vim for FORTRAN

This page contains useful configuration of vim for FORTRAN.

I summarize several useful configurations:

• style of source file (the default is fixed style):

:let fortran_free_source=1
:let fortran_fixed_source=1
add them prior to the :syntax on command

if you want to switch between free style and fixed style, add the following lines:

nmap <S-F> :set syntax=fortran<CR>:let b:fortran_fixed_source=!b:fortran_fixed_source<CR>:set syntax=text<CR>:set syntax=fortran<CR>
nmap <C-F> :filetype detect<CR>

• enable Tabs in FORTRAN (otherwise they are marked as ugly red blocks):

:let fortran_have_tabs=1

• code folding:

" :za toggle code folding
" :zr (zR) open all
" :zm (zM) close all
" :zc close
" :zo open
set foldmethod=indent
set foldnestmax=10
set nofoldenable " no fold by default
set foldlevel=1   " some value I don't know...
" code folding for fortran
:let fortran_fold=1
:let fortran_fold_conditionals=1
:let fortran_fold_multilinecomments=1

• an enhanced vim script for FORTRAN 2003 keywords, can be found here.

• block comments

this plugin supports block comments for FORTRAN and others.
