Can someone help me make this work. This is in my filetype.vim.
au BufNewFile,BufRead *.tex :map <F5> :!latex "%" && yap fnamemodify
("%", ":r").dvi<CR>
That should be on one line. What I want to do is, when I load a *.tex
file in Vim, I want Vim to automatically map a compile & view command
to the <F5> key.
The view command needs a .dvi extension. The program is receiving
"fnamemodify( . . ." as the file name. I need fnamemodify() to be
evaluated before it's passed to the shell and it's just not happening.
Thanks!

Just as you used "%" to get the current file name for latex, you can use
"%:r.dvi" to get the name of the dvi file for yap.
au BufNewFile,BufRead *.tex :map <F5> :!latex "%" && yap "%:r.dvi"<CR>
To use fnamemodify() to construct the file name, you'd have to use
:execute to evaluate the entire command and expand() to evaluate "%",
something like this (all on one line):
au BufNewFile,BufRead *.tex :map <F5> :exe '!latex "%" && yap' fnamemodify(expand("%"), ":r").'.dvi'<CR>

Thanks Gary! Those file name expansion characters have been confusing
me lately, because they don't seem to work all the time. For example,
if I do a ":echo %" (without the quotes) it gives me an "Invalid
expression: %" error. I thought I could print the file name with
that. I mean, I know there's Ctrl-g, but sometimes I like to test
things with print statements. I don't know, but thanks for the reply!
