Execute a Haskell Script with Arguments

Plug In Actions
1

Since a KM native action doesn't exist, I created this plugin that executes Haskell code with parameters. This is currently in experimental phase. I hope this gets natively implemented someday.

Version 0.01

Execute a Haskell Script with Arguments.zip (9.8 KB)

Requirements:

Haskell downloads:

(runhaskell program should be at: /usr/local/bin/runhaskell)

The script should have an interact' :: (String -> String) -> IO () function to accept those arguments.

Notes:
I used some of the wonderful functions in the prelude-jxa library by Rob Trew. Could be found here: https://github.com/RobTrew/prelude-jxa

The plugin currently writes a temporary .hs file.

A Haskell playground could be found here (below Try it):

EDIT:

Example:

This example uses the modified interact' function.

This new version doesn't error if Arg has parenthesis (due to shell interpretation of parenthesis).

You seem to have a readme.md from one of my old plugins in there (Join a KM Array with a delimiter) :slight_smile:

Perhaps worth replacing with one which references this plugin ?

My apologies !

Just updated.
