Haskeline使得获取文件名标签完成功能变得非常容易:
module Main where
import System.Console.Haskeline
import System.Environment
mySettings :: Settings IO
mySettings = defaultSettings {historyFile = Just "myhist"}
main :: IO ()
main = do
args <- getArgs
let inputFunc = getInputLine
runInputT mySettings $ withInterrupt $ loop inputFunc 0
where
loop inputFunc n = do
minput <- handleInterrupt (return (Just "Caught interrupted"))
$ inputFunc (show n ++ ":")
case minput of
Nothing -> return ()
Just s -> do
outputStrLn ("line " ++ show n ++ ":" ++ s)
loop inputFunc (n+1)
它还提供了类似completeWord和completeQuotedWord的函数,它们应该能够以与使用completeFilename来实现上述功能相同的方式使用。
(换句话说,根据单词列表(例如,函数名称)而不是基于文件夹的内容来完成制表符完成)
任何人都可以提供一个工作示例 - 或工作代码 - 吗?
其他软件包(如HCL)的功能建议也很有帮助。

这是你想要的事吗?
import Data.List
wordList = [ "Apple", "Pear", "Peach", "Grape", "Grapefruit", "Slime Mold"]
searchFunc :: String -> [Completion]
searchFunc str = map simpleCompletion $ filter (str `isPrefixOf`) wordList
mySettings :: Settings IO
mySettings = Settings { historyFile = Just "myhist"
, complete = completeWord Nothing " \t" $ return . searchFunc
, autoAddHistory = True
}
将代码段中的mySettings
的定义替换为该代码,它应该可以正常工作。
