nvim-ghost.nvim

This is a neovim plugin for GhostText

Installation

Install it using your favourite plugin manager, e.g. for vim-plug -

Plug 'subnut/nvim-ghost.nvim'

Usage

Really, it's that simple!

Features

Customization

Specifying a different port

The default is 4001, which corresponds to the default value set in the browser extension. If you want to use a different value, simply add the following line to your init.vim -

let g:nvim_ghost_server_port = 4001

Replace 4001 with the port number you have set in the browser extension

Custom settings according to website

When you trigger GhostText, nvim-ghost triggers an User autocommand. You can listen for that autocommand and run your own commands (e.g. setting filetype)

NOTE: All the autocommands should be in the nvim_ghost_user_autocommands augroup

Some examples -

" Autocommand for a single website (i.e. stackoverflow.com)
au nvim_ghost_user_autocommands User www.stackoverflow.com setfiletype markdown

" Autocommand for a multiple websites
au nvim_ghost_user_autocommands User www.reddit.com,www.github.com setfiletype markdown

" Autocommand for a domain (i.e. github.com)
au nvim_ghost_user_autocommands User *github.com setfiletype markdown

" Multiple autocommands can be specified like so -
augroup nvim_ghost_user_autocommands
  au User www.reddit.com,www.stackoverflow.com setfiletype markdown
  au User www.reddit.com,www.github.com setfiletype markdown
  au User *github.com setfiletype markdown
augroup END

Suppressing all messages

If you want to suppress all messages from nvim-ghost, then add the following to your init.vim -

let g:nvim_ghost_super_quiet = 1

Start manually

:warning: EXPERIMENTAL: hasn't been tested thoroughly
Add this line to your init.vim -

let g:nvim_ghost_autostart = 0

and then, when you need the plugin, run :GhostTextStart to enable the plugin for that specific neovim instance.

Disable the plugin

If, for any reason, you want to disable the plugin completely, add this to your init.vim -

let g:nvim_ghost_disabled = 1


Other Operating Systems

This plugin uses a binary with its own packaged version of python3 and comes with the required packages pre-installed, but the binary itself needs to be made on a machine running the same OS as the target machine. (i.e. the Linux binary needs to be built on a Linux machine, macOS binary on macOS, etc.)

The binaries are made using GitHub Actions, which only provides Linux, Windows and macOS containers. So, it is impossible for me to distribute binaries for other OSes.

So, to use this plugin, you shall need to install python3 (with pip) in your system. Then, go to the directory where this plugin is installed and run -

python -m pip install -r requirements.txt

This needs to be done only once. This command installs the required packages from pip.

Next, add the following two lines to your init.vim -

let g:nvim_ghost_use_script = 1
let g:nvim_ghost_python_executable = '/usr/bin/python'

Replace /usr/bin/python with the absolute path of the python executable installed in your system. Now, restart neovim, and the plugin should work.

If you face any problems, please open an issue. I will try my best to work out a solution for you.
