+# Jibber Jabber [![Build Status](https://travis-ci.org/cubiest/jibberjabber.svg?branch=master)](https://travis-ci.org/cubiest/jibberjabber)
+
+Jibber Jabber is a GoLang Library that can be used to detect an operating system's current language, plus helper functionalities for app development.
+
+
+## OS Support
+
+UNIX: **GNU/Linux**, **macOS**, **FreeBSD**, **OpenBSD**, **NetBSD**  
+via the `LC_MESSAGES`, `LC_ALL` and `LANG` environment variables. They are checked in the aforementioned order.  
+These variables are used in ALL versions of UNIX for language detection.
+
+**Windows**  
+via [GetUserDefaultLocaleName](https://docs.microsoft.com/en-gb/windows/win32/api/winnls/nf-winnls-getuserdefaultlocalename) and [GetSystemDefaultLocaleName](https://docs.microsoft.com/en-gb/windows/win32/api/winnls/nf-winnls-getsystemdefaultlocalename) system calls. These calls are supported in Windows Vista and up.
+
+
+
+## DetectIETF
+
+`DetectIETF` will return the current locale as a string. The format of the locale will be the [ISO 639](http://en.wikipedia.org/wiki/ISO_639) two-letter language code, a DASH, then an [ISO 3166](http://en.wikipedia.org/wiki/ISO_3166-1) two-letter country code.
+
+**Example:**
+```golang
+	userLocale, err := jibberjabber.DetectIETF()
+	println("Locale:", userLocale)
+```
+
+
+## DetectLanguage
+`DetectLanguage` will return the current language as a string. The format will be the [ISO 639](http://en.wikipedia.org/wiki/ISO_639) two-letter language code.
+
+also import the following packages for parsing the returned locale
+```golang
+	"golang.org/x/text/language"
+	"golang.org/x/text/language/display"
+
+```
+
+
+**Example:**
+```golang
+	userLanguage, err := jibberjabber.DetectLanguage()
+	println("Language:", userLanguage)
+	languageTag, parseErr := language.Parse(userLanguage)
+	println("Language:", display.Self.Name(languageTag))
+	
+```
+
+
+## DetectLanguageTag
+
+`DetectLanguageTag` will return the current language as a language tag as specified by `"golang.org/x/text/language"`.
+
+**Example:**
+```golang
+	languageTag, parseErr := jibberjabber.DetectLanguageTag()
+	println("Language:", display.Self.Name(languageTag))
+	
+```
+
+
+## DetectTerritory
+
+`DetectTerritory` will return the current locale territory as a string. The format will be the [ISO 3166](http://en.wikipedia.org/wiki/ISO_3166-1) two-letter country code.
+
+**Example:**
+```golang
+	localeTerritory, err := jibberjabber.DetectTerritory()
+	println("Territory:", localeTerritory)
+```
+
+
+## About Errors in Detect
+
+All the Detect commands will return an error if they are unable to read the Locale from the system.
+
+For Windows, additional error information is provided due to the nature of the system call being used.
+
+
+## Helper Singleton
+
+There is a singleton you can, but don't have to, use. It helps you define and later check which locales you support in your application - if not, apply a fallback language locale.
+
+**Example:**
+```golang
+	langServer := jibberjabber.LanguageServer()
+	langServer.SetSupportedLanguages(map[language.Tag]string{
+		language.German:  "active.de.toml",
+		language.English: "active.en.toml",
+	}
+	langServer.SetFallbackLanguage(language.English)
+	langLocale, err := langServer.StringToSupportedLanguageTag("something") // returns `language.English`
+	if err != nil {
+		log.Printf("failed fetching supported language locale, use fallback language locale %q\n", display.Self.Name(langLocale))
+	}
+```

+// Package tcpproxy lets users build TCP proxies, optionally making
+// routing decisions based on HTTP/1 Host headers and the SNI hostname
+// in TLS connections.
+//
+// Typical usage:
+//
+//     var p tcpproxy.Proxy
+//     p.AddHTTPHostRoute(":80", "foo.com", tcpproxy.To("10.0.0.1:8081"))
+//     p.AddHTTPHostRoute(":80", "bar.com", tcpproxy.To("10.0.0.2:8082"))
+//     p.AddRoute(":80", tcpproxy.To("10.0.0.1:8081")) // fallback
+//     p.AddSNIRoute(":443", "foo.com", tcpproxy.To("10.0.0.1:4431"))
+//     p.AddSNIRoute(":443", "bar.com", tcpproxy.To("10.0.0.2:4432"))
+//     p.AddRoute(":443", tcpproxy.To("10.0.0.1:4431")) // fallback
+//     log.Fatal(p.Run())
+//
+// Calling Run (or Start) on a proxy also starts all the necessary
+// listeners.
+//
+// For each accepted connection, the rules for that ipPort are
+// matched, in order. If one matches (currently HTTP Host, SNI, or
+// always), then the connection is handed to the target.
+//
+// The two predefined Target implementations are:
+//
+// 1) DialProxy, proxying to another address (use the To func to return a
+// DialProxy value),
+//
+// 2) TargetListener, making the matched connection available via a
+// net.Listener.Accept call.
+//
+// But Target is an interface, so you can also write your own.
+//
+// Note that tcpproxy does not do any TLS encryption or decryption. It
+// only (via DialProxy) copies bytes around. The SNI hostname in the TLS
+// header is unencrypted, for better or worse.
+//
+// This package makes no API stability promises. If you depend on it,

 The following is a set of guidelines to follow when contributing to this package. These are not hard rules, please use common sense and feel free to propose changes to this document in a pull request.
 
