Top Forums UNIX for Beginners Questions & Answers Are the brains of the UNIXoid working correctly? Post 303031445 by Corona688 on Thursday 28th of February 2019 10:46:42 AM

Code:
T=0 ; for X in {2..100} ; do ((T+=X)) ; done

Loses at code golf, but wins in a world where code must be read, understood, and maintained.

More seriously, Haskell won't replace shell, they've got different jobs. Haskell's real opportunities are perl and python, two omnipresent languages ill-equipped for formal math/logic but often pressed into service with the assistance bolt-on modules. This works but the syntax of calling modules for something you'd expect a builtin to do is inevitably ugly. Something with more orthogonal data structures could do a lot more with a lot less kludge. What can Haskell's data structures do?

NAME
runghc - program to run Haskell programs without first having to compile them. SYNOPSIS
runghc [runghc|flags] [GHC|flags] module [program|flags]... DESCRIPTION
runghc is considered a non-interactive interpreter and part of The Glasgow Haskell Compiler. runghc is a compiler that automatically runs its results at the end. OPTIONS
the flags are: -f it tells runghc which GHC to use to run the program. If it is not given then runghc will search for GHC in the directories in the system search path. runghc -f /path/to/ghc -- runghc will try to work out where the boundaries between [runghc flags] and [GHC flags], and [GHC flags] and module are, but you can use a -- flag if it doesn't get it right. For example, runghc -- -fglasgow-exts Foo means runghc won't try to use glasgow-exts as the path to GHC, but instead will pass the flag to GHC. EXAMPLES
runghc foo runghc -f /path/to/ghc foo runghc -- -fglasgow-exts Foo SEE ALSO
