[REBOL] Processing files / Any AWK users?
From: greggirwin::mindspring::com at: 18-Nov-2001 20:29
If I'm processing a file, by lines, thus:
foreach line read/lines/with file rec-sep [
It appears that foreach doesn't call read on each pass, but I thought I'd
ask to see if anyone knows, for certain. I know you can modify the block
that foreach uses and it will see the changes, but I wasn't sure what magic
occurs in this scenario.
The real question, I suppose, is: Should I cache the return value from 'read
before using it with foreach, or is that unnecessary?
As a side question, does anyone on the list use AWK or think that something
like it (i.e. an auto-driven rule/action file processor) would be useful?
