last_patch89 from vodz:
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.

~ chars - option incongruously.
|
||||
* - option list, called add_to_list(*ptr_from_usaged, optarg)
|
||||
: - separator.
|
||||
Example: du applet can have options "-s" and "-d size"
|
||||
If getopt found -s then -d option flag unset or if found -d then -s unset.
|
||||
For this result you must set bb_opt_complementaly = "s-d:d-s".
|
||||
Result have last option flag only from called arguments.
|
||||
Warning! You can check returned flag, pointer to "d:" argument seted
|
||||
to own optarg always.
|
||||
Example two: cut applet must only one type of list may be specified,
|
||||
and -b, -c and -f incongruously option, overwited option is error also.
|
||||
You must set bb_opt_complementaly = "b~bcf:c~bcf:f~bcf".
|
||||
If called have more one specified, return value have error flag -
|
||||
high bite set (0x80000000UL).
|
||||
Example three: grep applet can have one or more "-e pattern" arguments.
|
||||
You should use bb_getopt_ulflags() as
|
||||
llist_t *paterns;
|
||||
bb_opt_complementaly = "e*";
|

bb_getopt_ulflags (argc, argv, "e:", &paterns);
