尽管Haddock中存在错误，但仍构建本地Hoogle DB

Question

有没有办法在某些包中有Haddock错误的情况下构建一个lokal Hoogle DB。例如，在lokal Hoogle DB构建期间，是否有解决方法将这些包从Haddock子任务中排除？

举个具体的例子：

$ stack hoogle
No Hoogle database yet. Automatically building haddocks and hoogle database (use --no-setup to disable) ...
classy-prelude-yesod-1.5.0: configure
classy-prelude-yesod-1.5.0: build

与How to build with haddocks, but ignore haddock errors相关

Answer 1

stack hoogle大概是stack haddock周围的帮手，然后是hoogle generate --local。如果您只能为工作的项目生成Haddock输出，那么您可以手动执行hoogle generate --local。但是，我不知道有什么方法可以将stack haddock限制为只有一个子集，所以它可能并不实用。

另一种方法是使用hoogle generate <list of dependencies>，它将使用远程文档而不是本地文档，因此将跳过运行Haddock。
