In this article, let’s explore the different ways to run our code, with and without plugins.

We are going to

  • Use the built-in compiler and ftplugin features to have a consistent way to build or run our code for different programming languages.
  • Configure Lua-based code runner plugins to run our code.
  • Explore plugins to run our code interactively and partially.
  • Use terminal-integration plugins to run our code.
  • Explore language-specific and test plugins.

Compiler and File Type Plugins

In this article, we walked through how to run, debug and monitor a Python application using different key mappings.

E.g. to run a Python application, we use the following mapping.

nnoremap <leader>rr  ":update<CR>:exec '!python3' shellescape(@%, 1)<CR>

For debugging, we use the built-in terminal and pdb.

nnoremap <leader>rd :update<CR>:sp term://python3 -m pdb %<CR>

To monitor the application, we can use nodemon.

nnoremap <leader>rn :update<CR>:sp term://nodemon -e py %<CR>
