p4vasp: 重生
俗话说字越少，事儿越大。我觉得这个事情还是蛮重大的，标题就简单些吧，其实冒号也可以删掉。
言归正传：经过本人和Whitehare大神的不懈努力，终于把p4vasp升级到了python3，并给新版本命名为：p4vasp-py3
https://github.com/bigbrosci/p4vasp.git （记得切换到p4vasp-py3这个分支）目前支持的版本有Linux和Mac。Linux 版本可以运行在正常的系统比如Ubuntu，也可以在Windows的WSL中正常运行（也算是变相支持Windows吧）。MacOs 测试中M4 和 Intel的芯片都OK。 总之：不管什么系统，主打一个傻瓜式安装： 一个命令行直接安装完毕，不需要动脑子。
1 Linux系统的安装步骤 （Ubuntu为例）
在terminal中，复制粘贴下面的命令，然后运行。
1.1 下载p4vasp-py3。
mkdir ~/opt && cd ~/opt && git clone -b p4vasp-py3 https://github.com/bigbrosci/p4vasp.git
1.2 编译p4vasp-py3
cd p4vasp/ && bash ubuntu-start.sh
弹出来p4vasp的界面，就说明安装成功了。 关掉或者Control + C即可，就是这么直接。
1.3 编辑~/.bashrc 文件，将下面这一行添加到文件中。
alias p4v="$HOME/opt/p4vasp/run-p4vasp.sh"
以后就可以通过p4v这个命令来打开单个或者多个文件了。
2 Mac OS 安装：
2.1 下载：
mkdir ~/opt && cd ~/opt && git clone -b p4vasp-py3 https://github.com/bigbrosci/p4vasp.git
2.2 编译，类似Ubuntu，运行的脚本变成了macos-start.sh
cd p4vasp/ && bash macos-start.sh
2.3 修改~/.zshrc
alias p4v="$HOME/opt/p4vasp/run-p4vasp.sh"
2.4 在terminal中运行的时候直接敲命令即可。
p4v POSCAR

当我看到这个界面的时候，流下了欢喜的泪水（夸张的描述）。P4VASP，我最爱的模型编辑器，活过来啦！！！
