Seq [설정 [_]]에서 설정 값을 검사하는 방법?

Question

SbtTwirl에 정의 된 twirlSettings의 값을 읽으려고합니다.

할 방법이 있습니까? 아마도 sbt inspect을 사용하고 있을까요? 아니면 다른 방법이 있습니까? 내 Twirl 템플릿이 컴파일되지 않는 이유를 알아 내려고하면서 값을 읽어야합니다.

Answer 1

twirlSettings은 그렇듯이 sbt inspect이 될 수있는 열쇠가 아닙니다. Seq[Setting[_]]입니다. 그러나 제작 한 개별 설정을 검사 할 수 있습니다. 예를 들어 :

> inspect compile:compileTemplates::sourceDirectories 

는 line 40에 의해 생성되는 것을 검사 :

sourceDirectories in compileTemplates := Seq(sourceDirectory.value/"twirl"), 

Answer 2

다른 대답은 미세하지만 consoleProject 또는 eval를 사용하여 조금 더 복잡 방법이있다.

는 consoleProject에서 다음 세션을 참조하십시오

[root]> help consoleProject 
Starts the Scala interpreter with the sbt and the build definition on the classpath and useful imports.

SbtTwirl에 대한 액세스를 갖는 당신은 당신이 원하는 어느 것 무엇이든 할, 그러나 당신이 그렇게 쉽게되지 않을 수도 있습니다 consoleProject에서 생활하기 때문에 추측에주의 할 수있다 스칼라를 사용하여 손가락 끝에 build.sbt - .value 매크로가 있습니다. 당신은 스칼라 세계에 있습니다.

eval을 사용하면 유용 할 수 있습니다.

[root]> help eval 
eval <expression> 

    Evaluates the given Scala expression and prints the result and type. 

[root]> eval SbtTwirl.twirlSettings
