LXQT-QTermWidget的编译
LXQT的编译说明
https://github.com/lxqt/lxqt/wiki/Building-from-source
流程如下：
1.安装Qt5。
yum install qt5-qtbase-devel qt5-qtsvg-devel qt5-qttools-devel qt5-qtx11extras-devel
2.安装CMake，一定用要官方包安装，并编辑bashrc文件。
export PATH=$PATH:/cmake-3.15.3/bin
3.下载lxqt-build-tools编译工具并安装。
git clone https://github.com/lxqt/lxqt-build-tools.git
假如是解压在~/lxqt/lxqt-build-tools目录下。
则创建编译目录~/lxqt/build
构建指令如下：
cmake ../lxqt-build-tools
make && make install
它会安装至/usr/local的某个目录下。
4.下载
git clone git@github.com:kxtry/qtermwidget.git
使用CLion构建及编译即可。
此版本已经与原版不一样，有修改。
原版可能无法编译完成，原因是QString("sdfsdfds")会编译不通过，因为从Qt5.9版本开始，QString(char *p)设置成私有函数了。

GoLang的AST语法树
package main
import (
"fmt"
"go/ast"
"go/parser"
"go/token"
)
func main() {
// src is the input for which we want to print the AST.
src := `
// @router /login [post]
// @router2 /login2 [post]
package main
func main() {
println("Hello, World!")
}
`
// Create the AST by parsing src.
fset := token.NewFileSet() // positions are relative to fset
f, err := parser.ParseFile(fset, "", src, parser.ParseComments)
if err != nil {
panic(err)
}
for _, comment := range f.Comments {
fmt.Println(comment.Text())
}
// Print the AST.
ast.Print(fset, f)
}

转义字符\e
Windows 平台下，conio.h 中有许多操作控制台颜色、格式的函数。但是再 Linux 平台下却没有类似的函数。经过在网上的一番搜索，找到了解决此问题的方法——转义字符\e。
注意，\e这种写法可能并不被你的编译器所支持（Linux下的GNU和Bash支持，亲测无误），因为他并不是ANSI C的。可以用\033代替。
