加快GHC的编译速度 [英] Speed up compilation in GHC

问题描述

除 -O0 之外是否还有其他选项可以加快编译时间？

Is there options, except -O0, that can speed up compilation time?

没关系结果程序将不会优化。实际上，我只想经常快速地检查大型haskell软件包。

It's not matter if resulting programs will be not optimised. Actually I want to just type-check large haskell package often and fast.

标记 -fno-code 显着提高速度但由于该程序使用了TemplateHaskell，因此无法使用它。

Flag -fno-code dramatically speeds up compilation but it's not possible to use it because TemplateHaskell is used by this program.

推荐答案

看起来像是一个 hdevtools ！ Hdevtools被用来作为同名vim-plugin的后端，它直接从编辑器提供快速的语法和类型检查。重新加载模块时，速度与ghci一样快。我认为它可以在命令行中使用。

Looks like a task for hdevtools! Hdevtools is used to as a backend for vim-plugin of the same name and it provides speedy syntax and type checking, directly from the editor. It is about as fast as ghci when reloading modules. I assume that it can be used from the command line.

另一种方法是保持ghci实例运行并使用它来键入检查模块。

Another alternative would be to keep a ghci instance running and use that to type check your modules.
