If a coder is piping a source file that is in TEXT file format to a processor and is WILLING to provide a compiler option (e.g., -ffree-form) or a marker, then the file extension should NOT matter. See an example of perceived file types on Windows: > most compilers support this in various implementation-dependent ways. f90?Įmail: firstname at firstnamelastname dot com Is it really such an awful thing to type. This in various implementation-dependent ways. Marker in a source file - as others have said, most compilers support I will also note that not all platforms use the "extension"Ĭonvention of filenames to designate file type.Īs I wrote in the post, it's too bad that we didn't think about this 30 The standard makes a point of NOT specifying implementation details of Mucking about with file types will just introduce headaches.Īs for putting something like this in the standard - not gonna happen.

Intel Fortran on Windows does NOT "call the preprocessor when provided a file with an extension in upper case." > when provided a file with an extension in upper case.

Then a few others might start following it also leading to a new convention eventually!!

f90 has taken hold for free-form source code. Separately, file extensions can be viewed as a convention followed by coders.

f for their fixed-form code are not going to take at all kindly to "compilers can have switch to supprot old codes and previous libraries use the old convention" and rightly so, the "cost of change" with any such thing will never add up to any benefit in any budget controller's mind.

As you write, the standard does not cover any such aspect and to me, it makes to keep it that way.īesides the existing users who have long been using. I think you will find little support for any of this in terms of the Fortran standard. > old codes and previous libraries use the old convention. Or you may propose a new extension to be used for Modern fortran or free-form source code. Old codes and previous libraries use the old convention. for both are used for fixed-form code, but Fortran 2018 standard can propose this and compilers can have switch to supprot It does not have a year attached to the extension.
#Fortran read last line from file free
f90 as free source format for all new generation of Fortran from 1990 onward, but why not to mit the year attached to extension to have a universal file extension. The good suggestion by Steve Lionel is to stick with. It is known that the Fortran standard is quiet about file on disk for source code. This may seem an odd and duplicate question, but having a standard for fortran source file extensions can help to have a model.
