getMoreArgument()
Returns the additional argument at the specified index.
Syntax
Getopt.getMoreArgument( ind INTEGER )
RETURNS STRING
- ind is the index of the additional argument, from 1 to
getMoreArgumentCount()
.
Usage
After processing all command line options, it is possible to scan for additional command line
arguments, that are not part of the options defined in the GetoptOptions
array of the Getopt
object.
getMoreArgument()
is a method for the Getopt
type, that
returns the additional argument at the specified index, after all possible options defined in the
Getopt
object have been detected.
$ fglrun reduce --verbose --ratio=5 file1 file2 file3
In such case, the --verbose
and --ratio
options must be defined
by the Getopt
object and processed with the getopt() method, while
file1, file2 and file3 are additional
arguments to be processed after the getopt()
loop, using the
getMoreArgumentCount()
method to get the total number of additional arguments, and
the getMoreArgument()
method to retrieve the additional argument.
Example
IMPORT FGL getopt
MAIN
DEFINE g getopt.Getopt
DEFINE cnt, ind INTEGER
...
WHILE g.getopt() == getopt.SUCCESS
...
END WHILE
IF g.invalidOptionSeen() THEN
CALL g.displayUsage(NULL)
EXIT PROGRAM 1
ELSE
LET cnt = g.getMoreArgumentCount()
IF cnt == 0 THEN
DISPLAY "ERROR: No files were provided..."
EXIT PROGRAM 1
ELSE
FOR ind = 1 TO cnt
DISPLAY SFMT("File to process: %1", g.getMoreArgument(ind))
END FOR
END IF
END IF
