Vim features and plugins useful for D coding.

Installing Vundle

Many Vim plugins require a plugin manager for installation. Vundle is one such plugin manager.

To install Vundle see the Quick Start section on Vundle's site.

UltiSnips

UltiSnips is a Vim snippet plugin with D support. It makes it possible to complete tasks such as writing a loop, wrapping code in try/catch or adding an operator in a few keystrokes.

Installing UltiSnips:

  • Make sure you have a plugin manager such as Vundle installed.
  • See the Quick Start section at UltiSnips site.

DSnips

DSnips is a (greatly) improved version of UltiSnips D snippets. It covers almost all D features and its snippets are designed to work together (e.g. can be used within one another or in chains). See DSnips reference

Installing DSnips:

  • You need to have UltiSnips installed first.
  • git clone https://github.com/kiith-sa/DSnips.git
  • Copy the d.snippets file to UltiSnips user snippets directory. On Linux this should be ~/.vim/UltiSnips.

    If you don't know where the user snippets directory is, open a D file and type the :UltiSnipsEdit command (after UltiSnips is installed); this will open a user d.snippets file which you can replace by the DSnips version of d.snippets.

Dutyl

The Dutyl plugin integrates D tools such as DCD, DUB and DScanner to provide autocompletion, syntax checking, documentation search and more features.

Vebugger

The Vebugger plugin acts as a frontend for command line debuggers, and can be used to debug D programs with GDB. You'll need to use :VBGstartGDBForD to debug D programs.

Tagbar

It also possible to display a tagbar of all all declared functions, classes etc. Please follow the instructions of tagbar's Wiki.

Highlighting Phobos

The vim-dlang-phobos-highlighter plugin allows highlighting of Phobos (functions, templates and types) and user defined functions, along with version identifiers.

Neovim

With the rise of Neovim, deoplete-d can be used for auto-completion.

Errorformat

WIth this autocmd D will parse error messages from the compiler and the unit test assertions;

autocmd FileType d set efm=%*[^@]@%f\(%l\):\ %m,%f\(%l\\,%c\):\ %m,%f\(%l\):\ %m

Unit Testing

The following function runs unittests on the current file and displays coverage information as a split window bound to left of the source window;

function! DTest()
  let l:fn = substitute(expand('%:r'), '/', '-', 'g') . '.lst'
  call delete(l:fn)
  cexpr system('dmd -cov -unittest -main -run ' . expand('%'))
  if filereadable(l:fn)
     normal gg
     execute '13vsplit' l:fn
     normal gg
     set scrollbind
     normal ^Wl
     set scrollbind
  endif
endfunction

(note the ^W is a an actual CTRL-W, inserted with CTRL-V, CTRL-W)

autocmd FileType d nnoremap <f8> :call DTest()<cr>
