[REBOL] to-string do question?
From: bry::itnisk::com at: 22-Jul-2003 12:10
I would like to do a string, the result of that do operation I would
then like to convert to-string.
From the console
>> thisstring: "1 + 5"
== "1 + 5"
>> do thisstring
== 6
>> thisstring: "write %newfile.txt read %result.txt"
== "write %newfile.txt read %result.txt"
>> do thisstring
>> thisstring: "1 + 5"
== "1 + 5"
>> to-string do thisstring
== "6"
>> thisstring: "write %newfile.txt read %result.txt"
== "write %newfile.txt read %result.txt"
>> to-string do thisstring
** Script Error: to-string is missing its value argument
** Where: halt-view
** Near: to-string do thisstring
>>
so what I would like is someway of having do return "True" or "False" if
do does not produce any output.
I was thinking it might be possible to have a function that did the
following: if do returns error returnstring = "False" else if to-string
do thisstring returns error then returnstring = "True" else returnstring
= to-string do thisstring.
However I wanted to ask before I start writing the code as I thought I
might be missing something.
