Instead, here's the updated script:
8<===
#!/usr/bin/perl
while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1
entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}
8<===
Run it like this (assuming its saved as sort.pl):
for f in $(find arch/arm -name 'Kconfig*'); do perl sort.pl $f > $f.new \
&& mv $f.new $f && git update-index $f; done
Omit the "git update-index" bit if you don't want to commit the result.
("git update-index" is safer than "git add" for this as "git add" will
add new files, "git update-index" won't without an additional option.
That's not a recommendation to use it though.)
