Title: passing format a list of strings
Post by: two- on February 21, 2011, 01:16:14 AM
I have a function run-sh defined as so:
Code Select
(define (run-sh sTr) (exec (format {'%s'} sTr)))run-sh is a kind of basic function that takes input sTr - the shell command.

newLISP can call it like this:
Code Select
(run-sh {ls -a -l})or, so i wish. The problem is this is my error message:
Code Select
sh: ls -a -l: command not foundI know you're probably wondering 'why not use (exec ...?' but, let's say, if I wanted to do this, how can i pass a list of strings to run-sh such that the first string is the command name, and have newLISP pass the remaining strings as the command's arguments?

The single quotes are confusing the shell.


Code Select
(define (run-sh sTr) (exec (format {%s} sTr)))
   (run-sh {ls -a -l})


This is possible:


Code Select
(define (run-sh)
    (exec (format {%s} (join (args)))))

cormullion?!



I've missed you! It's not the same place around here without you, but I certainly understand if you have other priorities now. I myself am not here as much as I'd like to be anymore :-(



Are you trying out other languages, or have you given up on programming altogether? Either way, it's good to hear from you again.

Hi michael - Yes, I just pop in occasionally to catch up on the excitement :) ... I don't have much time to do anything worth sharing...
