Vimでperllocal.podを折り畳んで表示するPerlVim

perllocal.podが見難く編集し難いので、vimで開いた時に自動的にfoldingされるようにしました。

結果↓のように見れるようになります。編集も楽チン。

+-- 22 行:=head2 Mon Feb  4 11:45:23 2013: C<Module> L<App::cpanminus|App::cpanminus>----------------------------------------
+-- 22 行:=head2 Mon Feb  4 12:06:30 2013: C<Module> L<App::cpanoutdated|App::cpanoutdated>----------------------------------
+-- 22 行:=head2 Mon Feb  4 12:12:45 2013: C<Module> L<App::pmuninstall|App::pmuninstall>------------------------------------

~/.vimrcに以下のコードを追加すると動くと思います。=head2~=backをひとまとめにしているだけです。

function! s:fold_perllocal()
  function! l:foldexpr(lnum)
    if getline(v:lnum) =~ '^=head2'
       return '1'
    elseif getline(v:lnum - 1) =~ '^=back'
       return '<1'
    endif
    return '='
  endfunction
  setlocal foldmethod=expr foldexpr=l:foldexpr(v:lnum)
endfunction
autocmd BufRead perllocal.pod call s:fold_perllocal()

ちなみに例で挙げた3行は普通にperldocで見るとこんな感じです。

Mon Feb  4 11:45:23 2013: "Module" App::cpanminus
  *   "installed into: ./local/lib/perl5"

  *   "LINKTYPE: dynamic"

  *   "VERSION: 1.5021"

  *   "EXE_FILES: bin/cpanm"

Mon Feb  4 12:06:30 2013: "Module" App::cpanoutdated
  *   "installed into: ./local/lib/perl5"

  *   "LINKTYPE: dynamic"

  *   "VERSION: 0.24"

  *   "EXE_FILES: bin/cpan-outdated"

Tue Mon Feb  4 12:12:45 2013: "Module" App::pmuninstall
  *   "installed into: ./local/lib/perl5"

  *   "LINKTYPE: dynamic"

  *   "VERSION: 0.29"

  *   "EXE_FILES: bin/pm-uninstall"

折り畳まれてる方が断然見やすいですよね。

更にperldoc -mでソースを見るともう何が何やら。folding偉大です。
