base on Color package for Go (golang) # color [](https://github.com/fatih/color/actions) [](https://pkg.go.dev/github.com/fatih/color) Color lets you use colorized outputs in terms of [ANSI Escape Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Go (Golang). It has support for Windows too! The API can be used in several ways, pick one that suits you.  ## Install ``` go get github.com/fatih/color ``` ## Examples ### Standard colors ```go // Print with default helper functions color.Cyan("Prints text in cyan.") // A newline will be appended automatically color.Blue("Prints %s in blue.", "text") // These are using the default foreground colors color.Red("We have red") color.Magenta("And many others ..") ``` ### RGB colors If your terminal supports 24-bit colors, you can use RGB color codes. ```go color.RGB(255, 128, 0).Println("foreground orange") color.RGB(230, 42, 42).Println("foreground red") color.BgRGB(255, 128, 0).Println("background orange") color.BgRGB(230, 42, 42).Println("background red") ``` ### Mix and reuse colors ```go // Create a new color object c := color.New(color.FgCyan).Add(color.Underline) c.Println("Prints cyan text with an underline.") // Or just add them to New() d := color.New(color.FgCyan, color.Bold) d.Printf("This prints bold cyan %s\n", "too!.") // Mix up foreground and background colors, create new mixes! red := color.New(color.FgRed) boldRed := red.Add(color.Bold) boldRed.Println("This will print text in bold red.") whiteBackground := red.Add(color.BgWhite) whiteBackground.Println("Red text with white background.") // Mix with RGB color codes color.RGB(255, 128, 0).AddBgRGB(0, 0, 0).Println("orange with black background") color.BgRGB(255, 128, 0).AddRGB(255, 255, 255).Println("orange background with white foreground") ``` ### Use your own output (io.Writer) ```go // Use your own io.Writer output color.New(color.FgBlue).Fprintln(myWriter, "blue color!") blue := color.New(color.FgBlue) blue.Fprint(writer, "This will print text in blue.") ``` ### Custom print functions (PrintFunc) ```go // Create a custom print function for convenience red := color.New(color.FgRed).PrintfFunc() red("Warning") red("Error: %s", err) // Mix up multiple attributes notice := color.New(color.Bold, color.FgGreen).PrintlnFunc() notice("Don't forget this...") ``` ### Custom fprint functions (FprintFunc) ```go blue := color.New(color.FgBlue).FprintfFunc() blue(myWriter, "important notice: %s", stars) // Mix up with multiple attributes success := color.New(color.Bold, color.FgGreen).FprintlnFunc() success(myWriter, "Don't forget this...") ``` ### Insert into noncolor strings (SprintFunc) ```go // Create SprintXxx functions to mix strings with other non-colorized strings: yellow := color.New(color.FgYellow).SprintFunc() red := color.New(color.FgRed).SprintFunc() fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error")) info := color.New(color.FgWhite, color.BgGreen).SprintFunc() fmt.Printf("This %s rocks!\n", info("package")) // Use helper functions fmt.Println("This", color.RedString("warning"), "should be not neglected.") fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.") // Windows supported too! Just don't forget to change the output to color.Output fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS")) ``` ### Plug into existing code ```go // Use handy standard colors color.Set(color.FgYellow) fmt.Println("Existing text will now be in yellow") fmt.Printf("This one %s\n", "too") color.Unset() // Don't forget to unset // You can mix up parameters color.Set(color.FgMagenta, color.Bold) defer color.Unset() // Use it in your function fmt.Println("All text will now be bold magenta.") ``` ### Disable/Enable color There might be a case where you want to explicitly disable/enable color output. the `go-isatty` package will automatically disable color output for non-tty output streams (for example if the output were piped directly to `less`). The `color` package also disables color output if the [`NO_COLOR`](https://no-color.org) environment variable is set to a non-empty string. `Color` has support to disable/enable colors programmatically both globally and for single color definitions. For example suppose you have a CLI app and a `-no-color` bool flag. You can easily disable the color output with: ```go var flagNoColor = flag.Bool("no-color", false, "Disable color output") if *flagNoColor { color.NoColor = true // disables colorized output } ``` It also has support for single color definitions (local). You can disable/enable color output on the fly: ```go c := color.New(color.FgCyan) c.Println("Prints cyan text") c.DisableColor() c.Println("This is printed without any color") c.EnableColor() c.Println("This prints again cyan...") ``` ## GitHub Actions To output color in GitHub Actions (or other CI systems that support ANSI colors), make sure to set `color.NoColor = false` so that it bypasses the check for non-tty output streams. ## Credits * [Fatih Arslan](https://github.com/fatih) * Windows support via @mattn: [colorable](https://github.com/mattn/go-colorable) ## License The MIT License (MIT) - see [`LICENSE.md`](https://github.com/fatih/color/blob/master/LICENSE.md) for more details ", Assign "at most 3 tags" to the expected json: {"id":"4663","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
