nim-lang - 如何以编程方式获取 nim 编译器版本？

Question

是否有任何常量变量或proc允许以字符串或数字形式访问编译器版本？

Answer 1

The version can be obtained as a string通过 system.NimVersion (记住 system 是隐式导入的):

echo NimVersion # 0.18.0

You can also access its component parts (MAJOR.MINOR.PATCH) 作为数字，如下所示:

echo NimMajor # 0
echo NimMinor # 18
echo NimPatch # 0

当与元组结合使用时，这使得检查版本的兼容性非常容易:

when (NimMajor, NimMinor, NimPatch) >= (0, 19, 0):
  echo "we're on at least Nim v0.19.0"
