copilot.lua

copilot.lua copied to clipboard

I just set this plugin up, and tried the simplest thing.

function sum(a: number, b: number) {
	// here I invoked the next function with <M-]>
}

It generated the suggestion just fine, but when I tried to accept it with <M-l>, I get this error:

E5108: Error executing lua: Vim:E945: Range too large in character class
stack traceback:
        [C]: in function 'substitute'
        ...ocal/share/nvim/plugged/copilot.lua/lua/copilot/util.lua:300: in function 'strutf16len'

I suspect I'm doing something wrong here, since this plugin is working for other folks. I'm using vim-plug and calling setup from a vimrc file, like this:

call plug#begin(has('nvim') ? stdpath('data') . '/plugged' : '~/.vim/plugged')
" ... other plugins

Plug 'zbirenbaum/copilot.lua'

call plug#end()

" Initialize github copilot
lua require('copilot').setup({})

What's the output of :Copilot version?

Neovim 0.9.1
copilot.vim 1.12.1
copilot.lua 3665ed0f3ef3ad68673df7195789d134d0d1fdb0
copilot/dist/agent.js 1.138.0
Node.js 18.17.1

FYI I just upgraded neovim to 0.9.4 and I still get the same result.

May be related, but I'm getting this error happens to me whenever I try to accept a suggestion:

[Copilot] failed to notify_accepted for:                         kill = "<C-c>",
Error: Vim:E945: Range too large in character class

The text is still entered into the buffer, but that error comes up every time I accept that suggestion.

Here is my version info:

And my configuration with lazy.nvim:

    {
        "zbirenbaum/copilot.lua",
        cmd = "Copilot",
        event = "InsertEnter",
        config = function ()
            require('copilot').setup({
                  panel = {
                    enabled = false,
                },
                suggestion = {
                    enabled = true,
                    auto_trigger = true,
                    debounce = 75,

                    },
                },
                filetypes = {
