" LLVM coding guidelines conformance for VIM
"
" Maintainer: The LLVM Team, http://llvm.org
" WARNING: Read before you source in all these commands and macros! Some
" of them may change VIM behavior that you depend on.
"
" You can run VIM with these settings without changing your current setup with:
" $ vim -u /path/to/llvm/utils/vim/vimrc
" It's VIM, not VI
set nocompatible
" Wrap text at 80 cols
set textwidth=80
" A tab produces a 2-space indentation
set softtabstop=2
set shiftwidth=2
set expandtab
" Highlight trailing whitespace
highlight WhitespaceEOL ctermbg=DarkYellow guibg=DarkYellow
match WhitespaceEOL /\s\+$/
" Enable filetype detection
filetype on
" Optional
" C/C++ programming helpers
augroup csrc
au!
autocmd FileType * set nocindent smartindent
autocmd FileType c,cpp set cindent
augroup END
" Set a few indentation parameters. See the VIM help for cinoptions-values for
" details. These aren't absolute rules; they're just an approximation of
" common style in LLVM source.
set cinoptions=:0,g0,(0,Ws
" Add and delete spaces in increments of `shiftwidth' for tabs
set smarttab
" Highlight syntax in programming languages
syntax on
" LLVM Makefiles can have names such as Makefile.rules or TEST.nightly.Makefile,
" so it's important to categorize them as such.
augroup filetype
au! BufRead,BufNewFile *Makefile* set filetype=make
augroup END
" In Makefiles, don't expand tabs to spaces, since we need the actual tabs
autocmd FileType make set noexpandtab
" Useful macros for cleaning up code to conform to LLVM coding guidelines
" Delete trailing whitespace and tabs at the end of each line
command! DeleteTrailingWs :%s/\s\+$//
" Convert all tab characters to two spaces
command! Untab :%s/\t/ /g
