Hi Tom,
It's exactly this issue that forced me to stop using Rebol. Every other
language i've come across allows me to make use of the amazing variety of
command-line tools on UNIX such as ls, grep, locate etc and store the
stdout in a variable for further processing. REBOL/Command lets you do
this but only at a price of US$300.
This is the primary reason why I am trading in REBOL for tcl 'tickle'.
This language has a similar structure to rebol but can access external
commands. For example:
set newline = "\n"
puts "The following users are logged in $newline [exec users]"
This is very similar to rebol syntax except you can merge strings with
variables more easily than using 'print 'form 'rejoin combinations. Tcl
also understands blocks in a similar way to rebol:
REBOL [] ; a REBOL script
foreach number [1 2 3] [
switch :number [
1 [print "One"]
2 [print "Two"]
3 [print "Three"]
]
]
# A tcl script
foreach number {1 2 3} {
switch $number {
1 {puts "one";}
2 {puts "two";}
3 {puts "three";}
}
}
Tcl/Tk also has an excellent windowing system with much clearer syntax
than the 'faces' of REBOL/View.
But best of all Tcl doesn't time out - ever - which in REBOL is driving me
batsh!t. I'm sure many will agree with that last statement if nothing
else.
REBOL is a fantasic language and I love the syntax but problems with
controlling ports, using parse and particularly interacting with external
applications makes it pretty useless for managing UNIX servers, which
is basically what I need. Fortunaetly I can still take advantage of some
of REBOL's better features by calling it from Tcl scripts like this:
exec rebol --do send [EMAIL PROTECTED] "Sorry... Can't afford it";
Like they say Tom, "The right tools for the right job!"