-## Table of Contents
-
-1. [Code of Conduct](#code-of-conduct)
-1. [Getting Help](#getting-help)
-1. [Filing a Bug Report](#how-to-file-a-bug-report)
-1. [Suggesting an API change](#suggesting-an-api-change)

-
 ## Code of Conduct
 
 This project and its contibutors are expected to uphold the [Go Community Code of Conduct](https://golang.org/conduct). By participating, you are expected to follow these guidelines.
 
 ## Getting help
 
-Feel free to [open up an issue](https://github.com/AlecAivazis/survey/v2/issues/new) on GitHub when asking a question so others will be able to find it. Please remember to tag the issue with the `Question` label so the maintainers can get to your question as soon as possible. If the question is urgent, feel free to reach out to `@AlecAivazis` directly in the gophers slack channel.
-
-## How to file a bug report
-
-Bugs are tracked using the Github Issue tracker. When filing a bug, please remember to label the issue as a `Bug` and answer/provide the following:
-
-1. What operating system and terminal are you using?
-1. An example that showcases the bug.
-1. What did you expect to see?
-1. What did you see instead?
-
-## Suggesting an API change
-
-If you have an idea, I'm more than happy to discuss it. Please open an issue and we can work through it. In order to maintain some sense of stability, additions to the top-level API are taken just as seriously as changes that break it. Adding stuff is much easier than removing it.
+* [Open an issue](https://github.com/AlecAivazis/survey/issues/new/choose)
+* Reach out to `@AlecAivazis` or `@mislav` in the Gophers slack (please use only when urgent)
 
 ## Submitting a contribution
 
-In order to maintain stability, most features get fully integrated in more than one PR. This allows for more opportunity to think through each API change without amassing large amounts of tech debt and API changes at once. If your feature can be broken into separate chunks, it will be able to be reviewed much quicker. For example, if the PR that implemented the `Validate` field was submitted in a PR separately from one that included `survey.Required`, it would be able to get merge without having to decide how many different `Validators` we want to provide as part of `survey`'s API.
-
 When submitting a contribution,
 
-- Provide a description of the feature or change
-- Reference the ticket addressed by the PR if there is one
-- Following community standards, add comments for all exported members so that all necessary information is available on godocs
-- Remember to update the project README.md with changes to the high-level API
-- Include both positive and negative unit tests (when applicable)
-- Contributions with visual ramifications or interaction changes should be accompanied with the appropriate `go-expect` tests. For more information on writing these tests, see [Writing and Running Tests](#writing-and-running-tests)
+- Try to make a series of smaller changes instead of one large change
+- Provide a description of each change that you are proposing
+- Reference the issue addressed by your pull request (if there is one)
+- Document all new exported Go APIs
+- Update the project's README when applicable
+- Include unit tests if possible
+- Contributions with visual ramifications or interaction changes should be accompanied with an integration test—see below for details.

 ## FAQ
 
-### Why isn't sending a SIGINT (aka. CTRL-C) signal working?
+### What kinds of IO are supported by `survey`?
 
-When you send an interrupt signal to the process, it only interrupts the current prompt instead of the entire process. This manifests in a `github.com/AlecAivazis/survey/v2/terminal.InterruptErr` being returned from `Ask` and `AskOne`. If you want to stop the process, handle the returned error in your code:
+survey aims to support most terminal emulators; it expects support for ANSI escape sequences.
+This means that reading from piped stdin or writing to piped stdout is **not supported**,
+and likely to break your application in these situations. See [#337](https://github.com/AlecAivazis/survey/pull/337#issue-581351617)
+
+### Why isn't Ctrl-C working?
+
+Ordinarily, when you type Ctrl-C, the terminal recognizes this as the QUIT button and delivers a SIGINT signal to the process, which terminates it.
+However, Survey temporarily configures the terminal to deliver control codes as ordinary input bytes.
+When Survey reads a ^C byte (ASCII \x03, "end of text"), it interrupts the current survey and returns a
+`github.com/AlecAivazis/survey/v2/terminal.InterruptErr` from `Ask` or `AskOne`.
+If you want to stop the process, handle the returned error in your code:
 
 ```go
 err := survey.AskOne(prompt, &myVar)
-if err == terminal.InterruptErr {
-	fmt.Println("interrupted")
-
-	os.Exit(0)
-} else if err != nil {
-	panic(err)
+if err != nil {
+	if err == terminal.InterruptErr {
+		log.Fatal("interrupted")
+	}
