Title: "REBOL Script Cleaner"
Author: "Carl Sassenrath"
File: %clean-script.r
Date: 8-Apr-2001
Patch: [
{original} [
parse script blk-rule: [
some [
str:
...]]]
{changed to} [
parse script blk-rule: [
any [
str:
...]]]
]
Email: [EMAIL PROTECTED]
Purpose: {
Cleans REBOL scripts by parsing the REBOL code
and supplying standard indentation and spacing.
}
Note: {
This script produces STANDARD script indentation and
spacing. No doubt you will want to modify it to use
your own rules. Send your enhancements and I will
consider adding them to the distribution... but keep
this header intact and keep the code clean. No hacks.
