[Swift-user] regexp problem

[Antonius Sardjito]

Hi Dr. Wilde,

I am able to readData from the input now, into an array of string.  I am
currently trying to use the strcut and strcat to cut the ".tif" and replace
it with "Colored.tif"

I tried to do something like this:

string cutresult =
@strcut(output[0],"/home/wilde/bigdata/data/modis/output/");
#outfile = eccho(output[0]);
trace(output[0]);


and the error is :
*
RunID: 20100122-0951-345qqi15
Progress:
SwiftScript trace: /home/wilde/bigdata/data/modis/output/h11v05.tif
Execution failed:
        java.lang.IndexOutOfBoundsException: No group 1


I don't understand why I got the error IndexOutOfBounds, I have checked the
string using a procedure that echo the string to a file, and as you can see
from above I also checked it with trace(output[0]) which produces a valid
value.

ps.

This is the whole test file named mini.swift

type file;
file input <"input_for_mini_test.txt">;
string output[] = readData(input);
file outfile <"output_for_mini_test.txt">;
string color = "Colored.tif";

app (file out) eccho (string inputStr)
{
        echo inputStr stdout=@out;
}

outfile = eccho(output[0]);
string cutresult =
@strcut(output[0],"/home/wilde/bigdata/data/modis/output/");
trace(output[0]);

--EOF--
