Sure. I remember old days Tcl/Tk utility "expect" for such interactive scripting sessions. Open a pipes and communicate with process :) Today there are tools similar to "expect" for scripting command line utilities. Also Emacs works with GHCi (interro) in such way. Also Dante IMHO. Visual Studio Code Haskelly and Haskerro, etc.. 24.08.2018 14:58, Paum B. wrote:

Actually, I dont know if I have asked good question to what I need. So, I would like to run the process: stack ghc -- --interactive -XOverloadedStrings and then, somehow from 'outside' push string commands to it... On Fri, Aug 24, 2018 at 2:08 PM Paum B. wrote:

You should be able to run something like this: echo 'putStrLn "hi"' | stack exec -- ghci -XOverloadedStrings On Fri, Aug 24, 2018 at 8:21 AM, Paum B. wrote:

This are listing expect alternatives: https://en.wikipedia.org/wiki/Expect Btw, it's easy to be done in Python. Also my IMHO that better is to pass extension directives not in command line (it will be big) but in custom .ghci file with option "-ghci-script". 24.08.2018 15:27, David McBride wrote:
