Format current line immediately in INSERT mode as soon as you press ENTER:

Features

• Format the current line in real-time when you press ENTER.
• Seamless, no need to stop your work to run an extra command like gq or :Neoformat.
• When you are focusing on editing, everything is done without paying extra attention.
• No external process (eg. LSP servers) dependencies.
• Supported languages including Python, Lua, Ruby, and Javascript.

Requirements

• Vim with "+python3" feature.
• Python module "autopep8".

Quick Start

Install the plugin with vim-plug:

" Tell vim-plug to install python module with post-update hook
Plug 'skywind3000/vim-rt-format', { 'do': 'pip3 install autopep8' }

" By default, it will be triggered by `ENTER` in insert mode.
" set this to 1 to use `CTRL+ENTER` instead, and keep the  
" default `ENTER` behavior unchanged.
let g:rtf_ctrl_enter = 0

" Enable formatting when leaving insert mode
let g:rtf_on_insert_leave = 1

Enable plugin for current buffer:

:RTFormatEnable

Then you go.
