The following VWST code works fine, however in trying to convert to gst I
cannot find much help
in changing the REGEX line of code.
The problem is to extract all the integers from a text line and sort into
order and print, and NO its not a class test :-),
just a example of string manipulation from a C++ site I think.
I've tried replaceAllRegex:with: and am getting a doesNotUndertstand error
In the small extraction below I'm simply trying to get a regex to suppress (
replace)
any alphas with a space -- without sucess !!
============= gst test =========================
| txt nums |
Transcript cr; show: '*** hiddennumbers.ws '; show: Time now printString ;
cr.
txt := '098m03r9f80239802389f0m9KDKLKLJDKLJm0983m890DMOm03
dlkfj3hljf4h3klhl00000002998'.
Transcript cr; show: txt ; cr.
" // txt := txt copyWithRegex: '[a-zA-Z]' matchesReplacedWith: ' '. " "
vwst code "
txt := txt replaceAllRegex: '[a-zA-Z]' with: ' '.
" gst code "
" replace all alphas with space "
Transcript cr; show: txt ; cr.
========================= execution ====================
$ gst -f hiddennumbers.st
*** hiddennumbers.ws 15:38:46
098m03r9f80239802389f0m9KDKLKLJDKLJm0983m890DMOm03
