rivescript java
0.11.0 - August 6, 2019
這是為 Java 程式語言編寫的 RiveScript 解譯器函式庫。 RiveScript 是聊天機器人的腳本語言，可以輕鬆編寫觸發器/響應對來建立機器人的智慧。
RiveScript 是一種用於編寫聊天機器人的腳本語言。它的語法非常簡單，旨在易於閱讀和快速編寫。
RiveScript 的簡單範例如下：
+ hello bot
- Hello human.
這與用戶的消息“hello bot”匹配，並會回复“Hello human”。或者舉一個稍微複雜一點的例子：
+ my name is *
* == => >Wow, we have the same name!
* != undefined => >Did you change your name?
- >Nice to meet you, !

若要在 Web 瀏覽器中測試 RiveScript，請嘗試 RiveScript Playground。
也請查看RiveScript 社群 Wiki ，以了解 RiveScript 的常見設計模式以及提示和技巧。
將rivescript-core依賴項新增到您的專案中：

}如果您想在 Spring Boot 應用程式中使用 RiveScript，請參閱 Spring Boot Starter 部分。
當用作編寫自己的聊天機器人的庫時，概要如下：
import com . rivescript . Config ;
import com . rivescript . RiveScript ;
// Create a new bot with the default settings.
RiveScript bot = new RiveScript ();
// To enable UTF-8 mode, you'd have initialized the bot like:
RiveScript bot = new RiveScript ( Config . utf8 ());
// Load a directory full of RiveScript documents (.rive files)
bot . loadDirectory ( "./replies" );
// Load an individual file.
bot . LoadFile ( "./testsuite.rive" );
// Sort the replies after loading them!
bot . sortReplies ();
// Get a reply.
String reply = bot . reply ( "user" , "Hello bot!" ); rivescript-core發行版還包括一個用於測試 RiveScript 機器人的互動式 shell。使用磁碟上包含 RiveScript 文件的資料夾的路徑來執行它。例子：
java com.rivescript.cmd.Shell [options]
com.rivescript.RiveScript建構函式採用可選的Config實例。這是包含所有支援選項的完整範例。您只需為配置選項提供與預設值不同的值。
RiveScript bot = new RiveScript ( Config . newBuilder ()
. throwExceptions ( false ) // Whether exception throwing is enabled
. strict ( true ) // Whether strict syntax checking is enabled
. utf8 ( false ) // Whether UTF-8 mode is enabled
. unicodePunctuation ( "[.,!?;:]" ) // The unicode punctuation pattern
. forceCase ( false ) // Whether forcing triggers to lowercase is enabled
. concat ( ConcatMode . NONE ) // The concat mode
. depth ( 50 ) // The recursion depth limit
. sessionManager ( sessionManager ) // The session manager for user variables
. errorMessages ( errors ) // Map of custom error messages
. build ());為了方便起見，您可以使用快捷方式：
// The default constructor uses a basic configuration.
RiveScript bot = new RiveScript ();
// This is similar as:
RiveScript bot = new RiveScript ( Config . basic ());
// To use the basic configuration with UTF-8 mode enabled use:
RiveScript bot = new RiveScript ( Config . utf8 ());RiveScript 中的 UTF-8 支援被認為是實驗性功能。預設情況下它是禁用的。
預設情況下（未啟用 UTF-8 模式），觸發器只能包含基本 ASCII 字元（無外來字元），且使用者的訊息將移除除字母、數字和空格之外的所有字元。這意味著，例如，您無法在 RiveScript 回覆中捕獲用戶的電子郵件地址，因為 @ 和 .人物。
啟用 UTF-8 模式後，這些限制將會解除。觸發器僅限於不包含某些元字符，例如反斜杠，並且用戶訊息僅去除反斜杠和 HTML 尖括號（如果您在 Web 應用程式中使用 RiveScript，則可以防止明顯的 XSS）。此外，常見的標點符號被刪除，預設為[.,!?;:] 。這可以透過向Config.Builder#unicodePunctuation()方法提供新的正規表示式字串來覆寫。例子：
// Make a new bot with UTF-8 mode enabled and override the punctuation
characters that get stripped from the user 's message.
RiveScript bot = new RiveScript ( Config . Builder
. utf8 ()
. unicodePunctuation ( "[.,!?;:]" )
. build ()); RiveScript 中的
將rivescript-spring-boot-starter依賴項新增到您的專案中：
行家：
< dependency >
< groupId >com.rivescriptgroupId >
< artifactId >rivescript-spring-boot-starterartifactId >

dependencies {
compile " com.rivescript:rivescript-spring-boot-starter:0.10.0 "
}啟動器將自動將rivescript-core依賴項新增至您的專案中，並觸發自動配置以建立RiveScript機器人實例。
儘管自動配置將使用合理的預設值來建立機器人實例，但可以在application.properties / application.yml檔案（或作為命令列開關）中指定以下屬性來自訂自動配置行為：
rivescript:
enabled: true # Enable RiveScript for the application.
source-path: classpath:/rivescript/ # The comma-separated list of RiveScript source files and/or directories.
file-extensions: .rive, .rs # The comma-separated list of RiveScript file extensions to load.
throw-exceptions: false # Enable throw exceptions.
strict: true # Enable strict syntax checking.
utf8: false # Enable UTF-8 mode.
unicode-punctuation: [.,!?;:] # The unicode punctuation pattern (only used when UTF-8 mode is enabled).
force-case: false # Enable forcing triggers to lowercase.
concat: none # The concat mode (none|newline|space).
depth: 50 # The recursion depth limit.
error-messages: # The custom error message overrides. For instance `rivescript.error-messages.deepRecursion=Custom Deep Recursion Detected Message`
object-handlers: # The comma-separated list of object handler names to register (currently supported: `groovy`, `javascript`, `ruby`).若要在建立的RiveScript機器人實例中自動註冊自訂 Java 子程式和/或非預設支援的物件處理程序，請在應用程式上下文中定義適當的 bean，例如：
@ Bean public Map < String , Subroutine > subroutines () { // The key is the name of the Java object macro to register. Map < String , Subroutine > subroutines = new HashMap <>(); subroutines . put ( "subroutine1" , new Subroutine1 ()); subroutines . put ( "subroutine2" , new Subroutine2 ()); return subroutines ; } @ Bean public Map < String , ObjectHandler > objectHandlers () { // The key is the name of the programming language to register. Map < String , ObjectHandler > objectHandlers = new HashMap <>(); objectHandlers . put ( "handler1" , new ObjectHandler1 ()); objectHandlers . put ( "handler2" , new ObjectHandler2 ()); return objectHandlers ; }
若要編譯、測試、建置所有 jar 和文檔，請執行：
./gradlew build
若要將所有 jar 安裝到本機 Maven 快取中，請執行：
./gradlew install
/samples資料夾包含 Java RiveScript 機器人實作的各種範例。
rsbot - RSBot.java是使用com.rivescript.cmd.Shell的簡單實作。
這些命令可以在 RSBot 中的輸入提示處使用：
/quit - Quit the program
/dump topics - Dump the internal topic/trigger/reply struct (debugging)
/dump sorted - Dump the internal trigger sort buffers (debugging)
/last - Print the last trigger you matched.
要執行RSBot以開始與基於 Eliza 的演示運行聊天：
./gradlew :rivescript-samples-rsbot:runBot --console plain
spring-boot-starter-rsbot - 此範例使用 RiveScript Spring Boot Starter 自動設定RiveScript機器人實例。
要開始與演示機器人聊天，請運行：
./gradlew :rivescript-samples-spring-boot-starter-rsbot:bootRun --console plain
