Print in colors using the AppHelpTemplate about cli

This is because you are using a backquoted string - escape sequences (like \x) aren't interpreted in backquoted strings. You need to use a double quoted string instead.

Oh, thanks. This is my first time with a Go application so I don't know most of the things yet.

But, the problem is If I use a double quoted string, I can't make it multi-line (can I?)
I used just a single line for brevity, the actual template is this:

var AppHelpTemplate = `\x1b[33;1m{{.Name}} - {{.Usage}}\x1b[0m

Version: {{.Version}}

Usage:
    {{.Name}} [global options] [cheatsheet] <command> [<args>]


Commands:
    {{range .Commands}}{{.Name}}{{with .ShortName}}, {{.}}{{end}}{{ "\t" }}{{.Usage}}
    {{end}}

Global Options:
    {{range .Flags}}{{.}}
    {{end}}
`

You can use double quoted strings with + to concatenate them together.

var AppHelpTemplate = "\x1b[33;1m{{.Name}} - {{.Usage}}\x1b[0m" + `

Version: {{.Version}}

Usage:
{{.Name}} [global options] [cheatsheet] []

Commands:
{{range .Commands}}{{.Name}}{{with .ShortName}}, {{.}}{{end}}{{ "\t"
}}{{.Usage}}
{{end}}

Global Options:
{{range .Flags}}{{.}}
{{end}}

Examples:
{{.Name}} git Shows git cheatsheet

{{.Name}} -e at         Create a new cheatsheet named at
