Hi all, I'm a big fan of FZF https://github.com/junegunn/fzf and I wanted to make an xmonad integration, to work like Util.Dmenu https://hackage.haskell.org/package/xmonad-contrib-0.13/docs/XMonad-Util-Dme.... I'm quite new to Haskell and I got some problems to do it. The main problem I have is that fzf needs to run in a shell and when I run an external terminal, it sucessfully pops up, but then the rest of the code continue to be executed and I can't wait for the output of fzf. Moreover, fzf give an output in the terminal, but then how do I get the output in my haskell code? I tried several think and the closest I got is to write the result of fzf in a file and read it back, but I cannot wait until my terminal shutdown to read my file, I have something like: *(filePath, handle) <- openTempFile "*path*" "fzf"* *hClose handle* *(_, _, _, procHandle) <- runInteractiveCommand ("xterm -e '*dataForFZF* | fzf >" ++ filePath ++"'")* *-- Here I need to wait that my term close, I tried: waitForProcess procHandle* *-- But it just freeze my Xmonad, and not sure a while loop on getProcessExitCode is better* *str <- readFile filePath* doSomethingWith* str* *removeFile filePath* Anyone has a hint to do this? Thanks a lot, cheers. Thomas Droxler
