默认情况下如何使用 elixirls 格式化 elixir 文件？

如何解决默认情况下如何使用 elixirls 格式化 elixir 文件？

我使用 elixirls lsp-client 和 efm-server（主要用于信条）在 Neovim 中处理长生不老药文件。 我想使用 lsp-config 来格式化 elixir 文件，并希望将其设为 vim.lsp.buf.formatting() 命令的默认 lsp-client。

目前，每次我尝试保存文件时，它都会要求我选择语言服务器，如下图所示。

如何使 elixirls 成为 vim.lsp.buf.formatting() 和 vim.lsp.buf.formatting_sync(nil,100) 命令的默认语言服务器？

我的相关 init.lua 文件如下：

-----------------------------------------------------------------------------------------------

-----------------------------------------------------------------------------------------------
local nvim_lsp = require("lspconfig")

-- Use an on_attach function to only map the following keys
-- after the language server attaches to the current buffer
local custom_attach = function(client,bufnr)
    local function buf_set_keymap(...)
        vim.api.nvim_buf_set_keymap(bufnr,...)
    end
    local function buf_set_option(...)
        vim.api.nvim_buf_set_option(bufnr,...)
    end

    -- Enable completion triggered by <c-x><c-o>
    buf_set_option("omnifunc","v:lua.vim.lsp.omnifunc")

    -- Mappings.
    local opts = {noremap = true,silent = true}

    -- See `:help vim.lsp.*` for documentation on any of the below functions

解决方法

使用 vim.lsp.buf.formatting_seq_sync() 而不是 vim.lsp.buf.formatting() 可以解决问题。
