Installation and Configuration

You should run the require("fittencode").setup(options) function to run this plugin. Here is an example with lazy.nvim:

{
    "fakerepic/fittencode.lua",
    config = function()
        require("fittencode").setup({
            -- config options go here, if any
        })
    end
}

The following is the default configuration, which is used when no options are provided:

require("fittencode").setup({
    token_path = vim.fn.stdpath('cache') .. '/fittencode.json',
    suggestion = {
        enabled_at_startup = true,
        auto_trigger = {
            debounce = 1000,
            enabled_by_default = false,
        },
        keymap = {
            generate = '<C-L>',
            accept = '<C-;>',
            dismiss = '<C-M>',
        },
    },
})

• copilot.lua - Borrowed some ideas and snippets from here

Others

Currently there is no official neovim binding for Fitten Code, and this plugin was developed mainly to facilitate self-use. It seems that other developers have already built fittencode.nvim, but it requires nightly version of neovim, I published this one anyway :) Some of the other official features may be added if Fitten Code reveals more API details.
