedure, and loop transformations), as well as the many IDE features.
  • Visual Studio Code is an lightweight open source alternative to Visual Studio. It can be expanded by plugins (see below).

  • Code::Blocks IDE for Fortran http://cbfortran.sourceforge.net/: Recommended! Originally developed for C++, this advanced IDE has many features of eclipse and supports most features of Fortran 2003 and 2008. The environment is quite user friendly and easy to use. It is one of the few true IDEs for Fortran. I think the support of the Fortran community will help this IDE to become a very powerful general purpose and fast Fortran programming tool.

  • Jedit - written in Java - when opening more than one file this has no tabs but a drop-down list at the top, which I find less convenient. But it has good Fortran90 aware syntax highlighting (I had to make a small change to the configuration file to prevent every line starting with C being treated as a comment, but that was not difficult). But the print system is a Java-special, not using the regular Windows print menu, so you can’t alter your printer defaults, e.g. to print 2 pages per sheet of paper. This is an annoyance.

  • Gedit - there is a windows binary to download which worked with no trouble, but there is no manual and no help (missing file). The syntax highlighting did work for Fortran90, but it did not understand the .f90 or .f95 file extension, and had to be set each time, which was very tedious. I could not find the relevant file on the website, nor when I untarred a regular gedit distribution. Looking at the help on a Linux box there did not seem to be a way of associating file extensions with language highlighting.

  • Notepad++ - has tabbed browsing, and uses regular Windows printing, but the syntax highlighting was set for Fortran77, and was really not useful. After being annoyed by it for some time, I found it best to disable the highlighting entirely. In principle one could define one’s own Fortran90 syntax file, but I couldn’t be bothered to do this. Apart from this it’s a fairly good editor.

  • Notetab light - the free version of a commercial editor notetab. This is another adequate editor: regular Windows printing, no tabbed file opening, no syntax highlighting. It seems to have no particular features that at least one of the others has.

  • Geany(http://www.geany.org/): This is a free open source editor with many capabilities which also supports programming in Fortran. There are several plugins to deal with project management, debugging etc. The editor lets you for extensive customization for a programming language and even adding new one! It is available for both Windows and Linux.

  • Simply Fortran(http://simplyfortran.com/): lightweight IDE for MS Windows and compatible operating systems. Made with GNU Fortran in mind, but configurable with most compilers, it comes with an intergrated development environment, a graphical debugger, and a collection of other development accessories. In early stages of development as of now, has some bugs, but the author’s working on them.

  • Programmer’s Notepad - A general source code editor for MS Windows. It can be configured to build Fortran files with arbitrary command lines, or to invoke make in a particular directory. Like many editors, it is C-centric, but the Fortran support is adequate.

  • Absoft Pro Fortran - A IDE developed by Absoft specially for Fortran. http://www.absoft.com/

  • FTranProjectBuilder - Fortran specific development environment for the Mac with built-in source code editor, makefile generator, and lab notebook. It’s Mac-native, self configuring and works with any Fortran compiler, including mpiXX for parallel computations. Fortran 2003+ features include variable and type bound procedure auto-completions. http://www.NocturnalAviationSoftware.com

  • UltraEdit - General source code editor for multiple languages with syntax checking. http://www.ultraedit.com. Runs on Mac, Linux and Windows 32 and 64 bit. There is a companion product called UltraCompare which allows one to compare files. Syntax checking is acheived through what the vendor calls word files. The vendor has a fairly good size library of wordfiles, but you can create your own if you wish. The Product also allows the developer to organize their work in a project fashion. Support for ftp,sftp, etc. Also allows column editing mode. I have been developing for decades and find this tool to be the best on the market when it comes to editors. Not a free product.

  • Visual Studio Code - To use VSC for Fortran on Linux i recomend installing the following plugins: Fortran Language Server, C/C++ for Visual Studio Code, Modern Fortran language support for VSCode, Fortran IntelliSense and Fortran Breakpoint Support.

An enhanced Vim syntax file that includes Fortran 2003 keywords is available here:

The following can be added to $HOME/.vimrc. It maps <shift>-F to toggle between fixed and free format Fortran source. In case it is hit by mistake, <ctrl>-F is mapped to re-detect the syntax.

findent indents fortran source, both fixed and free format. Conversion from fixed to free is also possible. Available for Linux and Windows. Plugins for vim and gedit are contained in the tarball at findent.sourceforge.net

Free Fortran Compilers

There are a number of free Fortran 77 and 90 compilers available on thenet.The one I have been using in my Fortran courses at York isGNU, which implements Fortran 77 and adds several Fortran 90 features. Thanks to Prof. Clive Page (Dept of Physics & Astronomy, University of Leicester, UK)for providing the compiler and for valuable advice on Fortran in general.

You can download the 1999 version of this compiler (version 2.95 of gcc) along with the SLATEC library (Version 4.1, July 1993), from this page. Thepackage should run under all versions ofWindows.All the needed files are packed in one zipped file(Fort99.zip) of about 6MB.

(If for some reason you need the older DOS/EMX version,which does not include a library and does not run under Windows XP, then youcan download it from my old page.)

