It looks like the rst filetype has some custom indentation rules which
add this indentation. This works by setting the indentexpr
setting to GetRSTIndent
in /usr/share/vim/vim80/indent/rst.vim
.
To completely disable the rst indentation you can use something like:
augroup ftype_rst
autocmd!
autocmd Filetype rst setlocal indentexpr=
augroup end
This will disable all indent rules, which may not be what you want. To disable just these rules you can override the GetRSTIndent()
function in ~/.vim/after/indent/rst.vim
(I've commented out the five lines that add indentation for lists):
let s:itemization_pattern = '^\s*[-*+]\s'
let s:enumeration_pattern = '^\s*\%(\d\+\|#\)\.\s\+'
function! GetRSTIndent()
let lnum = prevnonblank(v:lnum - 1)
if lnum == 0
return 0
endif
let ind = indent(lnum)
let line = getline(lnum)
" if line =~ s:itemization_pattern
" let ind += 2
" elseif line =~ s:enumeration_pattern
" let ind += matchend(line, s:enumeration_pattern)
" endif
let line = getline(v:lnum - 1)
" Indent :FIELD: lines. Don’t match if there is no text after the field or
" if the text ends with a sent-ender.
if line =~ '^:.\+:\s\{-1,\}\S.\+[^.!?:]$'
return matchend(line, '^:.\{-1,}:\s\+')
endif
if line =~ '^\s*$'
execute lnum
call search('^\s*\%([-*+]\s\|\%(\d\+\|#\)\.\s\|\.\.\|$\)', 'bW')
let line = getline('.')
if line =~ s:itemization_pattern
let ind -= 2
elseif line =~ s:enumeration_pattern
let ind -= matchend(line, s:enumeration_pattern)
elseif line =~ '^\s*\.\.'
let ind -= 3
endif
endif
return ind
endfunction
You can also look at tweaking the s:enumeration_pattern
regexp. You didn't really mention which cases fail for you, so I can't really help you there.
