In Turtle (Haskell), how can I get the output of a command, and do something with it?

Asked 2019-Nov-14 at 17:50

I'm a Haskell beginner, trying to translate a shell script into a Turtle script, just as an exercise. In BASH, I'd get the output of some command like so: cmdoutput=$(my-command -option 1 -option 2 and then I could do a case switch in BASH to echo out different messages or run different actions, depending on the value of cmdoutput. How can I achieve that in Haskell Turtle?

Edit: here's the shell script I'm trying to translate:

You can use inshell to run a command and capture its output.

QUESTION

How to print paths using Haskell Turtle library?

Asked 2017-Jul-14 at 01:54

To learn a bit about Turtle, I thought it would be nice to modify example from the tutorial. I chose to remove the reduntant "FilePath" from each line of the output thinking it would be a simple exercise.

And yet, despite author's efforts into making his library easy to use I nearly failed to use it to solve this simple problem.

I tried everyting I saw that looked like it would allow me to somehow lift >>= from IO into Shell: MonadIO, FoldM, liftIO, _foldIO with no success. I grew frustrated and only through reading Turtle source code I was able to find something that seems to work ("no obvious defects" comes to mind).

Why is this so hard? How does one logically arrive a solution using API of this library?

You don't lift >>= from IO into Shell. Shell already has a Monad instance that comes with its own >>= function. Instead you either lift IO actions into Shell with liftIO or run the shell with fold or foldM. Use sh to run the Shell when you don't care about the results.
