如何使用堆栈台

本文介绍了如何使用堆栈台的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我一直在使用栈来处理一个Haskell应用程序，到目前为止，我已经能够构建和测试了，并且有兴趣查看性能，所以试过 stack bench 然而，这是所有似乎都发生的事情：

c：\Users\jk\projects\foo> ;堆栈长凳堆栈长凳

我不认为它可以做任何事情吗？我的应用程序似乎没有运行。 Presuembly有一些我缺少的配置？

解决方案

stack bench will运行在 foo.cabal 文件中定义的任何基准套件。没有看到它很难说更多，但请注意，您可以使用 -v 运行以获得更多输出。

从上面我看到的，但我猜你没有定义任何基准，所以 stack bench 什么都不做，因为没有什么可做的：）

I've been playing around with using stack for a little haskell application, so far I have been able to build and test fine and was interested in looking at performance so tried stack bench however this is all that seems to happen:

c:\Users\jk\projects\foo>stack bench stack bench

I don't think it can have done anything? My application does not appear to have run. Presuembly there is some configuration I am missing?

解决方案

stack bench will run any benchmark suites defined in your foo.cabal file. Without seeing it it's hard to say more, note though that you can run with -v to get more output.

From what I see above however I guess you don't have defined any benchmarks so stack bench does nothing because there is nothing to do :)
