如何在本地使用hoogle(如ctags)？

Question

我想在本地使用Hoogle,因此我可以在我的某个项目上运行搜索查询.[有一些文档这里 ],但我无法弄清楚如何得到它的工作.它说运行Haddock,但是haddock没有提供任何输出,只是吐出下面复制的警告.我还没有projectname.cabal文件,所以我无法使用该runhaskell Setup haddock --hoogle命令.

haddock coverage for ./Util.hs:     0/8   0%
haddock coverage for ./Blockify.hs:    0/16   0%
haddock coverage for ./Interpreter.hs:     0/9   0%
haddock coverage for AbstractSummarizer.hs:    0/10   0%

对不起,我的错,输出结果main.txt,我想我需要在某个时候清理我的项目.如果它没用,可以删除此问题.解决方案是:

PROJECTDIR> haddock --hoogle **/*.hs
PROJECTDIR> mv main.txt PROJNAME.txt
PROJECTDIR> hoogle convert PROJNAME.txt
PROJECTDIR> cp PROJNAME.txt PROJNAME.hoo HOOGLEDB
HOOGLEDB> hoogle combine -o default.hoo $(ls *.hoo | sed '/default/d')

HOOGLEDB ~/.cabal/share/hoogle-4.2.5/databases适合我.请注意,只有具有声明类型签名的函数才包含在数据库中.

干杯.抱歉垃圾邮件.
