&quot; Credits:
&quot; o steve hacked this out of a random indent file in the Vim 6.1
&quot;   distribution that he no longer remembers...sh.vim?  Thanks!

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

setlocal indentexpr=GetMmaIndent()
setlocal indentkeys+=0[,0],0(,0)
setlocal nosi &quot;turn off smart indent so we don't over analyze } blocks

if exists(&quot;*GetMmaIndent&quot;)
    finish
endif

function GetMmaIndent()

    &quot; Hit the start of the file, use zero indent.
    if v:lnum == 0
        return 0
    endif

     &quot; Find a non-blank line above the current line.
    let lnum = prevnonblank(v:lnum - 1)

    &quot; use indenting as a base
    let ind = indent(v:lnum)
    let lnum = v:lnum

    &quot; if previous line has an unmatched bracket, or ( indent.
    &quot; doesn't do multiple parens/blocks/etc...

    &quot; also, indent only if this line if this line isn't starting a new
    &quot; block... TODO - fix this with indentkeys?
    if getline(v:lnum-1) =~ '\\\@&lt;!\%(\[[^\]]*\|([^)]*\|{[^}]*\)$' &amp;&amp; getline(v:lnum) !~ '\s\+[\[({]'
        let ind = ind+shiftwidth()
    endif

    &quot; if this line had unmatched closing block,
    &quot; indent to the matching opening block
    if getline(v:lnum) =~ '[^[]*]\s*$'
        &quot; move to the closing bracket
        call search(']','bW')
        &quot; and find it's partner's indent
        let ind = indent(searchpair('\[','',']','bWn'))
    &quot; same for ( blocks
    elseif getline(v:lnum) =~ '[^(]*)$'
        call search(')','bW')
        let ind = indent(searchpair('(','',')','bWn'))

    &quot; and finally, close { blocks if si ain't already set
    elseif getline(v:lnum) =~ '[^{]*}'
        call search('}','bW')
        let ind = indent(searchpair('{','','}','bWn'))
    endif

    return ind
endfunction
