I’ve made an application for evaluating output of a number of lines i JavaScript (or any other interpreted language) in Vim.
This is possible in Vim out of the box. Select a number of lines in visual
mode, enter command mode. This will focus selected lines as such:
:'<, '>. Now add :w !node (or
python etc.) and the output will be displayed.
My application make something similar. If I make a visual selection and
press <leader>i the output is displayed in a floating
window.
function! GetResult()
let result_cmd = system("node ~/Documents/display-message/scratch-output")
let output = "\n\n" . "==> " . result_cmd
exec 'call system("echo \"" .
\ expand(output) . "\" >> ~/Documents/display-message/scratch-output")'
endfunction
vnoremap <leader>i
:w! ~/Documents/dev/display-message/scratch-output<CR>
:call GetResult()<CR>
:!~/Documents/dev/display-message/build/msg<CR>
