Emacs Scala Ensime：打开REPL不会从我的项目中加载任何东西 [英] Emacs Scala Ensime: Opening REPL does not load anything from my project

问题描述

我很确定我已经设置了Emacs，Ensime，SBT和Scala来正常工作。我可以编辑文件，看到类型错误，当我保存并成功尝试使用ensime的自动重构工具。

问题是当我打开一个REPL按 Cc Cv z 似乎似乎没有加载我的文件。

换句话说，如果我定义的东西像

class Moose {}

当我尝试使用 Moose 从REPL

  scala> ; Moose 
< console>：8：error：not found：value Moose 
 Moose 
 ^ 
 
 scala>新的Moose 
< console>：8：error：not found：type Moose 
 new Moose 
 ^ 
  

什么是最好的方法来加载某些东西，如当前的缓冲区内容到REPL？

解决方案

我发现REPL实际上没有问题。我一直在尝试通过按 Cc Cb b 来编译我的项目，并假定它正在使用缓冲区 * ENSIME-Compilation-Result * 将弹出以下选项：

 最新编译结果（q退出，TAB跳转到下一个错误）
 ---------------------------------------- 
 
 0错误，0警告。 
  

但是，我查看了 target / scala-2.10 / classes 目录，并发现没有生成 .class 文件。

当我从 sbt 的命令行编译时，我能够得到一个加载了我预计。

编辑：

我发布了一个后续问题： 使用Ensime构建会删除所有.class文件，但不编译任何内容。

I am pretty sure I have setup Emacs, Ensime, SBT, and Scala to work together properly. I am able to edit files and see type errors when I save and have successfully tried using ensime's autorefactoring tools.

The problem is when I open a REPL by pressing C-c C-v z it seems as if nothing from my file is loaded.

In other words if I define something like

class Moose {}

in my source file, this is what happens when I try to use Moose from the REPL

scala> Moose
<console>:8: error: not found: value Moose
              Moose
              ^

scala> new Moose
<console>:8: error: not found: type Moose
              new Moose
                  ^

What is the best way to load something, such as the current buffer contents into the REPL?

解决方案

I found out that there was actually no problem with the REPL. I had been trying to compile my project by pressing C-c C-b b and assumed it was working the buffer *ENSIME-Compilation-Result* would pop up with:

Latest Compilation Results (q to quit, TAB to jump to next error)
----------------------------------------

0 errors, 0 warnings.

But, I checked in the target/scala-2.10/classes directory and found that no .class files were being generated.

When I instead compiled from the command line with sbt, I was able to then get a REPL loaded with what I expected.

EDIT:

I posted a follow-up question: Building with Ensime deletes all .class files, but doesn't compile anything.
