Python LSP for Refactoring

Warning

This is still highly experimental and it does not fully work yet.

Test the project and contributing

Once the project installed, you can start the LSP with: prlsp serve

In the LSP client, make a rcp connection to "127.0.0.1:8989".

If you use neovim, you can add in your config these helper functions:

local client_id = nil
local n_clients = 0
local attached_clients = {}


EnablePyrefactorLSP = function()
    if client_id == nil then
        client_id = vim.lsp.start({
            name = "pyrefactorlsp",
            cmd = vim.lsp.rpc.connect("127.0.0.1", 8989),
            root_dir = vim.fs.dirname(vim.fs.find({ "pyproject.toml", "setup.py" }, { upward = true })[1]),
        })
    end
    local buf = vim.api.nvim_get_current_buf()
    vim.lsp.buf_attach_client(buf, client_id)
    table.insert(attached_clients, buf)
    n_clients = n_clients + 1
end

DisablePyrefactorLSP = function()
    if client_id then
        local buf = vim.api.nvim_get_current_buf()
        vim.lsp.buf_detach_client(buf, client_id)
        for k, v in ipairs(attached_clients) do
            if v == buf then
                table.remove(attached_clients, k)
                n_clients = n_clients - 1
                break
            end
        end
    end
    if n_clients == 0 then
        vim.lsp.stop_client(client_id)
        client_id = nil
        attached_clients = {}
    end
end

StopPyrefactorLSP = function()
    if client_id then
        for _, buf in ipairs(attached_clients) do
            vim.lsp.buf_detach_client(buf, client_id)
        end
        vim.lsp.stop_client(client_id)
        client_id = nil
        n_clients = 0
        attached_clients = {}
    end
end

vim.cmd([[
  command! -range PyreEnable  execute 'lua EnablePyrefactorLSP()'
]])
vim.cmd([[
  command! -range PyreDisable  execute 'lua DisablePyrefactorLSP()'
]])
vim.cmd([[
  command! -range PyreStop  execute 'lua StopPyrefactorLSP()'
]])

You can then start the LSP with :PyreEnable.
