If the form of the source code depends upon the file extension, then it is
most convenient to set fortran_free_source in a ftplugin file. For more
information on ftplugin files, see |ftplugin|. For example, if all your
fortran files with an .f90 extension are written in free source form and the
rest in fixed source form, add the following code to your ftplugin file >
let s:extfname = expand("%:e")
if s:extfname ==? "f90"
let fortran_free_source=1
unlet! fortran_fixed_source
else
let fortran_fixed_source=1
unlet! fortran_free_source
endif
Note that this will work only if the "filetype plugin indent on" command
precedes the "syntax on" command in your .vimrc file.
If the form of the source code depends, in a non-standard way, upon the file
extension, then it is most convenient to set fortran_free_source in a ftplugin
file. For more information on ftplugin files, see |ftplugin|. Note that this
will work only if the "filetype plugin indent on" command precedes the "syntax
on" command in your .vimrc file.
When you edit an existing fortran file, the syntax script will assume free
source form if the fortran_free_source variable has been set, and assumes
fixed source form if the fortran_fixed_source variable has been set. If
neither of these variables have been set, the syntax script attempts to
determine which source form has been used by examining the first five columns
of the first 250 lines of your file. If no signs of free source form are
detected, then the file is assumed to be in fixed source form. The algorithm
should work in the vast majority of cases. In some cases, such as a file that
begins with 250 or more full-line comments, the script may incorrectly decide
that the fortran code is in fixed form. If that happens, just add a
non-comment statement beginning anywhere in the first five columns of the
first twenty five lines, save (:w) and then reload (:e!) the file.
determine which source form has been used by examining the file extension
using conventions common to the ifort, gfortran, Cray, NAG, and PathScale
compilers (.f, .for, .f77 for fixed-source, .f90, .f95, .f03, .f08 for
free-source). If none of this works, then the script examines the first five
columns of the first 500 lines of your file. If no signs of free source form
are detected, then the file is assumed to be in fixed source form. The
algorithm should work in the vast majority of cases. In some cases, such as a
