在emacs中，只加载基础配置。项目配置用脚本加载。go语言使用go-langserver和lsp-mode，其他的yasnippet，补全，都是基础功能。

所有emacs配置出现问题的原因都是对elisp了解少导致的，emacs的插件源有清华的也有emacs-china的，清华的地址：
(setq package-archives '(("gnu" . "http://mirrors.tuna.tsinghua.edu.cn/elpa/gnu/")
("melpa" . "http://mirrors.tuna.tsinghua.edu.cn/elpa/melpa/")))
future：
（1）自动安装package，放到自定义目录
（2）项目中创建一个空的.projectile配置文件，当打开一个项目的文件夹后会自动打开响应的lsp后端，开启lsp-mode。
首先安装polipo，然后写配置文件：
#必填
socksParentProxy = "localhost:1080"
socksProxyType = socks5
安装lsp的go语言后端gopls，lsp-mode包括UI之类的提供一套共同的操作，配置不同的后端就可以做成和ide一样：
GO111MODULE=on https_proxy=127.0.0.1:8123 http_proxy=127.0.0.1:8123 go get -v golang.org/x/tools/gopls@latest
安装bingo后端。
go语言补全，跳转，需要的工具参考：
https://blog.yuantops.com/tech/emacs-config-go-dev-environ/
要么多试几次，将包下载下来，要么更改go.mod，增加replace配置，示例如下：
module tx
require github.com/sirupsen/logrus v1.2.0 // indirect
replace (
golang.org/x/crypto v0.0.0-20180820150726-614d502a4dac => github.com/golang/crypto v0.0.0-20180820150726-614d502a4dac
golang.org/x/net v0.0.0-20180821023952-922f4815f713 => github.com/golang/net v0.0.0-20180826012351-8a410e7b638d
golang.org/x/text v0.3.0 => github.com/golang/text v0.3.0
golang.org/x/sys v0.3.0=>github.com/golang/sys v0.3.0
)
如果过程中卡主了，可以使用nload，回车键切换查看ip流量是否正常。
