vim smart-indenting for filetypes other than C

[s_siouris]

Hello to all (this is my first post)

I am currently learning C and a little bit of Fortran programming. I am mainly using vim and I have seen that smart-indenting is an excellent help for writing c programs, but cannot figure out how to emable this when writing fortran code. (even when I open a .f,... file and not starting from scratch)

Q1. I have read from the manuals that autocmd has to be enabled at compile time for the smart indenting of the different filetypes. I am using fedora core 3 and I am not sure if vim was compiled with autocmd or not. How do I check this?

Q2. If autocmd is enabled as default, then how do I import eg. fortran.vim indenting file to vim, so that it could smart indent fortran code

Thanks in advance

You need to find and edit the fortran.vim file. This is the file that tells vim what to do when it comes to color formatting (aka syntax highlighting) and indention.

Mine was located in:
/usr/share/vim/vim61/indent/

You can look at the c.vim for an example.

Thanks for the reply Thantos,

I do know that there is a file for each language with specific indenting settings and I have already lokked at these. My problem is how to load these to vim. Furthermore, from the vim help files, I read that autocmd has to be enabled during compilation in order for these files to work. Problem is that I don't know how to check if autocmd was enabled (and also on the level of feaures from the feature.h file)

Does it work when you use a c file?

edit: type "vim --version" and it will give you a list of the build options.

[s_siouris]

Thanks! :version shows that autocmd has been included (also in help->version, ...stupid of me)

as for c files, smart-indenting works. I don't need to do anyting because support for c is built in vim (as the c.vim file says).
When i load up a fortran file, highlighting works fine, but not the smart-indenting (if that helps...)

cheers for your time on this!

ok I didn't look at the c.vim before saying to use it as an example

if you have it look at perl.vim it has some code for indenting perl code.

[s_siouris]

ok, I did that, but I can't see anything that helps me

" Only load this indent file when no other was loaded.
if exists("b:did_indent")
  finish
endif
let b:did_indent = 1

this is at the start of each indent file, the problem is how to load a specific indent file...

EDIT: just saw your avatar! Al Pitrelli rocks!, heard of savatage, skolnick,....? savatage is one of my favourite bands,... but back to geeky stuff now...

[Thantos]

So you didn't notice the

setlocal indentexpr=GetPerlIndent()
setlocal indentkeys+=0=,0),0=or,0=and
if !b:indent_use_syntax
  setlocal indentkeys+=0=EO
endif

" Only define the function once.
if exists("*GetPerlIndent")
  finish
endif

function GetPerlIndent()

  " Get the line to be indented
  let cline = getline(v:lnum)

  " Indent POD markers to column 0
  if cline =~ '^\s*=\L\@!'
    return 0
  endif

  " Don't reindent coments on first column
  if cline =~ '^#.'
    return 0
  endif

etc

In the perl.vim file? fortran.vim is being loaded when you start vim if the fortran syntax highlighting is working like you said.

sorry but to be honest, that doesn't say much to me. I am just starting to learn how to program in c (been studying couple of months) the most complicated thing i've done is pointers to pointers (not done linked lists yet) and very little in fortran.
when I load a fortran file, (supposing that the indenting file is loaded) I expect for example that in a FOR loop, when I am at the end of the line where FOR is written, and press enter, the cursor will indent a bit more that the previous line, but it doesn't. This is ok in c programs. Autoindenting works ok, highlighting ok as well, but no smart-indent for filetypes other than c.

when you load up a file, do you get smart-indenting without doing anything? (eg such as in perl that you mentioned?)

[Thantos]

Well the perl one was already written. So to do what you want you'll have to modify the fortran.vim file to take care of those cases. Or find someone that already has done it.

[s_siouris]

ok I'll try to sort it out, although I do think that this smart-indenting example is pretty basic hence should have been the first thing to be impplemented in the fortran.vim indenting file.

thanks for your help
