TermHelp takes a text prompt and turns it into a command. For example, :TermHelp find command to search three levels deep for Makefile will insert this in the current terminal window:

$ find . -maxdepth 3 -name "Makefile"

This plugin assumes you have a terminal open inside of NeoVim, which you can do by default with :term. I suggest using vim-termhere so you can have an easy mapping for opening split terminals, and so the suggested terminal-buffer-only mappings below work.

Aside from :TermHelp [instructions], you can also select a failed command and ask for help - with this visual selection active:

$ find . type f -iname Makefile
find: ‘type’: No such file or directory
find: ‘f’: No such file or directory

Doing :Chat terminal_correction will output the fixed command. You can also specify addition instructions at the end of this, e.g. :Chat terminal_correction search for the CMake defining file instead gives:

find . -type f -iname CMakeLists.txt

Note the typo 'zstsd' - it knows we mean zstd:

You need CodeGPT.nvim, to be loaded after nvim-termhelp.

Add the following line to your init.vim or init.lua file within the plug call block:

Plug 'TamaMcGlinn/nvim-termhelp'
Plug 'dpayne/CodeGPT.nvim'

Then, run :PlugInstall in NeoVim to install the plugin.

In your init.lua, add the following snippet:

require("lazy").setup({
    -- Load 'nvim-termhelp' first
    { "TamaMcGlinn/nvim-termhelp" },
    -- Then load 'CodeGPT.nvim'
    {
        "dpayne/CodeGPT.nvim",
        config = function()
            -- Configuration for CodeGPT.nvim if needed
            -- For example, you might want to set some default options or key mappings for CodeGPT
            require('codegpt').setup({
                -- your configuration here
            })
        end,
        -- This ensures CodeGPT.nvim loads after nvim-termhelp has been loaded
        after = "nvim-termhelp",
    },
})

First, navigate to your Pathogen bundle directory, usually ~/.config/nvim/bundle. Then, clone the repository:

cd ~/.config/nvim/bundle
git clone /~https://github.com/TamaMcGlinn/nvim-termhelp.git 01-nvim-termhelp
git clone /~https://github.com/dpayne/CodeGPT.nvim.git 02-CodeGPT.nvim

Pathogen should load the plugin automatically the next time you start NeoVim.

Add the following to your init.vim or init.lua in the dein block:

call dein#add('TamaMcGlinn/nvim-termhelp')
call dein#add('dpayne/CodeGPT.nvim', {'depends': 'nvim-termhelp'})

In your init.lua, add:

use { 'TamaMcGlinn/nvim-termhelp', }
use {
    'dpayne/CodeGPT.nvim',
    after = 'nvim-termhelp', -- Ensure CodeGPT.nvim loads after nvim-termhelp
    config = function()
      -- Configuration for CodeGPT.nvim here
      require('codegpt').setup({
        -- your configuration here
      })
    end
}

If you are using a different plugin manager, please send me a PR adding the instructions for this plugin; refer to its documentation for instructions on adding plugins. The general approach involves adding the plugin's git repository URL (/~https://github.com/TamaMcGlinn/nvim-termhelp) to your plugin manager's configuration file or command.

I can recommend these mappings for your vimrc:

augroup termhelp
    autocmd FileType terminal nnoremap <buffer> <Leader>n :TermHelp 
    autocmd FileType terminal vnoremap <buffer> <Leader>n :Chat terminal_correction
    autocmd FileType terminal vnoremap <buffer> <Leader>nn :Chat terminal_correction<CR>
augroup END

or in lua:

vim.api.nvim_command([[
augroup termhelp
    autocmd FileType terminal nnoremap <buffer> <Leader>n :TermHelp<CR>
    autocmd FileType terminal vnoremap <buffer> <Leader>n :Chat terminal_correction
    autocmd FileType terminal vnoremap <buffer> <Leader>nn :Chat terminal_correction<CR>
augroup END
]])

Note that the terminal filetype doesn't work by default without using vim-termhere, because Justin thinks the empty string is a more sensible default for terminal buffers. See neovim/neovim#4465.

You can just use regular nnoremap to define it in all buffers:

nnoremap <Leader>n :TermHelp 
vnoremap <Leader>n :Chat terminal_correction 
vnoremap <Leader>nn :Chat terminal_correction<CR>

You should absolutely not set g:termhelp_learn_to_stop_worrying = v:true. This automatically runs the command generated, so you don't have time to check if the resulting command bricks your machine. Next, definitely don't run :TermHelp delete all files on the machine.

Have fun good luck DON'T PANIC!
