refactoring.nvim

The Refactoring library based off the Refactoring book by Martin Fowler

Setup

Requirements:

Treesitter
Lsp
Plenary

Basic Setup

Packer setup:

use {
    "ThePrimeagen/refactoring.nvim",
    requires = {
        {"nvim-lua/plenary.nvim"},
        {"nvim-treesitter/nvim-treesitter"}
    }
}

Example Config:

local refactor = require("refactoring")
refactor.setup()

-- telescope refactoring helper
local function refactor(prompt_bufnr)
    local content = require("telescope.actions.state").get_selected_entry(
        prompt_bufnr
    )
    require("telescope.actions").close(prompt_bufnr)
    require("refactoring").refactor(content.value)
end
-- NOTE: M is a global object
-- for the sake of simplicity in this example
-- you can extract this function and the helper above
-- and then require the file and call the extracted function
-- in the mappings below
M = {}
M.refactors = function()
    local opts = require("telescope.themes").get_cursor() -- set personal telescope options
    require("telescope.pickers").new(opts, {
        prompt_title = "refactors",
        finder = require("telescope.finders").new_table({
            results = require("refactoring").get_refactors(),
        }),
        sorter = require("telescope.config").values.generic_sorter(opts),
        attach_mappings = function(_, map)
            map("i", "<CR>", refactor)
            map("n", "<CR>", refactor)
            return true
        end
    }):find()
end
