Indentation

[TomDeneire]

One possible improvement of the plugin would be to provide a Vim indentation file for MUMPS dotlevel indentation. I've tried to solve this by remapping in insert mode to a function that appends a line based on the previous one (and on what's under the cursor, ie do or quit), but didn't get it to work. Probably not even a good idea. Vim newbie here!

Hi David,

thought I'd get back to you on the idea of remapping , because it has been working out fine for me.

My ftdetect/mumps.vim contains the following:

"functions
function! Indent()
    let wordUnderCursor = expand("<cword>")
    let current_line = getline(".")
    let indent_level = split(current_line," ")
    let indent_begin = indent_level[0]
    if (wordUnderCursor == "d") || (wordUnderCursor == "q")
        if (wordUnderCursor == "d")
            if matchstr(indent_begin, ".") == "."
                let indent = " " . indent_begin . ". "
            else
                let indent = " . "
            endif
        endif
        if (wordUnderCursor == "q")
            if indent_begin[0] == "."
                let indent_minus_one = len(indent_begin)-2
                if indent_minus_one == -1
                    let indent = " "
                else
                    let indent = " " . indent_begin[0:indent_minus_one] . " "
                endif
            else
                let indent = " "
            endif
        endif
    else
        " to do: normal linebreak!
        if indent_begin[0] == "."
            let indent = " " . indent_begin . " "
        else
            let indent = " "
        endif
    endif
    call append(line("."), indent)
    let curpos=getcurpos()
    let curpos[1] += 1
    call setpos(".", curpos)
    call feedkeys("A")
endfunction

autocmd FileType mumps inoremap <buffer> <TAB> .
autocmd FileType mumps inoremap <buffer> <CR> <ESC>:call Indent()<CR>
autocmd FileType mumps inoremap <buffer> <c-r> <CR>

You'll see this is far from perfect. It doesn't account for a midline enter, i.e. a "normal" one, hence the last remapping. Also, I have no experience in Vimscript whatsoever and I was struggling with scoping.

But I still thought I'd send you this in case you find it useful, also because I've just replaced the Vimscript version with a Lua one, since I'm using Neovim anyway.

all the best,

T.

Thank you. I'll look at this when I get around to exploring this request.
