Posted to the Perl QA list, but I figure some of you might want this.

For some strange reason, many folks seems to hate updating test plans. I don't know why this seems like so much work, given what a tiny task it is compared to the bulk of the code, but basically, here's how it works. You change this:

To this:

And when you're done, you change it back and update the test count. Some people think this is too much work, so based upon some vim code chromatic had, I wrote the following plugin. This could use a lot of work, but you might want to save this as ~/.vim/plugin/ToggleTestPlan.vim.

    if exists( "toggle_test_plan" )
        finish
    endif
    let toggle_test_plan = 1

    map ,tp :call ToggleTestPlan()<cr>

    function ToggleTestPlan()
        call SavePosition()
        let curr_line = 1
        while curr_line <= line("$")
            if match(getline(curr_line), 'More\s*tests') > -1
                %s/More tests =>/More 'no_plan'; # tests =>/
                call RestorePosition()
            elseif match(getline(curr_line), 'More\s*''no_plan') > -1
                %s/More 'no_plan';\s*# /More /
            endif
            let curr_line = curr_line + 1
        endwhile
    endfunction

    function SavePosition()
        let s:curLine = winline()
        let s:curColumn = wincol()
    endfunction

    function RestorePosition()
        exe s:curLine
        exe "normal! ".s:curColumn."|"
    endfunction

Basically, that maps ,tp to ToggleTestPlan() and toggles your test plan back and forth. If you switch to 'no_plan', it leaves your cursor where it is. If you switch to tests => $num_tests, it puts your cursor on the right line to change the test number. I could add more, but since I'm such a vim scripting newbie, I figure others are better placed to fix other issues. For example, the stuff for saving and restoring position were originally called like this (ganked from another plugin):

And defined like this:

  " SaveCursorPosition
  function! <SID>SaveCursorPosition()
    let s:curLine = winline()
    let s:curColumn = wincol()
  endfunction

Why were they defined like that? Who knows? Any explanations and improvements appreciated.

Update: I now know why they were defined like that. After I get home tonight, I'll do some more work and have a much better version of this code available.
