Vim highlighting weird parts of FORTRAN
If you search
:help fortran, you'll get a list of options that you can set.
These are the fortran options I set in my own .vimrc file. (I don't work with fixed-format code though) I know there are one or two fortran specific scripts that are available online, but I don't use them.
let fortran_free_source=1 let fortran_have_tabs=1 let fortran_more_precise=1 let fortran_do_enddo=1
Vim was using fixed-format/punchcard when I created a new .f90 file. In order to differentiate it, I found this. I copied it to my ~/.vim/syntax/ directory and added the following lines to my .vimrc (also specified at following link)
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>
Allowing me to bind Shift-F to switch formats, and Ctrl-F to auto detect.
You can install the Fortran F90/95 indentation rules script in
~/.vim/after/indent, and it should fix the index errors.

I am using VIM theme molokai, if that makes any difference.
I have been learning FORTRAN lately and when I write a FORTRAN program using VIM, I have weird coloring depending on my whitespace.
For instance, if I tab things over as is (no indenting) I have this purple highlight on only a portion of the word (sometimes it isn't there, notice the PRINTs and READs).
If I tab it over it looks normal:
I am new to VIM (not to mention FORTRAN) so I am not sure what's happening, I don't mind tabbing over all the time but I think it looks a little ridiculous if the whole program is wasting that column of white space.
