Interactive console program in which to edit, compile, and run Fortran code, tested on Windows and Linux.
Compile with gfortran -o fedit.exe buffer.f90 xbuffer_code.f90
Sample session:
c:\fortran\test>fedit.exe
> print*,2**5;
32
> del
> imp
> integer :: i
> do i=1,4
> print*,i,i**2
> end do
> list
1: implicit none
2: integer :: i
3: do i=1,4
4: print*,i,i**2
5: end do
> run
1 1
2 4
3 9
4 16
> q
STOP done -- code saved in temp.f90
Entering "help" or "h" gives these directions:
enter a line of Fortran code. Otherwise, ...
quit or q to quit
run or r to compile and run executable
a line of code terminated by ; causes the program to be compiled and run
runold or ro to run executable again without recompiling
compile to compile without running executable
list or l for a program listing with line numbers
barelist or bl for a program listing without line numbers
del to delete all code; del i to delete line i ; del i j to delete lines i to j
line n <code> to replace the current line n with <code>
insert n <code> to move lines n on down by 1 and put <code> on line n
imp is expanded to implicit none
fedit.exe foo.f90 pulls in code from foo.f90. Otherwise the program starts blank. In most cases
an end is supplied automatically and need not be supplied by the user.
