1 " LLVM coding guidelines conformance for VIM
4 " Maintainer: The LLVM Team, http://llvm.org
5 " WARNING: Read before you source in all these commands and macros! Some
6 " of them may change VIM behavior that you depend on.
8 " You can run VIM with these settings without changing your current setup with:
9 " $ vim -u /path/to/llvm/utils/vim/vimrc
14 " A tab produces a 2-space indentation
19 " Highlight trailing whitespace and lines longer than 80 columns.
20 highlight LongLine ctermbg=DarkYellow guibg=DarkYellow
21 highlight WhitespaceEOL ctermbg=DarkYellow guibg=DarkYellow
23 " Lines longer than 80 columns.
24 au BufWinEnter * let w:m0=matchadd('LongLine', '\%>80v.\+', -1)
26 " Whitespace at the end of a line. This little dance suppresses
27 " whitespace that has just been typed.
28 au BufWinEnter * let w:m1=matchadd('WhitespaceEOL', '\s\+$', -1)
29 au InsertEnter * call matchdelete(w:m1)
30 au InsertEnter * let w:m2=matchadd('WhitespaceEOL', '\s\+\%#\@<!$', -1)
31 au InsertLeave * call matchdelete(w:m2)
32 au InsertLeave * let w:m1=matchadd('WhitespaceEOL', '\s\+$', -1)
34 au BufRead,BufNewFile * syntax match LongLine /\%>80v.\+/
35 au InsertEnter * syntax match WhitespaceEOL /\s\+\%#\@<!$/
36 au InsertLeave * syntax match WhitespaceEOL /\s\+$/
39 " Enable filetype detection
43 " C/C++ programming helpers
46 autocmd FileType * set nocindent smartindent
47 autocmd FileType c,cpp set cindent
49 " Set a few indentation parameters. See the VIM help for cinoptions-values for
50 " details. These aren't absolute rules; they're just an approximation of
51 " common style in LLVM source.
52 set cinoptions=:0,g0,(0,Ws,l1
53 " Add and delete spaces in increments of `shiftwidth' for tabs
56 " Highlight syntax in programming languages
59 " LLVM Makefiles can have names such as Makefile.rules or TEST.nightly.Makefile,
60 " so it's important to categorize them as such.
62 au! BufRead,BufNewFile *Makefile* set filetype=make
65 " In Makefiles, don't expand tabs to spaces, since we need the actual tabs
66 autocmd FileType make set noexpandtab
68 " Useful macros for cleaning up code to conform to LLVM coding guidelines
70 " Delete trailing whitespace and tabs at the end of each line
71 command! DeleteTrailingWs :%s/\s\+$//
73 " Convert all tab characters to two spaces
74 command! Untab :%s/\t/ /g
76 " Enable syntax highlighting for LLVM files. To use, copy
77 " utils/vim/llvm.vim to ~/.vim/syntax .
79 au! BufRead,BufNewFile *.ll set filetype=llvm
82 " Enable syntax highlighting for tablegen files. To use, copy
83 " utils/vim/tablegen.vim to ~/.vim/syntax .
85 au! BufRead,BufNewFile *.td set filetype=tablegen
88 " Additional vim features to optionally uncomment.
