Description
Implement functions to run Shell commands easier in the Iris applications. A simple implementation would be something like this (inspired by shellmet):
-- | Run the command but don't print it
shellSilent
:: FilePath -- ^ Executable name
-> [Text] -- ^ Arguments
-> IO ()
-- | Run the command and print the command itself to stderr
shell
:: Text -- ^ Prompt
-> FilePath -- ^ Executable name
-> [Text] -- ^ Arguments
-> IO ()
-- | Run the command, don't print it and return its stdout
shellRetSilent
:: FilePath -- ^ Executable name
-> [Text] -- ^ Arguments
-> IO Text
-- | Run the command, print it with prompt to stderr and return its stdout
shellRet
:: Text -- ^ Prompt
-> FilePath -- ^ Executable name
-> [Text] -- ^ Arguments
-> IO TextAlternatively, we can integrate with one of the existing and battle-tested libraries:
