MORE REBOL/Power-Tools
Here's some more REBOL/Power-Tools DE-SPACE & RE-SPACE
These functions remove & replace all whitespace characters
from a string! or file!
White-space is interchanged for Hex %20 value just like
in a REBOL file path!
Very useful for PARSING purposes, enables string values to
remain intact whilst separating other values by whitespace.
Anyway here's the functions;
DE-SPACE: func [ "REPLACES ALL WHITE-SPACE CHARACTERS WITH A HEX
VALUE" target [ string! file!]] [ if (type? target) = file! [
target: read target] replace/all target " " "%20"]
RE-SPACE: func [ "REPLACES ALL HEX %20 VALUES WITH WHITE-SPACE
CHARACTER" target [ string! file!]] [ if (type? target) = file! [
target: read target] replace/all target "%20" " "]
here's some examples;
>> a: de-space " this silly stupid string "
== {%20this%20%20%20%20silly%20%20%20stupid%20%20%20string%20%20}
>> a
== {%20this%20%20%20%20silly%20%20%20stupid%20%20%20string%20%20}
>> re-space a
== " this silly stupid string "
>> parse a none
== ["this" "silly" "stupid" "string"]
>> parse de-space a none
== [{%20this%20%20%20%20silly%20%20%20stupid%20%20%20string%20%20}]
>> de-space %readme.txt

Here's a function that return an ASCII value or block of values
for a char! string! or file! { note file contents )
ASCII: func [ "RETURNS ASCII INTEGER VALUES" value [ char! string!
file! ]] [
if (type? value) = file! [value: read value]
if (type? value) = char! [ return to-integer value]
count: length? value
value-block: [] clear value-block
loop count [ append value-block to-integer pick value 1 value: next
value ]
return value-block
]
some examples;
>> ascii #"A"
== 65
>> ascii "A"
== [65]
>> ascii "APPLES"
== [65 80 80 76 69 83]
>> ascii %./guicon013/readme.txt
== [71 85 73 99 111 110 32 40 97 107 97 32 67 111 110 115 111 108 101

Feel free to add your own Power Tools & Functions.
still lots more to come,
PS -- Ralph Roberts, glad you liked my directory functions, thank you for
your kind words, it feels good to feel like I've done something good for a
change.
Sorry everybody for the big spat over the last few days, I don't like or want
religious wars in REBOL either!.
