这个错误的代码

import sequtils, sugar, yaml

let a: int
a = ""

产生巨大的错误信息

$ nimble run

  Verifying dependencies for yaml@0.14.0
   Building nim/app using c backend

是否可以使非必要的输出静音而只显示错误消息？喜欢

        ... /alex/projects/nim/src/test.nim(3, 5) Error: 'let' symbol requires an initialization

标签： nim-lang

【解决方案1】：

要使用编译器获得该行为，您将使用两个参数：

nim c --hints:off --verbosity:0 -r something.nim

您可以将其添加到 a compiler configuration file，如果这是您唯一需要的，您就不需要灵活。

关于 nimble，来自 it's changelog it seems the verbosity of commands has changed over time，查看相同的编译器参数是否适用于 nimble，如果不适用，请创建问题以请求此类行为。

【解决方案2】：

这部分有助于nimble --hints:off run
