[GitHub] [camel] essobedo opened a new pull request, #8688: CAMEL-18697: camel-core - Propose a DSL for languages

essobedo opened a new pull request, #8688:
URL: https://github.com/apache/camel/pull/8688

   Fix for https://issues.apache.org/jira/browse/CAMEL-18697
   
   ## Motivation
   
   For Java DSL then we have a language builder at `org.apache.camel.builder.ExpressionClause`
   
   This class is very verbose as for Java DSL we have overloaded methods to set the various options, but it can get too far like `tokenize` with 12 methods.
   
   Instead, we should propose a builder DSL class that the `RouteBuilder` can provide.
   
   ## Modifications:
   
   * Add a static nested class `Builder` to all existing languages
   * Add a factory for the builder of all the languages `LanguageBuilderFactory`
   * Add the method `expression()` to the `RouteBuilder` to give access to the factory of builders while defining the routes.
   * Add the method `expression(Expression)` to `BuilderSupport` in order to create a `ValueBuilder` from any expression
   
   ## Result
   
   It is now possible to create an expression using the fluent syntax as shown in the next example:
   
   ```
   from("file:data")
       .split(
           expression()
               .tokenize()
                   .token("(\\W+)\\s*")
                   .regex(true)
               .end()
       )
       .process("processEntry");
   ```
