vim-qalc

Simple integration with qalc for vim, to make calculations easier

Installation

Use your favourite plugin manager. For example with Vundle.vim:

Plugin 'tim-clifford/vim-qalc'

Dependencies

• libqalculate

Optional:

• skywind3000/asyncrun.vim to enable evaluating an expression into a quickfix window

Usage

You can evaluate expressions in a few ways. Here are the default mappings (disabled with let g:qalc_mappings = 0). Note that the terminal and quickfix options only work with vim (not neovim) at the moment.

" Run into a quickfix window (requires AsyncRun)
vnoremap <leader>xq    :call qalc#ToQuickfix()<CR>
nnoremap <leader>xq viW:call qalc#ToQuickfix()<CR>

" Evaluate and put it in the active register
vnoremap <leader>xr    :call qalc#ToRegister(v:register)<CR>
nnoremap <leader>xr viW:call qalc#ToRegister(v:register)<CR>

" Evaluate and overwrite
vnoremap <leader>x<leader>    :call qalc#Substitute()<CR>
nnoremap <leader>x<leader> viW:call qalc#Substitute()<CR>

" Evaluate and put it in the " register
vnoremap <leader>xx      :call qalc#ToRegister(v:register)<CR>
nnoremap <leader>xx viW"":call qalc#ToRegister(v:register)<CR>

" Open qalc in a terminal window
noremap <leader>xt :term ++close qalc<CR>
