Manuel,
I rewrite bb_getopt_ulflags() function for more universal usage.
My version support now:
- options with arguments (optional arg as GNU extension also)
- complementaly and/or incomplementaly and/or incongruously and/or list
options
- long_opt (all applets may have long option, add supporting is trivial)
This realisation full compatibile from your version.
Code size grow 480 bytes, but only coreutils/* over compensate this size
after using new function. Last patch reduced over 800 bytes and not full
applied to all. "mkdir" and "mv" applets have long_opt now for demonstrate
trivial addition support long_opt with usage new bb_getopt_ulflags().
Complementaly and/or incomplementaly and/or incongruously and/or list options
logic is not trivial, but new "cut" and "grep" applets using this logic
for examples with full demostrating. New "grep" applet reduced over 300
bytes.
Mark,
Also. I removed bug from "grep" applet.
$ echo a b | busybox grep -e a b
a b
a b
But right is printing one only.
