$0 - Get option
|
|
=====================================================================
|
|
Syntax:
|
|
|
|
$0 [-n[ecessary] <necessary>] [-o[ptional] <optional>]
|
|
[-h[ash] hash] <-p[arameter] <paramlist>|-?>
|
|
|
|
Parameters:
|
|
|
|
necessary : necessary parameter, seperate by space, and can add colon
|
|
(:) if has parameter. Such as "ser: cli:". It also can
|
|
be alias which use '>' for assign to another defined
|
|
option. Such as "server>ser client>cli".
|
|
optional : optional parameter, seperate by space, and can add colon
|
|
(:) if has parameter. Such as "c p l:". It also can be
|
|
alias wich use '>' for assign to another defined option.
|
|
Such as "check>c powerless>p lang>l".
|
|
hash : an address. Only use for Perl program calls. Such as
|
|
\\\%myhash.
|
|
paramlist : A list contains the names or variable's address (only
|
|
for perl program) for store the real value. Such as
|
|
"server client check powerless lang". You also can do
|
|
[\\\$server \\\$client \\\$check \\\$powerless \\\$lang]
|
|
in Perl calls
|
|
|
|
Remark:
|
|
':' : limited one parameter
|
|
|
|
Examples:
|
|
1. Accept -cZ as -c -Z, -f as -full, and -s sourcepath for necessary
|
|
$0 -n "s:" -o "c Z f full>f" -p "sourcepath opt_c opt_z full" %*
|
|
2. Accept -copy f1 [f2], -move f1 f2, -del f1 [...] -tab [...]
|
|
$0 -o "copy:? move:: del+ tab*" -p "copyarg movearg delarg tab"
|
|
3. Accept -f [file] -f [file1] [file2]
|
|
$0 -n "f* " -p "file" %*
