Neovim lsp自动修复/修复当前？

Question

我一直在寻找一种类似于CoC的coc-fix-current的解决方案，但在Neovim 0.5中使用原生lsp，但我在documentation中没有找到这样的东西，有没有其他方法可以实现这一点？

Answer 1

我有这个问题，通过修改telescope.nvim插件用来列出和运行代码操作的代码，我想出了这个怪物：

local function run_action(action)
    if action.edit or type(action.command) == "table" then
        if action.edit then
            vim.lsp.util.apply_workspace_edit(action.edit)
        end
        if type(action.command) == "table" then
            vim.lsp.buf.execute_command(action.command)
        end
    else
        vim.lsp.buf.execute_command(action)
    end
end

local function do_action(action, client)
    if
      not action.edit
      and client
      and type(client.resolved_capabilities.code_action) == "table"
      and client.resolved_capabilities.code_action.resolveProvider
    then
        client.request("codeAction/resolve", action, function(err, real)
            if err then
                return
            end
            if real then
                run_action(real)
            else
                run_action(action)
            end
        end)
    else
        run_action(action) 
    end
end

return function() 
    local params = vim.lsp.util.make_range_params() -- get params for current position
    params.context = {
        diagnostics = vim.lsp.diagnostic.get_line_diagnostics(),
        only = {"quickfix"}
    }

    local results, err = vim.lsp.buf_request_sync(
        0, -- current buffer
        "textDocument/codeAction", -- get code actions
        params,
        900
    )

    if err then return end

    if not results or vim.tbl_isempty(results) then
        print "No quickfixes!"
        return
    end

    -- we have an action!
    for cid, resp in pairs(results) do
        if resp.result then
            for _, result in pairs(resp.result) do 
                -- this is the first action, run it
                do_action(result, vim.lsp.get_client_by_id(cid))
                return
            end
        end 
    end

    print "No quickfixes!"
end

因为它是lua，所以需要将它放在nvim搜索模块的某个.lua文件中(例如，作为~/.config/nvim/lua/lsp_fixcurrent.lua)，然后绑定到:lua require("lsp_fixcurrent")()

也许你正在寻找：vim.lsp.buf.code_action()
