>Description:
Note first that this problem also occurs for Mac OS X Snow Leopard and NetBSD
current. I have not yet tested GNU awk.
I use awk(1) to generate test data from Unicode text files.
. i think the best is i show it:
## Input producers
io_unicode_data() {
< unicode/UnicodeData.txt ${TAWK} '
BEGIN {FS = ";" ; OFS = ";"}
# There are no comments in this, but..
/^[[:space:]]*[^#]+$/ {
i = $2
# Ranges must become unrolled, otherwise step on
if (i !~ /, First>/) {
$2 = ""
print
next
}
r1 = sprintf("%d", "0x" $1)
getline
r2 = sprintf("%d", "0x" $1)
$2 = ""
# This gets around a bug in at least "awk version 20070501" as found
# on Slow Leopard: there the range F0000-FFFFD, and only that one,
# will *not* be evaluated unless we do this (once property test came)
# XXX presumably the type system is a bit weird; check other AWKs!
sprintf("%X %X", r1, r2)
[
this is it; UnicodeData.txt contains multiple ranges, but only this one will be
"omitted" without sprintf(), the while() will simply not execute otherwise.
]
while (r1 <= r2) {
$1 = sprintf("%X", r1)
printf "%s\n", $0
++r1
}
}
'
}
>How-To-Repeat:
well..; git clone my S-CText and run `make ucd' with and without the line
`sprintf("%X %X", r1, r2)', compare the resulting `test/sa/t_props.dat' files.
