Re: Command line to array

Ok, I've got more to add, sorry folks. $previous_writeup =~ s/Command line/STDIN/gi; Ok, here's some new and (hopefully) inmproved writeup material.

I want to be able to run

table({rows => '2'}, "Cell 1", "Cell", "Blah, blah");
[download]

prompt:) table {rows => '2'}, "Cell 1", "Cell", "Blah, blah"
[download]

But I want to be able to do that with any subroutine. Examples of params could be as follows

[ [ "Blah", "Blah" ], [ "Blah", "Blah" ] ]

"Blah, Blah, Blah"

[ [ "Baz", [ { Wow => "that's Nesting" }, "Bar" ], "foo" ],
[ "More", "Too lazy to be creative", "More here" ] ]
[download]

I hope that this make sense. Thank you for excusing my stupity today.

eval is the easiest way to do this, since you don't end up with your own mini-language to parse; just let perl do it. Here's a very primitive command-line example: `% perl -MData::Dumper -nwe 'chomp; ($sub, $rest) = split / +/, $_, 2; eval "$sub($rest)"; print $@ if $@; print "\n) " } BEGIN { sub spew { print Dumper(@_) } print ") "'` [download] Presumably you'll have more functions defined than that; consider using Term::Readline or similar if this is something that'll be used a lot. hdp.

eval

% perl -MData::Dumper -nwe 'chomp; 
  ($sub, $rest) = split / +/, $_, 2; 
  eval "$sub($rest)"; print $@ if $@; print "\n) " } 
  BEGIN { sub spew { print Dumper(@_) } print ") "'