DOWNLOAD

  • Create the directory F
    The new folder must be immediately under the root of your hard disk. You can do this by double-clicking MyComputer, then double-clicking your hard drive (usually C:), and then selecting New Folder from the File menu and calling the folder F.
  • Download the file Fort99.zip (5,820,239 bytes).
    You can do this by right-clicking the mouse on the above link, and choosing Save Target As.... In the Save As window that appears, locate the F folder, and save the file in it.
  • Unzip the downloaded file into F.
    Yon can do this by locating the file (starting from MyComputer) and simply double-clicking it to launch the zip/unzip program. Make sure to specify that all files should be extracted immediately under the F folder.
    Note: If the unzip program does not give you the option to specify the extraction location, let it extract the content to anywhere and then move the extracted folders (using cut and paste) to F. When done, you should see the four folders G77, SLATEC, MINE, and YORK appearing in F.
GnuThat's it! You use the compiler through CLI, the command-line interface (akaterminal, command prompt, or DOS) after setting two environmentvariables, PATH and LIBRARY_PATH, as shown below.

USAGE

You store your programs in the

FYork directory, compile themusing: f2exe, and create library object files using f2lib.Here is a very short program to test the compiler and the configuration: Use any editor to create this program (simply copy and paste) and save it as a text file in the FYork directory under the name test.for

. Youcan, of course, use any editor you like as long as you can save the filein text format and with the extension you want. Notepad, for example, uses text but insists on using the

txt extension (unless you override by double-quoting) while MS-Word insists on its propriety format (unless you explicitly override). I highly recommend using the

Visual Fortran Free Download

Crimsoneditor, which can be downloaded from the on-line Lab-1 (see below).

To compile your program, start a CLI session (by launching the command promptprogram, usually in the Accessories group) and issue these two commands:These set the environment so that your computer would know where the compilerand its libraries are located.
Note: these two commands must be issued every time you start a CLI session. Youcan optionally automate this step by adding these two variables to the system-wideenvironment using the Control Panel.
You can now compile and run your program by typing:If the first command returned an error then the directory was not created (ornamed) correctly. If the second command was not recognized, or complained that a library is missing, then the environmentvariables were not set correctly (you can issue the set command without any arguments to inspect all environment variables).

More information on using the compiler can be found in theon-line Labs at theFortran@York site.

LANGUAGE

The FG77doc directory has a detailed reference to the language, which is largly ANSI Fortran-77but with some Fortran-90 features added (see below).

The above Fortran@York sitecontains a quick reference guide, lab, and SLATEC usage examples.If you are already familiar with Fortran then the following points may beall you need to know about this compiler:

  1. Control Structures
    You can use either the old (goto-based) or the new (structured) control flow (or mix them in the same program). Support of the 'ugly goto' is meant for existing code only, and any new development should avoid it.
  2. Style
    You can write your source using either the old style code (column 7) or the newer free-form.
  3. Compilation Command
    The above f2exe command is just a batch file that invokes g77, the 'real' compilation command. The command: directs the compiler to compile the file prog.for and stores the output in the file prog.exe. The -ffree-form switch indicates free-form style (remove it if you are using the old style).
  4. Comments
    In free-form style, use ! for both full-line and in-line comments. In the old style, use a 'C' in column-1.
  5. Statement Continuation
    In free-form style, you can continue a statement on the next line by ending it with an ampersand '&'. In the old style, put a character in column-6.
  6. Path Separator
    When referring to files (e.g. in the file=' ' parameter of the OPEN statement) use a forward slash '/' or two consecutive backslashes ' rather than a backslash to delimit directories. This is because the backslash ' denotes an escape sequence in strings.
  7. I/O Unit Numbers
    Not all unit numbers are allowed in the OPEN statement. In particular, unit 5 is 'pre-connected' to the keyboard. Units 10 through 99 seem to work well with disk files.
  8. Fortran-90 Features
    These include: Automatic arrays in subprograms, zero length strings, character constants may be enclosed in double quotes (') as well as single quotes, cycle and exit, the DOUBLE COMPLEX type, DO WHILE, the END decoration, KIND, IMPLICIT NONE, INCLUDE statements, list-directed and namelist I/O on internal files, binary, octal, and hex constants, `O' and `Z' edit descriptors, NAMELIST, OPEN specifiers STATUS='REPLACE', the FILE= specifier may be omitted in an OPEN statement if STATUS='SCRATCH' is supplied, relational operators <, <=, , /=, > and >= may be used instead of .LT., .LE., .EQ., .NE., .GT. and .GE. respectively, SELECT CASE (but not for character types).
  9. Separate Compilation of Subprograms
    Your main program is recognized by the program statement, as in the Convert program above. The subprograms (functions and subroutines) can be included in the same file as the main program (in which case you can compile everything in one shot) or can be stored in separate file(s). It is recommended that you store general reusable subprograms in separate files so that you can reuse them (without recompiling them) in future projects. To compile a file that contains only subprograms (no program statement), use the f2lib command, which generates object files, one per sub, in the mine directory, e.g. will compile (without linking) the subprogram in util.for and store the output (an object file) in the file util.o. f2lib is just a batch file that invokes the g77 command with the -c (compile-only) switch, viz.A program that uses pre-compiled object files can be compiled (and linked to them) by simply referring to them in the compilation command: The above command searches all object files in mine to resolve any missing reference in prog.for.
  10. Separate Compilation of Subprograms, automated
    The supplied f2exe and f2lib batch files take care of separate compilation and delayed linking with object files and with the SLATEC subprograms. You don't have to directly issue the g77 command unless you use the old columnar style or you want to change one of the switches or directories.
  11. Assembly Listing
    The -S (capital S) switch allows you to see a listing of the generated assembly code.
